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.”

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

Delayed Understanding and Staying in Phase: Students’ Perceptions of their Study Situation 总被引:1,自引:0,他引:1
Max Scheja 《Higher Education》2006,52(3):421-445
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

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
