Abstract

Genetics as a core concept of life science is essential for understanding biology. Examining genetics understanding among biology majors is becoming important since they must necessarily achieve some level of genetics understanding to advance their career. This study compares Indonesian biology majors’ genetics understanding with previously published data from students in the United States (US). This study also identifies the effect of academic year and program on genetics understanding by administering the Genetics Concept Assessment (GCA) to 377 biology majors in Indonesia. IRT-Rasch modeling was performed for instrument validation, followed by one-way ANOVA and independent sample t-test for the analysis. The results showed that Indonesian biology majors’ genetics understanding was significantly affected by academic year but was not affected by the academic program. Indonesian biology majors had a slightly similar level of genetics understanding with US non-majors’ pre-test scores, while Indonesian biology majors’ scores were two times lower than US majors’ post-test scores. The implications of reducing the gap between two countries are discussed.
印尼和美国生物学本科学生的遗传学概念理解
遗传学是生命科学的核心概念,是理解生物学的基础。检查生物学专业学生对遗传学的理解变得越来越重要,因为他们必须达到一定程度的遗传学理解才能促进他们的职业发展。本研究比较了印尼生物学专业学生对遗传学的理解与美国学生先前发表的数据。本研究还通过对印度尼西亚377名生物学专业学生进行遗传学概念评估(GCA),确定了学年和课程对遗传学理解的影响。采用IRT-Rasch模型进行仪器验证,然后采用单因素方差分析和独立样本t检验进行分析。结果表明,印尼生物专业学生对遗传学的理解受学年的影响显著,但不受专业的影响。印尼生物学专业学生对遗传学的理解水平与美国非专业学生的测试前得分略有相似,而印尼生物学专业学生的得分比美国非专业学生的测试后得分低两倍。讨论了缩小两国差距的意义。
