Adapted primary literature (APL) refers to an educational genre specifically designed to enable the use of research articles for learning biology in high school. The present investigation focuses on the paedagogical content knowledge (PCK) of four high‐school biology teachers who enacted an APL‐based curriculum in biotechnology. Using a constructivist qualitative research approach, we analysed those teachers' aims and beliefs, the instructional strategies they used during the enactment of the curriculum, as well as the outcomes of the enactment as perceived by the teachers and their students, and as reflected in the class observations. Some of the teachers' strategies applied during the enactment, such as the conversational model, were specifically designed for teaching APL‐based curricula. We found that the instructional strategies applied for the adapted articles were associated with cognitive and affective engagement, active learning, inquiry thinking, and understanding of the nature of science. Suitable teacher PCK promoted learning by inquiry in addition to learning on inquiry. Students' challenges were mainly linked to the comprehension of complex, multi‐stage, biotechnological processes and methods that are abundant throughout the curriculum and required the use of previous knowledge in new contexts. A complex interaction of factors, namely teachers' PCK, the APL genre, and the biotechnology content of the curriculum, shaped the instructional strategies of the new curriculum and the outcomes of its enactment  相似文献

Understanding the interaction between internally constructed and externally imposed aspects of the teaching context may be the missing link between calls for school reform and teachers' interpretation and implementation of that reform. Although the context of the local school culture has a profound impact on teachers, there are other external forces that are specifically aimed at influencing teachers' pedagogical and curricular decisions. These externally imposed aspects of context include some of the existing tools of reform, such as national standards, mandated state core curricula, and related criterion‐referenced testing. However, little is known about how these reform tools impact teachers' thinking about science and science teaching or how teachers respond to such tools. This study examined the interactions between individual teachers' beliefs about teaching and learning science in elementary school and the tools of reform that are imposed upon them. Comparative case studies were conducted in which two elementary teachers' science instruction, teaching context, and related beliefs were examined, described, and analyzed. In this study, the teachers' fundamental beliefs about science and what it means to teach and learn science influenced their interpretations of the sometimes contradictory messages of reform as they are represented in the standards, mandated curriculum, and end‐of‐level tests. Suggestions about what these findings mean for needed aspects of teacher professional development are offered. © 2007 Wiley Periodicals, Inc. J Res Sci Teach 44: 396–423, 2007  相似文献

New reform documents underscore the importance of integrating science practices into the learning of science. This integration requires sophisticated teaching that does not often happen. Educative curriculum materials – materials explicitly designed to support teacher and student learning – have been posited as a way to support teachers to achieve these ambitious goals, yet little is known about how elementary teachers actually use educative curriculum materials to support student engagement in science practices. To address this gap, this study investigated how five upper elementary teachers supported students to engage in science practices during an enactment of two curriculum units. Three of the teachers had units enhanced with educative features, informed by current research and reforms, while two of the teachers had units without these features. The teachers varied in how they supported students in the science practices of justifying predictions, constructing evidence-based claims, recording observations, and planning investigations. For example, some of the teachers with the educative features supported students in constructing evidence-based claims and justifying predictions in ways called for by the educative features. Implications for curriculum developers and teacher educators are discussed based on the patterns found in the teachers’ use of the educative curriculum materials.  相似文献

Research Findings: This study examined the consistency between early childhood teachers' self-reported curriculum beliefs and observations of their actual interactive behaviors with children in classrooms. Also tested was the hypothesized moderation by teacher and classroom characteristics of the association between beliefs and practices. A total of 58 preschool teachers completed a survey describing their professional backgrounds and curriculum beliefs. Their classroom practices were observed using a newly developed instrument that documented teacher interactions with children. Most teachers in this sample strongly endorsed child-initiated learning beliefs, although their beliefs about teacher-directed learning varied considerably. The most frequently observed teacher behaviors in the classroom were giving directions to children, responding to children's initiations, and engaging in non-interactive classroom management activities. Overall, teachers' curriculum beliefs and observed classroom practices were weakly correlated. However, there were moderation effects. Stronger congruence between teacher-directed learning beliefs and observed teaching behaviors was found among teachers who had more professional training and more years of teaching experience. Practice or Policy: These results support the importance of early childhood teacher professional development. They suggest that teacher preparation and professional development programs should focus on the intellectual transformation between teacher knowledge and teacher practice, promoting both aspects of development.  相似文献

This paper describes Ecuadorian in-service teachers and their science teaching practices in public primary schools. We wanted to find out to what extent teachers implement inquiry activities in science teaching, the level of support they provide, and what type of inquiry they implement. Four questionnaires applied to 173 teachers resulted in the identification of high context beliefs and moderately high self-efficacy beliefs. Teachers declared to implement activities mostly to develop understanding of the material, as contrast to actual manipulation of data and/or coming to conclusions. They adopt rather a strictly guided approach in contrast to giving autonomy to learners to work on their own. Finally, teachers keep control with regard to question formulation and choice in solution procedures, which constrains the development of real inquiry. When comparing teacher beliefs, we found that teachers' context beliefs make a difference in the level of support that teachers provide to their students. Teachers with lower context beliefs ask students to perform inquiry activities on their own to a lesser extent when compared with teachers with higher context beliefs. This implies that further research on the implementation of inquiry in science teaching should take into account teachers' differences in their context beliefs. We also found out that the use of high or low support in inquiry activities remained the same for teachers with either higher or lower self-efficacy beliefs.  相似文献

This study explored practicing elementary school teacher’s conceptions of teaching in ways that foster inquiry-based learning in the science curriculum (inquiry teaching). The advocacy for inquiry-based learning in contemporary curricula assumes the principle that students learn in their own way by drawing on direct experience fostered by the teacher. That students should be able to discover answers themselves through active engagement with new experiences was central to the thinking of eminent educators such as Pestalozzi, Dewey and Montessori. However, even after many years of research and practice, inquiry learning as a referent for teaching still struggles to find expression in the average teachers’ pedagogy. This study drew on interview data from 20 elementary teachers. A phenomenographic analysis revealed three conceptions of teaching for inquiry learning in science in the elementary years of schooling: (a) The Experience-centered conception where teachers focused on providing interesting sensory experiences to students; (b) The Problem-centered conception where teachers focused on engaging students with challenging problems; and (c) The Question-centered conception where teachers focused on helping students to ask and answer their own questions. Understanding teachers’ conceptions has implications for both the enactment of inquiry teaching in the classroom as well as the uptake of new teaching behaviors during professional development, with enhanced outcomes for engaging students in Science.  相似文献

This article reports the outcomes of a project in which teachers' sought to develop their ability to use instructional practices associated with argumentation in the teaching of science—in particular, the use of more dialogic approach based on small group work and the consideration of ideas, evidence, and argument. The project worked with four secondary school science departments over 2 years with the aim of developing a more dialogic approach to the teaching of science as a common instructional practice within the school. To achieve this goal, two lead teachers in each school worked to improve the use of argumentation as an instructional practice by embedding activities in the school science curriculum and to develop their colleague's expertise across the curriculum for 11‐ to 16‐year‐old students. This research sought to identify: (a) whether such an approach using minimal support and professional development could lead to measurable difference in student outcomes, and (b) what changes in teachers' practice were achieved (reported elsewhere). To assess the effects on student learning and engagement, data were collected of students' conceptual understanding, reasoning, and attitudes toward science from both the experimental schools and a comparison sample using a set of standard instruments. Results show that few significant changes were found in students compared to the comparison sample. In this article, we report the findings and discuss what we argue are salient implications for teacher professional development and teacher learning. © 2013 Wiley Periodicals, Inc.

The goal of this research is to identify science teachers' beliefs and conceptions that play an important role in shaping their understandings of and attempts to enact inclusive science teaching practices. We examined the work products, both informal (online discussions, email exchanges) and formal (papers, unit plans, peer reviews), of 14 teachers enrolled in a master's degree course focused on diversity in science teaching and learning. These emerging understandings were member-checked via a series of interviews with a subset of these teachers. Our analysis was conducted in two stages: (1) describing the difficulties the teachers identified for themselves in their attempts to teach science to a wide range of students in their classes and (2) analyzing these self-identified barriers for underlying beliefs and conceptions that serve to prohibit or allow for the teachers' understanding and enactment of equitable science instruction. The teachers' self-identified barriers were grouped into three categories: students, broader social infrastructure, and self. The more fundamental barriers identified included teacher beliefs about the ethnocentrism of the mainstream, essentialism/individualism, and beliefs about the meritocracy of schooling. The implications of these hurdles for science teacher education are discussed.  相似文献

The present study was designed to identify and characterize the major factors that influence entering science teacher candidates’ preferences for different types of instructional activities, and to analyze what these factors suggest about teacher candidates’ orientations towards science teaching. The study involved prospective teachers enrolled in the introductory science teaching course in an undergraduate science teacher preparation program. Our analysis was based on data collected using a teaching and learning beliefs questionnaire, together with structured interviews. Our results indicate that entering science teacher candidates have strong preferences for a few activity types. The most influential factors driving entering science teacher candidates’ selections were the potential of the instructional activities to motivate students, be relevant to students’ personal lives, result in transfer of skills to non‐science situations, actively involve students in goal‐directed learning, and implement curriculum that represents what students need to know. This set of influencing factors suggests that entering science teacher candidates’ orientations towards teaching are likely driven by one or more of these three central teaching goals: (1) motivating students, (2) developing science process skills, and (3) engaging students in structured science activities. These goals, and the associated beliefs about students, teaching, and learning, can be expected to favor the development or enactment of three major orientations towards teaching in this population of future science teachers: “motivating students,” “process,” and “activity‐driven.”  相似文献

This study explored how teachers' prior experiences, beliefs about knowledge, and schooling contexts collectively influenced their ability to implement classroom curricula that were culturally relevant to their students and that were constructivist in orientation. Using a case study design, this paper presents a 4-year longitudinal study of Dan, a second-career teacher who entered teaching after being a field scientist for an international corporation for 6 years, and Amy, who became an English teacher after being a floral designer for 10 years. Using the theoretical perspective of world view as described by Shuell (1992) [Teaching and Teacher Education, 8(1), 83–90] and Cobern (1993) [The practice of constructivism in science education, Washington, DC: American Association for the Advancement of Science], I explored the professional development of Dan and Amy, who differed in their world views. Specifically, I examined how their world views gave shape to their classroom learning environments, including their classroom curricula and their interactions with students during their initial years of becoming teachers. Multiple sources of data were gathered throughout the 4 year study from formal and informal interviews, observations of classroom teaching, stimulated recall interviews, and biographical interviews. Using the constant comparative method of data analysis, salient themes emerged from the data, including beliefs about teaching content knowledge, beliefs about learners, and influences on classroom curriculum. Implications for creating constructivist and culturally relevant classroom curricula are discussed.  相似文献

This study identifies proficiency levels in pre-service physics teachers' pedagogical content knowledge (PCK) and reveals how teacher education can promote transitions into higher proficiency. Teacher education plays a fundamental role in supporting pre-service teachers' PCK development. Proficiency levels are a powerful source when evaluating this PCK development because they characterize what learners are likely to be able to know on a specific level. Previous research has presented a model of proficiency levels in pre-service physics teachers' PCK; however, evidence for the model's validity is still lacking. According to the Refined Consensus Model of PCK, factors such as teachers' content knowledge (CK), their teaching experience, and their beliefs about teaching and learning science promote PCK development. Thus, understanding how and when pre-service physics teachers' CK, teaching experience, and beliefs contribute to their proficiency can bring insights into how teacher education can promote PCK development. To address this issue, N = 427 observations of pre-service physics teachers were analyzed. Utilizing the scale anchoring procedure, four different proficiency levels in pre-service physics teachers' PCK were identified. Analyzing these proficiency levels showed that lower levels can be characterized as remembering content-unspecific knowledge, whereas higher levels encompass content-specific strategies to structure and elaborate lessons. Additionally, logistic regression models revealed that pre-service physics teachers' CK is crucial for an increase in PCK proficiency. However, transitions into higher levels of PCK additionally require teaching experience and adequate beliefs about teaching and learning. Thus, our proficiency levels can be used to bring insights into how proficiency in PCK can be supported during teacher education. For example, teacher education should provide courses focusing on the science curriculum and the assessment of student learning to promote pre-service physics teachers' progression in PCK.  相似文献

Fostering students' spatial thinking skills holds great promise for improving Science, Technology, Engineering, and Mathematics (STEM) education. Recent efforts have focused on the development of classroom interventions to build students' spatial skills, yet these interventions will be implemented by teachers, and their beliefs and perceptions about spatial thinking influence the effectiveness of such interventions. However, our understanding of elementary school teachers' beliefs and perceptions around spatial thinking and STEM is in its infancy. Thus, we created novel measures to survey elementary teachers' anxiety in solving spatial problems, beliefs in the importance of spatial thinking skills for students' academic success, and self-efficacy in cultivating students' spatial skills during science instruction. All measures exhibited high internal consistency and showed that elementary teachers experience low anxiety when solving spatial problems and feel strongly that their skills can improve with practice. Teachers were able to identify educational problems that rely on spatial problem-solving and believed that spatial skills are more important for older compared to younger students. Despite reporting high efficacy in their general teaching and science teaching, teachers reported significantly lower efficacy in their capacities to cultivate students' spatial skills during science instruction. Results were fairly consistent across teacher characteristics (e.g., years of experience and teaching role as generalist or specialist) with the exception that only years of teaching science was related to teachers' efficacy in cultivating students' spatial thinking skills during science instruction. Results are discussed within the broader context of teacher beliefs, self-efficacy, and implications for professional development research.  相似文献

This article is a study of a South African teacher educator's interpretations and approaches to implementing a constructivist approach to teaching. It examines his beliefs about teaching physical science to prospective teachers as it relates to his aligning his teaching with the new reform: outcomes-based education. The goals of the reform include emphasis on cooperative learning, a student-centered approach, and focus on teaching for conceptual understanding. Through observations, interviews, and documents (assignments for students, graded group assignments, and course outlines), I examined this teacher educator's interpretations and approaches to implementing constructivist curriculum and his understanding of the reform. The findings show that without confronting teachers' beliefs about teaching and learning, providing clear meaning of reforms, and facilitating in-depth professional development, the interpretation and implementation of reforms will be hindered.  相似文献

Inquiry-based curricula are an essential tool for reforming science education yet the role of the teacher is often overlooked in terms of the impact of the curriculum on student achievement. Our research focuses on 22 teachers’ use of a year-long high school urban ecology curriculum and how teachers’ self-efficacy, instructional practices, curricular enactments and previous experience impacted student learning. Data sources included teacher belief surveys, teacher enactment surveys, a student multiple-choice assessment focused on defining and identifying science concepts and a student open-ended assessment focused on scientific inquiry. Results from the two hierarchical linear models indicate that there was significant variation between teachers in terms of student achievement. For the multiple-choice assessment, teachers who spent a larger percentage of time on group work and a smaller percentage of time lecturing had greater student learning. For the open-ended assessment, teachers who reported a higher frequency of students engaging in argument and sharing ideas had greater student learning while teachers who adapted the curriculum more had lower student learning. These results suggest the importance of supporting the active role of students in instruction, emphasising argumentation, and considering the types of adaptations teachers make to curriculum.  相似文献

Teachers' motivational beliefs—i.e., teachers' self-efficacy and felt responsibility for educational outcomes—can shape their professional decision-making and approaches to teaching. However, theorized associations with student outcomes remain elusive. In a multi-level analysis with 96 Swiss vocational teachers and their 1300 students, we examined the interrelations between teachers' self-efficacy, responsibility, teacher- and student-reported autonomy-supportive versus psychologically controlling teaching, and student motivation (emotional, behavioral, and cognitive engagement). Teachers' motivational beliefs predicted their endorsement of autonomy-supportive teaching, which in turn predicted student-reported autonomy support. Student-reported autonomy support was a powerful predictor of student engagement. Teachers’ motivational beliefs did not predict student-reported instructional practices and engagement directly, and indirect effects via teacher- and student-reported autonomy support were small. Teacher- and student-reported controlling practices were not significantly correlated. The degree of (mis)alignment of teacher- and student-reported instructional practices is a key ingredient in understanding the often missing link between teacher motivation and student outcomes.  相似文献

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

This study unveils the stories of 3 public school elementary teachers from the USA who reflected on their beliefs about science education reform, and implementation of the reform in their classroom teaching, in response to state recommendations for change in science education. The teachers' stories show how various factors assisted or impeded the implementations of reform in their teaching, the various challenges related to their grade-level teaching, and the teachers' personal struggles to make sense of reform recommendations. Within each case study, we describe 4 common themes from the teachers' interviews. These themes are related to teachers' science teaching strategies, their science teaching efficacy beliefs about adopting reform, the types of science learning outcomes teachers target, and the types of teaching resources available to them. Implications for teacher education and practice are discussed in relationship with study findings.  相似文献
