We have conducted action research involving an instructional intervention over a 20-year period. This has demonstrated that spatial ability influences academic performance in engineering, and can be increased through instruction focused on using perception and mental imagery in three-dimensional representation. Prior to our intervention, the first-year engineering graphics course at our university had a failure rate of 36% for all engineering students and failure rates of 80% for African students studying at our university. Similar high failure rates were reported in engineering drawing and design courses at other Southern African universities, and similar association between low scores on tests of spatial ability and academic performance, suggesting that the problem was one encountered by many engineering students, not just by students at our university. Over the initial 2 years of the intervention, pass rates for the first-year engineering graphics course increased from 64 to 76%. With further changes in teaching, and the training of senior students as tutors to support the lecturing and practical activities provided in the course, the pass rates have risen to 88% annually, over a period in which the composition of the first-year student has become increasingly diverse, with greater numbers of students entering the university from disadvantaged educational backgrounds. The instructional model we have used is based on Piagetian principles, and confirms Piaget's theories with respect to the trainability of spatial ability in adulthood. Our findings suggest the importance of early identification of students with difficulty, as well as the potential value of an intervention aimed at training the processes involved in visualization through three-dimensional modelling and representation of objects. While spatial ability appears to be trainable through the methods we have developed, our research also indicates that level of spatial ability at time of intake to university is an important influence on academic performance, suggesting the value of instruction in visualization and three-dimensional representation at school level. Social factors are also important influences on academic performance, suggesting the value of tutorial-based interventions aimed at improving spatial ability in those university and technikon courses for which visualization and three-dimensional representation are a requirement.  相似文献

One can see, in many countries, a rapid increase of the number of girls and women entering engineering education. This recent and optimistic trend must not hide the serious fact that the engineering studies cover the sectors of higher education where women are the more under-represented. Within a report produced for UNESCO (to be published at the end of 1986), and within this paper, the author demonstrates that engineering education is three times less feminized than the average of higher education sectors. The result for engineering is that there is an important misuse of human resources. Women engineers could be crucial to the satisfactory developments of the engineering professions.  相似文献

The present paper is part of a larger study carried out in North Queensland, Australia, between 1999 and 2001. The original study focused on the perceptions of 15 women who each have (or had) a child who was medically, educationally and socio‐culturally constituted as having a disability. Qualitative methods were used for research design and to gather data. Poststructural and feminist perspectives were added to provide additional methods of data analysis. The primary focus in this paper is the spatiality of inclusive education with/in the discursive site of (special) education. It also considers the binary of regular/special education in relation to the spaces of educational discourse through the perspectives of the mothers, covering a temporal frame of 40 years. The mothers’ perceptions provide a historical lens on the changes that occurred in special education in North Queensland over this time, while at the same time offer an insight into the spaces disability occupies in education discourse.  相似文献

According to Alasdair MacIntyre's influential account of practices, ‘teaching itself is not a practice, but a set of skills and habits put to the service of a variety of practices’ ( MacIntyre and Dunne, 2002 , p. 5). Various philosophers of education have responded to and critiqued MacIntyre's position, most notably in a Special Issue of the Journal of Philosophy of Education (Vol. 37.2, 2003). However, both in that Special Issue and since, this debate remains inconclusive. Much of this earlier discussion seems to accept that teaching is a unique case in being a putative practice that does not fit readily into MacIntyre's account. In fact many supposed practices, including some nominated by MacIntyre himself, do not fit his account. A constructive critique of this account leads to a refurbished, broadly MacIntyrean account of practice. This will clarify the issue of whether teaching and a range of other activities are, indeed, practices.  相似文献
