Brain Type or Sex Differences? A structural equation model of the relation between brain type,sex, and motivation to learn science

Sex is considered to be one of the most significant factors influencing attitudes towards science. However, the so-called brain type approach from cognitive science suggests that the difference in motivation to learn science does not primarily differentiate the girls from the boys, but rather the so-called systemisers from the empathizers. The present study investigates this hypothesis by using structural equation modelling on a sex-stratified sample of 500 male and female students of secondary II level. The results show, that the motivation to learn science is directly influenced by the systemizing quotient SQ, but not by sex. The impact of sex on the motivation to learn science, measured by five key concepts, only works indirectly, namely through the influence of sex on the SQ. The empathizing quotient (EQ) has no impact on the motivation to learn science. The SQ explains between 13 and 23 percent of the variation of the five key constructs. In female students, the impact of the SQ is very similar for all key concepts. In male students, it is highest for self-efficacy and lowest for assessment anxiety. The motivation to learn science is significantly larger for male students in all involved SMQ key concepts, but the difference is small. The interpretation of these findings and conclusions for science teaching and further research are discussed.     

Enclothed cognition: putting lab coats to the test

ABSTRACT

Although there has been some success with programmes that aim to increase STEM involvement by women and underserved minorities, science educators continue to seek ways to promote students’ interest in STEM. This study builds on social cognitive career theory (SCCT) and the theory of enclothed cognition to assess the impact of wearing lab coats on 5th-grade students. Students were assigned to a treatment group (that wore lab coats, n = 106) or a control group (that did not wear lab coats, n = 110) for 10 science classes taught by their classroom science teacher. Students were assessed pre and post to the intervention with a survey designed to measure science interest, recognition from others as a science person, science self-efficacy, and STEM career goals. Results showed students’ interest in science was not significantly changed due to wearing the lab coat, but the lab coats did have significant effects on students’ perceived recognition by others as being a science learner. Furthermore, those treatment students with low self-efficacy (compared to those with high self-efficacy) and those with who did not report having access to a parent with a STEM career had significant increases in perceptions of self-efficacy in science.     

Elementary Pre-Service Teachers' Response-Shift Bias: Self-efficacy and attitudes toward science

Response-shift bias occurs when participants' initial constructs, such as self-efficacy in teaching science, are incomplete because they do not fully conceptualize something they have yet to experience. This study examines whether elementary pre-service teachers can consistently evaluate constructs such as self-efficacy and attitudes toward science throughout an elementary methods course. After the administration of traditional pre-tests, retrospective pre-tests, and post-tests, this study examined whether a response-shift bias consistently occurred in scales indicating science teaching self-efficacy (as measured by the Science Teaching Efficacy Beliefs Instrument-B), attitudes toward science (modified Attitudes Toward Science Inventory), and relevancy of science (Changes in Attitudes about the Relevancy of Science). Results indicate that a significant response-shift bias occurred in the scales relating to self-efficacy, confidence, and attitudes toward science; while no response-shift bias occurred in scales relating to outcome expectancy, value, and relevancy of science. Our data provide evidence that response-shifts naturally discriminate among different constructs and that participants successfully and consistently reported certain constructs over time which may be of interest for program evaluators and self-efficacy researchers. This research could have implications for program evaluators and researchers who need to measure program impacts on pre-service teachers with limited science-teaching experiences.     

Philosophical Approaches of Religious Jewish Science Teachers Toward the Teaching of ‘Controversial’ Topics in Science

This research examines the problems that religious Jewish science teachers in Israeli high schools have in coping with science subjects (such as geological time) which conflict with their religious beliefs. We do this by characterizing the philosophical approaches within Judaism that such teachers have adopted for dealing with such controversy. Thus, we surveyed 56 religious teachers using a Likert‐type questionnaire developed for this research, as well as interviewed 11 teachers to more deeply probe their approaches. In addition, we surveyed 15 religious scientists, so that we could both contrast their views with our teacher samples as well as to better understand their coping strategies when confronted by scientific topics that challenge their beliefs. Results indicated that no single philosophical approach earned overwhelming support from the teachers or scientists. Instead, most of the subjects relate separately to each source of possible conflict in accordance with the philosophical approach that appears to be the most fruitful for resolving such conflicts. Moreover, both the scientists and the teachers felt less conflicted toward the specific subject of geological time, in comparison to issues connected to creation of the earth and (especially) evolution. The teachers did differ from the scientists in their preference toward philosophical approaches which help them better integrate the domains of science and religion. Based on our findings, we are able to suggest a set of strategies to help teachers overcome their difficulties in teaching ‘controversial’ science topics to a religiously oriented student population.     

Valuing Science: A Turkish–American comparison

A problem that is still unexplored in the field of socioscientific issues (SSI) and that was explored in this study is how different students decide upon a SSI they are discussing, how their justifications change during the instruction and how they use (or not) the evidence from the learning environment to support their justifications. For the purposes of this study, two classes (12–13-year-old students) with diverse characteristics were selected from two different schools in the UK. Class A students, considered high achievers come from a white-British background. Class B students considered average achievers come from an Asian British background. The students engaged in discussions regarding a SSI (Should we kill the grey squirrel to save the red?), supported by an online learning environment. Students’ written arguments, classroom discussions, and classroom observations were collected and analysed. The findings suggest that even though the two classes engaged with the same learning environment, the decisions and justifications provided by the pairs in the two classes were quite distinct. The students used the evidence from the learning environment in ways which supported their decision, and tended to ignore evidence if these contradicted their decision. Furthermore, students’ justifications support the hypothesis that their decision was based on whether they identified with the actors of the issue. Implications for research include exploring how students identify with the actors of a SSI to enable us to support them overcoming their personal narratives and becoming critical evaluators of scientific knowledge.     

An Investigation of Students’ Personality Traits and Attitudes toward Science

The purposes of this study were to validate an instrument of attitudes toward science and to investigate grade level, type of school, and gender differences in Taiwan’s students’ personality traits and attitudes toward science as well as predictors of attitudes toward science. Nine hundred and twenty‐two elementary students and 1,954 secondary students completed the School Student Questionnaire in 2008. Factor analyses, correlation analyses, ANOVAs, and regressions were used to compare the similarities and differences among male and female students in different grade levels. The findings were as follows: female students had higher interest in science and made more contributions in teams than their male counterparts across all grade levels. As students advanced through school, student scores on the personality trait scales of Conscientiousness and Openness sharply declined; students’ scores on Neuroticism dramatically increased. Elementary school and academic high school students had significantly higher total scores on interest in science than those of vocational high and junior high school students. Scores on the scales measuring the traits of Agreeableness, Extraversion, and Conscientiousness were the most significant predictors of students’ attitudes toward science. Implications of these findings for classroom instruction are discussed.     

Perceptions of Communication With Gay and Lesbian Family Members: Predictors of Relational Satisfaction and Implications for Outgroup Attitudes

This study investigates perceptions of family communication among members with different sexual identities. Specifically, from the perspective of heterosexual family members (N = 129), the study takes an intergroup perspective to determine how accommodative and non-accommodative communication and attitudes toward homosexuality predict intergroup anxiety and relational satisfaction with gay or lesbian family members. Further, the manner in which family communication influences attitudes toward homosexuality is examined. Results are discussed in terms of implications for research on heterosexual–homosexual interaction, family communication, and intergroup communication, in general.     

Farmers’ Attitude towards a Participatory Research Method Used to Evaluate Weed Management Strategies in Bananas

Abstract

In this study, farmers were engaged in a participatory research project and their attitudes evaluated. The purpose was to identify the characteristics of farmers who are favourably predisposed towards meaningful participation in the process. Several cover crops were tested for possible use in the management of watergrass (Commelina diffusa), a noxious weed in banana cultivation. Small, limited-resource farmers were exposed to the essentials of systematic research through a process of experiential learning using participatory techniques. Thirty-six farmers evaluated three cover crops against the current weed control practice of farmers, which served as the control. Farmers and researchers collaborated on the experimental design, treatment allocation, data to be collected and the form of the analysis. Summary data were subjected by the farmers to the Overlap Test to evaluate differences among the treatments. Results indicated that one cover crop, Desmodium heterocarpon, was better than the others in controlling watergrass. These results were confirmed by ANOVA.

A Likert-type scale, used to assess farmers’ attitude, showed that overall, farmers were generally favourable towards the process. Differences in responses to attitudinal statements were based mainly on farmers’ differing education levels. Some level of attrition was experienced in this process, mainly by the older and more experienced farmers. The younger, less experienced farmers completed the trials to a large extent. The results provide useful information for the selection of farmers to be involved in future participatory technology development initiatives.     

Preservice physical education teachers' attributes related to teaching a student labeled ADHD

This study assessed the association between preservice teacher-related variables [i.e., age, adapted physical education (APE) and special education (SPED) coursework, experience teaching students with disabilities and perceive competence] on measures of the Physical Educators' Intention toward Teaching Individuals with Disabilities II – Preservice Survey (PEITID-II-PS). The PEITID-II-PS used the Theory of Planned Behavior (TpB) ( Ajzen, 2002) on preserive physical education teachers (n = 213) purposely selected from universities in China, Korea, and the United States. Results indicated that both intention and perceived behavioral control were predicted by teaching experience and perceived teaching competency. Attitude toward the behavior variable was predicted by prior teaching experience, special education coursework, and age. Age and perceived teaching competency were associated with behavioral beliefs.
