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.

Description
This study examines the effectiveness of two modes of exercise on self-efficacy (SE) in adolescents with Down syndrome (DS). Thirty-nine participants were randomly divided into a voluntary cycling group (VC) (i.e., self-selected cadence), an assisted cycling group (ACT) (i.e., at least 30% faster than self-selected cadence accomplished by a motor),

This study examines the effectiveness of two modes of exercise on self-efficacy (SE) in adolescents with Down syndrome (DS). Thirty-nine participants were randomly divided into a voluntary cycling group (VC) (i.e., self-selected cadence), an assisted cycling group (ACT) (i.e., at least 30% faster than self-selected cadence accomplished by a motor), or a no exercise group (NC). In each cycling intervention the participant completed 30 minute cycling sessions, three times per week for a total of eight weeks. Two subsets of the Physical Activity and Self Efficacy Survey were administered prior to cycling (i.e., pretest) and after the eight week intervention (i.e., post-test). The results were consistent with the hypothesis that self-efficacy would improve after ACT, however there was not improvement after the VC condition as hypothesized. It was also hypothesized that exercise perception would improve following the ACT intervention; execise perception showed a trend of improvement after ACT, but the data did not reach significance. Limitations include the wide variability of the DS population. This limitation is responsible for the variation in mental age seen in the intervention groups and could be responsible for the non-significance of the exercise perception data. To generalize our results for parents, therapists, teachers, etc., our recommendation is for persons with DS to participate in physical activity that is easy for them at first \u2014 a simplified sport or active game, assisted cycling, brisk walking \u2014 so that they have a positive experience with exercise. Showing individuals with DS that they can be proficient exercisers will likely improve their self-efficacy and motivate them to engage in more PA over time. In conclusion, eight weeks of moderate ACT exercise demonstrated a significant trend for improved self-efficacy in adolescents with DS.

This study examines the effectiveness of two modes of exercise on self-efficacy (SE) and exercise perception (EP) in adults with Down syndrome (DS). Thirteen participants attended four sessions: a baseline assessment, an Assisted Cycling Therapy (ACT) session, a resistance training (RT) session, and a session of no training (NT). In the baseline assessment, 1-repetition max (1RM) measurements and voluntary pedal rate measurements were taken. In the cycling intervention, the participant completed 30 minutes of assisted cycling at 35 percent greater than their voluntary pedaling rate. In the resistance training session, 2 sets of 8-12 repetitions of the leg press, chest press, seated row, leg curl, shoulder press, and latissimus pulldown were performed. During the session of no training, participants played board games with student researchers for 35 minutes.Two subsets of the Physical Activity and Self Efficacy Survey were administered prior to each session (i.e., pretest) and after the intervention (i.e., post-test). The results were consistent with the hypothesis that ACT would lead to higher SE than RT or NT. However, ACT did not lead to higher EP than RT or NT as hypothesized. Additionally, it was hypothesized that RT would lead to higher SE and EP than NT, but the results did not support this. In conclusion, an acute session of ACT demonstrated a significant trend for improved self-efficacy in adults with DS.

Adolescent survivors of sex trafficking are at risk for poor health outcomes and may be less likely to adopt healthy lifestyle behaviors such as physical activity. Survivors of childhood traumas may be less likely to engage in physical activity due to lack of self-efficacy. The present study was a case-series of a pre-post, single-arm physical activity intervention to test whether the program could increase self-efficacy among adolescent survivors of sex trafficking. The intervention was 8-weeks of 60-minute aerobic physical activity classes offered three times per week at a residential center for adolescent girls who are survivors of sex trafficking and sexual abuse. The primary outcome was physical activity-related self-efficacy as measured by the Sport Competence subscale of the Physical Self Perception Profile (PSPP) questionnaire. Secondary outcomes included self-reported physical activity, emotional eating, and sleep habits. All outcomes were measured at baseline, 4 weeks, and 8 weeks. Five participants were enrolled in the study. Two participants experienced an increase in the Sport Competence subscale of the PSPP Questionnaire by Week 4 of the study and then a decrease by Week 8 of the study. Another participant experienced no change in the Sport Competence subscale score. Scores for the last two participants could not be determined due to invalid data. These findings suggest that more research is needed on enhancing healthy behaviors among adolescent sex trafficking survivors.

The primary goal for this study is to assess and develop an understanding of the effects of Assisted Cycling Therapy (ACT) on self-efficacy and exercise perception of children with Down syndrome (DS). ACT is a stationary bicycle that has a mechanical motor that moves the pedals 35% faster than their self-selected rate. This intervention continued for 30 minutes 2x/week for 8 weeks. A total of seven participants were assessed through the study, however, due to a variety of limitations only two participants completed pre and post testing questionnaires. Our results showed that self-efficacy improved following ACT. Both participants experiences improvement in their total self-efficacy score. However, only one participant showed improvement in exercise perception following the intervention. Interpretations of our results are analyzed in consideration with behavioral limitations that may be present within children with DS. Additionally, these results provided guidance for future research. These include alterations to the intervention time period, as well as the sample size of the study.
