In this nested mixed methods study I investigate factors influencing preservice elementary teachers’ adaptation of science curriculum materials to better support students’ engagement in science as inquiry. Analyses focus on two ‘reflective teaching assignments’ completed by 46 preservice elementary teachers in an undergraduate elementary science methods course in which they were asked to adapt existing science curriculum materials to plan and enact inquiry-based science lessons in elementary classrooms. Data analysis involved regression modeling of artifacts associated with these lessons, as well as in-depth, semester-long case studies of six of these preservice teachers. Results suggest that features of the existing science curriculum materials, including measures of how inquiry-based they were, have a relatively small influence on the preservice teachers’ curricular adaptations, while teacher-specific variables account for a much greater percentage of the variance. Evidence from the case studies illustrates the critical impact of the preservice teachers’ field placement contexts as an explanatory, teacher-specific factor in their curricular adaptations. These findings have important implications for science teacher educators and science curriculum developers, in terms of not only better understanding how preservice teachers engage with curriculum materials, but also how programmatic features of teacher education programs influence their ability to do so. 相似文献

Since the beginning of the reform movement in science education, there has been concern that elementary teachers lack the science content knowledge (SCK) needed to engage students in authentic scientific inquiry. This study included 19 preservice elementary teachers and examined the development of their SCK within the context of a uniquely designed elementary science methods course. A project-developed science knowledge test was administered at the beginning and the end of the science methods course, before and after science content was covered concurrent with modeled pedagogy. The preservice elementary teachers had adequate knowledge of low difficulty science content on the pretest, but demonstrated improvement on moderate and difficult science content, especially on topics emphasized in the methods course. Data analyses conducted on change in SCK using analysis of variance were statistically significant and demonstrated a large effect size. Details are discussed, along with large-scale implications and recommendations for elementary science teacher education. 相似文献

This study examined relationships between conceptual understanding, self-efficacy, and outcome expectancy beliefs as preservice teachers learned science in a constructivist-oriented methods class. Participants included 49 preservice elementary teachers. Analysis revealed that participants increased in self-efficacy, outcome expectancy, and conceptual understanding. Engaging preservice teachers in hands-on, minds-on activities and discussion were important contributors. Participants reported that they would be inclined to teach from a constructivist perspective in the future. One implication from this study is that increasing the quantity of science content courses that preservice elementary teachers are required to take may not be sufficient to overcome their reluctance to teach science if some of their learning does not take place in a constructivist environment. In our teaching, we have tried to integrate pedagogy with learning science content. 相似文献

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

This study investigated the effectiveness of an Early Childhood Education science methods course that focused exclusively
on providing various mastery (i.e., enactive, cognitive content, and cognitive pedagogical) and vicarious experiences (i.e.,
cognitive self-modeling, symbolic modeling, and simulated modeling) in increasing preservice elementary teachers’ self-efficacy
beliefs. Forty-four preservice elementary teachers participated in the study. Analysis of the quantitative (STEBI-b) and qualitative
(informal surveys) data revealed that personal science teaching efficacy and science teaching outcome expectancy beliefs increased
significantly over the semester. Enactive mastery, cognitive pedagogical mastery, symbolic modeling, and cognitive self-modeling
were the major sources of self-efficacy. This list was followed by cognitive content mastery and simulated modeling. This
study has implications for science teacher educators. 相似文献

Elementary teachers face increasing demands to engage children in authentic science process and argument while simultaneously preparing them with knowledge of science facts, vocabulary, and concepts. This reform is particularly challenging due to concerns that elementary teachers lack adequate science background to teach science accurately. This study examined 81 in-classroom inquiry science lessons for preservice education majors and their cooperating teachers to determine the accuracy of the science content delivered in elementary classrooms. Our results showed that 74 % of experienced teachers and 50 % of student teachers presented science lessons with greater than 90 % accuracy. Eleven of the 81 lessons (9 preservice, 2 cooperating teachers) failed to deliver accurate science content to the class. Science content accuracy was highly correlated with the use of kit-based resources supported with professional development, a preference for teaching science, and grade level. There was no correlation between the accuracy of science content and some common measures of teacher content knowledge (i.e., number of college science courses, science grades, or scores on a general science content test). Our study concluded that when provided with high quality curricular materials and targeted professional development, elementary teachers learn needed science content and present it accurately to their students. 相似文献

Part of the work of teaching elementary science involves evaluating elementary students' work. Depending on the nature of the student work, this task can be straightforward. However, evaluating elementary students' representations of their science learning in the form of scientific models can pose significant challenges for elementary teachers. To address some of these challenges, we incorporated a modeling-based elementary science unit in our elementary science teaching methods course to support preservice teachers in gaining knowledge about and experience in evaluating students' scientific models. In this study, we investigate the approaches and criteria preservice elementary teachers use to evaluate elementary student-generated scientific models. Our findings suggest that with instruction, preservice elementary teachers can adopt criterion-based approaches to evaluating students' scientific models. Additionally, preservice teachers make gains in their self-efficacy for evaluating elementary students' scientific models. Taken together, these findings indicate that preservice teachers can begin to develop aspects of pedagogical content knowledge for scientific modeling. 相似文献

This study explored a modified version of Japanese Lesson Study to determine whether and how it influenced preservice elementary teachers in their abilities to deliver science lessons that included nature of science (NOS) to their own students. We used a case study approach that focused on one subset of a cohort of preservice elementary teachers within their field placement settings. Data sources included lesson plans, lesson feedback forms, videotapes of delivered lessons, and videotapes of lesson study feedback sessions. Early in the semester peers provided feedback on content, and later in the semester peers provided feedback on classroom management as well as content during the lesson study feedback sessions. We found that preservice elementary teachers were able to provide feedback to their peers regarding how to include NOS in their science lessons, yet did not naturally included NOS connections within their own lessons. 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

This study examined the views, and the retention of these views, of 19 preservice elementary teachers as they learned about nature of science (NOS). The preservice teachers participated in a cohort group as they took a science methods course during which they received explicit reflective instruction in nature of science. Through Views of Nature of Science version B (VNOS‐B) surveys and interviews it was found that most preservice teachers held inadequate ideas of nature of science prior to instruction, but improved their views after one semester of instruction in the science methods course. However, 5 months after instruction, the graduate preservice teachers were again interviewed and it was found that several of the students reverted back to their earlier views. The results are interpreted through Perry's scheme, and implications and recommendations for elementary science teacher education are made. © 2005 Wiley Periodicals, Inc.

Research has identified the value of learners using technology to construct their own representations of science concepts. In this study, we investigate how learners, such as preservice elementary teachers, design and make a narrated animation to represent their science knowledge. The type of animation exemplified is called a “Slowmation” (abbreviated from “Slow Animation”), which is a simplified way for preservice teachers to make an animation that integrates features from claymation, object animation, and digital storytelling. Drawing on semiotic theory, a case study of three preservice elementary teachers, who were audio and video recorded as they created a slowmation, illustrates how the construction process enabled them to engage with a science concept in multiple ways. Findings suggest that when preservice teachers create a slowmation, they design and make a sequence of five representations, each being a semiotic system with particular affordances that link as a semiotic progression: (i) research notes; (ii) storyboard; (iii) models; and (iv) digital photographs, which culminate in (v) a narrated animation. In this study, the authors present their theoretical framework, explain how the preservice teachers created a slowmation using a sequence of representations to show their science knowledge and discuss the implications of these findings for learners in universities and schools. © 2011 Wiley Periodicals, Inc.

The intent of this study was to investigate the influence of both locus of control as well as three instructional strategies, which differed in their respective emphases on science content, teaching methods, and process science, to foster an understanding of the nature of science. Data were collected from 135 elementary preservice teachers enrolled in science teaching methods courses at the endpoint of three sequences: (a) introductory process instruction with three subsequent semesters of integrated science content and teaching methods, (b) process instruction with separate subsequent content and teaching methods, and (c) only science content with subsequent teaching methods. Statistical procedures included ANOVA, regression, and correlation. Results revealed that the nature of science was most predictable for a separate process/content/teaching methods strategy. Major conclusions were (1) logical thinking ability was the most influential predictor of understanding the nature of science and (2) separate rather than integrated experiences in content and teaching methods were superior in developing an understanding of the nature of science. Implications for preservice elementary teacher preparation are discussed. 相似文献

Inadequate science knowledge of preservice teachers enrolled in science methods courses not only limits their mastery of effective teaching practices, but also may foster negative attitudes toward science teaching. This study investigated the influence of science knowledge upon attitudes toward science teaching in a one-semester elementary science methods course by embedding a videodisk-based instructional component to remediate knowledge deficiencies. Preservice teachers in the experimental group first learned core concepts in physical and earth science through a series of 24 interactive videodisk lessons and then used the concepts as a foundation for preparing and presenting model science lessons. Results showed that the experimental group overcame their initial knowledge deficiencies by mastering the core concepts presented (mean proportion correct on mastery test = 0.91), with multivariate covariance analysis confirming that the experimentals gain in science knowledge was significantly greater than comparable controls in the parallel science methods sections. Additionally, as a result of mastering the core concepts underlying earth science, preservice teachers using the videodisk instruction also displayed significantly greater confidence in their understanding of science knowledge and more positive attitudes toward science teaching at the elementary levels. Implications for improving elementary science teaching through preservice and in-service training are discussed. 相似文献

In broad terms, this study describes preservice elementary teachers' beliefs, conceptions, and practices during the mathematics methods course and teaching practica of a teacher education program. In particular, the study employs qualitative data to investigate preservice teachers' views of mathematical and pedagogical content knowledge. The study reveals symbiotic relationships between their views of content knowledge and their instructional actions which remain problematic. With unwavering beliefs and practices, and without reconceptualizing their roles as future elementary teachers, at the end of the semester the preservice teachers emerge as poor duplicators of mathematics methods instead of initiators of learning. 相似文献

Currently, it is strongly suggested that our thought processes are largely metaphorical in nature. Indeed, the metaphors we use not only represent the way we perceive the world and reality but also shape our professional ideas, attitudes, and practices. This study employs metaphor as a means of research to provide insights into the images prospective classroom teachers have of themselves as future teachers (i.e., professional self-images), their elementary teachers (i.e., former classroom teachers), and their cooperating teachers (i.e., supervisors of student teaching practices). Data for this study were gathered through the administration of a Likert-style questionnaire consisting of 20 metaphorical images of “classroom teacher” to 363 exit level elementary teacher education students enrolled in the Faculty of Education of Selcuk University in Turkey during the 2002–2003 academic year. Results indicate that the teacher candidates in this study appear to be less teacher-centered and more student-centered than their both elementary and cooperating teachers. Also, female teacher candidates appear to be less teacher-centered and more student-centered than their male peers. Implications for preservice teacher education and further research are discussed. 相似文献

Seeing the relevance of tasks for future use is important for developing value and interest in them. We employed a pre- and post-test quasi-experimental design using a mixed-methods approach to examine if reflecting on the relevance of technology to future teaching practices influences elementary and secondary preservice teachers’ utility value and interest toward technology integration. The findings from 111 preservice teachers revealed that reflecting on the connections of technology to future teaching increased their maintained interest in technology integration regardless of their situational interest levels. Reflections also helped them recognize technology-supported classroom management strategies in their current implementations. Differences observed between elementary and secondary preservice teachers highlighted a need for helping secondary preservice teachers develop higher interest and deeper understanding of utility values of technologies for future practices. Results also underscored the importance of emphasizing various benefits of technology regarding collaboration, assessment, and self-paced learning—utility values that were minimally observed in the study. 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

This study explored preservice elementary teachers' and their mentors' understanding of the essential features of inquiry-based teaching through the use of evidence-based reflection. The web-based video analysis tool (VAT) system was used to support preservice teachers' and mentors' evidence-based reflection during field experiences. Major data sources included VAT reflections and individual interviews. Data analysis indicated that the preservice teachers had been involved in various activities designed to support their understanding of inquiry features in a science methods class; they did not implement all of the features in their actual teaching. Both preservice teachers and mentors had difficulty connecting appropriate inquiry features to each teaching episode, which indicates their lack of understanding of inquiry. Both the preservice teachers and mentors had different levels of understanding for each feature. That is, they tended to understand certain features better than others. They interpreted each feature of inquiry-based science teaching too broadly. They also either had a teacher-centered view or tended to focus on issues unrelated to science teaching. 相似文献

This mixed‐methods investigation compared the relative impacts of instructional approach and context of nature of science instruction on preservice elementary teachers' understandings. The sample consisted of 75 preservice teachers enrolled in four sections of an elementary science methods course. Independent variables included instructional approach to teaching nature of science (implicit vs. explicit) and the context of nature of science instruction (as a stand‐alone topic vs. situated within instruction about global climate change and global warming). These treatments were randomly applied to the four class sections along a 2 × 2 matrix, permitting the comparison of outcomes for each independent variable separately and in combination to those of a control group. Data collection spanned the semester‐long course and included written responses to pre‐ and post‐treatment administrations of the VNOS‐B, semi‐structured interviews, and a variety of classroom artifacts. Qualitative methods were used to analyze the data with the goal of constructing profiles of participants' understandings of the nature of science and of global climate change /global warming (GCC/GW). These profiles were compared across treatments using non‐parametric statistics to assess the relative effectiveness of the four instructional approaches. Results indicated that preservice teachers who experienced explicit instruction about the nature of science made statistically significant gains in their views of nature of science regardless of whether the nature of science instruction was situated within the context of GCC/GW or as a stand‐alone topic. Further, the participants who experienced explicit nature of science instruction as a stand‐alone topic were able to apply their understandings of nature of science appropriately to novel situations and issues. We address the implications of these results for teaching the nature of science in teacher preparation courses. © 2010 Wiley Periodicals, Inc., Inc. J Res Sci Teach 48: 414–436, 2011 相似文献
