Yet prior work suggests that access to quantum workforce education is unequally distributed, disproportionately benefiting students at private research-focused institutions whose student bodies are unrepresentative of U.S. higher education as a whole. We use regression analysis to analyze the distribution of QIS coursework across 456 institutions of higher learning as of Fall 2022, identifying statistically significant disparities across institutions in particular along the axes of institution classification, funding, and geographic distribution suggesting today’s QIS education programs are largely failing to reach low-income and rural students. We also conduct a brief analysis of the distribution of emerging dedicated QIS degree programs, discovering much the same trends. We conclude with a discussion of implications for educators, policymakers, and education researchers including specific policy recommendations to direct investments in QIS education to schools serving low-income and rural students, leverage existing grassroots diversity and inclusion initiatives that have arisen within the quantum community, and update and modernize procedures for collecting QIS educational data to better track these trends.","PeriodicalId":54296,"journal":{"name":"Physical Review Physics Education Research","volume":"28 1","pages":""},"PeriodicalIF":3.1,"publicationDate":"2024-05-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140839590","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"教育学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the evaluation of students’ decisions in these problems can pose a problem: e.g., students making a correct decision for the wrong reasons. Three previous studies, that share the same context and data comparison problem but where participants had increasing conceptual knowledge of measurement uncertainties, are revisited. The comparison shows a troublesome result: increasing conceptual knowledge does not lead to better decision making in the data comparison problem. In this research, we have looked into this apparent discrepancy by comparing and reanalyzing the data from these three studies. We have analyzed students’ justifications by coding them based on the compared quantity and the deciding criterion, giving a highly detailed insight into what they do when comparing the datasets. The results show clear differences in the quality of the justifications across the studies and by combining the results with the decisions, we could successfully identify four cases of correct and incorrect decisions for right or wrong reasons. This analysis showed a high prevalence of correct decisions for wrong reasons in two of the studies, resolving the discrepancy in the initial comparison of these studies. The implication of our analysis is that simply asking students to make a decision in data comparison problems is not a suitable probe to gauge their ability to compare datasets or their conceptual understanding of measurement uncertainties and a probe like this should always be complemented by an analysis of the justification.","PeriodicalId":54296,"journal":{"name":"Physical Review Physics Education Research","volume":"1 1","pages":""},"PeriodicalIF":3.1,"publicationDate":"2024-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140806637","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"教育学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To better integrate computational thinking in introductory physics, we need to understand what physicists find important about computational thinking in introductory physics. We present a qualitative analysis of 26 interviews asking academic (<math display=\"inline\" xmlns=\"http://www.w3.org/1998/Math/MathML\"><mrow><mi>N</mi><mi>_</mi><mi>a</mi><mrow><mo>=</mo><mn>18</mn></mrow></mrow></math>) and industrial (<math display=\"inline\" xmlns=\"http://www.w3.org/1998/Math/MathML\"><mrow><mi>N</mi><mi>_</mi><mi>i</mi><mrow><mo>=</mo><mn>8</mn></mrow></mrow></math>) physicists about the teaching and learning of computational thinking in introductory physics courses. These interviews are part of a long-term project toward developing an assessment protocol for computational thinking in introductory physics. We find that academic and industrial physicists value students’ ability to read code and that <span>python</span> (or <span>vpython</span>) and spreadsheets were the preferred computational language or environment used. Additionally, the interviewees mentioned that identifying the core physics concepts within a program, explaining code to others, and good program hygiene (i.e., commenting and using meaningful variable names) are important skills for introductory students to acquire. We also find that while a handful of interviewees note that the experience and skills gained from computation are quite useful for student’s future careers, they also describe multiple limiting factors of teaching computation in introductory physics, such as curricular overhaul, not having “space” for computation’, and student rejection. The interviews show that while adding computational thinking to physics students’ repertoire is important, the importance really comes from using computational thinking to learn and understand physics better. This informs us that the assessment we develop should only include the basics of computational thinking needed to assess introductory physics knowledge.","PeriodicalId":54296,"journal":{"name":"Physical Review Physics Education Research","volume":"25 1","pages":""},"PeriodicalIF":3.1,"publicationDate":"2024-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140804184","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"教育学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A sample of 1197 high school students participated in the study. The collected data were analyzed using structural equation modeling. The analysis results indicated that the model fitted the data well, further motivating intervention studies to test the causal relations proposed in the model. The results showed that recognition and interest directly predicted physics identity and mediated the relation of physics self-efficacy to it. Metacognition and epistemic cognition predicted physics identity through physics self-efficacy. The study also observed significant direct and indirect relations among metacognition, epistemic cognition, self-efficacy, recognition, and interest. Furthermore, gender differences were found in the current study. While no gender difference was observed in metacognition and epistemic cognition in physics, male students scored higher than female students in physics identity, self-efficacy, recognition, and interest. However, the mediation analysis further indicated that gender differences in physics self-efficacy might explain gender differences in physics identity, recognition, and interest. The results of this study could motivate future interventions testing the effect of metacognitive and epistemic activities on both physics self-efficacy and identity, and also, the interventions testing whether practices that reduce the gender gap in physics self-efficacy will help eliminate the gender gap in physics identity, recognition, and interest.","PeriodicalId":54296,"journal":{"name":"Physical Review Physics Education Research","volume":"25 1","pages":""},"PeriodicalIF":3.1,"publicationDate":"2024-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140804050","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"教育学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, research has also found a gender bias in peer recognition in which student nominations of strong peers in their physics course disproportionately favor men over women. In this study, we draw on methods from social network analysis and find a consistent gender bias in which men disproportionately undernominate women as strong in their physics course in two offerings of both a lecture course (for science and engineering, but not physics, majors) and a distinct lab course (for science, engineering, and physics majors). We also find in one offering of the lecture course that women disproportionately undernominate men, contrary to what previous research would predict. We expand on prior work by also probing two data sources related to who and what gets recognized in peer recognition: students’ interactions with their peers (who gets recognized) and students’ written explanations of their nominations of strong peers (what gets recognized). Results suggest that the nature of the observed gender bias in peer recognition varies between the instructional contexts of lecture and lab. In the lecture course, the gender bias is related to who gets recognized: both men and women disproportionately overnominate their interaction ties to students of their same gender as strong in the course. In the lab course, the gender bias is also related to what gets recognized: men nominate men more than women because of skills related to interactions, such as being helpful. These findings illuminate the different ways in which students form perceptions of their peers and add nuance to our understanding of the nature of gender bias in peer recognition.","PeriodicalId":54296,"journal":{"name":"Physical Review Physics Education Research","volume":"81 1","pages":""},"PeriodicalIF":3.1,"publicationDate":"2024-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140592614","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"教育学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We found that though indicators of substance-based reasoning about current are common in student responses, this reasoning is not predictive of other difficulties reported in the literature, such as “current is consumed” or “the battery is a constant source of current.” We also found that students use substance-based reasoning in resourceful ways, suggesting that substance-based reasoning may in fact be a productive starting place for instruction on circuits.","PeriodicalId":54296,"journal":{"name":"Physical Review Physics Education Research","volume":"58 27 1","pages":""},"PeriodicalIF":3.1,"publicationDate":"2024-04-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140593170","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"教育学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We use personas methodology and self-determination theory to articulate their public engagement motivation, challenges, and needs. We present our set of three personas: the physicist who engages in informal physics for self-reflection, the physicist who wants to spark interest and understanding in physics, and the physicist who wants to provide diverse role models to younger students and inspire them to pursue a science, technology, engineering, and mathematics career. Needs covered a range of resources including science communication training, community building among informal physics practitioners, and mechanisms to recognize, elevate, and value informal physics. By bringing user-centered design methodology to a new topical area of physics education research, we expand our understanding of motivations and needs of practitioners in physics public engagement. Therefore, departments, organizations, and institutions could draw upon the personas developed to consider the ways to better support physicists in their respective environments.","PeriodicalId":54296,"journal":{"name":"Physical Review Physics Education Research","volume":"69 1","pages":""},"PeriodicalIF":3.1,"publicationDate":"2024-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140592617","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"教育学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Traditionally, test anxiety scales have been developed for mathematics, but few studies have focused on physics. In this study, we validated two test anxiety scales for undergraduate physics courses: the Test Anxiety Inventory for Physics (TAIP) and the Abbreviated Test Anxiety Inventory for Physics scale (ATAIP), which were adapted from existing instruments. A convenience sample of 361 engineering students enrolled in a first-semester introductory physics course participated in the study. Confirmatory factor analysis and Rasch analysis were used to establish the construct validity of both scales. Convergent validity for the TAIP scale was established by examining its correlation with a scale adapted from the math anxiety scale. Criterion-related validity for both TAIP and ATAIP was established by analyzing the relationship between students’ Rasch scores on the two scales and their performance on two conceptual tests. Finally, measurement invariance of TAIP and ATAIP scales was established using both multigroup and differential item functioning analyses to reliably investigate gender differences in the corresponding Rasch measures. The study confirms a robust four-factor structure of the TAIP. The four subscales, Worry, Emotionality, Interference, and Lack of Confidence, demonstrate good reliability (McDonald’s <math display=\"inline\" xmlns=\"http://www.w3.org/1998/Math/MathML\"><mrow><mi>ω</mi><mo>=</mo><mn>0.78</mn><mo>,</mo><mn>0.86</mn><mo>,</mo><mn>0.87</mn><mo>,</mo><mn>8</mn><mn>7</mn></mrow></math>, respectively). Rash analysis also confirms that, for each subscale, the rating scale functioning was consistent with the item difficulty and person measures. The TAIP also demonstrates adequate convergent and criterion-related validity, as well as measurement invariance with respect to gender. The ATAIP also demonstrates good reliability (McDonald’s <math display=\"inline\" xmlns=\"http://www.w3.org/1998/Math/MathML\"><mrow><mi>ω</mi><mo>=</mo><mn>0.84</mn></mrow></math>), a well-functioning rating scale, and sufficient criterion-related validity. Additionally, it exhibits measurement invariance with respect to gender. Overall, the study supports that both the TAIP and ATAIP scales are reliable instruments for measuring students’ test anxiety in an undergraduate physics course. Implications for physics instruction at the university introductory level are briefly discussed.","PeriodicalId":54296,"journal":{"name":"Physical Review Physics Education Research","volume":"43 1","pages":""},"PeriodicalIF":3.1,"publicationDate":"2024-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140592846","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"教育学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Former works have often recorded the notion of gendered mean FCI scores favoring male students notably in the North American (NA) based studies. Nevertheless, these performance gaps remain inconclusive and unexplored outside the NA context. This paper aims to fill this gap by meta-analyzing the mean FCI scores between gender based on the existing physics education research literature internationally. We analyzed the magnitude and direction on the mean FCI scores between gender based on primary international studies published over the last two decades. We also explored the moderating impact of international study characteristics on the meta-analytic findings by performing a subgroup analysis to study the different study regions stratified by two subgroups (NA vs non-NA authors). Thirty-eight studies reporting the mean FCI scores by gender were included in the present meta-analysis. We employed Hedges’ <math display=\"inline\" xmlns=\"http://www.w3.org/1998/Math/MathML\"><mi>g</mi></math> statistic to estimate to what degree the mean FCI scores may be different between male and female students on each study. Under a random effects model, we meta-analyzed the findings and conducted a subgroup analysis to answer the research questions. In summary, our meta-analysis indicated a significantly positive and moderate amount of gendered mean FCI scores in favor of male students both in NA- and non-NA based regions, and the performance gaps were wider in the NA-based studies. Suggestions are discussed while interpreting the mean FCI scores between gender for teaching, learning, and forthcoming studies.","PeriodicalId":54296,"journal":{"name":"Physical Review Physics Education Research","volume":"47 1","pages":""},"PeriodicalIF":3.1,"publicationDate":"2024-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140592940","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"教育学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Factors leading to variation in post-test scores on the Force and Motion Conceptual Evaluation (FMCE) across different instructors, semesters, and course models in a sample collected in introductory calculus-based mechanics at a large, eastern land-grant university were examined. The sample was collected over nine years and contains a total of <math display=\"inline\" xmlns=\"http://www.w3.org/1998/Math/MathML\"><mi>N</mi><mo>=</mo><mn>4409</mn></math> matched pretest and post-test records.

Neither the normalized gain nor Cohen’s <math display=\"inline\" xmlns=\"http://www.w3.org/1998/Math/MathML\"><mi>d</mi></math> removed the semester-to-semester variation observed in post-test scores. The local average curve plotting post-test scores against pretest scores, which we call a conceptual growth curve, allowed for the characterization of outcomes for students with different pretest scores. Regression models were used to produce an approximation to this curve. By using either the full curve or a mathematical approximation developed through linear regression, the post-test score that would be observed if a class enrolled students with a given level of prior preparation measured by pretest scores can be predicted. This predicted post-test score can then be used to calculate the predicted normalized gain if desired. These methods rely on using the natural variation of incoming student preparation at one institution to predict how a class would perform if it enrolled students with different prior preparation. The study presents an example of converting the outcomes at an institution with a weakly prepared student population to the outcomes which would have been observed if the course enrolled a more prepared student population; converting the outcomes for a different student population dramatically changed the interpretation of how the class studied was functioning.","PeriodicalId":54296,"journal":{"name":"Physical Review Physics Education Research","volume":"14 1","pages":""},"PeriodicalIF":3.1,"publicationDate":"2024-04-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140592607","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"教育学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
