越来越多的研究记录了本科生研究经历的积极成果，包括对科学的坚持。对本科生实验室学习经验的研究表明，经验的设计影响学生报告项目所有权的程度，项目所有权是学生保留科学的心理社会因素之一。迄今为止，衡量项目所有权的方法不适合收集较大的数据集。目前的研究旨在通过开发，介绍和评估一种新的工具来衡量项目所有权，以纠正这一点。根据先前的研究和与项目所有权相关的理论生成了18个缩放项目，并结合了30个项目来衡量受访者对体验的情绪，从而形成了项目所有权调查（POS）。分析POS以确定其维度、信度和效度。POS的系数α为0.92，因此具有较高的内部一致性。已知群体的有效性进行了分析，通过仪器的能力，以区分学生谁在传统的研究为基础的实验室课程。POS规模之间的组和调查结果的区别与以前的结果有关的项目所有权的特点。
A growing body of research documents the positive outcomes of research experiences for undergraduates, including increased persistence in science. Study of undergraduate lab learning experiences has demonstrated that the design of the experience influences the extent to which students report ownership of the project and that project ownership is one of the psychosocial factors involved in student retention in the sciences. To date, methods for measuring project ownership have not been suitable for the collection of larger data sets. The current study aims to rectify this by developing, presenting, and evaluating a new instrument for measuring project ownership. Eighteen scaled items were generated based on prior research and theory related to project ownership and combined with 30 items shown to measure respondents' emotions about an experience, resulting in the Project Ownership survey (POS). The POS was analyzed to determine its dimensionality, reliability, and validity. The POS had a coefficient alpha of 0.92 and thus has high internal consistency. Known-groups validity was analyzed through the ability of the instrument to differentiate between students who studied in traditional versus research-based laboratory courses. The POS scales as differentiated between the groups and findings paralleled previous results in relation to the characteristics of project ownership.
