Description
The benefits of exercise have been recommended in typical and other special populations. However, the evidence for persons with Down syndrome (DS) is still limited. This study was aimed at investigating the impact of an acute bout of aerobic exercise intervention on motor performance, executive function and intrinsic motivation in adolescents and young adults with DS. Ten participants with DS were assigned to an exercise group, who walked on a incremental treadmill protocol for 20 minutes. The exercise intensity was achieved at 66% of their predicted maximum heart rate. Another ten participants with DS were assigned to an attentional control group, who watched a video for 20 minutes. Measures of fine manual dexterity (e.g., Purdue Pegboard test), manual force production (e.g., grip strength test), processing speed (e.g., visual choice reaction time test), verbal processing (e.g., verbal fluency test), attention shifting ability (e.g., The Dimensional Card sorting test), and inhibitory control (e.g., Knock and Tap test) were tested pre and post intervention. An intrinsic motivation scale (e.g., enjoyment and effort) was conducted after the intervention. First, results showed participants significantly improved their performance in manual force production and Knock and Tap Test after the exercise intervention. While it has been proposed that exercise increases arousal status, neurotransmitters, or cerebral vasculature, the exact mechanisms in persons with DS are still unknown. However, our results showed that after treadmill walking, motor and cognitive improvements can be found in individuals with DS, even in a single exercise session. In addition, participants reported higher scores in enjoyment after video viewing than exercise, which may a result from musical effect or too much emphasis on external rewards in their early participation in exercise. These may imply that participants had low intrinsic motivation to an active lifestyle. Further, scores in effort were significantly higher after exercise than video viewing, which indicated their capabilities to perceive their physical exertion. However, other motivational regulations (e.g., introjected and identified regulations) have shown the relationship with exercise behavior in this population. Thus, further study should consider divergent motivational factors in order to implement an effective exercise program.

Description
More Math Minutes is an action research study, set in a high school in the southwestern United States, designed to examine the effects of collaborative peer-group learning for low-performing Algebra I and low-performing Algebra II students. This study is grounded in Social Cognitive Theory and Constructivist Theory including Bandura’s self-efficacy theory and Vygotsky’s theory of proximal development. Participants are comprised of 20 low-performing Algebra I students as the peer-learners and 20 low-performing Algebra II students as the peer-teachers participating in a peer tutoring intervention. Quantitative and qualitative data was collected through pre- and post-self-efficacy questionnaires, pre- and post-mathematics knowledge assessments, semi-structured student interviews, photo-voice, and observations. A concurrent mixed methods design was used to analyze both types of data simultaneously. Results identified the experimental peer-teachers mathematical performance was impacted more than that of the peer-learners. Students were also more motivated to learn mathematics and to seek assistance from peers. The peer-teachers had a significant increase of self-efficacy for self-regulated learning and acknowledged learning occurred for both the peer-teachers and the peer-learners as a result of the peer instruction intervention.

Description
This action research study focused on training for teacher mentors and teacher mentor self-efficacy. Specifically, this project explored the impact participation in a teacher mentor training program and teacher mentor peer shadowing had on teacher mentor self-efficacy. While there is a plethora of literature on teacher self-efficacy, minimal literature exists on the self-efficacy of teacher mentors. Bandura’s self-efficacy theory and cognitive and collaborative apprenticeship provided the foundational body of knowledge in order to understand teacher mentors’ experiences.
This study followed thirty-seven teacher mentors through the first half of the Arizona K12 Center’s Professional Learning Series – Mentor Academy Year 1. Teacher mentors were given a pre-survey upon their first day in the training series, a mid-point survey halfway through the semester and a post-survey at the beginning of the following semester. Teacher mentor self-efficacy data was collected from the surveys and analyzed to determine the impact their participation in the training program had on their self-efficacy. Five random teacher mentors were also selected for interviews. This qualitative data were collected to compliment the quantitative survey data. The second part of the study consisted of interviewing six teacher mentors in a local secondary education school district to gauge the impact the peer mentor shadowing program had on their self-efficacy. Quantitative and qualitative data collected provided insights on the impact these supports had on teacher mentor self-efficacy.
The results of this study indicate the challenge and complexities of being a teacher mentor. The data showed that teacher mentors who lacked training prior to or upon initial entry into their new position of teacher mentor struggled to be effective which negatively affected their self-efficacy. The data also indicated that teacher mentors who participated in the Arizona K12 Center’s mentor training program had greater self-efficacy for their roles. Finally, teacher mentors participating in peer mentor shadowing opportunities found it to be of the greatest impact leading to stronger self-efficacy.

Description
Previous research has found improvements in motor and cognitive measures following Assisted Cycle Therapy (AC) in adolescence with Down syndrome (DS). Our study investigated whether we would find improvements in mental health in older adults with DS as measured from the Adapted Behavior Dementia Questionnaire (ABDQ), Physical Activity Self Efficacy Scales (PACES), Children's Depressive inventory, which are early indicators of Alzheimer's disease (AD) in persons with Down syndrome. This study consisted of seven participants with Down syndrome between the ages of 31 and 54, inclusive, that cycled for 30 minutes 3 x/week for eight weeks either at their voluntary cycling rate (VC) or approximately 35% faster with the help of a mechanical motor (ACT). Our results were consistent with our prediction that self efficacy improved following ACT, but not VC. However, our results were not consistent with our prediction that dementia and depression were improved following ACT more than VC. These results were interpreted with respect to the effects of exercise in older adults with DS. Future research should focus on recruiting more participants, especially those with deficits in mental health.

Description
This study examines the effect of exercise therapy on a stationary bike on cognitive function, specifically inhibition and set-switching, in adolescents with Down syndrome. 44 participants were randomly divided between the voluntary cycling therapy group (VCT) (i.e., self-selected cadence), assisted cycling therapy group (ACT) (i.e., 30% faster than self-selected cadence accomplished by a motor), and a control group (NC) in which the participants did not undergo any exercise therapy. Both cycling groups rode a stationary bicycle, for 30 minutes, three times a week, for eight-weeks. At the beginning (i.e., pretest) and end (i.e., posttest) of the eight-week session the participants completed tasks to evaluate their cognitive function. They completed three trials of the card sort test (i.e., set-switching) and three trials of the knock-tap test (i.e, inhibition) before and after eight-weeks of cycling therapy. The scores of these tests were analyzed using one-way ANOVA between groups and paired samples t-tests. The results showed that after eight-weeks of cycling therapy the participants in the VCT group performed worse in the knock-tap test, but improved in two trials of the card sort test. The results also showed that the participants in the ACT group performed worse after eight-weeks of exercise therapy in one trial of the card sort test. No significant changes were seen for the control group. Due to the fact that on average the participants in the VCT group cycled with a higher heart rate, our results suggest exercise that significantly elevates heart rate can improve cognitive function, specifically set-switching, in adolescents with Down syndrome.

Description
This study examines cognitive planning in adolescents with Down syndrome (DS) following an 8-week assisted cycling therapy intervention. Forty-three participants were randomly assigned to assisted cycling (AC) (i.e., at least 30% faster than self-selected cadence accomplished by a motor), voluntary cycling (VC) (self-selected cadence), and no cycling (NC) control group. Both AC and VC rode a stationary bicycle three times/week, 30 minutes/session, for eight weeks in duration. Participants completed cognitive testing that assessed cognitive planning at the beginning (i.e., pretest) and end (i.e., posttest) of the 8-week intervention. Consistent with our hypothesis, the results showed that cognitive planning improved following eight weeks of cycling for the AC group. The same results were not seen for individuals in the VC or NC groups. Our results suggest that assisted cycling therapy may induce permanent changes in the prefrontal cortex in adolescents with DS.

Description
This study examines the effectiveness of two modes of exercise on depression 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 (AC) (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. The Children's Depression Inventory II was administered prior to cycling (i.e., pretest) and after the eight week intervention (i.e., posttest). Although the data did not reach conventional levels of statistical significance, the results of the study demonstrated partial support for our hypothesis that adolescents with DS showed improvements in depression as measured by the Children's Depression Inventory II following assisted cycling, but not following eight weeks of voluntary cycling. In other words, eight weeks of moderate AC exercise demonstrated a trend for improved depression in adolescents with DS.

Effects of Assisted Cycle Therapy on Short Term and Working Memory in Adolescents with Down Syndrome
Description
To examine the effect of an 8-week cycling intervention on short term and working memory in adolescents with Down syndrome (DS), participants were divided into Assisted Cycling Therapy (ACT), Voluntary Cycling (VC), or No Cycling (NC) groups. Forward and backward digit span assessments were administered prior to and after the intervention to evaluate short term and working memory respectively. 8 weeks of exercise via ACT showed a trend toward conventional levels of significance in the number of levels completed in the backward direction.

Description
This study examined the effect of an 8-week exercise intervention on functional exercise capacity in adolescents with Down syndrome (DS). Forty participants were randomly assigned to one of three groups: assisted cycling (ACT) (n = 17) where participants experienced at least a 35% increase in their voluntary cycling speed through the use of a motor, voluntary cycling (VC) (n = 15) where participants cycled at a self-selected cadence, and no cycling (NC) (n = 8) where participants did not participate in any cycling intervention. In each cycling intervention, each participant completed three, 30 minute cycling sessions per week for a total of eight weeks. The Six-Minute Walk Test (6MWT) was administered prior to and after the 8-week intervention in pre-test and post-test assessment sessions, respectively. Our hypothesis was somewhat supported in that functional exercise capacity improved after ACT as measured by an increase in total number of laps walked, total distance walked, and average walking speed during the 6MWT, when compared to VC or NC.

Does assisted cycle therapy influence activities of daily living in older adults with Down syndrome?
Description
The aim of this study is to examine the relationship between Assisted Cycle Therapy, leisure time activity levels, fine motor control, and grip force in older adults with Down syndrome (DS), all of which affect activities of daily living (ADL) and therefore quality of life. This is relevant because this particular group is at risk for developing early onset Alzheimer's disease (AD), which presents itself uniquely in this population. The parent or guardian of six participants with DS completed Godin's Leisure Time Exercise Questionnaire and the participants themselves completed Purdue Pegboard and grip force assessments before and after an 8-week exercise intervention. The results were inconsistent with past research, with no change being seen in fine motor control or grip force and a decrease being seen in leisure activity. These findings are indicative of the importance of the effect of fatigue on leisure activity as well as maintaining elevated heart rate throughout exercise interventions.
