Quantifying the Extent of Student Learning and Affect Associated with Observed Levels of Instructional Reform

本计画旨在量化教学活动、学生学习、学生态度与兴趣之间的关系，以服务国家利益，使教师能在教学实践中作出明智的决定。许多研究报告称，主动学习策略，也被称为以学生为中心的教学，支持学生在科学课程中取得成功，但没有量化的衡量方法来衡量不同程度的以学生为中心的教学对学生学习的影响。这个IUSE Track 1 Engaged Student Learning Level 2项目将满足这种量化的需求。更好地理解这些关系将反过来使科学教师能够对他们的教学实践进行基于数据的修改，以最好地支持学生的学习。该项目的目标是将学生的学习和兴趣与不同程度的改革教学实践联系起来。该项目将根据改革后的教学观察协议（RTOP）和本科STEM课堂观察协议（COPUS）设计一系列以教师为中心/教学、过渡/互动讲座和以学生为中心的地球科学入门课程。RTOP和COPUS是用来衡量教师教学方法和学生参与STEM课堂的工具。治疗课程将在四个不同机构的多个学期的课程中分散进行，以便每个机构的学生在每个改革教学水平的每个课程中至少体验一次。一系列的概念评估和学生兴趣问题将衡量学生的学习、学生对学习的感知和学生的兴趣。使用RTOP和COPUS协议的观察将衡量治疗班和非治疗班以学生为中心的教学实践的程度。人口统计学数据将用于评估不同程度的以学生为中心的教学是否对具有不同人口统计学特征的学生的学习、学习感知或兴趣有任何不同的影响。该项目将使用模型选择方法来确定哪些因素（以学生为中心的教学程度、学生兴趣、学生对学习的看法、人口因素）最能预测学生的学习成果。该项目的成果将是一个模型，该模型描述了不同程度的以学生为中心的教学如何影响学生的学习。通过将学生人口统计学与学习和情感相结合，这项工作将产生新的信息来描述传统少数群体学生的学习和情感特征，并将提供一个框架，教师可以使用该框架来确定他们希望采用的基于提高学生成功的明确目标的教学实践。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。通过其参与学生学习轨道，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 quantifying the relationship among teaching activities, student learning, and student attitudes and interests so that instructors can make informed decisions about their teaching practices. Many studies report that active learning strategies, also known as student-centered teaching, support student success in science courses, but there is no quantitative measure of how much student learning changes with different degrees of student-centered teaching. This IUSE Track 1 Engaged Student Learning Level 2 project will fill this need for quantification. Better understanding of these relationships will in turn allow science instructors to make data-enabled modifications to their teaching practices to best support student learning.The goal of this project is to correlate student learning and interest with different degrees of reformed teaching practices. The project will design a series of introductory geoscience lessons that can be classified as teacher-centered/didactic, transitional/ interactive lecture, and student-centered based on the Reformed Teaching Observation Protocol (RTOP) and Classroom Observation Protocol for Undergraduate STEM (COPUS) classroom observation protocols. RTOP and COPUS are tools used to measure faculty teaching methods and student engagement in STEM classrooms. The treatment lessons will be interspersed in classrooms at four different institutions over the course of multiple semesters so that students at each institution experience each lesson at each level of reformed teaching at least one time. A series of conceptual assessments and student interest questions will measure student learning, students’ perception of their learning, and student interest. Observations using the RTOP and COPUS protocols will measure the degree of student-centered teaching practices in both treatment and non-treatment classes. Demographic data will be used to assess if different degrees of student-centered instruction have any differential impacts on the learning, perceptions of learning, or interest for students with different demographic characteristics. The project will use a model selection approach to determine which factors (degree of student-centered teaching, student interest, student perceptions of learning, demographic factors) best predict student learning gains. The outcomes of this project will be a model that characterizes how student learning scales with different degrees of student-centered teaching. By integrating student demographics with learning and affect, this work will generate new information to characterize learning and affect for students from traditionally minoritized groups and will provide a framework that faculty can use to determine instructional practices they wish to adopt based on a clear target for improved student success. The NSF IUSE: EHR Program supports research and development projects to improve the effectiveness of STEM education for all students. Through its 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.
