In "A Framework for K-12 Science Education," researchers call for teachers to make dramatic shifts in practice -- and sustain in these changes in practice -- so students can engage in rigorous and equitable three-dimensional science learning. Project-Based Learning (PBL) motivates students from diverse backgrounds to persist in learning.…

It has been determined that the drawings, photographs and pictures related to the subject of the continuity of the tangent function on page 68 of the Ministry of National Education's twelfth-grade mathematics textbook contradict principles 1, 7 and 10 of Yanpar's (2007) teaching material development principles. According to these principles,…

Literature suggests using multimedia learning principles in the design of instructional material. However, these principles may not be sufficient for the design of learning objects for concept learning in mathematics. This paper reports on an experimental study that investigated the effects of an instructional approach, which includes two teaching…

The best method for determining the size of learning objects (LOs) so as to optimise their reusability has been a topic of debate for years now. Although there appears to be agreement on basic assumptions, developed guidelines and principles are often in conflict. This study shows that this confusion stems from the fact that in the literature,…

This study is a report on the design, development, and validation of a model within the main tenets of critical pedagogy (CP) with a hope to implement in education in general and applied linguistics in particular. To develop a transformative L2 materials preparation (TLMP) model, the researchers drew on Crawford's (1978) principles of CP as a…
