Survey of Mathematical Opportunity

数学与科学机会调查（SMSO） （1）制定更好的科学衡量方法， 小学和中学数学学习机会 2）为学校制定一个原型课程框架， 分析数学和科学材料; 3）制定一项措施 教师知识; 4）进行探索性研究， to measure测量instructional教学practices实践. 这项工作将在三年内完成 阶段： 第一个阶段是数学的发展， 科学内容框架。 这项工作将导致发展 将在课程中使用的原型框架 分析TIMSS。 第二阶段是编写编码手册， 描述框架如何 应用到教材中。 第三阶段是进行研究和开发， 将为TIMSS制作调查工具，重点关注机会 学习能力（OTL）、教师知识和其他学校教育变量， 特别是课堂教学过程（教学实践）。

The survey of mathematics and science opportunity (SMSO) is to: 1) develop a better methodology for measuring science and mathematics opportunity to learn in elementary and secondary schools; 2) develop a prototypical curriculum framework for the analysis of mathematics and science materials; 3) develop a measure of teacher knowledge; and 4) conduct an exploratory study of ways to measure instructional practices. The work will be done in three phases: The first phase is the development of a mathematics and science content framework. This work will lead to the development of prototyical framework that will be used in the curriculum analysis for TIMSS. A second phase is the development of coding manuals which describe the methodological procedures of how the framework would be applied to the curricular materials. The third phase is to conduct research and development that would produce survey instruments for TIMSS focusing on opportunity to learn (OTL), teacher knowledge, and other schooling variables, especially classroom processes (instructional practices).//
