Evaluation of HS Science Courses

本项目将收集证据，支持测试工具的有效性，并初步描述高中教师的背景和使用的材料和方法。 萨德勒博士和他的同事们开发了600多个评估项目，与国家研究理事会的K-12年级物理科学内容标准相匹配。 每个项目都包括一个干扰因素，这些干扰因素是从对物理科学中错误概念的研究文献的广泛回顾中收集的。 有了这一项目级的信息，该项目将构建和验证多种形式的测试工具，可用于评估干预措施（如专业发展、新课程的实施）和衡量教师知识的各个方面（如主题、学生误解的知识）。 这项为期一年的计划的拟议任务是：（1）内容效度研究;（2）试验测试工具的组装;（3）标准参照效度研究;（4）可靠性研究;以及（5）创建教师课程和专业发展调查。 这五项任务将导致高中化学和物理学生的测试仪器和调查，可以记录各种课程，教学方法和高中科学教师的专业发展背景，在未来的日期进行研究。 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计划。

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.
