Abstract

Content validity is useful for testing the suitability of test items with the materials and capabilities to be measured. This validity is done by testing the feasibility of the instrument through panel discussions by experts who are competent in their fields. In this study, content validity was applied to the computerized testlet instrument. Computerized testlet is a group of multiple-choice items to reveal the same information developed in a computerized system. The computerized testlet instrument in this study consists of sevens stem (the subject matter), each of with consists of three interrelated multiple-choice questions. This computerized testlet instrument was validated by nine raters consisting of three chemistry education experts, three chemistry teachers, and three chemistry education students. The validation was done by referring to the assessment of five aspects including the aspects of scientific competence, science subject knowledge, question context, spelling and language, and clarity of th...

内容效度采用计算机化测试仪器的Rasch模型来衡量化学素养能力

内容效度对于测试项目与要测量的材料和能力的适用性是有用的。这种有效性是通过由在各自领域有能力的专家进行小组讨论来测试该工具的可行性来实现的。本研究将内容效度应用于电脑测试仪器。计算机测试是一组多项选择题，显示与计算机系统相同的信息。本研究的计算机测试工具由七个部分(主题)组成，每个部分由三个相互关联的选择题组成。由3名化学教育专家、3名化学教师和3名化学教育学生组成的9名评判员对该计算机化测试仪器进行了验证。通过对科学能力、科学学科知识、问题语境、拼写和语言以及问题的清晰性五个方面的评估来进行验证。
