This article assesses the effects of Tulsa, Oklahoma's early childhood education programs on social-emotional outcomes, examining teacher ratings of children's behavior from the Adjustment Scales for Preschool Intervention and a measure of attentiveness using fixed effects regressions with propensity score matching. The sample includes 2,832 kindergarten students in 2006, of whom 1,318 participated in the Tulsa Public Schools (TPS) pre-K program and 363 participated in the CAP of Tulsa County Head Start program the previous year. Program participation was associated with lower timidity and higher attentiveness for TPS pre-K alumni and a marginally significant reduction in timidity for Head Start alumni. Results were similar for the free lunch-eligible subsample. We conclude that high-quality, school-based preschool programs can enhance social-emotional development.  相似文献

ABSTRACT

This article reports on an effort by the authors to use usability testing as a component of online teacher training for their multimajor technical communication course. The article further explains the ways in which program administrators at other institutions can create their own usability testing protocols for formative online teacher training in course design and in principles of user-centered design.  相似文献

An examination of artifacts provides insights into the goals, practices, and orientations of the persons and cultures who created them. Here, we analyze storybook texts, artifacts that are a part of many children's lives. We examine the stories in books targeted for 4–8-year-old children, contrasting the texts generated by Native American authors versus popular non-Native authors. We focus specifically on the implicit and explicit ‘epistemological orientations’ associated with relations between human beings and the rest of nature. Native authors were significantly more likely than non-Native authors to describe humans and the rest of nature as psychologically close and embedded in relationships. This pattern converges well with evidence from a behavioral task in which we probed Native (from urban inter-tribal and rural communities) and non-Native children's and adults' attention to ecological relations. We discuss the implications of these differences for environmental cognition and science learning.  相似文献

ABSTRACT

This paper presents a step-by-step conversion of a face-to-face (F2F) entry level social work research methods course to a computer-mediated format. An overview of teaching practices and the important pedagogical foundations associated with this curricular effort are discussed followed by an introduction to the electronic platform utilized in the course. Five new teaching practices that guide the F2F-to-online course conversion of this introductory research methods course are presented with corresponding teaching activities and technological tools. A conversion matrix aligns the teaching practices, classroom activities, and provides references for the identified tools.  相似文献

Four groups of subjects: normal healthy normotensive nonpregnant women (Group A), normal normotensive pregnant women (Group B), women with preeclamptic toxaemia (Group C) and eclamptic women (Group D): with fifty subjects in each group, were investigated for serum lipid profile in the third trimester of pregnancy. There was significant increase in serum triglyceride and VLDL cholesterol leve as well as decrease in LDL cholesterol in normal pregnancy, while total cholesterol and HDL cholesterol levels did not show any statistically significant alteration. The preeclampsia (Group C) was associated with a significant rise in triglyceride and VLDL cholesterol and fall in HDL cholesterol concentration, while eclamptic women showed significant fall in HDL cholesterol and rise in LDL cholesterol as compared to normal pregnant women. However, interestingly, elevation of the ratios of total cholesterol: HDL cholesterol and triglyceride: HDL cholesterol as well as diminuition of the ratio of HDL cholesterol: VLDL cholesterol showed statistical significance in pregnancy induced hypertension in both Groups C and D, while eclamptic women showed significant elevation of LDL cholesterol: HDL cholesterol ratio in addition.  相似文献
