This paper presents and discusses examples of works of art which, if included in science curricula, could prompt an understanding
by students of some concepts in optics through a discussion of the context in which they were created. Such discussion would
elucidate the meaning of the artworks and, at the same time, challenge students’ misconceptions, attracting their attention
to the scientific aspects of the art works concerned. This type of learning represents a culturally rich approach to modern
science curricula. The simplified contrasting of science and humanities is criticized. 相似文献

This paper addresses an issue of increasing significance in the context of taught educational doctorates and argues that this may have wider applicability for doctoral students across a range of social science disciplines. It identifies the need to engage with policy analysis as a key element of such programmes and attempts to address students' concerns over a lack of practical approaches to do so by offering an analytical framework drawing on critical discourse analysis. This paper highlights the affordances of a taught doctorate context to consider the potential for more collaborative community approaches to doctoral pedagogies through reflecting upon the way the frame was introduced and used by one group of EdD students. In doing so, this paper offers both a practical analytical tool for doctoral students but also a pedagogical approach grounded in an invitation to dialogue and induction into the academic discourse community, through a notion of critical inclusion. 相似文献

The phenomenographic ‘approach to learning’ literature holds that students’ approaches to learning can change depending on the learning context. This implies that, by modifying the learning context, teachers can change the way students approach learning, and this can ultimately lead to a change in learning outcomes. The study presented here examines one effort to modify a science, technology, engineering, and mathematics (STEM) learning context and the approaches to learning taken by students experiencing this environment. Using a qualitative, phenomenographic approach, we interviewed 45 students in a STEM peer‐led workshop programme at a large US research university. Similar to previous approach‐to‐learning research, the study identified three approaches students took to learning in the peer‐led programme, in which they focused on simply making it through the course, engaging more meaningfully with the material, and gaining better control over their own learning. 相似文献

Energy is a central topic in physics and a key concept for understanding the physical, biological and technological worlds. It is a complex topic with multiple connections with different areas of science and with social, environmental and philosophical issues. In this paper we discuss some aspects of the teaching and learning of the energy concept, and report results of research on this issue. To immerse science teaching into the context of scientific culture and of the students’ cultural world, we propose to select specific driving issues that promote motivation for the construction of science concepts and models. We describe the design and evaluation of a teaching learning path developed around the issue of greenhouse effect and global warming. The experimentation with high school students has shown that the approach based on driving issues promotes students’ engagement toward a deeper understanding of the topic and favours further insight. The evolution of students’ answers indicates a progressively more correct and appropriate use of the concepts of heat, radiation, temperature, internal energy, a distinction between thermal equilibrium and stationary non equilibrium conditions, and a better understanding of greenhouse effect. Based on the results of the experimentation and in collaboration with the teachers involved, new materials for the students have been prepared and a new cycle of implementation, evaluation and refinement has been activated with a larger group of teachers and students. This type of systematic and long term collaboration with teachers can help to fill the gap between the science education research and the actual school practice. 相似文献

This article discusses the role of context problems, as they are used in the Dutch approach that is known as realistic mathematics
education (RME). In RME, context problems are intended for supporting a reinvention process that enables students to come
to grips with formal mathematics. This approach is primarily described from an instructional-design perspective. The instructional
designer tries to construe a route by which the conventional mathematics can be reinvented. Such a reinvention route will
be paved with context problems that offer the students opportunities for progressive mathematizing. Context problems are defined
as problems of which the problem situation is experientially real to the student. An RME design for a calculus course is taken
as an example, to illustrate that the theory based on the design heuristic using context problems and modeling, which was
developed for primary school mathematics, also fits an advanced topic such as calculus. Special attention is given to the
RME heuristic that refer to the role models can play in a shift from a model of situated activity to a model for mathematical
reasoning. In light of this model-of/model-for shift, it is argued that discrete functions and their graphs play a key role
as an intermediary between the context problems that have to be solved and the formal calculus that is developed.

Instructional strategies and curriculum sequences aimed at teaching process skills have received considerable attention in science education. On the other hand, the teaching of domain-independent, context-free skills has been subject to criticism on the ground that important aspects of cognitive activities are functions of meaningful contexts. The intent of this study was to examine the development of integrated process skills in the context of open-inquiry laboratory sessions. The data-collection approach was qualitative and included videotapes of laboratory sessions, laboratory reports of students, and the reflective journals kept by the two teachers involved in the study. Forty-eight students from the Grade 11 introductory physics course, 29 students from the Grade 12 physics course, and 60 students from the Grade 8 general science course from an all-boys private school participated in the study. An interpretive research methodology was adopted for construction of meaning from the data. Students worked in collaborative groups during all of the open-inquiry laboratory sessions. Findings from the study indicate that students develop higher-order process skills through nontraditional laboratory experiences that provided the students with freedom to perform experiments of personal relevance in authentic contexts. Students learned to (a) identify and define pertinent variables, (b) interpret, transform, and analyze data, (c) plan and design an experiment, and (d) formulate hypotheses. Findings of this study suggest that process skills need not be taught separately. Integrated process skills develop gradually and reach a high level of sophistication when experiments are performed in meaningful context. 相似文献

Context-based chemistry education aims to improve student interest and motivation in chemistry by connecting canonical chemistry concepts with real-world contexts. Implementation of context-based chemistry programmes began 20 years ago in an attempt to make the learning of chemistry meaningful for students. This paper reviews such programmes through empirical studies on six international courses, ChemCom (USA), Salters (UK), Industrial Science (Israel), Chemie im Kontext (Germany), Chemistry in Practice (The Netherlands) and PLON (The Netherlands). These studies are categorised through emergent characteristics of: relevance, interest/attitudes/motivation and deeper understanding. These characteristics can be found to an extent in a number of other curricular initiatives, such as science-technology-society approaches and problem-based learning or project-based science, the latter of which often incorporates an inquiry-based approach to science education. These initiatives in science education are also considered with a focus on the characteristics of these approaches that are emphasised in context-based education. While such curricular studies provide a starting point for discussing context-based approaches in chemistry, to advance our understanding of how students connect canonical science concepts with the real-world context, a new theoretical framework is required. A dialectical sociocultural framework originating in the work of Vygotsky is used as a referent for analysing the complex human interactions that occur in context-based classrooms, providing teachers with recent information about the pedagogical structures and resources that afford students the agency to learn. 相似文献

Modelling is an inherent process for the construction and use of science concepts that mobilize diverse specific competences. The aims of this work are to put forward a means of evaluating modelling competences that is relevant for physics teaching and science education research and to identify the potentials and constraints in the development of modelling competences. A written test, which embraces a wide range of modelling aspects in mechanics domain, was drawn up and validated, and a theoretically based evaluation methodology was specified. In the validation process, the test was given to 75 subjects distributed across seven levels of physics education. The answers were analysed and later cluster analysis was carried out in order to identify categories of answers among the diverse answers. The results indicate that the test identified and delimitated modelling competences. Some results are in agreement with those obtained through other research into this issue and other results better elucidate certain aspects of modelling. The way in which evaluation methodology can be used in other areas of physics is discussed, such as in research and in teaching. Also discussed is how the constraints and potentials identified in the development of modelling competences can be taken into account in teaching and learning sciences. 相似文献

Recently, researchers have demonstrated the benefits of technology-enhanced science inquiry activities. To improve students’ self-regulation and assist them in controlling their own learning pace through inquiry activities, in this study, a self-regulated science inquiry approach was developed to assist them in organizing information from their real-world exploration. A quasi-experimental design was conducted in an elementary school natural science course to evaluate the students’ performance using the proposed learning approach. One class assigned as the treatment group learned with the self-regulated science inquiry approach, while the other class assigned as the control group learned with the conventional science inquiry approach. The students’ learning achievement, tendency of information help seeking, tendency of self-regulation, and self-efficacy were evaluated. The results of the study revealed that the self-regulated science inquiry approach improved the students’ learning achievement, especially for those students with higher self-regulation. In addition, the students who conducted inquiry with the self-regulated learning strategy increased their tendency of information help seeking, self-efficacy, and several aspects of self-regulation, including time management, help seeking, and self-evaluation. Accordingly, this study demonstrated the effectiveness of the self-regulated learning strategy, an approach with high learner control, in terms of improving students’ learning achievement and their self-regulation. 相似文献

The University of Rochester's Graduate Experience in Science Education (GESE) course familiarizes biomedical science graduate students interested in pursuing academic career tracks with a fundamental understanding of some of the theory, principles, and concepts of science education. This one-semester elective course provides graduate students with practical teaching and communication skills to help them better relate science content to, and increase their confidence in, their own teaching abilities. The 2-h weekly sessions include an introduction to cognitive hierarchies, learning styles, and multiple intelligences; modeling and coaching some practical aspects of science education pedagogy; lesson-planning skills; an introduction to instructional methods such as case studies and problem-based learning; and use of computer-based instructional technologies. It is hoped that the early development of knowledge and skills about teaching and learning will encourage graduate students to continue their growth as educators throughout their careers. This article summarizes the GESE course and presents evidence on the effectiveness of this course in providing graduate students with information about teaching and learning that they will use throughout their careers. 相似文献

ABSTRACTThe aim of this study is to provide an understanding of context-based inquiry teaching within a humanistic perspective on science education by studying pre-service teachers’ beliefs about inquiry and their implementations of inquiry in their context-based teaching sequences. Therefore, five pre-service teachers enrolled in a university undergraduate course called ‘Inquiry-based chemistry education II’ (5 ECTS) were involved in an empirical case study. The pre-service teachers’ implementations of inquiry were studied from their reports on self-designed context-based inquiry teaching sequences for students age 13–15, and their beliefs by interviewing them after the course. The results indicate that the most frequent aspects of inquiry, which were implemented, were that inquiry (i) includes a context, (ii) is a way to act, (iii) is a way to think, and (iv) includes source/information evaluation and argumentation. The pre-service teachers’ beliefs about inquiry were shown to reflect manifold aspects of inquiry, such as the difficulty in explaining it. However, this difficulty in encapsulating inquiry into a clear-cut definition is not necessarily an impediment to inquiry-based teaching. Furthermore, inquiry is inherently context-bound, and context-based teaching requires extra-situational knowledge from the context and not only declarative knowledge from science. This should be considered to support effective professional development. 相似文献

An appropriate understanding of the nature of the scientific enterprise (NOSE) is a key element of scientific literacy and can arguably be influenced through an exploration of the history of science. An elective, undergraduate History of Science course was organized in the form of small-group discussion-based inquiries into the history of science from ancient to modern times. Group discussions focused on STATEMENTS OF CRITICAL SIGNIFICANCE (SOCS) prepared by individual students on assigned readings prior to each class meeting. Small-group discussions were followed by a synthesis, facilitated by the instructor, of points raised in SOCS and other ideas central to the reading. The overarching goal of these activities was to help students see the multifaceted nature of the scientific enterprise in the context of social, political, cultural, and religious milieu of the time period and the geographic setting within which specific scientific activities and developments took place. The impact of this course on student understanding of the NOSE was assessed through the use of VIEWS ON SCIENCE-TECHNOLOGY-SOCIETY (VOSTS) instrument administered as pre- and post-test. Qualitative data regarding student understanding of the NOSE were furnished by the final exam on the NOSE written in the form of SOCS at the end of semester. Results based on four semesters of the course offering indicate modest gains in student understanding of specific aspects of the NOSE. They are discussed, along with the usefulness of small-group, discussion-based inquiries into the history of science as a way of enhancing scientific literacy during undergraduate science education. 相似文献

Good teaching should be inclusive of all students. There are very strong arguments for making courses/units/modules as inclusive as possible, based on issues of equity and access. Inclusive teaching has been a catch cry in recent times and most universities have policies related to this issue. However, research into the effectiveness of measures taken to ensure that teaching caters to all students is rare. The scarcity of such information may be due to the difficulty in finding an appropriate method of evaluation. One of the means to evaluate teaching of a unit or course is to obtain feedback from students. Although information collected through this method may be subjected to biases, student perceptions can still provide useful data that can be incorporated into a broader evaluation system. This paper discusses an investigation into the inclusive nature of a large number of units offered at The University of Western Australia over 3 years. Student ratings in relation to the issue of inclusivity were also explored for possible influences of the year level of courses, broad discipline areas and student gender. The results of this study indicate that these three factors could affect how students view the inclusive nature of particular units. 相似文献

Science education reformers have argued that presenting science in the abstract is neither motivating nor inclusive of the majority of students. Science–technology–society (STS) curricula that give science an accessible social context have developed in response, but controversy surrounds the extent to which students should be introduced to socioscientific debate. Using material from a case study of Salters' Advanced Chemistry in the United Kingdom, this article demonstrates how socioscientific material is marginalized through the structures and language of syllabus texts and through classroom practices. This means students are unlikely to engage with socioscientific aspects in their course. Socioscientific content is gendered through association with social concerns and epistemological uncertainty, and because gender is asymmetric, socioscience is devalued with respect to the masculinity of abstract science. Teachers fear that extensive coverage of socioscience devalues the curriculum, alienates traditional science students and jeopardizes their own status as gatekeepers of scientific knowledge. Thus, although STS curricula such as Salters' offer potential for making science more accessible, the article concludes that greater awareness of, and challenges to, gender binaries could result in more effective STS curriculum reform. © 2000 John Wiley & Sons, Inc.

In science education, students should come to understand the nature and significance of models. In the case of chemistry education it is argued that the present use of models is often not meaningful from the students' perspective. A strategy to overcome this problem is to use an authentic chemical modelling practice as a context for a curriculum unit. The theoretical framework for this strategy is activity theory rooted in socio‐cultural theories on learning. An authentic chemical modelling practice is characterized by a set of motives for model development through a well‐defined modelling procedure using only relevant issue knowledge. The aim of this study was to explore, analyse, and select authentic chemical modelling practices for use in chemistry education. The suitability of the practices was reviewed by applying a stepwise procedure focused on criteria such as students' interest and ownership, modelling procedure, issue knowledge, and feasibility of the laboratory work in the classroom. It was concluded that modelling drinking‐water treatment and human exposure assessment are both suitable to serve as contexts, because both practices exhibit clear motives for model construction and the applied modelling procedures are in line with students' pre‐existing procedural modelling knowledge. The issue knowledge involved is consistent with present Dutch science curriculum, and it is possible to carry out experimental work in the classroom for model calibration and validation. The method described here to select and evaluate practices for use as contexts in chemistry education can also be used in other science domains. 相似文献

The extent to which students profit from a university course depends on the lecturers?? approach to teaching, with a student-focused approach being more supportive for student gains in competences than a teacher-focused approach. Little is known, however, about how to foster a student-focused approach to teaching. In this paper, we want to investigate how to frame the feedback lecturers obtain from students?? course evaluations in such a manner that a student-focused approach to teaching is encouraged. In two studies using either a qualitative or a quantitative methodology it can be shown that providing lecturers with a feedback on students?? subjective gain in competences (output-focused teaching evaluation) is more effective in promoting a student-focused approach to teaching than a feedback on how satisfied students were with the lecturer (process-focused teaching evaluation). Results are discussed in the context of the Bologna reforms which demand a continuous evaluation of all university courses. 相似文献

Many science teachers are presented with the challenge of characterizing science as a dynamic, human endeavour. Perspectivism, as a hermeneutic philosophy of science, has the potential to be a learning tool for teachers as they elucidate the complex nature of science. Developed earlier by Nietzsche and others, perspectivism has recently re-emerged in the context of the philosophy of science in the work of Ronald Giere. Giere presents a compelling case that scientific theories and scientific observation are perspectival by using science itself. There are many tangible examples already present in science textbooks which, when approached in a certain way, offer an exciting opportunity for a realistic incorporation of philosophy of science into the classroom. Furthermore, introducing perspectivism to students necessitates an engagement with notions such as truth, reality, perception and experimentation, through a familiar medium, while painting a nuanced conception of the nature of science. 相似文献

In the public discussion of genetically modified (GM) food the representations of science as a social good, conducted in the public interest to solve major problems are being subjected to intense scrutiny and questioning. Scientists working in these areas have been seen to struggle for the position of science in society. However few in situ studies of how the debate about science appears in learning situations at the university level have been undertaken. In the present study an introductory course in biotechnology was observed during one semester, lectures and small group supervision concerning GM food were videotaped and student’s reports on the issue were collected. The ethnographic approach to Discourse analysis was conducted by means of a set of carefully selected and representative observations of how a group of students learn to argue and appropriate views held in the Discourse they are enculturated into. While socio-scientific issues (SSIs) are often associated with achieving scientific literacy in terms of “informed decisions” involving “rational thought and Discourse” this study shows that SSI in practice, in the context studied here, is primarily concerned with using scientific language to privilege professional understandings of GMOs and discredit public worries and concerns. Scientific claims were privileged over ethical, economical and political claims which were either made irrelevant or rebutted. The students were seen to appropriate a Discourse model held in the biotechnological community that public opposition towards GMO is due to “insufficient knowledge”. The present study offers insights into biotechnology students’ decision making regarding socio-scientific issues, while also demonstrating the utility of Discourse analysis for understanding learning in this university context. Implications for reflection on the institutional Discourse of science and teaching of controversial issues in science are drawn and the study contributes to the investigation of claims of scientific literacy coupled to SSIs and argumentation 相似文献
