The perceptions that physics mentors have about disability in physics influences how they interact with their mentees, and negative biases against disability can influence students to feel discouraged within the physics community. We administered the Disability and Physics Career Survey (DPCS) through physics-specific listservs and at physics-specific conferences to measure practicing physicists' knowledge about disability and their beliefs about the viability of physics careers for individuals with a variety of disability diagnoses. This study uses Cochran's Q and McNemar's R to compare how practicing physicists' perceptions of the viability for the careers of teacher and professor depend on the impairment that an individual is diagnosed with. We find that practicing physicists view these careers as non-viable for those with cognitive impairments and hold other unconscious biases that we outline and interrogate. 

Despite the positive gains towards student learning outcomes and engagement, active learning has been shown to potentially increase student anxiety due to a fear of negative evaluation. A pedagogical strategy proposed to mediate this issue is known as error framing; it asks instructors to encourage a perception of errors as being a natural part of the learning process. Previous work on this project investigated how graduate teaching assistants (GTAs) operationalized error framing during their training in a mixed-reality simulator but did not investigate their usage of it in their classrooms. This analysis characterizes the error framing statements made by GTAs during a set of classroom observations. We find that GTAs who employ error framing effectively avoid statements that might decrease student comfort and instead tend towards implicit, indirect strategies. 

Abstract BackgroundIn college science laboratory and discussion sections, student-centered active learning strategies have been implemented to improve student learning outcomes and experiences. Research has shown that active learning activities can increase student anxiety if students fear that they could be negatively evaluated by their peers. Error framing (i.e., to frame errors as natural and beneficial to learning) is proposed in the literature as a pedagogical tool to reduce student anxiety. However, little research empirically explores how an instructor can operationalize error framing and how error framing is perceived by undergraduate students. To bridge the gap in the literature, we conducted a two-stage study that involved science graduate teaching assistants (GTAs) and undergraduate students. In stage one, we introduced cold calling (i.e., calling on non-volunteering students) and error framing to 12 chemistry and 11 physics GTAs. Cold calling can increase student participation but may increase student anxiety. Error framing has the potential to mitigate student anxiety when paired with cold calling. GTAs were then tasked to rehearse cold calling paired with error framing in a mixed-reality classroom simulator. We identified GTA statements that aligned with the definition of error framing. In stage two, we selected a few example GTA error framing statements and interviewed 13 undergraduate students about their perception of those statements. ResultsIn the simulator, all the GTAs rehearsed cold calling multiple times while only a few GTAs made error framing statements. A thematic analysis of GTAs’ error framing statements identified ways of error indication (i.e., explicit and implicit) and framing (i.e., natural, beneficial, and positive acknowledgement). Undergraduate student interviews revealed specific framing and tone that are perceived as increasing or decreasing student comfort in participating in classroom discourse. Both undergraduate students and some GTAs expressed negative opinions toward responses that explicitly indicate student mistakes. Undergraduate students’ perspectives also suggest that error framing should be implemented differently depending on whether errors have already occurred. ConclusionError framing is challenging for science GTAs to implement. GTAs’ operationalizations of error framing in the simulator and undergraduate students’ perceptions contribute to defining and operationalizing error framing for instructional practice. To increase undergraduate student comfort in science classroom discourse, GTAs can use implicit error indication. In response to students’ incorrect answers, GTAs can positively frame students’ specific ideas rather than discussing broadly how errors are natural or beneficial. 

We investigated student perceptions of cold calling on their feelings of anxiousness and how graduate teaching assistants (GTAs) alleviated these feelings when students shared their ideas publicly in the context of tutorial and laboratory sessions. Physics and chemistry GTAs who led active-learning tutorials and labs practiced cold calling paired with error framing with avatar-students in a mixed-reality simulator at the beginning of the semester. Then, we observed the GTAs teaching real students in their actual classroom. We recruited eleven students from sections led by GTAs who were observed to use cold calling in their classroom to participate in semi-structured interviews. Several students reported that cold calling increased their feelings of anxiousness. However, students also reported that GTAs used strategies paired with cold calling that reduced their feelings of anxiousness, such as acknowledging student responses as valuable and remembering student names. We discuss implications for professional development on active learning strategies.
