In the first part of this paper, studies are reviewed which suggest that gender differences in science achievement can be explained entirely in terms of social factors, and which also suggest that these differences could be eliminated, or even reversed, by changing the social environment. For the studies examined, it is suggested that research workers may not have taken sufficient account of confounding variables in their work, and that the apparent changes in gender differential reported may be explained in terms of these confounding variables.

In the second part of the paper, studies are reviewed which seek explanation of gender differences in science achievement in terms of unequal treatment of boys and girls by science teachers in the classroom. It is concluded that the quality of the research work which has been undertaken is disappointing, and that the research evidence provided by these studies for the differential treatment of boys and girls by science teachers is far from convincing.

It is concluded that real gender differences in science achievement do exist, and that they cannot be explained fully in terms of the social environment. It is suggested that both biological and sociological theoretical perspectives on gender differences in science achievement are inadequate, and that further progress in understanding gender differences in science achievement will require a new theoretical synthesis. It is suggested that sociobiology may provide the required new theoretical synthesis by allowing for the recognition of both biological and environmental influences on science achievement.  相似文献

In this exploratory case study, we sought to understand teacher's integration of multicultural curricula in science curriculum units, and how personal experiences influenced the level of integration in light of Bank's typology of ethnic content integration into school curricula. Five research participants volunteered and were selected so as to be representative of the demographic of pre‐service and in‐service teachers in the southern United States. The aim was to explore teachers' personal experiences with cultural others that either facilitated or impeded their adoption of multicultural curricula strategies in science curricula units. Case narratives present and discuss interview data and assigned curricula projects. Findings suggest that participants who had transformative cultural experiences and who identified as the marginalized cultural other, transformed science curricula at higher levels of Bank's typology for curricula' multicultural approaches. © 2012 Wiley Periodicals, Inc.

Internet‐based science learning has been advocated by many science educators for more than a decade. This review examines relevant research on this topic. Sixty‐five papers are included in the review. The review consists of the following two major categories: (1) the role of demographics and learners' characteristics in Internet‐based science learning, such as demographic background, prior knowledge, and self‐efficacy; and (2) the learning outcomes derived from Internet‐based science learning, such as attitude, motivation, conceptual understanding, and conceptual change. Some important conclusions are drawn from the review. For example, Internet‐based science learning is equally favorable, or in some cases more so, to learning for female students compared to male students. The learner's control is essential for enhancing students' attitudes and motivation toward learning in Internet‐based science learning environments. Nevertheless, appropriate guidance from teachers, moderators, or the Internet‐based learning environment itself is still quite crucial in Internet‐based science learning. Recommendations for future research related to the effects of Internet‐based science learning on students' metacognitive reflections, epistemological development, and worldviews are suggested.  相似文献

A great deal of research has been done regarding science in-service education and the conclusion can be drawn that positive results were generally achieved in workshop-participant attitude and implementation of instructional approaches into the classroom. One of the most important effects of an in-service workshop is upon the students of the teachers participating in an in-service program, but rarely, if ever, is this parameter assessed in the in-service evaluation design. This study investigated the relationships among (1) teacher's attitudes and implementation of in-service workshop developed science materials (learning cycles) and (2) elementary school student's conservation reasoning and language used to describe properties of objects. Data were gathered from over 100 students from grades K-5 and 16 teachers who had participated in an in-service program. A representative comparison group of students and teachers was selected which generally matched the teachers participating in the in-service workshop except for one variable–-the comparison group taught science traditionally, that is, by exposition. Data from the research indicated that the teachers involved in the science in-service workshop implemented the workshop-developed learning cycles into their science classes. Significantly greater gains in conservation reasoning and language usage occurred with the students of the teachers participating in the science in-service workshop as compared to students in the exposition classrooms.  相似文献

The pace of change in today's society means that there is an ongoing need for teachers to learn, have new knowledge and use new pedagogical approaches to meet the needs of their pupils. For many teachers, this requires redefining their identity as teachers and what ‘teaching’ means in 21st century learning environments. These changes also require teachers to be supported in learning to ‘teach’ in different ways that are relevant to their own individual needs and to the contexts in which they work throughout their career. In this article, it is argued that a more integrated and collaborative approach to teacher education is needed with better understanding of those who take up the roles of teacher educator across a teacher's career. With a particular emphasis on ‘teacher educators’ working in school to support teachers' career-long professional learning it is argued that currently many do not recognise themselves as teacher educators nor are they recognised by those they work with as teacher educators. Drawing on an empirical study carried out with mentors in schools in Scotland, it is suggested that these teacher educators may be ‘unrecognised’ and remain ‘hidden professionals’ because of the identities they construct for themselves, the values and priorities that they or others attach to their roles or because of the institutional structures and cultures in which they work. It is concluded that it will be difficult to recognise and value these ‘hidden teacher educators’ and the distinctive contribution they can make to teachers' career-long professional learning without further clarification by them and others of the roles and responsibilities they hold.  相似文献

Part of the work of teaching elementary science involves evaluating elementary students' work. Depending on the nature of the student work, this task can be straightforward. However, evaluating elementary students' representations of their science learning in the form of scientific models can pose significant challenges for elementary teachers. To address some of these challenges, we incorporated a modeling-based elementary science unit in our elementary science teaching methods course to support preservice teachers in gaining knowledge about and experience in evaluating students' scientific models. In this study, we investigate the approaches and criteria preservice elementary teachers use to evaluate elementary student-generated scientific models. Our findings suggest that with instruction, preservice elementary teachers can adopt criterion-based approaches to evaluating students' scientific models. Additionally, preservice teachers make gains in their self-efficacy for evaluating elementary students' scientific models. Taken together, these findings indicate that preservice teachers can begin to develop aspects of pedagogical content knowledge for scientific modeling.  相似文献

The development of three-dimensional learning among all K-12 student demographics remains a prominent goal for the field of science education. However, substantial research in science teacher education for urban populations showcases hurdles to overcome in order to achieve this goal, particularly for elementary teachers. Research shows that urban elementary teachers are often ill-prepared to develop a type of science pedagogy responsive to students' learning needs. The fidelity of such pedagogies that these teachers adhere to when trying to implement such a requested content–relationality between these populations and how their local contexts can be used as sites to learn science in relevant ways are often not fully realized, as well. Given that science achievement gaps exhibit racial disparities starting in primary grades and attitudes toward science have been shown to affect academic achievement and motivation, we argue that one way to ameliorate, in at least an incremental way, this disparity is to design novel learning experiences to prime students to see the relevancy of science in their local contexts before such three-dimensional designed learning is set to occur. In this research, we leveraged the immersive nature of Virtual Reality 360 videos and present a design-based research iteration testing how this novel technologically enhanced learning experience may have influenced close to 400 urban elementary students' attitudes toward science around those attitudes labeled as “behavioral beliefs” by the field. Using a concurrent, convergent mixed-methods design with a two-way multivariate analysis of covariance quantitative data set triangulated with students' qualitative self-reports that were transformed into quantitative preponderances in graphic form, the data support that our design iteration emphasizing the importance of context as a design focus can prime students who struggle to see science as relevant to change their attitudes. Implications are discussed around relationality, novel technological affordances, and the use of local contexts as learning resources.  相似文献

The growing tendency away from transmissive pedagogy to a broadly constructivist pedagogy in higher education is characterised as a cultural change which lacks a strong theoretical foundation within the culture. In this paper, learning is considered from a phenomenographic perspective, which teachers can ground in their own experience of teaching and work with to gain insights into their students' experience of learning. Thereby the theoretical foundation of the culture can successively be strengthened. The message is illustrated with the results of empirical research into students' experience of learning in groups in a project-focused induction course to a computer science and engineering programme.  相似文献

This investigation examined 10th‐grade biology students' decisions to enroll in elective science courses, and explored certain attitudinal perceptions of students that may be related to such decisions. The student science perceptions were focused on student and classroom attitudes in the context of differing learning cycle classrooms (high paradigmatic/high inquiry, and low paradigmatic/low inquiry). The study also examined possible differences in enrollment decisions/intentions and attitudinal perceptions among males and females in these course contexts. The specific purposes were to: (a) explore possible differences in students' decisions, and in male and female students' decisions to enroll in elective science courses in high versus low paradigmatic learning cycle classrooms; (b) describe patterns and examine possible differences in male and female students' attitudinal perceptions of science in the two course contexts; (c) investigate possible differences in students' science perceptions according to their decisions to enroll in elective science courses, participation in high versus low paradigmatic learning cycle classrooms, and the interaction between these two variables; and (d) examine students' explanations of their decisions to enroll or not enroll in elective science courses. Questionnaire and observation data were collected from 119 students in the classrooms of six learning cycle biology teachers. Results indicated that in classrooms where teachers most closely adhered to the ideal learning cycle, students had more positive attitudes than those in classrooms where teachers deviated from the ideal model. Significantly more females in high paradigmatic learning cycle classrooms planned to continue taking science course work compared with females in low paradigmatic learning cycle classrooms. Male students in low paradigmatic learning cycle classrooms had more negative perceptions of science compared with males in high paradigmatic classrooms, and in some cases, with all female students. It appears that using the model as it was originally designed may lead to more positive attitudes and persistence in science among students. Implications include the need for science educators to help teachers gain more thorough understanding of the learning cycle and its theoretical underpinnings so they may better implement this procedure in classroom teaching. © 2001 John Wiley & Sons, Inc.

Scotland's rich heritage in the field of science and engineering and recent curricular developments led to major investment in education to equip pupils with improved scientific knowledge and skills. However, due to its abstract and conceptual nature, learning science can be challenging. Literature supports the role of multimedia technology in addressing the difficulties associated with science learning. This paper reports on a two‐phase investigation that explored the impact of multimedia resources situated in a national e‐learning portal to (1) assist generalist and specialist science teachers' teaching practices and (2) stimulate pupils' interest, encourage engagement and improve overall science learning experiences. Our research also investigated how portal resources facilitated and/or acted as barriers for teaching and learning. Findings from our research affirm that multimedia technology has transformed science learning; with these resources accessible through a national portal, radically different learning experiences ensued. These findings raise serious implications for teacher education and professional development in ensuring that teachers acquire sound science content and pedagogical knowledge as well as practical strategies for utilising technology‐rich environments, as this is likely to become the norm. Harnessing the fullest potential that information and communication technology, multimedia and e‐learning portals can offer starts by addressing these challenges.  相似文献

A key step in helping students to achieve scientific literacy is to ensure that each school's curriculum supports students' efforts to learn science meaningfully. Educational researchers play a vital role in this step by providing teachers, teacher educators, administrators, and policy makers with information about the creation of a curriculum that supports scientific literacy. In a scientific literacy curriculum, reading and writing can serve as dynamic vehicles for learning science meaningfully. The task of educational researchers is to show how reading and writing can be used most effectively to support science learning. Much of what is done now in schools is based on teacher intuition—good intuition—but intuition nonetheless. What is needed is school-based research to validate and build upon these intuitions. This article is intended to stimulate research on reading and writing to learn science.  相似文献

Science education in the United Kingdom faces a dual challenge in the near future: that of addressing increasing disaffection from the subject by pupils as they enter adolescence coupled with the downturn in learning as they leave primary school behind. Both bridging work and teacher creativity have been identified as key ingredients in ensuring pupil engagement in learning, yet innovation requires both time and a broader vision than may be offered by a normative and centralized pedagogy. This paper proposes a four‐stage model for curriculum development to encourage creativity, based on the experiences of teachers as they designed bridging work for pupils in science. A grounded theory approach is utilized to generate four concept categories emerging from participants' comments during the study. These are described as uncertainty, visioning, realization and readiness, and this research demonstrates that ‘bottom–up’ is a very effective method of professional development promoting combinatorial thinking and creative science teaching.  相似文献

This research explored the practices of one science teacher, expert in her field, as she worked to enact science discourse that incorporated language in naturalistic and rigorous ways. Difficulties in mastering the language of science contribute to troubling and persistent achievement gaps across demographic and gender groups. Science learning is based in discourse, with knowledge built by asking questions, exploring, revising views and asking new questions. But all too often students are not able to participate fully in these opportunities for discourse that is engaging and exploration due to the difficulty of science language. Qualitative analysis of this teacher's use of science discourse to establish clear links between essential science language and concepts and pre/post analysis of a science language assessment reveal important ways that teachers and researchers can work together to design and deliver instruction and assessment that supports students' mastery of sophisticated language and concepts. Results have implications for theory regarding science discourse; language learning, and conceptual development; and provide a model for teacher–researcher partnerships exploring important problems of teaching practice.  相似文献

Previous research indicates that supportive school leadership is a key condition of collaborative teacher learning. The purpose of this study was to develop a typology of how school leaders foster collaborative teacher learning. We adopted an integrative perspective on leadership by examining both learning-centred leadership and distributed leadership practices that are supportive of collaborative teacher learning. Data were gathered by means of interviews with ten school leaders and a questionnaire that was completed by 39 teachers from six secondary schools in the Netherlands. The aim of the interviews was to identify to what extent school leaders applied learning-centred leadership and distributed leadership practices. The questionnaire measured teachers' perceptions of the role of school leaders in teacher learning. As an outcome of this study, we constructed a typology that provides insights into how school leaders foster collaborative teacher learning. Four types of school leaders were distinguished: (a) integrators of teacher learning, (b) facilitators of teacher learning, (c) managers of teacher learning, and (d) managers of daily school practice. Our findings suggest that integration of learning-centred leadership and distributed leadership practices can help school leaders to support collaborative teacher learning.  相似文献

Developing pre-service science teachers’ epistemic insight remains a challenge, despite decades of research in related bodies of work such as the nature of science (NOS) in science education. While there may be numerous aspects to this problem, one critical element is that the NOS is a meta-concept that demands higher-order cognitive skills. One possible strategy to facilitate pre-service teachers’ understanding of epistemic aspects of science is visualisation. Visual representations of objects and processes can be tools for developing and monitoring understanding. Although the NOS and visualisation literatures have been studied extensively, the intersection of these bodies of literatures has been minimal. Incorporating visual tools on the NOS in teacher education is likely to facilitate teachers’ learning, eventually impacting their students’ learning of the NOS. The objective of this paper is to illustrate how the visual tools of scientific knowledge and practices aspects of the NOS can be integrated in science teacher education in order to develop pre-service teachers’ epistemic insight. The paper presents an empirical study that incorporated visual tools about the NOS in primary science teacher education. Data on 14 pre-service teachers’ are presented along with in-depth case studies of 3 pre-service teachers illustrating the influence of the teacher education intervention. The qualitative analysis of visual representations before and after the intervention as well as verbal data suggests that there was improvement in pre-service teachers’ perceptions of the NOS. Implications for future research on visualisation of the NOS are discussed.  相似文献

The main purpose of this study was to concurrently investigate Taiwanese high-school students' and their science teachers' conceptions of learning science (COLS) and conceptions of science assessment (COSA). A total of 1,048 Taiwanese high-school students and their 59 science teachers were invited to fill out two questionnaires assessing their COSA and COLS. The main results indicated that, first, although a handful of different patterns occurred, students and teachers were found to have similar COLS–COSA patterns. In general, students and teachers with COSA as reproducing knowledge and rehearsing tended to possess lower-level COLS, such as learning science as memorizing, testing, and calculating and practicing. In contrast, if students and teachers viewed science assessment as improving learning and problem-solving, they would be prone to regard science learning as increase of knowledge, applying, and understanding and seeing in a new way. However, the students' conceptions did not align with those of the teachers' in certain aspects. The students tended to regard science learning and assessment at a superficial level (COLS as ‘memorizing’, ‘testing’, and ‘calculating and practicing’ and COSA as ‘reproducing knowledge’), while the teachers’ conceptions were at a more sophisticated level (COLS as ‘application’ and ‘understanding and seeing in a new way’ and COSA as ‘improving learning’). It is evident that a dissonance exists between the students' and teachers' COLS and COSA. Based on the results, practical implications and suggestions for future research are discussed.  相似文献

The purpose of this ethnographic study was to explore the development of belief systems as related to racial and ethnic identities of preservice teachers as they crossed cultural borders into science teaching. Data were collected throughout a yearlong teacher preparation program to learn how early life experiences and racial and ethnic identities of preservice teachers influenced both their beliefs about diversity in science classrooms and science teaching pedagogy. Case studies of three preservice teachers from diverse racial and ethnic background are presented: Asian American, African American, and Rural Appalachian. Using Bank's ethnicity typology, findings suggest that racial and ethnic identity, developed in early life experiences of preservice teachers, provided clarity on the rigidity of their beliefs about diversity and how they view science teaching. By learning about the border crossing experiences of preservice teachers in relation to their beliefs about diversity as related to racial and ethnic identities, the researchers hoped to provide insight on preparing preservice teachers for the challenges of working in diverse classrooms. © 2004 Wiley Periodicals, Inc.

We explored the use of the learning study (LS) model in developing Swedish pre-school science learning. This was done by analysing a 3-cycle LS project implemented to help a group of pre-school teachers (n?=?5) understand their science educational practice, by collaboratively and systematically challenging it. Data consisted of video recordings of 1 screening (n?=?7), 1 initial planning meeting, 3 analysis meetings, 3 interventions, and 78 individual test interviews with the children (n?=?26). The study demonstrated that the teachers were initially uncomfortable with using scientific concepts and with maintaining the children's focus on the object of learning without framing it with play. During the project, we noted a shift in focus towards the object of learning and how to get the children to discern it. As teachers’ awareness changed, enhanced learning was noted among the children. The study suggests that the LS model can promote pre-school science learning as follows: by building on, re-evaluating, and expanding children's experiences; and by helping the teachers focus on and contrast critical aspects of an object of learning, and to reflect on the use of play, imagination, and concepts and on directing the children's focus when doing so. Our research showed that the LS model holds promise to advance pre-school science learning by offering a theoretical tool useable to shift the focus from doing to learning while teaching science using learning activities.  相似文献

An important contribution to effective teaching and learning can be made by teachers' understanding of the central topics in each subject area and knowing how to transform their content knowledge into knowledge for teaching. One aspect of this knowledge is the use of analogies which can effectively communicate concepts to students of particular backgrounds and prerequisite knowledge. Indeed, analogies are considered to be an important component in the repertoire of effective teachers. However, research about teachers' use of analogies in science lessons provides little guidance about the optimum approaches that may be taken by preservice teachers, novice teachers, experienced teachers or reluctant analogy users. This paper describes the evolution of an approach for using analogies in science teaching that addresses both findings from the research literature and recognises the needs of practising teachers. Specializations: learning and teaching science concepts, technology education.  相似文献
