初一学生数学学习的学科领域知识表征特点

The Features of Disciplinary Domain Knowledge Representation in Mathematics Learning of Grade One Students in the Junior High School

学科领域知识由学理内容知识、认知过程知识和问题条件知识组成。本研究以529名七年级学生为被试,测查学生在数学学习中的学科领域知识表征特点,结果发现:(1)三种类型知识表征存在显著差异,学理内容知识表征水平最高,问题条件知识表征水平最低;(2)学优生的学科领域知识表征水平显著高于中等生和学困生;(3)认知过程知识表征、问题条件知识表征水平与数学学业成绩显著相关;(4)学生对学理内容知识重要性评价最高,问题条件知识最低。

Disciplinary domain knowledge is composed of the scientific content knowledge, cognitive process knowledge and problematic condition knowledge. 529 seven grouders in junior high school were tested to investigate the representational feature of disciplinary domain knowledge in mathematics with questionraires. The study found that： （1） There are significant differences in three types of knowledge representation level. The representational level of scientific content knowledge is the highest, while the representational level of problematic conditions knowledge is the lowest; （2） The representation level of excellent students in disciplinary domain knowledge are significantly higher than the average students and inferior students; （3） The representational level of cognitive process knowledge and problematic condition knowledge are significantly related to mathematics performance; （4） Students give higher ap- praisal to the importance of scientific content knowledge, but lower to the problematic condition knowledge.
