Contrasting the Effectiveness of Fluency Interventions for Students with or At Risk for Learning Disabilities: A Multilevel Random Coefficient Modeling Meta‐Analysis

This study had two purposes. First, we sought to compare the overall effectiveness of different types of fluency interventions for students with learning disabilities (LD). Second, we attempted to identify how individual‐ and class‐level characteristics moderated each intervention's effectiveness. We used multilevel random coefficient modeling to analyze results from 30 single‐subject studies involving 107 students with or at risk for LD. Doing so allowed us to assess the intervention's impact in terms of both intercept‐ (i.e., mean difference between study phases) and slope‐level (i.e., rate of growth) changes. Results indicated that two motivation‐focused interventions were significantly more effective than other types of interventions across gender, age, and placement. The least effective intervention was word recognition training; this finding was consistent across all levels of analyzed variables.     

An Approach to Teaching Electrical Energy

The paper discusses the implementation of a new teaching programme for electrical power engineering graduates. The balance between the different parts of the curriculum (non-technical, technical non-electric, electric non-power and real electrical power) is proposed and explained given the specific context. The logical information flow throughout the education process and the links between the course topics are explained.     

Rare-earth magnets

Magnetism has been known as a natural phenomenon, for over two thousand years and the art of magnetizing steel was mastered half that time ago. However, it is only during this century that really substantial improvements have been made in the energy product of magnets. This article reviews the development of permanent magnets, with special reference to powerful modern alloys containing the rare earths neodymium and samarium.     

The effect of illustrations in arithmetic problem-solving: Effects of increased cognitive load

Arithmetic word problems are often presented accompanied by illustrations. The present study examined how different types of illustrations influence the speed and accuracy of performance of both good (n = 67) and poor arithmeticians (n = 63). Twenty-four arithmetic word problems were presented with four types of illustrations with increasing information value. The results show that illustrations can have a detrimental effect on performance on arithmetic word problems, produced by irrelevant, redundant or interacting sources of information. Principles from cognitive load theory are used to explain the results, in particular in relation to (poor) working memory ability.     

A High-School Science Teacher Views Industry-Education Cooperation

Teachers actively engaged in the classroom do not agree that today's science education is a failure. Schools are expressions of our culture, and their deficiencies have much deeper roots than most current analyses recognize. Fundamental rather than superficial remedies are indicated. Industry, in its approach to education must recognize the central importance of the teacher himself as an expert in the job to be done, and try to adjust its efforts to the special conditions of the classroom. Certain of the steps now being taken by industry in the field of secondary education are noted, and suggestions for their improvement are offered. It is necessary to put intellectual interests in a favorable competitive position with respect to more glamorous teen-age activities, and a possible action in this direction is suggested. Improvement of the economic and social status of the teaching profession would be the single most powerful development in bringing about better secondary education.
