Resistance to more humanistic forms of science education is an endemic and persistent feature of university scientists as well as school science teachers. This article argues that science education researchers should pay more attention to its origins and to the subtleties of its stubborn influence. The paper explores some of the imperatives which dominate the continuing practices of teachers; the linkages between school and university science; and re-considers the relationships between learning science, learning to do science and learning about science. It draws on recent, prominent publications, as well as neglected and rather more contentious material, to underline the unhelpfully narrow view of science held by those who defend the traditional disciplinary influences of biology, chemistry and physics. Suggestions are made as to where those of a more radical and determined disposition should direct their attention in the interests of improved education, vital scientific progress as well as human survival. It is argued that university science must change in order to ensure that teachers better help their students to learn, do and appreciate science.  相似文献

This paper describes the methods and outcomes of a 12-year longitudinal study into the effects of an early intervention program, while reflecting back on changes that have occurred in approaches to research, learning and instruction since the preliminary inception stages of the study in the mid 1960s. We began the study to challenge the prevailing consensus at the time that primary school children were either preoperational or concrete operational in their cognitive development and they could not learn abstract concepts. Our early research, based on Ausubelian theory, suggested otherwise. The paper describes the development and implementation of a Grade 1–2 audio tutorial science instructional sequence, and the subsequent tracing over 12 years, of the children’s conceptual understandings in science compared to a matched control group. During the study the concept map was developed as a new tool to trace children’s conceptual development. We found that students in the instruction group far outperformed their non-instructed counterparts, and this difference increased as they progressed through middle and high school. The data clearly support the earlier introduction of science instruction on basic science concepts, such as the particulate nature of matter, energy and energy transformations. The data suggest that national curriculum standards for science grossly underestimate the learning capabilities of primary-grade children. The study has helped to lay a foundation for guided instruction using computers and concept mapping that may help both teachers and students become more proficient in understanding science.  相似文献

Research Findings: This paper reports on children's use of science materials in preschool classrooms during their free choice time. Baseline observations showed that children and teachers rarely spend time in the designated science area. An intervention was designed to “market” the science center by introducing children to 1 science tool, the balance scale. Baseline measures showed that children did not know the scale's name or function. The intervention was expected to increase children's use of the science area and their knowledge about the scale. Children's voluntary presence and exploration in the science area increased after the balance scale intervention compared to in comparison classrooms. Furthermore, children who participated in this intervention demonstrated improved knowledge about the scale's function, whereas students in the comparison group did not. Practice or Policy: Adults can increase children's autonomous exploration of science tools and materials, and their knowledge about them, by offering particular kinds of large-group learning experiences.  相似文献

The purpose of this paper is to describe how and why a primary science methods classroom was conceived, designed, and developed for preservice and inservice teachers. Just as science educators believe that students learn best by constructing their knowledge of the natural world with the aid of a teacher and colleagues, science educators also believe that preservice and inservice teachers should learn in a collaborative and constructivist environment. Multiple dimensions relating to the dynamic processes of learning to teach, a ‘technical factor’ related to the physical and resource constraints that exist within a school, and sociocultural theory were used for the theoretical framework. A survey was given to 97 students who took a course in the classroom, six instructors were given a questionnaire, and three of these instructors were interviewed. These data sources sought to determine the effect of design features on student learning and instructor teaching. The results of the evaluation suggest students who used the classroom found their learning positively affected by the room design and instructors who taught in the classroom benefited by being able to teach in an inquiry and constructivist manner.  相似文献

Context-based chemistry education aims to improve student interest and motivation in chemistry by connecting canonical chemistry concepts with real-world contexts. Implementation of context-based chemistry programmes began 20 years ago in an attempt to make the learning of chemistry meaningful for students. This paper reviews such programmes through empirical studies on six international courses, ChemCom (USA), Salters (UK), Industrial Science (Israel), Chemie im Kontext (Germany), Chemistry in Practice (The Netherlands) and PLON (The Netherlands). These studies are categorised through emergent characteristics of: relevance, interest/attitudes/motivation and deeper understanding. These characteristics can be found to an extent in a number of other curricular initiatives, such as science-technology-society approaches and problem-based learning or project-based science, the latter of which often incorporates an inquiry-based approach to science education. These initiatives in science education are also considered with a focus on the characteristics of these approaches that are emphasised in context-based education. While such curricular studies provide a starting point for discussing context-based approaches in chemistry, to advance our understanding of how students connect canonical science concepts with the real-world context, a new theoretical framework is required. A dialectical sociocultural framework originating in the work of Vygotsky is used as a referent for analysing the complex human interactions that occur in context-based classrooms, providing teachers with recent information about the pedagogical structures and resources that afford students the agency to learn.  相似文献

During their years of schooling, students develop perceptions about learning and teaching, including the ways in which teachers impact on their learning experiences. This paper presents student perceptions of teacher pedagogy as interpreted from a study focusing on students' experience of Year 7 science. A single science class of 11 to 12 year old students and their teacher were monitored for the whole school year, employing participant observation, and interviews with focus groups of students, their teacher and other key members of the school. Analysis focused on how students perceived the role of the teacher's pedagogy in constructing a learning environment that they considered conducive to engagement with science learning. Two areas of the teacher's pedagogy are explored from the student perspective of how these affect their learning: instructional pedagogy and relational pedagogy. Instructional pedagogy captures the way the instructional dialogue developed by the teacher drew the students into the learning process and enabled them to “understand” science. How the teacher developed a relationship with the students is captured as relational pedagogy, where students said that they learned better when teachers were passionate in their approach to teaching, provided a supportive learning environment and made them feel comfortable. The ways in which the findings support the direction for the middle years and science education are considered.  相似文献

This article reports on analyses of the instructional practices of six middle- and high-school science teachers in the United States who participated in a research-practice partnership that aims to support reform science education goals at scale. All six teachers were well qualified, experienced, and locally successful—respected by students, parents, colleagues, and administrators—but they differed in their success in supporting students' three-dimensional learning. Our goal is to understand how the teachers' instructional practices contributed to their similarities in achieving local success and to differences in enabling students' learning, and to consider the implications of these findings for research-practice partnerships. Data sources included classroom videos supplemented by interviews with teachers and focus students and examples of student work. We also compared students' learning gains by teacher using pre–post assessments that elicited three-dimensional performances. Analyses of classroom videos showed how all six teachers achieved local success—they led effectively managed classrooms, covered the curriculum by teaching almost all unit activities, and assessed students' work in fair and efficient ways. There were important differences, however, in how teachers engaged students in science practices. Teachers in classrooms where students achieved lower learning gains followed a pattern of practice we describe as activity-based teaching, in which students completed investigations and hands-on activities with few opportunities for sensemaking discussions or three-dimensional science performances. Teachers whose students achieved higher learning gains combined the social stability characteristic of local classroom success with more demanding instructional practices associated with scientific sensemaking and cognitive apprenticeship. We conclude with a discussion of implications for research-practice partnerships, highlighting how partnerships need to support all teachers in achieving both local and standards-based success.  相似文献

Background: Photovoice is one method that enables an educator to view an experience from a student’s perspective. This study examined how teachers might use photovoice during an informal learning experience to understand the students’ experiences and experiential gain.

Design and methods: Participants in this study consisted of six students, three male and three female, ranging from ninth through twelfth grade at a rural Ohio high school, who attended a field trip to a biological field station for a four-day immersive science experience. Students were provided cameras to photograph what they believed was important, interesting, or significant during an immersive four-day science trip to a biological field station, individualizing their observations in ways meaningful to them, and enabling them to assimilate or accommodate the experiences to their schema.

Results: Analysis identified five positive benefits to use photovoice as an evaluation tool: teachers were provided qualitative evidence to evaluate student interaction on the field trip; teachers could evaluate the students’ photographs and captions to determine if the field trip met the learning objectives; students were empowered to approach the goals and objectives of the field trip by making the field trip personally relevant; students assimilated and accommodated the new observations and experiences to their own schema; students automatically reflected upon the learning experience as they captioned the photos.

Conclusions: Through photovoice, the teachers were enabled to qualitatively assess each student’s experience and learning from the field trip by illustrating what the students experienced and thought was significant; providing the teachers a method to evaluate all participating students, including those who are secretive or do not normally contribute to class discussions.  相似文献

Computer scoring of student written essays about an inquiry topic can be used to diagnose student progress both to alert teachers to struggling students and to generate automated guidance. We identify promising ways for teachers to add value to automated guidance to improve student learning. Three teachers from two schools and their 386 students participated. We draw on evidence from student progress, observations of how teachers interact with students, and reactions of teachers. The findings suggest that alerts for teachers prompted rich teacher–student conversations about energy in photosynthesis. In one school, the combination of the automated guidance plus teacher guidance was more effective for student science learning than two rounds of personalized, automated guidance. In the other school, both approaches resulted in equal learning gains. These findings suggest optimal combinations of automated guidance and teacher guidance to support students to revise explanations during inquiry and build integrated understanding of science.  相似文献

This study examined early childhood educators' perceptions about nature, science, and environmental education. Preservice early childhood teachers (n = 195) and early childhood professionals currently practicing in the field (n = 162) rated the importance of providing specific nature/science experiences for young children, the importance of specific nature/science learning outcomes, and their confidence implementing specific activities. Research Findings: Consistent with our hypotheses, both professionals and students rated the curricular domain of nature/science as the least important for young children in terms of experiences and learning outcomes in comparison to other curricular domains. Similarly, both professionals and students reported that they were least confident implementing nature/science activities compared to activities in other curricular domains. Qualitative analysis of open-ended questions yielded themes related to definitions of nature, specific activities in and about nature that can promote children's learning and development, and what educators need to know and be able to do in order to be effective “nature educators.” Practice or Policy: Preservice and in-service teacher professional development would benefit from (a) the inclusion of content on nature, science, and environmental education, including the interrelatedness of human and natural systems; (b) a focus on place-based education and/or emergent curriculum; and (c) the provision of experiences in nature that help teachers to develop confidence implementing activities in nature.

This paper describes a professional development program using an interactive multimedia program to develop teachers' understanding of a constructivist epistemology in science education. The aim of this study was to describe teachers' reflections on and perceptions of a series of professional development workshops and how teachers changed their classroom practices after having participated in the workshops. The software, developed with the cooperation of teachers and students, is based on the Birds of Antarctica database (Maor & Phillips, 1996). This database was designed as an interactive program which requires teachers to use a constructivist-oriented approach to teaching and learning in order to promote the development of inquiry skills particularly higher-order thinking skills. A series of workshops for teachers was conducted to empower them to become comfortable with using computers in science classrooms and to enable them to enhance their understanding of, and ability to use, personal and social constructivist approaches. Teachers' perceptions of the process of learning with the multimedia program and their reactions to their experiences were assessed using a new instrument, the Constructivist Multimedia Learning Environment Survey (CMLES). The results of the study suggest that teachers who participated as learners in the professional development program became familiar with a constructivist-oriented multimedia learning environment; understood the context, problems, and issues faced by students in the classroom; and were better able to facilitate students' needs and understanding in this learning environment. This revised version was published online in July 2006 with corrections to the Cover Date.  相似文献

While there is a growing literature focused on doctoral preparation for teaching about science teaching, rarely have recommendations extended to preparation for teaching science content to teachers. We three doctoral students employ self-study as a research methodology to investigate our developing pedagogical content knowledge for teaching science to teachers during a mentored internship in an elementary teacher professional development program. With our mentor, we examine critical incidents in the experience that supported new insights about teaching teachers and about ways in which beginning teacher educators need to develop their existing pedagogical content knowledge for teaching science to students in order to teach science effectively to teachers. We emphasize ways in which doctoral internships can support this learning and how our respective cultures shaped our interactions with and perceptions of teachers as learners.  相似文献

Background: Problem-based learning (PBL) is a teaching approach working in cooperation with self-learning and involving research to solve real problems. The first law of thermodynamics states that energy can neither be created nor destroyed, but that energy is conserved. Students had difficulty learning or misconceptions about this law. This study is related to the teaching of the first law of thermodynamics within a PBL environment.

Purpose: This study examined the effectiveness of PBL on candidate science teachers’ understanding of the first law of thermodynamics and their science process skills. This study also examined their opinions about PBL.

Sample: The sample consists of 48 third-grade university students from the Department of Science Education in one of the public universities in Turkey.

Design and methods: A one-group pretest–posttest experimental design was used. Data collection tools included the Achievement Test, Science Process Skill Test, Constructivist Learning Environment Survey and an interview with open-ended questions. Paired samples t-test was conducted to examine differences in pre/post tests.

Results: The PBL approach has a positive effect on the students’ learning abilities and science process skills. The students thought that the PBL environment supports effective and permanent learning, and self-learning planning skills. On the other hand, some students think that the limited time and unfamiliarity of the approach impede learning.

Conclusions: The PBL is an active learning approach supporting students in the process of learning. But there are still many practical disadvantages that could reduce the effectiveness of the PBL. To prevent the alienation of the students, simple PBL activities should be applied from the primary school level. In order to overcome time limitations, education researchers should examine short-term and effective PBL activities.  相似文献

Background: In Bangladesh, a common science curriculum caters for all students at the junior secondary level. Since this curriculum is for all students, its aims are both to build a strong foundation in science while still providing students with the opportunities to use science in everyday life – an aim consistent with the notion of scientific literacy.

Purpose: This paper reports Bangladeshi science teachers’ perspectives and practices in regard to the promotion of scientific literacy.

Sample: Six science teachers representing a range of geographical locations, school types with different class sizes, lengths of teaching experience and educational qualifications.

Design and method: This study employed a case study approach. The six teachers and their associated science classes (including students) were considered as six cases. Data were gathered through observing the teachers’ science lessons, interviewing them twice – once before and once after the lesson observation, and interviewing their students in focus groups.

Results: This study reveals that participating teachers held a range of perspectives on scientific literacy, including some naïve perspectives. In addition, their perspectives were often not seen to be realised in the classroom as for teachers the emphasis of learning science was more traditional in nature. Many of their teaching practices promoted a culture of academic science that resulted in students’ difficulty in finding connections between the science they study in school and their everyday lives. This research also identified the tension which teachers encountered between their religious values and science values while they were teaching science in a culture with a religious tradition.

Conclusions: The professional development practice for science teachers in Bangladesh with its emphasis on developing science content knowledge may limit the scope for promoting the concepts of scientific literacy. Opportunities for developing pedagogic knowledge is also limited and consequently impacts on teachers’ ability to develop the concepts of scientific literacy and learn how to teach for its promotion.  相似文献

This study examines the impact of Disaggregate Instruction on students’ science learning. Disaggregate Instruction is the idea that science teaching and learning can be separated into conceptual and discursive components. Using randomly assigned experimental and control groups, 49 fifth‐grade students received web‐based science lessons on photosynthesis using our experimental approach. We supplemented quantitative statistical comparisons of students’ performance on pre‐ and post‐test questions (multiple choice and short answer) with a qualitative analysis of students’ post‐test interviews. The results revealed that students in the experimental group outscored their control group counterparts across all measures. In addition, students taught using the experimental method demonstrated an improved ability to write using scientific language as well as an improved ability to provide oral explanations using scientific language. This study has important implications for how science educators can prepare teachers to teach diverse student populations.  相似文献

This study examines individual and classroom-level differences in motivation and strategy usage in sixth- and seventh-grade middle school science. Results suggest that students who experience academic difficulties differ from both high achieving and special education students on measures of self-efficacy, goal orientation, expectancy, value, and self-concept of ability in science, with students who experience academic difficulties occasionally demonstrating less adaptive patterns of motivation and cognition than special education students in science. We used hierarchical linear modeling to examine between-classroom differences in learning-focused goal orientation. Findings indicate that students who have science teachers that use ability-focused instructional practices (e.g., pointing out the best students as an example to others) are less learning focused, and exhibit a diminished relation between self-concept of ability and being learning focused in science. Implications for science education reform are discussed.  相似文献

This study demonstrates the power of the cultural encounter metaphor in explaining learning and teaching difficulties, using as an example computer science education (CSE). CSE is envisioned as an encounter between veterans of two computer-oriented cultures, that of the teachers and that of the students. Forty questionnaires administered to CS teachers, as well as in-depth interviews with four leading CS teachers, revealed those teachers perceived their students as having a different perspective on the domain, on what constitutes a beneficial approach to problem-solving and on the nature of satisfactory solutions. In fact, the teachers portrayed their teaching as a continual battle in which their success is limited. Yet, their instruction was characterized as a composite of enforcement and compromise, with few and isolated attempts at building on students’ cultural capital. The cultural encounter metaphor, while still viewing students as novices to the professional CS culture represented by their teachers, emphasizes that good teaching requires building upon students’ cultural capital to create zones of fertile cultural encounter.  相似文献

With the globalisation of education, large numbers of students with interrupted schooling and low English literacy levels represent both a quantitative and qualitative shift in the kinds of students faced by teachers in classrooms. In Australia, after a year in an intensive English language programme, immigrant and refugee students are placed in the mainstream, where they face enormous challenges in content areas such as science. The complexity and specificity of science terminology pose a serious barrier for students. This article reports on a research project to support vocabulary learning in mainstream science for Year 8 refugee students (n = 23) in one high school. Data sources included teacher interviews, student journal writing, and the science text itself. The author demonstrates why science content language is inaccessible to many students through an extensive review of the literature, and then juxtaposes the views of students and teachers with the actual demands of one chapter from the Year 8 Science textbook on states of matter. The final section presents the response of the researchers to help scaffold vocabulary learning for this topic and a trial of the materials. The study highlights the links between conceptual and linguistic understanding. Given that students identified vocabulary as a major barrier to learning, and that the science teacher tended to assume rather than to explain new terminology, the language‐focused approach outlined to support vocabulary was seen as one way to address an urgent problem. Implications for professional development and teacher education are also addressed.  相似文献
