Description

[Detailed description of the invention] The present invention relates to a reaction analysis device, which is easy to operate by displaying analysis information of response data and feedback information from teachers to respondents on a monitor in the form of video signals. It is an object of the present invention to provide a reaction analysis device capable of displaying analysis information, feedback information, and teaching materials on a monitor, each alone or in combination, and having a high educational effect.

Traditionally, in group education, etc., a teacher operates a video tape recorder to display the recorded teaching material on a television monitor, and multiple learners operate their own answering devices to respond to this teaching material. I have something to do. Conventional reaction analysis devices for educational equipment such as this aggregate information from each answering device, perform calculations, and display the information on a response distribution display panel that is separate from the television monitor. The correct answer numbers for the above-mentioned teaching materials were displayed on the provided lamps to provide feedback to the learners. For this reason, the teacher must operate the video tape recorder and the reaction analysis device separately in order to proceed with the learning, and this operation is complicated. In addition, learners can use a television monitor,
The disadvantage was that the lamp on the answering device and the answer distribution display panel had to be looked at one after another, reducing the educational effect.

The present invention eliminates the above-mentioned drawbacks, and an embodiment thereof will be described below with reference to the drawings.

The figure shows a block system diagram of one embodiment of the reaction analysis apparatus according to the present invention. In the figure, 1 is an input terminal to which a video signal of a teaching material from a video tape recorder or the like (not shown) is input, and 2a to 2x are input terminals to which response information from answering devices is input. The video signal from the input terminal 1 is supplied to the terminal 3a of the switch circuit 3 and the synchronizing signal separation circuit 4. A synchronization signal separation circuit 4 separates a vertical synchronization signal, a horizontal synchronization signal, and a color burst signal from the supplied video signal, and supplies these to a determination circuit 5 and a synchronization signal generator 6. The judgment circuit 5 integrates the vertical synchronization signal among the supplied signals, and when this integrated value exceeds a certain level, it becomes a high level, and when no video signal enters the input terminal 1 and the integrated value is less than a certain level, it becomes a low level. A signal is generated and is supplied to the control input terminal of the switch circuit 3. In addition, the synchronization signal generator 6 divides the constant frequency signal generated by the built-in oscillator to generate a vertical synchronization signal, a horizontal synchronization signal, and a color burst signal, and a video signal is input from the input terminal 1. In this case, the vertical synchronization signal, horizontal synchronization signal, and color burst signal are generated in synchronization with the three signals from the synchronization signal separation circuit 4, and these are supplied to the video signal generator 7 and the feedback video signal generator 8. .

Further, the response information from the input terminals 2a to 2x is supplied to the arithmetic circuit 9. Here, when each answering device (not shown) has, for example, five answer selection buttons, there are six types of answer information including unanswered buttons, and the arithmetic circuit 9 has multiple answering buttons. The answer information for each answer selection button is aggregated for each answer selection button, the ratio for each answer selection button is calculated, and this analysis information is supplied to the video signal generator 7. The video signal generator 7 supplies the signal from the synchronization signal generator 6 to the black burst signal generator 11, and as shown in FIG.
~ "5", the letters "R (R represents unanswered)",
The numbers, ruled lines, and the ratio of each answer selection button from the calculation circuit 9 ("0.15", "0.20", "0.10" in the ruled lines,
A video signal for superimposing the numbers "0.05,""0.50," and "0.00" is generated, and this video signal is supplied to the mixer 12 and the video signal switching circuit 13.
The black burst signal generator 11 generates a black burst signal representing a black image signal from the supplied vertical synchronizing signal, horizontal synchronizing signal, and color burst signal, and supplies this to the terminal 3b of the switch circuit 3.

Here, the switch circuit 3 outputs a video signal from the terminal 3a when the control signal from the determination circuit 5 is at a high level, outputs a black burst signal from the terminal 3b when it is at a low level, and mixes this output signal. 12 and a video signal switching circuit 13.

The operating device 14 is operated by the operator (teacher) to generate an instruction signal for displaying a mark indicating "answering" and a mark indicating the correct answer number, which are feedback information from the teacher to the respondent. The signal is supplied to the feedback video signal generator 8, and a switching instruction signal is supplied to the video signal switching circuit 13 for switching its output signal. When the instruction signal indicates "answering", the feedback video signal generator 8 generates a video signal that displays the mark a on the screen shown in FIG. 2 in yellow, for example, based on the signal from the synchronization signal generator 6. However, when the instruction signal indicates, for example, that "No. 2" is the correct answer, a video signal that displays mark b (feedback to the answerer) is generated and supplied to the mixer 12. The mixer 12 inserts the super display shown in FIG. supply The video signal switching circuit 13 outputs a video signal mixed with the teaching material from the mixer 12 and the analysis information and feedback information of the answer data, a video signal of the teaching material from the switch circuit 3, and a video signal from the video signal generator 7 according to the switching instruction signal. One of the video signals of analysis information is taken out and supplied to a television monitor (not shown) via an output terminal 15.

Therefore, the teacher can easily display teaching materials and/or analysis information and feedback information on the television monitor simply by operating the operating device 14.

As mentioned above, the reaction analysis device of the present invention includes a generation means for generating an analysis video signal to be displayed on a television screen from information obtained by aggregating and analyzing response data from a plurality of response devices, and an operation generating means for generating a mark video signal for displaying a predetermined mark on a screen for feedback from the respondent to the respondent; mixing means for mixing at least the analysis video signal and the mark video signal; and at least the analysis video signal and the mark video signal. Since the switching means is supplied with the video signal from the mixing means and switches and outputs one of the video signals, analysis information and feedback information of the response data can be displayed on the television monitor. mixes the video signal of the teaching material presented to the respondent, the analysis video signal, and the mark video signal, and the switching means is supplied with the video signal of the teaching material, so the teacher operates one operating device. Analytical information of response data, feedback information, and teaching materials can be easily displayed on the television monitor by simply using the television monitor 1.
It has the advantage that all you have to do is look at the information, and the educational effect is high.
