The Threshold Concept Framework is used to initiate a dialogue on an empirically supported pedagogy that focuses on students’ conceptual understanding required for solving application-based problems. The present paper uses a triangulation approach to identify the threshold concept in a third-year undergraduate civil engineering course on open channel hydraulics. Evidence from teachers, students, and assessment data point to ‘critical flow’ as the threshold concept – a concept that is transformative, integrative, and troublesome. Identifying the threshold concept by engaging various course stakeholders in a dialogue about conceptual understanding and capabilities makes learning visible for all participants in the process. Implementing this approach can result in an empirically driven rationale for adjusting pedagogies and assessments to foster enhanced student learning outcomes.  相似文献

This paper traces the development over several years of an initiative involving student journals that was introduced into a tertiary science education course for pre‐service teachers to promote enhanced learning of how to teach science. Very soon after introducing the journals into course work the lecturer began engaging in ‘unplanned’ informal reflection (reflection‐in‐action and reflection‐on‐action) when she witnessed the shallow, often trivial nature of her students’ reflective writing and the lack of pedagogical insights they were gaining from the exercise. Motivated by her own ongoing scholarship the lecturer introduced purposeful coaching of reflective skills into her pedagogy to scaffold students’ learning and promote more useful reflection. The impact of these interventions on students’ reflective capabilities and learning were investigated using a formal action research cycle. Findings indicate that student teachers’ reflective skills improved and resulted in deeper and more focused thinking about how to teach science for learning.  相似文献

This case study investigates the development of the understanding of constructivist theory among students in a Masters level elementary teacher education program within a particular course. The focus of the study is a seminar entitled ‘Advanced Seminar in Child Development’. The questions explored include: How do students’ ideas of teaching, learning and knowledge develop within the context of their experience in this course? How do they come to understand constructivism? What are their definitions of constructivism? What is the course of the development of this understanding? The nature of the students’ learning processes is examined through three sources of data: dialog journals, videotaped sessions and the instructor’s reflective teaching journal. The study looks both at student development and instructional practice to further understanding of how student‐teachers can learn to apply constructivist theory to their teaching and to understand the learning process, both within themselves and their students. Their development is placed in the context of Korthagen and Kessels’s model of teacher understanding and practice, and within a broader context of principles of practice that emphasize a belief in equity and social justice. The case illustrates how the way student‐teachers are taught theory can help them integrate their own ideas of learning and teaching with constructivist theory in order to think critically about their own practice in an ongoing developmental manner.  相似文献

Thought experiments are tools often used by physicists. Learning authentic physics then also means that students need to develop a familiarity with the reasoning processes of thought experiments. This study examines the nature of learning processes that involve communication about image‐based micro‐worlds in optics. The results of this study show that students’ investigations often have the structure of thought experiments. Thought experiments that use computer‐based microworlds are powerful because they capitalize on the human capability for imagery that allow learners to ‘see’ the physical processes and construct qualitative understandings. In this study, the structure of students’ activities as thought experiments arose from their collective efforts which started with the construction of an optics simulation. In the course of the activities, students’ understanding evolved from fragmented views of optical situations to system views that included multiple components. Collaborative thought experiments are therefore emergent phenomena, triggered by the events as a whole rather than being pre‐designed. In the course of the activities, students who participated in collective problem solving gradually adopted shared graphical representations and meanings.  相似文献

The increased availability of computational modeling software has created opportunities for students to engage in scientific inquiry through constructing computer‐based models of scientific phenomena. However, despite the growing trend of integrating technology into science curricula, educators need to understand what aspects of these technologies promote student learning. This study used a multi‐method research approach involving both quantitative (Paper 1) and qualitative data (Paper 2) to examine student conceptual understanding of astronomical phenomena, relative to two different instructional experiences. Specifically, based on students' understandings of both spatial and declarative knowledge, we compared students who had constructed three‐dimensional computational models with students who had experienced traditional lecture‐based instruction. Quantitative analysis of pre‐interview and post‐interview data revealed that construction of three‐dimensional models best facilitated student understandings of spatially related astronomical concepts — whereas traditional instruction techniques best facilitated student understandings of fact‐oriented astronomical knowledge. This paper is the first in a two‐paper set that continues our line of research into whether problem‐based courses such as the Virtual Solar System course can be used as a viable alternative to traditional lecture‐based astronomy courses.  相似文献

The report describes a study of the teaching behaviour of student‐teachers of science disciplines during the one‐term teaching practice of the English ‘Post‐Graduate Certificate in Education’ course, using the Science Teaching Observation Schedule by Eggleston et al.

The results suggest that in several behavioural dimensions, students and teachers achieve a close match. These dimensions, it is suggested, could represent the ‘stable’ elements in the students’ perception of science teacher behaviour learnt during their time as pupils, or they might represent ‘safe’ transactions which do not involve students extensively in problems of classroom management and control.

For other behaviour categories, it was found that students tended to behave less like experienced teachers as the training practice proceeded, but this was to some extent determined by the subject taught. Physics student‐teachers substantially maintained their similarity to experienced teachers, whilst chemistry and biology students drifted away. The nature of these drifts is discussed.  相似文献

The purpose of this study was to construct and study the impact of a research‐based sequence for teaching the concept of modelling to seventh‐grade science students. We identified students' notions of models and the aspects of school science to be addressed regarding the model concept, which were then taken into account when we planned the learning sequence. The idea of modelling in science was taught while the students were learning about the change of states of matter in seventh‐grade physics. A pre‐interview revealed that the students' notions of models were very limited, while a post‐interview showed that this improved in the course of the series of lessons. There was also a statistically significant difference in the students' understanding of modelling between our target group and a control group consisting of ninth‐grade students who had received only the normal teaching. However, a delayed post‐questionnaire completed a few months after the teaching sequence showed that the stability of learning results were dependent on whether models and modelling were used in the normal teaching conducted after the teaching sequence. Implications for teaching, teacher education and research are also addressed in this paper.  相似文献

In general, mathematical representations such as formulae, numbers, and graphs are the inseparable components in science used to better describe or explain scientific phenomena or knowledge. Regardless of their necessity and benefit, science seems to be difficult for some students, as a result of the mathematical representations and problem solving used in scientific inquiry. In this regard, several studies have attributed students’ decreasing interest in science to the presence of these mathematical representations. In order to better understand student learning difficulties caused by mathematical components, the current study investigates student understanding of a familiar science concept and its mathematical component (pH value and logarithms). Student responses to a questionnaire and a follow-up interview were examined in detail. “Measure” and “concentration” were key criteria for students’ understanding of pH values. In addition, only a few students understood logarithms on a meaningful level. According to students’ understanding of scientific phenomena and mathematical structures, five different student models and the critical features of each type were identified. Further analysis revealed the existence of three domains that characterize these five types: object, operation, and function. By suggesting the importance of understanding scientific phenomena as a “function,” the current study reveals what needs to be taught and emphasized in order to help students obtain a level of scientific meaning that is appropriate for their grade.  相似文献

Journal entries submitted by thirteen Doctor of Education students as a course requirement were analysed in order to explore the nature and content of their reflection and the effectiveness of journal writing in facilitating student learning. The findings confirm that journal writing encourages students to engage cognitively and reflectively with course concepts and content and to make connections between their academic learning and their personal/professional experience. Marked individual differences in response styles were apparent and these impacted on the learning outcomes reported by students. An ‘analytic’ approach to journal writing helps students to clarify, organise, evaluate and personalise ideas, an ‘extracting’ approach provides a useful record of ideas and issues, and an ‘affective’ approach encourages freedom of expression and self‐evaluation. Students who adopt a ‘course‐feedback’ style, however, receive little benefit from the activity. Suggestions are made for improving the effectiveness of student journals as a learning technique.  相似文献

In educational contexts, understanding the student’s learning must take account of the student’s construction of reality. Reality as experienced by the student has an important additional value. This assumption also applies to a student’s perception of evaluation and assessment. Students’ study behaviour is not only determined by the examination or assessment modes that are used. Students’ perceptions about evaluation methods also play a significant role. This review aims to examine evaluation and assessment from the student’s point of view. Research findings reveal that students’ perceptions about assessment significantly influence their approaches to learning and studying. Conversely, students’ approaches to study influence the ways in which they perceive evaluation and assessment. Findings suggest that students hold strong views about different assessment and evaluation formats. In this respect students favour multiple‐choice format exams to essay type questions. However, when compared with more innovative assessment methods, students call the ‘fairness’ of these well‐known evaluation modes into question.  相似文献

The paper reports a study for determining a suitable process for converting traditional surface science courses into case‐based learning ones in two universities in Hong Kong. In this preparative study, a set of baseline data was collected on the current level of students’ conceptual understanding and also students’ perceptions about the traditional courses. The student data (from 38 students) came from examination results, the Study Process Questionnaire, a course‐end survey and a focus group meeting; teachers also kept reflective journals. This set of baseline data revealed factors that both support and inhibit case‐based learning. On the one hand, students demonstrate a motivation to be able to solve practical problems in this field; on the other hand, they show an unwillingness to take up a personal responsibility for learning. This finding strengthens our resolve to take into account students’ expectations and beliefs in the implementation of case‐based teaching and learning.  相似文献

Background: Literature contends that a teacher’s knowledge of concept map-based tasks influence how their students perceive the task and execute the creation of acceptable concept maps. Teachers who are skilled concept mappers are able to (1) understand and apply the operational terms to construct a hierarchical/non-hierarchical concept map; (2) identify the legitimacy of the constructed concept map by verifying its graphical structure and its educational utility; and (3) determine the inherent ‘good’ and ‘poor’ qualities of the resulting graphical structure to reiterate the ‘good’ qualities and to coach and provide feedback to alleviate ‘poor’ qualities.

Purpose: The purpose of this study was to investigate the nature of prospective teachers’ knowledge underpinning the technique used to construct concept maps and thus, explicate their facility to construct concept maps.

Sample, Design and Methods: Data consisted of 200 concept maps constructed by prospective teachers in an elementary science methods course.

Results: Analysis revealed that the prospective teachers had predominantly constructed either hierarchical and/or non-hierarchical concept maps. It is likely that their maps reflect the teaching that they themselves would have experienced in their science classrooms during their own education. Additionally, most of these concepts maps only contained the root concept and subordinate concepts and lacked directional linking lines, linking phrases, labelled lines and propositions.

Conclusions: We argue that teacher educators need to assess their prospective teachers’ understanding of concept mapping in relation to the legitimacy (the nature and quality) of the end-products (graphical structures) of such practices. Prospective teachers also need to understand the educational utility of concept mapping in terms of how these end-products impact and/or effectuate learning.  相似文献

Preparing science and engineering students to work in interdisciplinary teams necessitates research on teaching and learning of interdisciplinary thinking. A multidimensional approach was taken to examine student interdisciplinary learning in a master course on food quality management. The collected 615 student experiences were analysed for the cognitive, emotional, and social learning dimensions using the learning theory of Illeris. Of these 615 experiences, the analysis showed that students reported 214, 194, and 207 times on, respectively, the emotional, the cognitive, and the social dimension. Per learning dimension, key learning experiences featuring interdisciplinary learning were identified such as ‘frustrations in selecting and matching disciplinary knowledge to complex problems’ (emotional), ‘understanding how to apply theoretical models or concepts to real-world situations’ (cognitive), and ‘socially engaging with peers to recognise similarities in perceptions and experiences’ (social). Furthermore, the results showed that students appreciated the cognitive dimension relatively more than the emotional and social dimensions.  相似文献

Co‐operative learning is underused as a teaching and learning strategy in higher education and yet is ideal for courses that require students to learn skills that require manual dexterity, knowledge and clinical reasoning – key elements of professional and clinical competence. Reciprocal peer coaching (RPC) is a form of co‐operative or peer‐assisted learning that encourages individual students in small groups to coach each other in turn so that the outcome of the process is a more rounded understanding and a more skilful execution of the task in hand than if the student was learning in isolation. Used as a formative assessment strategy, RPC has the capacity to increase motivation in students due to the nature of the shared interdependent goal, and to provide immediate feedback to students on completion of the assessment. The purpose of this research was to interview a group of first‐year students to elicit their perceptions of the RPC process. The data were analysed from a phenomenological perspective and revealed three themes: motivating learning, learning in groups and the context of learning. The findings were subsequently explored in relation to the concept of self‐regulation of learning and the benefits which RPC as a formative assessment strategy has in promoting students’ self‐regulation.  相似文献

Besides viewing knowledge about the nature of science (NOS) as important for its own value with respect to scientific literacy, an adequate understanding of NOS is expected to improve science content learning by fostering the ability to interrelate scientific concepts and, thus, coherently acquire scientific content knowledge. However, there is a lack of systematic investigations, which clarify the relations between NOS and science content learning. In this paper, we present the results of a study, conducted to investigate how NOS understanding relates to students’ acquisition of a proper understanding of the concept of energy. A total of 82 sixth and seventh grade students received an instructional unit on energy, with 41 of them receiving generic NOS instruction beforehand. This NOS instruction, however, did not result in students having higher scores on the NOS instrument. Thus, correlational analyses were performed to investigate how students’ NOS understanding prior to the energy unit related to their learning about science content. Results show that a more adequate understanding of NOS might relate to students’ perspective on the concept of energy and might support them in understanding the nature of energy as a theoretical concept. Students with higher NOS understanding, for example, seemed to be more capable of learning how to relate the different energy forms to each other and to justify why they can be subsumed under the term of energy. Further, we found that NOS understanding may also be related to students’ approach toward energy degradation—a concept that can be difficult for students to master—while it does not seem to have a substantive impact on students’ learning gain regarding energy forms, transformation, or conservation.  相似文献

In and with this text, I introduce the Forum that centers around a series of essays written by a high school student and an interview with his teacher all collected as part of a larger study about students’ discourses with respect to (nature of) science, learning, and knowing. I provide a brief review of the original findings, which had been published in a study co-authored by the student and myself, his physics teacher.  相似文献

This study examined the relationship between students' out‐of‐school experiences and various factors associated with science learning. Participants were 1,014 students from two urban high schools (secondary schools). They completed a survey questionnaire and science assessment describing their science learning experiences across contexts and science understanding. Using multilevel statistical modelling, accounting for the multilevel structure of the data with students (Level 1) assigned to teachers (Level 2), the results indicated that controlling for student and classroom factors, students' ability to make connections between in‐school and out‐of‐school science experiences was associated with positive learning outcomes such as achievement, interest in science, careers in science, self‐efficacy, perseverance, and effort in learning science. Teacher practice connecting to students' out‐of‐school experiences was negatively associated with student achievement but has no association with other outcome measures. The mixed results found in this study alert us to issues and opportunities concerning the integration of students' out‐of‐school experiences to classroom instruction, and ultimately improving our understanding of science learning across contexts.  相似文献

We present an inquiry‐based, aquatic science professional development (PD) for upper‐elementary, middle, and high school teachers and examine changes in student outcomes in light of participating teachers’ characteristics and the grade band of the students. Our study lends support to the assertion that inquiry‐ and content‐focused PD, paired with classroom implementation, can effectively improve student learning. Our findings indicate that students improved in their nature of science (NOS) and aquatic science content knowledge and that these changes depended in some ways on the participating teachers’ characteristics and adherence to the program. The students’ improvements were amplified when their teachers adhered more closely to the PD activities during their classroom implementation. The teachers’ previous science PD experience and pre‐PD understanding of inquiry‐based teaching also explained some of the variability in student growth. In both NOS and content, students of teachers with less prior science‐PD experience benefited more. Grade band also explained variation in student outcomes through interactions with teacher‐characteristic variables. In high school, students of teachers with lower pre‐PD inquiry knowledge appeared to learn more about NOS. Our results suggest that inquiry and content training through PD may minimize disparities in teaching due to inexperience and lack of expertise. Our study also demonstrates the value of PD that teaches a flexible approach to inquiry and focuses on underrepresented, interdisciplinary content areas, like aquatic science. © 2017 Wiley Periodicals, Inc.

Insights and Conflicts in Discussing Recursion: A Case Study   总被引：1，自引：1，他引：0  
Recursion is a significant concept, appearing in almost every introductory course in Computer Science (CS). CS educators and educational researchers often refer to difficulties in learning and teaching recursion. However, the research literature barely addresses the unique ways in which students relate to this interdisciplinary concept and the particular learners’ language concerning recursive phenomena. The gap is most apparent when seen through a constructivist lens, where the students’ prior knowledge and idiosyncratic conceptions should be referred to and reflected upon in order to serve as a basis for further knowledge construction. This paper reports on a study in which a collaborative classification of several recursive phenomena are used to facilitate the construction of recursion. The student discourse was recorded and analyzed, and a grounded categorical system was formed and examined. Preliminary results indicate some basic aspects of recursion in the student discourse, although the students apparently talk a very different language from that of the experts. Some ‘potentially rich’ discourse episodes were evident as well, representing conflicts among alternative conceptions. Such episodes can serve as a springboard for further learning.  相似文献
