In accordance with the object of the present invention there is provided a problem-setting service method on network, the method comprising the steps of prompting a question preparation user to start a question preparation client terminal for constitution of new questions from the question preparation client terminal, prompting the question preparation user to connect via a communication network the question preparation client terminal to a question service providing server located on a predetermined network route, thereby transmitting prepared questions to the server, prompting the question service providing sever to store questions received from the question preparation client terminal trough the communication network, prompting a question solution user to connect via a communication network a question solution client terminal to the question service providing server, thereby requesting a question provision, prompting the question service providing server to transmit to the question solution client terminal the questions requested from the question solution client terminal via the communication network, and prompting the question solution client terminal to store the questions transmitted from the question service providing server and to display the questions stored in response to manipulation of the question solution user and to store answers solved by the question solution user

The present invention may further comprises the steps of preparing repetitive questions wherein the question service providing server creates repeated questions where arranged orders or parameters of each sentence relative to identical learning contents for each item of stored questions are changed, and transmitting requested repetitive questions to the question solution client terminal via the communication network when there is a request from the question solution client terminal connected through the communication network.

Now, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Figure 1 is a schematic block diagram of a hardware for performing the present invention, where the hardware for performing the present invention includes a question service providing server 10, a question solution client terminal 20 (hereinafter referred to as question solution terminal), a question preparation client terminal 30 (hereinafter referred to as question preparation terminal) and a domain storage unit 40. The question service providing server 10, the question solution terminal 20 and the question preparation terminal 30 are inter-connected via communication network such as internet or the like.

The question service providing server 10 cumulatively stores question service providing program, question data, test result data inclusive of participants' examination results for each question, user information such as name, address, email address, occupation, interested fields and the like, evaluation of users related to quality of questions with reference to each question and referral frequency, and other question information with reference to affiliated fields and nature of questions. The question service providing server 10 transmits question lists and questions to the question solution terminal 20 and provides existing question information to the question preparation terminal 30.

At this time, the question service providing program is so programmed that questions are transmitted, questions are input, stored and read out via communication network, user registration and log-in are performed, low-leveled questions are removed based on question information, and update function for maintaining question data is performed. The question solution terminal 20 has a built-in question solution client program, selects questions according to question lists provided from the question service providing server 10 and inputs code and user information to perform user log¬

The question solution client program serves to receive questions to display each question and embody pictures and sounds thereof, enabling to understand question solution processing state easily The question solution client program is so programmed as to perform a function of transmitting to server state display frame, hint and help guide, test result and test level

The question preparation terminal 30 is inherently equipped with a question preparation client program, and either reads out existing questions from the question service providing server 10 to edit or same and transmits newly-prepared questions These new editions or revised questions dre transmitted to the question service providing server 10

The question preparation client program is so programmed as to performing functions of creating new questions per kind, searching errors of the created questions for debugging, storing and reading out questions from an domain storage unit 40, reading out and transmitting questions from the question service providing server 10

The domain storage unit 40, a storage medium directly connected to the question preparation terminal 30, serves to store and read out question data stored in response to request from the question preparation terminal 30

Now, operational examples of the present invention operated through the hardware thus constructed will be described in detail with reference to Figures 1 to 5

An approximate signal input/output process among the question service providing server 10, question solution terminal 20 and the question preparation terminal 30 is depicted in Figure 2, and to begin with, operational process of the question service providing server 10 is described with reference to Figures 3a and 3b where discrimination process out of control operations explained below is performed by a main processor (not shown) inherently equipped in the question service providing server 10 form controlling the entire operations, which is the known art and omitted in additional explanation thereto

When a power is applied, the question service providing server 10

(hereinafter referred to as server) loads and drives the question service providing program and performs an initialization process where database stored therein with question data is loaded, step S10, and transforms the initialization mode to an input waiting mode for responding to inputs from each client terminal, step S20

The server 10 under the input waiting mode discriminates whether there is any new account request of a new user from the question solution terminal 20 or the question preparation terminal 30, step S30, and performs a new account handling of a new user if there is a new account request from the new user, step S40

When the new account handling of the new user is executed at step S40, the server 10 receives user information from the question solution terminal 20 or question preparation terminal 30 according to a predetermined input format to check whether there is any discrepancy in an entry format such as errorneous entry of contents in the input user information or omitted items in compulsory entry items When there is discrepancy in the entry format, making it impossible to create an account, a guide message is transmitted to a related corresponding terminal for advising that creation of account has been rejected

When there is no discrepacy in the entry format, a new account is created for new user and the user is registered in the database and a guide message is transmitted to the related corresponding terminal indicating that a new account has been established

Successively, the server 10 checks whether there is a log-in request from the question preparation terminal 30, step S50, and as a result of the check, if there is a log-in request from the question preparation terminal 30, user information (by way of example, name, secret number, etc ) requested of log-in from the question preparation terminal 30 and registered user information are compared, and log-in is performed in response to the compared result, step S60

At step S70, the server 10 discriminates whether the log-in has been successfully executed according to execution result at step S60 As a result of the discrimination at step S60, if the log-in has been unsuccessful, a guide message is sent to the question preparation terminal 30 informing that the log-in has been failed, step S80 and a subsequent step S140 is processed for checking whether there has been a log-in request from the question solution terminal 20

Meanwhile, if the log-in has been successful as a result of discrimination at step S70, the server 10 checks whether there is a request from the question preparation terminal 30 for allowing reading the previously prepared questions, step S90, and if there is no request for question reading as a result of discrimination at step S90, a subsequent step S110 for checking whether there is a writing request is processed When there is a question reading request from the question preparation terminal 30, the reading question requested from the question preparation terminal 30 is searched from the database to send same to the question preparation terminal 30, step S100

Successively, the server 10 discriminates whether there is a writing request from the question preparation terminal 30 relative to newly prepared questions or questions edited from existing questions, step S110, and as a result from the discrimination at step S110, if there is no writing request from the question preparation terminal 30, flow is proceeded to a subsequent step of step S130 for checking whether log-out of the question preparation terminal 30 has been performed, and if here is a question writing request, the requested questions are added to the database, step S120

The server 10 then checks whether the question preparation terminal 30 is logged out, step S130 and if the question preparation terminal 30 has not been logged out, flow returns to step S90 for checking whether there is a reading request When the question preparation terminal 30 has been logged out, flow advances to step S140 for discriminating whether a log-in was requested from the question solution terminal 20

At this time, the server 10 handles the log-out when a log-out signal is transmitted from the question preparation terminal 30 and when the question preparation terminal 30 is disconnected, and when there is no signal input from the question preparation terminal 30 for a predetermined period of time

Successively, the server 10 discriminates whether there is a log-in request from the question solution terminal 20, step S140, and when there is a log-in request from the question solution terminal 20 as a result of the discrimination, user information (by way of example, name, identification code, secret number, etc ) requested for log-in from the question solution terminal 20 and registered user information are compared and log-in treatment is performed as a result of the comparison thereof, step S150

The server 10 discriminates step S160 whether or not the log-in has been successful in response to treatment result at step S150, and if the log-in is unsuccessful as a result of the discrimination at step S160, a guide message is sent to the question solution terminal 20 indicating that the log-in has failed, step S170, and flow returns to step S20 for waiting to reply to input from client

Meanwhile, as a result of discrimination at step S160, if the log-in has gained success, the server 10 checks whether transmission of question list is requested from the question solution terminal 20, step S180, and if there is no request of question list as a result of the check at step S180, flow advances to step S200 for checking whether the question transmission has been requested

If there is a transmission request of question list from the question solution terminal 20 as a result of check at step S180, the server 10 transmits the request question list to the question solution terminal 20, step S190

Successively, the server 10 discriminates whether there is a transmission request from the question solution terminal 20 relative to questions selected from the list, step S200, and if there is a question transmission request from the question solution terminal 20 as a result of discrimination at step S200, personal information (such as identification code, name and the like) of the user who has logged in is input according to predetermined stipulations and discrimination is made as to whether transmission requested question is a question accessible by the user who has logged

As a result of the discrimination at step S210, if the requested question is a question beyond the accessible domain of the user who has logged in, the flow proceeds to next step S220 for transmitting to the question solution terminal 20 a guide message that the question transmission is impossible and, if the requested question is a question within accessible domain of the user who has logged in, a comparison is made between a current time and a pre-established question solution effective time (established by a server manager or question preparation user) to check if question solution by the user is currently the effective time, step S215 As a result of discrimination at step S215, if the current time is not an effective time of question solution by the user, the server 10 transmits to the question solution terminal 20 a guide message advising that the question transmission is impossible, step S220, and if the current time is an effective time of question solution by the user the server 10 searches the requested question from the database to transmit same to the question solution terminal 20, step S230

Successively, the server 10 discriminates whether there is a writing request from the question solution terminal 20 about subjective evaluation value of the question solution user relative to grading result, question level, degree of difficulty and the like, step S240, and if there is no writing request as a result of the discrimination at step S240, flow advances to step S260 for discriminating whether the question solution terminal 20 has been logged out

If there is a wπting request, a comparison is made between a current time and a prior established writing effective time (established by a server manager or question preparation user) and discrimination is made as to whether the current time is a writing effective time by a user, step S244

As a result of discrimination at step S244, if the current time is not the writing effective time by the user, the server 10 performs a writing impossible treatment, step

S248, and if the current time is an effective writing time by the user, the server 10 adds to the database the grading result and the subjective evaluation value of the user transmitted from the question solution terminal 20, step S250

The server 10 then checks whether the question solution terminal 20 has been logged out, step S260, and if the question solution terminal 20 has not been logged out, flow returns to step S180 for whether there is a transmission request of question list, and if the question solution terminal 20 has been logged out, flow returns to step S20 for waiting to reply to input from client Now, operational control procedure of the question preparation terminal 30 will be described with reference to Figures 4a and 4b It should be noted that the present embodiment relates to a operational control procedure where the question service providing server 10 is established with an account of question preparation user, and a discrimination procedure among the below-mentioned control operations is done by a mam processor (not shown) installed in the question preparation terminal 30 and for controlling the entire operation, which is a well-known art, such that additional explanation thereto will be omitted

First of all, when a question preparation user applies power to the question preparation terminal 30 to start to question preparation terminal 30, the started question preparation terminal 30 loads operation program and question preparation client program from a built-in memory to a main memory to enable a new question preparation and editing operation of existing questions, which is shown on terminal screen as menu for selecting same, step S310

The initialized question preparation terminal 30 checks whether the question preparation user will perform the question preparation operation, step S320, and if the question preparation user does not select the question preparation operation from the menu on the screen as a result of check at step S320, flow proceeds to a subsequent step of S340 for checking whether the user has selected server 10 connection

Meanwhile, when the question preparation user selects the question preparation from the menu on the screen to prepare new question, the question preparation terminal 30 stores the questions prepared by the user at the domain storage unit 40, step S330

Now, more detailed explanation thereto is given as below

The question preparation client program displays a predetermined form of question preparation format inter-exchangeable with question service provision format of the question service providing server 10, and when a user prepares questions through the question preparation format to select the storage thereof, the prepared questions are stored in the area storage 40

By way of example, the question preparation format may be a subjective question or a objective question, and a certain type of format corresponding to the question preparation client program is displayed, on the question preparation terminal 30 according the user's selection

Successively, the question preparation terminal 30 discriminates whether the question preparation user has selected connection with the server 10 from the menu on the screen, step S340, and as a result of the discrimination at step S340, if the user has not selected the connection with the server 10, control operation is terminated

If the user has selected the server connection, communication program connected to an emulator intrinsically equipped at the question preparation client program, web browser or a separate plug-in is driven to be connected to the server 10 via a communication network, step S350

When connection with the server 10 is made at step S350, the question preparation terminal 30 transmits to the server 10 user information (by way of example, name, identification code and secret number, etc ) input by the user on the manu to request a log-in, step S360

The question preparation terminal 30 discriminates whether a message has arrived from the server 10 regarding whether the log-in has been successful, step

S370, and if a message indicating that the log-in has be unsuccessful is input, the question preparation terminal 30 presents a message on the screen to allow the user to select a re-try, step S380, and if the user selects a re-try, flow returns to step S360 to request a log-in again and if the user does not select the re-try, the control operation is terminated.

If a message indicative of the log-in being successful at step S370, arrives from the server 10, the question preparation terminal 30 discriminates whether the user has selected a "question writing" from the menu, step S390, and if the user has not selected the question writing, flow advances to the subsequent step of step S410 for discriminating whether the user has selected a "question reading".

Meanwhile, if the user has selected the question writing at step S390, the question preparation terminal 30 reads out from the domain storage unit 40 the newly prepared or edited questions the user desires to write on the server 10 to transmit same to the server 10, step S400.

Successively, the question preparation terminal 30 discriminates whether the user has selected the question reading priorly prepared from the server 10, step S410, and if the user has not selected the question reading, flow proceeds to step S470 to check whether the user has selected the log-out.

If the user has selected the question reading at step S410, the question preparation terminal 30 requests the server 10 to transmit a question file selected by the user, step S420 and checks whether the requested question file has been transmitted from the server, step S430.

If the requested file is not transmitted from the server 10 within a predetermined period of time at step S430, the question preparation terminal 30 presents a message on the screen to allow the user to select whether to re-try the question file request, step S440, and if the user selects the re-try, flow returns to step S420 to re-request the question file transmission and if the user has not selected the re-try, flow advances to the subsequent step of S470 for discriminating whether the user has selected the log-out.

If the requested question file has been transmitted from the server 10 at step

S430, the question preparation terminal 30 discriminates whether the user has selected an editing function with regard to the file transmitted from the menu, step

S450, and if the user has not selected the question editing, flow proceeds to the subsequent step of S470 for discriminating whether the user has selected the log-out.

Meanwhile, if the user has selected the editing of questions transmitted from the server 10 at step S450, the question preparation terminal 30 displays questions to be edited according to the selection of the user, and if the user corrects or edits contents of corresponding questions to select the storage, the corrected or edited questions are stored in the domain storage unit 40, step S460.

Successively, the question preparation terminal 30 discriminates whether the user has selected the log-out, step S470 and if the user has not selected the log-out, the question preparation terminal 30 returns to step S390. However, if the user selects the log-out, the question preparation terminal 30 transmits a log-out signal to the server 10 and stops connection with the server 10, step S480, to terminate the control operation.

Meanwhile, the question preparation user may designates a date or a time when the question solution user solves questions, or designates a time consumed for solving the questions.

By way of example, when the question preparation terminal 30 transmits questions to the server 10 for registration, a predetermined format provided from the question service providing server 10 is designated with test date, and when time or solution time for each question corresponding thereto, or when a test date and time for corresponding questions are designated in a predetermined format in the questions, the question service providing server 10 registers the test date and time designated by the question preparation user with database such that the corresponding questions can be supplied to the question solution user on a designated date and time

Now, operational control procedure of the question solution terminal 20 will be described with reference to Figures 5a and 5b

It should be noted that the present embodiment relates to a operational control procedure where the question service providing server 10 is opened with a question preparation user's account, and discrimination procedure in the following control operation relates to a main processor (not shown) intrinsically equipped within the question solution terminal 20 for controlling the entire operations, which is well known art such that additional explanation thereto will be omitted

First of all, when a question solution user applies a power to the question solution terminal 20 to start the terminal 20, the started question solution terminal 20 loads from a built-in memory the operational program and question solution client program to a main memory to allow the question solution in an able state, such that a menu for selection thereof is indicated on a screen of the terminal, step S510

The initialized question solution terminal 20 discriminates on the menu of the screen whether the question solution user has selected connection with the server 10, step S520, and as a result of the discrimination at step S520, if the user has not elected connection with the server 10, control operation is terminated

If the user chooses the server connection, a communication program connected to a communication emulator intrinsically installed with in the question solution client program or a separate plug-in is driven to be connected with the server 10 via a communication network, step S530

If the server 10 is connected at step S530, the question solution terminal 20 transmits to the server 10, a user information (by way of example, name, identification code, secret number, etc ) input by the user on the menu to request a log-in, step S540

Successively, the question solution terminal 20 discriminates whether a message has been received from the server 10 regarding whether the log-in has been successful, step S550, and when a message indicating failure of the log-in is input, the question solution terminal 30 presents a message on the screen to allow the user to select a re-try, step S560, and if the user has elected the re-try, flow returns to step S540 to re-request the log-in, while, if the user has not chosen the re-try, the control operation is terminated

It a message arrives from the server 10 indicating that the log-in has succeed, the question solution terminal 20 requests transmission of question list to the server 10, step S570

Next, the question solution terminal 20 checks if the question list requested has been received from the server 10, step S580, and if the question list requested from the server 10 has not been transmitted, a message is presented on the screen to allow the user to select the re-try, step S590, and if the user elects the re-try, flow returns to step S570 to re-request the question list and if the user has not selected the re-try, control operation is terminated

If the question list requested in step S580 arrives, the question solution terminal 20 displays the transmitted list to allow the user to select questions desired thereby, step S600, and if the user select questions desired to be solved, a signal requesting transmittal of the questions selected by the user is dispatched to the server 10, step S610

Successively, the question solution terminal 20 discriminates whether the questions requested from the server 10 have been transmitted step S620, and if the questions requested from the server 10 have not been received, a message is indicated on the screen to allow the user to re-try, step S630, and if the user has selected the re-try, flow goes beck to step S610 to request transmitted of reselected questions If the user does not select the re-try, control operation is terminated

If the requested questions have been transmitted from the server 10 at step S620, the question solution terminal 20 displays one by one the transmitted questions according to the user's selection and each solution per question is stored by the user, step S640

By way of example, if test time per question is designated, each corresponding question is displayed only for the designated time, and if display time is confined to each question, each question is displayed only on the restricted time and no re-display is performed

At the same time, the question solution terminal 20 compares corrected answers with corresponding answers solved by the user for each question and awards marks, step S650

By way of example, in case of objective test, predetermined marks are given and awarded only if answers solved by the user accord with the answers of corresponding questions In case of subjective test, concurrence or consistency of words between answers solved by the user and answers of corresponding questions are checked, and marks are awarded in response to ratios of accordance words

The question solution terminal 20 displays items inputtable in subjective evaluation values such as list of questions solved by the user upto the present time, level of each question, degree of difficulty, etc when one question is transformed to another question or when the user selects termination relative to solution of the questions, step S660, and transmits to the server 10 evaluation values for each question, step S670

At this time, when the question solution terminal 20 is in the state of being connected to the server 10, the evaluation values for each question input by the user is immediately transmitted to the server 10, and when the question solution terminal 20 is not in the state of being connected to the server 10, the values are stored in an auxiliary memory or the like in the terminal 20 and the values for each question stored in the auxiliary memory or the like are transmitted to the server 10 when question solution terminal 20 is connected to the server 10

Successively, the question solution terminal 20 transmits a log-out signal to the server 10 and simultaneously stops connection with the server 10, step S680, to terminate the control operation

Meanwhile, according to a second embodiment of the present invention, the question service providing server 10 creates repeated inquiring questions where arranged order or parameter are changed relative to identical items for the stored questions, which are transmitted to the question solution terminal 20, and answers received from the question solution terminal 20 are compared marked with correct answers, and items may be moved according to marking results or question service may be provide for adjusting the degree of difficulty

The second embodiment thus described according to the present invention will be described with reference to Figures 6 and 7

The question service providing server 10 for performing the second embodiment of the present invention includes a software module 11 for presenting questions to a question solution user, marking the presented questions and controlling information, such as test participation information per question solution user and scores, and a database module 12

As illustrated in Figure 6, the software module 11 may include a question setting unit 11-1 for picking up items for each question module, a test unit 11-2 for displaying the questions constructed by the question setting unit 11-1 on a screen of browser at the question solution terminal 20 and a study progressing unit 11-3 for presenting one by one the questions constructed by the question setting unit 11-1 according to a prior-established predetermined order to take charge of study progress such as comparing answers solved by the question solution user with correct answers for scoring the test

By way of example, the question setting unit 11-1 and the study progressing unit 11-3 may be applets which are application program executed on a browser at the question solution terminal 20, and the test unit 11-2 may be a servlet which is a program executed through a browser in response to request from the question solution user.

Furthermore, the database module 10 may be comprised of a question module database 12-1 for controlling set-to-be questions per module and a study information database 12-2 for adjusting and controlling test results such as scores and spent time of a question solution user

First of all, the second embodiment of the present invention is started by a question solution user who starts the question solution terminal 20 to be connected to the question service providing server 10 via a communication network

At this time, component files of web pages for providing study contents are downloaded from the question service providing server 10 to the question solution terminal 20, and a mam picture of web page for study progress provided from the question service providing server 10 is displayed on a display screen of the question solution terminal 20

By way of example, web page opened at the question setting computer 10 is desire able to be made in Hypertext Markup Language but may be made in any format as long as it can be read out by computer system

Next, the question service providing server 10 validates identity of a connected question solution user

By way of example, when a question solution user inputs his or her membership identification code and pass word in an initial screen, the question service providing server 10 compares same with registered member information to treat it as successful log-in or failed log-in, and when it is treated as failed log-in, there is no way of participating in study or learning such as question solution, step S710

Meanwhile, if a question solution user is a new member who has not registered for membership, a new membership registration can be made on a mam screen In new registration, his or her personal particulars, desired identification and password can be listed where, the question service providing server 10 allows him or her to become a new registered member as long as there is no discrepancies in information of the question solution user input in the course of membership entry

Successively, when a question solution user selects a desired study (learning) subject of a mam screen of web page, the question service providing server 10 creates repeated inquiry type questions changed in style and parameter against each study subject and presents same to the question solution user one at a time, in other words, transmits same to the question solution terminal 20, step S720 and counts time, step S730 When questions are presented, various question patterns such as formula type, order type, matching type, logic type, "OX" type and the like may be used By way of example, in case of formula type such as "1 added by 2 equals •• •?", each value of parameter corresponding to "1" and "2" is changeably inserted at each repetition, and in case of "OX" type, orders of correct answer and wrong answer are randomly changed at each repetition In case of logic type, a given result may be made to come out in different way according to assumption

As mentioned above, a question solution user is given with repeated inquiry type questions where arranged orders and parameters of each sentence are changed at every turn against identical study contents for each item, such that the question solution user can fully understand related study contents through the repeated learning method

Successively, the question service providing server 10 receives answers solved by the question solution user from the question solution terminal 20 via a communication network, step S740, and compares same with correct answers of corresponding questions which are previously stored, step S750

As a result of comparison at step S750, if the question solution user is correct in answers, the question service providing server 10 increases a count value of repeated frequency by "1", step S760, compares a repeated frequency counted upto the present time with a predetermined established frequency, step S770 As a result of comparison at step S770, if the repeated frequency counted upto the present time is less than the established frequency, flow returns to step S720 for generating and setting questions

Meanwhile, as a result of comparative result at step S770, if the repeated frequency counted upto the present time is above the established frequency, flow moves to next item of question, step S780 where value of repeated frequency counted upto the present time and counted time are reset, step S790

Successively, the question service providing server 10 discriminates whether the question solution user selects a study (learning) discontinuance, step S800, and if the question solution user has selected the study discontinuance, the server stops the study Meanwhile, if the question solution user has not selected the study discontinuance, flow returns to step S720 to create and set a repeated inquiry type question relative to study contents of next item of question decided at step S780

If the answers solved by the question solution user at step S750 are not the correct answers, the question service providing server 10 checks a time spent for solving the question of present item, step S810, and if the time consumed for solving the present item of item does not surpass a predetermined limited time, flow returns to step S720 to create and set a question of repeated inquiry type question relative to the present item of question

Meanwhile, if the time consumed for solving the question of present item has surpassed a predetermined limited time at step S820, the question service providing server 10 displays a user interface screen for questioning whether the question solution user has an intention of continuing the present study of question, step S830, allowing the question solution user to decide through the user interface screen, step S840

As a result of discriminative result at step S840, if the user has selected a continuous progress of study, in other words, if a response signal indicatiion of continuous progress is received from the question solution terminal 20, flow returns to step S720 to create and set a question of repeated inquiry type question relative to the present item of question

Meanwhile, if the question solution user has not selected the continuous progress at step S840, the question service providing server 0 marks the present item of question as "unfinished", step S850, where flow advances to step S780 to create and set a repeated inquiry type question for next item of question

Meanwhile, according to the second embodiment of the present invention, construction may be made in such way of setting questions to the question solution user that questions are grouped per stage according to degree of difficulty thereof, where the question service providing server 10 first sets questions belonging to a group of predetermined state of difficulty determined by selection of the question solution user, pnorly-evaluated capability of the question solution user or study progress mode, and gradually increases the stage of degree of difficulty

At this time, study or learning capability of the question solution user is calculated at each stage and degree of difficulty is adjusted in response to the calculated study (learning) capability By way of example, if the study capability of the question solution user is less than a predetermined value at a predetermined stage, flow may not advance to next degree of difficulty but return to a prior stage

Furthermore, the study (learning) capability may be calculated in consideration of more than at least one of the two points which are marking or hitting rate relative to repeated inquiry type question per item at each corresponding state and consumed time of solution

By way of example, (a) Method where, if a question solution user starts from a lowest degree of difficulty per study subject to solve questions within a designated period of time and as many as designated frequencies, the user advances to next stage in the degree of difficulty otherwise flow returns to a prior stage

(b) If the user starts from a question with a middle degree of difficulty per study subject to solve questions within a designated period of time and as many as designated frequencies, the user proceeds to a question of next stage in the degree of difficulty otherwise flow returns to a prior stage

(c) If the user starts from a question with a highest degree of difficulty per study subject to solve questions within a designated period of time and as many as designated frequencies, the user advances to a question of next stage in the degree of difficulty otherwise flow returns to a prior stage

(d) If the user cannot solve each question within a given period of time and as many as given frequencies, study or learning may proceed where at least one certain method is selected out of methods of solving particular questions or each method is mixed for study

(e) Furthermore, selections are made from questions not solvable at stages of reviewing the previous study and questions which need reviews through comparative analysis between attempted frequencies and frequencies of correct answers, and progress may be made into review mode of re-study

The above-mentioned methods can be effective for cases where studies are progressed, divided into beginner level, intermediate level and advanced level

As the study is progressed, a beginner starts from a lowest level of difficulty while a user of an intermediate level starts at an intermediate level of difficulty while a user of an advanced level starts study from a relatively high level of difficulty However degree of difficulty for study level to be advanced in response to study capability calculated per stage should be adjusted, and as circumstances may require, a user of an intermediate level may proceed to a beginner level, or a user of high level may advance to a beginner level

Having described preferred embodiments of the invention with reference to the accompanying drawing, it is to be understood that the various changes and modifications may be effected therein by one skilled in the art without departing from the scope or spirit of the invention as defined in the appended claims
