大多数生物学本科生在整个大学生涯中都会在多个教室中了解突变。了解个性化基因组测试结果、基因组编辑争议以及病毒新变种或抗生素耐药细菌的出现都需要有关突变的基础知识。然而,围绕突变的分子过程的抽象性质使它们成为学生理解和应用更困难的主题之一。教师需要有效的评估工具来记录学生的理解并调整他们的教学方法以解决学生的知识差距。我们在此描述突变标准参考评估 (MuCRA) 的开发和验证。这种形成性评估是通过迭代过程制定的,涉及专家反馈和学生对开放式问题和多项选择问题的回答。最终的 MuCRA 由 10 个多项选择题组成,与三个学习目标相一致。每个问题的项目难度在 0.32-0.65 之间,辨别指数在 0.31-0.75 之间,MuCRA 的信度 (KR20) 为 0.69。一致性分析表明,干扰因素在 9/10 问题中捕获了学生的误解。这些数据表明 MuCRA 可用于可靠地评估学生的学习情况和对突变的常见误解。
Most biology undergraduates learn about mutations in multiple classrooms throughout their college career. Understanding personalised genome test results, genome editing controversies, and the appearance of new variants of viruses or antibiotic resistant bacteria all require foundational knowledge about mutations. However, the abstract nature of molecular processes surrounding mutations makes them one of the more difficult topics for students to understand and apply. Instructors need valid assessment tools to document student understanding and tailor their instructional methods to address student knowledge gaps. We describe here the development and validation of the Mutations Criterion Referenced Assessment (MuCRA). This formative assessment was developed through an iterative process involving expert feedback and student responses to both open-ended and multiple-choice questions. The final MuCRA is composed of 10 multiple-choice questions aligned with three learning objectives. The item difficulty for each question was between 0.32–0.65, while the discrimination index ranged from 0.31–0.75 and the reliability (KR20) for the MuCRA was 0.69. The congruence analyses demonstrated distractors are capturing student misconceptions in 9/10 questions. These data indicate that the MuCRA can be used to reliably assess student learning and common misconceptions about mutations.
