Influencing students’ relationships with physics through culturally relevant tools

This study investigates how an urban, high school physics class responded to the inclusion of a classroom set of iPads and associated applications, such as screencasting. The participatory roles of students and the expressions of their relationships to physics were examined. Findings suggest that iPad technology altered classroom norms and student relationships to include increased student agency and use of evidence. Findings also suggest that the iPad provided a connection between physics, social status, and play. Videos, observations, interviews, and survey responses were analyzed to provide insight into the nature of these changes.

Systemic inequities in introductory physics courses: the impacts of learning assistants

Creating equitable performance outcomes among students is a focus of many instructors and researchers. One focus of this effort is examining disparities in physics student performance across genders, which is a well-established problem. Another less common focus is disparities across racial and ethnic groups, which may have received less attention due to low representation rates making it difficult to identify gaps in their performance. In this investigation we examined associations between Learning Assistant (LA) supported courses and improved equity in student performance. We built Hierarchical Linear Models of student performance to investigate how performance differed by gender and by race/ethnicity and how LAs may have moderated those differences. Data for the analysis came from pre-post concept inventories in introductory mechanics courses collected through the Learning About STEM Student Outcomes (LASSO) platform. Our models show that gaps in performance across genders and races/ethnicities were similar in size and increased from pre to post instruction. LA-support is meaningfully and reliably associated with improvement in overall student performance but not with shifts in within-course performance gaps.

In-class vs. Online Administration of Concept Inventories and Attitudinal Assessments

This study investigates differences in student responses to in-class and online administrations of the Force Concept Inventory (FCI), Conceptual Survey of Electricity and Magnetism (CSEM), and the Colorado Learning Attitudes about Science Survey (CLASS). Close to 700 physics students from 12 sections of three different courses were instructed to complete the concept inventory relevant to their course, either the FCI or CSEM, and the CLASS. Each student was randomly assigned to take one of the surveys in class and the other survey online using the LA Supported Student Outcomes (LASSO) system hosted by the Learning Assistant Alliance (LAA). We examine how testing environments and instructor practices affect participation rates and identify best practices for future use.

From Fear to Self-Expression: The Contextual Nature of Physics Students’ Motivations

This study utilizes a sociocultural interpretation of Self-Determination Theory to better understand the role that learning contexts play in generating student motivation, engagement, and identity. By drawing on previous motivation research we develop a model that describes how student senses of belonging in social settings can transform their goals and experiences. We use the extremes of fear and integrity to model student motivations to engage in activities. Student senses of connection and belonging (or not) in social settings drives whether they feel integrated with or alienated from their environments. Our model is based on three studies and suggests that a sense of belonging emerges through the alignment of goals and practices of the individual and an activity. This model is applied to two examples to illustrate how social connection or isolation can be exhibited in a physics classroom setting. We conclude by discussing the role of the teacher in designing classroom environments that support students engaging.

Changing roles and identities in a teacher-driven professional development community

In a climate where teachers feel deprofessionalized at the hands of regulations, testing, and politics, it is vital that teachers become empowered both in their own teaching and as agents of change. This physics education research study investigates the Streamline to Mastery professional development program, in which the teachers design professional development opportunities for themselves and for fellow teachers. The research reported here describes the process of teacher professional growth through changes in roles and identities. Videos, emails, and interviews were analyzed to glean insight into practice and participation shifts as these physical science teachers formed a community and engaged in their own classroom research. Implications for the role of PER in teacher professional development and teacher preparation will be discussed.

Participation rates of in-class vs. online administration of low-stakes research-based assessments

This study investigates differences in student participation rates between in-class and online administrations of research-based assessments. A sample of 1,310 students from 25 sections of 3 different introductory physics courses over two semesters were instructed to complete the CLASS attitudinal survey and the concept inventory relevant to their course, either the FCI or the CSEM. Each student was randomly assigned to take one of the surveys in class and the other survey online at home using the Learning About STEM Student Outcomes (LASSO) platform. Results indicate large variations in participation rates across both test conditions (online and in class). A hierarchical generalized linear model (HGLM) of the student data utilizing logistic regression indicates that student grades in the course and faculty assessment administration practices were both significant predictors of student participation. When the recommended online assessments administration practices were implemented, participation rates were similar across test conditions. Implications for student and course assessment methodologies will be discussed.

Teaching to Learn: iPads as Tools for Transforming Physics Student Roles

Students who serve as Learning Assistants (LAs) and have the opportunity to teach the content they are learning, while also studying effective teaching pedagogy, have demonstrated achievement gains in advanced content courses and positive shifts in attitudes about learning science [V. Otero, S. Pollock & N. Finkelstein, Amer J Physics 78, 11 (2010)]. Although the LA experience is also valuable for high school students, the tight schedule and credit requirements of advanced high school students limit opportunities for implementing traditional LA programs at the high school level. In order to provide high school physics students with an LA-like experience, iPads were used as tools for students to synthesize screencast video tutorials for students to access, review and evaluate. The iPads were utilized in a one-to-one tablet-to-student environment throughout the course of an entire school year. This research investigates the impact of a one-to-one iPad environment and the use of iPads to create teaching-to-learn (TtL) experiences on student agency and attitudes toward learning science.
