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

项目摘要教育发展中心，公司。提出了一个为期三年的REESE前沿研究实证项目（测量，建模和方法），以开发一个培训手册，并促进全国实地测试的探究科学教学观察协议（ISIOP）。ISIOP是在NSF的资助下开发的。拟议的项目将制定观察协议和评分规则，供科学教育评估人员使用。该项目的主要目标是改善测量技术和工具，通过课堂观察捕捉科学探究教学的变化。实地测试将涉及全国不同学校的40名评估专业人员（20个团队）。他们将生成一个包含80个配对观测的观测数据集。实地测试将采用分层抽样策略，以最大限度地提高全国各地学校、教室和学生在研究中的代表性。这个数据集将被用来证明一个科学合理的有效性参数支持预期的解释的评分标尺测量的性质和程度的科学探究教学实践中表现出中年级科学课堂教学。该项目产生的产品包括（1）观察协议和评分规则，这些规则已经在各种环境中的一系列科学教育项目评估人员中进行了可用性和实用性测试;（2）用户？的手册，清楚地描述了开发过程中，可靠性和有效性的证据的推导，程序信息使用和评分的协议，建立评分员之间的可靠性使用包括教学录像的例子，并建议如何协调使用ISIOP与其他工具，以产生一个全面的研究或评估计划的指导方针。

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.
