Understanding primary teachers’ professional learning and practice: an activity theory lens     

Goodnough Karen 《课程研究杂志》2019,51(3):362-383

In this study, the author reports on the professional learning of three primary teachers who engaged in three cycles of collaborative action research over a three-year period from 2013 to 2016. Case study was chosen as a methodology to gain insight into the context of the teachers’ work as they interacted with others and adopted multiple tools. Data collection and analysis were on-going over a three-year period, using several sources, including classroom observations, interviews, portraits and teacher-created multimedia artefacts. Cultural-Historical Activity Theory (CHAT) and its activity system unit of analysis (subject, object, tools, norms, community and division of labour) was used by the author to describe changes in the professional learning of the three teachers, the contradictions or tensions they addressed, and how they transformed the aspects of their professional knowledge and classroom practice.  相似文献   

Pathways to Parental Engagement: Contributions of Parents,Teachers, and Schools in Cultural Context     

Karen Rattenborg  Aimée Kleisner Walker  Jan Miller-Heyl 《Early education and development》2019,30(3):315-336

Research Findings: This study examined correlates of parents’ reported school engagement in an ethnically diverse, rural sample (N = 346) of parents and teachers in kindergarten through Grade 2. Of particular interest were role expectations and family–school relationships in American Indian families, who historically have been marginalized by schools. In terms of role expectations, parents and teachers agreed that they should support each other’s roles, parents should have more responsibility than schools for teaching social skills, and families and schools should have shared responsibility for children’s academic success. Teachers had higher expectations than parents for parent engagement, which in turn was greater when parent–teacher communication was more frequent and the school climate was more welcoming. American Indian parents more strongly endorsed a separation of family and school roles and felt less welcomed at school; ethnicity moderated correlates of reported parent engagement. Practice or Policy: These findings have practical promise given that parent–teacher communication, school climate, and role expectations are more easily altered than are structural barriers that also may hinder parents’ involvement in supporting their children’s early education.  相似文献

A survey of school psychologists' perspectives and practices with childhood depression     

Harvey F. Clarizio  Karen Payette 《Psychology in the schools》1990,27(1):57-63

Despite some controversy, there is an emerging body of knowledge regarding the nature, prevalence, assessment, and treatment of childhood depression. The following study was undertaken to determine how this knowledge compares with the perceptions and practices of school psychologists in two north central states. A need for school psychologists to define the concept of childhood depression is identified. Use of DSM III-R for the diagnosis of childhood depression in the schools and the inclusion of standardized measurement techniques in the assessment process are advocated. Involvement of school psychologists in the treatment process, either directly or indirectly, is also recommended.  相似文献   

Responses to oral glucose challenge differ by physical activity volume and intensity: A pilot study     

Trevor N. Simper  Cecile Morris  Anthony Lynn  Ciara O'Hagan  Karen Kilner 《运动与健康科学(英文)》2020,9(6):645-650

BackgroundOne-hour postprandial hyperglycemia is associated with increased risk of type 2 diabetes and cardiovascular disease. Physical activity (PA) has short-term beneficial effects on post-meal glucose response. This study compared the oral glucose tolerance test results of 3 groups of people with habitually different levels of PA.MethodsThirty-one adults without diabetes (age 25.9 ± 6.6 years; body mass index 23.8 ± 3.8 kg/m²; mean ± SD) were recruited and divided into 3 groups based on self-reported PA volume and intensity: low activity < 30 min/day of moderate-intensity activity (n = 11), moderately active ≥ 30 min/day of moderate-intensity PA (n = 10), and very active ≥ 60 min/day of PA at high intensity (n = 10). Participants completed an oral glucose tolerance test (50 g glucose) with capillary blood samples obtained at baseline, 15 min, 30 min, 45 min, 60 min, 90 min, and 120 min post-ingestion.ResultsThere were no significant differences between groups for age or body fat percentage or glycated hemoglobin (p > 0.05). The groups were significantly different in terms of baseline glucose level (p = 0.003) and, marginally, for gender (p = 0.053) and BMI (p = 0.050). There was a statistically significant effect of PA on the 1-h postprandial glucose results (p = 0.029), with differences between very active and low activity groups (p = 0.008) but not between the moderately active and low activity groups (p = 0.360), even when baseline glucose level and gender differences were accounted for. For incremental area under the curve there was no significant effect of activity group once gender and body fat percentage had been accounted for (p = 0.401). Those in the low activity group took 15 min longer to reach peak glucose level than those in the very active group (p = 0.012).ConclusionThe results suggest that high levels of PA have a beneficial effect on postprandial blood glucose profiles when compared to low and moderate levels of activity.  相似文献

Anthropometric characteristics of Columbia, South Carolina, youth baseball players and Dixie Youth World Series players     

French KE  Spurgeon JH  Nevett ME 《Research quarterly for exercise and sport》2007,78(3):179-188

The purpose of this study was to compare measures of body size in two samples of youth baseball players with normative data from the United States National Center for Health Statistics (NCHS) growth charts. One sample of youth baseball players participated in a local little league. The second sample of youth baseball players were members of eight of the twelve teams participating in the 1995 Dixie Youth World Series. Normative data for the United States (NCHS) were used as comparative data. Two trained anthropometrists measured standing height, sitting height, lower limb height, upper limb length, arm girth, calf girth, tricep skinfold, and abdomen skinfold on all participants. In both samples, pitchers, short stops, and first basemen were a more highly skilled group and exhibited larger body size (greater standing height, sitting height, lower limb height, upper limb length) than children who played at other positions. The standing height of local little league players was similar to the median of reference data at ages 7, 8, and 9 years. The standing height and weight of skilled players in both samples approximated the 75th percentile for standing height and weight at ages 10, 11, 12, and 13 years. The results suggest that baseball players exhibit larger body size than the normal population at young ages. Body size may be an important criterion used by coaches to select and assign young players to certain positions.  相似文献
