摘要

本研究目的旨在發展具信效度之物質微粒特性概念理解層次評量工具，做為評量大學生化學平衡試題理解層次之診斷，以了解學生對試題概念理解程度之分布，並分析不同背景變項學生對理解程度的影響。以SPSS統計分析法，分析173位學生的理解程度之分布，研究結果有：（1）從評分者間信度，發現和諧係數W=0.61，p＜.05具顯著水準，顯示3位評分者一致性信度良好；（2）理解程度之分布，發現有61.8%的大學生理解程度屬於程度1和程度2。從物質微粒特性概念理解，發現改善化學教學策略是未來努力的重點方向。

This study evaluated 173 university students' different understanding levels on their conceptions of the particulate nature of the matter. To develop an assessing tool with high validity and reliability to evaluate macroscopic, symbolic and microscopic conception of students' understanding levels for the particulate nature of the matter in chemistry equilibrium. This study applied SPSS statistic method to analyze students' understanding levels. There were two dynamic results to show in the following. Firstly, there were 3 reviewers to present substantial inter-rater reliability which Kendall's coefficient of concordance was 0.61 with significant level p＜.05. Secondly, 61.8% university students' understanding levels present low level 1 and level 2. It would be expected that the struggles of the improve chemistry instruction strategy for their concept understanding of the particulate nature of the matter in the future.
