Gender Differences in the High School and Affective Experiences of Introductory College Physics Students

The disparity in persistence between males and females studying physics has been a topic of concern to physics educators for decades. Overall, while female students perform as well as or better than male students,1 they continue to lag considerably in terms of persistence. The most significant drop in females studying physics occurs between high school and college.2 Since most female physicists report that they became attracted to physics and decided to study it further while in high school, according to the International Study of Women in Physics,3 it is problematic that high school is also the stage at which females begin to opt out at much higher rates than males. Although half of the students taking one year of physics in high school are female, females are less likely than males to take a second or Advanced Placement (AP) physics course.4 In addition, the percentage of females taking the first physics course in college usually falls between 30% and 40%.1 In other words, although you may see gender pa...

Career Outcome Expectations Related to Sustainability among Students Intending to Major in Civil Engineering

AbstractLearning more about the career outcome expectations of students interested in civil engineering can help identify gaps between their expectations and sustainability challenges. The authors used data from two national surveys to compare students interested in civil engineering and other engineering disciplines. Those interested in civil engineering are more likely to address such sustainability topics as environmental degradation, water supply, and climate change. However, civil engineering students are less likely to have outcome expectations related to disease and saving lives. Particularly, female students interested in civil engineering have similar expectations to males but also hope to address poverty and opportunities for women and minorities. The gaps in outcome expectations related to disease and saving lives are troubling for a profession that is so instrumental in providing, for example, clean water and safe shelter. Showing the connection between societal needs and civil engineering may...

The Importance of High School Physics Teachers for Female Students’ Physics Identity and Persistence

Given the historic and continued underrepresentation of women in physics, it is important to understand the role that high school physics might play in attracting female students to physics careers. Drawing on data from over 900 female undergraduates in physics, we examine when these women became interested in physics careers and different sources of recognition (important for physics identity development) that may have affected their choices at certain time points. The results provide optimism since many of these female students, even those not previously intending science careers, began to intend physics careers in high school and recognition from high school physics teachers had a significant effect on predicting these intentions.

High school experiences and climate change beliefs of first year college students in the United States

Abstract Climate change has not been well understood by high school students in the US and the topic is often connected to misconceptions, which is especially damaging since accurate understandings of the concepts are strongly predictive of intent to do something about it. We use data from a national (US) survey of first year college students to identify high school experiences which correlate with the belief that climate change is caused by human activities. In-class coverage of climate change is less predictive of belief than time spent on science homework or science-themed extracurricular activities. These correlations suggest that simply covering climate change in class may not necessarily lead to greater belief in the scientific consensus. While deeper understanding is a worthy goal, the results indicate that, when it comes to high school science education, social factors such as the process and culture of education are also important for belief in climate change. These finding aligns with previous research about college students, which suggest student activities are more strongly correlated with student viewpoints than professor beliefs. Given the potential for curricula to become politicized these finding suggests an alternative route to achieve climate change education goals.

Towards Meaningful Physics Recognition: What does this recognition actually look like?

In the February 2017 issue of The Physics Teacher, an article was presented that highlighted the importance of high school physics teachers in inspiring women in physics, particularly by recognizing them as being a “physics person.” Drawing on data from over 900 female undergraduates in physics, the article showed that the largest fraction became interested in physics careers during high school. In particular, being recognized by their physics teacher substantially increased the odds of their planning physics careers by the beginning of college. Since this article was published, questions have been directed toward us from physics teachers regarding the nature of recognition, e.g., how do we recognize a student meaningfully and what does recognition look like in the classroom? For example, one teacher wrote saying: I specifically wanted to tell you how much I appreciated this: …your closing note that not all recognition is meaningful, and that the key is high expectations for all and recognition of when [expectations are] met…I wrote in my margins on the page before, “What does this recognition actually look like?”In the February 2017 issue of The Physics Teacher, an article was presented that highlighted the importance of high school physics teachers in inspiring women in physics, particularly by recognizing them as being a “physics person.” Drawing on data from over 900 female undergraduates in physics, the article showed that the largest fraction became interested in physics careers during high school.

Episodic memories and the longitudinal impact of high school physics on female students’ physics identity

ABSTRACT Students enter physics classes with negative attitudes towards physics compared to the other sciences. Female students are more likely to opt out of a second higher-level physics course. Thus, the broad goal of this work is to better understand how to have the most lasting positive impact on female students’ attitudes and motivations towards learning physics after a single physics course in high school. Through longitudinal case studies of six female students using the frameworks of episodic memory and physics identity, we explore the most impactful features of students’ high school physics experiences. The data is drawn from three years of student interviews and one initial student survey. Our results indicate that the students could remember in detail and with longevity their experiences with physics causing high arousal and negative initial valence, such as teachers presenting physics knowledge in a counter-intuitive way. The students can remember the context but not the details of their experiences with physics causing low arousal and non-neutral valence, such as their teacher sharing a story about physics. Experiences that were eventually tied to positive valence had positive impacts on female students’ physics identity maintenance, such as problem solving activities where no one was left behind.

Understanding the development of interest and self-efficacy in active-learning undergraduate physics courses

ABSTRACT Modeling Instruction (MI), an active-learning introductory physics curriculum, has been shown to improve student academic success. Peer-to-peer interactions play a salient role in the MI classroom. Their impact on student interest and self-efficacy – preeminent constructs of various career theories – has not been thoroughly explored. Our examination of three undergraduate MI courses (N = 221) revealed a decrease in students’ physics self-efficacy, physics interest, and general science interest. We found a positive link from physics interest to self-efficacy, and a negative relationship between science interest and self-efficacy. We tested structural equation models confirming that student interactions make positive contributions to self-efficacy. This study frames students’ classroom interactions within broader career theory frameworks and suggests nuanced considerations regarding interest and self-efficacy constructs in the context of undergraduate active-learning science courses.

Interest in STEM is contagious for students in biology, chemistry, and physics classes

Students who perceive a high level of interest among classmates in science classes are more likely to intend pursuing STEM. We report on a study of the effect of peers’ interest in high school biology, chemistry, and physics classes on students’ STEM (science, technology, engineering, and mathematics)–related career intentions and course achievement. We define an interest quorum as a science class where students perceive a high level of interest for the subject matter from their classmates. We hypothesized that students who experience such an interest quorum are more likely to choose STEM careers. Using data from a national survey study of students‘ experiences in high school science, we compared the effect of five levels of peer interest reported in biology, chemistry, and physics courses on students‘ STEM career intentions. The results support our hypothesis, showing a strong, positive effect of an interest quorum even after controlling for differences between students that pose competing hypotheses such as previous STEM career interest, academic achievement, family support for mathematics and science, and gender. Smaller positive effects of interest quorums were observed for course performance in some cases, with no detrimental effects observed across the study. Last, significant effects persisted even after controlling for differences in teaching quality. This work emphasizes the likely importance of interest quorums for creating classroom environments that increase students’ intentions toward STEM careers while enhancing or maintaining course performance.
