Biology is well suited for mathematical description, from the perfect geometry of viruses, to equations that describe the flux of ions across cellular membranes, to computationally intensive models for protein folding. For this short Web review, however, I’m going to focus on how mathematics helps us as biologists sort, evaluate, and draw conclusions about our data. Just as computer technology ...

Among the countries that participated in trends international mathematics and science study (TIMSS) 2019 for grade 8 science, Oman had highest gender gap favor of girls. The current explores achievement relates it to students’ varying perceptions their own attitudes capabilities. sample comprised 467 9 students, 266 female 201 male. participants were given a TIMSS-like test, along with four sel...

This study aims to analyze students' critical thinking skills in solving TIMSS questions on Geometry content seen from the extrovert personality Class VIII Junior High School. The research method used is descriptive qualitative by involving six students, each of which three students with who are classified as low, medium and high abilities subjects. data collection carried out were questionnair...

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...
