Evaluation of HS Science Courses

该项目将收集证据，支持测试工具的有效性，并初步描述高中教师的背景以及材料和教学方法的使用。萨德勒博士和他的同事已经为K-12年级开发了600多个与国家研究委员会的物理科学内容标准相匹配的评估项目。每一项都包括一个干扰因素，从广泛的研究文献中收集，报告了物理科学中的错误概念。利用这一项目级信息，该项目将构建和验证多种形式的测试工具，这些工具可用于评估干预措施(例如，专业发展、实施新课程)和衡量教师知识的各个方面(例如，主题、学生误解的知识)。这个为期一年的项目的拟议任务是：1)内容效度研究；2)试测工具的组装；3)参照标准的效度研究；4)可靠性研究；以及5)创建教师课程和专业发展调查。这五项任务将为高中化学和物理学生提供经过充分验证的测试工具，并将在未来研究一项调查，该调查可以记录高中科学教师的各种课程、教学方法和专业发展背景。这些经过充分验证的工具也将提供给其他研究人员，以帮助他们评估具体的干预措施或方案。

This project will collect evidence supporting the validity of test instruments and initial characterization of high school teachers' background and use of materials and pedagogies. Dr. Sadler and his colleagues have developed more than 600 assessment items matched to the National Research Council's Physical Science Content Standards for grades K-12. Each item includes a distractor gleaned from an extensive review of research literature reporting on misconceptions in the physical sciences. With this item-level information, the project will construct and validate multiple forms of test instruments that can be used for the evaluation of interventions (e.g. professional development, implementation of new curricula) and the measurement of aspects of teacher knowledge (e.g. subject matter, knowledge of student misconceptions). The proposed tasks for the one-year project are: 1) a content validity study; 2) the assembly of trial test instruments; 3) a criterion referenced validity study; 4) a reliability study; and 5) the creation of a teacher curriculum and professional development survey. These five tasks will result in well-validated test instruments for high school chemistry and physics students and a survey that can document the variety of curricula, pedagogical approaches, and professional development backgrounds of high school science teachers to be researched at a future date. These well-validated instruments will also be made available to other researchers to aid in their efforts to evaluate specific interventions or programs.
