摘要
本文采用MAS法和CTA法,以中学化学的离子反应内容为载体,完成30个典型试题绝对难度的两次标定。继而从转换维度、编码、MAS绝对难度三个角度分别对两次标定的绝对难度进行相关分析。研究结果表明:采用MAS法和CTA法标定试题绝对难度具有较高的一致性。
The absolute difficulties of 30 typical ion reaction problems are calculated with MAS and CTA. The relationships between these two difficulties are analyzed in detail based on three aspects： the transformation dimensions, MAS coding numbers and the value of absolute difficulties. The results of this study suggest that both of the two methods are in high coherence.
