Third International Mathematics and Science Study: International Curriculum Analysis, 1992-1995

The International Curriculum Analysis (ICA) study provided curricular and textbook information from each country participating in the Third International Mathematics and Science Study (TIMSS). TIMSS was a comparative study of education in mathematics and the sciences conducted in over 40 countries on five continents. The goal of TIMSS was to measure student achievement in mathematics and science in participating countries and to assess some of the curricular and classroom factors that are related to student learning in these subjects. The study was intended to provide educators and policy makers with an unparalleled and multidimensional perspective on mathematics and science curricula; their implementation; the nature of student performance in mathematics and science; and the social, economic, and educational context in which these occur. Below is a description of each of the types of data files found in this study. The Textbook Specific and Curriculum Guide Specific data files contain overall characteristic information, the number of pages, size of book, publisher, etc. pertaining to material used within a country for all countries involved in the study. The General Topic Trace Mapping data files contain questionnaire responses for each specific science and mathematics topic for each grade. The Document Description data file contains document ID, name, subject, publisher and publishing data for each document provided by each country in the study. The Unit Level data files contain information describing a specific unit within a document, used for both textbooks and curriculum guides. The Block Level data files contain specific curricular information about the blocks contained within each unit. The Textbook Coverage data files contain summaries of context coverage for each country's textbooks and the performance expectation codes of those textbooks, both Mathematics and Science. The coverage rate for each content topic is expressed as the average percent that particular topic is mentioned in each of the country's textbooks. The Textbook Characteristics data file contains derived variables from 400 textbooks used in 45 countries. The variables captures the frequency with which content material such as activities, exercise or question sets, instructional narratives and other instructional tools, as well as performance expectation related material are found within these textbooks.

国际课程分析（ICA）研究提供了来自参与第三次国际数学与科学研究（TIMSS）的每个国家的课程和教科书信息。TIMSS是一项在五大洲超过40个国家进行的数学与科学教育比较研究。TIMSS的目的是衡量参与国学生在数学和科学方面的成绩，并评估与这些学科学生学习相关的某些课程和课堂因素。该研究旨在为教育工作者和政策制定者提供对数学和科学课程、其实施、学生在数学和科学方面的表现性质以及这些现象发生的社交、经济和教育背景的无与伦比的多维度视角。以下是对本研究中每种数据文件类型的描述。教科书特定和课程指南特定数据文件包含有关各国在研究中使用的所有材料的总体特征信息、页数、书籍大小、出版社等。一般主题追踪映射数据文件包含每个年级每个具体科学和数学主题的问卷回答。文档描述数据文件包含每个国家在研究中提供的每个文档的文档ID、名称、科目、出版社和出版数据。单元级别数据文件包含描述文档中特定单元的信息，用于教科书和课程指南。块级别数据文件包含关于每个单元中包含的块的特定课程信息。教科书覆盖范围数据文件包含每个国家教科书的背景覆盖总结和那些教科书的绩效预期代码，涵盖范围以每个内容主题在每个国家教科书中被提及的平均百分比表示。教科书特征数据文件包含来自45个国家的400本教科书的派生变量。这些变量捕捉了活动、练习或问题集、教学叙事和其他教学工具等教学内容以及与绩效预期相关的材料在这些教科书中的出现频率。
