TIMSS 2019 International Database: Grade 4 - Trends in International Mathematics and Science Study

Trends in International Mathematics and Science Study 2019
TIMSS 2019 marks the seventh cycle of the study and provides 24 years of trends. Conducted every four years since 1995, TIMSS has been a valuable tool for monitoring international trends in mathematics and science achievement at the fourth and eighth grades.
TIMSS 2019 reported overall achievement, as well as extensive background information on the home and school contexts in which teaching and learning mathematics and science take place. Like the previous TIMSS assessments (conducted in 1995, 1999, 2003, 2007, 2011, and 2015), TIMSS 2019 collected detailed information about curriculum and curriculum implementation, instructional practices, and school resources.
From the 2019 cycle onwards, an innovative computerized version of TIMSS enables countries to investigate complex areas of the mathematics and science framework that are difficult to measure with traditional paper and pencil tests. eTIMSS is an engaging, interactive assessment that encompasses the content of the paper-and-pencil version of TIMSS while also integrating problem solving and inquiry tasks designed to stimulate student motivation through items that simulate real world contexts and laboratory situations. In 2019, countries could opt to administer the paper-based version of TIMSS. The next cycle of TIMSS will be administered in 2023.

《2019年国际数学与科学趋势研究》（Trends in International Mathematics and Science Study 2019，简称TIMSS 2019）是该研究的第7轮调查，累计提供了24年的趋势观测数据。该研究自1995年起每四年开展一次，长期以来都是监测四年级与八年级学生数学、科学学业成就国际趋势的重要工具。
TIMSS 2019不仅报告了整体学业成就水平，还收录了数学与科学教与学所处的家庭与校园环境的多维度背景信息。与此前1995、1999、2003、2007、2011及2015年的TIMSS测评一致，TIMSS 2019同样收集了关于课程设置、课程实施、教学实践以及校园资源的详细信息。
自2019轮次起，创新的电子化TIMSS版本使各参与国得以探究传统纸笔测试难以衡量的数学与科学测评框架中的复杂领域。电子化TIMSS（eTIMSS）是一款兼具趣味性与交互性的测评工具，它既覆盖了纸笔版TIMSS的全部内容，还融入了问题解决与探究类任务：这些任务通过模拟真实世界场景与实验室情境设计题目，以激发学生的参与动机。2019年，各参与国可选择采用纸笔版TIMSS开展测评。TIMSS的下一轮调查将于2023年实施。
