Explaining Student Achievement: the Influence of Teachers’ Pedagogical Content Knowledge in Statistics

Statistics is an increasingly important component of the mathematics curriculum. StatSmart was a project intended to influence middle-years students’ learning outcomes in statistics through the provision of appropriate professional learning opportunities and technology to teachers. Participating students in grade 5/6 to grade 9 undertook three tests, a pre-test, a post-test and a longitudinal retention test over a period of 2 years. Their teachers completed a survey that included items measuring pedagogical content knowledge (PCK) for teaching statistics. Despite the development of valid instruments to measure both student and teacher content knowledge and teachers’ PCK, linking teachers’ knowledge directly to students’ learning outcomes has proved elusive. Multilevel modelling of results from 789 students for whom there were 3 completed tests and measures from their teachers indicated that students’ outcomes were influenced positively by their initial teacher’s PCK. Extended participation of teachers in the project also appeared to reduce negative effects of changing teachers.     

Teachers’ Concerns About Biotechnology Education

The impacts of biotechnology are found in nearly all sectors of society from health care and food products to environmental issues and energy sources. Despite the significance of biotechnology within the sciences, it has not become a prominent trend in science education. In this study, we seek to more fully identify biology teachers’ concerns about biotechnology instruction and their reported practices. Consistent with the Stages of Concern framework as modified by Hord et al., we investigated teachers’ awareness, informational, personal, management, consequences, collaboration, and refocusing concerns about biotechnology teaching by employing a qualitative design that allowed for the emergence of teachers’ ideas. Twenty high school life science teachers attending a biotechnology institute were interviewed using an interview protocol specifically designed to target various Stages of Concern. Although the Stages of Concern framework guided the development of interview questions in order to target a wide range of concerns, data analysis employed a grounded theory approach wherein patterns emerged from teachers’ own words and were constantly compared with each other to generate larger themes. Our results have potential to provide guidance for professional development providers and curriculum developers committed to supporting initial implementation of biotechnology education. Recommendations include supporting teacher development of biotechnology content knowledge; promoting strategies for obtaining, storing and managing biotechnology equipment and materials; providing opportunities for peer teaching as a means of building teacher confidence; and highlighting career opportunities in biotechnology and the intersections of biotechnology and everyday life.     

Finnish Cooperating Physics Teachers’ Conceptions of Physics Teachers’ Teacher Knowledge

This article examines Finnish cooperating physics teachers’ conceptions of teacher knowledge in physics. Six experienced teachers were interviewed. The data was analyzed to form categories concerning the basis of teacher knowledge, and the tradition of German Didaktik and Shulman’s theory of teacher knowledge were used in order to understand the results. The results show that the teachers strongly emphasize knowledge related to day-to-day teaching practice. In German Didaktik, this means knowledge of the best instructional methods, while in Shulman’s categorization it belongs to the category of representations, strategies, and methods. It was also found that the teachers appear to lack some of the essential key ideas of modern physics teacher education, such as a holistic view of instructional approaches.     

A Study on Student Teachers’ Misconceptions and Scientifically Acceptable Conceptions About Mass and Gravity

The aims of this study were considered under three headings. The first was to elicit misconception that science and physics student teachers (pre-service teachers) had about the terms, ‘‘inertial mass’’, ‘‘gravitational mass’’, ‘‘gravity’’, ‘‘gravitational force’’ and “weight”. The second was to understand how prior learning affected their misconceptions, and whether teachers’ misconceptions affected their students’ learning. The third was to determine the differences between science and physics student teachers’ understanding levels related to mass and gravity, and between their logical thinking ability levels and their attitudes toward physics lessons. A total of 267 science and physics student teachers participated in the study. Data collection instruments included the physics concept test, the logical thinking ability test and physics attitude scale. All instruments were administered to the participants at the end of the 3rd semester of their university years. The physics test consisting of paper and pencil test involving 16 questions was designed, but only four questions were related to mass and gravity; the second test consisted of 10 questions with two stages. The third test however, consisted of 15 likert type items. As a result of the analysis undertaken, it was found that student teachers had serious misconceptions about inertia, gravity, gravitational acceleration, gravitational force and weight concepts. The results also revealed that student teachers generally had positive attitudes toward physics lessons, and their logical thinking level was fairly good.

How do Student Teachers Elicit their Mentor Teachers' Practical Knowledge?

The present study focuses on how student-teachers attempt to elicit the practical knowledge of the mentor teachers who supervise their practical training. Having access to the practical knowledge of their mentors means, among other things, that student-teachers have access to the cognitions underlying teaching that can help them to understand their mentors' teaching style, advice, and feedback. The analysis of 29 interviews with student-teachers revealed three self-initiated activities for this access: (1) observing a mentor's lesson; (2) asking specific questions about lessons observed; and (3) discussing the student's lesson or teaching and education in general. Not all the activities mentioned by the student-teachers elicited what is called 'practical knowledge' in the literature. As practical knowledge is an important element of the learning-to-teach process, it was concluded that the stimulation of activities aimed at exploring this knowledge could make a valuable contribution to teacher education. The instruments used in the research on teacher knowledge and beliefs could be helpful for attaining this objective. Implications of this research for teacher education and suggestions for further research are presented.     

The Assessment of Student Teachers’ Academic and Professional Knowledge in School‐Based Teacher Education

The aim of this study was to scrutinize the assessment of teacher knowledge in a school‐based course at one Swedish pre‐service teacher education program. In a general education school‐based course, teacher educators visited the student teachers at their school placements and met them and their school mentors in student‐teaching conferences to assess their teacher knowledge. The findings primarily show that the assessment procedures are influenced by teacher educators’ organization of the school visits and conferences. Secondly, the organization of the school visits and conferences influences who the potential and actual assessors at the conferences can be and are. Thirdly, the assessed student teacher knowledge at the conferences is described as procedural knowledge in a knowledge‐in‐practice perspective, almost exclusively in the area of relational, emotional, and caring learning objectives and aspects of teaching activities. Fourthly, the findings show that propositional knowledge in a knowledge‐for‐practice perspective is hardly mentioned or assessed.     

Chemistry Teachers’ Knowledge and Application of Models

Teachers’ knowledge and application of model play an important role in students’ development of modeling ability and scientific literacy. In this study, we investigated Chinese chemistry teachers’ knowledge and application of models. Data were collected through test questionnaire and analyzed quantitatively and qualitatively. The result indicated as follows: (1) Chemistry teachers’ knowledge of some known chemistry models was limited; (2) Chemistry teachers preferred those models that were vivid when they chose models; (3) Teachers’ modeling process was incomplete; (4) Teachers adopted a general pattern when applying models in chemistry teaching. The findings have implications for teacher education.     

Capturing and Enhancing Science Teachers’ Professional Knowledge

This paper reports research from a three-year Australian science teacher professional learning project, the Science Teaching and Learning (STaL) Project, in which groups of science teacher participants (across years K – 12) worked with academics over a one-year period as teacher researchers. Through reflecting on their experiences within the STaL Project and collecting data from their classrooms related to specific science teaching concerns, teacher participants constructed cases around particular aspects of their professional learning. The cases that these participants developed elicited rich insights into their teaching and their students’ learning of science. This paper discusses how the cases were developed by the teacher researcher participants and uses exemplars as a way of illustrating the nature of the professional knowledge developed.     

Preservice Elementary Teachers’ Beliefs About Science Teaching

In this study, a Beliefs About Teaching (BAT) scale was created to examine preservice elementary science teachers’ self-reported comfort level with both traditional and reform-based teaching methods, assessment techniques, classroom management techniques, and science content. Participants included 166 preservice teachers from three different US universities. Analyses revealed significant correlations among participants’ confidence level with assessment techniques, classroom management, teaching methods, and science content and number of science methods and science content courses taken. A significant difference was observed among the students enrolled at each university. Overall, study participants felt more comfortable teaching biology concepts than teaching chemistry concepts, physics concepts, or both.     

Developing Teachers’ Knowledge,Beliefs, and Expertise: Findings From the Alberta Student Assessment Study

This article reports on a subset of findings that emerged from the Alberta Student Assessment Study in relation to the preservice and in-service development of teacher knowledge of, expertise in, and beliefs underpinning their assessment practices. Findings indicate that, although there has been a lot of attention given to improving assessment, confusion remains for teachers about terminology, principles, and pragmatics that undermine teacher confidence about assessment and making sound judgments about students’ work.     

Preservice Elementary Teachers’ Ideas About Scientific Practices

With the goal of producing scientifically literate citizens who are able to make informed decisions and reason critically when science intersects with their everyday lives, the National Research Council (NRC) has produced two recent documents that call for a new approach to K-12 science education that is based on scientific practices, crosscutting concepts, and disciplinary core ideas. These documents will potentially influence future state standards and K-12 curricula. Teachers will need support in order to teach science using a practices based approach, particularly if they do not have strong science backgrounds, which is often the case with elementary teachers. This study investigates one cohort (n = 19) of preservice elementary teachers’ ideas about scientific practices, as developed in a one-semester elementary science teaching methods course. The course focused on eight particular scientific practices, as defined by the National Research Council’s A Framework for K-12 Science Education: Practices, Crosscutting Concepts, and Core Ideas (2012). Participants’ written reflections, lesson plans and annotated teaching videos were analyzed in fine detail to better understand their ideas about what it means to engage in each of the practices. The findings suggest that preservice elementary teachers hold promising ideas about scientific practices (such as an emphasis on argumentation and communication between scientists, critical thinking, and answering and asking questions as the goal of science) as well as problematic ideas (including confusion over the purpose of modeling and the process of analysis, and conflating argumentation and explanation building). These results highlight the strengths and limitations of using the Framework (NRC 2012) as an instructional text and the difficulties of differentiating between preservice teachers’ content knowledge about doing the practices and their pedagogical knowledge about teaching the practices.     

A Qualitative Case Study of Prospective Chemistry Teachers’ Knowledge About Instructional Strategies: Introducing Particulate Theory

The purpose of this study was to investigate prospective chemistry teachers’ knowledge about instructional strategies, one component of pedagogical content knowledge about introducing particulate theory, as well as sources of this knowledge. Twenty-two prospective chemistry teachers participated in the study. Data were collected by the means of a vignette, semistructured interviews, and lesson plans. Analysis showed that concrete objects, computer animations, and expository teaching were the preferred teaching techniques by prospective teachers. Several issues, such as general pedagogical knowledge, subject matter knowledge, and knowledge about students’ difficulties, were found to be the main factors for choosing a teaching strategy to make an introduction to particles.     

Elementary Teachers’ Use of Graphical Representations in Science Teaching

The purpose of this study was to obtain data on United States K-5 elementary school teachers’ self-reported instructional practices with graphical representations. Via an electronic survey, 388 elementary teachers, from throughout the US, reported about their teaching of the interpretation and the production of graphics within science. The main findings indicate that: (1) pointing to or referring to graphical representations in books (92% of respondents) was the most frequently used instructional practice across the disciplines and grade levels; (2) five of nine graphical representations (over 90%) were more frequently used in science instruction than in other content areas, and (3) students’ graphical productions involving drawings, labeling, and oral and written explanations were very infrequent. The findings indicate that while teachers may tacitly use graphics within science instruction, they may not be explicitly teaching about this visual form of communication.     

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.     

Investigating Teachers’ Skills in Interpreting Evidence of Student Learning

This study measured and explored the relationships among elementary mathematics teachers’ skill in (a) determining what an item measures, (b) analyzing student work, (c) providing targeted feedback, and (d) determining next instructional steps. Twenty-three elementary mathematics teachers were randomly assigned to one of three conditions: analyzing items and student responses without rubrics, analyzing items and student responses with rubrics, or analyzing items and student responses with rubrics after watching a professional development program on providing feedback to students. Findings show there is a moderate to strong relationship between teachers’ abilities to analyze student responses to infer what a student knows and can do and their abilities to take action based on that information through either providing the student feedback or making appropriate instructional adaptations. Findings show it was relatively more difficult for teachers to provide feedback that was likely to move students forward in their learning than it was for them to analyze a student's response or to determine next instructional steps. No teacher skill differences associated with the different treatment conditions were found.     

Stability and Change in Student Teachers’ Beliefs about Teaching

This study examined whether teachers prioritize the use of technology. More specifically, this paper focused on how Turkish teachers think about the importance of technology and technological tools for their daily routines. The research design employed both qualitative and quantitative methods. The data were collected through document analyses, interviews, and a survey. The results showed that the following factors lead teachers to prioritize the use of technology in the classroom: (a) globalization, (b) society’s needs, (c) technological literacy, (d) student learning, and (e) practicability.

What Do Teacher Mentors Tell Student Teachers About Pupil Learning in Infant Schools?

Abstract

Recent emphases on experiential classroom learning in the induction into expertise of student teachers may over‐estimate the learning support that class based practitioners offer students. Current understandings of teachers' thinking and planning suggest that expert practitioners may not be best placed to provide student teachers with frameworks for understanding what Shulman (1987) categorises as general pedagogical knowledge. Data from a sample of 11 UK infant school teacher mentors in the form of 5 hours of taped planning and evaluatory conversations with 20 students have been content analysed. Teacher‐talk related to explanations of how pupils learn forms the focus of the paper. Implications for mentor training and school‐university partnerships are drawn from the analysis of the data. Finally the need to confront the language difference that obtains between schools and universities in order to develop the theoretical base of teacher education is asserted.
