Exploring Exemplary Elementary Teachers’ Conceptions and Implementation of Inquiry Science

This study was an exploration of the conceptions of inquiry science held by exemplary elementary teachers. The origins of these conceptions were explored in order to establish how best to improve elementary teachers’ understanding and implementation of inquiry science teaching. Four focus group sessions were held as well as classroom observations. Data were also collected through surveys and interviews. The six exemplary teachers in this study held ideas about inquiry as “finding things out” and all described themselves as having been children who explored and experimented with the world around them. The teachers provided information about successful classroom environments and attitudes that they use to achieve strong inquiry science learning. The teachers had a number of recommendations for helping other teachers become inquiry science teachers and suggestions for professional development for teachers are made based on these recommendations.     

The Progression of Prospective Teachers’ Conceptions of School Science Content

The purpose of the present work is to describe the progression in the conceptions of prospective primary teachers about school science content while they were participating in three teacher education courses following the same constructivist oriented strategy. The participants’ written output was analyzed in various categories—selection of content, types of content and their relationships, levels of complexity, and presentation of content to pupils. There was evidence for some progress in their conceptions of the content from a traditional view to another that we termed intermediate since it did not reach the vision that we consider to be the most complex. Finally, we present a General Itinerary of Progression on school content that could serve as a referent for initial teacher education.     

Pre-service Physics Teachers＇ Conceptions of Nature of Science

Understanding of NOS （nature of science） appears as a prerequisite of a scientifically literate person. Promoting adequate understanding of NOS in pre-service physics teachers is, therefore, an important task of science educators. Before doing that, science educators must have information concerning their pre-service teachers＇ conceptions of NOS. This study used the MOSQ （myths of science questionnaire） to explore 17 pre-service physics teachers＇ conceptions of NOS. Commonly, these pre-service teachers expressed misunderstandings about NOS with respect to： （1） the relationship between theory and law; （2） science as cumulative; （3） subjectivity in science; （4） the scientific method; and （5） the relationship between science and technology. Science educators should consider and utilize these common misunderstandings as a basis of curricular framework for further improving pre-service physics teachers＇ understanding of NOS.     

Teachers’ and Students’ Conceptions of Good Science Teaching

Capitalizing on the comments made by teachers on videos of exemplary science teaching, a video-based survey instrument on the topic of ‘Density’ was developed and used to investigate the conceptions of good science teaching held by 110 teachers and 4,024 year 7 students in Hong Kong. Six dimensions of good science teaching are identified from the 55-item questionnaire, namely, ‘focussing on science learning’, ‘facilitating students’ understanding’, ‘encouraging students’ involvement’, ‘creating conducive environment’, ‘encouraging active experimentation’ and ‘preparing students for exam (PSE)’. Significant gaps between teachers’ and students’ conceptions on certain dimensions have been revealed. The inconsistency on the dimension ‘PSE’ is particularly evident and possible reasons for the phenomenon are suggested. This study raises the important questions of how the gap can be addressed, and who is to change in order to close the gaps. Answers to these questions have huge implications for teacher education and teacher professional development.     

Preservice Teachers‘ Classroom Practice and Their Conceptions of the Nature of Science

The present article describes research carried out in Badajoz (Spain) with student teachers of Primary and Secondary science education. The preservice teachers conceptions of the nature of science were analyzeda and compared with their classroom practice when teaching a science lesson. The results indicated that there was no correspondence between the conceptions of the nature of science and the classroom practice. The implications of the research for science teacher education are dealt with.     

The Influence of Metacognitive Training on Preservice Elementary Teachers’ Conceptions of Nature of Science

This study assessed the influence of training in, and use of, metacognitive strategies on the development of prospective elementary teachers’ views of nature of science (NOS). Participants were 49 students (92% female) enrolled in two sections of an elementary science methods course. The sections were randomly assigned to an intervention group and a comparison group. Students in both groups were engaged with explicit‐reflective NOS instruction, which focused on the empirical, tentative, theory‐driven, inferential, and creative NOS. Additionally, students in the intervention group received instruction in, and used, three metacognitive strategies during their engagement with thinking about NOS. The Views of Nature of Science Questionnaire—Form C and the Metacognitive Awareness Inventory were respectively used to assess participants’ views of NOS and metacognitive awareness at the beginning and conclusion of the study. Data analyses indicated that significantly more students in the intervention group explicated more informed views of the target aspects of NOS. Moreover, these substantial changes were coupled with significantly increased Metacognitive Awareness Inventory scores for the intervention group participants. The results point to a relationship between improved metacognitive awareness and the development of informed understandings of NOS.     

Prospective Elementary Teachers’ Understanding of the Nature of Science and Perceptions of the Classroom Learning Environment

This study investigated prospective elementary teachers’ understandings of the nature of science and explored associations with their guided-inquiry science learning environment. Over 500 female students completed the Nature of Scientific Knowledge Survey (NSKS), although only four scales were analyzed–Creative, Testable, Amoral, and Unified. The learning environment was assessed using previously-validated and reliable scales from What Is Happening In this Class? (WIHIC) and the Science Laboratory Environment Inventory (SLEI). Analyses indicated moderate multiple correlations that were statistically significant (p?<?0.01) between Creative (R?=?0.22), Testable (R?=?0.29), and Unified (R?=?0.27), and a positive learning environment. Regression coefficients revealed that Open-Endedness was a significant independent predictor of students’ understanding of the role of creativity in science (β?=?0.16), while Cooperation, Open-Endedness, and Material Environment were linked with understanding the testable nature of science (β?=?0.10–0.12). Interview questions probed possible relationships between an improved understanding of the nature of science and elements of a positive classroom environment. Responses suggested that an appropriate level of open-endedness during investigations was very important as this helped students grapple with abstract nature of science concepts and shift their conceptions closer to a more realistic view of scientific practice.     

Experienced Teachers’ Strategies for Assessing Nature of Science Conceptions in the Elementary Classroom

This study explored the nature of science (NOS) assessments K-4 classroom teachers developed for measuring students’ understandings of NOS elements. We used the Views of Nature of Science Questionnaire-Form VNOS-D2 (Views of Nature of Science Elementary School Version 2) and interviews to verify that teachers’ conceptions of NOS were sufficient to enable them to teach and assess NOS. We collected copies of teachers’ action research designs, lesson plans, and assessment tools, conducted classroom observations and made field notes of their science instruction and assessments. We videotaped conversations at monthly workshops to note discussion surrounding teaching and assessing NOS in K-4 classrooms. We found that experienced teachers designed a variety of strategies for assessing NOS conceptions that differed by grade level.     

Exploring Natural and Social Scientists’ Views of Nature of Science

Science education researchers recently turned their attention to exploring views about nature of science (NOS). A large body of research indicates that both students and teachers have many naïve views about the NOS. Unfortunately, less attention has been directed at the issue of exploring the views of the scientists. Also, the little research in the literature generally took into consideration NOS views of only natural scientists. This study primarily proposes to explore the views of scientists in both the natural and social sciences regarding the seven target aspects of NOS. The second aim of the study is to find out the similarities and dissimilarities between the views of scientists who majored in social sciences and those who majored in natural sciences in terms of the target aspects of NOS. The sample was 69 scientists representing 5 scientific disciplines from natural and social sciences. Interviews were employed for obtaining data. The data were analyzed by means of cognitive maps. This study revealed that the scientists in the sample have neither completely informed views nor completely naïve views according to contemporary scientific understanding. Their views were a blend of the two in terms of almost all the target aspects of NOS. The views of the scientists in natural science and in social science were not substantially different. The scientists from both groups generally had similar viewpoints. This situation suggested that the scientists' views about NOS are not related to their scientific disciplines.     

Teaching Nature of Science to Preservice Science Teachers: A Phenomenographic Study of Chinese Teacher Educators’ Conceptions

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).

Exploring the Development of Preservice Science Teachers’ Views on the Nature of Science in Inquiry-Based Laboratory Instruction

The purpose of this study was to explore the effect of the inquiry-based and explicit–reflective laboratory instruction on preservice science teachers’ (PSTs) conceptions of the nature of science (NOS) aspects. This study was carried out during the Laboratory Application in Science II course. All 52 preservice elementary science teachers enrolled in the course consented to participate in the study; 37 were female and 15 were male, with a mean age of 22.8 years. All had the same science major background, and all of them were juniors. The course provided meaningful and practical inquiry-based experiences, as well as explicit and reflective instruction about NOS. Each week, a specific NOS aspect was targeted related to the inquiry-based laboratory investigation. The design of the study was qualitative and exploratory in nature. At the beginning of the study, the Views of Nature of Science Questionnaire Version B open-ended questionnaire was applied to explore PSTs’ NOS views. At the end of the semester, the same questionnaire was conducted to determine the impact of the explicit–reflective and inquiry-based laboratory instruction. The results showed that many PSTs improved their views of NOS in each element, although to different degrees.

The Progression of Prospective Primary Teachers’ Conceptions of the Methodology of Teaching

This article describes the evolution of prospective primary teachers’ conceptions of the methodology of teaching. Three categories were analyzed: the concept of activity, the organization of activities, and the concept of teaching resources. The study was conducted with five teams of prospective teachers, who were participating in teacher education courses of a constructivist orientation. The results showed very different itineraries in the processes of change, and the presence of two major obstacles—the belief that teaching is the direct cause of learning, and epistemological absolutism. The study allows us to deduce some implications for initial teacher education.     

Minority Preservice Teachers’ Conceptions of Teaching Science: Sources of Science Teaching Strategies

This study explores five minority preservice teachers’ conceptions of teaching science and identifies the sources of their strategies for helping students learn science. Perspectives from the literature on conceptions of teaching science and on the role constructs used to describe and distinguish minority preservice teachers from their mainstream White peers served as the framework to identify minority preservice teachers’ instructional ideas, meanings, and actions for teaching science. Data included drawings, narratives, observations and self-review reports of microteaching, and interviews. A thematic analysis of data revealed that the minority preservice teachers’ conceptions of teaching science were a specific set of beliefs-driven instructional ideas about how science content is linked to home experiences, students’ ideas, hands-on activities, about how science teaching must include group work and not be based solely on textbooks, and about how learning science involves the concept of all students can learn science, and acknowledging and respecting students’ ideas about science. Implications for teacher educators include the need to establish supportive environments within methods courses for minority preservice teachers to express their K-12 experiences and acknowledge and examine how these experiences shape their conceptions of teaching science, and to recognize that minority preservice teachers’ conceptions of teaching science reveal the multiple ways through which they see and envision science instruction.     

Changing Preservice Science Teachers’ Views of Nature of Science: Why Some Conceptions May be More Easily Altered than Others

The purpose of this study was to assess preservice teachers’ views of Nature of Science (NOS), identify aspects that were challenging for conceptual change, and explore reasons why. This study particularly focused on why and how some concepts of NOS may be more easily altered than others. Fourteen preservice science teachers enrolled in a NOS and Science Inquiry course participated in this study. Data were collected by using a pre/post format with the Views of Nature of Science questionnaire (VNOS-270), the Views of Scientific Inquiry questionnaire (VOSI-270), follow-up interviews, and classroom artifacts. The results indicated that most students initially held naïve views about certain aspects of NOS like tentativeness and subjectivity. By the end of the semester, almost all students dramatically improved their understanding about almost all aspects of NOS. However, several students still struggled with certain aspects like the differences between scientific theory and law, tentativeness, and socio-cultural embeddedness. Results suggested that instructional, motivational, and socio-cultural factors may influence if and how students changed their views about targeted NOS aspects. Students thought that classroom activities, discussions, and readings were most helpful to improve their views about NOS. The findings from the research have the potential to translate as practical advice for teachers, science educators, and future researchers.
