目前國小數學教材中發現,幾何單元課程大多以引導兒童對於幾何圖形的構成要素、組合等進行教學,課本中多以2D 平面視圖表示立體幾何圖像,而實體教具亦有收納等不便問題,因此本研究試圖以Scanimation 動態影像與全像立體影像呈現幾何形體樣貌,提供具有連續影像變化和多視角面貌的立體效果。 研究首先就國小五年級數學幾何單元與教具使用現況,以及動態影像與立體影像之發展可能性進行文獻分析,藉由兩組實驗來探討幾何形體於動態影像與立體影像中清晰度與辨識度最高的影像設計規則,最後延伸實驗結果創作三組幾何形體輔助教材。本研究透過實驗得到以下結果: 1. 黃色為最佳的動態影像之視認性色彩。 2. 對於兒童來說,動態影像的線條間距為0.6 公厘比成人的0.3 公厘、0.4 公厘即可完整辨識圖像有很大的差別。 3. 動態影像的變圖張數以3 張、4 張為連續性較佳的效果。 4. 在反射式全像椎體底圖與背景灰階組合搭配中,灰階40%的虛像、以及灰階0%實像為最佳辨識之影像。 另外兒童對於反射式全像虛像有較高的喜好。
In elementary mathematics, geometry curriculum teaches the children elements of geometry. It is always using 2D images to explain three-dimensional geometry images in textbooks. However, geometry teaching has some problem of storage, so we try to use the scanimation and hologram to show stereo images of geometric shapes, providing a continuous changing and multi-angle images. The study begins with the analysis and integration of geometry, geometry teachings,scanimation and hologram, and then explores the design principle of scanimation and hologram through two experiments. The experiment conclusions are used to create three products. The conclusions are shown below: 1. Yellow is the best color of represent scanimation images. 2. For children, line spacing 0.6mm is best of represent scanimation images.It’s different from adults who just see line spacing 0.3mm, or 0.4mm to build a complete image. 3. Three or four pictures are best number of scanimation images. 4. For the reflection holographic, the bottom of geometry virtual images with 40% luminance and the bottom of geometry real images with 0% luminance are the most clear holographic. And the children prefer to the show of geometry virtual images.
