Trends in International Mathematics and Science Study, 2011
Add to My BasketDescription
The Trends in International Mathematics and Science Study, 2011 (TIMSS 2011) is a study that is part of the Trends in International Mathematics and Science Study (TIMSS) program; program data are available since 1999 at https://nces.ed.gov/pubsearch/getpubcats.asp?sid=073. TIMSS 2011 (https://nces.ed.gov/timss/) is a cross-sectional study that provides international comparative information of the mathematics and science literacy of fourth- and eighth-grade students and examines factors that may be associated with the acquisition of math and science literacy in students. The study was conducted using direct assessments of students and questionnaires for students, teachers, and school administrators. Fourth- and eighth-graders in the 2010–11 school year were sampled. The study's response rate was 94 percent. Key statistics produced from TIMSS 2011 are mathematics and science achievement scores of U.S. fourth- and eighth- grade students compared to that of students in other countries.
Detailed Methodology
The international desired target population is all students enrolled in the grade that represents 4 or 8 years of schooling. The sample design employed by the TIMSS 2011 assessment is generally referred to as a two-stage stratified cluster sample: the first stage involves sampling schools and the second involves selecting classrooms within sampled schools. TIMSS guidelines call for a minimum of 150 schools to be sampled per grade, with a minimum of 4,000 students assessed per grade. In the United States, a sample of 450 schools was drawn at 4th-grade and 600 schools at 8th-grade.
