An experimental interdisciplinary freshman course called The Systems Approach to the Universe was taught at North Carolina State University in the Spring of 1986. The goals of the course were to introduce principles of general systems theory; to provide examples through lectures and readings of applications of these principles in a wide variety of fields and disciplines; and to introduce and provide practice in critical questioning and evaluation. This paper outlines what was done, how it worked, and how the instructors and the students assessed the experience afterwards.He received his B.Ch.E. from the City College of New York, and his Ph.D. in chemical engineering from Princeton University. Barbara A. Soloman is Coordinator of Advising for the Academic Skills Program and Lecturer in the University Studies Program at North Carolina State University. She received her B.S. in mathematics from the City College of New York and her M.S. in mathematics from North Carolina State University.  相似文献

A post hoc matching design was used to compare children who participated in the Home Instructional Program for Preschool Youngsters (HIPPY) throughout Arkansas to children from the same classrooms who had no preschool experience and children who had other preschool experiences in the third and sixth grades. The program showed modest positive impact on school suspensions, grades, classroom behavior, and achievement test scores at both grade levels.  相似文献

Conclusion As you can see, this is a rather holistic view. These categories may have to be expanded depending on the particular needs of your task. However, it seemed to be efficient. This process may also be applicable to other situations such as student papers. This was my attempt to compare texts with a minimal amount of bias. I welcome input of others in an effort to expand and refine this rubric.  相似文献

Data on perinatal and early childhood somatic and psychological risk factors of a random sample of children were gathered in early to middle childhood and employed to examine the long-term risk of emotional and behavioral problems of late childhood and adolescence. 3 issues were addressed: First, can syndromic specificity of such effects be identified on scaled and diagnostic measures of syndromes? Second, are these effects attributable to excess risk of low-income children for both perinatal and later childhood problems? Third, are the intervening mechanisms identifiable as intellectual impairment, vulnerability to poor health, poor maternal caretaking, maternal rejection, or maternal stress associated with marital problems? Findings indicated that elevated risk was present for all syndromes, both at the scale level and at the diagnostic level. None of the examined intervening mechanisms fully accounted for the effects of early risks.  相似文献

Acknowledging the affective in higher education   总被引:1,自引:0,他引:1  
This article argues that we need richer conceptions of students as affective and embodied selves and a clearer theorisation of the role of emotion in educational encounters. These areas are currently under‐researched and under‐theorised in higher education. The first part of the article explores the literature on emotion. The second reports on a case study which aimed to map students' emotional journeys over their first year at university. These data highlight the importance of relationships, students' changing emotions over the year, their perceptions of their academic studies and understandings of life at university. The article concludes that it is important to understand the affective dimension in pedagogic encounters and the lifeworld of students, and that it is possible to do so without a collapse into therapeutic discourses.  相似文献

Spelling skills have been identified as one of the major barriers to written text production in young English writers. By contrast oral language skills and text generation have been found to be less influential in the texts produced by beginning writers. To date, our understanding of the role of spelling skills in transparent orthographies is limited. The current study addressed this gap by examining the contribution of spelling, oral language and text generation skills in written text production in Italian beginner writers. Eighty-three children aged 7–8 years participated in the study. Spelling, lexical retrieval, receptive grammar, and written sentence generation and reformulation skills were assessed and children were asked to write a text on a set topic. A factor analysis revealed that the children’s written text production was captured by three factors: productivity, complexity and accuracy. In contrast to results from children learning to write in opaque orthographies, such as English, this study showed that receptive grammar and written sentence generation skills accounted for significant variance in measures of productivity, complexity and accuracy in Italian children’s written text production. Spelling skills contributed to text accuracy and quality and explained more variance than receptive grammar in microstructural accuracy. By contrast, oral grammatical skills explained more variance in text quality than spelling. The current study shows the differential impact of language systems, such as Italian, on written text production. Implications for assessment and instruction are outlined.  相似文献
