The challenge of preparing students for the information age has prompted administrators to increase technology in the public schools. Yet despite the increased availability of technology in schools, few teachers are integrating technology for instructional purposes. Preservice teachers must be equipped with adequate content knowledge of technology to create an advantageous learning experience in science classrooms. To understand preservice teachers’ conceptions of technology integration, this research study explored 15 elementary science methods students’ definitions of technology and their attitudes toward incorporating technology into their teaching. The phenomenological study took place in a science methods course that was based on a constructivist approach to teaching and learning science through science activities and class discussions, with an emphasis on a teacher beliefs framework. Data were collected throughout the semester, including an open-ended pre/post-technology integration survey, lesson plans, and reflections on activities conducted throughout the course. Through a qualitative analysis, we identified improvements in students’ technology definitions, increased technology incorporation into science lesson plans, and favorable attitudes toward technology integration in science teaching after instruction. This research project demonstrates that positive changes in beliefs and behaviors relating to technology integration in science instruction among preservice teachers are possible through explicit instruction.  相似文献

We investigated how prospective teachers used physics content knowledge when analyzing the talk of elementary children during special activities in an undergraduate physics content course designed for prospective teachers. We found that prospective teachers used content knowledge to reflect on their own learning and to identify students’ science ideas and restate these ideas in scientific terms. Based on this research, we inferred that analyzing children’s ideas through videos provides a meaningful context for applying conceptual physics knowledge in physics courses. Activities that are embedded within a disciplinary curriculum, such as those studied here, may help prospective teachers learn to use disciplinary knowledge in exactly the type of activity in which their content knowledge will be most useful: listening to and interpreting children’s science ideas.  相似文献

Using the National Research Council's inquiry continuum framework, we use a multiple-case study research design to investigate the teacher- and student-directedness of elementary preservice teachers’ planned and enacted science lessons and their pedagogical reasoning about science instruction during a semester-long science methods course. Our specific research questions were (1) What ideas do elementary preservice teachers bring to a science teaching methods course about the inquiry continuum? and (2) How do their ideas about the inquiry continuum change over the course of the semester through engaging in planning, enactment, and reflection upon science instruction? Participants’ course artifacts (journals, reflective teaching assignments, and lesson plan rationales), interviews, and field observations of their enacted science lessons served as data for this study. Findings show that although the preservice teachers began the semester defining inquiry as highly student-directed, their ideas and definitions broadened over the course of the semester to include and embrace more teacher-directed forms of inquiry. Their early science lessons were more student-directed but, as they encountered challenges engaging in inquiry-based instruction and increasingly emphasized students’ learning needs, they began to plan and enact lessons that were more teacher-directed. Teacher education programs need to explicitly emphasize these variations of inquiry as a core component of supporting preservice teachers’ learning to teach science as inquiry.  相似文献

Generations of students are graduating from secondary school disinterested in post-secondary study of science or pursuing careers in science-related fields beyond formal education. We propose that destabilising such disinterest among future students requires science educators to begin listening to secondary school students regarding their views of how science learning is made interesting within the science classroom. Studies on students’ interest in response to instructional strategies applied in the classroom communicate the opinions (i.e. the ‘voice’) of students about the strategies they believe make their classroom learning interesting. To this end, this scoping study (1) collects empirical studies that present from various science and non-science academic domains students’ views about how to make classroom learning interesting; (2) identifies common instructional strategies across these domains that make learning interesting; and (3) forwards an instructional framework called TEDI ([T]ransdisciplinary Connections; Mediated [E]ngagement; Meaningful [D]iscovery; and Self-determined [I]nquiry), which may provide secondary school science teachers with a practical instructional approach for making learning science genuinely interesting among their students within the secondary school science classroom context.  相似文献

The concept of matter, especially its particulate nature, is acknowledged as being one of the key concept areas in learning science. Within the framework of learning studies and variation theory, and with results from science education research as a starting point, six lower secondary school science teachers tried to enhance students’ learning by exploring what must be learnt in order to understand the concept in specific way. It was found that variation theory was a useful guiding principle when teachers are engaged in pedagogical design, analysis of lessons, and evaluation of students learning, as well as a valuable tool for adapting research results into practice.  相似文献

Employing achievement goal theory (Ames Journal of Educational psychology, 84(3), 261–271, 1992), we explored science teachers’ instruction and its relation to students’ motivation for science learning and school culture. Based on the TARGETS framework (Patrick et al. The Elementary School Journal, 102(1), 35–58, 2001) and using data from 95 teachers, we developed a self-report survey assessing science teachers’ usage of practices that emphasize mastery goals. We then used this survey and hierarchical linear modeling (HLM) analyses to study the relations between 35 science teachers’ mastery goals in each of the TARGETS dimensions, the decline in their grade-level 5–8 students’ (N = 1.356) classroom and continuing motivation for science learning, and their schools’ mastery goal structure. The findings suggest that adolescents’ declining motivation for science learning results in part from a decreasing emphasis on mastery goals by schools and science teachers. Practices that relate to the nature of tasks and to student autonomy emerged as most strongly associated with adolescents’ motivation and its decline with age.  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

This study explores five minority preservice teachers’ conceptions of teaching science and identifies the sources of their strategies for helping students learn science. Perspectives from the literature on conceptions of teaching science and on the role constructs used to describe and distinguish minority preservice teachers from their mainstream White peers served as the framework to identify minority preservice teachers’ instructional ideas, meanings, and actions for teaching science. Data included drawings, narratives, observations and self-review reports of microteaching, and interviews. A thematic analysis of data revealed that the minority preservice teachers’ conceptions of teaching science were a specific set of beliefs-driven instructional ideas about how science content is linked to home experiences, students’ ideas, hands-on activities, about how science teaching must include group work and not be based solely on textbooks, and about how learning science involves the concept of all students can learn science, and acknowledging and respecting students’ ideas about science. Implications for teacher educators include the need to establish supportive environments within methods courses for minority preservice teachers to express their K-12 experiences and acknowledge and examine how these experiences shape their conceptions of teaching science, and to recognize that minority preservice teachers’ conceptions of teaching science reveal the multiple ways through which they see and envision science instruction.  相似文献

Inquiry-based science instruction (IBSI) has the potential to contribute to social justice through widening participation and success in science. However, teachers struggle to implement IBSI because of contextual factors. The purpose of this paper is to explore the use of agency as a framework for understanding teachers’ decision-making, by asking the question: what was the agency of six science teachers in their social-justice aspirations and use of IBSI? An agency framework recognizes that teachers’ decisions are informed by their internal conversations at the intersection of personal aspects (their history, repertoire, and aspirations) with the cultural and structural constraints and resources of their contexts. However, research on IBSI has focussed on teachers’ personal aspects or their perceptions of contextual factors. The sample had learnt IBSI through service learning in the context of a science fair. From teacher interviews, it emerged that these teachers had strong social-justice aspirations to serve disadvantaged students. The teachers linked their social-justice aspirations to their choice of school rather than their use of IBSI. The teachers at better-resourced schools initiated participation in science fairs at their schools, whilst the rest judged that science fairs were not appropriate for their students. The results suggest that, rather than prescribing particular pedagogies, teacher education programmes should aim to increase teachers’ pedagogical repertoires, in order to enrich their agency in whatever contexts they teach.

Pedagogical content knowledge (PCK) is a type of teacher knowledge to be developed by a teacher. PCK is said to contribute to effective teaching. Most studies investigated the development of PCK and its influence on students’ learning from the teachers’ perspectives. Only a limited number of studies have investigated the components of science teachers’ PCK that helped students’ learning from the perspective of students. Thus, it is the aim of this study to investigate the level of science teachers’ PCK from students’ perspective, in particular whether or not students of different achieving ability had different views of teachers’ PCK in assisting their learning and understanding. Based on the PCK research literature, six components of PCK have been identified, which were as follows: (1) subject matter knowledge, (2) knowledge of teaching strategies, (3) knowledge of concept representation, (4) knowledge of teaching context, (5) knowledge of students, and (6) knowledge of assessment in learning science. A questionnaire consisting of 56 items on a five-point Likert-type scale were used for data collection from 316 Form Four students (16 years old). One-way analysis of variance revealed that the differences in science teachers’ PCK identified by students of different achieving abilities were statistically significant. Overall, students of various academic achieving abilities considered all the components of PCK as important. The low-achieving students viewed all the components of PCK as being less important compared to the high and moderate achievers. In particular, low-achieving students do not view ‘knowledge of concept representation’ as important for effective teaching. They valued the fact that teachers should be alert to their needs, such as being sensitive to students’ reactions and preparing additional learning materials. This study has revealed that PCK of science teachers should be different for high and low-achieving students and knowledge of students’ understanding plays a critical role in shaping teachers PCK.  相似文献

This qualitative video study explores how two elementary school teachers taught for conceptual understanding throughout different phases of science inquiry. The teachers implemented teaching materials with a focus on learning science key concepts through the development of word knowledge. A framework for word knowledge was applied to examine the students’ level of word knowledge manifested in their talk. In this framework, highly developed knowledge of a word is conceptual knowledge. This includes understanding how the word is situated within a network of other words and ideas. The results suggest that students’ level of word knowledge develops toward conceptual knowledge when the students are required to apply the key concepts in their talk throughout all phases of inquiry. When the students become familiar with the key concepts through the initial inquiry activities, the students use the concepts as tools for furthering their conceptual understanding when they discuss their ideas and findings. However, conceptual understanding is not promoted when teachers do the talking for the students, rephrasing their responses into the correct answer or neglecting to address the students’ everyday perceptions of scientific phenomena.  相似文献

This study adopted a cross-sectional and correlational research design in an attempt to add our understanding of student- and teacher-level factors that help explain variability in students’ science achievement to the existing literature. More specifically, the present article examined students’ science achievement in relation to their constructivist learning environment perceptions, epistemological beliefs, and self-regulation as well as their science teachers’ characteristics. Data were gathered from both 137 science teachers and their 3281 seventh grade students via administering self-report questionnaires. Hierarchical linear modeling (HLM) analysis was conducted to analyze the two-level data (student level and teacher level). Students’ learning environment perceptions, epistemological beliefs, achievement goals, and self-regulation constituted student-level data while teachers’ self-efficacy, achievement goals, and epistemological beliefs constituted teacher-level data. The findings indicated that students’ constructivist learning environment perceptions were significant predictors of their science achievement. Additionally, students with sophisticated epistemological beliefs appeared to be more successful in science. Also, performance avoidance goals were negatively related to science achievement. Among teacher-level variables, teachers’ self-efficacy and sophisticated epistemological beliefs were found to be positively linked to students’ science achievement.  相似文献

Many within the science education community and beyond see practical work carried out by students as an essential feature of science education. Questions have, however, been raised by some science educators about its effectiveness as a teaching and learning strategy. This study explored the effectiveness of practical work by analysing a sample of 25 ‘typical’ science lessons involving practical work in English secondary schools. Data took the form of observational field notes and tape‐recorded interviews with teachers and students. The analysis used a model of effectiveness based on the work of Millar et al. and Tiberghien. The teachers’ focus in these lessons was predominantly on developing students’ substantive scientific knowledge, rather than on developing understanding of scientific enquiry procedures. Practical work was generally effective in getting students to do what is intended with physical objects, but much less effective in getting them to use the intended scientific ideas to guide their actions and reflect upon the data they collect. There was little evidence that the cognitive challenge of linking observables to ideas is recognized by those who design practical activities for science lessons. Tasks rarely incorporated explicit strategies to help students to make such links, or were presented in class in ways that reflected the size of the learning demand. The analytical framework used in this study offers a means of assessing the learning demand of practical tasks, and identifying those that require specific support for students’ thinking and learning in order to be effective.  相似文献

Researchers and policy-makers have recognized the importance of including and promoting socioscientific argumentation in science education worldwide. The Swedish curriculum focuses more than ever on socioscientific issues (SSI) as well. However, teaching socioscientific argumentation is not an easy task for science teachers and one of the more distinguished difficulties is the assessment of students’ performance. In this study, we investigate and compare how science and Swedish language teachers, participating in an SSI-driven project, assessed students’ written argumentation about global warming. Swedish language teachers have a long history of teaching and assessing argumentation and therefore it was of interest to identify possible gaps between the two groups of teachers’ assessment practices. The results showed that the science teachers focused on students’ content knowledge within their subjects, whereas the Swedish language teachers included students’ abilities to select and use content knowledge from reliable reference resources, the structure of the argumentation and the form of language used. Since the Swedish language teachers’ assessment correlated more with previous research about quality in socioscientific argumentation, we suggest that a closer co-operation between the two groups could be beneficial in terms of enhancing the quality of assessment. Moreover, SSI teaching and learning as well as assessment of socioscientific argumentation ought to be included in teacher training programs for both pre- and in-service science teachers.  相似文献

The current paper draws on data generated through group interviews with students who were involved in a larger ethnographic research project performed in three science classrooms. The purpose of the study from which this data was generated, was to understand science teachers’ assessment practices in an upper-secondary school in Sweden. During group interviews students were asked about their conceptions of what were the assessment priority of teachers, why the students were silent during lecturing and their experiences regarding peer- and self-assessments. The research design and analysis of the findings derives from what students told us about their assessments and learning sciences experiences. Students related that besides the results of the written test, they do not know what else teachers assessed and used to determine their grades. It was also found that students did not participate in the discussion on science because of peer-pressure and a fear of disappointing their peers. Student silence is also linked with student conceptions of science learning and student experiences with methodologies of teaching and learning sciences.  相似文献

Energy is a central topic in physics and a key concept for understanding the physical, biological and technological worlds. It is a complex topic with multiple connections with different areas of science and with social, environmental and philosophical issues. In this paper we discuss some aspects of the teaching and learning of the energy concept, and report results of research on this issue. To immerse science teaching into the context of scientific culture and of the students’ cultural world, we propose to select specific driving issues that promote motivation for the construction of science concepts and models. We describe the design and evaluation of a teaching learning path developed around the issue of greenhouse effect and global warming. The experimentation with high school students has shown that the approach based on driving issues promotes students’ engagement toward a deeper understanding of the topic and favours further insight. The evolution of students’ answers indicates a progressively more correct and appropriate use of the concepts of heat, radiation, temperature, internal energy, a distinction between thermal equilibrium and stationary non equilibrium conditions, and a better understanding of greenhouse effect. Based on the results of the experimentation and in collaboration with the teachers involved, new materials for the students have been prepared and a new cycle of implementation, evaluation and refinement has been activated with a larger group of teachers and students. This type of systematic and long term collaboration with teachers can help to fill the gap between the science education research and the actual school practice.  相似文献
