Electronic story boards using PowerPoint can display still images sequentially, but do not fully support CG animation. Further, these are centered on 2-dimensional (2-D) images. Research on fully 3-D animation teaching material for astronomy [4] using C programming language and Open GL has been reported. But OpenGL requires specific technical knowledge and preparation of computing environment, and thus is difficult to apply directly in elementary schools. Generally, elementary schools will have limited computing environments compared to colleges. Further, elementary school teachers have many class hours as well as other duties, so time in creating new teaching material is often very limited. Therefore, when introducing CG animation teaching materials in elementary schools, the system must be easily installed in standard computing equipment in elementary schools and the electronic teaching material must be easily modified and extended in short periods of time. It is possible to teach many subjects with Computer Graphics in schools We developed 3-dimensional CG animation teaching materials using CG programming language CG Material is effective for Education in elementary schools Development policy Development environment Development procedure PentiumD-2.8GHz, 512MB-RAM PC running Windows XP for the OS was used for development. POV-Ray [5] was used for developing CG animation. The reasons for selecting POV-Ray are the following. CG animation teaching material was developed with emphasis on the following 3 points. Consideration of teaching material contents (1) CG animation material to follow textbook contents The CG animation teaching material is aimed at rousing the interest of the students towards the contents of the textbooks, and to improve the comprehension of the textbook contents. (2) CG animation material to run on standard PC hardware Elementary school computing hardware specification may be limited compared to college and other higher education institutes. (3) CG animation material to be easily modifiable and extendible Elementary school teachers often have limited time to spend on preparing new teaching material. Creation of draft image • POV-Ray provides an efficient development environment. • POV-Ray is freeware that is widely used thought the world. Since POV-Ray is freeware, the software can be installed without financial restrictions. • There are a large number of references and sample program resources which can be easily retrieved through the Internet. • The programs can be easily modified and extended by beginners. Creation of CG for each scene Creation of CG animation 3-dimentional CG animation teaching materials CG animation Fig.1 shows an example of a developed teaching material used in language (Japanese) class for 1st, 2nd, 3rd grade elementary school class and Fig.2 shows animations of individual scenes. The story is an original story. The outline of each scene is described below. (a) Scene1 (b) Scene2 (f) Scene6 (a) Scene1 (b) Scene2 (e) Scene5 (c) Scene3 (d) Scene4 Fig.1 Language (Japanese) teaching material. (c) Scene3 (1) Scene 1 A young crow feels the moonlight and looks up towards the sky. The young crow decides to look for a place where the beautiful moon can be seen well. (2) Scene 2 The young crow meets a raccoon. The raccoon tells the crow that the moon can be seen well from a tall mountain. (3) Scene 3 The young crow meets a lost squirrel on the way to the mountain. The crow helps to find the lost squirrel’s home from the sky. (4) Scene 4 The young crow next meets a sly fox. The young crow asks the fox for directions to the mountain, not knowing that the fox was a trickster. The fox lies to the young crow and gives false directions. (5) Scene 5 The young crow becomes lost and flies anxiously. A kind owl shows the crow the exit of the forest. (6) Scene 6 Upon arriving home, the young crow realizes that the beautiful moon can be best seen from the top of the tallest tree in the very forest he lives in. (d) Scene4 (e) Scene5 (f) Scene6 Fig.2 Animations of individual scenes. POV-Ray scene file Conclusions References Developers must create program source code that the object and background definitions and control section are clearly separated so that users can easily find and modify the necessary sections of the source code. (Fig.3) • When using CG animation as teaching material, the contents can be modified and extended by changing only the necessary parts of the program source code, most often sections which describe the motion or rotation of objects. • Installing the developed teaching material and making the required modification and extensions to the program source code of the teaching material to match the needs for individual school classrooms is the realistic approach.
