Examination of TIMSS Mathematics Data with Multilevel Measurement Models in Respect to Content, Cognitive and Topic Areas

Abstract

This research study aims to identify TIMMS 8th grade mathematics item groups and the specification of items in which Turkish 8th grade students have signıfıcantly lower level of correct responses compared to all other 8th grade participants. For this purpose, total 260 (82 from 1999, 88 from 2007, and 90 from 2011) items released by International Association for the Evaluation of Educational Achievement (IEA) were grouped according to cognitive, content and sub-content domains. Then, mean correct responses of released items for each participant country were obtained from IEA’s yearly almanac. Finally, data were analyzed by using Multilevel Measurement Models and differences in achievement levels between Turkish 8th graders and their peers from other participating countries were predicted and tested in the context of item groups. Analysis of data showed that performance of Turkish students statistically significantly lower than performance of students from rest of the other participant countries in Number (Content Domain)-Fractions and Decimals (Topic Area)-Knowing (Cognitive Domain) item group. Detailed investigation revealed that students generally fail in procedures in fractions and conversions among fraction, decimal, and percent.
