In this research, we consider how the instructional strategies of public school teachers interact with the achievement levels of their students. Slightly more than 1,000 teachers in schools broadly representative of public schools in the USA responded to a school climate survey. Of this number, data from 426 teachers were subjected to Rasch scaling analysis, resulting in profiles of classroom instructional activities interrelated to the skill levels of students. Analyses revealed interesting "uncommonalities" in instructional emphasis, in number as well as kind. Instruction in low achieving classrooms generally was less coordinated than in classes of average achieving students. Instructional strategies and lesson focus in classes of high achieving students were linked in ways that resulted in more continuity and greater productivity.  相似文献

Media Effectiveness in a Malaysian Park System   总被引:1,自引:0,他引:1  
Abstract

The effectiveness of three media formats (guides, booklets, and signs) were compared for use on a nature trail at Kinabalu Park, Malaysia. Based on a multiple-choice, cognitive test taken by 1,194 visitors, the guide treatment scores were significantly higher than the other media treatments. There was no difference between booklet and sign treatments, and all the media treatments scored higher than the control group (F 3,1190 = 173.76, α = .05). A second experiment compared only booklet and sign media. There was still no difference in effectiveness (Paired t test, t = 0.22, df = 566, p □ .05). The first language and educational backgrounds of visitors influenced media effectiveness. However, age, sex, residence, interest level, prior knowledge, and prior park visitation did not influence the relatively great effectiveness of the guide treatment. Other factors, such as cost, time, and numbers served, may justify use of media formats other than guides.  相似文献

In 1965 the authors conducted an experiment in a public elementary school, telling teachers that certain children could be expected to be “growth spurters,” based on the students' results on the Harvard Test of Inflected Acquisition. In point of fact, the test was nonexistent and those children designated as “spurters” were chosen at random. What Rosenthal and Jacobson hoped to determine by this experiment was the degree (if any) to which changes in teacher expectation produce changes in student achievement. Robert Rosenthal is professor of social psychology at Harvard University. Lenore Jacobson is an elementary school principal in the South San Francisco Unified School District.  相似文献
