數學能力是日常生活中相當重要的一部分,從小就需要開始培養。近年來,數位遊戲式學習(Digital Game-based Learning, DGBL)已逐漸被應用於教育上,本研究主要是基於DGBL,設計一套在3D虛擬環境Second Life上的數學單元練習遊戲,我們利用「個案研究」的方式,在台灣北部某國小進行實驗。實驗目的是要探討本系統對於資源班學生的數學學習動機及學習成效是否提升,並調查學生使用後的滿意度。實驗結果顯示,透過3D虛擬環境Second Life結合DGBL,能提升學生的學習動機且對學習成效有正面的影響。 Mathematical ability is very important in daily life, it need to start training begin early age. In recent years, Digital Game-Based Learning(DGBL) has been increasingly used in education, this study is based on DGBL, design a digital math game in Second Life, and we use ‘Case Study’ as the theme, experiment at elementary school in northern Taiwan. Purpose of the experiment was to investigate the system for learning motivation and learning outcomes of resource class students, and to investigate the students' satisfaction after use. Experimental results show that combination of Second Life and DGBL can enhance students' learning motivation and learning outcomes.
