This paper examines the IEA’s Third International Mathematics and Science Study (TIMSS) data for Greece and more specifically POP2 (8th grade). The paper focuses on the teacher’s educational-teaching practices in the classrooms and analyses these with factor analysis. We also investigate the relationship between teaching practices and student achievement with regression analysis. Educational / ...

Taking lower-secondary schooling within the English educational system as an example, this paper illustrates the contribution of two bodies of international scholarship to the scoping of research-based pedagogical development that aims to improve student attitude and achievement in science and mathematics. After sketching the English context of systemic reform, the paper uses findings from the ...

This study investigates the impact of item parameter drift (IPD) on parameter and ability estimation when the underlying measurement model fits a mixture distribution, thereby violating the item invariance property of unidimensional item response theory (IRT) models. An empirical study was conducted to demonstrate the occurrence of both IPD and an underlying mixture distribution using real-worl...

Parental involvement is an emerging issue in education. Many research studies show that when parents are interested in science and involved in science activities, their children’s performance in science increases. According to these research studies, many science educators are concerned with how to improve parents’ engagement in learning science. At the international science competition, U.S.A ...

Although globalization is a term in flux, it is broadly used to describe a world of increased interconnectedness and interdependence. While educationalists have long theorized about the possible effects of globalization, only recently has there been serious debate on how an increased connectedness among the political, economic and cultural has affected education. In this article, the influenced...

This paper is a report of the impact of an externally funded, multiyear systemic reform project on students’ science achievement on a modified version of the Third International Mathematics and Science Study (TIMSS) test in 33 small, rural school districts in two Midwest states. The systemic reform effort utilized a cascading leadership strategy of professional development delivered at summer w...

The findings of the TIMSS Videotape Classroom Study include aspects of mathematics lessons showing a strong resemblance between Germany and the U.S. in difference to Japan. This paper discusses some of the features that appear to make Japanese lessons different from the other two countries. In particular, the paper examines the goals of lessons described by Japanese teachers, how lessons are st...

Article history: Received 19 November 2012 Received in revised form 18 February 2013 Accepted 29 March 2013 Available online 16 May 2013 Cognitive ability differences between countries can be large, with average IQs ranging from approximately 70 in sub-Saharan Africa to 105 in the countries of north-east Asia. A likely reason for the great magnitude of these differences is the Flynn effect, whi...
