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.     

Elementary Teachers’ Perception of Language Issues in Science Classrooms

Although the importance of language in science learning has been widely recognized by researchers, there is limited research on how science teachers perceive the roles that language plays in science classrooms. As part of an intervention design project that aimed to enhance teachers’ capacity to address the language demands of science, interview data (N = 9) were collected to understand teachers’ perceptions and experiences with a wide range of issues related to language use in science classrooms. Adopting an interpretive approach to qualitative data, the analysis revealed that the teachers perceive a wide range of student difficulties related to language use in science classrooms, especially to the use of specialized terms and writing. Although the teachers are keenly aware of how language can be a barrier to learning science, they are less certain as to what students need to know about the language of science in order to master it. The findings suggested professional support that highlights the distinctive language demands of science and how these demands differ from other subject areas could be useful to these elementary school teachers.     

Students’ Perceptions of Their Science Teachers’ Pedagogical Content Knowledge

Pedagogical content knowledge (PCK) is a type of teacher knowledge to be developed by a teacher. PCK is said to contribute to effective teaching. Most studies investigated the development of PCK and its influence on students’ learning from the teachers’ perspectives. Only a limited number of studies have investigated the components of science teachers’ PCK that helped students’ learning from the perspective of students. Thus, it is the aim of this study to investigate the level of science teachers’ PCK from students’ perspective, in particular whether or not students of different achieving ability had different views of teachers’ PCK in assisting their learning and understanding. Based on the PCK research literature, six components of PCK have been identified, which were as follows: (1) subject matter knowledge, (2) knowledge of teaching strategies, (3) knowledge of concept representation, (4) knowledge of teaching context, (5) knowledge of students, and (6) knowledge of assessment in learning science. A questionnaire consisting of 56 items on a five-point Likert-type scale were used for data collection from 316 Form Four students (16 years old). One-way analysis of variance revealed that the differences in science teachers’ PCK identified by students of different achieving abilities were statistically significant. Overall, students of various academic achieving abilities considered all the components of PCK as important. The low-achieving students viewed all the components of PCK as being less important compared to the high and moderate achievers. In particular, low-achieving students do not view ‘knowledge of concept representation’ as important for effective teaching. They valued the fact that teachers should be alert to their needs, such as being sensitive to students’ reactions and preparing additional learning materials. This study has revealed that PCK of science teachers should be different for high and low-achieving students and knowledge of students’ understanding plays a critical role in shaping teachers PCK.     

Supporting Science Teachers in Alignment with State Curriculum Standards through Professional Development: Teachers’ Preparedness, Expectations and Their Fulfillment

Since A Nation at Risk was released in the 1980s, standards-based reform has been the most dominant trend in American educational policy, and the No Child Left Behind Act pushed the trend further by requiring states to develop rigorous curriculum standards. Though much has been said about these new standards, less has been said about whether or how well professional development helps teachers link their instruction to these standards. This study examined the impact of a professional development program for K-12 science teachers in helping teachers meet state curriculum standards. Seventy-five science teachers in Michigan participated in a 2-week summer workshop that used Problem-Based Learning for improving teachers’ content knowledge and pedagogical content knowledge. Researchers surveyed participating teachers about the change of teachers’ preparedness for standards-based teaching, their expectations to meet state curriculum standards, and whether their expectations were met. In addition, the usefulness of workshop activities was examined. Data analysis showed that to align teaching with state curriculum standards, participating teachers expected to learn instructional strategies and enhance science content knowledge through professional development, and by and large their expectations were well met. Collaboration with colleagues and facilitators helped teachers achieve their goals in terms of teaching within state curriculum standards. These findings have important implications for designing professional development to help teachers align instruction with curriculum standards.     

Assessing the Life Science Knowledge of Students and Teachers Represented by the K–8 National Science Standards

We report on the development of an item test bank and associated instruments based on the National Research Council (NRC) K–8 life sciences content standards. Utilizing hundreds of studies in the science education research literature on student misconceptions, we constructed 476 unique multiple-choice items that measure the degree to which test takers hold either a misconception or an accepted scientific view. Tested nationally with 30,594 students, following their study of life science, and their 353 teachers, these items reveal a range of interesting results, particularly student difficulties in mastering the NRC standards. Teachers also answered test items and demonstrated a high level of subject matter knowledge reflecting the standards of the grade level at which they teach, but exhibiting few misconceptions of their own. In addition, teachers predicted the difficulty of each item for their students and which of the wrong answers would be the most popular. Teachers were found to generally overestimate their own students’ performance and to have a high level of awareness of the particular misconceptions that their students hold on the K–4 standards, but a low level of awareness of misconceptions related to the 5–8 standards.     

The Impact of Teachers and Their Science Teaching on Students’ ‘Science Interest’: A four-year study

There is a crisis in school science in Australia and this may be related to insufficient students developing an interest in science. This extended study looked at changes in 14 students’ interest in science as they moved through junior secondary school into Year 10. Although the majority of these students still had an interest in science in Year 10, it had fluctuated for most students from year to year. The presence or absence of simple, but effective, teaching practices, identified by these students, seems to suggest one way to retain or improve situational and, it would appear, in several cases, personal interest.     

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.     

Teachers’ Understanding and Operationalisation of ‘Science Capital’

Across the globe, governments, industry and educationalists are in agreement that more needs to be done to increase and broaden participation in post-16 science. Schools, as well as teachers, are seen as key in this effort. Previous research has found that engagement with science, inclination to study science and understanding of the value of science strongly relates to a student's science capital. This paper reports on findings from the pilot year of a one-year professional development (PD) programme designed to work with secondary-school teachers to build students’ science capital. The PD programme introduced teachers to the nature and importance of science capital and thereafter supported them to develop ways of implementing science capital-building pedagogy in their practice. The data comprise interviews with the participating teachers (n?=?10), observations of classroom practices and analyses of the teachers’ accounts of their practice. Our findings suggest that teachers found the concept of science capital to be compelling and to resonate with their own intuitive understandings and experiences. However, the ways in which the concept was operationalised in terms of the implementation of pedagogical practices varied. The difficulties inherent in the operationalisation are examined and recommendations for future work with teachers around the concept of science capital are developed.

Assessment of Understanding: Student Teachers’ Preparation,Implementation and Reflection of a Lesson Plan for Science

Research finds that student teachers often fail to make observable instructional goals, without which a secure bridge between instruction and assessment is precluded. This is one reason that recent reports state that teacher education needs to become better at helping student teachers to develop their thinking about and skills in assessing pupils’ learning. Currently in Europe, the Lesson Study method and the Content Representation tool, which both have a specific focus on assessment, have started to address this problem. This article describes and discusses an intervention in which Lesson Study was used in combination with Content Representation in student teachers’ field practice. Empirical materials from one group of student teachers were analyzed to illustrate how the student teachers worked with assessment during the planning of a lesson, how they implemented it in a research lesson, and how they used the gathered observations to make claims about assessment aims. The findings suggest that the student teachers placed greater emphasis on assessment through the intervention. However, it is also found that more attention should have been dedicated to the planning phase and that the group did not manage to keep a research focus throughout the Lesson Study process. This suggests that it properly would be beneficial with several planning sessions prior to the research lesson, as well as having an expert teacher leading the Lesson Study.     

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.     

Do Science Teachers Distinguish Between Their own Learning and the Learning of Their Students?

Learning beliefs influence learning and teaching. For this reason, teachers and teacher educators need to be aware of them. To support students’ knowledge construction, teachers must develop appropriate learning and teaching beliefs. Teachers appear to have difficulties when analysing students’ learning. This seems to be due to the inability to differentiate the beliefs about their students’ learning from those about their own learning. Both types of beliefs seem to be intertwined. This study focuses on whether pre-service teachers’ beliefs about their own learning are identical to those about their students’ learning. Using a sample of pre-service teachers, we measured general beliefs about “constructivist” and “transmissive” learning and science-specific beliefs about “connectivity” and “taking pre-concepts into account”. We also analysed the development of these four beliefs during teacher professionalisation by comparing beginning and advanced pre-service teachers. Our results show that although pre-service teachers make the distinction between their own learning and the learning of their students for the general tenets of constructivist and transmissive learning, there is no significant difference for science-specific beliefs. The beliefs pre-service teachers hold about their students’ science learning remain closely tied to their own.     

Exploring Prospective Teachers’ Worldviews and Conceptions of Nature of Science

This study explores the relationship, if any, between an individual’s culturally based worldviews and conceptions of nature of science. In addition, the implications of this relationship (or lack of relationship) for science teaching and learning are discussed. Participants were 54 Taiwanese prospective science teachers. Their conceptions of nature of science and their worldviews specific to humans’ relationship with the natural world were assessed using two open‐ended questionnaires in conjunction with follow‐up interviews. Their understandings of nature of science were classified into informed and naïve categories based upon contemporary views of these constructs and those stressed in international reform documents. An anthropocentric–naturecentric continuum emerged and is used to explain the participants’ views about humans’ relationship with Nature. Participants who recognized the limitations of scientific knowledge, and accept the idea that science involves subjective and cultural components, were more likely to emphasize harmony with Nature. In contrast, participants who possessed narrow views about the scientific enterprise and described science as close to technology and as of materialistic benefit tended to provide an anthropocentric perspective regarding the human–Nature relationships. The findings illustrate the interplay between participants’ sociocultural beliefs and conceptions of nature of science. Concisely, people with different worldviews may have concurrently different views about nature of science. The study suggests the need for incorporating sociocultural perspectives and nature of science in the science curriculum.

Chinese Secondary School Science Teachers’ Understanding of the Nature of Science—Emerging from Their Views of Nature

The findings reported in this paper report on an investigation of Chinese people’s understanding of the nature of science in relation to their conceptualisations of Nature. As an exploratory and interpretive study, it uses semi-structured interviews with 25 Chinese secondary school science teachers. The paper first presents these teachers’ conceptualisations of Nature, which were mainly scientifically informed and showed a mixed influence of both traditional and modern Chinese ideas about Nature. Teachers’ functional understandings of the nature of science were then inferred from their conceptualisations of Nature and presented from three perspectives: that of science; the strategies and approaches to doing science; and, the status of scientific knowledge.     

Effects of the Science Writing Heuristic Approach on the Quality of Prospective Science Teachers’ Argumentative Writing and Their Understanding of Scientific Argumentation

This study investigates the effect of the science writing heuristic (SWH) approach on the quality of prospective science teachers’ (PSTs) argumentative writing and their understanding of the components of argumentation in the SWH approach and their own learning. Ten SWH approach activities were implemented during the semester. The study was carried out with 31 PSTs. A case study design was used. Data included the SWH approach’s grading rubric and semistructured interviews. While the ANOVA and Bonferroni tests were used to analyze the SWH approach’s grading rubric, content analysis was used to analyze the semistructured interviews conducted with 12 PSTs. The ANOVA results showed a statistical difference among the writing performance of the PSTs (F = 14.493, p < 0.01). The findings gathered from the interviews revealed that the quality of the argumentative writing and research skills of the PSTs increased over time. The PSTs made explicit associations among their beginning questions, data and observations, and claims and evidence, and they made distinctions between their data, observations, and evidence. Multiple representations played an important role in providing evidence to support claims. Moreover, the process of negotiation helped PSTs learn more effectively, and they believed that the argument-based inquiry lab was beneficial to their learning and their future vocational careers as teachers.
