During the past 15 years, various studies have described factors affecting the use of computers in the classroom. In analysing factors of influence, many studies have focused on technology-related variables such as computer experience or attitudes toward computers, and others have considered teachers’ beliefs as well; most of them have studied undefined categories of teachers and focused on explaining the frequency of technology in classrooms. The present study centres on secondary history teachers’ teaching conceptions as a precursor to the ways in which they use computing technology in the classroom. The research is a qualitative study examining the theoretical assumption that teachers’ conceptions of teaching and learning guide their pedagogical action. Semi-structured interviews were conducted with 10 Chilean history teachers, and their didactic sequences were filmed extensively. The research found patterns among educational uses of technology in relation to teaching conceptions (defining the latter based on three conceptual groups: direct instruction or individual or social construction of knowledge) in terms of the allotment of time and the manner of teacher technology use, and less sharply defined patterns were also noted in student technology use and teacher–student–technology interactions.  相似文献

Growing recognition of the central importance of fostering an in‐depth understanding of natural selection has, surprisingly, failed to stimulate work on the development and rigorous evaluation of instruments that measure knowledge of it. We used three different methodological tools, the Conceptual Inventory of Natural Selection (CINS), a modified version of Bishop and Anderson's (Bishop and Anderson [1990] Journal of Research in Science Teaching 27: 415–427) open‐response test that we call the Open Response Instrument (ORI), and an oral interview derived from both instruments, to measure biology majors' understanding of and alternative conceptions about natural selection. We explored how these instruments differentially inform science educators about the knowledge and alternative conceptions their students harbor. Overall, both the CINS and ORI provided excellent replacements for the time‐consuming process of oral interviews and produced comparable measures of key concept diversity and, to a lesser extent, key concept frequency. In contrast, the ORI and CINS produced significantly different measures of both alternative conception diversity and frequency, with the ORI results completely concordant with oral interview results. Our study indicated that revisions of both the CINS and ORI are necessary because of numerous instrument items characterized by low discriminability, high and/or overlapping difficulty, and mismatches with the sample. While our results revealed that both instruments are valid and generally reliable measures of knowledge and alternative conceptions about natural selection, a test combining particular components of both instruments—a modified version of the CINS to test for key concepts, and a modified version of the ORI to assess student alternative conceptions—should be used until a more approprite instrument is developed and rigorously evaluated. © 2008 Wiley Periodicals, Inc.

Understanding bonding is fundamental to success in chemistry. A number of alternative conceptions related to chemical bonding have been reported in the literature. Research suggests that many alternative conceptions held by chemistry students result from previous teaching; if teachers are explicit in the use of representations and explain their content-specific forms and functions, this might be avoided. The development of an understanding of and ability to use multiple representations is crucial to students’ understanding of chemical bonding. This paper draws on data from a larger study involving two Year 11 chemistry classes (n = 27, n = 22). It explores the contribution of explicit instruction about multiple representations to students’ understanding and representation of chemical bonding. The instructional strategies were documented using audio-recordings and the teacher-researcher’s reflection journal. Pre-test–post-test comparisons showed an improvement in conceptual understanding and representational competence. Analysis of the students’ texts provided further evidence of the students’ ability to use multiple representations to explain macroscopic phenomena on the molecular level. The findings suggest that explicit instruction about representational form and function contributes to the enhancement of representational competence and conceptual understanding of bonding in chemistry. However, the scaffolding strategies employed by the teacher play an important role in the learning process. This research has implications for professional development enhancing teachers’ approaches to these aspects of instruction around chemical bonding.  相似文献

This qualitative study aimed at exploring whether students’ successful use of analogy in learning curriculum complex science concepts was related: (a) to the level of their understanding of a specific analogy and (b) to their metacognitive awareness of how the analogy was to be used and of the changes produced in their own conceptual structures. In implementing a biological curriculum unit, students’ prior knowledge has been taken into account in order to examine its conceptual growth and change via a not completely introduced analogy to 15 fifth graders as they were engaged in understanding the ways in which the new concepts (on photosynthesis) were similar to a familiar source (making a cake). Qualitative data present the children's mapping processes in elaborating the analogy and their metacognitive awareness of the meaning and purpose of the analogy itself, and their personal use of the analogy in changing initial conceptions. As hypothesised, the results showed a high positive correlation among the level of conceptual understanding of the new science topic, the level of understanding of the analogy, and the level of effective use of the analogy in integrating the new information into the pre‐existing conceptual structures. Key implications on the use of analogy for conceptual change in the classroom are outlined.  相似文献

We examine preservice mathematics teachers' conceptions of writing as a tool for learning mathematics before and after participation in and reflection on writing tasks. We describe the use of two targeted activities incorporated into a secondary methods course: writing to learn mathematics (WTLM) and reflection on that writing. Prior to participation in these activities, the preservice teachers expressed reluctance toward the use of writing in mathematics and uncertainty as to how writing could be useful in mathematics, while accepting that some possible benefits might exist for students' procedural learning. Following participation in these activities, the preservice teachers expressed a willingness to accept writing as a useful tool for supporting an expanded view of teaching and learning mathematics. Specifically, the preservice teachers considered writing as a way to build connections between mathematics and other subjects, a means to assess student understanding of mathematics, and a beneficial support for student conceptual learning.  相似文献

Identifying students’ conceptual scientific understanding is difficult if the appropriate tools are not available for educators. Concept inventories have become a popular tool to assess student understanding; however, traditionally, they are multiple choice tests. International science education standard documents advocate that assessments should be reform based, contain diverse question types, and should align with instructional approaches. To date, no instrument of this type targeting student conceptions in biotechnology has been developed. We report here the development, testing, and validation of a 35-item Biotechnology Instrument for Knowledge Elicitation (BIKE) that includes a mix of question types. The BIKE was designed to elicit student thinking and a variety of conceptual understandings, as opposed to testing closed-ended responses. The design phase contained nine steps including a literature search for content, student interviews, a pilot test, as well as expert review. Data from 175 students over two semesters, including 16 student interviews and six expert reviewers (professors from six different institutions), were used to validate the instrument. Cronbach’s alpha on the pre/posttest was 0.664 and 0.668, respectively, indicating the BIKE has internal consistency. Cohen’s kappa for inter-rater reliability among the 6,525 total items was 0.684 indicating substantial agreement among scorers. Item analysis demonstrated that the items were challenging, there was discrimination among the individual items, and there was alignment with research-based design principles for construct validity. This study provides a reliable and valid conceptual understanding instrument in the understudied area of biotechnology.  相似文献

The implementation of peer assessment (PA) in the classroom faces considerable interpersonal challenges. In this quantitative survey study (N = 225) we focus on the current use and format of PA among secondary education teachers in Flanders and explore teachers’ awareness of these interpersonal challenges. We validated an instrument for measuring teachers’ awareness which was then used to investigate how this awareness level relates to their conceptions of the educational value of PA. SEM results show that teachers are slightly to moderately aware with regard to their students’ concerns about the impact of interpersonal processes in PA as well as the importance students attribute to anonymity within PA. This study illustrates that teachers’ perceived accuracy of PA is a major predictor of their belief in its educational value and opens up a new avenue for research on teachers’ awareness of interpersonal processes in PA.  相似文献

Like their students, teachers may hold a variety of naïve conceptions that have been hypothesized to limit their ability to support students’ learning. This study examines whether changes in elementary students’ conceptions are related to their teachers’ content knowledge, attitudes, and understanding of conceptual change. The study takes place in the context of the adoption of a new unit on seasonal change in which students build and use sundials to observe seasonal differences in the apparent motion of the Sun across the sky. A mixed-method approach is used. Data sources include pre- and post-tests for students and teacher interviews and questionnaires. Results indicate that changes in students’ conceptions may be related to their teachers’ knowledge of the content, attitudes toward science, and understanding of conceptual change. One teacher had low attitude toward science and limited knowledge of conceptual change. After instruction, her students’ responses became less accurate but more homogeneous than before instruction. The other teacher had high attitude and moderate knowledge of conceptual change. Her students showed gains from pre- to post-test, including responses that were more scientifically accurate than the teachers’ initial answers.  相似文献

ABSTRACT

We assessed whether the level of time-pressure reported by a school’s teachers is predictive of student bullying perpetration. We combined data from two surveys conducted in 129 schools in 2016: the Stockholm School Survey performed among students in grades 9 and 11 (n?=?10,668), and the Stockholm Teacher Survey carried out among senior level (grades 7–9) and upper secondary school (grades 10–12) teachers (n?=?2259). Multilevel path analyses showed that teachers’ stress and time-pressure increased with declining school leadership functioning. Teachers’ level of time-pressure was, in turn, positively associated with student traditional and cyberbullying behaviour, through its effect on the school staff’s tendency (not) to intervene against bullying, but not through the teachers’ stress level. We conclude that schools with leadership that provides opportunities for the teachers to focus on their main mission can counteract bullying among the students and therefore indirectly also to promote student health.  相似文献

Evidence from large-scale studies of primary and secondary students’ technology practices at school over the last decade show disparities in student practices and suggest that schools need to do more to cater for all students. Research that explores the influence of social and cultural factors may be useful for understanding such inequality in student practice. Bourdieu’s theory of practice [(1977). Outline of a Theory of Practice. London: Cambridge University Press] is proposed as an example of a sociological theory that can be adopted in educational technology research to move towards understanding the wider complexities of technology practice. To encourage discourse and application of Bourdieu’s sociology in the field of educational technology research, this paper provides an introduction to the theory, a review of its application in research of primary and secondary students’ technology practice and relevant conceptual work. The paper presents a conceptual framework based on Bourdieu’s theory that has been developed through two recent studies, and review of empirical and conceptual works and invites its application in future research so that it can be critiqued and further developed.  相似文献

Adopting a two-phase explanatory sequential mixed methods research design, the current study examined the impact of student teaching experiences on pre-service teachers’ readiness for technology integration. In phase-1 of quantitative investigation, 2-level growth curve models were fitted using online repeated measures survey data collected from 68 pre-service teachers doing their student teaching. The results revealed significant progress in readiness for technology integration during student teaching and significant variability in individual change trajectories of readiness for technology integration. Two dummy variables, prior-teaching (0 = “having no prior teaching experience”; 1 = “having prior teaching experience”) and grade-level (0 = “elementary level”; 1 = “secondary level”), were identified as significant in predicting the shape of individual change trajectories of readiness for technology integration. In phase-2 of qualitative investigation, follow-up interview data were collected from 11 pre-service teachers among those who participated in the online surveys. The interview data was analyzed both deductively and inductively yielding clues and insights for interpreting and understanding the quantitative results from phase-1. Based on its quantitative and qualitative results, this study made recommendations for future technology integration research and for improving pre-service teachers’ technology use experience during student teaching.  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

The purpose of this study was to examine the effects of science education courses on a group of Taiwanese inservice and preservice teachers’ views toward the nature of science. There were two science education courses in the study; one was for 36 inservice teachers, while the other one was for 32 preservice teachers. Both of the courses included the philosophy of science, the instruction about student alternative conceptions and theories of conceptual change, and some classroom activities for science education. The data sources were based upon these teachers’ questionnaires, written responses to open-ended questions and interviews. The findings derived from this study revealed that both inservice and preservice teachers, to a certain extent, changed their views toward the nature of science when completing the courses. Many of them might reinterpret and reconstruct their views about science during the courses, and their views had progressed toward more constructivist-oriented. This study also suggested that the instruction about student alternative conceptions and conceptual change theories was more helpful than direct instruction about the philosophy of science in changing teachers’ views about science.  相似文献

Often, mathematics teachers do not incorporate whole-class discourse of students’ various ideas and solution methods into their teaching practice. Particularly complex is the in-the-moment decision-making that is necessary to build on students’ thinking and develop their collective construction of mathematics. This study explores the decision-making patterns of five experienced Dutch mathematics teachers during their novice attempts at orchestrating whole-class discourse concerning students’ various solution methods. Our goal has been to unpack the complexity of their in-the-moment decision-making during whole-class discourse through lesson observations and stimulated recall interviews. We investigated teacher decision-making adopting a model that combines two perspectives, namely (1) we explored student-teacher interaction with regard to building on student thinking and (2) we explored how the teachers based decisions during such interaction upon their own personal conceptions and interpretation of student thinking. During these novice attempts at orchestrating whole-class discourse, the teachers created many situations for students to articulate their thinking. We found that at certain instances, teachers’ in-the-moment decision-making resulted in opportunities to build on student thinking that were not completely seized. During such instances, the teachers’ decision-making was shaped by the teachers’ own conceptions of the relevant mathematics and by teacher conceptions that centered around student understanding and mathematical goals. Our findings suggest that teachers might be supported in their novice attempts at whole-class discourse by explicit discussion of the mathematics and of their conceptions with regard to student understanding and mathematical goals.

Understanding how well teachers integrate digital technology in learning is the subject of considerable debate in education. High Possibility Classrooms (HPC) is a pedagogical framework drawn from research on exemplary teachers’ knowledge of technology integration in Australian school classrooms. The framework is being used to support teachers who teach various stages of schooling to take ‘pedagogical steps’ in their practice with technology. This article focuses on the use of the HPC conceptual framework in a study of seven teachers and their students at two secondary schools in New South Wales, Australia. Analysis confirms the practicality of this conceptual framework for technology integration in secondary school classrooms. This inquiry has implications for addressing the reluctance of teachers to integrate technology in curriculum. The article concludes by suggesting that more schools might consider using conceptual frameworks like HPC to support secondary school teachers to enhance student learning with technology.  相似文献

Many teachers struggle to provide equitable opportunities for students with special educational needs (SEN) to learn science concepts in the inclusive classroom. This study examines the experience of teaching in an inclusive classroom using a conceptual change approach, the Thinking Frames Approach (TFA), incorporating the use of discrepant events, social construction of scientific conceptions followed by the production of multiple student‐generated representations of their understanding. An in‐depth case study is presented of the experience of Wayne, a student with complex SEN and the effect on his behaviour and science learning based on video/audio recordings of lessons, teacher journal entries, student artefacts, questionnaire results and interviews. It was found that there were positive effects for Wayne's learning using this approach including improved behaviour, greater feelings of self‐efficacy, increased participation in small group and class discussions and improved outcomes on the same assessment tasks as peers. It is suggested that the structured approach of the TFA, the communication of understanding in different modalities, particularly drawing, and the support of peers enabled Wayne to more deeply engage in construction of understanding and may provide teachers with an easy and effective approach to authentic inclusion where real conceptual gains are made by all students.  相似文献

This article presents a qualitative study concerning student teachers’ understanding of differentiation for high-achieving secondary school students with higher learning potential. Predominantly using focus group interviews of Norwegian student teachers (N = 322), this study identified their understanding of the use and value of differentiation, drawing from their teaching practice and experience. This study supports the notion that student teachers lack confidence in enacting differentiation, despite being aware of its importance, when working with these students. We contend that teacher education needs to pay more attention to helping student teachers effectively differentiate to meet the needs of high-achieving students with higher learning potential.  相似文献

This paper describes a project on electricity education, aiming at the construction of a teaching strategy which takes into account pupils’ alternative conceptions on electric circuits. With this project we want to provide teachers with feasible diagnostic tools and teaching materials in order to promote conceptual change among pupils. The research findings indicate the effectiveness of a teaching strategy in one of the higher forms of secondary education in which an explicit confrontation takes place between the pupils’ own alternative conceptions and some physics concepts in the domain of electricity.  相似文献

Research indicates that teachers’ conceptions of and approaches to teaching with technology are central for the successful imple-mentation of educational technologies in higher education. This study advances this premise. We present a 10-year longitudinal study examining teachers’ conceptions of and approaches to teaching and learning with technology. Nine teachers on an online Bachelor of Science in Pharmacy and a Master of Pharmacy programme at a Swedish university were studied using a phenomenographic approach. Results showed clear differences between novice and experienced teachers. Although novice teachers initially held more teacher-focused conceptions, they demonstrated greater and more rapid change than experienced colleagues. Experienced teachers tended to exhibit little to no change in conceptions. Supporting conceptual change should, therefore, be a central component of professional development activities if a more effective use of educational technology is to be achieved.  相似文献
