摘要
这种基于情境的数学问题解决已经被证明对学生的承载量有直接的影响。本研究比较了情境教学法和传统教学法对职业技术学生的认知和情感效果。采用数学问题解决前测和后测测试评估学生的问题解决水平,采用态度、信念和信心(a - b - c)问卷评估高职高专学生的态度、信念和信心。为了进行定性分析,我们分析了学生的日记、访谈回复、教师观察员和评分者的笔记和评论。结果显示,干预前学生的数学分析水平很低,数学内容知识有限。然而,基于情境的方法提高了学生的问题解决能力,表现在数字分数的提高和实验班解决问题的质量的提高以及对问题解决后测的反应。处理后的统计检验显示,情境教学法在方法、程序和能力水平上对高职高专学生的某些数学主题有显著的影响。结果还显示,与对照组相比,实验组在解决数学问题方面的态度和信念有了显著改善。通过项目后测结果比较,理学士学生的整体问题解决得分显著高于工学院学生,实验班的理学士和工学院学生的问题解决得分也显著高于工学院学生。关键词:数学,基于上下文,数学问题解决,态度,信念,信心,voco -tech学生,ililio,菲律宾
Context Based Mathematics Problem Solving: Cognitive and Affective Effects on BIT and BS VOC-Tech Students
This context based Mathematics problem solving has been shown to have direct efforts on students’ bearing. This study compares the cognitive and affective effects of the Context-Based and Traditional approach on voc-tech students from the two programs. Quantitative data were collected using a Pretest and Posttest examination in mathematics problem solving to assess the levels of students’ problem solving performance and an attitude, beliefs and confidence (A-B-C) questionnaire to assess the voc-tech students’ attitude, belief and confidence. For qualitative analysis, the students’ journals, interview responses, and the teacher−observers’ and raters’ notes and comments were analyzed. The results showed that the students have a very low analytic level and limited content knowledge in mathematics prior the intervention. However, the context-based approach enhanced the students’ problem solving skills as exhibited by the numerically higher scores and improvement in the quality of the experimental class’ solutions and responses to the problem solving posttest. After the treatment, statistical tests revealed that the contextbased approach had a significant effect on the voc-tech students on certain topics of mathematics in terms of approach, program and ability level. Results also revealed that the experimental group showed a significant improvement in their attitude and beliefs in mathematics problem solving compared to their counterparts in the control group. Comparing the posttest results by program, the BS students are significantly higher than the BIT students in their overall problem solving scores as well as the BIT and BS students in the experimental class.
