SUMMARY OF INVENTION

Technical Problem

In a case where students reproduce a learning digital content to learn, educator side who educates the students need to figure out and control progress statuses of learning.

In a system in which the learning digital content is electronic books based on DAISY standard, and the students reproduce the electronic books to cause terminals to read out the electronic books, there is a case where target students may have a difficulty in reading. In such a case, there is a problem that comprehension levels and achievement levels are significantly different depending on students who have difficulty in reading, so that adequate assessments for individual students are difficult for the educator side.

Solution to Problem

Accordingly, in order to solve the above-described problem, it is an object of the present invention to provide an education support system that allows educators to conduct adequate assessments considering handicaps or characteristics of individual students and to offer effective and efficient learning.

An education support system of the present invention includes: one or more terminal devices including a terminal display unit that displays text data of a digital content including text data and voice data created by reading out the text data, a voice output unit that outputs the voice data of the digital content by voice, a reproduction log data memory unit that memorizes at least ID information on phrases of the digital content reproduced by the terminal display unit and the voice output unit and reproduction start times of the phrases for each of the phrases as reproduction log data, and a transmission unit configured to transmit the reproduction log data memorized in the reproduction log data memory unit; and a server device including: a digital content memory unit in which one or more digital content to be distributed to each of the terminal devices are memorized, a receiver unit that receives the reproduction log data transmitted from each of the terminal devices, a data conversion unit that converts the reproduction log data of each of the terminal devices received by the receiver unit into times spent on reproduction and numbers of times of reproduction by phrase of the digital content, a server display unit that displays the times spent on reproduction and numbers of times of reproduction by phrase of the digital content converted by the data conversion unit, and a display control unit that causes the server display unit to display a plurality of sets of times spent on reproduction and numbers of times of reproduction by phrase at different time and date on the same terminal device for the same digital content simultaneously on the same screen.

By employing this configuration, the reproduction log data of the digital content reproduced by the terminal devices is accumulated in the server device, and states of reproduction of the same digital content by the same person at different time and date may be displayed on one screen, so that medium term or long term tutorship and support for comprehension levels and achievement levels of students are achieved.

Also, the display control unit may be configured to arrange strings of the phrases in the respective digital content in a vertical direction, indicate times spent on reproduction of the strings of the phrases by a lateral length of squares arranged on a right side of the respective strings arranged in the vertical direction, and control the lateral length of the squares to be displayed by different colors for each of reproduction times and dates.

In this configuration, comprehension levels and achievement levels of target students may be easily figured out visually along with reproduction times and dates.

Also, the display control unit may be configured to control display so as to allow discrimination between reproduction with a voice output and reproduction without the voice output when indicating the times spent on reproduction of the strings of the phrases by the lateral length of the squares shown on the right side of the respective strings arranged in the vertical direction.

Generally, in a case where time spent on reproduction with the voice output is not much different from time spent on reproduction without the voice output, the comprehension level and achievement level of the corresponding student are considered to have been improved. By employing the configuration described above, comprehension levels and achievement levels of the students may be figured out easily from an overall consideration about presence or absence of the voice output and the time spent on reproduction.

By employing the configuration described above, the students can figure out their own comprehension levels and achievement levels in a medium term or long term learning.

Advantageous Effects of Invention

According to the present invention, an education support system and a terminal device capable of achieving medium term or long term tutorship and support for comprehension levels and achievement levels of students are provided.

DESCRIPTION OF EMBODIMENTS

A general configuration of the education support system according to the present invention is illustrated inFIG. 1.

An education support system20includes one or more server devices30and one or more terminal devices40. InFIG. 1, a state in which a plurality of the terminal devices40are connected to one server device30via a network21such as the internet is illustrated.

The education support system20is a system in which individual students have at least one terminal device40, and the respective students download a learning digital content from the server device30to the respective terminal devices40, and view and listen to the learning digital content. As the learning digital content, electronic books based on DAISY standard are employed. The student operates the terminal device40and reproduce the learning digital content, so that text parts of the learning digital content are displayed on the terminal device, and the terminal device operates to read out voice data corresponding to the displayed text parts.

The server device30is configured to allow educators or teachers of the students, that is, persons who are in charge of managing the student to operate.

The terminal device40will be described based onFIG. 2illustrating a configuration of the terminal device40.

The terminal device40may employ a tablet terminal (slate type PC), which is a mobile terminal which can be connected to the internet.

The terminal device40includes a display unit41that employs a touch panel, an interface unit42for connecting to the internet, a control unit44including a CPU, a memory, and the like, and a speaker47that outputs voice. The above-described display unit41corresponds to a terminal display unit in claims. The above-described speaker47corresponds to a voice output unit in claims.

The terminal device40includes reproduction software that reproduces a digital content memorized in the server device30. The reproduction software is composed of a program having a function that can reproduce (including streaming reproduction which reproduces while downloading) the digital content downloaded from the server device30. A reproduction software A is memorized in a memory unit46such as a semiconductor memory, and reproduction of the digital content is achieved by the control unit44reading out the reproduction software A and executing the same.

The digital content in this embodiment is assumed to be electronic books. Examples of representative standards of the electronic books include DAISY standard for digital recorded books.

The electronic book data of the DAYSY standard include smil (Synchronized Multimedia Integration Language) file, an ncc file or an ncx file in which title information is described, an html file or an xml file in which text data which can be displayed on the display unit41is described, and a voice data file in which the text data is read out.

The smil file is a sort of markup language, in which the order of display of the respective phrases in the html file or the xml file, and reproduction starting and ending times of the voice data file corresponding to the respective phrases are described.

In the terminal device40, when the control unit44executes the reproduction software A, the text data is displayed on the display unit41for each phrase of predetermined digital content. When an operator (student) of the terminal device taps the play button50described later, a voice data file of a portion corresponding to the text data displayed on the display unit41is synchronized with the text data, and a voice is output from the speaker47.

In association with the execution of the reproduction software A, a screen as illustrated inFIG. 3, for example, is displayed on the display unit41of the terminal device40.

In the example illustrated in this drawing, part of a text in a digital content is displayed from a right to a left direction. Under the text, the play button50, a fast-forward button52, a rewind button54, a next page button56, and a front page button58are displayed.

As the display unit41is a touch panel, when the operator (student) taps any above-described one of the play button50, the fast-forward button52, the rewind button54, the next page button56, and the front page button58, or directly taps the phrase desired to listen, the reproduction software A executes the respective operations.

For example, when the operator (student) taps the play button50, the reproduction software A reproduces a voice data file corresponding to the text displayed on the display unit41.

When reproduction of the voice data file is terminated, the operator (student) may reproduce the same phrase again by tapping the rewind button54if comprehension is not sufficient.

In order to proceed the next page, tapping the next page button56causes the reproduction software to display a text of a next phrase on the display unit41.

When reproduction of the voice data file is performed, ID information and reproduction start time of the phrase for each phrase are memorized in the memory unit46as reproduction log data. In addition, examples of the reproduction log data also include data including time and date, operation information operated on the terminal device40(operation of the play button and the stop button), reproduction information (content of the phrase), and set value change information from the server device30.

The reproduction software also covers pinch-in and pinch-out operations. When the operator (student) performs the pinch-in operation, the reproduction software reduces respective characters displayed on the display unit41to display a larger number of characters. Therefore, the number of characters to be displayed in one screen is increased.

In contrast, when the operator (student) performs the pinch-out operation, the reproduction software enlarges the respective characters displayed on the display unit41and reduces the displayed number of characters. Therefore, the number of characters displayed in one screen is reduced.

Although a reproduction time per screen changes as well in association with the pinch-in or the pinch-out operation, the pinch-in or the pinch-out operation may also be recorded as the reproduction log data by memorizing the first phrase and the last phrase displayed in the screen as a log together with the reproduction time in one phrase unit. In the same manner, a scrolling operation may also be recorded.

After reproduction of one learning digital content has been terminated, all the reproduction log data memorized in the memory unit46is transmitted to the server device30together. Transmission of the reproduction log data may be performed at a timing when the reproduction by the reproduction software A is terminated.

However, the transmission of the reproduction log data by phrase to the server device30may be performed every time when detection of the reproduction time in one phrase is terminated.

A configuration of the server device30is illustrated inFIG. 4.

The server device30may employ a general computer (PC). The server device30includes a memory unit60including an HDD and the like in which the learning digital content is memorized, an interface unit62for connecting to the internet, a control unit64including a CPU, a memory and the like, a display unit63including a monitor and the like, and an input unit65including a mouse, a keyboard, and the like.

The above-described display unit63corresponds to a server display unit in claims, the above-described interface unit62corresponds to a receiver unit in claims, the above-described memory unit60corresponds to a digital content memory unit in claims, and the above-described control unit64executes display software described later to realize a display control unit in claims.

In the server device30, the reproduction log data transmitted from the respective terminal devices40are received by the interface unit62and are memorized in the memory unit60.

The control unit64of the server device30is capable of converting the reproduction log data memorized in the memory unit60(including at least ID information by phrase and reproduction start time by phrase) into time spent on reproduction by phrase and the number of times of reproduction by phrase, and causing the display unit63to display the converted time spent on reproduction by phrase and number of times of reproduction by phrase. In other words, a data conversion unit in claims corresponds to the control unit64which realizes a data conversion function.

Here, a configuration of the reproduction log data is illustrated inFIG. 5.

The reproduction log data to be generated by each of the respective terminal devices40includes times and dates when any operation buttons are operated, content of operation, states of the terminal device40, titles, reproduction file names, phrase IDs, and text data of the corresponding phrases.

The control unit64calculates time spent on reproduction of each phrase based on the reproduction start time by phrase and the reproduction start times of the next phrase. The control unit64calculates the number of times of reproduction of each phrase based on the number of the same file names existing for each file name by phrase.

Display of times spent on reproduction of the respective phrases and the numbers of times of reproduction of the respective phrases calculated from the reproduction log data by the control unit64is executed by display software B memorized in the memory unit60in advance.

FIG. 6is a graph displayed on the display unit63, and indicates the times spent on reproduction of the respective phrases and the numbers of times of reproduction of the respective phrases in the same terminal device for the same learning digital content at different times and dates of reproduction.

In this graph, a lateral axis represents time and a vertical axis indicates the learning digital content in which a text is divided into predetermined ranges (by phrase range) so that a beginning of the text comes to a top and an end of the text comes to a bottom. The numbers of times of reproduction are shown by a bar graph on a right side of the graph with the lateral axis representing the number of times of reproduction.

Specifically, in a column along the vertical axis, the text of the learning digital content is divided by phrase range, and the divided strings are displayed from the top in order. The times spent on reproduction corresponding to these phrases are indicated by the length of the squares along the lateral axis.

The colors of the squares indicating the times spent on reproduction corresponding to the respective phrases at different times and dates of reproduction are controlled to be different from each other so as to allow discrimination of the times and dates of reproduction. In this configuration, the times spent on reproduction according to the difference in time and date of reproduction can be figured out easily.

When focusing on an inclination of time spent on reproduction from the beginning of the text to the end of the text, the longer the reproduction time, the longer the entire graph extends in the lateral direction, correspondingly, so that the comprehension level and the achievement level of the student can be figured out by the inclination of the graph.

In other words, if the inclination of the graph is gentle, the longer reproduction time is needed, so that the comprehension level of the student may be determined to be low, and if the inclination of the graph is steep, the shorter reproduction time is sufficient so that the comprehension level of the student may be determined to be high.

By comparing the times spent on reproduction at different times and dates of reproduction, if the inclination of the graph becomes steeper as the time and date of reproduction go on, the operator of the server device30can determine that the comprehension level shows good progress.

When the inclination of the graph is relatively steep from the beginning, there is a case where the inclination of the graph does not change even when the time and date of reproduction go on. In such a case, it is assumed that the comprehension level is high from the beginning, and the improvement of the comprehension level could not achieved any longer. In such a case, settings may be changed to increase a reproduction speed of the learning digital content.

Note that points where the frequency of reproduction is high may be determined from the bar graph indicating the reproduction frequency on the right end of the graph, and points where the reproduction time is long may also be determined, so that points difficult to comprehend in the text for the student may easily be figured out.

As described thus far, the operator of the server device30(educator) may conduct tutorship which meets the corresponding student by watching time spent on reproduction at different times and dates.

Also, the operator of the server device30(educator) may set creating conditions used for creating the learning digital content for a learning process as described thus far. In other words, a unit of division of the content may be optimized depending on the achievement level of learning. For example, the unit of division of the content may be set to increase the number of characters from clauses, punctuation, and paragraph in this order every time when the achievement level is improved. Examples of other creating conditions used for creating the learning digital content include presence or absence of readings and the size of characters included in setting conditions.

An example in which the terminal device40itself displays as illustrated inFIG. 6will be described.

A configuration of the terminal device40in this case is illustrated inFIG. 7. The same components as the components described above may be designated by the reference numerals, and description may be omitted.

The control unit44of the terminal device40converts the reproduction log data memorized in the memory unit46(including at least ID information by phrase and reproduction start time by phrase) into time spent on reproduction by phrase and number of times of reproduction by phrase.

Then, the control unit44executes the display software B so that the times spent on reproduction by phrase at different times and dates of reproduction and the numbers of times of reproduction by phrase may be displayed on the same display unit41.

By the display software B being executed, for the times spent on reproduction by phrase and the numbers of times of reproduction by phrase at different times and dates of reproduction to be displayed on the display unit41the same content as the content illustrated inFIG. 6is displayed.

In the embodiment described thus far, reproduction of the recorded voice data has been described. However, a TTS (Text To Speech) system that converts text data into voice data without having recorded voice data may also be employed. However, when the TTS system is employed, a control unit provided with a TTS function needs to be provided in the terminal device40.

According to the embodiment described above, the times spent on reproduction by phrase and the numbers of times of reproduction by phrase at different times and dates of reproduction may be displayed on the same screen. Therefore, the operator of the server device30(educator) may determine problems relating to reading of each of the students by collectively watching whether reproduction has been made according to the progress of learning, whether a reproduction method meeting the difficulty in reading of each student was applied, whether there is unbalanced distribution of reading frequency, whether the right position of the text could be referenced when an examination was conducted, whether homework has been performed as instructed (a case where the terminal device is brought back home), whether there is a sign of improvement of comprehension level such as the reproduction speed is increased or the times of repetition is reduced in the latter half, and the like.

Then the educator or the like may proceeds to support based on improvements of setting conditions on voice reproduction and the operating method and the like.

Although various modes of the present invention have been described with a preferred embodiment, the present invention is not limited to this embodiment, and a number of modifications may be made without departing the spirit of the invention, as a matter of course.
