    Objective To determine if student outcomes, usage, perceptions, and engagement differ between introductory nutrition courses that used an open educational resource (OER) textbook compared with a traditional textbook. Design Cross-sectional. Setting College introductory nutrition course. Participants Students enrolled in introductory nutrition courses that used a traditional textbook or an OER textbook. Intervention Implementation of an OER textbook in all introductory nutrition courses during 1 semester. Main Outcome Measure(s) Usage, perceptions, and engagement with the textbook were evaluated by an online survey. Student outcome data (eg, grades) were collected from the learning management system at the end of the semester. Analysis Differences in student outcomes, usage, perceptions, and engagement were determined by t tests. Open-ended responses on textbook likes and dislikes were evaluated by thematic analysis. Results The number of students who completed the introductory nutrition course with a traditional textbook (n = 346) was higher than those who completed the course with an OER textbook (n = 311). There was no difference in student outcomes between textbooks. P values for student usage ranged from <.001 to .001, <.001 for engagement, and <.001 to .001 for perception with the OER textbook, with significantly better P values for outcomes than those with the traditional textbook. The $0 cost and place-based nature were noted as positive attributes of the OER textbook, whereas students appreciated the format and visual appeal of the traditional textbook. Conclusions and Implications Academic performance in introductory nutrition was not affected by an OER textbook. An OER textbook for introductory nutrition may be an appropriate solution for institutions seeking to reduce student costs

    Implicit Theories and Self-efficacy in an Introductory Programming Course

    Contribution: This study examined student effort and performance in an introductory programming course with respect to student-held implicit theories and self-efficacy. Background: Implicit theories and self-efficacy shed a light into understanding academic success, which must be considered when developing effective learning strategies for programming. Research Questions: Are implicit theories of intelligence and programming, and programming-efficacy related to each other and student success in programming? Is it possible to predict student course performance using a subset of these constructs? Methodology: Two consecutive surveys (N=100 and N=81) were administered to non-CS engineering students in I\c{s}{\i}k University. Findings: Implicit theories and self-beliefs are interrelated and correlated with effort, performance, and previous failures in the course and students explain failure in programming course with "programming-aptitude is fixed" theory, and also that programming is a difficult task for themselves.Comment: Programming Education. 8 page

    Highly prevalent but not always persistent: undergraduate and graduate student's misconceptions about psychology.

    Although past research has documented the prevalence of misconceptions in introductory psychology classes, few studies have assessed how readily upper-level undergraduate and graduate students endorse erroneous beliefs about the discipline. In Study 1, we administered a 30-item misconception test to an international sample of 670 undergraduate, Master’s and doctoral students. Analyses indicated that participants identified and rejected the majority of misconceptions, with doctoral students performing better than their Master’s or undergraduate peers. In Study 2, we administered a revised version of our questionnaire to a novel sample of 557 students while controlling for number of years spent at university, psychology courses completed and need for cognition. Once again, we found that graduate students rejected more, affirmed less and reported lower levels of uncertainty than their undergraduate counterparts. Educational implications and future research directions are discussed

    Surveying Turkish high school and university student attitudes and approaches to physics problem solving

    Student attitudes and approaches to problem solving can impact how well they learn physics. Prior research in the US using a validated Attitude and Approaches to Problem Solving (AAPS) survey suggests that there are major differences between students in introductory physics and astronomy courses and physics experts in terms of their attitudes and approaches to physics problem solving. Here we discuss the validation, administration and analysis of data for the Turkish version of the AAPS survey for high school and university students in Turkey. After the validation and administration of the Turkish version of the survey, the analysis of the data was conducted by grouping the data by grade level, school type, and gender. While there are no statistically significant differences between the averages of various groups on the survey, overall, the university students in Turkey were more expert-like than vocational high school students. On an item by item basis, there are statistically differences between the averages of the groups on many items. For example, on average, the university students demonstrated less expert-like attitudes about the role of equations and formulas in problem solving, in solving difficult problems, and in knowing when the solution is not correct, whereas they displayed more expert-like attitudes and approaches on items related to meta-cognition in physics problem solving. A principal component analysis on the data yields item clusters into which the student responses on various survey items can be grouped. A comparison of the responses of the Turkish and American university students enrolled in algebra-based introductory physics courses shows that on more than half of the items, the responses of these two groups were statistically significantly different with the US students on average responding to the items in more expert-like manner.Comment: 16 pages, Keywords: Physics Education Research, Attitudes and approaches to problem solving, Turkish students, American students, factor analysis, principal component analysi

    How physics instruction impacts students' beliefs about learning physics: A meta-analysis of 24 studies

    Get PDF
    In this meta-analysis, we synthesize the results of 24 studies using the Colorado Learning Attitudes about Science Survey (CLASS) and the Maryland Physics Expectations Survey (MPEX) to answer several questions: (1) How does physics instruction impact students' beliefs? (2) When do physics majors develop expert-like beliefs? and (3) How do students' beliefs impact their learning of physics? We report that in typical physics classes, students' beliefs deteriorate or at best stay the same. There are a few types of interventions, including an explicit focus on model-building and/or developing expert- like beliefs that lead to significant improvements in beliefs. Further, small courses and those for elementary education and non-science majors also result in improved beliefs. However, because the available data oversamples certain types of classes, it is unclear whether these improvements are actually due to the interventions, or due to the small class size, or student population typical of the kinds of classes in which these interventions are most often used. Physics majors tend to enter their undergraduate education with more expert-like beliefs than non-majors and these beliefs remain relatively stable throughout their undergraduate careers. Thus, typical physics courses appear to be selecting students who already have strong beliefs, rather than supporting students in developing strong beliefs. There is a small correlation between students' incoming beliefs about physics and their gains on conceptual mechanics surveys. This suggests that students with more expert-like incoming beliefs may learn more in their physics courses, but this finding should be further explored and replicated. Some unanswered questions remain. To answer these questions, we advocate several specific types of future studies.Comment: 30 pages. Accepted to Phys Rev ST-PE

    The motivation to express prejudice

    Get PDF
    Contemporary prejudice research focuses primarily on people who are motivated to respond without prejudice and the ways in which unintentional bias can cause these people to act inconsistent with this motivation. However, some real-world phenomena (e.g., hate speech, hate crimes) and experimental findings (e.g., Plant & Devine, 2001; 2009) suggest that some expressions of prejudice are intentional. These phenomena and findings are difficult to explain solely from the motivations to respond without prejudice. We argue that some people are motivated to express prejudice, and we develop the motivation to express prejudice (MP) scale to measure this motivation. In seven studies involving more than 6,000 participants, we demonstrate that, across scale versions targeted at Black people and gay men, the MP scale has good reliability and convergent, discriminant, and predictive validity. In normative climates that prohibit prejudice, the internal and external motivations to express prejudice are functionally non-independent, but they become more independent when normative climates permit more prejudice toward a target group. People high in the motivation to express prejudice are relatively likely to resist pressure to support programs promoting intergroup contact and vote for political candidates who support oppressive policies. The motivation to express prejudice predicted these outcomes even when controlling for attitudes and the motivations to respond without prejudice. This work encourages contemporary prejudice researchers to broaden the range of samples, target groups, and phenomena that they study, and more generally to consider the intentional aspects of negative intergroup behavior

    OBJECTIVES: We assessed the correlation between college students' perceived stress (PS) and healthy lifestyle factors (HLFs) in this cross-sectional study. METHODS: Data were collected from 1396 undergraduates enrolled in an introductory nutrition course. We measured PS and 5 HLFs (physically active, healthy diet, non-smoker, non-binge drinker, healthy BMI). RESULTS: The mean PS score was 15.0 ± 0.2 (maximum, 40) and the mean number of HLFs reported was 2.9 ± 0.03. Females were more likely to report 4-5 HLFs than males (31% vs 20%). We found a statistically significant inverse correlation between PS and HLFs for women (p < .01). CONCLUSIONS: Health promotion interventions that support healthy food choices, physical activity and low-risk substance use may reduce perceived stress in the college population.Published versio
