Students' socioeconomic status (SES), school climate, and students' attitudes stand out as important factors that determine academic achievement. The current study investigated the relationship among SES, attitude toward science, school climate, and academic achievement comparatively in terms of countries. Trends in International Mathematics and…

This study compares the successes of numbers 94 7th grade students in science education with assessment-evaluation questions based on skill and acquisition. Assessment-evaluation achievement tests based on skill and acquisition were developed by researchers towards the measurement of force and acquisitions in friction units taking place in the…

Since 1995, the International Association for the Evaluation of Educational Achievement (IEA) implemented the Trends in International Mathematics and Science Study (TIMSS) as an international comparative study. This article aims at identifying the correlations of science classroom instructions with TIMSS science achievement of eighth graders among…

Automated scoring of free drawings or images as responses has yet to be used in large-scale assessments of student achievement. In this study, we propose artificial neural networks to classify these types of graphical responses from a TIMSS 2019 item. We are comparing classification accuracy of convolutional and feed-forward approaches. Our…

Results of the TIMSS 2019 reveal that Kosovar students have lower achievement levels in both mathematics and science. In understanding this gap in achievement, it is of value to take a closer look at factors that may influence student learning. Results of this analysis reveal that factors such as home and school resources influence achievement…

This research proposes a new statistic for testing latent variable distribution fit for unidimensional item response theory (IRT) models. If the typical assumption of normality is violated, then item parameter estimates will be biased, and dependent quantities such as IRT score estimates will be adversely affected. The proposed statistic compares…

Previous research on the implications of early-tracking education systems has not specifically focused on how studying in academic and non-academic tracks shapes the features and characteristics of shadow education (private tutoring) that students are involved in. The study compares the scale and features of private tutoring and the underlying…

We set out to address the question--what does it mean for educational knowledge to be 'powerful'? We compare the Anglo tradition of curriculum studies with the "Didaktik" tradition through the lens of an analysis of curriculum structure in postgraduate courses in South African universities rooted in either the Anglo or…

The purpose of this study is to comparatively investigate the science teaching curricula in Turkey, which have undergone changes four times since the millennium. For this purpose, we carried out a technical and taxonomic examination of the learning outcomes listed in the science curricula that were introduced in 2000, 2005, 2013, and 2017…

This study finds that, breaking with decades of slow improvement, U.S. reading and math scores on the National Assessment of Educational Progress (NAEP) and other assessments have seen historic declines since most states implemented national Common Core English and math curriculum standards six years ago. This descriptive analysis is designed to…

Is it possible to compare the results in assessments of mathematics across countries with different curricula, traditions and age of starting school? As part of the iPIPS project, a Russian version of the iPIPS baseline assessment was developed and trial data were available from about 300 Russian children at the start and end of their first year…

Item response theory (IRT) has so many advantages than its precedent Classical Test Theory (CTT) such as non-changing item parameters, ability parameter estimations free from the items. However, in order to get these advantages, some assumptions should be met and they are; unidimensionality, normality and local independence. However, it is not…

The 2015 Trends in International Mathematics and Science Study (TIMSS) involved 57 countries and 43 different languages to assess students' achievement in mathematics and science. The purpose of this study is to evaluate whether items and test scores are affected as the differences between language families and cultures increase. Using…

The aim of this study was to examine the association between students' TIMSS (Trends in Mathematics and Science Study) science achievement, and students' school achievements, in terms of national tests and grades from school years 6 and 9. Further to examine the association with TIMSS science achievement and different subgroups of students based…

Over the past few decades, researchers, policy makers, educators and the general public, who have an interest in mathematics education in different countries, pay a great deal of attention to the results from international comparative studies. Of great interest to the international studies is the results of Eastern students consistently achieving…
