The overall purpose of this collected papers dissertation was to examine the utility of a cognitive apprenticeship-based instructional coaching (CAIC) model for improving the science teaching efficacy beliefs (STEB) of preservice and inservice elementary teachers. Many of these teachers perceive science as a difficult subject and feel inadequately prepared to teach it. However, teacher efficacy beliefs have been noted as the strongest indicator of teacher quality, the variable most highly correlated with student achievement outcomes. The literature is scarce on strong, evidence-based theoretical models for improving STEB. This dissertation is comprised of two studies. STUDY #1 was a sequential explanatory mixed-methods study investigating the impact of a reformed CAIC elementary science methods course on the STEB of 26 preservice teachers. Data were collected using the Science Teaching Efficacy Belief Instrument (STEBI-B) and from six post-course interviews. A statistically significant increase in STEB was observed in the quantitative strand. The qualitative data suggested that the preservice teachers perceived all of the CAIC methods as influential, but the significance of each method depended on their unique needs and abilities. STUDY #2 was a participatory action research case study exploring the utility of a CAIC professional development program for improving the STEB of five Bahamian inservice teachers and their competency in implementing an inquiry-based curriculum. Data were collected from pre- and post-interviews and two focus group interviews. Overall, the inservice teachers perceived the intervention as highly effective. The scaffolding and coaching were the CAIC methods portrayed as most influential in developing their STEB, highlighting the importance of interpersonal relationship aspects in successful instructional coaching programs. The teachers also described the CAIC approach as integral in supporting their learning to implement the new inquiry-based curriculum. The overall findings hold important implications for science education reform, including its potential to influence how preservice teacher training and inservice teacher professional development in science are perceived and implemented. Additionally, given the noteworthy results obtained over the relatively short durations, CAIC interventions may also provide an effective means of achieving improvements in preservice and inservice teachers’ STEB more expeditiously than traditional approaches.

<p>The dissertation includes two independent chapters which investigated the experiences of individuals with disabilities in connection with societal attitudes regarding disability. The first article is a systematized review which analyzes and synthesizes the existing literature on implicit and explicit disability attitudes across multiple domains (e.g., educational; occupational; healthcare). Chapter 1 identifies common themes across the existing literature and identifies potential predictors and buffers of negative disability attitudes. The article concludes with a call to counseling psychologists to address negative disability attitudes utilizing the roles and themes of the field. Finally, suggestions are made regarding the development and implementation of interventions to help address negative disability attitudes and the subsequent harmful effects. </p><p>The second article is an empirical study that examines factors related to the persistence intentions of individuals with disabilities to address the high attrition rates of this population within postsecondary environments. A moderated mediation model is proposed to address four hypotheses. First, I hypothesized academic self-efficacy would mediate the relationship between stereotype threat and persistence intentions. Second, coping self-efficacy would mediate the relationship between stereotype threat and persistence intentions. Third, social self-efficacy would mediate the relationship between stereotype threat and persistence intentions. Fourth, I hypothesized that endorsing a growth mindset would buffer against the negative indirect relationship between stereotype threat and persistence intentions which operate through academic self-efficacy. Data were collected from postsecondary students who identified as having one or multiple diagnosed disabilities at a large public university in the Midwest. The study results supported my first hypothesis that academic self-efficacy would significantly mediate the relationship between stereotype threat and persistence intentions. Additionally, the results revealed that high levels of perceived stereotype threat were associated with lower levels of coping self-efficacy and social self-efficacy, as the researcher anticipated. However, our second and third hypotheses were rejected due to these mediating factors not significantly influencing a participants’ intentions to persist within the academic environment. Finally, the results suggested that one’s mindset of intelligence was a positive main effect predictor of academic self-efficacy. However, contrary to our fourth hypothesis, mindset of intelligence did not significantly moderate the negative indirect relation between stereotype threat and persistence intentions that operate through academic self-efficacy.</p>

Research on self-efficacy has been a productive field and abundant research has shown that teachers’ self-efficacy beliefs influence teachers’ actions and performances and thus affect students’ learning outcomes. However, there is a lack of literature on EFL teachers’ self-efficacy beliefs and even less research was set in Chinese EFL contexts. On the one hand, this study was conducted to provide a general picture of the current status of EFL teachers’ perceived English proficiency, self-rated self-efficacy beliefs and self-reported teaching practices in terms of some demographic perspectives; On the other hand, it aimed to explore the correlations among Chinese primary EFL teachers’ perceived English proficiency, self-efficacy beliefs and teaching practices. The quantitative study surveyed 217 in-service primary EFL teachers. The descriptive results showed that: (1) EFL teachers varied in perceived English proficiency in terms of age, years of teaching experience and college major; (2) age and teaching experience did while college major didn’t make a difference for EFL teachers’ self-efficacy beliefs; (3) the surveyed EFL teachers, in general, had a greater preference to communication-oriented language teaching (COLT) than form-oriented language teaching (FOLT). The results from the correlational statistics showed that: (1) perceived English proficiency (PEP), on the whole, had a significant predictive effect on self-efficacy beliefs (SEB). It was striking that among the four skills (listening, speaking, reading, and writing) of English language, speaking had the most significant predictive effect on self-efficacy beliefs; (2) EFL teachers’ self-efficacy beliefs (SEB) had a predictive effect on COLT practices whereas not on FOLT practices; (3) The mediation model of showing the causal impacts of PEP (through SEB) on COLT was tested. i.e. Chinese primary EFL teachers’ self-efficacy beliefs played a complete mediating role between perceived English proficiency and communication-oriented language teaching. The findings of the present study added on the compelling evidence that self-efficacy beliefs matter in the realm of primary EFL teaching in China. In light of these findings, implications were generated to primary EFL teacher education and in-service EFL teacher training programs, such as courses related to improving English proficiency, especially speaking skills, should be offered for non-English major EFL teachers; training courses related to improving self-efficacy beliefs, especially on classroom management strategies, and the recommended communicative-oriented language teaching practices should be offered to pre-service and inexperienced in-service EFL teachers.
