This study investigates the impacts of a year-long professional development program on Kindergarten teachers’ beliefs and practices and the association of these changes with student achievement in mathematics measured by curriculum-based instruments. Although teacher content knowledge was not statistically significantly different before and after participation in the program, changes in teachers’ beliefs and practices were both noticed: a trend towards discovery/connectionist orientation and student-centered practices. Teachers’ gain scores on a measure of mathematics content knowledge was positively related to the linear growth rate of student achievement. 相似文献

In this study, the author implemented a problem-based learning (PBL) experience that allowed students in an advanced science methodology course to explore differentiated instruction. Through working systematically in small, collaborative groups, students explored the nature of differentiated instruction. The objective of the study was to examine pre-service teachers’ developing conceptions of differentiated instruction (DI) as a way to teach for diversity. The author adopted action research as a strategy to explore students’ perceptions of DI in the context of science teaching and learning. Several data collection methods and sources were adopted in the study, including student-generated products, student interviews, classroom observation, and journal writing. Outcomes report on students’ perceptions of both the potential and challenges associated with adopting a DI approach to science teaching and learning. 相似文献

Since A Nation at Risk was released in the 1980s, standards-based reform has been the most dominant trend in American educational policy, and the No Child Left Behind Act pushed the trend further by requiring states to develop rigorous curriculum standards. Though much has been said about these new standards, less has been said about whether or how well professional development helps teachers link their instruction to these standards. This study examined the impact of a professional development program for K-12 science teachers in helping teachers meet state curriculum standards. Seventy-five science teachers in Michigan participated in a 2-week summer workshop that used Problem-Based Learning for improving teachers’ content knowledge and pedagogical content knowledge. Researchers surveyed participating teachers about the change of teachers’ preparedness for standards-based teaching, their expectations to meet state curriculum standards, and whether their expectations were met. In addition, the usefulness of workshop activities was examined. Data analysis showed that to align teaching with state curriculum standards, participating teachers expected to learn instructional strategies and enhance science content knowledge through professional development, and by and large their expectations were well met. Collaboration with colleagues and facilitators helped teachers achieve their goals in terms of teaching within state curriculum standards. These findings have important implications for designing professional development to help teachers align instruction with curriculum standards. 相似文献

This article reports the findings of a 3-year study of a hybrid professional development program designed to prepare science and mathematics teachers to implement GIS in their classrooms. The study was conducted as part of the CoastLines Innovative Technology Experiences for Students and Teachers project funded by the National Science Foundation. Three cohorts of teachers participated in the program, with each participant receiving 40 h of synchronous online instruction and 80 h of in-person instruction and support over an 8-month period. Data from surveys of participants both before and after the program were analyzed using correlation, ordinary least squares, and ordered logit regression analyses. The analyses revealed increases in the self-reported frequency of GIS use and enhanced feelings of preparation, competence, community, and comfort with respect to using GIS for instruction. A composite index of all impact variables was positively influenced as well. The statistical analyses found a strong relationship between self-reported feelings of preparation and use of GIS. Some support was found for the idea that feelings of competence, community, and comfort were related to the teachers’ sense of preparation. The findings suggest that a robust hybrid model of teacher professional development can prepare teachers to use GIS in their classrooms. More research is needed to understand how hybrid models influence the sociopsychological and other dimensions that support teachers’ feelings of preparation to implement GIS. 相似文献

The purpose of this study was to explore the effect of the inquiry-based and explicit–reflective laboratory instruction on preservice science teachers’ (PSTs) conceptions of the nature of science (NOS) aspects. This study was carried out during the Laboratory Application in Science II course. All 52 preservice elementary science teachers enrolled in the course consented to participate in the study; 37 were female and 15 were male, with a mean age of 22.8 years. All had the same science major background, and all of them were juniors. The course provided meaningful and practical inquiry-based experiences, as well as explicit and reflective instruction about NOS. Each week, a specific NOS aspect was targeted related to the inquiry-based laboratory investigation. The design of the study was qualitative and exploratory in nature. At the beginning of the study, the Views of Nature of Science Questionnaire Version B open-ended questionnaire was applied to explore PSTs’ NOS views. At the end of the semester, the same questionnaire was conducted to determine the impact of the explicit–reflective and inquiry-based laboratory instruction. The results showed that many PSTs improved their views of NOS in each element, although to different degrees. 相似文献

A group of teachers?? meaning-making when they are collaboratively analyzing artifacts from practice in local science classrooms in a school-based professional development (PD) project is examined through repeated interviews and represented as meaning-making maps. The interpretation of the teachers?? meaning-making includes both their reference to outcomes from the project and their expressed ideas about teaching and learning of science. All four teachers refer to experiences from experimenting in their classrooms and interpret the collected artifacts in relation to students?? learning. Furthermore, they all felt encouraged to continue collaboration around science. During the interviews, the teachers emphasize various elements apparently connected to concrete challenges they each experience in their professional work. Implications in relation to the design of PD are discussed. 相似文献

To improve the quality of education, the Kuwaiti Ministry of Education has encouraged schools to implement inquiry-based instruction. This study identifies psychosocial factors that predict teachers’ intention to use inquiry-based instruction in their science classrooms. An adapted model of Ajzen’s ( 1985) theory of planned behaviour—the Science Adoption Model—was used to study Kuwaiti science teachers’ beliefs. Four hundred and ninety-six teachers from all the government primary schools in Kuwait completed a questionnaire. The data were analysed using the Statistical Package for the Social Sciences (SPSS) to statistically examine the relationships among the constructs of the model. It was found that teachers’ attitudes towards using inquiry-based instruction significantly predicted their capacity to create and deliver inquiry-based lessons. Although Kuwaiti science teachers held positive beliefs about the implementation of inquiry-based instruction, many factors limited their use of this approach in their science classroom. One clear implication from this study is that educators need to overtly consider teachers’ beliefs as inquiry-based instruction reform is implemented. 相似文献

Our 5-year professional development intervention is designed to promote elementary teachers’ knowledge, beliefs, and practices
in teaching science, along with English language and mathematics for English Language Learning (ELL) students in urban schools.
In this study, we used an end-of-year questionnaire as a primary data source to seek teachers’ perspectives on our intervention
during the first year of implementation. Teachers believed that the intervention, including curriculum materials and teacher
workshops, effectively promoted students’ science learning, along with English language development and mathematics learning.
Teachers highlighted strengths and areas needing improvement in the intervention. Teachers’ perspectives have been incorporated
into our on-going intervention efforts and offer insights into features of effective professional development initiatives
in improving science achievement for all students.

This literature review examined empirical research conducted between 2004 and 2014 regarding 1:1 technologies in K–12 educational settings. Our overarching research question was: What does research tell us about 1:1 technology in K–12 classrooms? We used the constant-comparative method to analyze, code, and induce themes from 46 relevant articles. Findings showed that the studies selected for analyses primarily concentrated on the following themes: effects on student achievement, changes to the classroom environment, classroom uses, effects on learner motivation and engagement, and challenges to classroom integration. In this article, we define each of these themes, describe the implications of the use of technologies on a 1:1 basis in classrooms, and offer suggestions for future research. 相似文献

Two studies were conducted to examine content knowledge changes following 2 weeks of professional development that included scientific research with university scientists. Engaging teachers in scientific research is considered to be an effective way of encouraging knowledge of both inquiry pedagogy and content knowledge. We used concept maps with two cohorts of teachers to assess changes in science teacher knowledge. In study 1, 34 teachers developed pre- and post-concept maps in one of the nine different content areas. A repeated measures analysis of six quantitative scores showed statistically significant increases in knowledge representation. Quantitative and qualitative scoring methods indicate that concept maps are effective for assessing teacher knowledge gains from professional development. Study 2 replicated the results with 24 teachers and provided further information about how knowledge changes. 相似文献

The major science education reform documents emphasize the need for K-12 students to have a robust understanding of nature
of science (NOS), and inservice teachers consequently need to develop their NOS teaching repertoires. This study investigated
the extent to which science teachers were willing to adopt new strategies and activities for teaching NOS in their classrooms.
The participants were 36 elementary, middle, and high school teachers who were completing a year-long physical science professional
development (PD) that included NOS instruction. Data sources consisted of surveys (teachers’ NOS views, teaching practices),
collected work, and responses to post-PD follow-up questions. The professional development course was successful in that teachers
incorporated many of these strategies and activities into their own practice. This study also endeavored to identify factors
that facilitated the adoption of these new approaches to teaching NOS. While personal characteristics such as pre- or post-PD
NOS understandings, NOS gains, and grade level taught were not related to the number of NOS activities incorporated, teachers
from suburban and rural schools were significantly more likely to implement NOS activities. 相似文献

The purpose of this study was to obtain data on United States K-5 elementary school teachers’ self-reported instructional practices with graphical representations. Via an electronic survey, 388 elementary teachers, from throughout the US, reported about their teaching of the interpretation and the production of graphics within science. The main findings indicate that: (1) pointing to or referring to graphical representations in books (92% of respondents) was the most frequently used instructional practice across the disciplines and grade levels; (2) five of nine graphical representations (over 90%) were more frequently used in science instruction than in other content areas, and (3) students’ graphical productions involving drawings, labeling, and oral and written explanations were very infrequent. The findings indicate that while teachers may tacitly use graphics within science instruction, they may not be explicitly teaching about this visual form of communication. 相似文献

This paper considers the circumstances under which science teachers can respond positively and productively to educational
policy reforms in the area of science practical assessment. To understand what might be involved in linking science teachers’
assessment capacities and their professional development, we present illustrative data from recent research studies conducted
in Singapore and Hong Kong showing contrasting approaches taken in the implementation of reforms in science practical assessment.
In Singapore, teachers worked together to select, discuss, clarify and refine their practices as they made decisions about
what to teach and assess. In Hong Kong, teachers took a critical stance towards the new policy and learnt from their own experiences
in order to build their confidence. With the same policy initiative, one group of teachers focused more on the technicalities
of complying with requirements imposed on them while in the other group had their professional consciousness of what they
thought was best for their students provoked so that their practices would be transformed. In an attempt to draw lessons for
other contexts in supporting the implementation of assessment policy reforms through professional development work, we identify
and discuss a range of factors in science teachers’ professional development that arise once in situ professional development work has started. Overall, our intent in this article is to recast assessment reform as a driver
or pivot in teachers’ professional development and learning. To do this it is necessary, we argue, to afford teachers’ experiences
and the processes involved in learning from them greater emphasis in order to ensure the continuance of innovation in the
assessment of laboratory-based work. 相似文献

Teachers’ professional development is a key factor in improving science education, but it shows limited impact when only a small number of teachers is reached, or when it focuses on only one aspect of teachers’ development, such as learning science content, and is disconnected from teachers’ practice. In order to increase the impact of our work on teachers’ professional development, we implemented in 2007 ComPratica, an online network intended to establish a virtual community of practice involving biology teachers and biological education researchers. We present here the results of the first 2 years of this project, obtained through an analysis of the number and distribution of actions performed by the participants in the community, the kinds of activities in which they are engaged, and the themes addressed in their messages. From these data, we conclude that ComPratica is effectively functioning as a community of practice and is leading to changes related to both teachers’ and researchers’ professional development, which seem capable of reducing the research–practice gap in science education. 相似文献

Young children are able to benefit from early science teaching but many preschool teachers have not had opportunities to deepen their own understanding of science or to develop their pedagogical content knowledge (PCK) in relation to specific science topics and concepts. This study presents the results of efficacy research on Foundations of Science Literacy (FSL), a comprehensive professional development program designed to support teachers’ knowledge of early childhood science; their PCK around 2 physical science topics (water, and balls and ramps); and their abilities to plan, facilitate, and assess young children’s learning during inquiry-based science explorations. Research Findings: In a randomized trial with 142 preschool teachers and 1,004 4-year-old children, FSL teachers demonstrated significantly higher quality science teaching in general and greater PCK in the 2 physical science topics than did teachers in comparison classrooms. Furthermore, children in FSL classrooms performed significantly better than children in comparison classrooms on tasks involving floating and sinking, and an instrumental variable analysis suggests that the quality of classroom science instruction mediated the relationship between teacher participation in FSL and student outcomes. Practice or Policy: Findings support the use of comprehensive early science professional development programs designed to bolster teacher knowledge and PCK. 相似文献

In this paper, we present a professional development/upgrading programme in science for early-years teachers and investigate its impact on the teachers’ competencies in relation to their knowledge and teaching of science. The basic idea of the programme was to motivate the teachers by making them members of an action research group aimed at developing and implementing curriculum activities to which they would contribute and thus meaningfully engaging them in their own learning. The programme used a ‘collaborative partnership’ model for the development of the activities. In this model, the collaborative notion is defined as an act of ‘shared creation’: partners share a goal and members bring their expertise to the partnership. Within this context, the partners were a researcher in science education with a background in physics, who also served as a facilitator, and six in-service early-years teachers with a background in early-years pedagogy and developmental sciences, who had many years of experience (classroom experts). These teachers participated in the programme as co-designers, but were involved to a significantly lesser degree than the researcher. The programme procedures comprised group work and individual teachers’ class work. Data sources included teachers’ essays, field-notes, lesson recordings and group-work records. Data were qualitatively analysed. The main results indicate improvement of teachers’ ‘transformed’ knowledge of the subject matter, development/improvement of knowledge of instructional strategies, including factors related to quality of implementation of the activities, knowledge of the pupils and improvement of the teachers’ efficacy. 相似文献
