Refining, Operationalizing, and Describing Scientific Inquiry Instructional Practice Using the Inquiry Science Instruction Observation Protocol (ISIOP): A National Field Test

教育发展中心公司提出了一项为期三年的REESE前沿研究实证项目（测量，建模和方法），以开发培训手册并促进研究性科学教学观察协议（ISIOP）的国家现场测试。ISIOP是由美国国家科学基金会资助开发的。拟议的项目将制定观察方案和评分标准，供科学教育评估人员测试使用。该项目的主要目标是改进测量技术和工具，以便通过课堂观察来捕捉科学探究教学中的变化。现场测试将有来自全国不同学校的40名评估专家（20个小组）参加。他们将生成80个成对观测的观测数据集。实地测试将采用分层抽样策略，以最大限度地代表全国各地的学校、教室和学生。该数据集将用于证明科学上合理的有效性论证，支持对评分标准的预期解释，以衡量中年级科学课堂教学中展示的科学探究教学实践的性质和程度。该项目产生的产品包括：(1)观察协议和评分标准，这些协议和评分标准已在各种环境下的一系列科学教育计划评估人员中进行了可用性和实用性测试；(2)用户？该手册清楚地描述了开发过程，可靠性和有效性证据的推导，使用和评分协议的程序信息，使用所包括的教学录像示例建立评分者之间可靠性的指南，以及关于如何协调ISIOP与其他工具的使用以产生综合研究或评估计划的建议。

Project AbstractEducation Development Center, Inc. has proposed a three-year REESE Frontier Research empirical project (Measurement, Modeling, and Methods) to develop a training manual and facilitate a national field test of the Inquiry Science Instruction Observation Protocol (ISIOP). The ISIOP was developed with NSF funding. The proposed project will develop observation protocol and scoring rubrics that will be tested for use by science education evaluators. The main objective of the project is to improve the measurement technology and tools for capturing variation in scientific inquiry instruction via classroom observation. The field test will involve 40 evaluation professionals (20 teams) at different schools across the country. They will generate an observation data set of 80 paired observations. The field test will use a stratified sampling strategy to maximize the representation of schools, classrooms and students across the nation in the study. This data set will be used to demonstrate a scientifically sound validity argument supporting the intended interpretation of the scoring rubrics for measuring the nature and extent of scientific inquiry instructional practices exhibited in middle-grades science classroom teaching. The products generated from the project include (1) an observation protocol and scoring rubrics that have been tested for usability and utility across a range of science education program evaluators in various settings; (2) a user?s manual that clearly describes the development process, the derivation of the evidence of reliability and validity, procedural information for using and scoring the protocol, guidelines for establishing inter-rater reliability using the included videotaped examples of teaching, and suggestions about how to coordinate the use of the ISIOP with other instruments to produce a comprehensive research or evaluation plan.
