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…

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…
