Survey of Mathematical Opportunity

数学和科学机会调查(SMSO)的目的是：1)制定一种更好的方法来衡量中小学学习科学和数学的机会；2)制定一个分析数学和科学材料的原型课程框架；3)制定一种教师知识的衡量标准；以及4)对衡量教学实践的方法进行探索性研究。这项工作将分三个阶段进行：第一阶段是制定数学和科学内容框架。这项工作将导致原型框架的开发，将用于TIMSS的课程分析。第二阶段是编写编码手册，说明如何将该框架应用于课程材料的方法程序。第三阶段是进行研究和开发，为TIMSS编制调查工具，重点是学习机会(OTL)、教师知识和其他学校教育变量，特别是课堂过程(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).//
