A well‐developed and researched conceptual framework exists for identifying undergraduate students' conceptions of learning. In addition, research has been reported on teachers' conceptions of teaching as they relate to their conceptions of learning. The research reported in this paper takes the existing framework into a new area, postgraduate supervisors' conceptions of “research”. It is hypothesized that the development of a conceptual framework that identifies postgraduate students' conceptions of “research”, and how these articulate with the conceptions of research held by their research supervisors, will enable support mechanisms to be developed and used to assist students early in their candidature. In addition, supervisory practice will benefit from being aware of, and sensitive to, the variety and potential effect of these conceptions. While it is recognized that there are strong cultural influences on conceptions of research, this project has focused initially on the conceptions of research generally adopted by Western academic institutions. However, the students involved in the study were not necessarily of a Western educational background. This paper outlines the results of research undertaken to date in identifying supervisors' conceptions. In addition, it discusses supervisors' views on: the purpose of research and what characterizes “good” research and good researchers. Various strategies reported by supervisors to assist their students to develop more comprehensive and sophisticated conceptions of research are also discussed. 相似文献

The aim of the study was to discover the essential characteristics of engineering teachers' pedagogical content knowledge by studying teachers' conceptions of their students' ideas of moment. To compare the conceptions maintained by teachers with those of their students, the most common difficulties experienced by first-year engineering students in understanding the moments of forces were looked at. The data on students' conceptions were collected by means of a questionnaire. In addition, four experienced teachers were given the same questionnaire as the students and then were asked to write what they expected the students' answers to be. The students' answers and the teachers' conceptions of their students' potential answers were compared. It was found that although the teachers originally appeared to be familiar with their students' conceptions, they were rather astonished by the general pattern of the students' thinking. It is planned that the information gathered about the teachers' pedagogical content knowledge will eventually be used to improve engineering teacher training. 相似文献

This study examined structural characteristics of university engineering students' conceptions of energy elicited through paragraph writing and their relations with categories of their conceptions specific to energy in solution processes identified through interviews. We found that structures of students' conceptions are characterized primarily by characteristic, example‐of/type‐of, and lead‐to types of relations, and these relations correspond with categories of students' conceptions. More specifically, categories of students' conceptions are exclusively related to energy transformation, and students failed to apply the notion of energy conservation demonstrated in structures of their conceptions to explain the temperature change in solution processes. It is concluded that although paragraph writing and interviews solicit different student conceptions, the conceptions identified from the two sources are related and paragraph writing tends to provide a more holistic picture of students' conceptions. This conclusion has clear implications for science curriculum development and instruction. © 2002 Wiley Periodicals, Inc. J Res Sci Teach 39: 423–441, 2002 相似文献

As biotechnology‐related scientific advances, such as stem cell research (SCR), are increasingly permeating the popular media, it has become ever more important to understand students’ ideas about this issue. Very few studies have investigated learners’ ideas about biotechnology. Our study was designed to understand the types of alternative conceptions students hold concerning SCR. The qualitative research design allowed us to examine college students’ understandings about stem cells and SCR. More specifically, we addressed the following questions: How can alternative conceptions about stem cell topics be categorized? What types of alternative conceptions are most common? Participants included 132 students enrolled in a biotechnology course that focused on the scientific background of biotechnology applications relevant to citizens. In this study, we used an inductive approach to develop a taxonomy of alternative ideas about SCR by analyzing student responses to multiple open‐ended data sources. We identified five categories of conceptions: alternative conceptions about what, alternative conceptions about how, alternative conceptions about medical potential, terminology confusion, and political and legal alternative conceptions. In order to improve instruction, it is important to understand students’ ideas when entering the classroom. Our findings highlight a need to teach how science can be applied to societal issues and improve science literacy and citizenship. 相似文献

Policy‐makers' conceptions of teacher professionalism currently differ markedly in England and Finland. In England they are shaped by agendas associated with the drive to raise standards and ‘commercialized professionalism’ whilst in Finland they are influenced by notions of ‘teacher empowerment’. This article analyses findings on the theme of teacher professionalism derived from re‐interviewing a sample of English and Finnish teachers in 2001 as a follow‐up to earlier ethnographic research in six schools in each country during 1994–1996. Issues of professionalism are addressed through three broad themes: the impact of curriculum and pedagogical reforms; working together to implement these reforms; and accountability and control. It is argued that in each country teachers' conceptions of their professionalism were undergoing reconstruction. These conceptions were shaped by past and present ideology, policy and practice and displayed multiple and situational dimensions. 相似文献

Scientific literacy implies an adequate understanding of the nature of scientific knowledge. However, little is known about classroom factors that can influence students' conceptions of the nature of science. In the present study, classroom variables that were related to changes in students' conceptions of science were identified. Particular attention was directed toward students' overall conceptions of scientific knowledge and their views of its tentative nature. Twenty-five classroom variables were found to be significantly related to both overall and tentative conceptions, while 12 variables were found to be scale-specific. A comparison between teacher and student conceptions of science did not support the prevalent assumption that a teacher's conception of science is significantly related to changes in students' conceptions of science. “Successful” classes were defined as those exhibiting the greatest student conceptual changes toward the viewpoint held by the teacher, irrespective of the “adequacy” of the teacher's viewpoint. In general, these classes were typified by frequent inquiry-oriented questioning with little emphasis on rote memory. Implicit references to the nature of science were commonly observed. Furthermore, where greatest changes in student conceptions of science were observed, the teachers were pleasant, supportive, and frequently used anecdotes to promote instruction and establish rapport. Emphasis on the depth, breadth, and accuracy of content statistically differentiated between “successful” and “unsuccessful” classes with respect to students' overall conceptions. However, this emphasis on content presentation did not differentiate classes with respect to students' conceptions of the tentative nature of science. 相似文献

Drawings are often used to obtain an idea of children's conceptions. Doing so takes for granted an unambiguous relation between conceptions and their representations in drawings. This study was undertaken to gain knowledge of the relation between children's conceptions and their representation of these conceptions in drawings. A theory of contextualization was the basis for finding out how children related their contextualization of conceptions in conceptual frameworks to their contextualization of drawings in pictorial convention. Eighteen children were interviewed in a semi‐structured method while they were drawing the Earth. Audio‐recorded interviews, drawings, and notes were analysed to find the cognitive and cultural intentions behind the drawings. Also, even children who demonstrated alternative conceptions of the Earth in the interviews still followed cultural conventions in their drawings. Thus, these alternative conceptions could not be deduced from the drawings. The results indicate that children's drawings can be used to grasp children's conceptions only by considering the meaning the children themselves give to their own drawings. 相似文献

This paper looks at the effect of instruction on pre-service science teachers' conceptions of the scientist. Twenty-six pre-service science teachers involved in a 14-week course were the subjects. The constructivist teaching approach was adopted. The students' preconceptions were the starting point for the teaching. Seven students were selected for in-depth interview to determine the reasons for their positions (change or no change in view at the end of the period). It was found that instruction enhanced better conceptions of the scientist. The pre-test to post-test change scores differed from zero and the difference was significant at the 0·05 level of significance. However, the interview revealed that the changes in conceptions were mediated by the students' life worldviews. We therefore conclude that whereas remediating strategies enhance understanding (comprehension), worldview of the students has a greater effect on meaningful learning (apprehension). 相似文献

One of the factors affecting students' learning in science is their existing knowledge prior to instruction. The students' prior knowledge provides an indication of the alternative conceptions as well as the scientific conceptions possessed by the students. This study is concerned primarily with students' alternative conceptions and with instructional strategies to effect the learning of scientific conceptions; i.e., to effect conceptual change from alternative to scientific conceptions. The conceptual change model used here suggests conditions under which alternative conceptions can be replaced by or differentiated into scientific conceptions and new conceptions can be integrated with existing conceptions. The instructional strategy and materials were developed for a particular student population, namely, black high school students in South Africa, using their previously identified prior knowledge (conceptions and alternative conceptions) and incorporate the principles for conceptual change. The conceptions involved were mass, volume, and density. An experimental group of students was taught these concepts using the special instructional strategy and materials. A control group was taught the same concepts using a traditional strategy and materials. Pre- and posttests were used to assess the conceptual change that occurred in the experimental and control groups. The results showed a significantly larger improvement in the acquisition of scientific conceptions as a result of the instructional strategy and materials which explicitly dealt with student alternative conceptions. 相似文献

Research suggests that students' approaches to learning and hence learning outcomes are closely related to their conceptions of learning. This paper describes an investigation into conceptions of formal learning held by 22 Aboriginal and Torres Strait Islander students from three Australian universities in Queensland; categories of informal learning, reasons for studying and strategies used to learn were also investigated. The attrition rate for these students in tertiary education is higher than that of any other group of students. The main aim of this study was to determine their conceptions of learning in order to provide information that might facilitate instruction more suited to their needs in order to address the high attrition rate. Results showed that these students view and approach university learning in much the same way as other university students. It was also apparent that, for the most part, the strategies these students used did not match the conceptions of learning they held. An interesting result was the difference between the conceptions of formal learning and perceptions of informal learning. 相似文献

New learning theory, underpinning the idea of teaching for self-directed learning, provides new conceptions of learning: the self-regulation of learning, the construct-character of knowledge, the social nature of learning and a dynamic model of intelligence. What conceptions teachers hold may be related to their tolerance of uncertainty. We constructed a Learning Inventory and administered this to teachers in Dutch senior secondary education, where an innovation is heading for more independent learning. We found empirical confirmation of the five dimensions underlying teachers' conceptions of learning, both for student learning and for their own learning. Tolerance of uncertainty explained the other four dimensions in conceptions of student learning, but not in teachers' conceptions of their own learning. Teachers generally endorse the process-oriented conceptions, although some differences are noted between teachers' conceptions of student learning and their own learning. 相似文献

Case studies have been constructed of primary school children's developing explanations of a range of air pressure phenomena. A range of conceptions relating to air pressure have been identified, and insights gained concerning the way these interrelate over time and over context. It was found that children are naturally generative in their construction of explanations, but that they use conceptions in quite complex and fluid ways. It is argued that naive conceptions maintain a valuable function as intuitive recognition elements that feed more sophisticated conceptions, and that generating a satisfying explanation for a phenomenon can involve having access to a range of interrelated conceptions. A range of contextual factors were identified, which influence the construction of explanations, and can act as barriers to the application of scientific conceptions. 相似文献

This is a report on the investigation of a microcomputer-based system for the diagnosis and remediation of three Aristotelian alternative conceptions of force and motion held by eighth-grade physical science students. Diagnosis and posttesting were done with computer-displayed, graphics-based, multiple-choice questions. The two remediation simulations were designed to present scientific idealizations and to be perceived by the student as anomalous to the three alternative conceptions. Structured interviews were employed at several points during the study to obtain indications of the conceptions of force and motion of students with different achievement rankings, as well as to determine the students' reactions to the computer pretest questions or the simulations. A student's possession of alternative conceptions was unrelated to whether the student was a strong or weak learner of science. Students who were currently studying dynamics in their classes exhibited a very different pattern of nonscientific answers on the computer diagnostic test than did students who had completed that topic. The completed students who were selected for possession of alternative conceptions were facilitated by the computer simulations in altering their naive conceptions to a significant degree. 相似文献

Federal, state, and local policy makers' high-stakes standards-based accountability reforms are transforming the early childhood teacher education process. These reforms affect how early education teacher candidates figure their role as teachers. By employing Holland, Lachicotte, Skinner, and Cain's conception of figured worlds to analyze the findings of a qualitative case study, this article examines how three early childhood teacher candidates' figured conceptions of themselves as early educators evolve in high-stakes classrooms and teacher education environments. It also investigates how these candidates see themselves addressing these reforms in their own classrooms. Such a study not only further details the impact reforms have on preservice teachers' conceptions of teaching, but it also provides a chance for early childhood teacher educators to consider strategies they might employ to assist their candidates in developing a figured conception of teaching that addresses these reforms in an developmentally appropriate manner. 相似文献

This article analyses the experiences of women teachers in boys' schools by examining a case-study school. It is argued that whilst there had been a large numerical increase in women at the school, partly as the unanticipated consequence of recent government reforms, the degree of 'feminisation' was much smaller. Teaching style and negative pupils' reactions, undermining by colleagues, exclusion from staff meetings and sexual harassment emerged as important dimensions of these women's experience. The women were not a homogeneous group, however, and two ideal type groupings emerged which offered different interpretations of their situation, contrasting conceptions of what a feminised school would look like and different strategies for feminising the school. It is argued that for many of the women the women's group played an important role in enabling them to redefine their situation collectively. 相似文献

Students in part‐time courses were interviewed about their perceptions of good teaching and tutoring. The perceptions differed markedly between those with reproductive conceptions of learning and students holding self‐determining ones. The former preferred didactic teaching but disliked interaction, whereas the latter had almost diametrically opposite perspectives by finding student‐centred approaches consistent with their conceptions of learning. The findings have implications for the evaluation of teaching, as ratings are likely to be influenced by the predominant conceptions of learning of a class. It is common for individual instructors to be regularly evaluated by teacher evaluation questionnaires, which often have a teacher‐centred bias, and for the ratings to be used for appraisal. It is argued that this leads to conservatism as teachers fear that students with reproductive conceptions of learning will reduce their ratings if they innovate in their teaching. As the degree of bias from this ratings‐lowering phenomenon may be quite large, the findings are a caution against the common practice of using absolute rating values from both teacher evaluation questionnaires and programme‐level evaluation by instruments such as the Course Experience Questionnaire. Results need to be interpreted together with other evidence and take into account contextual factors including students' conceptions of learning. 相似文献

Teaching reform in higher education has frequently been informed by investigations into conceptions of learning held by students and by teachers. Such work has been extended into research education, with the study of experienced researchers' conceptions of research providing a basis for enquiry into the way research is experienced by the various participants in research education. This paper reports research designed to investigate research supervisors' conceptions of research as they were produced in focus group conversations. Using techniques of membership categorisation analysis, discourses are identified that privileged university‐based research and researchers over other forms of research and other ways of knowing, in particular over the interests of professional/practitioner researchers and over the legitimacy of research conducted in workplaces outside the university. It is argued that such discourses have the potential to be problematic for professional and industry‐based practitioner researchers as they seek to construct authoritative researcher identities. Further interrogation of the categorisation work that sustains these discourses offers the opportunity to make their assumptions explicit, which has implications for supervisors' reflective practice and professional development. 相似文献

The conceptions of learning that students hold and how these change are dependent on several factors, including their schooling, personal traits of students and the academic environment of the tertiary institute (e.g. departmental policies, attitudes and behaviour of staff). This document discusses whether the conceptions of learning students (in this case, second year medical students) hold can be related to their academic ability. From a phenomenographic perspective (Marton et al., 1993), it would appear that students who were selected in the present study for their good academic record expressed more transformative conceptions of learning than did their less academically achieving peers, who appeared to rely on memorisation and recall. Based on the results of this study, 'academic ability' might then be a reflection of the conceptions of learning students hold. It would be interesting to extend this study to include students in other disciplines, experiencing other curricula and at different year levels. 相似文献
