Analysis and Data Preparation for the Second International Science Study

这项建议是对第二次国际科学研究(SISS)数据分析的延伸。SISS是1983年对24个国家进行的一项国际调查。这项调查于1986年在美国重复进行，因为在1983年的努力中，学校的参与率很低。后来对SISS数据的分析产生了《17个国家的科学成就》报告，该报告受到了极大的关注，主要是因为美国学生在科学成就上的表现相对较差。在这笔赠款下，将对解释各国科学成就的因素进行深入分析。其中一些因素涉及科学课程、其结构(综合与分层蛋糕法)，以及学习的机会和对某些年龄段的学生能学到多少的估计，即使是最贫穷的25%的学生也是如此。本课程还将考察这些因素和家庭作业的数量对成绩和在职培训、参与科学项目、课程计划和教师相对工资的一些影响。还将考察与学校组织有关的其他变量的影响，如学校和班级规模。该项目的报告/计划于1989年6月发布，将对学生在科学方面的成就进行重要的国际分析，这将有助于科学教育工作者和其他人倡导旨在改善科学教学和教学的改革。该项目由美国国家科学基金会和美国教育部联合支持。

This proposal is an extension of analysis of data from the Second International Science Study (SISS). SISS is an international survey of 24 countries conducted in 1983. THe survey was repeated in the U.S. in 1986 because of poor participation rates of schools in the 1983 effort. Later analysis of the SISS data resulted in the report "Science Achievement in Seventeen Countries", which has received a great deal of attention, mainly because of the relatively poor performance of U.S. students in science achievement. Under this grant, in-depth analyses will be conducted on the factors that explain science achievement in the various countries. Some of these factors involve the science curriculum, its structure (integrated vs. layer-cake approach), and the opportunity to learn and an estimate of how much can be learned by certain age levels, even by the bottom 25 percent of students. Some of the effect that this and the amount of homework has on achievement and in-service training, involvement in science projects, the planning of lessons and the relative salaries of teachers will be examined. An the effect of yet other variables to do with school organization such as school and class size will be examined. The report from this project/scheduled for June, 1989 should result in important international analyses of student achievement in science that will be useful to science educators and others in advocating changes designed to improve science instruction and teaching. This project is being supported jointly by the National Science Foundation and the U.S. Department of Education.
