Students who take lab courses engage in active, collaborative learning that has the potential to teach scientific thinking skills while also stimulating students’ interest in science. In order to understand the impact of collaboration on student learning and experiences in introductory labs, we surveyed more than 450 college physics students about their beliefs and experiences regarding working with a lab partner. While students want a “fair split” of the work, they learn most when they participate equally in all aspects of the lab. Thus, lab courses should be designed to ensure that students participate equally, rather than just splitting up the work.

Two wheeled carts are identical except that one has its wheels taped so that it slides on them with kinetic friction. The other cart rolls frictionlessly. Both carts are placed at the bottom of identical side-by-side rails and propelled up them using identical spring launchers. The carts turn around and return to their starting location. Which gets back first? Or is it a tie? Video of an experimental demonstration will be shown, along with theory and computer simulations, to explain the interesting results.

The Fundamentals of Engineering for Honors program at The Ohio State University actively engages first-year students contemplating engineering in realistic engineering experiences. This helps solidify their understanding of what engineering is, the kinds of activities engineers engage in, and the elements of engineering design. The most popular second-semester course includes a substantial robotics project which includes planning, budgeting, documentation, teamwork, and of course the technical aspects of designing, programming, constructing, and testing a robot. This course is now in its 25th year. Instructors have based course refinements on results in the science education literature and also assessed the impact of course modifications on the student and teaching assistant experiences. This presentation will give an overview of the project and share multiple examples of the varied ways students are made to be active in their learning process.

The discipline of physics suffers from low diversity at all educational levels. Our research seeks to understand the issues related to representation of women in physics related fields and to enhance diverse groups of students to advance and succeed in physics and related fields. In this talk, we will describe the role of students’ motivational characteristics in introductory level calculus-based physics courses. These studies aim to understand observed gender differences in students’ motivational factors that may arise, e.g., from societal biases against women’s ability to excel in physics. We will also discuss the link between prior knowledge and students’ learning outcomes across different student demographics and how motivational factors can explain this mechanism. We will describe how we use quantitative tools, such as Structural Equation Modeling, to evaluate complex models of student characteristics, attitudes as well as student learning outcomes. Finally, we will also describe how small and large-scale interventions can mitigate the representation issues, and can create inclusive and equitable learning environments.

Why it is critical to explicitly focus on making physics classes equitable and inclusive

Periodic review by a department of its programs can be a rewarding opportunity for reflection, evaluation, and improvement; assisting a department with its review as an external consultant is also rewarding. This presentation will review how to find these rewards with a specific focus on the advantages to departments of using external consultants and suggestions for consultants on how they can be most effective. The advantages of a departmental review lie in taking a systematic approach that includes gathering relevant data on a regular basis, assessing the data regularly, and regularly assessing and revising departmental initiatives designed to achieve desired improvements. Though the detailed planning and development of strategic initiatives are the responsibilities of the department and its institution, external consultants can help a department pay closer attention to trends in their data and outcomes, ask critical questions that may have been overlooked, and direct them to examples of alternative practices and models, in addition to providing useful findings and recommendations. This presentation draws heavily on chapters of the new EP3 guide: Effective Practices for Physics Programs which provides advice and suggestions for both physics departments and external consultants during the departmental review process.

A novel method is proposed for how LEGO race cars can help students increase their understanding of uncertainty and motivate them in physics labs. The intervention was developed for students in an introductory physics topic with a high early drop-out rate. This intervention was extended into the intro level physics topic the next year, for comparison and evaluation. A qualitative survey of the students was taken to gain insight into their perception of the incorporation of LEGO into physics labs. In this talk, I will discuss the results of the study and how variations in the delivery yielded better learning outcomes. We subsequently adapted the delivery of the LEGO labs for a large Engineering Mechanics cohort. For Engineering, the findings show that LEGO physics was instrumental in teaching students ideas of measurement and uncertainty, improving their lab reporting skills, and was a key factor in reducing the early attrition rate.

Race to improve student understanding of uncertainty: Using LEGO race cars in the physics lab

When assigning a computational activity, it's a common best practice for physics educators to provide students with a minimally working program (MWP) that the students modify, rather than asking them to code from scratch. On-line coding platforms such as GlowScript and Trinket make it easy to deploy MWPs and for students to share their completed work. I’ll discuss how we can supplement this best practice with pre-class video tutorials about our MWPs and outline a process for scaffolding student learning using MWPs. I’ll also describe some challenges one can encounter with MWPs (such as, “Do students really learn how the MWP works?” “Do skills and understanding really carry over from one activity to the next?”) and open the floor for discussion about how we might address those challenges.

The Opportunities and Challenges of Minimally Working Programs

Writing is an integral part of the process of science. In the undergraduate physics curriculum, the most common place that students engage with scientific writing is in lab classes, typically through lab notebooks, reports, and proposals. There has not been much research on why and how we include writing in physics lab classes, and instructors may incorporate writing for a variety of reasons. Through a broader study of multiweek projects in advanced lab classes, we have developed a framework for thinking about and understanding the role of writing in lab classes. This framework defines and describes the breadth of goals for incorporating writing in lab classes, and is a tool we can use to begin to understand why, and subsequently how, we teach scientific writing in physics.

Framework of goals for writing in physics lab classes

The 19th-century was a period of giant leaps in physics. Young demonstrated the wave nature of light. Dalton developed atomic theory. Maxwell unified electricity and magnetism. The list goes on and on. At the end of the century, Lord Kelvin famously declared, “There is nothing new to be discovered in physics now.” Each of these discoveries were performed by human beings, who were influenced by their educational background, family upbringing, religious beliefs, and more. For example, Young stated: “For the talents which God has not given me, I am not responsible, but those which I possess, I have hitherto cultivated and employed as diligently as my opportunities have allowed me to do.” How did this belief in God’s gifts of talent impact his scientific work? This talk will focus on the religious views of significant physicists of the 1800’s. Particularly, we will examine how the Christian faith of many 19th-century physicists influenced their scientific endeavors and shaped the field of physics as we know it.

The Influence of Christianity on 19th-Century Physicists

One of my favorite first day activities is to ask students to share rumors that they heard about the course, instructor, or Physics in general. After some general awkwardness and reassurance, students begin to open up about familiar fears such as heavy workloads, harsh grading, and very abstract concepts. But they may also attempt humor and playfulness, providing a unique opportunity to build community and paint the instructor’s role as a coordinator rather than an authoritarian voice in the classroom. Soliciting rumors can help the instructor explain course policies and expectations with an accessible tone that helps to break down barriers in the classroom. Some caution needs to be taken when using this activity because it opens the instructors up to criticism and makes them vulnerable (but is that so bad?). This activity was initially designed by Robert Beichner.

Low retention rates in physics Ph.D. programs are an unpleasant reality. There have been many efforts to study and report doctoral attrition and most studies have focused on students’ attributes and mentoring relationships. However, not much work has been focused on examining the interconnection between individual attributes and departmental practices. Last year, using survey data from 19 physics graduate programs, we identified 31 students that were not intending to complete their degree. About half of these students were enrolled in two institutions. In this talk, we use survey and interview data to describe factors related to why these students did not complete their doctoral programs. For example, students who dropped out often described feeling that they did not belong in the department and that they needed to figure things out on their own. We discuss how these results can inform policymakers’ decisions towards improving retention of doctoral students.
