Abstract

PROBLEM TO BE SOLVED: To improve a result of study, maintenance of will to study, and an efficiency of study in a correspondence course system for performing study using various collections of questions. SOLUTION: A list of incorrect answers and untouched questions is transmitted to a client 3 from a server via the Internet 5, and a student selects a question from this list at the client 3 and transmits it to the server 2. At the server 2, this question is distributed to the client 3, and the student solves this question at the client 3 and transmits the answer to the server 2. The answer is marked at the server 2 and the result of the marking is transmitted to the client 3, and when this answer is correct, this question is deleted from the list of the incorrect answers and untouched questions. This result of the marking is displayed on a liquid crystal display 33 at the client 3. In such a manner, the student can concentrate him-/herself only on a question that he/she has never answered correctly and touched, and every time when he/she answers a question, the statistic data is instantly obtained in real time.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] The present invention relates to a communication system in which one or more clients are connected to a server through a communication network.
The present invention relates to a distance learning system for learning online based on various kinds of problem collections such as qualification examinations, university entrance examinations, and high school entrance examinations.

[0002]

2. Description of the Related Art Conventionally, in a correspondence education system of this kind, a collection of problems is distributed from a server to each client via a communication network, and each student solves all the problems in the collection of problems and answers the client to the server. It is known that when an answer is sent, each of these answers is scored and given a score, and then sent back from the server to the client along with statistical data such as an average score and a deviation value of all students.

[0003]

However, this has the following disadvantages.

[0004] First, your score and the average score of all students,
Even if the deviation value is known, it is only possible to grasp the position of oneself among all the students, and it is unclear which problem oneself stumbled on. For this reason, questions that could not be correctly answered are often left without understanding, and the learning outcome is not so high.

Second, since the data cannot be totaled until the last student sends the answer, it takes a certain time for the statistical data to be determined, during which time there is a possibility that the willingness to learn is reduced.

Third, since important questions for the student and questions that are not are presented randomly, the student is forced to uselessly learn and cannot learn very efficiently.

[0007] In view of such circumstances, the present invention clearly distinguishes a problem that the user could not answer correctly from a problem that the user can correctly answer, thereby improving the learning result. It is an object of the present invention to provide a distance learning system that is maintained and eliminates problems that are not important to students, thereby increasing the efficiency of learning.

[0008]

That is, according to the present invention, in a correspondence education system (1) in which a client (3) is connected to a server (2) through a communication network (5), a table of contents of unanswered / unstarted questions is obtained. From the server to the client via the communication network to send to the client, on the client side, select a question from the table of contents of this unanswered / unstarted question and send it to the server, on the server side,
Distribute this question to the client, solve the problem on the client side, send the answer to the server, and on the server side, score the answer and send the scoring result to the client, When the answer is correct, the question is deleted from the table of contents of the unanswered / unstarted question, and the client side displays the scoring result.

[0009] By adopting such a configuration, each time a student solves a problem and corrects it, the number of uncorrected and unstarted problems is reduced, and problems that have never been correctly answered and problems that have not been started yet are reduced. At the same time, every time a single question is solved, statistical data as well as correct and incorrect answers to the answer can be obtained instantaneously in real time.

Further, according to the present invention, in a correspondence education system (1) in which a client (3) is connected to a server (2) through a communication network (5), a table of contents for priority designation in which only important issues are designated is prepared. Transmitting from the server to the client via the communication network, on the client side, selecting a problem from the table of contents for the emphasis designation, transmitting the problem to the server, and distributing the problem to the client on the server side, On the client side, solve this problem and send the answer to the server, on the server side, score this answer and send the scoring result to the client, and display the scoring result on the client side It is configured so that

With this configuration, the student can concentrate on only the important questions selected as the key questions, and at the same time, every time one question is solved, another correct answer / incorrect answer to the answer is given. Besides, statistical data can be obtained instantaneously in real time.

Further, according to the present invention, in a correspondence education system (1) in which a client (3) is connected to a server (2) through a communication network (5), an uncorrected / unstarted course is selected on the client side. Sometimes, the table of contents of the unanswered / unstarted question is transmitted from the server to the client via the communication network, and the client selects a question from the table of contents of the uncorrected / unstarted question and transmits it to the server. Delivering the question to the client on the server side, solving the problem on the client side and sending the answer to the server,
On the server side, the answer is scored and the scoring result is sent to the client, and when the answer is correct, the question is deleted from the table of contents of the uncorrected / unstarted question, and the client side deletes the question. And displaying the scoring result, and when a priority designation question course is selected on the client side, a table of contents for priority designation specifying only important questions is transmitted from the server to the client via the communication network. Then, on the client side, a problem is selected from the table of contents for the priority designation and transmitted to the server, the server distributes the problem to the client, and the client solves the problem and solves the problem. Send the answer to the server, and on the server side,
The answer is scored, the score is transmitted to the client, and the score is displayed on the client side.

[0013] With this configuration, if the student proceeds along the uncorrected / unstarted problem course, the number of uncorrected / unstarted problems decreases each time the student solves the problem and corrects the answer. Students can concentrate on only the questions that they have not answered correctly and have not yet started, and if they follow the Focused Assignment Course, they will learn only the important issues that they have selected In addition to being able to study intensively, in any course of study, every time you solve a problem, you will be able to obtain the correct / incorrect answer and other statistical data for the answer in real time and instantly. Become.

Further, according to the present invention, in response to the table of contents being transmitted from the server (2), the client (3) outputs the table of contents together with the correct answer rate of all students at the present time of each question to an output device ( 33). With this configuration, the student can estimate the difficulty level of each question by referring to the correct answer rate of each question in real time.

It should be noted that reference numerals in parentheses are for convenience of representing corresponding elements in the drawings, and therefore, the present invention is not limited to the description on the drawings. The same applies to the column of “Claims”.

FIG. 3B is a diagram showing an example of a table of contents of unanswered / unstarted questions, and FIG. That.

As shown in FIG. 1, the distance learning system 1 includes a server 2 and one or more (four in FIG. 1) clients 3. The server 2 and the client 3 are respectively connected to a communication cable. It is connected to the Internet 5 via 25 and 35.

This server 2 has a computer 21,
The computer 21 has a keyboard 22 and a liquid crystal display 23.
And the magnetic disk 24 are connected. The magnetic disk 24 has a collection of questions, a correct answer table, a table of uncorrected / unstarted problems, a table of contents for priority designation, an uncorrected / unstarted problem learning program PRG1 shown in FIG. 2, a priority designation program PRG2 shown in FIG. Focused learning program PR shown in Fig. 4
G3, a correct answer rate calculation program PRG4 shown in FIG. 5, FIG.
The automatic scoring program PRG5 shown in FIG. The correct answer table describes correct answers and points (for example, one point for the question A and five points for the question B) for each question in the collection of questions.

On the other hand, each client 3 has a computer 31, and a keyboard 32, a liquid crystal display 33 and a magnetic disk 34 are connected to each computer 31.

When the students learn by using the collection of questions using the distance learning system 1 having the above-described configuration, the students are displayed on the liquid crystal display 33 in their own clients 3 according to the following procedure. The learning is advanced by operating the keyboard 32 while viewing the information.

That is, the student arbitrarily selects one of the unanswered / unstarted question course and the priority designated question course.
Here, the unanswered / unstarted course is a course to learn about questions that have been answered before but were incorrect and those that have not yet been started. Regardless of whether or not it is a course in which the student himself / herself wants to repeatedly learn and learns about a problem specified in advance.

First, when the student selects the unanswered / unstarted course, the client 3 transmits the fact to the server 2 via the Internet 5. In response, the computer 21 of the server 2 reads the uncorrected / unstarted problem learning program PRG1 shown in FIG. 2 from the magnetic disk 24, and performs processing based on the uncorrected / unstarted problem learning program PRG1 as described below. Execute.

First, in step S1 of the unanswered / unstarted problem learning program PRG1, in order to determine a method of displaying a question, the liquid crystal display 33 of the client 3 determines whether a learning step is specified, is random, or is sequentially specified from the top. An indication that a three-part alternative is required. Upon seeing this display, the student selects one and sends it to the server 2 via the Internet 5.

Next, step S2 of the uncorrected / unstarted problem learning program PRG1 is entered, and the table of contents of the uncorrected / unstarted problems and the correct answer of all students at the present time of each question are entered according to the result of the three choices. The rate is read from the magnetic disk 24 and transmitted to the client 3 via the Internet 5. In response, the computer 31 of the client 3
As shown in FIG.
The table of contents of the unstarted questions is displayed on the liquid crystal display 33 together with the correct answer rate of all students at the present time of each question. And the unanswered / unstarted problem learning program PRG
In step S3, the student is prompted to select a problem that the student wants to solve. Therefore, the student selects the question while referring to the correct answer rate in real time and infers the degree of difficulty, and transmits the question to the server 2 via the Internet 5. Then, uncorrect answer
In step S4 of the unstarted problem learning program PRG1, the student selects the question selected from the magnetic disk 24, and distributes the question to the client 3 via the Internet 5. In response to this, the computer 3 of the client 3
1 displays the problem received from the server 2 on the liquid crystal display 33.
Display above.

Then, in step S5 of the unanswered / unstarted problem learning program PRG1, the user is prompted to solve the problems on the liquid crystal display 33 and transmit them, and the student solves these problems and sends the answers via the Internet 5. To the server 2.

In response to this, the program enters step S6 of the uncorrected / unstarted problem learning program PRG1, in which a correct answer rate calculation routine is executed in order to obtain the correct answer rate of the students who have solved this problem. To do this, the correct answer rate calculation program PRG4 shown in FIG. 5 is read from the magnetic disk 24, and the current correct answer rate of the problem is calculated based on the correct answer rate calculation program PRG4. That is, in step S1 of the correct answer rate calculation program PRG4, the answer received from the student is written in a memory (not shown) in the computer 21, and in step S2 of the correct answer rate calculation program PRG4,
The correct answer table is read from the magnetic disk 24, and the answer in the memory is compared with the correct answer table to determine whether the answer is correct or incorrect. After that, the correct answer rate calculation program PRG
In step S3 of step 4, the number of correct answers is divided by the total number of answerers to calculate a correct answer rate.
To overwrite. Here, the correct answer rate calculation routine ends.

After the correct answer rate is calculated by the correct answer rate calculation routine in this way, the process enters step S7 of the uncorrected / unstarted problem learning program PRG1, and executes an automatic scoring routine. For this purpose, the automatic scoring program PRG5 shown in FIG. 6 is read from the magnetic disk 24, and scoring is performed based on this automatic scoring program PRG5. That is, in step S1 of the automatic scoring program PRG5, the answer received from the student is written in a memory (not shown) in the computer 21, and in step S2 of the automatic scoring program PRG5, the correct answer table is read from the magnetic disk 24. The answer in the memory is checked against the correct answer table to determine whether the answer is correct or incorrect. After that, the process enters step S3 of the automatic scoring program PRG5, calculates the student's individual score by referring to the score on the correct answer table, and calculates the statistical data such as the average score and the deviation value of all the students, Create a question score table. Finally, the process enters step S4 of the automatic scoring program PRG5, and transmits these data to the client 3 via the Internet 5. In response to this, the computer 31 of the client 3 starts table creation software (application software for creating a table or a graph from some data), creates a table or a graph based on the data received from the server 2, and It is displayed on the display 33. Here, the automatic scoring routine ends.

When the scoring is performed by the automatic scoring routine, an uncorrected / unstarted problem learning program P
In step S8 of RG1, the computer 21 of the server 2 updates the table of contents of the unanswered / unstarted questions. In other words, if the student's answer is correct, there is no need to display this question as an uncorrected / unstarted question from the next time,
Remove this question from the table of unanswered / unanswered questions. Conversely, if the student's answer is incorrect, the table of contents of the unanswered / unstarted question is left unchanged without any change so that this question is displayed as an unanswered question the next time.

Then, the process goes to step S9 of the uncorrected / unstarted problem learning program PRG1 to update personal data and statistical data. At step S10 of the uncorrected / unstarted problem learning program PRG1, a distinction between a correct answer and an incorrect answer is made. The scoring result including the result is transmitted to the client 3 via the Internet 5. In response, the computer 31 of the client 3
The scoring result including the correct answer / incorrect answer received from the server 2 is displayed on the liquid crystal display 33.

Next, step S11 of the unanswered / unstarted problem learning program PRG1 is entered, and a message is displayed on the liquid crystal display 33 asking the student whether to solve the next problem. On the other hand, if the student inputs "No", the learning by the uncorrected / unstarted problem course ends, and if the student inputs "Yes",
The procedure returns to step S2 of the unstarted problem learning program PRG1, and the same procedure is repeated. If you can answer this question correctly, as described above,
Since it has been deleted from the table of contents of the unstarted problems, the uncorrected / unstarted problem learning program PRG1 will be executed for the second and subsequent times.
In step S2, the correctly answered question is not displayed again.

As described above, if the student proceeds along the uncorrected / unstarted problem course, the number of uncorrected / unstarted problems decreases each time the student solves the problem and corrects the answer. You can concentrate on learning only the questions you have not answered correctly (that is, the ones you are not good at) and the ones you have not yet started, so that you can clearly identify the questions that you did not answer correctly and improve your learning outcomes. It becomes possible. In addition, every time you solve a question, you can get the correct answer / incorrect answer for the answer and statistical data instantaneously in real time, so you can prevent the decrease in learning motivation due to the delay in the aggregation of statistical data. It becomes possible.

On the other hand, when the student selects the designated designated problem course, the fact is transmitted from the client 3 to the server 2 via the Internet 5. In response to this, the computer 21 of the server 2 reads the priority designation program PRG2 shown in FIG.
After executing the processing based on the priority designation program PRG2, the priority learning program PRG3 shown in FIG.
The processing based on G3 is executed.

First, in step S1 of the priority designation program PRG2, a correct answer rate calculation routine is executed to calculate a correct answer rate, and then, in step S1 of the priority designation program PRG2.
In step 2, the table of contents for priority designation and the correct answer rate of all students at the present time for each question are read from the magnetic disk 24 and transmitted to the client 3 via the Internet 5. In response, the computer 31 of the client 3
As shown in (b), the table of contents for priority designation received from the server 2 is displayed on the liquid crystal display 33 together with the correct answer rate of all students at the present time of each question. Then, in step S3 of the priority designation program PRG2, the student is prompted to select a problem that the student wants to designate as a priority problem. Therefore, the student selects or cancels the question while inferring the difficulty by referring to the correct answer rate in real time, and transmits the question to the server 2 via the Internet 5. At this time, as shown in FIG. 7B, the number of times of learning is designated by a number such as “1”, “2”, “3” or the like, and the importance is set to “A”, “B”, “C”, etc. It can also be set in stages. Here, the designation of the priority issues is completed, and the table of contents for the priority designation includes only the important issues for the student.

When the designation of the priority question has been completed, the process proceeds to step S1 of the priority learning program PRG3, and the table of contents for the priority designation is displayed on the liquid crystal display 33 of the client 3. At step S2 of the priority learning program PRG3, the lecture is taken. At the same time, the student is prompted to specify the problem, and in step S3 of the priority learning program PRG3, the student is prompted to solve and transmit the problem. Therefore, the student specifies the question, solves the question, and sends the answer to the server 2 via the Internet 5.

Next, the program enters step S4 of the priority learning program PRG3, executes a correct answer rate calculation routine to calculate a correct answer rate, and then executes an automatic scoring routine to score in step S5 of the priority learning program PRG3. Next, the process enters step S6 of the priority learning program PRG3, updates the personal data and statistical data, and transmits the scoring result including the correct answer / incorrect answer to the client 3 via the Internet 5 in step S7 of the priority learning program PRG3. . In response to this, the computer 3 of the client 3
1 displays on the liquid crystal display 33 the scoring result including the correct answer / incorrect answer received from the server 2.

Next, step S8 of the priority learning program PRG3 is entered, and a message asking the student whether to solve the next problem is displayed on the liquid crystal display 33. On the other hand, if the student inputs "No", the learning by the priority designated problem course ends there, and the student enters "Y".
When "es" is input, the process returns to step S2 of the priority learning program PRG3, and the same procedure is repeated.
At this time, each question is displayed for the number of times of learning specified in advance.

As described above, by proceeding with the learning in accordance with the priority designated problem course, the student can concentrate on learning only the important problems selected as the priority problems, so that efficient learning can be achieved. It is possible to do. In addition, every time you solve a single question,
In addition to the incorrect answer, since statistical data is obtained instantaneously in real time, it is possible to prevent a decrease in learning motivation due to a delay in counting of statistical data.

In the above-described embodiment, in the server 2 and each client 3, the keyboards 22, 32 as input devices, the liquid crystal display 23 as output devices,
33, the case where the magnetic disks 24 and 34 are adopted as the storage device has been described.
Input devices other than 32 (for example, pointing device, voice input device, scanner, etc.), output devices other than the liquid crystal displays 23, 33 (for example, CRT display, printer, etc.), or storage devices other than the magnetic disks 24, 34 (for example, , Optical disks, magneto-optical disks,
Semiconductor memory) can also be used.

In the above embodiment, the case where the Internet 5 is used as a communication network connecting the server 2 and each client 3 has been described, but a network using a dedicated line for personal computer communication, an intranet, or the like is used as this communication network. It does not matter.

[0041]

As described above, according to the first aspect of the present invention, each time a student solves a problem and corrects it, the number of uncorrected / unstarted problems is reduced. You can concentrate on learning only the questions you have not answered correctly and have not yet started, and at the same time, every time you solve a single question,
In addition to incorrect answers, statistical data can be obtained instantaneously in real time, so problems that you could not answer correctly can be clearly separated from correct answers, improving learning outcomes, and obtaining statistical data in real time Therefore, it is possible to provide a distance learning system in which a desire to learn is maintained.

According to the second aspect of the present invention, the student can concentrate on only the important questions selected as the priority questions, and at the same time,
