A gender study investigating physics self-efficacy

The underrepresentation of women in physics has been well documented and a source of concern for both policy makers and educators. My dissertation focuses on understanding the role self-efficacy plays in retaining students, particularly women, in introductory physics. I use an explanatory mixed methods approach to first investigate quantitatively the influence of self-efficacy in predicting success and then to qualitatively explore the development of self-efficacy. In the initial quantitative studies, I explore the utility of self-efficacy in predicting the success of introductory physics students, both women and men. Results indicate that self-efficacy is a significant predictor of success for all students. I then disaggregate the data to examine how self-efficacy develops differently for women and men in the introductory physics course. Results show women rely on different sources of self-efficacy than do men, and that a particular instructional environment, Modeling Instruction, has a positive impact on these sources of self-efficacy. In the qualitative phase of the project, this dissertation focuses on the development of self-efficacy. Using the qualitative tool of microanalysis, I introduce a methodology for understanding how self-efficacy develops moment-by-moment using the lens of self-efficacy opportunities. I then use the characterizations of self-efficacy opportunities to focus on a particular course environment and to identify and describe a mechanism by which Modeling Instruction impacts student self-efficacy. Results indicate that the emphasizing the development and deployment of models affords opportunities to impact self-efficacy. The findings of this dissertation indicate that introducing key elements into the classroom, such as cooperative group work, model development and deployment, and interaction with the instructor, create a mechanism by which instructors can impact the self-efficacy of their students. Results from this study indicate that creating a model to impact the retention rates of women in physics should include attending to self-efficacy and designing activities in the classroom that create self-efficacy opportunities.

L’importance du rendement, du soutien des adultes, des attentes de réussite et de la valeur accordée aux mathématiques dans les choix de filières de formation préuniversitaire des étudiantes issues des séquences de mathématiques enrichies

La présente étude s’intéresse aux choix de filières de formation des filles comparées aux garçons. La présence des filles dans les filières de formation dans le domaine des sciences, de la technologie, du génie et de la mathématique (STGM) est moins importante que celle des garçons. Ce fait est documenté dans la plupart des pays industrialisés (OCDE, 2013). Les décideurs sont préoccupés par cette sous-représentation des filles et des femmes dans ces domaines et s’affairent à comprendre le phénomène, dans le but d’agir pour changer la situation (Drouin et al., 2008; MCCCF, 2011). Or, les facteurs d’influence pour expliquer cet écart entre les garçons et les filles sont nombreux et ne font pas l’objet d’un consensus dans la littérature (Ceci et al., 2009). Toutefois, plusieurs s’entendent pour dire que les mathématiques, importantes dans les profils de formation en STGM, et la façon dont les filles les perçoivent pourraient expliquer, en partie, leurs choix (Rowan-Kenyon et al., 2012 et Wang et al., 2013). Ces auteurs ont aussi suggéré que le contexte social et les croyances des filles au sujet des mathématiques seraient déterminants dans le processus de choix impliquant cette discipline. Un modèle théorique sociocognitif, inspiré par les travaux de Lent et al, (1994-2006), expliquant le processus de choix scolaires et professionnels a permis de conceptualiser les liens entre les déterminants socio-motivationnels spécifiques aux mathématiques. L’objectif général de la présente étude était de mieux documenter l’importance des mathématiques dans les choix de filières de formation menant aux carrières en STGM. Spécifiquement, nous avons examiné les relations entre le rendement en mathématiques, la perception des élèves quant au contexte social (soutien des parents et enseignants), leurs attentes de réussite, la valeur qu’ils accordent aux mathématiques (sentiment d’autoefficacité, anxiété, perception de l’utilité et intérêt) et les choix de filières de formation générale après leur secondaire (sciences humaines sans mathématiques, sciences humaines avec mathématiques, sciences de la santé et sciences pures). Nous avons exploré les distinctions entre les filles et les garçons. Pour ce faire, 1129 élèves finissants ont été questionnés au sujet de leurs motivations en mathématiques et de leurs intentions de formation post-secondaire. Par la suite, une comparaison entre les 583 filles et les 543 garçons a été réalisée par des analyses de régression logistiques multinomiales. Les résultats montrent que plusieurs déterminants permettent de dégager des similitudes et des différences quant aux choix de filières de formation des filles et des garçons. D’abord, il semble que pour la plupart des élèves, filles ou garçons, un rendement élevé et un important soutien des enseignants tel que perçu par les élèves à la fin du secondaire est davantage lié aux choix de filières en sciences pures et en sciences de la santé qu’en sciences humaines avec ou sans mathématiques. Toutefois, le soutien des parents perçu est plus déterminant pour les filles qui choisissent les sciences de la santé que pour les garçons. Le soutien des enseignants perçu est plus déterminant pour les garçons qui choisissent les sciences humaines que pour les filles. Aussi, un faible sentiment d’autoefficacité en mathématiques serait associé au choix de filières en sciences humaines, alors qu’une forte anxiété en mathématiques chez les filles serait associée aux filières en sciences de la santé. Pour les garçons, c’est davantage l’intérêt en mathématiques qui est déterminant pour choisir la filière des sciences pures. La perception de l’utilité des mathématiques est déterminante à la fois pour les garçons et pour les filles qui choisissent les filières de sciences les menant à des carrières en STGM. En somme, nos résultats suggèrent que le soutien en mathématiques de la part des adultes significatifs, tel que perçu par les élèves, est moins prépondérant que les attentes de réussite (sentiment d’autoefficacité et anxiété) et la valeur accordée aux mathématiques (intérêt et utilité perçue) pour comparer les garçons et les filles dans leurs choix de filières. À la lumière des résultats obtenus, il nous semble que l’implantation de mesures, dans les milieux scolaires, pour renforcer le sentiment d’autoefficacité des jeunes filles en mathématiques et surtout pour diminuer leur taux d’anxiété dans cette matière serait une voie prometteuse pour atteindre la parité entre les garçons et les filles dans les filières en STGM.

Changes in Preservice Teachers’ Self-Efficacy: From Science Methods to Student Teaching

The purpose of this research was to assess preservice teachers self-efficacy at different stages of their educational career in an attempt to determine the extent to which self-efficacy beliefs may change over time. In addition, the critical incidents, which may contribute to changes in self-efficacy, were also investigated. The instrument used in the study was the Teaching Science as Inquiry (TSI) Instrument. The TSI Instrument was administered to 38 preservice elementary teachers to measure the self-efficacy beliefs of the teacher participants in regard to the teaching of science as inquiry. Based on the results and the associated data analysis, mean and median values demonstrate positive change for self-efficacy and outcome expectancy throughout the data collection period.

The contribution of self-efficacy and depression to disability and work status in chronic pain patients: A comparison between Australian and Brazilian samples

There is evidence that cognitions (beliefs) and mood contribute to physical disability and work status in people with chronic pain. However, most of the current evidence comes from North America and Europe. This study examined the contribution of demographic, pain and psychosocial factors to disability and work status in chronic pain patients in two matched samples from quite different countries (Australia and Brazil). Data were collected from 311 chronic pain patients in each country. The results suggest that although demographic and pain variables (especially pain levels) contribute disability, self-efficacy beliefs made a significant contribution to disability in both samples. Age and educational level also contributed to unemployment in both samples. But there were some differences, with self-efficacy and physical disability contributing to work status only in the Brazilian sample. In contrast, depression was the only psychological risk factor for unemployment in the Australian sample. Catastrophising and pain acceptance did not contribute to disability or unemployment in either sample. These findings confirm key aspects of biopsychosocial models of pain in two culturally and linguistically different chronic pain samples from different countries. They suggest that different chronic pain populations may share more similarities than differences. (C) 2008 European Federation of Chapters of the International Association for the Study of Pain.

Self-efficacy for refusal mediated by outcome expectancies in the prediction of alcohol-dependence amongst young adults

The present study examined the relative importance of outcome expectancies and self-efficacy [1] in the prediction of alcohol dependence [2] and alcohol consumption in a sample of young adult drinkers drawn from a milieu previously reported as supportive of risky drinking. In predicting alcohol dependence, outcome expectancies were found to mediate self-efficacy and the same pattern was found for both males and females. This suggests that male and female drinkers may become more similar as they progress along the drinking continuum from risky drinking to dependent drinking. However, in women, in comparison to men, a greater array of expectancies and self-efficacy scales were found to predict heavy drinking, as measured by quantity and frequency. These results suggest that heavy drinking women are particularly at risk of developing drinking related complications and that preventative education needs to take into account gender differences.

Utilising student profiles in mathematics course arrangements

This thesis develops a method for identifying students struggling in their mathematical studies at an early stage. It helps in directing support to students needing and benefiting from it the most. Thus, frustration felt by weaker students may decrease and therefore, hopefully, also drop outs of potential engineering students. The research concentrates on a combination of personality and intelligence aspects. Personality aspects gave information on conation and motivation for learning. This part was studied from the perspective of motivation and self-regulation. Intelligence aspects gave information on declarative and procedural knowledge: what had been taught and what was actually mastered. Students answered surveys on motivation and self-regulation in 2010 and 2011. Based on their answers, background information, results in the proficiency test, and grades in the first mathematics course, profiles describing the students were formed. In the following years, the profiles were updated with new information obtained each year. The profiles used to identify struggling students combine personality (motivation, selfregulation, and self-efficacy) and intelligence (declarative and procedural knowledge) aspects at the beginning of their studies. Identifying students in need of extra support is a good start, but methods for providing support must be found. This thesis also studies how this support could be taken into account in course arrangements. The methods used include, for example, languaging and scaffolding, and continuous feedback. The analysis revealed that allocating resources based on the predicted progress does not increase costs or lower the results of better students. Instead, it will help weaker students obtain passing grades.

Aerobic exercise in adolescence : self-efficacy and stage of change

The purpose of this cross-sectional exploratory study was to examine the relationships among self-efficacy, stage of change, and exercise behaviour in a sample of younger (Grade 9) and older (Grade 12) adolescents. A secondary objective of this study was to apply the transtheoretical model of Stage of Change, as a measure of intention to change, in order to discover the applicability of the model to an adolescent cohort in relation to exercise behaviour. This five-stage model is a self-report measure of an individual's readiness to adopt a new behaviour (e.g., regular exercise). The transtheoretical model incorporates Bandura's self-efficacy factor, which is purported to be a predictive measure of exercise behaviour and a covariant of stage. Exercise behaviour was measured with the Physical Activity Scale, and the University of Rhode Island Change Assessment Scale (URleA) was used to measure the stage of change and self-efficacy variables. The results of this study indicated significant differences between younger and older adolescents, and between males and females in their exercise behaviour. No significant differences were found for grade and gender on stage of change as measured by either a single-item question or a continuous measure of stage. Although grade and gender subgroups were not significantly different in their self-efficacy, significant interaction was found in the grade*gender variable.

The effects of a general excercise program on task self-efficacy and social physique anxiety in older adults

Older adults represent the most sedentary segment of the adult population, and thus it is critical to investigate factors that influence exercise behaviour for this age group. The purpose of this study was to examine the influence of a general exercise program, incorporating cardiovascular, strength, flexibility, and balance components, on task selfefficacy and SPA in older adult men and women. Participants (n=114, Mage = 67 years) were recruited from the Niagara region and randomly assigned to a 12-week supervised exercise program or a wait-list control. Task self-efficacy and SPA measures were taken at baseline and program end. The present study found that task self-efficacy was a significant predictor of leisure time physical activity for older adults. In addition, change in task self-efficacy was a significant predictor of change in SPA. The findings of this study suggest that sources of task self-efficacy should be considered for exercise interventions targeting older adults.

An analysis of the relationship between self-efficacy and performance in a continuous gymnastic routine

Research has shown a consistent correlation between efficacy and sport performance (Moritz, et aI., 2000). This relationship has been shown to be dynamic and reciprocal over seasons (e.g., Myers, Payment, et aI., 2004), within games (e.g., Butt, et aI., 2003), and across trials (e.g., Feltz, 1982). The purpose of the present study was to examine selfefficacy and performance simultaneously within one continuous routine. Forty-seven undergraduate students performed a gymnastic sequence while using an efficacy measure. Results indicated that the efficacy-performance relationship was not reciprocal; previous performance was a significant predictor of subsequent performance (p < .01; f3s ranged from .44 to .67). Results further revealed significant differences in efficacy beliefs between groups with high and low levels of performance [F (1,571) = 7.16,p < .01]. Findings suggest that high levels of performance within a continuous physical activity task result in higher performance scores and higher efficacy beliefs.

The relationship between self-efficacy, collective efficacy and sport performance in men’s and women’s ice hockey goaltender teams

Past research has shown a positive relationship between efficacy and performance (Feltz & Lirgg, 1998). Feltz and Lirgg (1998) found a positive relationship between efficacy and sport performance in hockey players, however they excluded goaltenders due to their unique position. The present study replicated Feltz and Lirgg (1998) with only goaltenders. Data was collected from 12 goaltenders from three Ontario hockey leagues. Efficacy was measured through an online questionnaire and official game statistics provided the performance measures. Data was collected for 70 games to total of 112 responses. Results of this study revealed non-significant relationships between both self- and collective efficacy and all performance indicators. Results of the present study are not consistent with Feltz and Lirgg’s (1998), however other published research has found a non-significant relationship between efficacy and sport performance (Sitzmann & Yeo, 2013). Therefore, it is possible that goaltender efficacy is not the most influential psychological construct.

The Influence of Attentional Focus on the Self-Efficacy-Performance Relationship in a Continuous Running Task

The self-efficacy-performance relationship in continuous sport tasks has been shown to be significantly reciprocal yet unequal with stronger influences in the performance-to-self-efficacy pathway rather than self-efficacy-to-performance pathway (e.g., LaForge-MacKenzie & Sullivan, 2014b). Bandura (2012) suggested that sociocognitive variables may influence this relationship. Attention as a sociocognitve factor may bias the processing of performance and self-efficacy information (Bandura, 1982, 1997; Bandura & Jourden, 1991). As confidence and attention are important aspects of peak running performance (Brewer, Van Raalte, Linder, & VanRaalte, 1991), the primary purpose of the present study was to examine the self-efficacy-performance relationship under three conditions of attentional focus. The secondary purpose was to examine self-efficacy and performance as separate constructs under the same conditions of attention. Participants ran continuously for one kilometer in one of three randomly assigned attentional focus conditions: internal-focus (n = 51), external-focus (n = 50), and control (n = 49). Self-efficacy was assessed using a one-item measure every 200 meters. Path analyses examining the primary objective revealed significant self-efficacy-to-performance pathways in all conditions: external-focus (p < .05, βs ranging from -.17 to -.32), internal-focus (p < .05, βs ranging from -.26 to -.36), and control (p < .05, βs ranging from -.29 to -.42). Significant reciprocal relationships were absent in all conditions. ANOVAs examining the secondary objectives found significantly faster performance in the control condition at the start (F (2, 147) = 3.86, p < .05) and end of the task (F (2, 147) = 3.56, p < .05). Self-efficacy was significantly higher in the internal-focus condition at the end of the task (Self-Efficacy 4 (F (2, 147) = 3.21, p < .05) and Self-Efficacy 5 (F (2, 147) = 4.74, p < .05). In contrast to previous within-trial research (e.g., LaForge-MacKenzie & Sullivan, 2014b) self-efficacy-to-performance effects were more significant and robust than performance-to-self-efficacy effects. These results provided support for Bandura’s (2012) suggestion that sociocognitive factors may have the ability to alter the causal structure of the self-efficacy-performance relationship, proposing complexities in the self-efficacy-performance relationship (Sitzmann &Yeo, 2013). Results were discussed from both theoretical and applied perspectives.

The Impact of Personal Trainer’s Leadership Style on Self-Presentational Concerns, Enjoyment, Task Self-Efficacy and Intention to Exercise in an Introductory Weight Training Orientation

The purpose of the present study was to examine two leadership styles of personal trainers (bland versus enriched) to evaluate their effects on exercise-related outcomes. Participants were 103 university women with no previous experience weight training. Participants were randomly assigned to one of the two leadership style conditions. They completed primary measures prior to being introduced to the personal trainer. Next, participants completed an introductory weight training session, followed by post-manipulation measures. The leadership styles were successfully manipulated. Participants in the enriched leadership style condition reported significantly higher levels of enjoyment and intention to exercise. Participants in the bland leadership style condition reported significantly higher levels of social anxiety; no differences were found for task self-efficacy, self-presentational efficacy, social physique anxiety, or handgrip performance between groups. Thus, an enriched leadership style of personal trainers can increase positive psychological outcomes.
