  The processing until the lesson starts is executed between the teacher web management unit 234 and the teacher terminal device 400, and between the student web management unit 235 and the student terminal device 500. The process will be described separately. These processes are processes that proceed in parallel with each other, but for convenience of explanation, the processes executed between the teacher web management unit 234 and the teacher terminal device 400 will be described first. The teacher web management unit 234 executes processing executed in response to a request (instruction) from the teacher terminal device 400 among the class-related processing. The page information transmission unit 2341 of the teacher web management unit 234 is a functional unit that transmits web page data (page information) displayed on the display unit 150 of the teacher terminal device 400. The page information management unit 2342 of the teacher web management unit 234 receives a request (operation / instruction) from the teacher terminal device 400, and the page information transmission unit 2341 described above receives the request (operation / instruction) from the teacher terminal device 400. Is a functional unit that executes creation / selection / switching of page information to be transmitted.

  The processing by the teacher web management unit 234 is started when the teacher terminal device 400 accesses the teacher web management unit 234 by an operation of a teacher who wants to conduct a lesson. The teacher terminal device 400 accesses the teacher web management unit 234 by accessing a predetermined URL using the browser 125. When the teacher terminal device 400 accesses the teacher web management unit 234, the authentication page shown in FIG. 8 is displayed on the display unit 150 of the teacher terminal device 400. The teacher terminal device 400 executes an authentication process with the teacher web management unit 234 in accordance with the teacher's operation (step [1]). Specifically, the teacher terminal device 400 transmits the school ID and the login ID to the teacher web management unit 234 in accordance with the teacher's operation. The teacher web management unit 234 determines whether or not to authenticate the transmitted school ID and login ID by comparing with a pre-registered ID. In addition, the teacher web management unit 234 receives the school ID, so which school site (for example, the site of the school SC1 or the site of the school SC2) is accessed by the teacher terminal device 400. Judging.

  When access to the teacher web management unit 234 from the teacher terminal device 400 is authenticated by the teacher web management unit 234, the class preparation process is performed between the teacher terminal device 400 and the teacher web management unit 234. Executed (step [2]). The class preparation process is performed according to the instruction of the teacher using the class preparation page as a GUI. The class preparation page includes a class creation page shown in FIG. 9 and an image upload page shown in FIG.

  Specifically, first, a lesson creation page (FIG. 9) is displayed on the display unit 150 of the teacher terminal device 400. The teacher operates the teacher terminal device 400 to input necessary items (teacher in charge, site name (school name), category, event, grade, group) on the lesson creation page, and the “Next” button B1 Click. The teacher name and the site name (school name) may be automatically specified from the school ID and login ID transmitted to the teacher web management unit 234 and may be input in advance. When the button B1 is clicked, the teacher terminal device 400 transmits the input value of each item to the teacher web management unit 234.

  Next, an image upload page (FIG. 10) is displayed on the display unit 150 of the teacher terminal device 400. The image G displayed in the image display area GA of the image upload screen is an image selected as an image to be displayed on a teacher class page described later. The teacher drags and drops the image file of the image to be selected to the image display area GA, or displays the file selection screen by clicking the image addition button B2 and selects the image file of the selected image. Select an image to be displayed on the teacher lesson page. The images displayed on the teacher class page include, for example, images of image data generated by reading a picture drawn by a student with a scanner, and images of image data obtained by photographing a work produced by a student with a digital camera. Conceivable.

  When all the images displayed on the teacher lesson page are selected, the teacher clicks the “Next” button B3. When the button B3 is clicked, the image data of the selected image is uploaded to the web server device 200. The uploaded image data is stored in the image data folder 248 described above. When the uploading of the image data of the selected image is completed, the class preparation process is ended.

  When the class preparation process is completed, the teacher web management unit 234 registers the contents of the class prepared by the class preparation process in the class database 244 (step [3]). Specifically, the teacher web management unit 234 uses the values of the transmitted items (the teacher in charge, the site name (school name), the category, the event, the grade, and the group) to correspond to the items in the class database 244 described above. Register new information in the column. The teacher web management unit 234 registers the file name of the uploaded image in the image group column. At this point, in the lesson database 244, the title and name columns of the newly created lesson are not entered, and the start date and time are not yet started (FIG. 5: registered in the top row). See the lessons that have been made).

  When the contents of the lesson are registered, a dialog box as shown in FIG. 11 is displayed on the display unit 150 of the teacher terminal device 400. When the user clicks the “OK” button B4 in the dialog box, the teacher terminal device 400 transmits a lesson start request to the teacher web management unit 234 (step [4]). The class start request is associated with one of a plurality of classes registered in the class database 244. In other words, the lesson start request may include information such as the teacher in charge to identify the lesson, category, event, grade, group, etc., and the lesson can be performed by operating the dialog box displayed immediately after the image upload screen. When the start request is transmitted, the teacher web management unit 234 may automatically determine the class in which the image data is uploaded on the image upload screen as the class associated with the class start request. When the class start request is received, the page information management unit 2342 of the teacher web management unit 234 reads information on a class to be started from the class database 244 (step [5]). The page information management unit 2342 creates teacher class data (page information) using the read information (step [6]). Specifically, the page information management unit 2342 is read from the lesson database 244 based on an HTML file that is a model of the teacher lesson page stored as one of the teacher web information in the web information database 242. The value of each item is described, and the teacher class page is created by associating the image data of the image to be displayed.

  Subsequently, the teacher web management unit 234 registers the class start in the class database 244 (step [7]). Specifically, the start date and time column shown in FIG. 5 is changed from “not started” to date and time information indicating the current date and time (see FIG. 5: top and second levels).

  Following the registration of the class start, the page information transmission unit 2341 transmits the page information of the teacher class page created by the page information management unit 2342 to the teacher terminal device 400. As described above, when the page information transmitted to the teacher terminal device 400 is switched to the teacher lesson page, the page displayed on the teacher terminal device 400 is changed from the lesson preparation page shown in FIG. The teacher class page shown in FIG. The lesson is started when the teacher lesson page is displayed on the teacher terminal device 400.

  Next, processing executed between the student web management unit 235 and the student terminal device 500 will be described. The student web management unit 235 executes processing executed in response to a request (instruction) from the student terminal device 500 among the class-related processing. The page information transmission unit 2351 of the student web management unit 235 is a functional unit that transmits web page data (page information) displayed on the display unit 150 of the student terminal device 500. The page information management unit 2352 of the student web management unit 235 receives a request (operation / instruction) from the student terminal device 500, and the page information transmission unit 2351 described above receives the request (operation / instruction) from the student terminal device 500. Is a functional unit that executes creation / selection / switching of page information to be transmitted.

  The processing by the student web management unit 235 is started when the student terminal device 500 accesses the student web management unit 235 by an operation of a student who wants to take a class. The student terminal device 500 uses the browser 125 to access a predetermined URL (different from the URL for accessing the teacher web management unit 234 described above), thereby allowing the student web management unit 235 to access the student web management unit 235. to access. When the student terminal device 500 accesses the student web management unit 235, an authentication page (not shown) is displayed on the display unit 150 of the student terminal device 500. The student terminal device 500 executes an authentication process with the student web management unit 235 in accordance with a student operation (step [a]). Specifically, the student terminal device 500 transmits the school ID to the student web management unit 235 in accordance with the student's operation. The student web management unit 235 determines whether to authenticate the transmitted school ID by comparing it with a pre-registered ID. In addition, the student web management unit 235 determines which school site is accessed by the student terminal device 500 by receiving the school ID.

  When access to the student web management unit 235 from the student terminal device 500 is authenticated by the student web management unit 235, the page information transmission unit 2351 of the student web management unit 235 sends the student terminal device 500 to the student terminal device 500. Then, the standby page data (page information) is transmitted (step [b]). As a result, the standby page shown in FIG. 13 is displayed on the display unit 150 of the student terminal device 500. Thereby, the student who operates the student terminal device 500 recognizes that the lesson has not yet started, and waits for the lesson to start.

  The page information of the standby page is associated with a program (reload program) that causes the student terminal device 500 to periodically reload the page information. For example, the reload program is described using a client-side script such as Java (registered trademark) Script or VBScript, and is included in an HTML file that is page information of a standby page. As a result, while the standby page is displayed, the browser 125 of the student terminal device 500 periodically issues a reload request for updating the page information (for example, at an interval of 10 seconds). (Step [c] and step [f]).

  Upon receiving the reload request, the page information management unit 2352 of the student web management unit 235 searches for the lesson start (step [d] and step [g]). The class start search is a process of searching whether or not a class to be transmitted to the student terminal device 500 that has transmitted the reload request is registered in the class database 244. Specifically, the page information management unit 2352 has the school ID received from the student terminal device 500 in the above-described authentication process (step [a]) in the class registered in the class database 244. Whether or not there is a class whose start date and time is within a predetermined period from the current time is determined. The predetermined period is set to 24 hours, for example. If the page information management unit 2352 determines that there is no lesson that meets the condition, the page information transmission unit 2351 retransmits the page information of the standby page to the student terminal device 500. In the example shown in FIG. 7, at the timing of the class start search in step [d] executed in response to the reload request in step [c], before the class start registration (step [7]) described above is performed. is there. Therefore, it is determined that there is no lesson that meets the condition, and the page information of the standby page is retransmitted (step [e]).

  On the other hand, when the page information management unit 2352 determines that there is a class that satisfies the condition, the page information of the student class page for the class is transmitted to the student terminal device 500. This will be described in detail with reference to the example shown in FIG. 7. At the timing of the class start search in step [g] executed in response to the reload request in step [f], the class start registration described above (step [7]). After that is done. Accordingly, it is determined that there is a class that meets the condition, and the page information management unit 2352 first reads information on the class from the class database 244 (step [h]). The page information management unit 2352 uses the read information to create student class page data (page information) (step [i]). Specifically, the page information management unit 2352 is read from the lesson database 244 based on an HTML file that is a model of a student lesson page stored as one of the student web information in the web information database 242. The value of each item is described, and the student class page is created by associating the image data of the image to be displayed.

  The page information transmission unit 2351 transmits the page information of the student class page created by the page information management unit 2352 to the student terminal device 500. As described above, when the page information transmitted to the student terminal device 500 is switched to the student lesson page, the page displayed on the student terminal device 500 is changed from the standby page shown in FIG. It is automatically switched to the student class page shown in. When the student class page is displayed on the student terminal device 500, the student recognizes that the class has started.

  According to the processing described above, when the teacher web management unit 234 switches the page information transmitted to the teacher terminal device 400 from the lesson preparation page to the teacher lesson page, the student web management unit 234 235 switches the page information transmitted to the student terminal device 500 from the standby page to the student lesson page. Therefore, in conjunction with the page switching in the teacher terminal device 400, the page switching is automatically performed in the student terminal device 500. As a result, the class can be automatically started in the student terminal device 500 without the student operating the student terminal device 500.

  Further, although data of a plurality of lessons are registered (prepared) in the web server device 200, a student lesson page having contents corresponding to the lesson content of the teacher lesson page transmitted to the teacher terminal device 400 is automatically generated. And transmitted to the student terminal device 500. Therefore, the student can display the lesson page with the contents suitable for the teacher on the student terminal device 500 without performing troublesome operations such as specifying the lesson contents and inputting the corresponding URL.

  Further, since the reload program is associated with the standby page, the browser 125 of the student terminal device 500 automatically reloads periodically. As a result, it is possible to easily switch from the standby page described above to the student lesson page, triggered by periodic reloading.

  Next, with reference to FIGS. 15 to 21, processing after class start will be described in the class related processing. FIG. 15 is a second flowchart showing a processing routine of class related processing. FIG. 16 is an explanatory diagram illustrating an example of a name input page. FIG. 17 is an explanatory diagram illustrating an example of a title input page. FIG. 18 is an explanatory diagram showing how the teacher lesson page is updated. FIG. 19 is an explanatory diagram showing an example of a dialog box for transmitting a lesson end request. FIG. 20 is an explanatory diagram showing an example of a homepage publication registration page. FIG. 21 is an explanatory diagram illustrating an example of a homepage.

  For convenience of explanation, processing executed between the student web management unit 235 and the student terminal device 500 will be described first. When the lesson starts, an image information input process is executed between the student web management unit 235 and the student terminal device 500 in accordance with the student's operation (step [k], step [m]). . The image information input process is a process for inputting image information as new information to the contents of the class associated with the student web page, that is, the information of the class registered in the class database 244. is there. When there are a plurality of students, these processes are executed by a plurality of students, so that these processes can be executed a plurality of times. In the example shown in FIG. 7, two image input processes of step [k] and step [m] are shown. The image information is information associated with images used in the lesson (images displayed on the student and teacher image pages), and is registered for each image in the lesson database 244 described above. In the present embodiment, the title and the name provided with the column to be registered in the class database 244 described above correspond to the image information.

  The image information input process will be specifically described. In the student lesson page shown in FIG. 14, the student operates the student terminal device 500 and clicks and selects an image to be input image information. Work sequentially on the page. For example, when an image to be input is selected and the orientation of the images is adjusted, a name input page shown in FIG. 16 is displayed on the student terminal device 500. This page is displayed so that the name of the student list registered by the site management unit 232 can be selected. The student operates the student terminal device 500 and clicks and selects his / her name. Next, since the title input page shown in FIG. 17 is displayed on the student terminal device 500, the student operates the student terminal device 500 to input the title of the image. The student name and picture title input in this way are transmitted from the student terminal device 500 to the student web management unit 235. The page information management unit 2352 of the student web management unit 235 adds the transmitted name and title (image information) to the corresponding fields of the lesson database 244 (step [l] and step [n]). As a result, the content of the lesson associated with the student lesson page (the lesson information registered in the lesson database 244) is changed.

  Next, processing executed between the teacher web management unit 234 and the teacher terminal device 400, which proceeds in parallel with the above-described steps [k] to [n], will be described. The reload information similar to the page information of the standby page described above is associated with the page information of the teacher class page transmitted to the teacher terminal device 400 in step [8] described above. As a result, after the lesson starts, the browser 125 of the teacher terminal device 400 periodically issues a reload request for updating the page information (for example, every 10 seconds) while the teacher lesson page is displayed. This is transmitted to the teacher web management unit 234 (step [9] and step [13]).

  When the page information management unit 2342 of the teacher web management unit 234 receives the reload request, the page information management unit 2342 previously displays the teacher class page transmitted to the teacher terminal device 400, that is, currently displayed on the teacher terminal device 400. The class information corresponding to the teacher class page being read is read from the class database 244 (step [10] and step [14]). The page information management unit 2342 updates the teacher class page data (page information) using the read information (step [11] and step [15]). The page information transmission unit 2341 transmits the page information of the teacher class page created by the page information management unit 2342 to the teacher terminal device 400 (step [12], step [16]).

  In the example shown in FIG. 15, the above-described image information (name and title) is added (step [l]) at the reading timing of class information in step [10] executed in response to the reload request in step [9]. Is before. Therefore, since the lesson database 244 has not been updated at all, the reading of lesson information in step [10] reads the same information as the reading of lesson information at the time of creating the lesson page for teachers (step [5]). It is. In step [11], the same page as the teacher lesson page created in step [6] is created. In step [12], the same teacher lesson page is sent to the teacher terminal device 400. Sent.

  On the other hand, at the reading timing of class information in step [14] executed in response to the reload request in step [13], after the above-described addition of image information (name and title) (step [l]) is performed. It is. Therefore, since image information is added to the lesson database 244, in the reading of lesson information in step [10], information including the newly added image information is read as lesson information. As a result, in step [15], a page in which the description of the image information (name and title) is added to the teacher class page created in step [6] is created. In step [16], the image information is created. Is added to the teacher terminal device 400.

  As a result, the teacher class page to which the name NA and the title SN are added as image information as shown in FIG. 18 is displayed on the display unit 150 of the teacher terminal device 400. Thereafter, until the lesson is completed, the processing from step [13] to step [16] is repeatedly executed, and when other students add image information using the student terminal device 500, the teacher terminal device 400 The added image information is displayed in real time on the displayed teacher lesson page.

  When the teacher operates the teacher terminal device 400 and clicks the button B5 on the teacher lesson page shown in FIG. 19, a dialog box for transmitting a lesson end request shown in FIG. 20 is displayed. When the teacher operates the teacher terminal device 400 and clicks the “OK” button B6 in the dialog box, a lesson completion request is transmitted from the teacher terminal device 400 to the teacher web management unit 234 (step S40). [17]). Upon receiving the class end request, the page information management unit 2342 of the teacher web management unit 234 reads the final class information from the class database 244 (step [18]), and uses the read class information. Create page information for the website registration page. The page information transmission unit 2341 of the teacher web management unit 234 transmits the page information of the created homepage publication registration page to the teacher terminal device 400 (step [19]). As a result, the homepage publication registration page shown in FIG. 20 is displayed on the display unit 150 of the teacher terminal device 400.

  The homepage publication registration page is used as a GUI for the teacher to select an image to be disclosed on the school homepage from images used in the class. As shown in FIG. 20, when the teacher operates the teacher terminal device 400 to check a check box of an image to be posted, the image file of the image is the above-described homepage database as an image to be posted on the homepage. H.246 is registered.

  In FIG. 20, an image in which the corresponding check box is checked by the teacher is posted on the school homepage as shown in FIG. 21, and can be freely viewed by students and teachers. To be. The creation and browsing management of these home pages and the management of the home page database 246 are executed by the home page management unit 236 (FIG. 2) described above. The homepage management unit 236 has a function of automatically creating a homepage by using an HTML file included in the web information for homepage included in the web information database 242 as a model, associating an image file of an image to be posted in the HTML file It has.

  According to the processing described above, when the content of the lesson associated with the student lesson page is changed by the student terminal device 500, the change is made to reflect the change of the lesson content in the teacher terminal device 400. The teacher's lesson page is displayed. Therefore, although the teacher terminal device 400 and the student terminal device 500 are browsing different web pages, the web information (web page) is linked to each other without any special operation from the terminal device. ) Can be viewed.

  Since the reloading program is associated with the teacher lesson page, the browser 125 of the teacher terminal device 400 automatically reloads periodically as with the browser 125 of the student terminal device 500. As a result, the above-described change in the content of the lesson can be easily reflected on the lesson page for teachers, triggered by periodic reloading.
