DOI: https://doi.org/10.25828/p0t7-2405 v1.1: Edited, anonymised data for public distribution basic skills education [6.1] educational policy [6.3] International The survey had international coverage Country Individuals and institutions Sample survey data TIMSS 2007 collected detailed information about mathematics and science curriculum coverage and implementation, as well as teacher preparation, resource availability, and the use of technology. A systematic, two-stage probability proportional-to-size (PPS) sampling technique was used, where schools are first sampled and then classes within sampled (and participating) schools. . Because of its large population sizes, it was necessary to include a preliminary sampling stage in the Russian Federation, where regions were sampled first and then schools. Singapore also had a third sampling stage, where students were sampled within classes Participants could exclude schools from the sampling frame if they were in geographically remote regions, were extremely small, offered curriculum or structure different from the mainstream, or provided instruction only to students in the “within-school” exclusion categories. The general TIMSS rules for defining within-school exclusions can be found in the technical documents. Face-to-face [f2f] Each participating country was responsible for carrying out all aspects of the data collection, using standardized procedures developed for the study. Training manuals were created for school coordinators and test administrators that explained procedures for receipt and distribution of materials as well as for the activities related to the testing sessions. These manuals covered procedures for test security, standardized scripts to regulate directions and timing, rules for answering students’ questions, and steps to ensure that identifi cation on the test booklets and questionnaires corresponded to the information on the forms used to track students. The students within each country were selected using probability sampling. A consequence of this is that each student had a known probability of selection. The inverse of this selection probability is the sampling weight. In a properly selected and weighted sample, the sum of the weights for the sample approximates the size of the population. In TIMSS, the sum of the sampling weights for a country sample is an estimate of the size of the population of students within the country in the sampled grade(s). Weighted and unweighted response rates were computed for each participating country by grade, at the school level, and at the student level. Overall response rates (combined school and student response rates) also were computed. TIMSS & PIRLS International Study Center TIMSS & PIRLS International Study Center.
