本文描述了Rasch分析心理测量技术，以及生命科学教育研究人员如何使用此类技术来指导调查和测试的开发和使用。具体而言，Rasch技术可用于记录和评估此类仪器的测量功能。Rasch技术还允许研究人员构建“赖特地图”来解释测试分数或调查分数的含义，并开发测试和调查的替代形式。Rasch技术提供了一种机制，通过该机制可以优化生命科学相关测试和调查的质量，并且该技术可以用于提供上下文（例如，在解释测试和调查结果时，
This essay describes Rasch analysis psychometric techniques and how such techniques can be used by life sciences education researchers to guide the development and use of surveys and tests. Specifically, Rasch techniques can be used to document and evaluate the measurement functioning of such instruments. Rasch techniques also allow researchers to construct "Wright maps" to explain the meaning of a test score or survey score and develop alternative forms of tests and surveys. Rasch techniques provide a mechanism by which the quality of life sciences-related tests and surveys can be optimized and the techniques can be used to provide a context (e.g., what topics a student has mastered) when explaining test and survey results.
