Conceptual knowledge and self-efficacy are two research topics that are well-established at universities, however very little has been investigated about these at the community college. A sample of thirty-seven students enrolled in three introductory circuit analysis classes at a large southwestern community college was used to answer questions about conceptual knowledge and self-efficacy of community college engineering students. Measures included a demographic survey and a pre/post three-tiered concept inventory to evaluate student conceptual knowledge of basic DC circuit analysis and self-efficacy for circuit analysis. A group effect was present in the data, so descriptive statistics were used to investigate the relationships among students' personal and academic characteristics and conceptual knowledge of circuit analysis. The a priori attribute approach was used to qualitatively investigate misconceptions students have for circuit analysis. The results suggest that students who take more credit hours score higher on a test of conceptual knowledge of circuit analysis, however additional research is required to confirm this, due to the group effect. No new misconceptions were identified. In addition to these, one group of students received more time to practice using the concepts. Consequently, that group scored higher on the concept inventory, possibly indicating that students who have extra practice time may score higher on a test of conceptual knowledge of circuit analysis. Correlation analysis was used to identify relationships among students' personal and academic characteristics and self-efficacy for circuit analysis, as well as to investigate the relationship between self-efficacy for circuit analysis and conceptual knowledge of circuit analysis. Subject's father's education level was found to be inversely correlated with self-efficacy for circuit analysis, and subject's age was found to be directly correlated with self-efficacy for circuit analysis. Finally, self-efficacy for circuit analysis was found to be positively correlated with conceptual knowledge of circuit analysis.

This is a qualitative study about sources of self-efficacy and roles of assistive technologies (AT) associated with the science, technology, engineering and mathematics (STEM) choice and participation of STEM professionals and graduate students with sensory and orthopedic disabilities. People with disabilities are underrepresented in STEM, which can be traced back along the STEM pipeline to early undergraduate participation in STEM. Little research exists, however, about pathways and factors associated with successful STEM participation for people with disabilities at any point along their trajectories. Eighteen STEM professionals and graduate students with sensory and orthopedic disabilities were interviewed for this study. Sources of self-efficacy were sought from interview transcripts, as were emergent themes associated with the types, uses and roles of AT. Findings suggest that people with sensory and orthopedic disabilities weigh sources of self-efficacy differently from white males without disabilities in STEM and more like other underrepresented minorities in STEM. Social persuasions were most frequently reported and in far more detail than other sources, suggesting that this source may be most impactful in the development of self-efficacy beliefs for this group. Additionally, findings indicate that AT is critical to the successful participation of people with sensory and orthopedic disabilities in STEM at all points along their STEM pathways. Barriers center around issues of access to full engagement in mainstream STEM classrooms and out of school opportunities as well as the impact of ill-informed perceptions about the capabilities of people with disabilities held by parents, teachers and college faculty who can act as gatekeepers along STEM pathways. Gaps in disability specialists' knowledge about STEM-specific assistive technologies, especially at the college level, are also problematic. The prevalence of mainstream public school attendance reported by participants indicates that classroom teachers and disability-related educators have important roles in providing access to STEM mastery experiences as well as providing positive support and high expectations for students with disabilities. STEM and disability-based networks served to provide participants with role models, out of school STEM learning experiences and important long-term social connections in STEM communities.

Learning a second language has been shown to have many benefits, but in the

state of Arizona the teaching and learning of second languages has been restricted since the passing of Proposition 203. In the past few years, schools offering Dual Language Immersion programs have emerged, but their teachers do not have much experience, training or resources to teach language through content. Language immersion self- efficacy has been shown to be crucial for the teachers to be more effective in their instruction and for them to embrace the challenges they face.

The purpose of this action research study was to increase Spanish immersion teachers' self-efficacy through a community of practice, in which teachers performed peer observations and offered feedback, collaboratively drew from a pool of resources that were available online for all to use, and supported each other in the areas they felt could be improved.

Quantitative data included pre- and post- intervention self-efficacy surveys, as well as a retrospective survey. Qualitative data included audio recordings and field notes from the community of practice sessions, teacher observations, peer observations, and feedback meetings, as well as interviews.

Results from the analysis of data showed an increase of teachers’ self-efficacy because of the close collaboration and resource sharing that took place during the implementation of the community of practice. Teachers also reported positive changes in practice due to peer observations and collegial conversations during meetings, where teachers could acknowledge their own successes and use ideas from others to improve their practice. Finally, despite all the positive outcomes from this action research study, it was evident there were some systemic issues the community of practice could not change, such as the lack of resources and appropriate curriculum for Spanish immersion teachers.

Many parents and educators have agreed our students should have the opportunity of becoming bilingual to face global competition more effectively. Because of that, Spanish immersion schools have been growing in popularity in Arizona. Moreover, it has become clear that as we have more schools and teachers willing to adopt these programs, more resources must be made available to support immersion teachers and their instruction.
