摘要

目前行動裝置及數位3D電腦應用發展快速，教育學者也盡力於研究及不斷提升各種應用，以促進電子學習 (e-learning)和行動學習 (mobile learning)，在台灣教育高級職業學校裡機械、設計、土木學群的必修科目中，學生必須學習製圖相關課程，以建立空間概念。雖然已有許多學術研究探討過並且採用正投影作為學習工具主題，本研究主要探討利用開發APP原型來幫助空間概念的學習及相關的教學議題和未來發展。
從相關文獻得知目前正投影教學是可以運用現代科技幫助學生培養空間概念，因此，我們透過ADDIE模型開發一個基於3D APP原型應用於行動學習，此APP學習工具將3D物件整合於行動裝置並以動態3D呈現，APP的原型方便於學生操作切換與觀察等角視圖，進而培養解決空間問題並建立推測多視角圖（又稱三視圖）之能力，系統原型的開發使用一些軟體，如3Ds Max建立3D模型、使用Unity 3D整合以建立3D APP幫助使用者在正投影視圖的操作與互動，為了使該系統更有樂趣，該系統也提供遊戲式的探索與挑戰，本原型已經成功地發佈在Android的平板電腦與智慧手機等行動裝置。本研究邀請高中一年級（十年級生）69位學生作測驗，測試結果令人鼓舞，受測者的問卷回饋也被收集成未來原型改進的依據，這些回饋將可作為未來更詳盡及大規模的可用性測試。

The rapid development of mobile and digital 3D technology has reshaped many current computer applications. Researchers have put great endeavors to continuously explore various approaches to develop applications for promoting e-learning (electronic learning) and mobile learning. Students in various disciplines of vocational high school such as architecture, machinery or visual media design, need to study spatial concepts by taking relevant graphics-related courses. However, the instructional tools for pedagogy, though vividly explored in many researches, are subjected to the users’ adoption of these learning tools. This research aims to investigate the pedagogical issues and henceforth develops an App prototype to help the learning of spatial concepts.
We began with the reviewing of the current status of the pedagogy of orthographic projection and potential technology for supporting the development learners’ spatial concepts’. Based on these efforts, we build a 3D-based App prototype for mobile learning according to the ADDIE model. The App’s learning tools are the integration of 3D tools on mobile devices to dynamically present 3D views of fundamental solid objects. The prototype facilitates students’ manipulation and observation of isometric view and through the reverse problem-solving to build the ability to infer multi-view. The system prototype uses 3Ds Max for constructing solid models. Unity 3D is employed to facilitate the manipulation of orthographic projections and the Unity 3D is used for the integration of these components into a 3D App to help students interact with the orthographic projection of the object. To add more fun in using the system, we provide game-like stages for learners to explore and conquer. The prototype has been successfully deployed on tablet computers and Android-based smartphone systems. We have also recruited several targeted users, i.e. students from tenth grade classes, 69 students to do field test. These users’ responses are encouraging and their feedbacks from the test are collected as the basis for the refinements of the prototype. These improvements of the prototype will serve as the foundation of a more elaborated and larger scale usability test.
