Exploring the Impact of POGIL on Student Engagement and Conceptual Understanding

该项目旨在通过改善本科STEM教育和确定提高学生参与度的最佳实践来服务于国家利益。大量研究表明，基于证据的教学策略，如过程导向的指导性探究学习（POGIL），可以带来更好的学生成果，从更高的成绩到增加的自我效能感和归属感。研究界才刚刚开始理解为什么POGIL对学生有这些影响，以及POGIL的哪些方面对最大限度地提高学习和其他成果最重要。该项目计划调查教学方法如何影响学生的参与和理解，包括互动讲座（穿插学生活动的讲座）和POGIL。众所周知，参与对学生的学习很重要，但这种参与的性质和程度并没有很好的记录。这两种方法都涉及多种实践，但对于教师使用哪些实践以及对学生学习产生的影响，人们知之甚少。该项目希望确定这些做法如何影响学生的成绩，以及教师如何提高这些成果。本项目拟：(1)考察学生和教师在POGIL活动和互动讲座中参与相关行为的异同；(2)测量课堂观察结果与学生和教师对学生投入的感知之间的同步效度；(3)当使用POGIL活动和使用交互式讲座介绍概念时，寻找学生对概念的理解可能存在的差异。为了探索学生参与与学习之间的关系，pi将使用POGIL或互动讲座来测量同一名教师在不同课堂期间同一名学生的参与程度。通过POGIL与互动讲座介绍概念时，学生的学习情况也将进行分析。学生的参与度将通过三角测量课堂观察与学生和教师的评分来衡量。将开发和管理测验，以衡量不同种类的概念理解。NSF IUSE: EHR计划支持研究和开发项目，以提高所有学生STEM教育的有效性。通过参与学生学习轨道，该计划支持有前途的实践和工具的创建，探索和实施。该奖项反映了美国国家科学基金会的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。

This project aims to serve the national interest by improving undergraduate STEM education and identifying best practices to increase student engagement. Numerous studies have shown that evidence-based teaching strategies, such as Process Oriented Guided Inquiry Learning (POGIL), lead to better student outcomes, from higher grades to increased self-efficacy and sense of belonging. The research community is only beginning to understand why POGIL has these effects on students and what aspects of POGIL are most important for maximizing learning and other outcomes. This project plans to investigate how student engagement and understanding are affected by instructional approaches, including interactive lectures (lectures interspersed with student activities) and POGIL. Engagement is known to be important to student learning, but the nature and extent of this engagement is not well documented. Both approaches involve multiple practices, but not enough is known about which practices faculty use and the resulting impact on student learning. This project hopes to identify how these practices impact student outcomes, and how faculty can enhance these outcomes.This project plans to: (1) Examine similarities and differences in engagement-related behaviors of students and instructors during POGIL activities and interactive lectures; (2) Measure the degree of concurrent validity between classroom observation results and the student and instructor perceptions of student engagement; and (3) Look for possible differences in students' understanding of a concept when it is introduced using a POGIL activity and when it is introduced using an interactive lecture. To explore the relationship between student engagement and learning, the PIs will measure the engagement of the same students in different class periods taught by the same instructor, using either POGIL or interactive lectures. Student learning when concepts are introduced via POGIL versus interactive lectures will also be analyzed. Student engagement will be measured by triangulating classroom observations with student and faculty ratings. Quizzes will be developed and administered that will measure different kinds of conceptual understanding. The NSF IUSE: EHR Program supports research and development projects to improve the effectiveness of STEM education for all students. Through the Engaged Student Learning track, the program supports the creation, exploration, and implementation of promising practices and tools.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
