Abstract Gaining knowledge of what contextual factors may contribute to changes in student achievement across cycles international large-scale assessments (ILSA), is important for educational policy and practice. Addressing this necessitates advanced methodology that utilizes the trend design ILSAs. The Trends International Mathematics Science Study (TIMSS) data suitable such analyses as it mea...

Background: In 2011 the Progress in International Reading Literacy Study (PIRLS) and the Trends in International Mathematics and Science Study (TIMSS) were conducted at fourth grade in a number of participating countries with a shared representative sample. In this article we investigate whether there are multidimensional proficiency patterns across the competency domains or not. Methods: In or...

Educational assessment is a process of collecting evidence and interpreting it to provide instructors with information regarding students’ learning. However, the current design and scoring of most standardized educational tests are insufficient to serve this purpose. The limitation exists primarily due to the lack of cognitive information incorporated into traditional psychometric models. To da...

يهدف البحث إلى تقصي فاعلية برنامج تدريبي مقترح قائم على متطلبات التوجهات الدولية لدراسة العلوم والرياضيات TIMSS في تنمية المهارات التدريسية لدى معلمات للمرحلة المتوسطة والتحصيل الدراسي لطالباتهن. وقياس فاعليته (29) معلمة من المتوسطة، وزعن عشوائيًّا مجموعتين: الأولى تجريبية، عدد أفرادها (14) معلمة، تدربن البرنامج التدريبي المقترح، والأخرى ضابطة، (15) لم يتم تدريبهن. أثر ذلك التحصيل (300) طالبة طال...

This study examines the generalizability of a previously validated model on how student perceptions of the school culture affects student achievement. Third International Mathematics and Science Study (TIMSS) data were collected from 1026 eighth-grade students in secondary schools in Cyprus. The results indicated that achievement scores can be explained by student perceptions of the school cult...

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 ...
