两类教材对初中生数学推理技能影响的比较研究

A Comparative Study on the Impact of Two Kinds of Textbooks on the Deductive Skills of Junior High School Students

使用两类教材的初中生的数学推理技能存在显著差异；使用两类教材的初中生的演绎推理技能存在显著差异；使用两类教材的初中生的合情推理技能没有显著差异。《标准》应坚持“演绎推理与合情推理并重”的思想；对推理能力的定位应更加明确。教材的编写要使形式和内容统一。在教学中要坚持演绎推理与合情推理并重的思想。

Significant differences exist in the mathematics reasoning skills and deductive reasoning skills of the students in junior high schools where two kinds of textbooks are used respectively. However, no significant difference is found in the plausible deductive skills of those students who used the two kinds of textbooks. The Curriculum Standard is supposed to insist on laying equal emphasis on developing students＇ deductive reasoning and plausible reasoning ability, thus the positioning of the skills should be made even clearer. The unity of form and content is crucial in the compilation of textbooks. Both deductive reasoning and plausible reasoning ability should be equally stressed in classroom teaching.
