In recent years, there has been a strong push to transform STEM education at K-12 and collegiate levels to help students learn to think like scientists. One aspect of this transformation involves redesigning instruction and curricula around fundamental scientific ideas that serve as conceptual scaffolds students can use to build cohesive knowledge structures. In this study, we investigated how students use mass balance reasoning as a conceptual scaffold to gain a deeper understanding of how matter moves through biological systems. Our aim was to lay the groundwork for a mass balance learning progression in physiology. We drew on a general models framework from biology and a covariational reasoning framework from math education to interpret students' mass balance ideas. We used a constant comparative method to identify students' reasoning patterns from 73 interviews conducted with undergraduate biology students. We helped validate the reasoning patterns identified with >8000 written responses collected from students at multiple institutions. From our analyses, we identified two related progress variables that describe key elements of students' performances: the first describes how students identify and use matter flows in biology phenomena; the second characterizes how students use net rate-of-change to predict how matter accumulates in, or disperses from, a compartment. We also present a case study of how we used our emerging mass balance learning progression to inform instructional practices to support students' mass balance reasoning. Our progress variables describe one way students engage in three dimensional learning by showing how student performances associated with the practice of mathematical thinking reveal their understanding of the core concept of matter flows as governed by the crosscutting concept of matter conservation. Though our work is situated in physiology, it extends previous work in climate change education and is applicable to other scientific fields, such as physics, engineering, and geochemistry. 相似文献

Instructional practices in secondary science: How teachers achieve local and standards-based success

This article reports on analyses of the instructional practices of six middle- and high-school science teachers in the United States who participated in a research-practice partnership that aims to support reform science education goals at scale. All six teachers were well qualified, experienced, and locally successful—respected by students, parents, colleagues, and administrators—but they differed in their success in supporting students' three-dimensional learning. Our goal is to understand how the teachers' instructional practices contributed to their similarities in achieving local success and to differences in enabling students' learning, and to consider the implications of these findings for research-practice partnerships. Data sources included classroom videos supplemented by interviews with teachers and focus students and examples of student work. We also compared students' learning gains by teacher using pre–post assessments that elicited three-dimensional performances. Analyses of classroom videos showed how all six teachers achieved local success—they led effectively managed classrooms, covered the curriculum by teaching almost all unit activities, and assessed students' work in fair and efficient ways. There were important differences, however, in how teachers engaged students in science practices. Teachers in classrooms where students achieved lower learning gains followed a pattern of practice we describe as activity-based teaching, in which students completed investigations and hands-on activities with few opportunities for sensemaking discussions or three-dimensional science performances. Teachers whose students achieved higher learning gains combined the social stability characteristic of local classroom success with more demanding instructional practices associated with scientific sensemaking and cognitive apprenticeship. We conclude with a discussion of implications for research-practice partnerships, highlighting how partnerships need to support all teachers in achieving both local and standards-based success. 相似文献

In this study the origin and evolution of the meanings of the concepts 'amount of substance' and 'mole' are described. Serious disagreements about these concepts amongst chemistry teachers and the recommendations of the international scientific community are identified. Attention is also drawn to the didactic implications that these epistemological difficulties may have for the teaching of chemistry. 相似文献

The New Labour government, in its Green Paper on the Learning Age, published in February 1998, put lifelong learning at the heart of its programme. In this article we aim to demonstrate that there is a direct parallel between the processes outlined in the Green Paper and the processes of experiential learning and community development by focusing on the Diploma in Community and Youth Work Studies run by the Community Work Unit (CWU) based in the Centre for the Development of Continuing Education at the University of Manchester.Community action provides a setting for informal education. Community workers are in a unique position in relation to developing the potential for learning in the groups and individuals with whom they work. Their education and training should enable them to articulate and value their experience and reflect upon it in order to establish a meaningful basis for further self- and/or community development. We will explore how the CWU uses participative learning methods which recognize, value and use the experience and understanding of the participants as a basis for their own and others’ learning, and the relevance of these learning methods to the work practice of the participants. 相似文献

This article reports on a participant‐centred research project with English teachers in a senior secondary college in Melbourne, Australia. It builds on previous research (Weaven and Clark 2009, 2011), which showed a low take‐up of the opportunities to teach poetry in Victoria's senior secondary English curriculum. This study explores the reasons why teachers of English are unwilling to use poetry texts in their senior classes. The teachers who participated in this study discussed and documented their attitudes towards the teaching of poetry and explored with each other the pedagogical challenges associated with teaching poetry. Their discussions – an analysis of which forms the empirical core of this article – reveal a range of explanations for teachers' reservations about offering poetry to their students. Importantly, these teachers were able to use professional discussion as a means to consider what changes in teaching practice could be successfully developed to facilitate more time spent on the teaching of poetry in senior secondary classes. 相似文献

For democracies to thrive, citizens have to be taught to be democrats. How do people learn to be democrats in circumstances of diversity and plurality? We address this question via a discussion of three models of deliberative democracy: public reason (as exemplified by Rawls), discursive democracy (as exemplified by Benhabib) and communicative democracy (as exemplified by Young). Each of the three theorists contributes to an account of how to educate citizens by teaching talk. Against a commonly held assumption that the protection of diversity in a pluralist democracy requires a thin conception of citizenship education, we defend a thick conception that simultaneously fosters autonomy and participation without sacrificing tolerance of diversity. 相似文献

This article, written by Mary Nugent, an educational psychologist working with the National Educational Psychology Service in Dublin, reviews the work done in a special school, in the Dublin area, to develop a Reading Partners Scheme. The school involved in the project, which will be referred to as St Mark's, is a special school for children with moderate learning difficulties (in Ireland described as mild learning difficulties). The Reading Partner's Scheme involved cross-age peer tutoring in reading, working with students in the 8 to 18 age range. The training, organisation and management of the scheme are outlined here. Evaluation studies indicate multiple benefits of the scheme, accruing to both the learners and the helpers. These benefits include progress in reading, enhanced feelings of self-worth and more positive attitudes to school. Ideas for further development of the scheme are described, as well as future research opportunities. 相似文献
