从科技竞赛获奖作品分析化学研究性学习选题的科学性

Analysis of Scientificality of Research-Based Learning Topics on Chemistry from Perspective of Award-Winning Works in Science and Technology Competition

统计分析了近11届(2007-2017年)全国青少年科技创新大赛中化学参赛项目以及荣获一等奖的项目在化学二级学科中的分布情况,结果显示:涉及交叉学科的材料化学专业获奖项目数量和质量占据的比例越来越大,有机化学和物理化学也是中学生探究课题的热门方向,获奖项目数量仅次于材料化学。基于分析数据,总结了各二级学科中学生选题较为集中的研究领域,并对教师指导学生开展研究性学习选题的思路和方法提出了建议。

This paper statistics and analyses the distribution of the chemical subjects in the national youth science and technology innovation competition in the nearly eleven sessions(2007-2017) and the first prize winners in the second-level chemistry disciplines. The results show that the number and quality of award-winning projects in materials chemistry specialty are increasing;organic chemistry and physical chemistry are also hot topics for high school students to explore, the number of award-winning projects is second. Based on the data analysis, this paper summarizes the research fields in which the subjects selected by the high school students are more concentrated, and puts forward some suggestions on the ideas and methods for teachers to guide students to carry out research-based learning.
