Sam McKagan, Editor, PER User's Guide - American Association of Physics Teachers
Physics education research (PER) is widely recognized as a leader in discipline-based science education research. Researchers in the field of PER have made enormous advances in understanding how students learn physics most effectively and in developing teaching methods that dramatically improve student learning.1 However, research on faculty change has found that even educators who know about PER and are highly motivated to improve their teaching have trouble finding the information they need to implement PER-based teaching methods effectively.2 The PER User's Guide is a growing web resource designed to address this problem by translating, summarizing, and organizing the results of PER in an accessible and useful way for busy educators. The American Association of Physics Teachers (AAPT) has developed a pilot site with NSF funding in conjunction with the ComPADRE digital library, with the PER Leadership and Organizing Council (PERLOC) serving as the advisory board.
The content of the PER User's Guide has been developed by the editor based on classroom observations, interviews with developers and adopters of PER-based teaching methods, surveys, and literature reviews. One important result that has come out of this work is that curriculum developers have many hidden assumptions based on their own environments and goals, and thus are not always able to effectively communicate the essential features of their curricula to adopters. Successful adopters, on the other hand, because they have had to struggle with enacting someone else's vision in a new environment, are often able to articulate these hidden assumptions and to offer much more detailed and clear advice for other adopters. This result suggests that the current practice of leaving dissemination to curriculum developers is not the best way to increase effective implementation. The PER User's Guide is playing an important role in dissemination by collecting the wisdom of successful adopters that has traditionally been left untapped.Some of the features available on the PER User's Guide include:
User testing with physics faculty has shown that the site is easy to navigate and provides many resources that faculty need, and has highlighted many areas for further development and expansion. In addition to providing basic overviews of PER-based teaching methods for instructors who are still trying to decide which method to use, we are developing detailed implementation guides to provide comprehensive guidance for instructors who are already working on implementing a particular method. Each detailed implementation guide will contain approximately 20 pages of text, graphics, and multimedia, demonstrating the method through detailed suggestions for implementation, ways to address common challenges and questions, a summary of the research base behind the method, classroom videos, reviews by other adopters, case studies of successful adopters, and ways to connect with other adopters.The next step in the development of the PER User's Guide, funded by a new NSF grant, will be the development of assessment resources. The PER community has produced dozens of researchvalidated assessment tools to evaluate the effectiveness of different teaching methods for many different physics topics. These assessment tools have had a major impact on physics education reform: The Force Concept Inventory (FCI)3 a test of basic concepts of forces and acceleration, has been given to thousands of students throughout the country and the results show that PERbased teaching methods lead to dramatic improvements in students' conceptual understanding of mechanics. These results have inspired many physics instructors to try the FCI with their own students and to radically change their teaching methods based on the results. Similar assessments exist in nearly every topic in physics, but it is often difficult for instructors to access these assessments or to interpret the results. We will address this problem by creating a database of assessment tools and results where instructors can access assessment tools, find descriptions of how to use them and the research behind them, and submit student scores to a national database so that other instructors can see typical scores that they can use to evaluate and interpret results from their own classes. This will provide a basis for comparison between instructors and pedagogies that will enable instructors to assess the effectiveness of their instruction on a variety of topics, promoting the adoption of more effective teaching methods. In addition, we will provide overviews for faculty on a variety of research-based assessments in their classrooms. These overviews will cover a range of types of assessment, including summative, formative, and programmatic. Future goals for the PER User's Guide include:
