第五章 結論與建議

第三節 研究限制

本研究已在研究架構、研究方法、資料處理與統計分析上力求嚴謹,並且符 合學術規範,但是仍然有研究上的限制,如下所示。

一、研究推論的限制

本研究因空間與人力因素,研究對象採取便利抽樣,而且僅限於臺北地區 B 國中 7 年級參與本課程的學生,故推論具有侷限性,研究結果無法應用至所有年 齡層學生。其次,由於採用自陳式量表回收問卷,非使用精密儀器測量專注程度,

較無法反應受試者真正的情況,因此亦無法得知科學數值與自我陳述之間的誤差

值。第三,本研究非採用縱貫研究進行,雖然所有研究假說獲得驗證,但僅為暫 時性答案,這是因為人的行為與知覺會隨著時空環境而有所改變,因此無法類推 到長期沉浸於擴增實境學習環境的情況之中。

二、系統設計的限制

為配合國中電腦教室的設備與成本考量,因此本擴增實境學習系統是以網站 的形式來呈現,並以電腦螢幕作為擴增實境的顯示方式,未能以其他形式的系統 架構進行開發。而在教材內容方面也聚焦於數位單眼的基礎攝影知識架構,但此 知識架構並未包含所有攝影知識。而在用字遣詞方面,也盡量符合國中學生的理 解程度。另外,基於現實考量,本課程實施時間僅為二堂課(共計 90 分鐘),因 此亦會造成研究結果的限制。

三、研究變項的限制

雖然本研究已在研究設計上盡力排除其他因素影響研究結果,但仍有相當多 的因素是足以影響學生使用擴增實境進行學習的接受度,如學生的個人因素、學 習教材設計、老師個人特質等,以及學生接觸到新教學媒體所產生「新奇效應」

的內在特質,因此不能完全排除這層面的影響。
