[0004] By the way, when a school introduces digital teaching materials, it is necessary to consider whether the materials fit the teacher's teaching style. The producers of digital teaching materials also want to have schools try the digital teaching materials that best meet their needs, so as to lead to a subsequent contract conclusion. It is common for trial versions of digital teaching materials to have a usage period of a certain length (about one month to half a year), allowing users to experience some of the digital teaching materials. However, producers cannot determine the effect of the trial version until after the usage period of the trial version has expired. Therefore, producers cannot take actions leading to a contract conclusion during the usage period. Furthermore, even if an action is taken after it becomes clear that there is no prospect of a contract once the trial version has ended, it is considered that the effect on concluding a contract is limited.

[0005] An object of the present invention is to provide a digital content proposal apparatus, a digital content proposal method, and a program capable of encouraging users to use trial version digital content. [[Means for Solving the Problems]]

[0006] In one embodiment, the digital content suggestion device includes a suggestion unit that suggests trial digital content to a user, and an acquisition unit that monitors the user's usage status by acquiring information on the user's usage status of the trial digital content, wherein the suggestion unit suggests other trial digital content to the user based on the usage status information. [Effects of the Invention]

[0007] According to the above embodiment, users can be encouraged to use the trial version of the digital content. [Brief explanation of the drawing]

[0008] [Figure 1] This is an explanatory diagram showing the configuration of a digital content suggestion device according to one embodiment. [Figure 2] This figure shows a computer (an example of hardware configuration for a digital content suggestion device) in one embodiment. [Figure 3] This is a table showing school information, including user attributes (school attributes), and the usage time of the trial version of the digital teaching material, in one embodiment. [Figure 4] This table shows the average usage time and content attributes of a trial version of digital content in one embodiment. [Figure 5] This is a sequence diagram illustrating the processing of a digital content suggestion device and a school terminal in one embodiment. [Modes for carrying out the invention]

[0009] Hereinafter, a digital content suggestion device, a digital content suggestion method, and a program according to one embodiment of the present invention will be described with reference to the drawings.

[0010] Figure 1 is an explanatory diagram showing the configuration of a digital content suggestion device 1 according to one embodiment.

[0011] As shown in Figure 1, the digital content suggestion device 1 comprises a control unit 10, a receiving unit 20, a transmitting unit 30, a digital teaching material storage unit 40, and a school information database 50. The digital content suggestion device 1 is, for example, a server device such as a cloud server. The functions of the digital content suggestion device 1 may be performed by a digital content management device or a digital content sales device. In other words, the digital content management device or the digital content sales device may also function as the digital content suggestion device 1.

[0012] The suggestion unit 11 of the control unit 10 suggests trial digital teaching materials (examples of trial digital content) L1, L2, and Ln to the school (an example of a user). Furthermore, as will be described in more detail later, the suggestion unit 11 suggests other trial digital teaching materials L1, L2, and Ln to the school based on the school's usage information of the trial digital teaching materials L1, L2, and Ln.

[0013] In this embodiment, the proposal of trial digital teaching materials L1, L2, and Ln by the proposal unit 11 is carried out by providing (transmitting) the trial digital teaching materials L1, L2, and Ln to the school (school terminal 200 shown in Figure 5). Furthermore, as a prerequisite for providing the trial digital teaching materials L1, L2, and Ln to the school, it is assumed that, for example, the teacher's school terminal 200 has already acquired a digital teaching material execution application (digital content execution application) such as a learning support system. Then, the lesson is conducted with the student terminals having acquired and running the student-oriented digital teaching material execution application. Note that the school is, for example, an elementary school, but may also be a kindergarten, junior high school, compulsory education school, high school, secondary school, special needs school, university, technical college, etc.

[0014] The acquisition unit 12 of the control unit 10 monitors the usage status of the school by acquiring information on the usage status of the school's trial version of digital content. The acquisition unit 12 may acquire usage information at predetermined intervals, such as once a day or each time the school terminal 200 accesses the digital teaching material execution application.

[0015] Furthermore, the control unit 10 may also manage usage periods such as the "trial start date" and "trial end date" shown in FIG. 3 for each trial digital teaching material L1, L2, Ln.

[0016] The receiving unit 20 receives requests for use of trial digital teaching materials L1, L2, Ln from users such as schools.

[0017] The transmitting unit 30 proposes a plurality of trial digital teaching materials L1, L2, Ln to users such as schools.

[0018] The digital teaching material storage unit 40 stores trial digital teaching materials L1, L2 provided as trials, trial digital teaching materials Ln which are trial candidates, and the like. Additionally, it stores content attribute A1 and usage time U for each of the trial digital teaching materials L1, L2, Ln.

[0019] The trial digital teaching materials L1, L2, Ln are, for example, any one of a plurality of units included in each subject, and as shown in FIG. 4, they are teaching materials such as "State and Temperature of Water", "AI Automated Cash Register", "Line Graphs", and "Function of Electric Current".

[0020] The content attribute A1 is, for example, as shown in FIG. 4, "with / without deliverable", "with / without programming", "difficulty level", and the like, and is set by, for example, the creator of the trial digital teaching materials L1, L2, Ln or the administrator of the digital content proposing apparatus 1. A deliverable is, for example, a work such as an illustration or product created in class, and when there is a deliverable, class time tends to be longer compared to when there is no deliverable. Therefore, it is preferable that the trial digital teaching materials L1, L2, Ln are selected such that the available class time corresponds to the presence or absence of a deliverable. Furthermore, if the trial digital teaching material L1, L2, Ln includes programming learning content, programming is marked as "present". Difficulty level is represented by, for example, "low", "medium", and "high".

[0021] The usage time U is preferably, for example, as shown in FIG. 3, the school-specific usage time U such as "20" hours for "Water States and Temperature" which is the first "digital teaching material 1" under experience, "110" hours for "AI Automatic Cash Register" which is the second "digital teaching material 2" under experience, and "50" hours for "Line Graph" which is the third "digital teaching material 3" under experience. This school-specific usage time U is an example of school usage status information, and is, for example, the total usage time for one or more teachers and a plurality of students. Note that the usage time U may be an average usage time per day or the like for comparison of usage status described later. Further, the usage time U may be the usage time of only teachers.

[0022] Further, as shown in FIG. 4, for example, the usage time U may include information on the average usage time (an example of usage status information) of contracted schools (an example of contracted users) that have used trial digital teaching materials L1, L2, ..., Ln in the past and purchased digital teaching materials (an example of digital content). Here, the digital teaching material (digital content) to be purchased can be regarded as the digital teaching material execution application (digital content execution application) itself such as a learning support system.

[0023] The school information database 50 stores school-specific user attributes A2 and assignment information P. User attributes A2 may include ICT (Information and Communication Technology) skills (an example of skill information), as shown in Figure 3. This ICT skill can be represented as, for example, "low," "medium," or "high." Such skill information can be set using, for example, survey data or interviews. Furthermore, since the responsible board of education is common to each school region, skill information tends to be common across regions. Therefore, it is acceptable to set skill information that is common to each school region. Assignment information P is information on school-specific assignments, such as "challenges with digital teaching materials." This assignment information P can be set using, for example, survey data or interviews, similar to user attributes A2. Sales representatives for the trial versions of digital teaching materials L1, L2, and Ln may refer to assignment information P when conducting sales. Also, if assignment information P is, for example, programming motivation, it can be treated similarly to user attributes A2 if the motivation is classified as "high," "medium," or "low."

[0024] The digital content suggestion device 1 includes a digital teaching material storage unit 40 and a school information database 50, but at least one of the digital teaching material storage unit 40 and the school information database 50 may be an external database connected to the digital content suggestion device 1 by communication.

[0025] Figure 2 shows an example of the hardware configuration of the computer 100 (digital content suggestion device 1) in this embodiment.

[0026] The computer 100 shown in Figure 2 comprises a processor 110, memory 120, auxiliary storage device 130, input device 140, output device 150, portable recording medium drive device 160 for driving a portable recording medium 180, bus 170, and communication device 190. The auxiliary storage device 130 and the portable recording medium 180 are examples of non-transient computer-readable recording media on which programs are recorded.

[0027] The processor 110 is, for example, one or more arbitrary processing circuits, including a CPU (Central Processing Unit). The processor 110 can function as part or all of the functional components of the digital content proposal device 1 shown in Figure 1 (for example, the proposal unit 11 and the acquisition unit 12) by loading a program stored in the auxiliary storage device 130 or the portable recording medium 180 into the memory 120 and executing it.

[0028] Memory 120 is any semiconductor memory, such as RAM (Random Access Memory). Memory 120 functions as a work memory that stores programs or data stored in the auxiliary storage device 130 or portable recording medium 180 during program execution.

[0029] The auxiliary storage device 130 is, for example, a non-volatile memory such as a hard disk or flash memory. The auxiliary storage device 130 is mainly used to store various data and programs, and can function, for example, as a digital teaching material storage unit 40 and a school information database 50.

[0030] The portable recording medium drive unit 160 houses the portable recording medium 180. The portable recording medium drive unit 160 can output data stored in the memory 120 or auxiliary storage device 130 to the portable recording medium 180, and can also read programs and data from the portable recording medium 180. The portable recording medium 180 is any portable recording medium. Examples of portable recording media 180 include SD cards, USB (Universal Serial Bus) flash memory, CDs (Compact Discs), DVDs (Digital Versatile Discs), etc.

[0031] Input devices 140 include keyboards, mice, etc. Output devices 150 include display devices such as displays and printers.

[0032] The communication device 190 is a wireless or wired communication module. The communication device 190 can function as the receiving unit 20 and transmitting unit 30 shown in Figure 1.

[0033] Bus 170 connects the processor 110, memory 120, auxiliary storage device 130, etc., to enable data exchange.

[0034] The configuration of the computer 100 shown in Figure 2 is merely one example of the hardware configuration of the digital content suggestion device 1 shown in Figure 1, and the digital content suggestion device 1 is not limited to the configuration of the computer 100 shown in Figure 2. The digital content suggestion device 1 may be a general-purpose device or a dedicated device. The digital content suggestion device 1 may include, for example, a specially designed electrical circuit, such as an ASIC (Application Specific Integrated Circuit). Furthermore, the digital content suggestion device 1 may be configured using an FPGA (Field-Programmable Gate Array).

[0035] Next, the processing of the digital content suggestion device 1 and the school terminal 200 will be explained with reference to Figure 5. Note that explanations that overlap with the above explanation will be omitted as appropriate.

[0036] First, the school terminal 200 sends a request to the digital content suggestion device 1 (receiving unit 20) to use the trial versions of the digital teaching materials L1, L2, and Ln (step S1).

[0037] Next, the receiving unit 20 requests the suggestion unit 11 to select and suggest trial digital teaching materials L1, L2, and Ln (step S2). Alternatively, the suggestion unit 11 starts processing for selecting and suggesting trial digital teaching materials L1, L2, and Ln based on the fact that the receiving unit 20 has received the application for use.

[0038] The proposal unit 11 provides (proposes) trial versions of digital teaching materials L1, L2, and Ln to the school terminal 200 (step S3). When providing these initial trial versions of digital teaching materials L1, L2, and Ln, the proposal unit 11 may select them in the same manner as when selecting other trial versions of digital teaching materials L1, L2, and Ln described later (step S8). Alternatively, if the proposal unit 11 includes information such as the desired grade level, subject, and unit at the time of application (step S1), it may select materials that match the school's preferences. If the school's preferences are unknown, the proposal unit 11 may select the standard trial versions of digital teaching materials L1, L2, and Ln, or the most popular (for example, the one with the most usage time) trial versions of digital teaching materials L1, L2, and Ln. The proposal unit 11 may propose one or any number of trial versions of digital teaching materials L1, L2, and Ln to the school, but it is desirable to propose multiple trial versions of digital teaching materials L1, L2, and Ln to the school.

[0039] When the school terminal 200 uses the trial versions of digital teaching materials L1, L2, and Ln (step S4), the acquisition unit 12 monitors the school's usage status by acquiring usage information (e.g., usage time) of the trial versions of digital teaching materials L1, L2, and Ln on the school terminal 200 (step S5). The usage information may be transmitted to the acquisition unit 12 at arbitrary intervals, such as every day.

[0040] Next, the proposal unit 11 receives notification from the acquisition unit 12 of the total usage time of the school at predetermined timings (for example, after one-third and two-thirds of the usage period of the trial digital teaching materials L1, L2, and Ln have elapsed, respectively) (step S6). Alternatively, the proposal unit 11 calculates the total usage time of the school at the above predetermined timings.

[0041] The proposal unit 11 then determines which trial digital teaching materials L1, L2, and Ln have unsatisfactory usage times, i.e., which are to be replaced (step S7). For example, the proposal unit 11 compares the total usage time of each trial digital teaching material L1, L2, and Ln used by each school with the average usage time of contracted schools shown in Figure 4, and determines which trial digital teaching materials L1, L2, and Ln have usage times less than the average usage time of contracted schools to be replaced.

[0042] In the example in Figure 3, of the three digital teaching materials 1-3 that "Elementary School A" with school ID "S0121" is currently experiencing, the usage time of the first "Digital Teaching Material 1," "The Forms and Temperature of Water," is "20" hours (indicated by the diagonal lines), which is less than the average usage time of "70 hours" for contracted schools shown in Figure 4. Therefore, the proposal unit 11 identifies "Digital Teaching Material 1" as a candidate for replacement.

[0043] On the other hand, the 110 hours spent on the second "Digital Material 2," "AI Automated Register," is more than the average time of 100 hours spent by schools that have signed contracts, and the 50 hours spent on the third "Digital Material 3," "Line Graph," is more than the average time of 50 hours spent by schools that have signed contracts. Therefore, the proposal department 11 decides to continue the trial period for "Digital Material 1" and "Digital Material 2," without identifying them as materials to be replaced.

[0044] Furthermore, it is desirable that the usage period be the same for both the school's usage time and the average usage time of the contracted schools when making a comparison. Therefore, it is advisable to compare usage times by converting them to any period, such as one day, one week, or one month, or by comparing them to the average usage time for each period of use of the contracted schools. In addition, the comparison target may not be the average usage time of the contracted schools, but rather half of the average usage time of the contracted schools, or the usage time of the contracted school with the shortest usage time during the trial period. Even in this case, it can be said that the judgment is based on usage information of the contracted schools.

[0045] Next, the proposal unit 11 selects other trial digital teaching materials L1, L2, and Ln to propose to the school terminal 200 (step S8). For example, since the aforementioned "A Elementary School" has "medium" ICT skills and average or above-average programming skills, the proposal unit 11 may select "The Function of Electric Current," which has content attribute A1 "programmed," as a different trial digital teaching material L1, L2, and Ln, unlike "The Forms and Temperature of Water," which was identified as a replacement target. Alternatively, since "The Forms and Temperature of Water" has "no deliverables" and a "low" difficulty level, the proposal unit 11 may select trial digital teaching materials L1, L2, and Ln with different content attribute A1, such as those with "deliverables" or a "medium" or "high" difficulty level. The proposal unit 11 may also select the trial digital teaching material L1, L2, and Ln that had the longest usage time among the contracted schools.

[0046] Furthermore, the proposal unit 11 may propose the alternative trial digital teaching materials L1, L2, Ln selected in this manner by replacing (swapping) the trial digital teaching materials L1, L2, Ln (the state and temperature of water) that have already been proposed to the school (step S9). That is, the proposal unit 11 deactivates the original trial digital teaching materials L1, L2, Ln by deleting them or otherwise. When deactivating the original trial digital teaching materials L1, L2, Ln in this way, the school terminal 200 may be notified in advance that they will be deactivated. Here, the number of trial digital teaching materials L1, L2, Ln before and after the swap does not need to be the same.

[0047] In the above explanation, we described an example where multiple trial digital learning materials (trial digital content) L1, L2, and Ln are executed by a single digital learning material execution application (digital content execution application). However, each of the multiple trial digital learning materials (trial digital content) L1, L2, and Ln may also be a digital learning material execution application (digital content execution application).

[0048] Furthermore, the above explanation used the trial digital content L1, L2, and Ln, which are trial digital teaching materials used by schools, as examples. However, the trial digital content may also be trial digital teaching materials L1, L2, and Ln used by individuals or organizations other than schools, or it may be digital content other than digital teaching materials.

[0049] Furthermore, while the above explanation listed the presence or absence of deliverables, the presence or absence of programming, and the difficulty level as content attribute A1, content attribute A1 may also include other information such as subject information (English or mathematics) or usage information (for classroom use or for testing).

[0050] Furthermore, while the above explanation listed ICT skills as user attribute A2 for the user (school), user attribute A2 may also include other skill information such as subject-specific skills like English, or it may include other information besides skill information, such as target student information (grade level information, etc.).

[0051] Furthermore, in the above explanation, the proposal unit 11 proposes the trial digital teaching materials L1, L2, Ln by providing (transmitting) the trial digital teaching materials L1, L2, Ln to the school (school terminal 200 shown in Figure 5). However, the proposal of the trial digital teaching materials L1, L2, Ln may also be made by other methods, such as requesting the distribution server that distributes the trial digital teaching materials L1, L2, Ln to distribute them to the school, or by notifying (transmitting) the school that is the access destination for downloading the trial digital teaching materials L1, L2, Ln.

[0052] Furthermore, while the above explanation cited usage time as usage information for the trial digital learning materials L1, L2, and Ln, the usage information could also be the number of uses, or the trend of increase or decrease in at least one of the usage time or number of uses. For example, if the usage time per month is gradually decreasing, the suggestion unit 11 should suggest other trial digital learning materials L1, L2, and Ln, and if it is gradually increasing, it should not suggest trial digital learning materials L1, L2, and Ln, but instead allow the user to continue using the original trial digital learning materials L1, L2, and Ln.

[0053] Furthermore, while the above explanation described an example where the average usage time (usage status information) of contracted schools is used to identify the trial digital teaching materials L1, L2, and Ln to be replaced, the trial digital teaching materials L1, L2, and Ln to be replaced may also be identified using, for example, a predetermined usage time arbitrarily set by the administrator of the digital content suggestion device 1.

[0054] In the embodiment described above, the digital content suggestion device 1 comprises a suggestion unit 11 and an acquisition unit 12. The suggestion unit 11 suggests trial digital teaching materials (examples of trial digital content) L1, L2, and Ln to a school (an example of a user). The acquisition unit 12 monitors the usage status of the school by acquiring usage information of the school's trial digital teaching materials L1, L2, and Ln. Based on the usage information, the suggestion unit 11 suggests other trial digital teaching materials L1, L2, and Ln to the school.

[0055] Furthermore, from a methodological standpoint, the digital content proposal method includes proposing trial versions of digital teaching materials (examples of trial versions of digital content) L1, L2, and Ln to schools (an example of users) (step S3 in Figure 5), monitoring the usage status of schools by obtaining usage information of the trial versions of digital teaching materials L1, L2, and Ln (step S5), and proposing other trial versions of digital teaching materials L1, L2, and Ln to schools based on the usage information (steps S6 to S9).

[0056] Furthermore, from a programming perspective, the program enables the computer 100 to implement the following functions: a function to propose trial digital teaching materials (examples of trial digital content) L1, L2, Ln to a school (an example of a user) (step S3); a function to monitor the school's usage by acquiring information on the school's use of the trial digital teaching materials L1, L2, Ln (step S5); and a function to propose other trial digital teaching materials L1, L2, Ln to the school based on the usage information (steps S6-S9).

[0057] In this way, by monitoring the usage status of the trial versions of digital teaching materials L1, L2, and Ln at schools, it is possible to determine the extent to which schools are using the trial versions of digital teaching materials L1, L2, and Ln during the trial period. Therefore, if the trial versions of digital teaching materials L1, L2, and Ln are not being used or are being used for a short time, other trial versions of digital teaching materials L1, L2, and Ln can be suggested to the school. Thus, according to this embodiment, it is possible to encourage schools to use the trial versions of digital teaching materials L1, L2, and Ln. Therefore, compared to an embodiment where usage information and feedback information for the trial versions of digital teaching materials L1, L2, and Ln are obtained from schools after the trial period has elapsed, revealing that the trial versions were not being used or were being used for a short time, it is possible to promote the sale of digital teaching materials.

[0058] Furthermore, in this embodiment, the suggestion unit 11 (a function that suggests or proposes other trial digital learning materials L1, L2, Ln) replaces the trial digital learning materials L1, L2, Ln that have already been suggested to the user with other trial digital learning materials L1, L2, Ln.

[0059] This makes the newly proposed trial digital teaching materials L1, L2, and Ln more eye-catching compared to a scenario where the previously offered trial digital teaching materials L1, L2, and Ln are mixed with the existing ones. Therefore, it is possible to further encourage schools to use the trial digital teaching materials L1, L2, and Ln.

[0060] Furthermore, in this embodiment, the suggestion unit 11 (a function that suggests or proposes other trial digital teaching materials L1, L2, Ln) suggests other trial digital teaching materials L1, L2, Ln to the school based on usage information, school user attributes A2, and content attributes A1 of the trial digital teaching materials L1, L2, Ln.

[0061] This allows us to propose trial versions of digital teaching materials L1, L2, and Ln that are tailored to the specific characteristics (attributes) of each school. Consequently, we can further encourage schools to utilize the trial versions of digital teaching materials L1, L2, and Ln.

[0062] Furthermore, in this embodiment, the proposed trial digital content consists of trial digital teaching materials L1, L2, and Ln, the users of trial digital teaching materials L1, L2, and Ln are schools, and user attribute A2 includes skill information corresponding to content attribute A1.

[0063] This allows us to propose trial versions of digital teaching materials L1, L2, and Ln to schools based on skill information (such as "intermediate" ICT skills) corresponding to content attribute A1, including whether or not the L1, L2, and Ln versions have programming capabilities and difficulty levels. Therefore, we can further encourage schools to use trial versions of digital teaching materials L1, L2, and Ln.

[0064] Furthermore, in this embodiment, the suggestion unit 11 (a function that suggests or proposes other trial digital teaching materials L1, L2, Ln) suggests other trial digital teaching materials L1, L2, Ln to schools based on the school's trial digital teaching materials L1, L2, Ln and the usage information of contracted schools (contracted users) that have previously used these trial digital teaching materials L1, L2, Ln and purchased digital teaching materials (digital content).

[0065] This allows us to determine whether to propose other trial versions of digital learning materials L1, L2, and Ln to schools based on factors such as the average and minimum usage time of users who actually made a purchase. Consequently, the proposals for other trial versions of digital learning materials L1, L2, and Ln become more accurate, and schools are more likely to utilize them.

[0066] It should be noted that the present invention is not limited to the embodiments described above, and the components can be modified and implemented in practice without departing from the spirit of the invention. Furthermore, various inventions can be formed by appropriately combining the multiple components disclosed in the embodiments described above. For example, all the components shown in the embodiments may be combined as appropriate. It goes without saying that various modifications and applications are possible without departing from the spirit of the invention.
