Self-regulated learning: Implications for the design of instructional media   总被引:1,自引:0,他引:1  
This paper describes the implications of principles derived from cognitive social learning theory and Vygotsky's socially oriented developmental perspective for the design of technology-based instructional materials. Vygotsky's ideas about the kinds of experience that facilitate intellectual growth in the “zone of proximal development” suggest that contemporary mathematics instruction (usually characterized by presentations to large groups, or by individualized instruction dominated by worksheets) deny students opportunities for individual interaction with and supportive guidance by adult experts or competent peers. It is proposed that such instruction fails to support the transfer of regulatory responsibility from teacher to student. The derivation of design specifications for the use of instructional technologies to overcome these limitations of contemporary instruction in mathematics is described. Instructional materials designed to promote self-regulation strategies as well as procedural and declarative knowledge in mathematics are presented.  相似文献

We report on how two middle-grade teachers supported their students’ mathematical reasoning within the context of a novel modeling task in data analysis. We examine how the task features supported the development of teachers’ knowledge as their students engaged with the task. Analyses of the teachers’ practices suggest that the task features enabled teachers: (a) to develop new understandings of the mathematical content and the ways in which student ideas develop and are represented; (b) to adopt new roles in their interactions with the students, including a focus on listening and observing, and on asking questions for understanding and clarification; and (c) to engage in forms of interpretative listening that shifted the role of evaluation from the teacher to the student. This material is based upon work supported by the National Science Foundation (NSF) under Grant No. 9722235 and by the Australian Research Council (ARC).  相似文献

Abstract

This paper considers whether subject choice at 14–16 influences post-16 transitions, taking into account prior academic attainment and school characteristics, and if so, whether this accounts for socioeconomic, gender, and ethnic differences in access to post-16 education. We consider post-16 progression to full-time education, A-levels, and studying two or more facilitating subjects at A-level. We use ‘Next Steps’, a study of 16,000 people born in England in 1989–1990, linked to administrative education records (the National Pupil Database). We find that students pursuing an EBacc-eligible curriculum at 14–16 had a greater probability of progression to all post-16 educational outcomes, while the reverse was true for students taking an applied GCSE subject. Curriculum differences did not explain the social class differences in post-16 progression, but an academic curriculum was equally valuable for working-class as for middle-class pupils. Pursuing an EBacc-eligible curriculum particularly strongly increased the chances of girls and white young people staying in the educational pipeline, whereas applied subjects were particularly detrimental for girls. An EBacc-eligible curriculum at age 14–16 increased the chances of studying subjects preferred by Russell Group universities at A-level.  相似文献

Student evaluations of teaching (SETs) have been used to evaluate higher education teaching performance for decades. Reporting SET results often involves the extraction of an average for some set of course metrics, which facilitates the comparison of teaching teams across different organisational units. Here, we draw attention to ongoing problems with the naive application of this approach. Firstly, a specific average value may arise from data that demonstrates very different patterns of student satisfaction. Furthermore, the use of distance measures (e.g. an average) for ordinal data can be contested, and finally, issues of multiplicity increasingly plague approaches using hypothesis testing. It is time to advance the methodology of the field. We demonstrate how multinomial distributions and hierarchical Bayesian methods can be used to contextualise the SET scores of a course to different organisational units and student cohorts, and then show how this approach can be used to extract sensible information about how a distribution is changing.  相似文献

The paper reports on key findings of a research project that examined the roles that community-based sporting clubs in the Australian state of Victoria play in shaping young people's understandings and uses of alcohol. Our research imagined clubs as community hubs that are located in complex networks that impact on the ways that clubs understand their locations in communities, and which have unpredictable influences and consequences on club histories, culture and orientations to issues such as young people and alcohol use. The paper focuses on understanding the key roles played by club leaders in facilitating change and transformation in these contexts, particularly in terms of alcohol-related practices and the potential impact of these on young people's uses and understanding of alcohol. We situate these findings in a framework that draws on the literature of complexity science and complex adaptive systems (CAS) to suggest that these practices and changes need to be understood in ways that allow for complexity, uncertainty, emergent behaviours and adaptive change.  相似文献

The Development of Fifth-Grade Children's Problem-Posing Abilities   总被引:3,自引:0,他引:3  
This one-year study involved designing and implementing a problem-posing program for fifth-grade children. A framework developed for the study encompassed three main components: (a) children's recognition and utilisation of problem structures, (b) their perceptions of, and preferences for, different problem types, and (c) their development of diverse mathematical thinking. One of the aims of the study was to investigate the extent to which children's number sense and novel problem-solving skills govern their problem-posing abilities in routine and nonroutine situations. To this end, children who displayed different patterns of achievement in these two domains were selected to participate in the 10-week activity program. Problem-posing interviews with each child were conducted prior to, and after the program, with the progress of individual children tracked during the course of the program. Overall, the children who participated in the program appeared to show substantial developments in each of the program components, in contrast to those who did not participate.  相似文献
