This article describes the validation of the Science Identities, Expectations of Success in Science, Values of Science, and Environmental Attitudes (SIEVEA) instrument using Rasch analysis. SIEVEA is an online survey that can be used to measure students’ science identities, expectations of success in science, values of science, and environmental attitudes. The instrument was previously validated through exploratory and confirmatory factor analyses. During the current study, 3454 high school students from 13 urban, suburban, and private schools in New Jersey, Pennsylvania, and Connecticut took SIEVEA. The collected data was analyzed using Rasch analysis. The results of the analysis once again confirmed the instrument’s reliability and validity. The SIEVEA instrument is a valuable tool, which allows for measurement of important constructs related to successful science learning.

本文介绍了使用Rasch分析验证科学身份，科学成功期望，科学价值和环境态度（SIEVEA）仪器的有效性。SIEVEA是一项在线调查，可用于衡量学生的科学身份，对科学成功的期望，科学价值观和环境态度。该仪器先前已通过探索性和确认性因素分析得到了验证。在当前的研究中，来自新泽西州，宾夕法尼亚州和康涅狄格州的13所城市，郊区和私立学校的3454名高中学生参加了SIEVEA。使用Rasch分析来分析收集的数据。分析结果再次确认了仪器的可靠性和有效性。SIEVEA工具是一种有价值的工具，
