摘要
基于FLOWMAP测查高二学生"卤代烃"认知结构, 并采用学科核心素养探究学生"卤代烃"学习困难.研究表明, 学优生认知结构的优势体现在较高的认知"整合度"和准确率, 学困生的劣势体现在较低的信息检索效率, 学优生更善于运用描述及情境推理等信息处理策略建构知识.学生达到不同素养水平的学业要求差异较大.学习困难主要有不知道卤代烃的分类及物理性质, 不明白或混淆发生取代反应与消去反应的特征、条件等, 不知道卤代烃的用途.
Abstract
Based on the FLOWMAP, this paper measured senior two students' cognitive structure, discipline core competencies and learning difficulties with "halogenated hydrocarbon"as an example.Research showed that the advantage of excellent students cognitive structure was reflected in the higher degree of"integration"and accuracy, the disadvantage of students with learning difficulties was reflected in the low efficiency of information retrieval, and excellent students were better at using information processing strategies such as description and situational reasoning.Students differed greatly in their academic requirements for achieving different levels of literacy in halogenated hydrocarbon knowledge system.Learning difficulties mainly included:did not know the classification, physical properties and use of halogenated hydrocarbon, did not understand or confuse characteristics and conditions of substitution reaction and elimination reaction.
