摘要

本研究為促進專題學習中的知識整合編製一個網路學習環境量表，量表的構念分成易取、互動、反應、結構及整合五個分量表，用以評鑑網路學習環境的設計。研究者請兩位數位學習及一位課程教學專長的大學教授進行該量表初稿的審議，以增加量表的專家效度。由於當前大專進行網路學習的學生樣本不易取得，本研究立意選取研究者運用專題學習策略教授的大專生進行施測。預試施測的回收有效樣本為187份，經項目分析保留網路學習環境量表共39題。正式施測的回收有效樣本為176份，運用結構方程模式以題目分群方式進行驗證性因素分析檢驗該量表的構念效度。結果發現測量模式與觀察資料適配度大致良好。該量表整體信度為.962，各分量表的信度（Cronbach's alpha 值）介於.769至.901 之間。另外，網路學習環境量表設計有開放式問題，藉以蒐集學習者對網路學習環境的感知。經文本分析結果發現，學習者對網路學習環境使用原因及優缺點的感知，會考量易取、互動及整合的特性。本研究發展的網路學習環境量表具有良好的信效度，配合開放式問題文本分析結果的檢驗，確實可作為評鑑網路學習環境的工具。

The purpose of this study was to develop a web based learning environment instrument using insights gained from project based learning and knowledge integration. The instrument contained five subscales: access, interaction, response, structure and integration and was used to evaluate the design of the web based learning environment to promote the knowledge integration of project based learning. In order to enhance the validity of this instrument, two e-learning experts and one course instruction expert were invited to review the instrument. Due to the limitations of web based courses at the college level, data were gathered from college students in a project based course taught by one of the authors with project based learning. The initial number of subjects for the pre-test was 187, and the final version of the instrument contained 39 items. The number of subjects in the post test was 176; using the confirmatory factor analysis to establish construct validity of the instrument with the structured equation model using the item parcels method. By utilizing confirmatory factor analysis to examine the measurement model, goodness of fit was confirmed to be reliable. The Cronbach's alpha reliability for the entire instrument was .962 and the Cronbach's alpha reliability for each of the 5 subscales ranged from .769 to .901. We also designed five open-ended questions for the instrument to collect the subjects' awareness and preferences of the web based project learning environment. The results of content analysis found that; the accessibility, interaction and integration characteristics were the main concerns of the learners in using a web course. Findings of this study confirmed the validity and reliability of the web based learning environment instrument. Thus, showing that it is a useful instrument to evaluate web based learning environments.
