Recently these differences among countries andregions have been attributed to culture- and country-level variables. Thus, the…

Purpose: This study aimed to compare the performance of latent class differential item functioning (DIF) approach and IRT based DIF methods using manifest grouping. With this study, it was thought to draw attention to carry out latent class DIF studies in Turkey. The purpose of this study was to examine DIF in PISA 2015 science data set. Research…

This paper derives efficiency scores for around 8,500 schools in 30 countries, using Programme for International Student Assessment 2012 data and a nonparametric approach called data envelopment analysis as method. On average, achievement scores of schools can be increased by 27%, holding inputs constant. Efficiency scores vary considerably both…

Since the publication of results from the first iteration of testing within the Programme for International Student Assessment (PISA) and the ensuing media consternation and political rhetoric about teacher quality in education systems around the world, professional standards for teachers have been considered, developed and implemented globally in…

The quality of a teacher plays one of the most important roles in the achievement of an education system.

Relational survey model was used. The sample group of the study was…

Measures of variability are successfully used in predictive modeling in research areas outside of education. This study examined how standard deviations can be used to address research questions not easily addressed using traditional measures such as group means based on index variables. Student survey data were obtained from the Organisation for…

Educational quality is defined and shaped by the classroom practices implemented by teachers in our schools. The Teaching and Learning International Survey (TALIS)-PISA link presents a unique opportunity to explore what takes place in the classroom by listening to the voices of teachers and students. Teachers, with their professional training and…

The purposes of this study were to compare the differences in the use of geometry in elementary school mathematics textbooks among Finland, Mainland China, Singapore, Taiwan, and the USA and to investigate the relationships between the design of the textbooks and students' performance on large-scale tests such as TIMSS-4 geometry, TIMSS-8…

This study offers a comparative analysis of questions found in Turkish, Singaporean, and American mathematics textbooks and workbooks based on topics covered in the 8th grade mathematics curriculum in Turkey. To this end, the study utilizes the 3-dimensional framework developed by Li. When the questions in the textbooks and workbooks…

The literature on the immigrant-native educational achievement gap is suggestive of a better performance of immigrant students in countries practising selective immigration policies. However, the origin of such differences has not been investigated. I considered both important observed characteristics as well as the role of unobservables in the…

The Programme for International Student Assessment (PISA) and Trends in Mathematics and Science Study are two highly respected studies of school pupils' academic achievement. English policy-makers have been disappointed with school children's performance on these tests, particularly in comparison to the strong results of young people from East…

This study investigated the relationship between policies related to the recruitment, selection, preparation, and certification of new teachers and (a) the quality of future teachers as measured by their mathematics content and pedagogy content knowledge and (b) student achievement in mathematics at the national level. The study used data…
