摘要
本研究考察了概念映射和问题解决教学策略对尼日利亚中学生遗传学成绩的影响。本研究采用准实验前测后测处理设计。从尼日利亚三角洲州北三角洲参议院区的三所混合中学随机抽取的113名高中三年级学生作为研究对象。实验组使用概念图和解决问题的策略来教授选定的遗传学主题，而对照组则使用传统的讲座方法进行教学。研究结果表明，实验组的遗传学成绩明显好于对照组，性别对学生的遗传学成绩没有影响。非洲数学与科学教育研究杂志Vol. 4 2006: pp. 93-98
The Effect of Concept Mapping and Problem-Solving Teaching Strategies on Achievement in Genetics among !igerian Secondary School Students
The study examined the effect of concept-mapping and problem-solving teaching strategies on achievement in genetics among Nigerian Secondary School Students. The method used for the study was a quasi-experimental pre-test post-test treatment design. One hundred and thirteen senior secondary three (S.S. III) students randomly selected from three mixed secondary schools located in Delta North Senatorial District of Delta State, Nigeria were used as subjects for the study. The experimental group was taught selected topics in Genetics using concept mapping and problem-solving strategies while the control group was taught using the traditional lecture method. The result of the study showed that the experimental group performed significantly better in Genetics than the control group and that gender does not affect students' achievement in genetics.
