Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a system for educating mutually related knowledge, such as educating plant operating procedures.

[0002]

2. Description of the Related Art A conventional method for evaluating a learner's understanding situation in an education system is, for example, whether or not the knowledge is known for each piece of knowledge, such as the device disclosed in Japanese Patent Laid-Open No. 58-11985. Or, the main method was to record how many questions were answered correctly.

[0003]

However, there is a problem that, as in the above-mentioned prior art, evaluating the understanding situation for each piece of knowledge is not sufficient to evaluate the understanding situation of mutually related knowledge. It was There is also a problem that it is difficult for learners and educators to grasp the understanding status of related knowledge other than the evaluated knowledge.

An object of the present invention is to more accurately evaluate a learner's understanding situation by using the understanding situation of knowledge related to the knowledge when evaluating the understanding situation of a certain knowledge, and to evaluate the evaluation result and the relation. The purpose is to promote the understanding of learners by showing the understanding status of knowledge to learners and educators and giving guidance based on it.

[0005]

SUMMARY OF THE INVENTION The present invention has means for obtaining the relevant knowledge of the knowledge for evaluating the understanding situation from the data in advance by previously storing the data of the mutual relation of each knowledge to be taught, and the related knowledge. It provides a means to evaluate the learner's understanding situation using the understanding situation and a means to display the understanding result of this evaluation result and related knowledge and a message based on it to the learner and the educator. is there.

[0006]

In the present invention, when the learner's understanding situation is evaluated, the learner's understanding situation is evaluated by using the knowledge understanding situation around the knowledge to be evaluated. Then, the evaluation result, the understanding status of the related knowledge, and a message based on the understanding status are displayed to the learner and the educator.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to FIGS. 1, 2, 3, 4, 5, and 6. FIG. 1 shows the basic configuration of this system. In this system, when the understanding situation is evaluated, first, the related knowledge of the knowledge to be evaluated is identified by using the related knowledge identifying function 4 by using the data 3 of the mutual relation of the educational knowledge. After that, the past learning history of the knowledge to be evaluated and the understanding situation data of the related knowledge are extracted from the learner model 2, and the understanding situation of the knowledge to be evaluated is evaluated using the understanding situation evaluation function 1. After that, based on the judgment result and the data in the memory 6, the teaching information display function 5 is used to display various teaching data and messages to the learner and the educator.

An embodiment relating to a system for teaching the operating procedure of a nuclear power plant will be described in detail below. Each piece of knowledge to be taught is set in advance on a function hierarchy model as shown in FIG. 2, which hierarchically represents the functions of the plant. Basically, on each node of this functional hierarchy model, a quantitative value (0 to 100) representing a learning history and an understanding situation of a learner regarding the node is recorded. It also displays to the learners and educators that "This system considers the understanding status of related knowledge when evaluating the understanding status."

FIG. 3 shows a flowchart for specifically evaluating the understanding situation. The understanding situation is basically evaluated when a learning history is newly recorded in the node. First, as a basic evaluation index, the past history of the node is examined, and the correct answer rate (0 to 100) is calculated by the following equation.

[0010]

[Equation 1]

Next, the functional hierarchy model is examined, and the nodes that are connected to the node of the knowledge to be evaluated and above and below are identified as related knowledge. Then, as shown in FIG. 4, the average value of the quantitative values representing the understanding status of the nodes of the related knowledge is obtained, and the value of the weighting coefficient to be applied to the above-mentioned correct answer rate by the correctness of the value and the latest learning history is shown in Table 1. To decide.

[0012]

[Table 1]

The coefficient in Table 1 is an example set in consideration of the effect that if the understanding level of the related knowledge is high, the decrease in the value indicating the understanding level can be suppressed even if the answer is incorrect. The understanding situation of the knowledge to be finally evaluated is expressed as the above-mentioned correct answer rate multiplied by the coefficient obtained from Table 1. At this time, if the quantitative value indicating the understanding situation exceeds 100, it is uniformly 10
Set to 0. In addition, a message obtained by using Table 2 from the quantitative value evaluated after the evaluation, the understanding status of the related knowledge, the related knowledge used, the understanding status of the knowledge to be evaluated and the understanding status of the related knowledge is given to the learner, for example, “decompression”. Your understanding of cooling is 68. Related knowledge is reactor pressure control, water injection system, depressurization system, RHR.The understanding of related knowledge is 81. It seems that related knowledge is well understood. Are you thinking about decompression cooling and making a mistake? "Is displayed.

[0014]

[Table 2]

As an alternative, the case of using a table such as Table 3 showing the mutual relationship of the knowledge to be taught, instead of the function hierarchy model, for identifying the related knowledge will be described.

[0016]

[Table 3]

The values in Table 3 show the relevance of knowledge between 0 and 1
00, and the larger this value is, the higher the relevance is determined. When identifying related knowledge using this table, set how much related knowledge is used (for example, 5
0), knowledge having a value greater than or equal to this value is determined to be related knowledge. In addition, from the one with the largest value in Table 3, for example,
It is also possible to judge three as related knowledge, use this value itself for weighting in understanding situation evaluation, and display this value itself to learners and educators.

Further, as the basic evaluation index, not only the correct answer rate is used, but the values in Table 1 are set as shown in Table 4 in consideration of the types of errors made by the learner in the latest learning history. It is conceivable to perform weighting such as setting or not considering the learning history that has become older than a certain level (for example, determination is made using only the latest 10 history).

[0019]

[Table 4]

Further, there is also a method in which the degree of importance for each history is used instead of the correct answer rate, and the value obtained by the following equation is used as the basic value for the understanding situation determination.

[0021]

[Equation 2]

As an example of confirming the effectiveness of the understanding situation evaluation method using the related knowledge, the result of evaluating the understanding situation of the learner using the above-mentioned method is quantified from 0 to 100 on each node of the functional hierarchy model. About what was expressed using
FIG. 5 shows a processing result using the understanding state of the related knowledge, and FIG. 6 shows a processing result when the processing result of the related knowledge is not used. As an example of the learner used at this time, it is assumed that the learner has a low understanding of the decompression meter and the hydrogen concentration system and a high understanding of the RHR system. As a result, it was found that this method evaluated the learner's understanding situation appropriately. It was also found that this method has the following effects.

(A) If there are good or bad comprehension situations, they are emphasized. Depending on the method of setting the coefficient at the time of evaluation of comprehension situation, the comprehension situation of related knowledge is an average value (eg, 50). The better the better, the better the understanding, and the worse the average, the worse the understanding. As a result, learners will be given more emphasis on what is good and what is weak.

(B) Smoothing local fluctuations in understanding situation When considering the understanding situation of related knowledge, if the understanding situation of related knowledge is bad, the understanding situation of the node that calculates the understanding situation is more extreme than the surroundings. I don't think it will improve. This also applies when the relevant knowledge is well understood. Therefore, nodes with local fluctuation values do not appear as a whole, and the change in the distribution of the overall understanding situation becomes smooth.

When comparing FIG. 5 and FIG. 6 concretely, for example,
In the RHR related node, the comprehension level of the related node is 80, 100, 70, 60, 100, 90, 80 in FIG. 6, whereas it is 90, 100, 80, 70, 100, in FIG.
It is 100 and 90, and it can be seen that the effect (a) is obtained. Also, focusing on the node of “reactivity control”, in FIG. 6, the understanding level of “SLC” connected downward is about 100 and the understanding level of “maintaining subcritical” connected upward is about 80. On the other hand, the degree of understanding of “reactivity control” is 70, but in FIG. 5, it is 100 and 9 respectively.
It is 0,90. Therefore, it is understood that the above-mentioned effect (b) is exhibited.

[0026]

According to the present invention, the understanding situation of the learner can be accurately evaluated by considering the understanding situation of the knowledge related to the knowledge for evaluating the understanding situation. Guidance information using evaluation results and the understanding of related knowledge will be easier to understand. Furthermore, by showing the teaching information to the learner and the educator, the learner and the educator can appropriately judge the understanding status of the learner. In addition, this effect promotes the understanding of learners.
