The golden lady: the storied life of a multilingual teacher and author of supplemental reading materials in a marginalized South African language

Personal narratives can be powerful venues for understanding human experiences. In this paper, we tell the story of Lutanyani, a Black South African multilingual teacher and author of supplemental reading materials in a marginalized South African language. Through various word images, we convey the role of language, in particular written language, in Lutanyani’s life. For Lutanyani, writing serves as ‘a healing process’ in two ways: (1) as a linguistically empowering venue that affirms and shifts his linguistic identity from outsider to insider, and (2) as a backward‐ and forward‐looking means to reconcile his past and reconstruct a message of hope for intermediate‐grade students throughout South Africa. This study has implications for classroom practices in the USA as well as development work in international settings.     

Association of leisure time and occupational physical activity with obesity and cardiovascular risk factors in Chile

ABSTRACT

The aim of this study was to investigate the association between physical activity (PA), both occupational (OPA) and during leisure time (LTPA), with obesity and cardiovascular risk factors in Chilean adults. 5,157 participants from the Chilean National Health Survey 2009–2010 were included in this study. OPA and LTPA levels were assessed using the Global Physical Activity Questionnaire. The association between both PA with obesity and cardiovascular risk factors was determined using logistic regression. Our findings showed a significant trend between higher LTPA and lower odds for obesity (OR 0.64 [95% CI: 0.53; 0.76], central obesity 0.52 [0.44; 0.61]) and other cardiovascular risk factors including diabetes (OR: 0.72 [0.55; 0.94]), hypertension (OR: 0.59 [0.50; 0.71]) and metabolic syndrome (OR: 0.62 [0.50; 0.78]). In contrast, OPA was only associated with lower odds of diabetes (OR: 0.79 [0.65; 0.98]) and hypertension (0.85 [0.74; 0.98]). In conclusion, LTPA was associated with a lower risk of all major cardiovascular risk factors, whereas OPA was only associated with a lower risk of diabetes and hypertension.     

Reliability of a Protocol for Testing Endurance Performance in Runners and Cyclists

This study examined stability and reliability of free-living physical activity assessed by pedometer in 69 young female college students (M age = 18.7 years, SD = 1.2, range: 18-25 years; body mass index = 23.2 kg/m², SD = 0.6) for two complete weeks (Week 1 and Week 2) separated by 12 weeks. During Week 1, participants took an average of 8,880 steps/day, SD = 3,219, range: 1,858-19,480; during Week 2 9,088 steps/day, SD = 3,299, range 1,736-16,837; t (68) = -.568, p = .572. In both weeks, only Sunday differed significantly (repeated measures analysis of variance; Week 1: p < .0001; Week 2: p < .01) from all other days of the week. The computed intraclass correlation between weeks was moderate (.72). Group mean pedometer-determined physical activity was stable across 2 weeks separated by 12 weeks in this young, healthy sample of women. Individuals within these groups held their rank order to a moderate extent over time. These findings provide important evidence of the reliability of pedometer-determined physical activity data and are of practical importance to study design.

Educational equity,academic standards,and countercontrol: Preventing academic deficits with supplemental interdependent rewards

School psychologists have been involved with developing and installing individual contingencies designed to remedy individual students' academic deficits. Group-oriented contingencies can be applied to broader efforts designed to prevent learning problems class-wide. Independent group-oriented rewards are frequently used in school settings to enhance learning by rewarding strong academic performance (e.g., reward for each student who maintains a 90% average). Research suggests overreliance on these contingencies may not be educationally equitable because they may be less effective or ineffective in influencing the behavior and learning of students with weaker academic skills. Theoretical and applied research is analyzed which suggests that maintaining ubiquitous independent rewards and providing supplemental interdependent group-oriented bonus rewards may allow educators to a) maintain their academic standards, b) enhance educational equity by improving learning in students who may not respond to typical independent group-oriented rewards, and c) enhance classroom climates. Also, recommendations are provided that may allow educators to mitigate concerns over perceived unfairness associated with interdependent group-oriented rewards.

VIOLENCE DIRECTED AGAINST TEACHERS: RESULTS FROM A NATIONAL SURVEY

Teachers in U.S. schools report high rates of victimization, yet previous studies focus on select types of victimization and student perpetrators, which may underestimate the extent of the problem. This national study was based on work conducted by the American Psychological Association Classroom Violence Directed Against Teachers Task Force and is one of the few national studies to examine violence directed at teachers. Participants included 2,998 kindergarten through 12^th‐grade (K‐12) teachers from 48 states who completed an anonymous web‐based survey assessing their experiences with victimization. Results revealed that 80% of teachers reported at least one victimization, and of these teachers, 94% reported being victimized by students. Nearly three‐fourths of all teachers experienced at least one harassment offense, more than half experienced property offenses, and 44% reported physical attacks. Findings suggest that specific teacher and community characteristics are associated with a higher likelihood of victimization, namely, male gender and urban settings; whereas, African American teachers were less likely to report victimization. Implications for teacher training, school interventions, public policy, and future research are discussed.     

Training Tech Services’ Student Employees Well: Evidence-based Training Techniques in Conjunction with Coaching and Mentoring Strategies

Librarians in higher education who work in technical services must frequently rely on student employees to accomplish tasks previously assigned to professional staff. Hiring, training, managing, and mentoring student workers for the performance of high-level library functions can prove challenging. However, working side-by-side with student employees can be a positive experience when evidence-based training techniques and effective coaching and mentoring strategies are utilized. This article focuses on training techniques integrated with ongoing coaching and mentoring strategies to promote a positive work environment and motivated, successful student employees.     

Activities to Teaching Electric Field Based on Physics by Inquiry

We designed and used a series of activities （named activities to teaching electric field （ATEF）） based on the Physics by Inquiry （PBI） strategy to teaching the electric field concept with university students. We used a concentration factor tool to assess the effectiveness of those activities used during three weeks of instruction. Results indicate that students who had traditional teaching obtained a very tiny gain （less than 1%）; concentration factors indicate that most of their responses fall into a random area, which is not favorable. On the other hand, the experimental group using our activities had greater gains （〉 10%） than the control group. Concentration factors showed that after instruction, students＇ mental models changed toward a favorable pattern about comprehension of electric field concept and Coulomb＇s law. A hypothesis test of two samples indicated that there is a significant difference between both traditional teaching and ATEF based on PBI.
