Patterns of verbal communications between a teacher and student can influence the classroom environment, quality of the instructional program, and student management in the classroom. This study examined teacher-student communication patterns in both regular and special education classes for behaviorally and emotionally handicapped students. It was expected that special class communication patterns would differ substantially from those used in regular classes. Those communications would result in more effective student management and more time on-task for learning. Webster's (1984, 1986) Process Interaction Model was used to analyze the communication patterns. Expected differences between how regular and special class teachers interact with students were not found. Implications of findings are discussed in relationship to teacher training, teacher effectiveness, and classroom management.  相似文献

BackgroundIndividuals with diabetes have greater central arterial stiffness, wave reflections, and hemodynamics, all of which promote the accelerated cardiovascular pathology seen in this population. Acute aerobic exercise has been shown to be an effective strategy for reducing central arterial stiffness, wave reflections, and hemodynamics in healthy individuals; however, the effects of acute aerobic exercise in reducing these outcomes is not well established in people with diabetes. Recently, implementation of high-intensity interval exercise (HIIE) has shown superior improvements in cardiovascular health outcomes when compared to traditional aerobic exercise. Yet, the effect of HIIE on the aforementioned outcomes in people with diabetes is not known. The purpose of this study was to (i) describe the central arterial stiffness, wave reflections, and hemodynamic responses to a bout of HIIE and moderate-intensity continuous exercise (MICE) in adults with diabetes; and (ii) compare the effects of HIIE and MICE on the aforementioned outcomes.MethodsA total of 24 adult men and women (aged 29–59 years old) with type 1 (n = 12) and type 2 (n = 12) diabetes participated in a randomized cross-over study. All participants completed the following protocols: (i) HIIE: cycling for 4 × 4 min at 85%–95% of heart rate peak (HRpeak), interspersed with 3 min of active recovery at 60%–70%HRpeak; (ii) MICE: 33 min of continuous cycling at 60%–70%HRpeak; and (iii) control (CON): lying quietly in a supine position for 30 min.ResultsA significant group × time effect was found for changes in central systolic blood pressure (F = 3.20, p = 0.01) with a transient reduction for the HIIE group but not for the MICE or CON groups. There was a significant group × time effect for changes in augmentation index at a heart rate of 75 beats/min (F = 2.32, p = 0.04) with a decrease following for HIIE and MICE but not for CON. For all other measures of central arterial stiffness and hemodynamics, no significant changes were observed (p > 0.05).ConclusionA bout of HIIE appears to lead to a greater transient reduction in central systolic blood pressure than the reduction observed following MICE; however, both HIIE and MICE improved augmentation index at a heart rate of 75 beats/min in people with diabetes. There was no significant difference in response to HIIE and MICE in all outcomes. This provides preliminary evidence on the role of HIIE on such outcomes in people with diabetes.  相似文献

Schools are required to develop policies and practices in line with the principles of both partnership with parents and pupil participation. However, there is increasing recognition of the potential tensions that may exist between these two principles. This paper reports on a study that aimed to explore the question of how schools might develop their home–school relationships in ways that enhance rather than constrain pupil participation. It focuses on the perspectives of children aged 6 to 16 years (with and without special educational needs), parents and teachers concerning children's involvement in decision-making at home and at school, and their participation within the home–school relationship. The findings highlight the need for schools to develop a coherent view of what active participation means for children and a vocabulary to communicate about this not only with pupils and staff across the whole school, but also with parents. They demonstrate that there is scope for two-way support between parents and teachers in relation to the promotion of children's involvement in decision-making both at home and at school. Further, they illustrate the complex and evolving three-way partnership between parent–child–teacher that is central to the home–school relationship. While it is acknowledged that children may rightly wish to keep a distance between aspects of home and school life, it is argued that there is a need for schools to give explicit consideration to the place of pupil participation within the home–school relationship.  相似文献

The English EAZ experience illustrates the difficulties of developing an innovative, responsive and inclusive curriculum within an evaluative state characterized by high stakes testing. Consequently, while government exhortations to ‘raise standards’, ‘innovate’ and ‘promote social inclusion’ clearly serve an important rhetorical function, they may underestimate the challenges involved and overestimate the capacity of schools within disadvantaged areas to ‘make a difference’.  相似文献
