Description

  The present invention targets a server client environment with a plurality of PCs in a network environment, the server grasps the learning situation of each of a large number of students, and the teacher grasps the learning situation of the student through the server and adapts it. The present invention relates to an information distribution system for improving learning efficiency by generating and selecting content.

  The mainstream e-learning service currently in use is a web-based learning method (Web Based Training (WBT)). In recent years when broadband is spreading, not only text-based WBT but also WBT incorporating video and audio are increasing, and the content for learning has been enriched. In such a situation, it is necessary for the user to select the content necessary for him / herself.

  The mainstream of e-learning is e-learning (asynchronous education type e-learning) for asynchronous education represented by web-based learning, and synchronous education represented by foreign language education using TV phone, ASP, etc. E-learning (synchronous education-type e-learning). All of them support education centered on users, and the benefits are great in that they can receive education in the time zone and place that the user desires without going to the site to receive education. However, content for learning is not created for each user, but the transition in the content changes according to the user's problem-solving situation. Therefore, the information obtained by the user is only the information described in the content, and if the problem cannot be solved there, the student himself / herself needs to search for the content including the solution by another route. In addition, there is an advantage in that synchronous education by individuals or groups can be received remotely, but since individuals are synchronous education by one-to-one correspondence, a large number of teachers and tutors are required. On the other hand, in many cases, the level is determined by an examination or the like, and the grouping is performed based on the result, so that the group is a group for synchronous education. However, in that case, the group is formed only by the exam, and does not reflect the detailed learning situation and level of the individual, or the career plan in a macro sense, and the education adapted to the individual is performed perfectly. It's hard to say. The technology to solve these problems is to generate learning content that adapts to the learning situation of each student using videos of lessons, etc., and further to grasp the learning situation of each of a large number of learners An information distribution system that aims to perform tutoring frequently has been proposed. (For example, see Patent Document 1)

<Description of processing flow of content creation unit>
Next, processing of the content creation unit in the personal adaptive content generation processing will be described with reference to FIGS.
FIG. 6 is a block diagram showing content creation processing by a teacher. The teacher activates the personal adaptive content generation support system 1030204 on the teacher terminal (S1001), and determines the format of the question sentence and the answer candidate (S1002). Select one of the selection formula and description formula. Next, when the teacher inputs the question sentence and the answer candidate in the input box (303 in FIG. 13) for inputting the arranged question sentence and the answer candidate, a question data set is generated for each question (S1003). ). The question data set includes question number, question content (question sentence and answer candidate value), correct answer value, question format number data (here, 1 if the question format is a selection formula, 2 if the question format is a description formula) Stored). Next, the problem data set generated in S1003 is transmitted to the education information management server (S1004). Next, the content automatic creation module 102209 is activated on the educational information management server. The question number and question content (question sentence and answer candidate value) read from the question data set are embedded in a content format prepared in advance. The content format is configured as shown in FIG. 7, for example. First, a button set of answer start buttons and answer end buttons is arranged below each question number. Place the same number of button sets as the number of problem data sets.
When the answer start button is pressed, accumulation of input events input by the student is started, and input events input by the student are accumulated until the answer end button is pressed. The answer number read from the question data set is assigned to each answer start button and answer end button.

In this way, in the present application, the question start button data is inserted so that the question start button is displayed at a position between the question number of each question and the data of the first question sentence, and the answer to the question above. The question end button data is inserted so that the question end button is displayed after the candidate value. As a result, mouse event information extracted during learning from student input information,
Content capable of acquiring learning history such as keyboard stroke information and trajectory event information with a digital pen can be generated.
Next, a text box for reading the question sentence is arranged between the answer start button and the answer end button. Further, a text box or a radio button for reading answer candidate values is arranged. When the question format is a descriptive formula, a text box is arranged as a means for inputting the answer value. When the question format is a selection formula, radio buttons and text boxes for reading answer candidate values are arranged in parallel for the number of answer candidates as means for selecting answer candidates. Although radio buttons and text boxes are used here, the present invention is not limited to this.
When the answer end button is pressed, the accumulation of input events ends. An answer complete button is located at the end of the format. When the answer completion button is pressed, the answers to all the questions are finished, and the log data of the input event input by the student is transmitted to the education information management server (S1005). With the above processing, the content generation processing ends (S1006).
FIG. 8 is a block diagram showing student answer log data acquisition processing.
The student activates the supplementary content use program 1040202 on the student terminal (S1007), and receives supplementary content from the educational information management server (S1008). The supplementary content usage program 1040202 includes a content usage program and a log extraction program, and the log extraction program functions by starting the content usage program.

Next, the student presses the answer start button for each question and starts answering the question (S1009). Accumulation of input events with the mouse, keyboard, and digital pen is started and input events are accumulated until the answer end button is pressed (S1010).
For example, when answering the selection type question of question 1, processing for selecting a radio button with the mouse occurs. When the radio button 1 is selected by the log extraction program, a relative time log from when the answer start button is pressed, a time stamp log, and an answer log indicating that the radio button 1 is selected as a mouse event are acquired. Each time a student selects a radio button, a log is acquired and saved as answer history data.

Further, for example, when answering the description type problem of question 2, processing for inputting into a text box with a keyboard occurs. The log extraction program obtains an answer log every time an input is made in the text box as a relative time log after the answer start button is pressed, a time stamp log, and a key event, and saves it as answer history data . For example, when “Yes” is entered in a text box as a key event, log data with an answer value of “Yes” is accumulated. When “Yes” existing in the text box is deleted with the Delete key, log data indicating that “Yes” has been deleted is accumulated (S1011).
Next, the student presses the answer end button for each question to finish answering the question (S1012).
By depressing the answer end button, the accumulation of input events with the mouse, keyboard, and digital pen is ended (S1013). Next, when all the questions have been answered and the answer completion button is pressed (S1014), log data (answer data) of the input event is transmitted to the education information management server (S1015).

FIG. 9 is a block diagram showing answer log data analysis processing.
The educational information management server starts the personal feature amount analysis program 102208 (S1016),
The log data of the input event transmitted from the student terminal is analyzed (S1017). Next, the analyzed log data is stored as an event data set. Event data set is user number, answer data set for each question (answer time, number of answers, all entered answer values, final answer value, correct answer value, difference between standard time and actual answer time, digital pen trajectory) (S1018). The stored event data set is used when the teacher activates the personal adaptive content generation support system 1030204 on the teacher terminal and browses the problem answer status data for each student (S1019). The method for viewing the student's problem-solving status will be described later in detail.

<Explanation on personal adaptive content generation processing>
Next, a personal adaptive content generation process by a teacher will be described with reference to FIG. FIG. 10 is a functional block diagram illustrating the personal adaptive content generation processing in units of main functions.
First, the personal adaptive content generation support system is activated on the teacher terminal (103 in FIG. 1) (S2001). Next, the review question answer history of each group and individual student is confirmed (S2002). At this time, the teacher can browse the answer status data analysis result data group of the student in consideration of the review question set, the question number unit, and the feature amount by designating the feature amount as a grouping source. . Also, the review question answer status data and analysis results of the student stored in the education information management server 102 can be browsed for each student, review question set, and question number unit. Next, a group that needs to be associated and an individual student are selected and a new group is created (S2003). Next, a review question for answering the student is created (S2004). At this time, a problem type can be selected from a three-choice problem and a description problem. Next, supplementary content corresponding to the review problem is created (S2005). Extraction and association of the video portion corresponding to the review problem is performed from the selected original video content. Next, supplementary content is transmitted to the group created in S2003 (S2006).
