Climate change is one of the most pressing challenges facing society, and climate change educational models are emerging in response. This study investigates the implementation and enactment of a climate change professional development (PD) model for science educators and its impact on student learning. Using an intrinsic case study methodology, we focused analytic attention on how one teacher made particular pedagogical and content decisions, and the implications for student’s conceptual learning. Using anthropological theories of conceptual travel, we traced salient ideas through instructional delivery and into student reasoning. Analysis showed that students gained an increased understanding of the enhanced greenhouse effect and the implications of human activity on this enhanced effect at statistically significant levels and with moderate effect sizes. However, students demonstrated a limited, though non-significant gain on the likely effects of climate change. Student reasoning on the tangible actions to deal with these problems also remained underdeveloped, reflecting omissions in both PD and teacher enactment. We discuss implications for the emerging field of climate change education. 相似文献

This research examines factors influencing elementary science teacher learning as they participate in professional development with and enactment of educative curricula in comparison with learning following limited professional development and enactment of traditional curricula. Using a randomized cluster design (125 teachers and 2,694 students in 4th—5th grades) that met the What Works Clearinghouse standards without reservations, teacher learning was conceptualized using four outcomes. Data were analyzed using standard single-level multiple regression models and possible mediation models for the teacher outcomes were considered using piecewise multiple regression and path analytic approaches. Treatment group teachers experienced greater increases in content knowledge, views of science inquiry, beliefs about reform-based teaching, and teaching self-efficacy than comparison group teachers. The findings indicate that what teachers learn from the combination of professional development and teaching with educative curriculum varies according to what their knowledge and beliefs are on entering the experience. Surprisingly, high entry-level self-efficacy was associated not only with lower learning gains for the teachers, but also for their students. Finally, teachers' space science learning and that of their students are implicated as mediators of the positive effect of the professional development and educative curriculum enactment on teacher beliefs about reform science teaching. This work refines and extends a theoretical framework of teachers' participatory relationship with curricula. 相似文献

This qualitative investigation explored the beliefs and practices of one secondary science teacher, Diane, who differentiated instruction and studied how technology facilitated her differentiation. Diane was selected based on the results of a previous study, in which data indicated that Diane understood how to design and implement proactively planned, flexible, engaging instructional activities in response to students’ learning needs better than the other study participants. Data for the present study included 3 h of semi-structured interview responses, 37.5 h of observations of science instruction, and other artifacts such as instructional materials. This variety of data allowed for triangulation of the evidence. Data were analyzed using a constant comparative approach. Results indicated that technology played an integral role in Diane’s planning and implementation of differentiated science lessons. The technology-enhanced differentiated lessons employed by Diane typically attended to students’ different learning profiles or interest through modification of process or product. This study provides practical strategies for science teachers beginning to differentiate instruction, and recommendations for science teacher educators and school and district administrators. Future research should explore student outcomes, supports for effective formative assessment, and technology-enhanced readiness differentiation among secondary science teachers. 相似文献

At institutions striving to maintain face-to-face field placements and instruction amidst the COVID-19 pandemic, circumstances changed daily in response to new developments at the university, local school districts, and personal circumstances. This mixed-methods study explored and evaluated the adaptations made to early childhood teacher preparation courses in an undergraduate program in order to provide relevant training through a variety of instructional modalities including face-to-face, virtual, hypothetical, and mixed reality. Focused on maintaining professional standards through adapted coursework designed to meet student learning outcomes, instructors reflected on multiple instructional modalities and analysis of demonstrable learning outcomes for students in a four-year bachelor’s degree program resulting in state teacher certification. Data were collected from students from three different cohorts (n?=?26) through course assignments, reflections, and instructor- and self-assessments. Results highlight several areas where students found success in meeting professional standards in new ways including: knowledge of development, relevant and responsive curriculum, collaborative engagement, cultural and familial knowledge, inclusive and individualized design, and flexibility and adaptability. Students were prepared to teach in the following ways: designing curriculum, implementation, and reflective practice. Students felt unprepared to teach citing needing more practice and continued skills development. These findings highlight the need for flexibility in the face of the pandemic and underscore the importance of using the new knowledge and practices generated about student learning to reinvent early childhood teacher education programs when faced with post-pandemic realities.

As part of a larger project aimed at promoting science and literacy for culturally and linguistically diverse elementary students, this study has two objectives: (a) to describe teachers' initial beliefs and practices about inquiry‐based science and (b) to examine the impact of the professional development intervention (primarily through instructional units and teacher workshops) on teachers' beliefs and practices related to inquiry‐based science. The research involved 53 third‐ and fourth‐grade teachers at six elementary schools in a large urban school district. At the end of the school year, teachers reported enhanced knowledge of science content and stronger beliefs about the importance of science instruction with diverse student groups, although their actual practices did not change significantly. Based on the results of this first year of implementation as part of a 3‐year longitudinal design, implications for professional development and further research are discussed. © 2004 Wiley Periodicals, Inc.

This paper compares and contrasts the impacts of three professional development designs aimed at middle school Earth science
teachers on how teachers plan and enact instruction. The designs were similar in their alignment to research-based practices
in science professional development: each design was of an extended duration and time span, included follow-up support to
teachers, and incorporated active learning approaches in the professional development. In addition, the designs had a high
level of coherence with other reform activities and with local standards. The main difference among the designs was in the
roles of teachers in designing, adopting, or adapting curriculum materials. Evidence from teacher survey and observation data
indicated that all programs had positive impacts on how teachers planned and enacted teaching for understanding, but differences
among programs was more evident in their impacts on instructional planning. 相似文献

Teachers' learning to facilitate high‐level student thinking: Impact of a video‐based professional development 
下载免费PDF全文
下载免费PDF全文 Attaining the vision for science teaching and learning emphasized in the Framework for K‐12 Science Education and the next generation science standards (NGSS) will require major shifts in teaching practices in many science classrooms. As NGSS‐inspired cognitively demanding tasks begin to appear in more and more science classrooms, facilitating students' engagement in high‐level thinking as they work on these tasks will become an increasingly important instructional challenge to address. This study reports findings from a video‐based professional development effort (i.e., professional development [PD] that use video‐clips of instruction as the main artifact of practice to support teacher learning) to support teachers' learning to select cognitively demanding tasks and to support students' learning during the enactment of these tasks in ways that are aligned with the NGSS vision. Particularly, we focused on the NGSS's charge to get students to make sense of and deeply think about scientific ideas as students try to explain phenomena. Analyses of teachers' pre‐ and post‐PD instruction indicate that PD‐participants began to adopt instructional practices associated with facilitating these kinds of student thinking in their own classrooms. The study has implications for the design of video‐based professional development for science teachers who are learning to facilitate the NGSS vision in science classrooms. 相似文献

Teaching outdoors has been established as an important pedagogical strategy; however, science classes rarely take place outside. Previous research has identified characteristics of teachers who have integrated out-of-classroom opportunities into their teaching repertoire; yet little is understood as to why teachers make these different pedagogical decisions. This paper explores the relationship between secondary science teachers’ beliefs and their pedagogical practice during a two-year professional development programme associated with the ‘Thinking Beyond the Classroom’ project. Using data from lesson observations, interviews, session questionnaires and field notes, six teacher case studies were developed from participants completing the programme. Data analysis reveals that teachers who successfully taught outside generally held social constructivist beliefs about learning and valued ‘authentic’ science opportunities. Conversely, teachers who were less successful in teaching outside generally held traditional learning beliefs and simply valued the outdoors for the novelty and potential for fun. All the case study teachers were concerned about managing student learning outside, and for the majority, their concerns influenced their subsequent pedagogical practice. The findings are discussed in detail, as are the implications for pre-service and in-service professional development programmes related to outdoor science learning. 相似文献

Teachers play a critical role in successfully implementing science education reforms in the United States to provide high-quality science learning opportunities to all students. However, the differentiated ways in which teachers make decisions about their science teaching are not well understood. This study takes a person-centered approach by applying latent profile analysis to examine how cognitive (pedagogical content knowledge) and motivational (instructional goal orientations, self-efficacy beliefs, and reform values) characteristics combine to form science teacher profiles in middle school. Predictors of profile membership (bachelor's degree, school %FRL) and both teacher (science instructional practices) and student (science achievement, engagement, and self-efficacy) outcomes related to the teacher profiles were also examined. Five science teacher profiles were identified (severely discouraged but reform oriented, discouraged but reform oriented, conventional, confident and mastery oriented, and confident with multiple goal approaches) that represented unique configurations of cognitive and motivation characteristics. Additionally, findings showed that the teacher profiles were significantly related to three dimensions of science instructional practice including communication, discourse, and reasoning. Finally, the teacher profiles were significantly related to student science achievement and motivational outcomes. Implications for differentiated approaches to teacher professional learning and supports for science instruction are discussed. 相似文献

This study presents a model of Transformative Professional Development (TPD) for use in sustained, collaborative, professional
development of teachers in urban middle school science. TPD focuses on urban science teacher change and is responsive to school
climate, teacher needs, and teacher beliefs with the intention of promoting change in practice. In this study, TPD was used
to meet the needs of individual teachers and the collective needs of schools in reform efforts. The experiences of the eight
teachers engaged in this process of professional growth, including their changes in practices and beliefs, provide the focus
of this paper. Findings in this study revealed that through the use of TPD, participants in this study improved science teaching
effectiveness and began to transform their negative school climate and create positive classroom learning environments.

This study investigated how professional development featuring evidence‐based customization of technology‐enhanced curriculum projects can improve inquiry science teaching and student knowledge integration in earth science. Participants included three middle school sixth‐grade teachers and their classes of students (N = 787) for three consecutive years. Teachers used evidence from their student work to revise the curriculum projects and rethink their teaching strategies. Data were collected through teacher interviews, written reflections, classroom observations, curriculum artifacts, and student assessments. Results suggest that the detailed information about the learning activities of students provided by the assessments embedded in the online curriculum motivated curricular and pedagogical customizations that resulted in both teacher and student learning. Customizations initiated by teachers included revisions of embedded questions, additions of hands‐on investigations, and modifications of teaching strategies. Student performance improved across the three cohorts of students with each year of instructional customization. Coupling evidence from student work with revisions of curriculum and instruction has promise for strengthening professional development and improving science learning. © 2010 Wiley Periodicals, Inc.

We have designed a model for transformational science teaching focused on linking theory and practice through curriculum decision making that has been the framework for professional development sessions for middle-grade science teachers during the past 5 years. Interviews with teachers revealed that their experiences with curriculum development were of significant value in making decisions concerning the design of classroom environments. As teachers reflected on current research about teaching and learning, in collaboration with university scientists and science educators, they were informed by theoretical perspectives which held implications for their practice. Curriculum development became a vehicle for professional development and school reform; however, it was vital that the teachers were in clear communication with their administrators and communities concerning reform issues. Students and teachers from schools implementing the model and from control sites were interviewed to determine the model's influence on instructional practices and student attitude and achievement in science. The five-phase model for transformational science teaching is discussed here, accompanied by teacher comments about tensions experienced at each phase. This discussion is followed by an analysis of teacher and student interview data that reveals teachers' use of instructional strategies and students' attitudes toward science. Results and analysis of student performance on a mandated end-of-grade science test are also included. From this evidence, we recommend a new design for professional development opportunities for teachers that engages them in decision making as they reflect about the connections between theory and practice and the value of continually testing, revising, and reevaluating curriculum and instructional issues.

In order to understand how prospective teachers develop knowledge for teaching, researchers must identify the types of knowledge that are integral to effective science teaching. This case study investigated how 4 prospective secondary biology teachers’ science teaching orientations, knowledge of science learners, and knowledge of instructional sequence, developed during a post-baccalaureate teacher education program. Data sources included a lesson planning task and two interview-observation cycles during the participants’ year-long internship. Over the course of a year, the participants’ science teaching orientations were based primarily on their K-16 learning experiences, and were robust and highly resistant to change. The prospective teachers became more aware of student learning difficulties, and therefore, developed more elaborated knowledge of the requirements of learning. They consistently sequenced instruction in ways that gave priority to transmitting information to students. Prospective teachers’ development of knowledge of student understanding of science and instructional sequence were congruent with their science teaching orientations. Implications are given for teacher education and future research. 相似文献

Every aspect of teaching, including the instructional method, the course content, and the types of assessments, is influenced
by teachers’ attitudes and beliefs. Teacher education programs play an important role in the development of beliefs regarding
teaching and learning. The purpose of the study was to document pre-service teachers’ views on science, scientists, and science
teaching as well as the relations between these views and the offered courses over several years spent in an elementary science
teacher training program. The sample consisted of 145 pre-service elementary science teachers who were being trained to teach
general science to students in the 6th through 8th grades. The research design was a cross-sectional study. Three different
instruments were used to collect the data, namely, the “Draw a Scientist Test”, “Draw a Science Teacher Test”, and “Students’
Views about Science” tests. The elementary science teacher training program influenced pre-service science teachers’ views
about science, scientists and science teaching to different degrees. The most pronounced impact of the program was on views
about science teaching. Participants’ impressions of science teaching changed from teacher-centered views to student-centered
ones. In contrast, participants’ views about scientists and science did not change much. This result could be interpreted
as indicating that science teacher training programs do not change views about science and scientists but do change beliefs
regarding teaching science. 相似文献

The recent next generation science standards in the United States have emphasized learning about complex systems as a core feature of science learning. Over the past 15 years, a number of educational tools and theories have been investigated to help students learn about complex systems; but surprisingly, little research has been devoted to identifying the supports that teachers need to teach about complex systems in the classroom. In this paper, we aim to address this gap in the literature. We describe a 2-year professional development study in which we gathered data on teachers’ abilities and perceptions regarding the delivery of computer-supported complex systems curricula. We present results across the 2 years of the project and demonstrate the need for particular instructional supports to improve implementation efforts, including providing differentiated opportunities to build expertise and addressing teacher beliefs about whether computational-model construction belongs in the science classroom. Results from students’ classroom experiences and learning over the 2 years are offered to further illustrate the impact of these instructional supports. 相似文献

Abstract As investments in K–12 math and science professional development programs expanded over the past decade, researchers and policymakers have questioned whether and how such programs work to improve student learning. This article summarizes the current knowledge-base and offers a theoretical framework researchers can use to design studies that explore mechanisms through which professional development programs influence teacher knowledge, teacher practices, and ultimately student achievement. We quantitatively pool the most rigorous evaluation research available to determine whether currently held beliefs in the field are supported by the evidence. Although this study does find some support for the guidance propounded by experts, it cautions policymakers and practitioners that the current evidence base is thin. We urge researchers to build on what we have learned through theory and practice to increase the rigor of evaluations on this important topic by incorporating valid and reliable measures of professional development components as well as valid measures of teacher knowledge and practices. 相似文献

The experiences of middle school science teachers at two schools in the southeastern US who participated in collaborative,
sustained, whole-school professional development and their implementation of standards-based instructional practices are the
focus of this study. Participants were involved in their second year of the professional development experience. The research
question that was explored was “How are science teachers implementing standards-based instruction while participating in effective
professional development experiences?” Data collected in the form of teacher interviews and classroom observations using an
observation protocol. Findings indicate that even with effective professional development, teachers implement standards-based
instructional practices at varying levels. The reasons for these differences are discussed and the role of teacher beliefs
and the impact of beliefs, experience and support from administrators on professional development efforts are discussed. Implications
for future science education reform stakeholders and professional development efforts are revealed. 相似文献
