多頻譜彩色圖文複製技術對色彩感知學習影響之研究

Abstract

近年來，數位化已普遍應用在各學科教學上。美術教育的教學方式也透過數位化之螢幕投影、智慧型手機、平板電腦…等方式觀看繪畫作品。然而不同的螢幕顯色與參差不齊的印刷品，導致色彩差異問題存在於課程教學中，使得學習者在學習美術鑑賞時對作品所呈現的色彩無法直接體會與感受其原色。基於上述現況，本研究透過兩種（多頻譜、RGB）彩色圖文複製教材融入於色彩感知教學實驗中，並依照美術鑑賞理論中所提之「描述」、「分析」、「詮釋」與「判斷」四步驟設計教學課程內容、問卷試題。此外，研究對象則以某所大專院校之美術鑑賞相關課程，共60位學生進行教學實驗，並以隨機抽樣方式從中抽選共14位受訪者進行結構式訪談，深入了解受訪者對兩種教材之色彩品質感受之外，也透過評分方式，具體得知受訪者對兩種教學教材之色彩品質感受為何。 經研究結果顯示，透過兩種（多頻譜、RGB）彩色圖文複製教材進行色彩感知教學實驗後，學習者之前後測學習成就有明顯差異；而且，兩種（多頻譜、RGB）彩色圖文複製教學教材間之學習成就也具有顯著差異。加上色彩品質感受之結構式訪談結果得知，學習者能將色彩感知教學內容運用於鑑賞作品中之外，也表示多頻譜教材色彩呈現更加接近原作品之色彩。因此，多頻譜彩色圖文複製教材對用於色彩感知能力具有正向提升，且高於RGB彩色圖文複製教材；也透過本研究使學習者了解色彩對美術鑑賞的重要性，並提升學習者在鑑賞過程中能更加全面且深入了解作品之含義。

In recent years, digital media have been commonly applied in learning art-related subject matters. These media include digital projectors, smart phones, and tablets, ...etc. However, authentic colors of many art works are likely to be reproduced incorrectly by these digital media. This study used two types of digital color reproduction technologies (Multi-spectral Digital Photography and RGB Digital Photography) to duplicate and reprint artworks as teaching materials for a color appreciation course. This study uses two types of digital color reproduction technologies (Multi-spectral Digital Photography and RGB Digital Photography) to duplicate and reprint artworks as teaching materials for a color appreciation course. Also, the questionnaire and the curriculum are design based on the four steps proposed in Art Appreciation Theory which are “The Description”, “The Formal Analysis”, “The Interpretation” and “The Judgment”, respectively. 60 students are selected in an art appreciation course to perform the teaching experiment. Then, 14 among those 60 students are chosen randomly to conduct a structured interview. Furthermore, a specific evaluation method is applied to quantify the respondents’ perspectives on the color qualities of these two kinds of teaching materials. The experiment results not only show that the learning effectiveness of these students is improved but also show the evident differences between the two kinds of digital teaching materials (Multi-spectral Digital Photography and RGB Digital Photography). In conclusion, Multi-spectral Digital Photography is beneficial for color perception in comparison to RGB Digital Photography. Through this study, respondents can understand the importance of colors towards art appreciations. Most of all, respondents are equipped to comprehend artworks in-depth and realize the implications of each artwork.
