听障初中生数学概念学习策略研究

A Study of the Effectiveness of the Learning Strategies of Mathematic Concepts for Hearing-impaired Students at Junior High Schools

目的探索听障初中生数学概念学习策略的功效。方法采用促进数学概念学习策略，对12名听障初中生进行为期1学年的数学教学干预。采用问卷调查法分析其心理变化，并对比分析其数学期末统考成绩。结果①实验前后听障初中生数学概念学习问卷调查结果有明显变化，实验后心理倾向“有（能）”的人数比实验前有所增加；②实验后学生数学统考选择题、填空题、求解题得分率逐步提高；③实验后学生统考成绩均分显著上升，及格率提高42％后保持100％。结论数学概念学习策略让听障初中生对数学概念学习的心理倾向产生积极变化，数学成绩显著提高。

Objective To study the effectiveness of the learning strategies for mathematic concepts for hearing-impaired students at junior high schools. Methods The learning strategies for mathematic concepts were used to provide intervention for 12 hearing-impaired junior high school students for one year.The questionnaire survey was conducted to analyze the mental status of students and compare the academic performance in mathematics before and after the intervention. Results （1） After the experiment, the number of the students who choose ＂yes or can＂ in the questionnaire about learning strategies for mathematic concepts increased. （2） After the experiment,the scores of students in the choice questions, completion questions and calculating questions gradually increased. （3） After the experiment, the average scores of these students in the unified examinations increased dramatically. The pass rate increased by 42% and remained 100%. Conclusion The study indicates that the learning strategies for mathematic concepts for hearing-impaired students can have positive effects on the mental status of students. These strategies will be helpful in improving their academic performance and promoting the learninQ of mathematic concepts for hearina-imDaired students.
