Multilevel international data have been released from the Third International Mathematics and Science Study (TIMSS), providing an opportunity to apply multilevel modeling techniques in educational research. In this paper, TIMSS factors are classified in fixed and random categories according to the project design. Classifying fixed and random…

Reviews the evolution of existing debates over international achievement comparisons with emphasis on some of the Third International Mathematics and Science Study (TIMSS) responses relevant to educational practitioners. Highlights technical issues in developing free-response items, conducting curriculum analyses, and evaluating videotape findings…

Primary school data from the Third International Mathematics and Science Study (TIMSS) were analyzed in this study to examine performance difference between third and fourth grades. The score comparison was conducted across all TIMSS items in each of the 26 participating countries. The empirical findings indicate that not all TIMSS items have…

Middle school data from the Third International Mathematics and Science Study (TIMSS) are analyzed in this study to compare achievement differences between adjacent grades. To facilitate this computer-based analysis, a Statistical Analysis System (SAS) program has been developed to transpose matrices of the item scores in more than 40 countries.…

An empirical approach is adopted in this paper to explore a possible model for prediction of students' science achievement in China and the United States. Construction of the model is based on the ninth-grade data base from Phase 2 of the Second International Education Association Science Study (SISS) in the United States and the SISS Extension…
