Conceptions of teaching held by academic teachers

This study examines conceptions of teaching held by academic teachers in the fields of science and social science, in two universities: a distance university in the UK and a traditional one in Australia. A five level classification of conceptions of teaching is proposed. A process of arriving at this scheme is discussed and a formalised coding system is presented which helps to delimit, with greater confidence, the boundaries of each conception, and helps to order conceptions, to compare conceptions proposed by other researchers, and to place individuals within conceptions. The same coding system is then used to define the concepts of student-centered and teacher-centered approaches to teaching. There is a strong suggestion that teaching conceptions are context-dependent.

How Many Variables Can Humans Process

The conceptual complexity of problems was manipulated to probe the limits of human information processing capacity. Participants were asked to interpret graphically displayed statistical interactions. In such problems, all independent variables need to be considered together, so that decomposition into smaller subtasks is constrained, and thus the order of the interaction directly determines conceptual complexity. As the order of the interaction increases, the number of variables increases. Results showed a significant decline in accuracy and speed of solution from three-way to four-way interactions. Furthermore, performance on a five-way interaction was at chance level. These findings suggest that a structure defined on four variables is at the limit of human processing capacity.

Using Journal Writing to Enhance Student Teachers’ Reflectivity During Field Experience Placements

Abstract This paper investigates the use of reflective journals to facilitate student learning during a teacher education practicum. Thirty‐five student teachers undertaking a 1‐year Graduate Diploma of Education submitted weekly journal entries during their 11‐week practicum and were interviewed at several stages about their educational beliefs and practices. Students were randomly assigned to four intervention conditions which varied the content of journalling (experiential or cognitive) and the context (provision of reflective dialogue based on journal entries or self‐analysis). The evidence reported here includes the focus and level of students’ reflections, the effects of the intervention conditions, and students’ perceptions of the value of journalling. Although there was some evidence that students found it easier to write an experiential than a cognitive journal, there were no overall differences in the quality of reflection achieved under the two conditions. Students receiving supervised dialogue...

How academics use technology in teaching and learning: understanding the relationship between beliefs and practice

This paper reports on a detailed investigation into the beliefs and practices of teachers in 22 computer-assisted learning projects in Australia in the mid-1990s. Detailed interview data were obtained, supported by the project software and other curriculum materials. The interview transcripts and documentary material were collated and condensed into rich descriptions; these were then coded on a number of belief and practice dimensions. The resulting profiles were clustered into five belief‐practice categories: thoughtful instructors, pre-emptive professionals, conversational constructivists, learning facilitators and situated knowledge negotiators. These complex, yet interpretable, patterns of relationships between beliefs and practices are useful in understanding teachers’ reluctance to change their teaching, one instance of which is the relatively limited uptake of technology in higher education.

Describing Computer-Facilitated Learning Environments in Higher Education.

The research reported here is part of a study of the ways in which university academics design and incorporate computer-facilitated learning (CFL) environments into their courses. This study was based on archive material only (the initial application and final report) for 36 externally-funded technology-based projects from a number of disciplines. Projects were sorted into categories based on educational assumptions and practices. Categories were then compared and refined so as to reveal their major sources of similarity and difference. The resulting framework is one in which the use of educational technology in higher education can be interpreted in terms of several key qualitative dimensions which reflect academics’ beliefs about the origin of knowledge, the learning framework, control of the direction of learning, and the nature of the knowledge and of the learning process.

Assessment of attention relationship between psychological testing and information processing approaches

Examined the relationship between the psychological testing and information processing approaches in assessing attention. Eighty-seven subjects (57 females, 30 males) undertook eight psychological tests of attention and a visual-spatial reaction-time task. Using the cognitive-correlate method (Posner & McLeod, 1982), it was found that three components of attention (viz., visual-motor scanning, sustained selective processing, and visual/auditory spanning) derived from the psychological tests could be significantly predicted by specific, yet different, combinations of six indices of information processing (mean reaction time (RT), mean movement time (MT), feature extraction, identification, response selection, and motor adjustment): (a) mean RT and mean MT were found to be the most important indices for predicting performance on visual-motor scanning; (b) the motor-adjustment stage was found to be the most important index for predicting performance on sustained selective processing; (c) the response-selection stage was found to be the most important index for predicting performance on visual/auditory spanning. These relationships are important for supporting the construct-related validity of the psychological tests of attention and for extending the generality and applicability of the RT task.
