Breadth and depth of curriculum are important for success in science teaching and learning. Curriculum theorists recommend less breadth and more depth than overloaded, superficial science curricula. This study investigates breadth and depth in the official biology syllabi in the seventh to eighth or ninth years in four diverse jurisdictions,…

Background: Integrated science is a ubiquitous school subject that is an amalgamation of science disciplines; its teaching allows topics to be sequenced in any order and given various degrees of coverage and emphasis in the classroom. Ensuring canonical coherence, which is the logical organization of subject matter for effective instruction is…

This study aimed at identifying the reasons responsible for the low performance of the students of the second intermediate grade in science's tests in the Trends in International Mathematics and Science Study (TIMSS). It also intends to provide a proposal for developing the performance of the students of the second intermediate grade in science…

This brief utilizes data from the U.S. Trends in International Mathematics and Science Study of 2011 (TIMSS) to investigate the extent to which teacher reports of content coverage in eighth grade algebra classes vary according to school racial/ethnic composition. The analytic sample is comprised of eighth grade algebra classrooms in 111 schools…

Many studies investigating inquiry learning in science domains have appeared over the years. Throughout this period, inquiry learning has been regularly criticized by scholars who favor direct instruction over inquiry learning. In this vein, Zhang, Kirschner, Cobern, and Sweller (2022) recently asserted that direct instruction is overall superior…

This study statistically investigates the characteristics of the intended curriculum for Japanese primary science, focusing on the learning content. The study used the TIMSS 2011 Grade 4 Curriculum Questionnaire data as a major source for the learning content prescribed at the national level. Confirmatory factor analysis was used to determine the…

The results of Romanian students at international comparative TIMSS and PISA tests have constantly proven to be unsatisfactory. The present paper aims at analyzing the school syllabi "Mathematics and Environment exploration", "Environmental Education" and "Natural Sciences" studied during primary education in Romania…

In the study reported here, the authors examined the LEs (learning expectations) related to Grades 1 to 8 number and quantity in mathematics across several US states and high performing TIMSS (Third International Mathematics and Science Study) Asian countries, including Singapore, Taiwan and Japan. The general strategy used is based on the topic…

This article examines the teacher preparation program learning opportunities afforded future lower secondary mathematics teachers and future elementary teachers who may teach mathematics. Data from U.S. participation in the recent international Teacher Education and Development Study in Mathematics are explored against international profiles to…
