Information systems researchers that apply critical social perspectives frequently emphasize the potential for information technology to serve as a mechanism for increased rationalization, domination, and control. Such theorists often overlook or discount the liberating aspects of information systems. In this study, we apply the ideal of rational discourse developed by Jürgen Habermas to the phenomenon of Wikipedia in an effort to explore empirically the emancipatory potential of information systems. We contend that Wikipedia embodies an approximation of the necessary conditions for rational discourse. While several challenges persist, the example of Wikipedia illustrates the positive potential of information systems in supporting the emergence of more emancipatory forms of communication. The corresponding implications for researchers and design professionals alike are discussed. 相似文献

This paper describes results from field testing of middle-school math formative assessments alongside professional development and instructional resources. We employed a randomised, controlled design to address the question: Does using our formative assessment strategies improve student performance on assessments of key mathematical ideas relative to a comparison group? This study also provided data on the instructional sensitivity of the assessments, which is part of the validation needed for formative assessments. Teachers were recruited from two districts and seven middle schools. Nineteen treatment and 17 comparison group teachers and their students were included in study analyses. Scores on extended response and short-answer questions indicated that students in the treatment group performed better than students in the comparison group who received the formative assessments alone. These findings demonstrate both the feasibility and value of including performance task-types in a brief assessment context. 相似文献

This article provides an extended, comprehensive example of how teachers, schools, districts, and external factors (e.g., parental pressure and policy mandates) shape curriculum research in the U.S. It retrospectively examines how three different middle school curriculum units were implemented and scaled‐up in a large, diverse school system. The curriculum materials were cognitively based, hands‐on, guided inquiry units; each focused on a different “big idea” in science. The units met some criteria for instructional strategies rated by the Project 2061 Curriculum Analysis. Using evidence‐based decisions, two of the units were found to be effective and equitable, and went to scale, but one was not effective. However, the course of scale‐up was also affected by a changing policy climate, and proceeded in unpredictable ways, with small scale effects not found at large scale, and experienced teachers less effective than inexperienced teachers. Four years after funding ended, none of the units were sustained within the school district. The interactions between the demands of the units and of the school district's policy environment suggests reasons why this occurred, despite evidence that two of the units were successful with diverse learners. © 2012 Wiley Periodicals, Inc.

Theory and past research argue for the importance of understanding the effect of various campaign communication forms (e.g., newspapers, television news, radio, debates, candidate advertising, and personal discussions) on levels of issue knowledge (IK). This study used a meta-analytic approach to examine how well these forms predict IK. The aggregate analysis indicates that any of these forms can affect IK but that the different forms are not equally successful. Findings also indicate that the level of campaign interest moderates the effect of reading newspapers and watching television news and that those who watch debates in years with incumbents are less likely to learn. In addition, studies of newspapers are less likely to find significant effects in recent years, even though the issue content of newspapers has increased. The findings also suggest that television news is more likely to influence IK when levels of issue content are greater. These data indicate that measures of media use and IK can systematically influence the study results. Several conclusions are drawn from the research in the hopes of moving toward a theoretical model of communication forms and the attainment of IK. 相似文献

To support the national and international aims of inclusion, special teacher training in Sweden was replaced in 1990 by special educator training. These special educators would supervise the teachers in their school and would not exclusively teach students. The aim of this study was to investigate what the principals of 14 municipal compulsory schools in Stockholm County thought about the organisation and realisation of special education in 1996 and 2006 respectively. According to the results, there were fewer segregated groups in these schools in 2006, but an increasing number of students were placed in segregated groups that were common to several schools or municipalities. Principals at schools with teaching teams usually saw the special educator as a coordinating and supervising resource while others preferred the special teacher function. The former approach led to a more inclusive school and the latter in the direction of exclusion. 相似文献
