The Luddite Revolt continues

The bicentenary in 2011 of the Luddite Revolt prompts us to ask ‘what would Ned Ludd think of today’s automated styles of distance education?’ He would no doubt echo the common criticism that educational technologies create an impersonal style of teaching and learning, and devalue the teacher. He would probably agree that online methods have major potential for millions of distance‐based students who cannot attend classroom‐based education and training; but he would emphasise the need for quality assurance and cost‐effectiveness studies in distance education implementation. He might also ask why anyone would encourage the development of e‐learning in countries where the Internet is largely inaccessible. This article uses the Luddites’ views of workplace automation to explore how global distance education practices might be improved. It suggests that the intentions of the original Luddites were laudable and worthy of application in distance education today.     

Improving seventh grade students’ learning of ratio and proportion: The role of schema-based instruction

The present study evaluated the effectiveness of an instructional intervention (schema-based instruction, SBI) that was designed to meet the diverse needs of middle school students by addressing the research literatures from both special education and mathematics education. Specifically, SBI emphasizes the role of the mathematical structure of problems and also provides students with a heuristic to aid and self-monitor problem solving. Further, SBI addresses well-articulated problem solving strategies and supports flexible use of the strategies based on the problem situation. One hundred forty eight seventh-grade students and their teachers participated in a 10-day intervention on learning to solve ratio and proportion word problems, with classrooms randomly assigned to SBI or a control condition. Results suggested that students in SBI treatment classes outperformed students in control classes on a problem solving measure, both at posttest and on a delayed posttest administered 4 months later. However, the two groups’ performance was comparable on a state standardized mathematics achievement test.     

Educating an iPod generation: undergraduate attitudes,experiences and understanding of vodcast and podcast use

There is an increasing pressure on university staff to provide ever more information and resources to students. This study investigated student opinions on (audio) podcasts and (video) vodcasts and how well they met requirements and aided learning processes. Two experiments within the Aston University looked at student opinion on, and usage of, podcasts and vodcasts for a selection of their psychology lectures. Recordings were produced first using a hand‐held camcorder, and then using the in‐house media department. WebCT was used to distribute the podcasts and vodcasts, attitude questionnaires were then circulated at two time points. Overall students indicated that podcasts and vodcasts were a beneficial addition resource for learning, particularly when used in conjunction with lecturers’ slides and as a tool for revision/assessment. The online material translated into students having increased understanding of the material, which supplemented and enhanced their learning without being a substitute for traditional lectures. There is scope for the provision of portable media files to become standard practice within higher education; integrating distance and online learning with traditional approaches to improve teaching and learning.

Preparation of microcapsules with possible pharmaceutical use

The use of products in microcapsule form has grown in recent years and is now general throughout industry. The techniques of preparation have led to the production of a great variety of types, and material now designed as microcapsular would, only a few years ago, have gone under another name. This article deals almost exclusively with those of pharmaceutical significance.
