The purpose of this study was to assess differences between Nigerian junior and senior preservice teachers’ science teaching efficacy beliefs. Data in this study were collected from a total number of 221 preservice teachers enrolled in junior and senior secondary science teacher education programs in Nigeria using Science Teaching Efficacy Belief Instrument (STEB-B) (Enoch and Riggs in Sci Educ 74:625–638 1990). Results indicated that junior secondary preservice teachers were as efficacious as their senior secondary preservice teachers on the two dimensions of STEB-B. In addition, analyses did not reveal any significant gender differences on the two dimensions of STEB-B.  相似文献

This study examined changes in middle school teachers’ beliefs about inquiry, implementation of inquiry practices, and self-efficacy to teach science through inquiry after participating in a year-long professional development program. The professional development model design was based on Bandura’s (1986) social cognitive theory of learning and literature on effective professional development. Using the Electronic Quality of Inquiry Protocol (EQUIP) before and after the program (Marshall, Smart & Horton, 2010), teachers’ quality of inquiry instruction significantly increased across all 4 EQUIP factors. To assess teachers’ inquiry teaching efficacy, the Teaching Science as Inquiry (TSI; Dira-Smolleck, 2004) instrument was administered 3 times to the teacher participants. Changes between time points of TSI administration were examined for personal self-efficacy and outcome expectancy across 5 essential features of classroom inquiry. Findings for the personal self-efficacy scale showed statistically significant gains from pre-Institute to 1-year follow-up for all 5 inquiry features. Teachers’ outcome expectancy beliefs significantly increased across the program for 3 of the 5 essential features of inquiry. The results indicate the effectiveness of the professional development model at increasing the participants’ inquiry efficacy as well as the quality of their inquiry instruction. Our study provides evidence to support the need to include collaborative practice-teaching and reflection opportunities within professional development models that aim to increase teachers’ use of inquiry-based instructional strategies.  相似文献

A research-based framework for teaching science is a heuristic tool used to help preservice teachers conceptualize many complexities of teaching while making explicit the strategy to use a research-based body of professional knowledge to inform instructional decision-making (Clough, 2003, Paper presented at the annual meeting of the Association for the Education of Teachers in Science, St. Louis, MO). Elementary preservice teachers frequently struggle to apply this knowledge to classroom decisions (Madsen, 2002, Paper presented at the annual meeting of the North Central Association for the Education of Teachers of Science, Bettendorf, IA). This study examined the effects of using a video case-analysis within an elementary science methods course focused on the development of a research-based framework. Students in two course sections completed a unit plan, and students in one section completed the video analysis. Video analysis students’ performance on an oral defense with the instructor was compared with oral defense performance from students in the unit plan group. Video analysis students outperformed their peers on questions related to how learning theories influence decisions of selecting content, explaining the use of questioning, and the use of self assessment strategies. Despite these differences, students in both groups still perceive teaching as primarily accomplished through activities and have difficulties understanding the critical role of the teacher in promoting student goals. This study raises issues regarding teachers’ knowledge development during preservice experiences.  相似文献

Research investigating science teaching efficacy was conducted in 1 Australian university. A sample of 314 elementary preservice teachers responded to the Science Teaching Efficacy Belief Instrument (STEBI; L. G. Enochs & I. M. Riggs, 1990), which assesses 2 teaching efficacy dimensions: Personal Science Teaching Efficacy Beliefs (PSTEB) and Science Teaching Outcome Expectancy (STOE). Confirmatory factor analysis substantiated this 2-factor structure. The use of this instrument revealed that the completion of 2 science teaching subjects within the preservice program had a significant effect on the PSTEB, but not the STOE. Similarly, the number of high school science subjects studied by these elementary preservice teachers had a significant effect on PSTEB, but not STOE. However, neither gender nor the particular high school science subjects studied by these elementary preservice teachers had a significant effect on either the PSTEB or the STOE.  相似文献

This paper presents an overview of the procedures used to develop and validate an instrument to measure the self-efficacy beliefs of prospective elementary teachers about equitable science teaching and learning. The instrument, titled the SEBEST, was based on the work of Ashton and Webb (1986a, 1986b) and Bandura (1977, 1986). It was modeled after the Science Teaching Efficacy Belief Instrument (STEBI) (Riggs, 1988) and the Science Teaching Efficacy Belief Instrument for Prospective Teachers (STEBI-B) (Enochs & Riggs, 1990). Based on the standardized development procedures used and associated evidence, the SEBEST appears to be a content and construct valid instrument, with high internal reliability qualities. "Most probable response" plots are introduced and used to bring meaning to SEBEST raw scores.  相似文献

This study explored the effects of community-based service-learning (CBSL), supplemented with discussions and activities about diversity, on the self-efficacy beliefs of preservice elementary teachers regarding equitable science teaching and learning for diverse student groups. The study was conducted with 81 preservice teachers enrolled in four sections of an elementary science methods course over a semester. Employing a mixed-methods research design, data were collected using pretests–posttests with the study sample and semistructured interviews with a subsample. The results support the value of preservice teachers engaging in CBSL experiences, supplemented with discussions and activities about diversity, as a way to improve their self-efficacy beliefs regarding equitable science teaching and learning of all students.  相似文献

Abstract

The purpose of this study was to evaluate the effect of participation in a 3-day outdoor environmental education program on preservice teachers' attitudes toward self-efficacy—which is a teacher's belief that he or she can teach environmental education (EE) effectively—and on outcome expectancy—which is a teacher's estimation of his or her influence on student learning. Participants were a convenience sample of 72 preservice elementary teachers taking a science methodology course at a state university. Participants were divided into 2 groups for this modified pretest/2-posttest/control group study. The instrument for all 3 tests was Sia's (1992) Environmental Education Efficacy Belief Instrument. The authors used parametric t tests to compare group means. The results suggested that the preservice teachers' self-efficacy was high before the program and remained unchanged by their teaching experiences but dropped significantly approximately 7 weeks after teaching. The lack of change in self-efficacy from the teaching experience was attributed to the structured nature and success of the teaching experience, but the negative effect of time on self-efficacy was believed to have resulted from the preservice teachers reevaluation of their ability to teach as they learned more about teaching methodologies. In addition, there was no significant change in outcome expectancy as a result of participation in the program or over time (7 weeks).  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

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

ABSTRACT

This study used an experimental, pretest-posttest control group design to investigate whether participation in a large-scale inquiry project would improve primary teachers’ attitudes towards teaching science and towards conducting inquiry. The inquiry project positively affected several elements of teachers’ attitudes. Teachers felt less anxious about teaching science and felt less dependent on contextual factors compared to the control group. With regard to attitude towards conducting inquiry, teachers felt less anxious and more able to conduct an inquiry project. There were no effects on other attitude components, such as self-efficacy beliefs or relevance beliefs, or on self-reported science teaching behaviour. These results indicate that practitioner research may have a partially positive effect on teachers’ attitudes, but that it may not be sufficient to fully change primary teachers’ attitudes and their actual science teaching behaviour. In comparison, a previous study showed that attitude-focused professional development in science education has a more profound impact on primary teachers’ attitudes and science teaching behaviour. In our view, future interventions aiming to stimulate science teaching should combine both approaches, an explicit focus on attitude change together with familiarisation with inquiry, in order to improve primary teachers’ attitudes and classroom practices.  相似文献

Quality teacher evaluation is a complex subject, requiring complex methods that draw from multiple data sources (Peterson, 2000). Most importantly, preservice teacher evaluation should match teacher education objectives (Popham, 1993) and, ultimately, be used to inform teacher practices and reform educational programming (Darling-Hammond, 1990). The purpose of this study is to present an evaluation model that uses multiple data sources for a preservice teacher’s internship experience. This model is employed within a teacher education program at a large land-grant university; the multiple data sources match program objectives and draw parallels between preservice and inservice teacher evaluation tools at use in this particular state. The evaluation model incorporates two guiding objectives within this college of education’s mission statement—objectives that focus on performance and reflection. First, preservice teachers are educated to assume roles of leadership and service in classroom practice, and second, preservice teachers are taught to become reflective practitioners, The first objective is measured by using a research-based classroom observation rating form during the internship that closely resembles the tool used by the state-licensing department of education. The second program objective is measured through the use of portfolios. In addition to using the results from these instruments to advise preservice teachers regarding their professional growth, the data can also guide program development within the college and suggest programmatic reform, an often overlooked yet integral factor of personnel evaluation. Discussion of specific rating results per instrument and specific avenues for program development are presented.  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

In a mixed-methods study, the authors investigate teacher typologies of elementary teachers (N = 132) in the United States based on their reformed science teaching beliefs. Additionally, the identified teacher typologies were compared with respect to their science content knowledge, self-efficacy and epistemic beliefs. Results revealed three clusters of teachers with different combinations of teaching beliefs and practices. Comparative analysis indicated significant differences among teacher typologies with respect to their epistemic beliefs and teaching efficacy beliefs. Additionally, interview results enhanced the depth of understanding of participants' views for reformed science teaching and further highlighted differences in the typologies. Study implications are considered with regard to improving teacher quality and preservice teacher training.  相似文献

Self-efficacy beliefs that relate to teachers’ motivation and performance have been an important area of concern for preservice teacher education. Research suggests high-quality science coursework has the potential to shape preservice teachers’ science self-efficacy beliefs. However, there are few studies examining the relationship between science self-efficacy beliefs and science content knowledge. The purpose of this mixed methods study is to investigate changes in preservice teachers’ science self-efficacy beliefs and science content knowledge and the relationship between the two variables as they co-evolve in a specialized science content course. Results from pre- and post-course administrations of the Science Teaching Efficacy Belief Instrument-B (Bleicher, 2004) and a physical science concept test along with semi-structured interviews, classroom observations and artifacts served as data sources for the study. The 18 participants belonged to three groups representing low, medium and high initial levels of self-efficacy beliefs. A repeated measures multivariate analysis of variance design was used to test the significance of differences between the pre- and post-surveys across time. Results indicated statistically significant gains in participants’ science self-efficacy beliefs and science conceptual understandings. Additionally, a positive moderate relationship between gains in science conceptual understandings and gains in personal science teaching efficacy beliefs was found. Qualitative analysis of the participants’ responses indicated positive shifts in their science teacher self-image and they credited their experiences in the course as sources of new levels of confidence to teach science. The study includes implications for preservice teacher education programs, science teacher education, and research.  相似文献

This study explored how preservice teachers grew in their understanding of inquiry science through conducting an in-depth individual inquiry investigation in their science methods course. Elementary preservice teachers’ understanding about inquiry investigations, their attitudes towards the assignment, and their views towards using individual inquiry investigations in their own classrooms were studied through written reflections, science notebook writings, and researcher field notes. After conducting an out-of-class inquiry investigation based on their own questions and design, the preservice teachers demonstrated a variety of strengths in their understandings of inquiry-based teaching, their attitudes towards doing science, and their projected use of inquiry in their own classrooms. Weak areas included forming researchable questions and superficial experimental design.  相似文献

Teacher education programs have adopted preparing science teachers that teach science through inquiry as an important pedagogic agenda. However, their efforts have not met with much success. While traditional explanations for this failure focus largely on preservice science teachers’ knowledge, beliefs and conceptions regarding science and science teaching, this conceptual paper seeks to direct attention toward discursive practices surrounding inquiry science teaching in teacher education programs for understanding why most science teachers do not teach science through inquiry. The paper offers a theoretical framework centered on critical notions of subjection and performativity as a much needed perspective on making/becoming of science teachers through participation in discursive practices of science teacher education programs. It argues that research based on such perspectives have much potential to offer a deeper understanding of the difficult challenges teacher education programs face in preparing inquiry practicing science teachers.  相似文献
