美国学生在数学和科学方面的国际竞赛和测试中几乎垫底。人们认为，家庭、社区和学校等外在因素可能比对科学兴趣的内在态度更有影响力。然而，对诸如与科学相关的兴趣等内在因素的有效和可靠的衡量标准相对较少。由于缺乏内在措施，很难确定外在因素对内在结构的影响。更全面地了解影响科学兴趣等内在因素的因素将使干预措施变得更加精细和有针对性。多项研究表明，学生对科学的兴趣会影响学生学习高级科学课程的可能性。本文的目标是确定科学兴趣调查的有效性和可靠性，并确定该调查是否满足 Rasch 模型定义的测量的形式要求。使用 IRT 和 CRT 分析的结果表明，科学兴趣调查是对被称为科学兴趣的一维结构的充分衡量。结果进一步表明，科学兴趣调查是评估科学兴趣水平的有效且可靠的措施。
Students in the USA have fallen near the bottom in international competitions and tests in mathematics and science. It is thought that extrinsic factors such as family, community, and schools might be more influential than intrinsic attitudes toward science interest. However, there are relatively few valid and reliable measures of intrinsic factors such as interest relating to science. With the lack of intrinsic measures, it is difficult to determine the impact of extrinsic factors on the intrinsic construct. A fuller picture of the factors affecting intrinsic factors such as science interest will allow interventions to become more refined and targeted. Several studies suggest that student interest toward science affects the likelihood of the student pursuing advanced courses in science. The goal of this paper is to establish the validity and reliability of the Science Interest Survey and to determine if the survey meets the formal requirements of measurements as defined by the Rasch model. Results using both IRT and CRT analysis suggest that Science Interest Survey is an adequate measure of the unidimensional construct known as science interest. Results further suggest the Science Interest Survey is a valid and reliable measure for assessing science interest levels.
