This paper explores the issues and concems identified by a small group of teachers implementing technology ideas using the
national document,A Statement on Technology for Australian Schools (Curriculum Corporation, 1994a), represented in four key questions they posed as a result of reflection upon their existing
ideas and practices, early in the study. These same issues and concerns framed their later experiences as the study progressed.
The case study of one of the teachers is used, to illustrate how the teachers implemented technology education working from
their own perspectives and tackling issues and concerns that made sense to them. By reviewing the teachers' own questions
about technology implementation, it is becoming, clear that what may be important for professional development in technology
education is related to the questions that the teachers themselves are asking about their own, beliefs and practices. 相似文献

The ability to successfully discriminate between multiple potentially relevant source analogs when solving new problems is crucial to proficiency in a mathematics domain. Experimental findings in two different mathematical contexts demonstrate that providing cues to support comparative reasoning during an initial instructional analogy, relative to teaching the same analogs and solution strategies without such cues, led to increased ability to discriminate between relevant analogs at a later test. Specifically, providing comparative gestures and visibly aligned source and target problems during initial learning led to higher rates of positive extension of learning to new contexts, and lower rates of susceptibility to misleading contextual features, both immediately and after a week delay. 相似文献

This paper distils 24 years of classroom research into promoting quality learning in science classrooms to develop an overall
framework for better understanding and describing both the learning and the teaching approaches that stimulate and support
it. For me, quality learning is characterised by adjectives such as informed, purposeful, reflective, intellectually active,
metacognitive and independent. Central to quality learning is the role of talk, and central to promoting talk which promotes
quality learning are certain teacher behaviours. I first focus on the ways that teachers behave in the classroom in order
to promote, react to and use student talk. These behaviours are summed up in a list of twelve principles for quality teaching.
Each of these principles requires, as well as appropriate teacher behaviours, the use of effective teaching procedures. I
then focus on four kinds of student talk that exemplify informed, purposeful, reflective and intellectually active thinking.
These variously involve students’ existing ideas and explanations; increasing student ownership of practical activities; constructive
challenges to the teacher (or text’s) idea, and lateral, reflective ‘thinking’ questions. 相似文献

This paper reports on an in‐depth interview study of the roles, job jurisdictions and associated learning of higher level teaching assistants (HLTAs). This role has the core purpose of covering classes to enable teacher release for planning, preparation and assessment. HLTAs’ individual job jurisdictions are described and discussed as are implications for their knowledge and practice. The HLTAs are found to have wide‐ranging job domains and, sometimes, unexpected involvements which mean they have to improvise practice. The study acknowledges that these HLTAs are being creatively managed and deployed by head teachers for the sake of teachers and schools. However, they are, at times, required to take on planning and cover duties which are beyond their knowledge and training with a likely impact on children’s learning. Given their training and experience it is asked if covering classes to release teachers is the most effective use of their abilities and time. 相似文献

The research set out in this paper attempts to identify whether one of three conventional IQ tests is more capable of identifying intellectual potential amongst poor children in Dar es Salaam. To this end 1857 children from 17 government schools in poor districts of Dar es Salaam were asked to complete a questionnaire and undertake a range of tests. The study included teacher, peer and self-nomination. It has been noted that static testing may not fully elicit the abilities of African children. It has been suggested that dynamic testing might provide a more fair and equitable means of assessment. Therefore 101 students took part in a control and intervention group in order to investigate. The findings show a significant correlation between IQ test scores and other test outcomes. Those with larger families and older children perform less well on IQ tests. Peer ability and self-confidence positively influence test scores. 相似文献
