Analysis and Data Preparation for the Second International Science Study

这一建议是对数据分析的延伸， 第二次国际科学研究。 SISS是一个 1983年对24个国家进行的国际调查。 的 1986年，由于贫困， 1983年学校的参与率。 后来 对SISS数据的分析产生了一份报告“科学 在十七个国家取得的成就”， 交易的关注，主要是因为相对较差 美国学生在科学成就方面的表现。 在这项拨款下，我们会深入分析 解释科学成就的各种因素 国家 其中一些因素涉及科学课程， 其结构（综合与分层饼法），以及 学习的机会和对可以学到多少的估计 甚至是最底层的25%的学生。 这一点和大量的家庭作业对 成就和在职培训，参与科学 项目、课程规划和 教师将接受检查。 还有其他变量的影响 与学校组织，如学校和班级规模有关， 接受检查。 该项目/定于1989年6月提交的报告应 对学生成绩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的变革， 教学 该项目得到了国家 科学基金会和美国教育部。

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.
