Using data collected from 4329 students in the 2015 iteration of Trends Mathematics and Science Study (TIMSS), we explore two mediators for relationship between socioeconomic status (SES) TIMSS-results mathematics among Norwegian fifth graders. First, how students’ motivation self-concept mediate SES test results. Second, by using parent reported resources parents’ attitudes to school tested su...

This study aimed to investigate the effect of a training program based on trends in international mathematics and science (TIMSS) developing habits mind mathematical reasoning skills among pre-service math teachers Oman. The sample consisted 24 female divided into two equal groups: experimental control. data was collected by sued test questionnaire that measured level after appropriate validity...

Since the first international comparative study on students’ achievement in the beginning of 1960’s, the interest of countries from all over the world to participate in studies initiated by the International Association for the Evaluation of Educational Achievement (IEA), has been growing rapidly. In the First International Mathematics Study (FIMS, 1964) just 12 countries participated. In TIMSS...

When the International Association for the Evaluation of Educational Achievement (IEA) was established in 1959 the basic idea was to use comparative analysis of country differences in achievement to take advantage of the world as an educational laboratory. A large number of comparative studies involving substantial numbers of countries has since then been conducted and much has indeed been lear...

The traditional approach in analysing IEA data has been to use single-level statistical models. This paper argues that multilevel modelling offers a wider spectrum in analysing IEA data because of multi-stage sampling, since students are nested within classes, classes within schools, and schools within countries. Two illustrative examples are used to provide support to this argument. In the fir...

Recently, performance profiles in reading, mathematics and science were created using the data collectively available in the Trends in International Mathematics and Science Study (TIMSS) and the Progress in International Reading Literacy Study (PIRLS) 2011. In addition, a classification of children to the end of their primary school years was conducted in accordance with these performance types...

Apart from the international comparative data and analysis that International Association for the Evaluation of Educational Achievement (IEA) studies traditionally provide, there is also an opportunity for countries to include national options that may enrich a country’s knowledge in a focus area. This paper reports on research that was conducted by including a national option in IEA’s TIMSS’99...

This study examines the relationship between instructional clarity in physics lessons and students’ motivation self-confidence to learn physics. We conducted a secondary analysis of data from Trends International Mathematics Science Study (TIMSS) 2019. Using six countries, whose science achievement scores were higher than TIMSS 2019 scale centrepoint, this explores relevance by using confirmato...

TIMSS collects a vast amount of information aimed to provide a context to better understand education systems around the globe. This paper discusses how this background information can be reported using three real examples from the 1999 assessment. These examples illustrate the main concepts and steps involved in reporting background data, while presenting methods and statistical techniques tha...
