The Structure of Ill-Structured (and Well-Structured) Problems Revisited

Educational Psychology Review - In his 1973 article The Structure of ill structured problems, Herbert Simon proposed that solving ill-structured problems could be modeled within the same...     

‘Operating on a Basis of Student Consent’: Peter Medway’s Work in Finding a Language

Written nearly 40 years ago, Peter Medway’s Finding a Language continues to be an arresting read, which offers a powerful vision of what might be possible in education. In this brief introduction, I set the work in context, referring to ideas that Pete engaged with and recalling a little of the times.     

Integrated Reading and Writing Interventions for Students with Learning Disabilities: A Review of the Literature

In this systematic review of literature that spans 1975–2015, integrated reading and writing interventions for students with learning disabilities (LD) or students with academic difficulties were evaluated to understand the extant research, identify encouraging practices, and guide future research. Ten studies met inclusion criteria and each study was evaluated according to the relevant What Works Clearinghouse (WWC) design standards. Eight of the 10 investigations were conducted with students in grades 4–8. While only 4 of the 10 studies met WWC design with or without reservations, results from these studies are encouraging. Study findings suggest several areas for immediate future research relating to methodological and treatment variables and considerations for classroom instruction in order to respond to advanced expectations for the successful integration of reading and writing across subjects. In addition to employing stronger experimental designs and additional replications of encouraging studies, future research should explore the utility of integrated reading and writing interventions with secondary students with who have academic difficulties.     

Phasing science InSET in developing countries: reflections on the experience of the Primary Science Programme in South Africa

In many developing countries attempts to develop the quality of science education stress the importance of inservice education and training (InSET). This article focuses on how such InSET should be phased through time for maximum effect. Several theoretical models that describe and explain stages in the processes of professional learning or educational development are reviewed. Their relevance in informing the planning of science InSET is reviewed in the light of the experience of the Primary Science Programme (PSP) in South Africa. Two main criticisms of existing models are made: 1. They neglect language development as a crucial factor limiting the development of teaching styles especially where pupils are learning in a second language. 2. There are flaws in the way that the recommendations of models have been combined in existing synthesis models. Finally a synthesis model for the phasing of science InSET is proposed.     

Examining the “Blanket of Protection” Conferred by Inoculation: The Effects of Inoculation Messages on the Cross-protection of Related Attitudes

Although the effectiveness of inoculation as a strategy for promoting resistance to attitude change is fairly well established, the potential of inoculation messages to offer cross-protection for related, but untreated, attitudes warrants additional attention from scholars. The reported study tested the “blanket of protection” conferred by inoculation. Participants (N = 118) were randomly assigned to read an inoculation message addressing a target topic and subsequently had their attitudes toward three related, but untreated, topics attacked. The results offer some evidence that inoculation messages can confer cross-protection for related attitudes. Participants in the inoculation condition reported greater perceptions of threat, greater counterarguing, and less attitude change in response to attacks than participants in the control condition for two of the three untreated topics. Counterarguing in response to attacks on untreated attitudes appears to be primarily responsible for cross-protection.     

The effect of 14 weeks of vitamin D3 supplementation on antimicrobial peptides and proteins in athletes

Heavy training is associated with increased respiratory infection risk and antimicrobial proteins are important in defence against oral and respiratory tract infections. We examined the effect of 14 weeks of vitamin D₃ supplementation (5000 IU/day) on the resting plasma cathelicidin concentration and the salivary secretion rates of secretory immunoglobulin A (SIgA), cathelicidin, lactoferrin and lysozyme in athletes during a winter training period. Blood and saliva were obtained at the start of the study from 39 healthy men who were randomly allocated to vitamin D₃ supplement or placebo. Blood samples were also collected at the end of the study; saliva samples were collected after 7 and 14 weeks. Plasma total 25(OH)D concentration increased by 130% in the vitamin D₃ group and decreased by 43% in the placebo group (both P = 0.001). The percentage change of plasma cathelicidin concentration in the vitamin D₃ group was higher than in the placebo group (P = 0.025). Only in the vitamin D₃ group, the saliva SIgA and cathelicidin secretion rates increased over time (both P = 0.03). A daily 5000 IU vitamin D₃ supplement has a beneficial effect in up-regulating the expression of SIgA and cathelicidin in athletes during a winter training period, which could improve resistance to respiratory infections.
