The High Schools That Work school improvement initiative is the nation's largest comprehensive school reform model with over a thousand schools adopting its framework. The initiative's premise is that all students can meet the demands of a college preparatory curriculum if provided the right supports. Analyzing over a decade of data on student course taking and performance, we employ a rigorous comparative interrupted time series strategy to assess the extent to which HSTW meets its goal by increasing students’ successful progression through the mathematics and science pipelines. Each pipeline consists of three college preparatory courses: algebra 1, geometry, and algebra 2 in mathematics and biology plus two physical science courses in science. The results show no effect on pipeline progression for the average student and some evidence of increased gaps in course taking between more advantaged and disadvantaged students. 相似文献

Conceptualisations of literacy and literacy practices for children with severe learning difficulties
Literacy is traditionally narrowly conceptualised as a set of skills related to accessing and generating written or printed text. For children designated as having severe learning difficulties (SLD), who are unlikely to develop these ‘conventional’ literacy skills, such a conception implies their semi‐literacy or nonliteracy. Although conceptions of multimodal literacy and multiliteracies have rarely been applied to this group, broader understandings of literacy that include a range of activities, modes and media provide greater opportunities for including these learners in literacy practices. Drawing upon our research with teachers of this group of children and young people, we illustrate these literacy practices. We note, however, that such practices are often haphazard, not coherently thought through, and that there is much confusion regarding any distinction between communication and literacy. We argue for literacy as a specific form of communication, but conclude that broader models of literacies should be utilised to guide and support practitioners in developing interactive practice and in making reasoned and principled approaches and decisions about literacy practices, routes and progression for children with SLD. 相似文献

Abstract. Thirty‐four matched pairs of sixth‐ and seventh‐grade students were selected from 358 participants in a comparison of an explicit concrete‐to‐representational‐to‐abstract (CRA) sequence of instruction with traditional instruction for teaching algebraic transformation equations. Each pair of students had been previously labeled with a specific learning disability or as at risk for difficulties in algebra. Students were matched according to achievement score, age, pretest score, and class performance. The same math teacher taught both members of each matched pair, but in different classes. All students were taught in inclusive settings under the instruction of a middle school mathematics teacher. Results indicated that students who learned how to solve algebra transformation equations through CRA outperformed peers receiving traditional instruction on both postinstruction and follow‐up tests. Additionally, error pattern analysis indicated that students who used the CRA sequence of instruction performed fewer procedural errors when solving for variables. 相似文献
