This paper summarizes the findings from a K-6 professional development program that emphasized scientific inquiry and nature of science within the theme of scientific modeling. During the 2-week summer workshop and follow up school year workshops, the instruction modeled a 5-E learning cycle approach. Pre and posttesting measured teachers’ views of nature of science, inquiry, and scientific modeling. Teachers improved their views of nature of science (NOS) and inquiry by including scientific modeling in their definitions of how scientists work, the empirical nature of science, and the role of observations and inferences in science. Their definitions of science expanded from a knowledge-based orientation to a process-based orientation. Teachers added the use of mathematical formulas to their views of scientific modeling. Using scientific modeling as the central theme was effective in providing positive influence on teachers’ views of inquiry and NOS.  相似文献

This project explores conceptual continuity as a framework for understanding students’ native ways of understanding and describing. Conceptual continuity suggests that the relationship between the use of words in one genre and the scientific genre can exist at varying levels of association. This perspective can reveal the varied relationships between ideas explained in everyday or vernacular genres and their association to scientific explanations. We conducted a 2-year study involving 15 high school baseball players’ understanding of the physics involved in baseball. First, we conducted a quantitative assessment of their science understanding by administering a test prior to season one (2006) and season two (2007). Second, we examined the types of linguistic resources students used to explain their understanding. Third, we revisited our data by using conceptual continuity to identify similarities between students’ conceptual understanding in the informal contexts and their similarities to canonical scientific ideas. The results indicated students’ performance on the multiple-choice questions suggested no significant improvement. The qualitative analyses revealed that students were able to accurately explain different components of the idea by using a diversity of scientific and non-scientific genres. These results call attention to the need to reconstruct our vision of science learning to include a more language sensitive approach to teaching and learning.  相似文献

We explore the professional identities of UK-based secondary science teachers who actively participated in science research for at least six months. The study uses thematic analysis to analyse semi-structured interviews with 17 participants across England and Scotland, from a variety of educational/socio-economic contexts. We found that through participation in research projects, teachers develop a multi-faceted sense of professional identity that includes the roles of teacher, scientist/researcher, mentor and coach. Teachers who are research-active develop complex professional networks that have a positive impact upon their sense of professional worth and self-belief. Through participation in research, teachers identified as both science teachers and scientists and this has been encapsulated in this research as a transition in professional identity to ‘teacher scientist’. The key enabling factor in identification as a ‘teacher scientist’ is a teacher’s positive interaction with scientists/researchers. Teachers are motivated to participate in research projects in response to the enthusiasm of their students and a desire for students to contribute to research that could provide solutions to real-world challenges. This understanding of the capacity of science teachers to become ‘teacher scientists’, and recognising teachers' altruistic motivations, could contribute to teacher retention and recruitment strategies that are less focused on financial incentives.  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

Given reform recommendations emphasizing scientific inquiry and empirical evidence pointing to the difficulties beginning teachers face in enacting inquiry-based science, this study explores a well-started beginning elementary teacher’s (Sofia) beliefs about inquiry-based science and related instructional practices. In order to explore Sofia’s beliefs and instructional practices, several kinds of data were collected in a period of 9 months: a self-portrait and an accompanying narrative, a personal philosophy assignment, three interviews, three journal entries, ten lesson plans, and ten videotaped classroom observations. The analysis of these data showed that Sofia’s beliefs and instructional practices were reform-minded. She articulated contemporary beliefs about scientific inquiry and how children learn science and was able to translate these beliefs into practice. Central to Sofia’s beliefs about science teaching were scientific inquiry and engaging students in investigations with authentic data, with a prevalent emphasis on the role of evidence in the construction of scientific claims. These findings are important to research aiming at supporting teachers, especially beginning ones, to embrace reform recommendations.  相似文献

Preservice science teachers face numerous challenges in understanding and teaching science as inquiry. Over the course of their teacher education program, they are expected to move from veteran science students with little experience learning their discipline through inquiry instruction to beginning science teachers adept at implementing inquiry in their own classrooms. In this study, we used Aikenhead’s (Sci Educ 81: 217–238, 1997, Science Educ 85:180–188, 2001) notion of border crossing to describe this transition preservice teachers must make from science student to science teacher. We examined what one cohort of eight preservice secondary science teachers said, did, and wrote as they both conducted a two-part inquiry investigation and designed an inquiry lesson plan. We conducted two types of qualitative analyses. One, we drew from Costa (Sci Educ 79: 313–333, 1995) to group our preservice teacher participants into one of four types of potential science teachers. Two, we identified successes and struggles in preservice teachers’ attempts to negotiate the cultural border between veteran student and beginning teacher. In our implications, we argue that preservice teachers could benefit from explicit opportunities to navigate the border between learning and teaching science; such opportunities could deepen their conceptions of inquiry beyond those exclusively fashioned as either student or teacher.  相似文献

This paper looks into research aimed to elicit teachers’ ideas about science through the development of resources as questionnaires, problematic tasks and interviews. It is focused on how those ideas are conceptualised and how such conceptualisations have been reflected in the methodological approaches adopted and the advantages and disadvantages of research instruments. This analysis suggests four broad categories to group studies considering substantially different perspectives on teachers’ knowledge. Drawing upon the general finding that teachers tend to develop stereotypical views connected to science, there is an attempt to respond to the question of why such views are not sustainable from an educational point of view. A salient conclusion is that the large majority of such research remains marginal in informing pedagogical practice and faces serious conceptual and methodological challenges. It is also claimed that those studies adopting pedagogical embedded view of ideas about science do illuminate the way forward. The paper ends with a discussion on the implications of teachers’ images of the world of science in their practice.  相似文献

The aim of this research is to ascertain teachers’ opinions on what elements of nature of science (NOS) and science–technology–society relationships (STS) should be taught in school science. To this end an adapted version of the questionnaire developed by Osborne et al. is used. Our results show that experts consulted by Osborne et al. and Spanish teachers confer similar importance on the provisional, experimental, and predictive nature of scientific knowledge based on some of the procedures used such as the drawing up of hypotheses and the analysis and interpretation of data. We also look into the relationship between the teachers’ views and their educational background. 1 1. In this article, Educational Background means the scientific training gained by teachers at university. Results suggest that philosophy teachers are more concerned with the inclusion of NOS and STS topics in science curricula than science teachers, although further studies will be necessary. Some suggestions concerning the university training of science teachers are also discussed.  相似文献

This study examines the self-efficacy of one preservice elementary school teacher (Kasey) during and after her participation in Science in Childhood Education—a 16-week, elementary preservice science methods course. The case study of this teacher is situated in the context of the class as a whole. This is accomplished through interviewing the one teacher and examining artifacts and observations of the entire class. The results of these experiences are studied to determine what changes have taken place in the participants’ self-efficacy in science teaching as well as the one preservice teacher in greater detail. Because self efficacy is influential to student learning, the results of this study have significant implications for the design of elementary teacher education programs and the support of elementary teachers in teaching science.  相似文献

Designing and implementing online or digital learning material is a demanding task for teachers. This is even more the case when this material is used for more engaged forms of learning, such as inquiry learning. In this article, we give an informed account of Go-Lab, an ecosystem that supports teachers in creating Inquiry Learning Spaces (ILSs). These ILSs are built around STEM–related online laboratories. Within the Go-Lab ecosystem, teachers can combine these online laboratories with multimedia material and learning apps, which are small applications that support learners in their inquiry learning process. The Go-Lab ecosystem offers teachers ready–made structures, such as a standard inquiry cycle, alternative scenarios or complete ILSs that can be used as they are, but it also allows teachers to configure these structures to create personalized ILSs. For this article, we analyzed data on the design process and structure of 2414 ILSs that were (co)created by teachers and that our usage data suggest have been used in classrooms. Our data show that teachers prefer to start their design from empty templates instead of more domain–related elements, that the makeup of the design team (a single teacher, a group of collaborating teachers, or a mix of teachers and project members) influences key design process characteristics such as time spent designing the ILS and number of actions involved, that the characteristics of the resulting ILSs also depend on the type of design team and that ILSs that are openly shared (i.e., published in a public repository) have different characteristics than those that are kept private.

Drawing from the phenomenographic perspective, this study investigated Chinese science teacher educators’ conceptions of teaching nature of science (NOS) to preservice science teachers through two semi-structured interviews. The subjects were twenty-four science teacher educators in the developed regions in China. Five key dimensions emerged from the data on the conceptions of teaching NOS, including value of teaching NOS, NOS content to be taught, incorporation of NOS instruction in courses, learning of NOS, and role of the teacher. While some of these dimensions share much similarity with those reported in the studies of conceptions of teaching in general, some are distinctively different, which is embedded in some unique features of teaching NOS to preservice science teachers. These key dimensions can constitute the valuable components of the module or course to train science teachers or teacher educators to teach NOS, provide a framework to interpret the practice of teaching NOS, as well as lay a foundation for probing the conceptions of teaching NOS of other groups of subjects (e.g., school teachers’ conceptions of teaching NOS) or in other contexts (e.g., teaching NOS to in-service teacher).  相似文献

One of the characteristics of effective science teachers is a deep understanding of science concepts. The ability to identify, explain and apply concepts is critical in designing, delivering and assessing instruction. Because some teachers have not completed extensive courses in some areas of science, especially in middle and elementary grades, many professional development programs attempt to strengthen teachers’ content knowledge. Assessing this content knowledge is challenging. Concept inventories are reliable and efficient, but do not reveal depth of knowledge. Interviews and observations are time-consuming. The Problem Based Learning Project for Teachers implemented a strategy that includes pre-post instruments in eight content strands that permits blind coding of responses and comparison across teachers and groups of teachers. The instruments include two types of open-ended questions that assess both general knowledge and the ability to apply Big Ideas related to specific science topics. The coding scheme is useful in revealing patterns in prior knowledge and learning, and identifying ideas that are challenging or not addressed by learning activities. The strengths and limitations of the scoring scheme are identified through comparison of the findings to case studies of four participating teachers from middle and elementary schools. The cases include examples of coded pre- and post-test responses to illustrate some of the themes seen in teacher learning. The findings raise questions for future investigation that can be conducted using analyses of the coded responses.  相似文献

This paper describes Spanish science teachers’ thinking about issues concerning the nature of science (NOS) and the relationships connecting science, technology, and society (STS). The sample consisted of 774 in-service and pre-service teachers. The participants responded to a selection of items from the Questionnaire of Opinions on Science, Technology & Society in a multiple response model. These data were processed to generate the invariant indices that are used as the bases for subsequent quantitative and qualitative analyses. The overall results reflect moderately informed conceptions, and a detailed analysis by items, categories, and positions reveals a range of positive and negative conceptions about the topics of NOS dealt with in the questionnaire items. The implications of the findings for teaching and teacher training on the themes of NOS are discussed.  相似文献

This paper investigates how key elements of school culture are associated with teachers’ capacity to find and act on new information. We analyzed survey data from 3,579 teachers located in 117 schools which were a randomly selected sample from 9 states in the US. We found that school cultural components such as academic press, student support, and trust and respect among teachers promote teachers’ capacity for organizational learning. We also found that the role of teacher professional culture in molding the capacity for organizational learning is critical. In terms of school contexts, we identified that school level (elementary, middle, and high school) was associated with teachers’ capacity for organizational learning in 2 different ways. First, as the school level increases, the capacity for organizational learning tends to decrease. Second, as school level increases, the positive relation between reflective dialogue and teachers’ capacity for organizational learning is weakened. Implications of these results are discussed.  相似文献
