Generally, the learner solves the problem of the diagnostic test, and the educator can score the learner's answer and diagnose the learner through the learner's score. Recently, as the use of smart devices such as smart phones or tablet PCs is increasing, the utilization of smart pens as input means for inputting on the touch screen of smart devices is increasing, and an environment for learning by utilizing smart pens is being developed .

Various embodiments will be described in detail with reference to the accompanying drawings. Wherever possible, the same reference numbers will be used throughout the drawings to refer to the same or like parts. References made to specific examples and implementations are for illustrative purposes only, and are not intended to limit the scope of the invention or the claims.

Whenever an element is referred to as being "comprising" another element in the description of the invention or claim, it is not to be construed as being limited to only that element, It should be understood that it can be done.

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

1 is a schematic of a system for performing a diagnostic test in accordance with an embodiment of the present invention. The learner can solve at least one problem presented for the diagnostic test and derive the answer. The learner may use the smartpen 10 as a pencil or pen to write on the printed matter 20 such as a diagnostic test paper to solve at least one problem. A learner using the smart pen 10 may be referred to as a " user " hereinafter.

The printed matter 20 is not a general paper but a pattern such as a dot pattern is formed so that the information input by the smart pen 10 can be recognized. .

It is preferable that the problem for the diagnostic test presented in the printed matter 20 is not a problem that can be solved by simple memorization. That is, it is desirable to set up a strategy for problem solving and describe the solution process so that the conclusion can be drawn. For example, a type of problem with a narrow selection of strategies, such as an operation, can be easily used for data analysis for a learner's diagnosis. However, if the problem is too easy compared to the level of the learner, it may not be desirable because the learner may draw the answer as soon as he or she sees it without using the smartpen. In addition, the answer to the question can be easier to analyze the data than if it is a multiple choice, and because the response of the narrative type can be an answer according to the way of expressing the student even if it is a questionable answer, .

The smart pen 10 may include a camera (not shown) to recognize a pattern input to the printed matter 20 and may include a local communication module (not shown) to transmit data to the diagnostic testing device 30 You may. In this way, it may be possible to transmit data from the smart pen 10 in a streaming manner in real time. It is necessary to confirm whether or not the battery is fully charged sufficiently (90% or more) before use, and to confirm whether or not data is normally transmitted from the smart pen 10 before the use of the smart pen 10.

When the learner solves at least one problem of the printed matter 20 by using the smart pen 10, the diagnostic test apparatus 30 for diagnosing the learner performs a method 200 for performing the diagnostic test shown in Fig. 2 ).

Specifically, the diagnostic test apparatus 30 may include a memory 31 and a processor 32. [ Each step of the diagnostic test method shown in Fig. 2 may be performed by the processor 32 and a plurality of pieces of information such as, for example, data for a diagnostic test and diagnostic test result data may be stored in a memory (31). The diagnostic test apparatus 30 may be, for example, a mobile device (e.g., tablet PC) or a computer paired with the smartpen 10, and may be connected to a server or used as a server. It is well known to those skilled in the art that the components of the diagnostic test apparatus 30 are not all shown and may include, for example, a communication module, a user interface, a display unit, and the like.

Alternatively, the method of the diagnostic test shown in Fig. 2 may be performed by a computer or a processor, by a computer program stored in the medium. That is, the computer program stored in the medium may include instructions for causing a computer or a processor to perform each step of the diagnostic test method shown in Fig.

Referring to FIG. 2, a method 200 of a diagnostic test using a smart pen will be described in detail.

First, the user can input information such as solving a problem with a smart pen on a printed matter for at least one problem presented for a diagnostic test. Thereafter, the diagnostic test apparatus may perform a step of acquiring pen data of the smart pen based on the information input by the smart pen (S201).

The step of acquiring the pen data of the smart pen may include identifying a page that the user has entered with the smartpen, and may include forming a plurality of strokes input at the page, each stroke of the plurality of strokes The coordinate values of the points, the time information in which the points are entered, and the pressure of the points.

Illustratively, referring to FIG. 3, there is shown pen data that can be obtained from the smartpen. A plurality of strokes (stroke 1, stroke 2, stroke 3, ... stroke N) within a specific page that the user has entered with the smartpen can be identified. For example, one stroke can be specified as a continuous trajectory from the pen down point to the pen up point of the smart pen, and the pen point from the pen point down to the writing stop point, The coordinates up to the point may be recorded at specific time intervals (e.g. 0.012 to 0.015 seconds in FIG. 3). Accordingly, the pen data including the XY coordinate value of the points forming the stroke, the time information of the corresponding points, the pressure of the corresponding points, and the like can be identified for each stroke. As an example shown in FIG. 3, for stroke 1 among a plurality of strokes of a specific page, the first point is (051.94, 053.70) and the pressure is 070 and the time at which the point is input is 2017 It can confirm that it is 11:13 and 52.624 seconds on October 26, That is, in this manner, the number of total strokes and detailed data of each stroke can be extracted for each individual page.

Next, the diagnostic testing device may perform the step of generating analysis information related to the at least one problem of the smartpen user from the obtained pen data (S202). An example of the analysis information that the diagnostic testing device can generate from the obtained pen data is shown in Figure 4 and this analysis information can be generated for each problem in connection with the at least one problem, Age, gender, and the like. ≪ RTI ID = 0.0 > The analysis information that can be generated by the diagnostic test apparatus is not limited to those illustrated in FIG. The analysis information will be described in more detail below.

In order to generate analysis information related to the user's at least one problem, the diagnostic testing device may calculate a total stroke of strokes that can be extracted from the pen data, and the total time Total time can be calculated. The meaning of the total time of using the smartpen by the user in relation to the at least one problem is determined by the user's intro time reading the problem after the at least one problem is presented, And may include a solving time for solving the problem. Therefore, the diagnostic test apparatus may calculate the time (Intro time) when the user reads the problem and the time that the user actually solved the problem (solving time). For this purpose, for example, the diagnostic test apparatus may calculate the time between the pen-up point of the last stroke of the previous problem and the pen-down point of the first stroke of the next problem, time.

More specifically, in order to generate analysis information related to the at least one problem of the user, the diagnostic testing apparatus tracks the coordinates of the points forming each stroke so that the coordinate values of the points are substantially constant , It can be determined that a delay has occurred. The diagnostic test device may also calculate a Delay time and a Number of Delays of the delay generated for the user for the at least one problem. The predetermined time may be, for example, 1 second, 2 seconds, 3 seconds, 4 seconds, 5 seconds, or the like, and the weight may be added to the delay differently as the predetermined time is longer. Accordingly, the number of times of delay and the total time based on, for example, 1 second, 2 seconds, 3 seconds, 4 seconds, and 5 seconds may be calculated.

In addition, the diagnostic test apparatus may further include analysis information related to the at least one problem of the user, which is not illustrated in FIG. 4, but includes a stroke velocity (cm / second) In this paper, we propose a new method to solve the problem by solving velocity, strokes / time, stroke length, area of the area used for the solution, entropy, out of order, the time before the next problem starts (Out of order time), and so on. have.

For example, the area of the area used for the progress of the pool may be calculated as the area of the area where the stroke exists. The complexity (Entropy) in the direction of solving determines that the stroke from the left to the right or from the top to the bottom is low, while the stroke from the right to the left, or from the bottom to the top, It can be determined that the entropy is high and can be calculated. With regard to the cross out, there is a typo cross out, a problem solving cross out, a big cross in which the whole or equivalent area is erased out). The problem attempted can be calculated as the number of times that the problem has stayed for more than a certain period of time and the number of times the order of the problem solving is changed (Out of order) ≪ / RTI >

When the diagnostic test apparatus generates analysis information related to the at least one problem of the smartpen user, the diagnostic test apparatus can perform a step of determining a behavior pattern of the user based on the generated analysis information (S203 ).

The diagnostic testing device may generate analysis information of a plurality of users associated with the at least one problem and store the analysis information in a memory. Alternatively, the diagnostic testing device may generate analysis information of a plurality of users associated with the at least one problem and may transmit the analysis information of the plurality of users associated with the at least one problem to a separate server, . Such transmission and reception can be performed in real time, and the stored analysis information may be periodically updated. The diagnostic testing device may then compare the analysis information already stored in association with the at least one problem to the analysis information generated for the user. Educators who want to perform a diagnostic test may accumulate analysis information for a plurality of users, i.e., students, related to problems of the diagnostic test by sharing the at least one problem on a network.

In addition, the diagnostic testing apparatus may further include a processor that, when comparing the analytical information already stored in association with the at least one problem and the analytical information generated for the user, processes the analytical information generated based on the correlation between the at least one problem You may. For example, for a user with analytical information that differs significantly from pre-stored analytical information for particular problems with high degrees of correlation, the behavior pattern for that type of problem solving may be more noticeable.

5 is a diagram showing a result of a diagnostic test, for example, showing a detailed area of a report card. 'Question' is the score of the problem, 'Total Score' is the total score of the problem 'OX', 'Concept Score' is the total score of the problem, 'Unit' is the number of the problem, 'Unit' , 'Process Score', 'Process Score', 'Process Score', 'Score', 'Score', and 'Process Score' , And 'Correct Rate' is the percentage of correct answer. 'Understanding' indicates that the behavior pattern related to the user 's problem is higher than the behavior pattern of the user who derives the correct answer according to the analysis information analyzed through the pen data. For example, although the correct answers were met, the number of 'Understanding' users was low when users were worried about many hours or wrong answers,

As shown in the diagnostic information data of FIG. 5, for example, the diagnostic test apparatus includes analysis information of a plurality of users related to the first problem, total number of strokes (N strokes) The average values of a plurality of users of Solving time, Delay time and Number of Delays / N of Delays of the first problem, The total number of strokes, the solving time, the total delay time, and the number of delays, respectively. By way of example, while the average time of solving a problem of a plurality of users associated with the first problem (Q1) of FIG. 5, the total number of strokes, and the number of delays is 44.4, 124.2, 89.3, 15.3, respectively, Since the time, the delay time, the total number of strokes and the number of delays are 44.0, 21.2, 88.0, and 7.0, respectively, which solve the problem related to the first problem (Q1) of the user, The behavior pattern may be determined in consideration of the fact that it shows a very low value.

That is, the diagnostic test apparatus can determine and display a behavior pattern of a specific user based on the contrast result. In this regard, FIG. 6 exemplarily shows a behavior pattern of the user determined based on the analysis information generated based on the total number of strokes and the number of delays (Number of Delays).

First, in the case of a user who has been analyzed to have a relatively large number of strokes, a small number of delays and a short delay time, for example based on a predetermined criterion of the analysis information, We can think about entropy as a function of the entropy of a user with a high entropy, and the user's behavior pattern with a low entropy is " It can be decided to "record it carefully".

Second, in the case of a user who has been analyzed to have an average number of strokes, an average number of delays, and an average delay time, the diagnostic tester will take into account the detailed numbers of the information, You may decide that you need to re-check after 2 to 3 weeks, "or" You need to practice at a normal level. "

Third, for the number of strokes, the number of delays, and the user's behavior pattern analyzed as having a long delay time, the diagnostic testing device may determine that it is "not known".

Fourthly, for a small number of strokes, a small number of delays, and a user's behavior pattern that has been analyzed to have a long delay time, the diagnostic tester can determine " And the behavior pattern of the user analyzed as having a small number of delays and a short delay time, the diagnostic test apparatus can determine that it is "very familiar with the item".

Finally, for a user with a small number of strokes and a very short delay, it can be determined that " iterative checking is in progress during the solving process ".

The diagnostic result of the behavior pattern of the user determined as shown in FIG. 6 may be displayed in the behavior pattern of the behavior pattern shown in FIG. This allows users to analyze the behavior patterns seen in the course of problem solving and to find out the cause of such behavior, as well as to evaluate users by simply relying on whether the answer to the question is correct or incorrect, Teaching can be possible. For example, when a very long delay occurs over a certain period of time in the user's problem solving process, the color of the stroke is displayed differently or the delay time is tagged in the area of the stroke, Can be expressed more visually. In this way, educators may devise more effective pedagogues for learners.
