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...

هدف: بر اساس مطالعه، بسیاری از دانشجویان، سال اول دانشگاه را یکی دوره‌های زمانی پراسترس و چالش‌زای زندگی می‌دانند قادر به سازگاری مناسب با آن نیستند. مطالعه حاضر هدف شناسایی تجارب زیسته دانشجویان پایین در خصوص مشکلات چالش‌های انجام شد. روش: روش پژوهش کیفی نوع پدیدارشناسی بود. داده‌ها استفاده مصاحبه نیمه ساختاریافته جمع‌آوری شد رویکرد 7 مرحله‌ای کلایزی مورد تجزیه تحلیل قرار گرفت. جامعه کلیه آزاد...

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...

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 ...

Increasing income inequality particularly since the economic crisis of 1997 has called attention to the issue of growing educational inequality in South Korea. Although much recent research has been directed at understanding the socioeconomic gap in academic achievement, few studies have empirically examined how this gap has changed over time during the past decade in South Korea. Using nationa...

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...
