New representational technologies, such as virtual microscopy, create new affordances for medical education. In the article, a study on the following two issues is reported: (a) How does collaborative use of virtual microscopy shape students’ engagement with and learning from virtual slides of tissue specimen? (b) How do visual and conceptual cues scaffold students’ reasoning? Fifteen pairs of medical students participated in two sessions in which the students used a virtual microscope as a diagnostic tool in the context of learning pathology. The slides provided the students with varying levels of visual and conceptual cueing. The sessions were videotaped, and the students’ reasoning while using the microscope was analysed. The students’ written answers were analysed in terms of the findings they made and the diagnoses suggested. At a general level, the results show that students engage actively in this kind of virtually-mediated environment. The visual and/or conceptual cues improve students’ performance, and guide the students’ perception and reasoning in a manner that is productive from the point of view of learning to make clinically relevant observations. Scaffolding students’ reasoning process through cues furthermore assists the students in avoiding the most obvious pitfalls such as overlooking critical areas of a specimen. Overall, visual and conceptual cues improve students’ reasoning in perceptual and cognitive terms, while still allowing space for the making of “relevant mistakes” that may further the students’ diagnostic skills.  相似文献

This study investigated the effects of engaging students to collectively learn and work with knowledge in a computer-supported collaborative learning environment called Knowledge Forum on their views about knowledge building theory and practice. Participants were 24 teacher-education students who took a required course titled “Integrating Theory and Practice in Teaching.” Data mainly came from (1) student discourse recorded in a Knowledge Forum database, (2) a survey that examined students’ views about knowledge building, and (3) interviews with regard to students’ perceived barriers to implementing knowledge building theory in teaching. Findings suggest that with sustained discourse to construct their collective understanding of the relationships between theory and practice in teaching for a semester, the participants were able to attain more informed and practical views about knowledge building theory. In addition, students’ perceived barriers to implementing knowledge building in teaching were identified and strategies to help overcome these barriers discussed.  相似文献

The purpose of this mixed methods sequential explanatory study was to identify factors contributing to students’ persistence in the University of Nebraska-Lincoln Distributed Doctoral Program in Educational Leadership in Higher Education by obtaining quantitative results from surveying 278 current and former students and then following up with four purposefully selected typical respondents to explore those results in more depth. In the first, quantitative, phase, five external and internal to the program factors were found to be predictors to students’ persistence in the program: “program”, “online learning environment”, “student support services”, “faculty”, and “self-motivation”. In the qualitative follow up multiple case study analysis four major themes emerged: (1) quality of academic experiences; (2) online learning environment; (3) support and assistance; and (4) student self-motivation. The quantitative and qualitative findings from the two phases of the study are discussed with reference to prior research. Implications and recommendations for policy makers are provided.  相似文献

This article is written to inspire curriculum developers to centre their efforts on the learning processes of students. It presents a learning-based paradigm for higher education and demonstrates the close relationship between curriculum development and students’ learning processes. The article has three sections: Section “The role of higher education (HE) institutions” presents a discussion of the role of higher education in the knowledge society. Section “Contextual learning” presents the paradigm of contextual learning which we see as a useful foundation for curriculum development. Section “Curriculum development in practice—the BETA course” shows how a particular course in Business Economic Theory and Analysis has been developed using this paradigm. The article will be of interest to all academics interested in students’ learning processes but is especially relevant to those responsible for curriculum development.  相似文献

Educational researchers have suggested that computer games have a profound influence on students’ motivation, knowledge construction, and learning performance, but little empirical research has targeted preschoolers. Thus, the purpose of the present study was to investigate the effects of implementing a computer game that integrates the prediction-observation-explanation (POE) strategy (White and Gunstone in Probing understanding. Routledge, New York, 1992) on facilitating preschoolers’ acquisition of scientific concepts regarding light and shadow. The children’s alternative conceptions were explored as well. Fifty participants were randomly assigned into either an experimental group that played a computer game integrating the POE model or a control group that played a non-POE computer game. By assessing the students’ conceptual understanding through interviews, this study revealed that the students in the experimental group significantly outperformed their counterparts in the concepts regarding “shadow formation in daylight” and “shadow orientation.” However, children in both groups, after playing the games, still expressed some alternative conceptions such as “Shadows always appear behind a person” and “Shadows should be on the same side as the sun.”  相似文献

The purpose of the study is to compare problem based learning (PBL) and lecture-based learning (LBL) in Hong Kong secondary students’ science achievement. Secondary One students were divided into two groups: group A (n = 37), was taught two topics: “Human Reproduction” and “Density” through PBL; group B (n = 38) was taught the same topics by LBL. Multiple choice questions and short structured response items were used to assess students’ academic performance. Pre and post tests were categorized into three domains: knowledge, comprehension and application according to Bloom’s Taxonomy (Bloom 1956). The results of this study suggest first that PBL is at least as effective as LBL in gaining the knowledge required to achieve the syllabus’ learning objectives; secondly, the PBL group shows a significant improvement in students’ comprehension and application of knowledge over an extended time. Seemingly, PBL is favored for knowledge retention compared to a more conventional teaching approach, by these early adolescent children in Hong Kong. An ongoing longitudinal study on students’ interactions will further determine whether students taught through PBL develop improved learning in relation to high order skills, in a local situation which still tends to focus on factual recall but where higher skills are being demanded by systemic reform.  相似文献

Components of Conceptual Ecologies   总被引:1,自引:0,他引:1  
The theory of conceptual change is criticized because it focuses only on supposed underlying logical structures and rational process processes, and lacks attention to affective aspects as well as motivational constructs in students’ learning science. This is a vast underestimation of the complexity and diversity of one’s change of conceptions. The notion of conceptual ecology provides a context for understanding individuals’ conceptual change learning, as it is the environment through which all information is interpreted. This research investigated how high school students’ statements, made in answering questions, reflect selected components of their conceptual ecologies. Data for this study was collected from six interviews in which seven students took part. The data also include the science teacher’s profiles of each student, the students’ personal journals, their assignments, and their examinations and answers in class. The analysis presented will here include only those components that were represented in the discourse of the seven high school students who were interviewed. When students were asked questions, there was evidence of the engagement of the various components of conceptual ecologies. These components include: epistemological commitments, metaphysical beliefs, the affective domain and emotional aspects, the nature of knowledge, the nature of learning, the nature of conceptions, and past experience. Evidence from this study suggests that these components might function as constraints to learning. This study contributes to the field by expanding our knowledge of the components of high school students’ conceptual ecologies through its definition of the categories and themes associated with those components. In examining across the range of components, the study illustrates the variety and sources of science conceptions within high school students’ conceptual ecologies.  相似文献

This study explored the influence of residency status (outsider) and prior cross-cultural experiences on how the neighborhoods of students are perceived by future teachers. The study participants consisted of 18 graduate teacher education mentors and their 18 high school mentees. The data sources included 820 black and white photographs and 82 photo captions generated by the study participants, mentee/mentor group discussions, and the graduate students’ weekly reflective journals, bi-weekly facilitated discussions and peer debriefings. The study found that subconscious realities based on prior cross-cultural experiences (or the lack thereof) are more significant factors than residency status when making value judgment about the neighborhoods of “others.” Elinor L.

This paper responds to Schademan’s “What does playing cards have to do with science? A resource—rich view of African American young men”, and takes a resource-rich view to explore the notion of agency and elements of cultural resources that minority and marginalised students bring to the classroom. The paper examines the deficit model, the need to adopt capacity building perspective, and a classroom study, which sought to contextualise capacity building with a group of Australian indigenous students in a science class. As science educators, we need to reject the deficit model by developing capacity building pedagogies that affirm minority and marginalised students’ lived languages, experiences and knowledge in their learning.  相似文献

Learning no longer takes place as effectively as it did before in most current Korean classrooms. Many teachers have voiced concerns about a notably reduced level of students’ interest in and enthusiasm for learning school materials, lack of students’ attention to their lectures, and lack of students’ involvement in classroom activities. This negative change, which has been observed since around 1997, is often referred to as “school collapse” in Korea, meaning classroom breakdown. The paper investigates the factors that have lead to the phenomenon of the school collapse, introduces the 7th National Curriculum as one of the new reform approaches of the Korean government, and makes some suggestions to ensure more autonomy and diversity in classrooms to promote effective teaching and learning.  相似文献

Findings are presented from a study of undergraduate students’ experiences of understanding in first-year engineering. At the end of their first year of study 86 Swedish students of electrical engineering and computer science were asked to reflect in writing on their experiences of studying and learning. Fifteen of them also took part in interviews which explored in some detail their experiences of understanding in relation to perceived constraints of the teaching-learning environment. The analyses of the students’ written accounts and the interview data focused on the students’ experiences of studying and of understanding in relation to course work in engineering. The majority of the students reported problematic first-year experiences and testified to a sensation of ‘falling out of phase’ with their studies. This sensation was frequently coupled with a lag in coming to understand course material, which may be characterised in terms of delayed understanding. The notion of delayed understanding is discussed in relation to ideas about students’ perceptions of the learning environment and the impact that those perceptions might have on students’ opportunities to reflect on learning material and develop a solid understanding of course material in engineering education. In conclusion, it is suggested that the the notion of delayed understanding captures the complications of a study situation in which a perceived lack of time to reflect on learning material obstructs students’ understanding of course material in engineering, and also points up a more general aspect of learning observing that time to reflect on previous experiences is an essential component of the process of coming to understand learning material in a particular educational setting.  相似文献

This paper presents the findings of an interview study of first-year engineering students’ approaches to study. Data is presented to illustrate the construct of “dissonant study orchestration” as it is manifested in the everyday academic reality of these students’ learning behaviour. This data is theorised within a student’s-experiences-oflearning framework and patterns of study approach considered atypical of or theoretically undesirable within, the model used to determine them are presented and discussed. Individual-level, qualitatively different patterns of “dissonant” orchestration are articulated. The conclusion to the paper argues that the qualitative distinctions apparent amongst dissonant approaches present particular challenges to academic practitioners whose aim is the improvement of these students’ learning behaviour.  相似文献

In the framework of the SAL (Students’ approaches to learning) poosition, the learning experience (approaches to learning and study orchestrations) of 572 high school students was explored, examining its interrelationships with some personal and familial variables. Three major results emerged. First, links were found between family’s intellectual climate and students’ approaches to learning, in particular with Deep appraoch: The better the family’s intellectual climate the higher student’ scores on Deep approach. Second, along with general intelligence, these approaches predicted students’ academic achievement, higher grades being obtained by these students who scored lower in Surface learning approach and higher in Deep learning approach. Three, students from the four study orchestrations reported in previous research (two displaying conceptual consonance: Deep and Surface approaches, and the other two conceptual dissonance: high-high and low-low, in both Deep and Surface approaches) showed different profiles in some variables (e.g., metacognitive learning strategies, family’s intellectual climate, academic achievement), worse scores being obtained by those who orchestrated their study either in surface or in conceptually dissonant ways. These relationships shed more light on the nature of high school students ‘learning experience, and help to provide an integrated view of students’ webs of experience.  相似文献

This forum explores and expands on Ben-Zvi Assaraf, Eshach, Orion, and Alamour’s article titled “Cultural Differences and Students’ Spontaneous Models of the Water Cycle: A Case Study of Jewish and Bedouin Children in Israel” by examining how indigenous knowledge is appropriated in science classrooms; how students from indigenous students’ experiences are more complex than many non-indigenous students; and how science and globalization complicates the preservation of indigenous knowledge. In this forum we suggest that research on indigenous knowledge be examined through the lens of the locally situated contexts and the extent to which globalization hinders this kind of knowledge in the name of value neutral scientific knowledge. We finally suggest that research in indigenous communities has to be more intentional and respectful, and teachers need to rethink how useful and meaningful science learning can be for indigenous students.  相似文献

This article reports research from a 3 year digital learning project to unite conceptual change and scientific reasoning in the learning unit of combustion. One group of students had completed the course combining conceptual change and scientific reasoning. The other group of students received conventional instruction. In addition to the quantitative data, six students from each group were interviewed to evaluate their conceptual change, correct concepts and scientific reasoning. Results indicate that the experimental group’s students significantly outperformed the conventional group on the Combustion Achievement Test (CAT), Scientific Reasoning Test (SRT) and Combustion Dependent Reasoning Test (CDRT). Moreover, the experimental group’s students use higher levels of scientific reasoning more frequently and changed their alternative concepts more successfully than did the conventional group. Furthermore, once the experimental group’s students’ successfully changed their conceptions, their concepts tended to be more stable than the conventional group’s students, even after the 6th week of learning. These results demonstrate that combining conceptual change and scientific reasoning indeed improves students’ conceptual change and scientific reasoning ability more effectively than conventional instruction.  相似文献

The present study explores students’ abilities in conversions between geometric and algebraic representations, in problem- solving situations involving the concept of “limit” and the interrelation of these abilities with students’ constructed understanding of this concept. An attempt is also made to examine the impact of the “didactic contract” on students’ performance through the processes they employ in tackling specific tasks on the concept of limit. Data were collected from 222 12th-grade high school students in Greece. The results indicated that students who had constructed a conceptual understanding of limit were the ones most probable to accomplish the conversions of limits from the algebraic to the geometric representations and the reverse. The findings revealed the compartmentalized way of students’ thinking in non-routine problems by means of their performance in simpler conversion tasks. Students who did not perform under the conditions of the didactic contract were found to be more consistent in their responses for various conversion tasks and complex problems on limits, compared to students who, as a consequence of the didactic contract, used only algorithmic processes.  相似文献

This forum discussion focuses on seven themes drawn from Sonya’s fascinating paper: the terminology of “cogenerative dialogues,” the roles of participants and their power relations within such dialogues, the use of metaphor and analogy in the paper, science and science education for all students, the ways in which students’ expectations about learning change in innovative classrooms, teacher research and the “theory-practice gap,” and the tension between conducting cogenerative dialogues with individual students or with whole classes. These themes by no means exhaust the ideas in Sonya’s paper, but we feel that they have allowed us to explore the classroom research she reports, and to extend our discussion beyond the paper to explore some of these themes more broadly.  相似文献

In Uganda, curbing the spread of HIV/AIDS has largely depended on public and private media messages about the disease. Media campaigns based on Uganda’s cultural norms of communication are metaphorical, analogical and simile-like. The topic of HIV/AIDS has been introduced into the Senior Three (Grade 11) biology curriculum in Uganda. To what extent do students’ pre-conceptions of the disease, based on these media messages influence students’ development of conceptual understanding of the disease, its transmission and prevention? Of significant importance is the impact the conceptions students have developed from the indirect media messages on classroom instruction on HIV/AIDS. The study is based in a theoretical framework of conceptual change in science learning. An interpretive case study to determine the impact of Ugandan students’ conceptions or perceptions on classroom instruction about HIV/AIDS, involving 160 students aged 15–17, was conducted in four different Ugandan high schools: girls boarding, boys boarding, mixed boarding, and mixed day. Using questionnaires, focus group discussions, recorded biology lessons and informal interviews, students’ preconceptions of HIV/AIDS and how these impact lessons on HIV/AIDS were discerned. These preconceptions fall into four main categories: religious, political, conspiracy and traditional African worldviews. Results of data analysis suggest that students’ prior knowledge is persistent even after biology instructions. This has implications for current teaching approaches, which are mostly teacher-centred in Ugandan schools. A rethinking of the curriculum with the intent of offering science education programs that promote understanding of the science of HIV/AIDS as opposed to what is happening now—insensitivity to misconceptions about the disease—is needed.  相似文献

Patterns of Variation in Teaching the Colour of Light to Primary 3 Students   总被引:1,自引:0,他引:1  
This paper shows how the patterns of variation created in the teaching were critical in helping a class of Primary 3 students in Hong Kong to learn about the colour of light, so that the students attained conceptual rather than procedural knowledge. A ‘Learning Study’ approach was adopted, which is a Lesson Study grounded in a particular learning theory to improve teaching and learning. This study, based on the learning theory of Variation advanced by Marton and Booth, was premised on three types of variation: variation in students’ ways of experiencing what is to be taught/learnt (V1), variation in teachers’ ways of dealing with the ‘object of learning’ (V2), and the use of ‘pattern of variation’ as a guiding principle of pedagogical design to enhance students’ learning (V3). In planning the lesson, a conscious effort was made to create relevant patterns of variation, i.e. varying certain critical aspect(s) while keeping other aspects of the object of learning invariant in order to help students to discern those aspects. Comparison between the results of the pre- and post-test shows that there was significant gain in the students’ learning outcomes with respect to the intended object of learning. The findings contribute knowledge to how the Theory of Variation can be used in practice. It also illustrates how teachers can make use of this theoretical framework to analyze their own teaching and thereby, develop an analytical awareness of teaching and learning.  相似文献
