TIMSS 2019 International Database: Grade 8 - 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》（TIMSS）是该研究的第7个周期，覆盖了24年的趋势数据。该研究自1995年起每四年开展一次，TIMSS一直是监测四年级与八年级学生数学、科学学业表现国际趋势的重要工具。
TIMSS 2019不仅公布了整体学业表现数据，还收录了数学与科学教与学活动所处的家庭与校园环境的详尽背景信息。与此前1995、1999、2003、2007、2011及2015年开展的TIMSS测评一致，TIMSS 2019收集了课程设置、课程实施、教学实践以及校园资源的详细信息。
自2019年研究周期起，创新的计算机化TIMSS（eTIMSS）使各国得以探究传统纸笔测试难以测评的数学与科学测评框架中的复杂领域。eTIMSS是一款兼具趣味性与交互性的测评形式，既覆盖纸笔版TIMSS的全部测评内容，又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的试题，激发学生的学习动机。2019年，各国可选择采用纸笔版TIMSS进行测评。TIMSS的下一周期测评将于2023年开展。
