继续强调增加和改进K-12年级、医疗专业人员和普通公众的遗传学教育。另一个关键受众是生物学和遗传学入门课程的本科生。为了改进遗传学的学习，有必要首先评估学生对遗传学概念的理解和他们的遗传学素养水平(即与他们的生活相关并影响他们生活的遗传学知识)。我们开发并评估了一种新的工具，用于评估参加生物学入门课程或遗传学课程的本科生的遗传学素养。遗传学素养评估工具是一项包含31个项目的多项选择测试，涉及17个被确定为遗传学素养核心的概念。这些项目是在25名遗传学专业人士和教育工作者的评论的基础上选择和修改的。该仪器在学生焦点小组和试点测试中进行了额外的分析。它已经在8门非专业生物学和遗传学入门课程中接受了近400名学生的评估。考察了量表的内容效度、区分效度、内部信度和稳定性。该项目直接加强了遗传学教育研究，为评估本科生的遗传学素养提供了一个有效和可靠的工具。
There is continued emphasis on increasing and improving genetics education for grades K-12, for medical professionals, and for the general public. Another critical audience is undergraduate Students in introductory biology and genetics courses. To improve the learning of genetics, there is a need to first assess students' understanding of genetics concepts and their level of genetics literacy (i.e., genetics knowledge as it relates to, and affects, their lives). We have developed and evaluated a new instrument to assess the genetics literacy of undergraduate students taking introductory biology, or genetics courses. The Genetics Literacy Assessment Instrument is a 31-item multiple-choice test that addresses 17 concepts identified as central to genetics literacy. The items were selected and modified on the basis of reviews by 25 genetics professionals and educators. The instrument underwent additional analysis in Student focus groups and pilot testing. It has been evaluated using similar to 400 students in eight introductory nonmajor biology and genetics courses. The content validity, discriminant validity, internal reliability, and stability of the instrument have been considered. This project directly enhances genetics education research by providing a valid and reliable instrument for assessing the genetics literacy of undergraduate Students.
