A system is simply a collection of things connected together. Systems thinking refers to the habit of concentrating on how these collections act, and interact, together. Usually we are particularly concerned with how effective they are in the pursuit of certain goals.  相似文献

Several studies concluded that deep reflection is infrequently reached in student portfolios. An explanation for these disappointing conclusions might be that motivation for portfolio reflection determines the quality of reflection. This study aimed to examine the relationship between motivation for using digital portfolios and reflection. Participants were 156 eleventh-grade students in secondary education, whose motivation for composing a digital portfolio was measured by the motivation part of the Motivated Strategies for Learning Questionnaire. Portfolios of 37 of the 156 students were examined in terms of the amount and nature of reflection by means of a coding scheme based on Mezirow's model of transformative learning. On average, one-fifth (19.5%) of the paragraphs in a portfolio contained reflection, and paragraphs with deep reflection were hardly found (0.8%). It was concluded that motivation for composing a portfolio was fair, but not related to the amount and nature of reflection. This exploratory study gives rise to further research into factors that might influence the quality of portfolio reflection.  相似文献

The school desegregation narrative often references historically white public schools as sites of massive resistance and historically white private schools as segregationist academies. Yet some historically white elite private schools or independent schools, such as The Westminster Schools (plural in name only), established in 1951 in Atlanta, Georgia, chose to desegregate. Such elite institutions, which have served as one catalyst for the creation and maintenance of social and cultural capital, became more accessible after Brown v. Board of Education through a combination of private and public decisions galvanized by larger social, political, and federal forces. Westminster's 1965 decision to consider all applicants regardless of race was emblematic of the pragmatic desegregation politics of Atlanta's city leaders during the civil rights movement and a national independent school agenda focused on recruiting black students. Drawing on institutional, local, regional, and national archival records and publications, this article examines the import of schools like Westminster to civic and business leaders, to the politics of race and desegregation occurring in large cities, and to the range of educational opportunities available in metropolitan areas. This examination yields an analysis of the leadership and politics of a southern historically white elite private school that black students desegregated in 1967.  相似文献

Ten inclusive middle school social studies classes, including 133 general education students, and 24 students with mild disabilities (21 with learning disabilities and 3 with emotional disabilities), were assigned at random to a traditional instruction condition, or an experimental condition involving classwide peer tutoring with specialized materials and parent training. After 18 weeks of instruction, posttest data revealed that students in the experimental condition gained significantly more than students in the traditional instruction condition. These effects were observed on content included in the tutoring intervention, as well as on related content that was taught but not included in the tutoring intervention. Results are discussed within the context of recent research on inclusive secondary content area instruction.  相似文献
