The current meta-analysis quantifies the average effect of worked examples on mathematics performance from elementary grades to postsecondary settings and to assess what moderates this effect. Though thousands of worked examples studies have been conducted to date, a corresponding meta-analysis has yet to be published. Exclusionary coding was…

Building the communicative competence of individuals who use augmentative and alternative communication (AAC) requires intervention and support. This systematic review examined experimental studies involving aided AAC modeling to promote the expressive communication of children and youth (i.e., birth to age 21) with complex communication needs. A…

Instructor modeling is a practice that is supported by bold claims of effectiveness and importance in teacher education. In this literature review, we identify theoretical and constructive frameworks used to guide instructor modeling and use these to further examine the extent to which existing literature demonstrates the effectiveness of…

Simulation-based learning offers a wide range of opportunities to practice complex skills in higher education and to implement different types of scaffolding to facilitate effective learning. This meta-analysis includes 145 empirical studies and investigates the effectiveness of different scaffolding types and technology in simulation-based…

The role of teacher aides (TAs)1 has increased in complexity and includes working to support students with challenging behaviour. This review examines the professional learning and development (PLD) needs of TAs who work with students with challenging behaviour and the types of PLD which are effective. TAs feel underprepared for behaviour work and…

Evidence of confusion in intermediate accounting textbooks regarding the annual percentage rate (APR) and annual effective rate (AER) is presented. The APR and AER are briefly discussed in the context of a note payable and correct formulas for computing each is provided. Representative examples of the types of confusion that we found is presented…

Many approaches to make mathematics relevant to first-year engineering students have been described. These include teaching practical engineering applications, or a close collaboration between engineering and mathematics teaching staff on unit design and teaching. In this paper, we report on a novel approach where we gave higher year engineering…

Developing and updating subject knowledge is an important and ongoing area of professional development. As well as formal subject-specific CPD, teachers can extend their pedagogical subject knowledge by researching and using curriculum materials. This article reviews the resources available from the National STEM Centre eLibrary to help teachers…

This essay offers an analysis of PowerPoint apart from the histrionics of the "'Tis and 'Taint" arguments about its value, and proposes a program of research to move forward our understanding of PowerPoint as an inscriptional system. To that end, the study begins with a discussion of PowerPoint as an inscriptional system that employs both…

The discussion of the gap between theory and practice has a long tradition in educational psychology and especially in research on learning and instruction. Starting with a short analysis of more or less elaborated approaches focusing on this problem, a complex procedure called "integrative research approach", specialized in reducing the gap…

Examines Madeline Hunter's "model" of teaching and compares it to other models. The model involves a sequential arrangement of seven steps: (1) anticipatory set; (2) objective and purpose; (3) input; (4) modeling; (5) checking for understanding; (6) guided practice; and (7) independent practice. Provides reason for and examples of each…

Reports on the comparative effectiveness of demonstration and lecture formats for presenting physiological measures. Although demonstrations may improve retention of information concerning simple procedures, the lecture format is more effective for complex information. (CFR)

This article reviews five modes of computer-assisted software so that teachers will be more aware of them and use computers more in their classrooms. The five modes are the following: (1) drill and practice; (2) tutorial; (3) simulation; (4) demonstration; and (5) instructional games. Teachers should review softwares and choose those that meet…

Studies in Science Education is an international review of research for all who are interested in the educational dimensions of science. This issue contains these articles: "Teaching about Science, Technology and Society at the Secondary School Level in the United States. An Educational Dilemma for the 1980s" (Mary C. McConnell); Science…

Describes the phenomenological and microscopic aspects of solid-state diffusion in an electric field and presents a Monte Carlo method which is used to stimulate an atomistic model of diffusion in an electric field. The Nernst-Einstein relation is also discussed. (HM)
