The Interpretation and Implementation of Reform: A Case of Simon

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.     

Teaching a Biotechnology Curriculum Based on Adapted Primary Literature

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

Learning by doing? Prospective elementary teachers' developing understandings of scientific inquiry and science teaching and learning

This study examined prospective elementary teachers' learning about scientific inquiry in the context of an innovative life science course. Research questions included: (1) What do prospective elementary teachers learn about scientific inquiry within the context of the course? and (2) In what ways do their experiences engaging in science investigations and teaching inquiry‐oriented science influence prospective elementary teachers' understanding of science and science learning and teaching? Eleven prospective elementary teachers participated in this qualitative, multi‐participant case study. Constant comparative analysis strategies attempted to build abstractions and explanations across participants around the constructs of the study. Findings suggest that engaging in scientific inquiry supported the development more appropriate understandings of science and scientific inquiry, and that prospective teachers became more accepting of approaches to teaching science that encourage children's questions about science phenomena. Implications include careful consideration of learning experiences crafted for prospective elementary teachers to support the development of robust subject matter knowledge.     

Success in Science Learning and Preservice Science Teaching Self-Efficacy

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.     

The Conceptions of In-service and Prospective Primary School Teachers About the Teaching and Learning of Science

A study was performed to describe and analyze the conceptions about teaching and learning science held by different samples of teachers in Spain. The responses of 265 teachers (107 prospective teachers and 158 active teachers) to items from the Inventory of Scientific and Pedagogical Beliefs (Porlán, 1989) were subjected to multifactorial analysis. The results showed various tendencies in how the teaching/learning process is viewed, ranging from a predominant view based on the transmission-reception of knowledge to a minority constructivist view. There was a greater diversity of viewpoints among the in-service teachers than among the prospective teachers. In both samples, the most representative tendency was learning as appropriation of meanings, followed by a technical view of teaching among the prospective teachers and a more traditional view among the in-service teachers. Finally, some implications for teacher education are discussed.     

Metaphors as blueprints of thinking about teaching and learning

This study analyses the metaphorical conceptions of learning based on the reflections of 50 experienced teachers in an evening course on instructional psychology. The metaphors were achieved by collaboration in small groups. “Co-reflection” of group members was well suited to promote metaphorical reconstructions of teachers’ tacit theories about learning. The results show that the majority of these teachers shares traditional metaphors depicting teaching and learning as transmission of knowledge, followed by a smaller group of teachers expressing constructivist metaphors. Only a minority seems to conceive of teaching and learning as a social process. These results are compared with metaphors formulated by 38 prospective teachers without classroom experience participating in a course on curriculum design. In further collaborations these metaphors should serve as stepping stones to broader and more profound conceptions of the nature of teaching and learning.     

Russian/US comparison using the expert science teaching educational evaluation model (ESTEEM)

A small group of Russian teachers who were interested in adopting aspects of the US science educational reform movement, participated in a constructivist science teaching project. Baseline data from translated classroom observations were scored using the science classroom observation rubric from the expert science teaching educational evaluation model (ESTEEM) and compared with a traditional (teacher centered) group of US science teachers and a group of US constructivist (student centered) science teachers. The purpose of the research is to investigate how Russian teachers who were beginning a US science education reform project compared with two US groups of science teachers, a traditional and a reform group. Analysis of variance was used to analyse the total rubric score and four categories for the Russian/traditional US and the Russian/constructivist US studies in order to examine closely the traditional and the constructivist teaching practises. In the first study US traditional teachers were statistically higher on 'facilitating the learning process' and 'context-specific pedagogy'. Russian teachers were higher on the 'content' category. In the second study the experienced constructivist US teachers were statistically higher on all four categories and the total rubric score. The educational culture of both countries is very traditional. However, the reform movement in science education has changed some US teachers, and is in the process of changing some Russian teachers. Both countries are working on the reform process. The results of this study provide baseline information on a small group of Russian teachers, who have chosen to be a part of the ideas contained in the US science education reform movement. The study also promotes the mutual understanding of both cultures among teachers, administrators, and researchers, which should ultimately form a bond for working together on common educational issues.

Enhancing pedagogical content knowledge in elementary science

In this study, five elementary teachers and a university researcher developed and implemented problem‐based learning (PBL) experiences in the context of science teaching and learning. Collaborative inquiry was adopted as a methodology, while a variety of qualitative methods were used to examine the engagement and development of teachers’ pedagogical content knowledge (PCK). A PCK model is used as a framework to examine teachers’ professional knowledge growth in areas such as orientations to teaching science, knowledge of science curriculum, knowledge of students’ understanding of science, knowledge of assessment, and knowledge of instructional strategies. Implications for how teachers may be supported when adopting instructional innovations are discussed.     

The effect of a training course based on constructivism on student teachers' perceptions of the teaching/learning process

This study investigates the effect of a training course, based on constructivism, on the student teachers' perceptions of teaching, learning and the roles of teachers and students in the teaching‐learning process. A sample of 188 student teachers (92 of them in the experimental group and 96 in the control group) from the Hashemite University were subjected to a pre‐test that was developed and validated for the purpose of the study, and the experimental group was then trained using a four‐step training course based on constructivist ideas. Results showed that the two groups' perceptions were not consistent with constructivist ideas before the training took place, but after training, there were significant differences between the two groups' perceptions about the four areas. Also, there were significant differences between the constructivist perceptions of males and females, with females' perceptions being more consistent with constructivist ideas than males. The study concluded with recommendations concerning the introduction of constructivist ideas in educational courses that are designed to prepare student teachers for science teaching, and further research to examine the effect of this course on the student teachers' practices in the classrooms.     

Enhancing Teachers’ Application of Inquiry‐Based Strategies Using a Constructivist Sociocultural Professional Development Model

This two‐year school‐wide initiative to improve teachers’ pedagogical skills in inquiry‐based science instruction using a constructivist sociocultural professional development model involved 30 elementary teachers from one school, three university faculty, and two central office content supervisors. Research was conducted for investigating the impact of the professional development activities on teachers’ practices, documenting changes in their philosophies, instruction, and the learning environment. This report includes teachers’ accounts of philosophical as well as instructional changes and how these changes shaped the learning environment. For the teachers in this study, examining their teaching practices in learner‐centered collaborative group settings encouraged them to critically analyze their instructional practices, challenging their preconceived ideas on inquiry‐based strategies. Additionally, other factors affecting teachers’ understanding and use of inquiry‐based strategies were highlighted, such as self‐efficacy beliefs, prior experiences as students in science classrooms, teacher preparation programs, and expectations due to federal, state, and local mandates. These factors were discussed and reconciled, as they constructed new understandings and adapted their strategies to become more student‐centered and inquiry‐based.     

Utilizing Science Philosophy Statements to Facilitate K-3 Teacher Candidates’ Development of Inquiry-based Science Practice

This study utilized pre-service teachers’ philosophy statements to connect their beliefs for science teaching with inquiry-based constructivist classroom practice. The major findings of this study suggested that before entering the classroom prospective teachers are strongly aligned with inquiry-based, constructivist-based theories, and describe teaching science as a process approach. However, after entering public classrooms the teacher candidates often abandoned those notions of constructivist, inquiry-based science in favor of a more traditional approach to science instruction. This study addresses a method to engage prospective teachers in designing inquiry-based science pedagogy as well as developing their professional pedagogical confidence.     

Teachers' Adequacy of Subject Knowledge in Primary Science: Assessing constructivist approaches from a sociocultural perspective

In recent years, increasing emphasis has come to be placed, both by researchers and by policy‐makers, on the adequacy of primary teachers’ subject knowledge of science. Within research, this emphasis has been linked to the rise of constructivist ideas about the significance of establishing children’s prior conceptions of scientific concepts for effective teaching. In this article I examine two constructivist approaches to teachers’ adequacy of subject knowledge within UK research on primary science education. In each case I provide a critique of the assumptions they make about the nature of knowledge and how it develops. I do this from a sociocultural perspective, which views knowledge and learning as necessarily situated within communities of practice. My aim is to assess the implications of this perspective for understanding teachers’ adequacy of subject knowledge.     

Changes in science classrooms after experiencing an international professional staff development program

This professional development program was designed to prepare science teachers to be more student-centered and to implement newer goals for science instruction. These goals are to improve science teaching in ways that promote broader and longer-lasting learning. Secondary school science teachers in Korea are expected to follow a rigid national curriculum with large classes - often with more than 50 students. This study focuses on feedback and follow-up interaction with teacher participants who were enrolled in a month-long workshop in the U.S. before returning to Korea to implement the new ideas. Assistance was offered to help teachers develop teaching modules which were more constructivist while also assisting with assessment efforts that provided further evidence of use of the new teaching practices and their effect on student learning. Student mastery of concepts and improvement in student creativity were two aspects of the summer workshop experiences and these were evaluated to illustrate workshop effects on teacher participants in their actual classrooms.

Curriculum design for inquiry: Preservice elementary teachers' mobilization and adaptation of science curriculum materials

Curriculum materials are crucial tools with which teachers engage students in science as inquiry. In order to use curriculum materials effectively, however, teachers must develop a robust capacity for pedagogical design, or the ability to mobilize a variety of personal and curricular resources to promote student learning. The purpose of this study was to develop a better understanding of the ways in which preservice elementary teachers mobilize and adapt existing science curriculum materials to plan inquiry‐oriented science lessons. Using quantitative methods, we investigated preservice teachers' curriculum design decision‐making and how their decisions influenced the inquiry orientations of their planned science lessons. Findings indicate that preservice elementary teachers were able to accurately assess how inquiry‐based existing curriculum materials are and to adapt them to make them more inquiry‐based. However, the inquiry orientations of their planned lessons were in large part determined by how inquiry‐oriented curriculum materials they used to plan their lessons were to begin with. These findings have important implications for the design of teacher education experiences that foster preservice elementary teachers' pedagogical design capacities for inquiry, as well as the development of inquiry‐based science curriculum materials that support preservice and beginning elementary teachers to engage in effective science teaching practice. © 2009 Wiley Periodicals, Inc.

Knowing and teaching science: the constructivist paradox

This paper addresses the parallel between the changes in students' and teachers' learning advocated by constructivist science educators. It begins with a summary of the epistemology of constructivism and uses a vignette drawn from a set of case studies to explore the impact of a constructivist science in‐service programme on an experienced and formal elementary science teacher. Judged by constructivist standards, the teacher described in the vignette makes very little progress. The irony of applying a constructivist critique to his work, however, is that it fails to treat the teachers' imperfect knowledge of teaching with the same respect as constructivists treat students' imperfect learning of science. The remainder of the paper explores this constructivist paradox, and suggests that‐like students' knowledge of science‐teachers' knowledge of constructivist science teaching is likely to grow through slow and gradual re‐formation of their established understanding of classroom theory and practice.     

BOOK REVIEW

This paper describes an investigation in Korea of the extent to which a new general science curriculum, reflecting a constructivist view, has influenced the classroom learning environment in grade 10 science. The Constructivist Learning Environment Survey (CLES) was selected for the investigation and translated into Korean. Other objectives of this study were to determine whether the Korean version of the CLES is valid and reliable, differences between students’ perceptions of their actual and preferred learning environment and associations between students’ perceptions of the constructivist learning environment and their attitude to science. The Korean‐language version of the CLES was found to be valid and reliable and grade 10 students did perceive a more constructivist learning environment than grade 11 students who had not been exposed to the new curriculum. This suggested that efforts of curriculum reform had produced some positive effects. Students tended to prefer a more positive environment than what was perceived to be present and statistically significant relationships were found between classroom environment and student attitudes. These relationships suggest that favourable student attitudes could be promoted in classes where students perceive more personal relevance, share control with their teachers and negotiate their learning.     

Challenging Prospective Computer Engineers to Design Educational Software by Engaging Them in a Constructivist Learning Environment

This study focuses on the development of prospective computer engineers' knowledge of educational software design through their involvement in a constructivist learning environment emphasizing project based learning. Within this environment prospective computer engineers (PCE) adopted a variety of roles namely: learners, teachers, users, designers, implementers and evaluators of educational software dealing with concepts of computer science while also taking into account theoretical educational considerations regarding constructivism and social views of knowledge construction. The analysis of the data shows that PCE frequently start by considering traditional behavioristic views regarding teaching and learning as well as regarding the design of educational software. The PCE progressed to accept more constructivist views regarding teaching and learning as well as to designing educational software by communicating their knowledge with their colleagues and the teacher in the project based context. PCE also progressed through the evaluation of the educational software using real classrooms. By exploiting the given feedback, PCE improved the quality of software specifications.     

STEM Integration in Middle School Life Science: Student Learning and Attitudes

In many countries around the world, there has been an increasing emphasis on improving science education. Recent reform efforts in the USA call for teachers to integrate scientific and engineering practices into science teaching; for example, science teachers are asked to provide learning experiences for students that apply crosscutting concepts (e.g., patterns, scale) and increase understanding of disciplinary core ideas (e.g., physical science, earth science). Engineering practices and engineering design are essential elements of this new vision of science teaching and learning. This paper presents a research study that evaluates the effects of an engineering design-based science curriculum on student learning and attitudes. Three middle school life science teachers and 275 seventh grade students participated in the study. Content assessments and attitude surveys were administered before and after the implementation of the curriculum unit. Statewide mathematics test proficiency scores were included in the data analysis as well. Results provide evidence of the positive effects of implementing the engineering design-based science unit on student attitudes and learning.
