Storylines in the physics teaching content of an upper secondary school classroom

ABSTRACT

Background: Physics is often seen as a discipline with difficult content, and one that is difficult to identify with. Socialisation processes at the upper secondary school level are of particular interest as these may be linked to the subsequent low and uneven participation in university physics. Focusing on how norms are construed in physics classrooms in upper secondary school is therefore relevant.

Purpose: The purpose of this paper is to identify discursive patterns in teacher–student interactions in physics classrooms.

Design and methods: Three different physics lessons with one class of students taught by three different teachers in upper secondary school were video-recorded. Positioning theory was used to analyse classroom interaction with a specific focus on how physics was positioned.

Results: We identified seven different storylines. Four of them (‘reaching a solution to textbook problems’, ‘discussing physics concepts in order to gain better understanding’, ‘doing empirical enquiry’ and ‘preparing for the upcoming exam’) represent what teaching physics in an upper secondary school classroom can be. The last three storylines (‘mastering physics’, ‘appreciating physics’ and ‘having a feeling for physics’) all concern how students are supposed to relate to physics and, thus, become ‘insiders’ in the discipline.

Conclusions: The identification and analysis of storylines raises awareness of the choices teachers make in physics education and their potential consequences for students. For example, in the storyline of mastering physics a good physics student is associated with ‘smartness’, which might make the classroom a less secure place in general. Variation and diversity in the storylines construed in teaching can potentially contribute to a more inclusive physics education.     

Comparing Classroom Enactments of an Inquiry Curriculum: Lessons Learned From Two Teachers

Abstract

Examining how teachers structure the activities in a unit and how they facilitate classroom discussion is important to understand how innovative technology-rich curricula work in the context of classroom instruction. This study compared 2 enactments of an inquiry curriculum, then examined students' learning outcomes in classes taught by 2 teachers. The quantitative data show that there were significant differences in the learning outcomes of students in classes of the 2 teachers. This study then examined classroom enactments by the 2 teachers to understand the differences in the learning outcomes. This research specifically focused on how teacher-led discussions (a) helped connect the activities within a curriculum unit and (b) enabled deeper conceptual understanding by helping students make connections between science concepts and principles. This study examined the role that teacher facilitation played in helping students focus on the relations between the various activities in the unit and the concepts that they were learning. The results point to important differences in the 2 enactments, helping to understand better what strategies might enable a deeper conceptual understanding of the science content.     

Teachers’ differing perceptions of classroom disturbances

Background: Efficient classroom management and adequate discipline are major issues for teachers in schools worldwide, with the guiding of students’ behaviour as one of the primary challenges. Teachers’ knowledge, skills, attitudes and behaviour play central roles in the appropriate handling of classroom disturbances.

Purpose: The purpose of this study is to explore how practising teachers perceive classroom disturbances and to compare their views to those presented in the literature. By clarifying typical perceptions, this research is intended to give individual teachers tools to develop their insights by comparing their perceptions with those of other teachers.

Sample: The empirical material was collected by interviewing 14 home economics teachers in Finland. Home economics is a school subject that involves individual and group work as well as theoretical and practical work. In Finland, home economics is a compulsory subject for students aged 13–15 years, which are challenging ages in regard to classroom management.

Design and methods: The empirical research was completed via deep, qualitative theme interviews for data gathering and phenomenography for analysis.

Results: The analysis identified five dimensions in which interviewees expressed varying views of classroom disturbances: who or what disturbs, whose work is disturbed, why students disturb, who is responsible and how to prevent classroom disturbances. Based on the various perceptions within each dimension, the main perceptions for understanding classroom disturbances can be condensed into four categories: unavoidable nuisance, deficient resources, the matter of atmosphere and educational task.

Conclusions: Teachers who wish to develop their classroom management skills may use these findings as tools to compare their perceptions with those of other teachers. This knowledge may also be useful for developing teacher education.     

Connecting Classroom Science with Everyday Life: Teachers’ Attempts and Students’ Insights

This multiple case study examines how teachers request students’ use of their content knowledge and conceptual understandings from out-of-school experiences while reasoning about science concepts and the ways in which students perceive and respond to these requests. Three middle school teachers and a total of 57 middle school students participated in this study. The data collection involved classroom observations and multiple interviews with each of the teachers individually and with small groups of students. The findings indicate that the students appreciate the usefulness of making relevant connections between their in-school and out-of-school learning, but seldom do so during science lessons. We also found that teachers’ attempts to facilitate these types of connections during classroom discourse events involved the use of analogies, examples, or questions. Finally, the findings also indicate that students often recognize teachers’ requests but seldom relate to these requests in the way the teacher intends.     

Promoting cognitive and social aspects of inquiry through classroom discourse

We investigated how Chinese physics teachers structured classroom discourse to support the cognitive and social aspects of inquiry-based science learning. Regarding the cognitive aspect, we examined to what extent the cognitive processes underlying the scientific skills and the disciplinary reasoning behind the content knowledge were taught. Regarding the social aspect, we examined how classroom discourse supported student learning in terms of students' opportunities to talk and interaction patterns. Our participants were 17 physics teachers who were actively engaged in teacher education programs in universities and professional development programs in local school districts. We analyzed one lesson video from each participating teacher. The results suggest both promises and challenges. Regarding the cognitive aspect of inquiry, the teachers in general recognized the importance of teaching the cognitive processes and disciplinary reasoning. However, they were less likely to address common intuitive ideas about science concepts and principles. Regarding the social aspect of inquiry, the teachers frequently interacted with students in class. However, it appeared that facilitating conversations among students and prompting students to talk about their own ideas are challenging. We discuss the implications of these findings for teacher education programs and professional development programs in China.     

Second year teacher candidates reflect on information technology in ontario secondary schools: how it is being used and the challenges it presents

Abstract

This article documents observations of pre-service teachers about how both students and teachers are using information technology in 374 secondary classrooms in Ontario, Canada. Also reported are some of the challenges that have resulted since the advent of this technology in these schools. The findings have direct implications for teacher education. Not only must teacher candidates learn how to use and apply this new technology, but they must be made aware of other issues (such as classroom management issues) stemming from the integration of information technology in the classroom. Teacher education programs must remain current: one way of doing this is to investigate ongoing classroom practices and issues. This article helps to identify both     

Attributions and emotional competence: why some teachers experience close relationships with disruptive students (and others don’t)

ABSTRACT

Disruptive student behaviour is a major concern for teachers, causing classroom conflict and emotional fatigue. Whilst student-teacher closeness is known to reduce student aggression and improve behaviour, it is not yet known why some teachers experience close relationships with disruptive students and others do not. This qualitative study therefore examined relational closeness between elementary teachers and disruptive students in Sydney, Australia. Using a teacher speech sample task, we identified eight disruptive students with ‘complicated’ student-teacher relationships: high in both closeness and conflict. Eleven classroom teachers and seven support teachers each spoke about their relationships with the eight students. Speech samples were analysed using an inductive content analysis to determine characteristics that may facilitate relational closeness in spite of student-teacher conflict. Findings revealed two characteristics of teachers’ speech that guided relational closeness: attributions for disruptive behaviour and emotional competence. Not all teachers, however, described a close relationship. These findings provide new directions for interventions that aim to improve student-teacher relationship quality.     

Classroom disruptions,the teacher–student relationship and classroom management from the perspective of teachers,students and external observers: a multimethod approach

This study used questionnaires and systematic behavioural observations to examine how teachers, students and external observers perceived classroom disruptions, the teacher–student relationship and classroom management in grade 5 and 6 classrooms in Switzerland. The questionnaire showed that the students of a class agreed to a certain extent in their ratings of classroom disruptions, the teacher–student relationship and classroom management. Comparison of teachers’ and students’ ratings showed that agreement on these constructs varied. We found weak to moderate agreement on classroom disruptions, a weak correspondence for the teacher–student relationship, and no association on classroom management. The results of the behavioural observation showed a moderate agreement between external observers’ and students’ ratings, but no association between external observers’ and class teachers’ ratings and only a weak correspondence with the subject teacher ratings. Thus external observers’ low-inference observations corresponded far better with students’ than teachers’ ratings. To sum up, students, teachers and observers perceive classroom processes differently.

     

Concept substitution: An instructional strategy for promoting conceptual change

Numerous studies have shown that students often hold conceptions that conflict with accepted scientific ideas, both prior to and after instruction. The failure of instruction to affect students' conceptions can be interpreted as a failure to facilitate conceptual change. In this paper, an instructional strategy will be described that facilitates conceptual change in the special case where conceptual difficulties appear to arise because students confuse related physics concepts. The strategy involves two parts. Firstly, students observe an experiment or demonstration that conflicts with what they expect to see. Secondly, the instructor identifies students' intuitions that are correct but that they have associated with an incorrect physics term, and substitutes the correct physics term. Students can thus develop more scientifically acceptable understandings of physics concepts without having to give up their intuitive ideas. The use of this strategy will be illustrated in two domains of physics. Specializations: physics education, conceptual development, instructional design, improvement of tertiary science education.     

Preservice elementary teachers' perceptions of their science laboratory instructors in a phenomena-based laboratory and how it impacts their conceptual development

Phenomena-based approaches have become popular for elementary school teachers to engage children's innate curiosity in the natural world. However, integrating such phenomena-based approaches in existing science courses within teacher education programs present potential challenges for both preservice elementary teachers (PSETs) and for laboratory instructors, both of whom may have had limited opportunities to learn or teach science within the student and instructor roles inherent within these approaches. This study uses a convergent parallel mixed-methods approach to investigate PSETs' perceptions of their laboratory instructor's role within a Physical Science phenomena-based laboratory curriculum and how it impacts their conceptual development (2 instructors/121 students). We also examine how the two laboratory instructors' discursive moves within the laboratory align with their's and PSETs' perceptions of the instructor role. Qualitative data includes triangulation between a student questionnaire, an instructor questionnaire, and video classroom observations, while quantitative data includes a nine-item open response pre-/post-semester conceptual test. Guided by Mortimer's and Scott's analytic framework, our findings show that students primarily perceive their instructors as a guide/facilitator or an authoritarian/evaluator. Using Linn's knowledge integration framework, analysis of pre-/post-tests indicates that student outcomes align with students' perceptions of their instructors, with students who perceive their instructor as a guide/facilitator having significantly better pre-/post-outcomes. Additional analysis of scientific discourse from the classroom observations illustrates how one instructor primarily supports PSETs' perspectives on authentic science learning through dialogic–interactive talk moves whereas the other instructor epistemologically stifles personally relevant investigations with authoritative–interactive or authoritative–noninteractive discourse moves. Overall, this study concludes by discussing challenges facing laboratory instructors that need careful consideration for phenomena-based approaches.     

How can a Website for Physics Teachers Serve as a Tool for Professional Development?

Misconceptions among students studying physics have been widely reported in the research literature. Many teachers are not acquainted with this literature. Moreover, many of them claim that only weak students have misconceptions. This paper reports on an online activity focusing on misconceptions of students regarding Newton’s 3rd Law, that is being carried out through the website of the National Center of Physics Teachers. The aims of the activity are: (1) To convince the teachers that sometimes difficulties in understanding concepts do not stem from the inability of certain students to understand the concept, but rather because of misconceptions in physics. (2) To present the teachers with the findings of studies on physics instruction that deal with the concepts under discussion. (3) To convince the teachers to try out new, innovative teaching strategies.     

Quantum Literacy

Quantum physics provides an alternative to classical explanations of matter and energy, and may have metaphoric utility in substantiating cognitive explanations of human information processing. Three concepts central to an understanding of the sub-atomic world of quantum physics are: (1) the role of the observer in the interpretation of events; (2) the uncertainty of physical states; and (3) the interconnectedness of the physical world. These concepts have parallels in the psychological world. They support a theory of literacy and learning that, when applied to the teaching of English explains: (1) the role of readers, authors, teachers and contexts in the construction of meaning; (2) the uncertainty and impermanence of meaning; and (3) the interconnectedness of meaning. These concepts challenge mechanistic explanations of behavioural psychology and associated pedagogy used by some teachers of English. Quantum-consistent English teaching engages teachers and students in practices that result in different kinds and levels of literate competence and achievement, and that provide different constructions of what counts as literacy.     

Insights into teacher learning about pedagogy from an international group of teachers of students with severe intellectual disabilities

This article examines teacher professional learning about pedagogy for teachers of students with severe intellectual disabilities within broader teacher education and pedagogical frameworks for this group of learners. The article presents and discusses findings from a USA–England research project, involving classroom observations and interviews with nine teachers of students with severe intellectual disabilities from four specialist public school settings, intended to explore teachers’ pedagogical decision-making and learning. The theoretical lens of situated learning and the conceptual lens of evidence-based practice are used to contextualise and examine the teachers’ views about the what, how and when they learn about pedagogical approaches and strategies. Teachers emphasised the situated and interactional nature of their learning, particularly highlighting the personal responses of students and their relationship with these students. They use this knowledge and understanding to adapt evidence-based strategies and programmes and inform their pedagogical decisions. This affords the concepts of ‘situated generalization’ and ‘practice based evidence’ an influential role in how teachers engage in the process of pedagogical decision-making. An implication for teacher educators is the need to support teachers in making connections of new pedagogical understandings and skills with the individual learning profiles and responses of their students with severe intellectual disabilities.     

Using information and communication technology (ICT) to the maximum: learning and teaching biology with limited digital technologies

Background: The ubiquity, availability and exponential growth of digital information and communication technology (ICT) creates unique opportunities for learning and teaching in the senior secondary school biology curriculum. Digital technologies make it possible for emerging disciplinary knowledge and understanding of biological processes previously too small, large, slow or fast to be taught. Indeed, much of bioscience can now be effectively taught via digital technology, since its representational and symbolic forms are in digital formats.

Purpose: This paper is part of a larger Australian study dealing with the technologies and modalities of learning biology in secondary schools.

Sample: The classroom practices of three experienced biology teachers, working in a range of NSW secondary schools, are compared and contrasted to illustrate how the challenges of limited technologies are confronted to seamlessly integrate what is available into a number of molecular genetics lessons to enhance student learning.

Design and method: The data are qualitative and the analysis is based on video classroom observations and semi-structured teacher interviews.

Results: Findings indicate that if professional development opportunities are provided where the pedagogy of learning and teaching of both the relevant biology and its digital representations are available, then teachers see the immediate pedagogic benefit to student learning. In particular, teachers use ICT for challenging genetic concepts despite limited computer hardware and software availability.

Conclusion: Experienced teachers incorporate ICT, however limited, in order to improve the quality of student learning.     

“I believe I will go out of this class actually knowing something”: Cooperative learning activities in physical chemistry

The purposes of this study were to describe the structure of events during cooperative learning activities—Friday discussion sessions—in a graduate-level thermodynamics course and to understand what these activities meant to the students. First, we describe the structure of Friday discussion sessions in our classroom, which were used to focus student attention on conceptual issues rather than algorithmic problem solving. Second, we delineate findings which emerge from the perspective of the students. We found that cooperative learning activities move students away from rote learning strategies and toward more meaningful strategies which allowed them to integrate concepts over the entire semester. In addition, we discovered that the sharing of insights and ideas between students leads to the development of interpersonal skills and communication skills which the students perceive as an important component of the Friday discussion sessions. Implications for further classroom use, low-status versus high-status students, and assessment are discussed. J Res Sci Teach 34: 819–835, 1997.     

Factors Influencing Preservice Teachers’ Self-Efficacy in Addressing Cultural and Linguistic Needs of Diverse Learners

Abstract

How preservice teachers perceive their readiness to work with diverse learners can indicate their future success in the classroom. Using self-efficacy theory as a conceptual base, this study examined what factors contribute to preservice teachers’ self-efficacy level in addressing English Learners’ (ELs) cultural and linguistic needs, while adopting a multi-method design. Data sources included a self-efficacy survey of a group of preservice teachers, written rationales for their self-efficacy ratings, and suggestions for improving their self-efficacy. Data analyses revealed that the preservice teachers lacked self-efficacy in communicating with ELs while showing high self-efficacy in employing different learning modalities. In addition, direct exposure through field and/or life experiences and curriculum emphasis were identified as key factors. Findings further illuminate the preservice teachers’ incongruent understandings of mainstream school culture versus ELs’ cultures, the role of culture in academic versus social and emotional domains, and lack of interconnectedness between academic excellence and cultural competency.     

Engaging Students in Guided Science Inquiry Discussions: Elementary Teachers’ Oral Strategies

This study explores how elementary teachers perceive and use engaging oral strategies (i.e., manners of speaking that encourage students to participate and become engaged in science discussions). It is reported that the strategies employed as well as their frequency varied substantially depending upon on the teachers’ grade level and perceptions. While a kindergarten teacher viewed such strategies negatively and employed only a few figurative directives, fourth-grade teachers viewed them positively, frequently resorting to a variety of speech figures, parallel repetition and engaging questions. It is argued that teachers’ engaging oral strategies are multifunctional, serving important social and cognitive functions.     

Developing an instrument for assessing students’ concepts of the nature of technology

Background: In Bangladesh, a common science curriculum caters for all students at the junior secondary level. Since this curriculum is for all students, its aims are both to build a strong foundation in science while still providing students with the opportunities to use science in everyday life – an aim consistent with the notion of scientific literacy.

Purpose: This paper reports Bangladeshi science teachers’ perspectives and practices in regard to the promotion of scientific literacy.

Sample: Six science teachers representing a range of geographical locations, school types with different class sizes, lengths of teaching experience and educational qualifications.

Design and method: This study employed a case study approach. The six teachers and their associated science classes (including students) were considered as six cases. Data were gathered through observing the teachers’ science lessons, interviewing them twice – once before and once after the lesson observation, and interviewing their students in focus groups.

Results: This study reveals that participating teachers held a range of perspectives on scientific literacy, including some naïve perspectives. In addition, their perspectives were often not seen to be realised in the classroom as for teachers the emphasis of learning science was more traditional in nature. Many of their teaching practices promoted a culture of academic science that resulted in students’ difficulty in finding connections between the science they study in school and their everyday lives. This research also identified the tension which teachers encountered between their religious values and science values while they were teaching science in a culture with a religious tradition.

Conclusions: The professional development practice for science teachers in Bangladesh with its emphasis on developing science content knowledge may limit the scope for promoting the concepts of scientific literacy. Opportunities for developing pedagogic knowledge is also limited and consequently impacts on teachers’ ability to develop the concepts of scientific literacy and learn how to teach for its promotion.     

A study of practical‐moral knowledge in science teaching: Case studies in physical science classrooms

This study further extends a conceptual framework that explores science teaching as a “practice” not reducible to the application of formal knowledge, but as informed by teachers' practical‐moral knowledge. A hermeneutic model was developed to examine practical‐moral knowledge indirectly by investigating teachers' commitments, interpretations, actions, and dialectic interactions between them. The study also aimed to analyze teachers' actions in terms of their interpretations and commitments as they realize “internal goods” of their practice. Ethnographic case studies of three science teachers were conducted through classroom observation, in‐depth interviews and dialogues, and artifact analysis. A commitment of preparing students for national exams was common to the three teachers but was manifested differently in classroom practices. This commitment originated from interpretations about the duty of “good” teachers not letting students and schools down. Other emergent commitments were commitments: to conceptual understandings, to “challenge” learners, and to social modeling. We present each with associated interpretations and actions. The concepts of practical wisdom (phronesis) and gap closing are used to characterize teachers' practical knowledge and its development respectively. Implications for teacher education are discussed. © 2010 Wiley Periodicals, Inc. J Res Sci Teach 47: 929–951, 2010
