University physics students’ ideas of thermal radiation expressed in open laboratory activities using infrared cameras

Background: University physics students were engaged in open-ended thermodynamics laboratory activities with a focus on understanding a chosen phenomenon or the principle of laboratory apparatus, such as thermal radiation and a heat pump. Students had access to handheld infrared (IR) cameras for their investigations.

Purpose: The purpose of the research was to explore students’ interactions with reformed thermodynamics laboratory activities. It was guided by the research question: How do university physics students make use of IR cameras in open-ended investigation of thermal radiation as a phenomenon?

Sample: The study was conducted with a class of first-year university physics students in Sweden. The interaction with the activities of four of the students was selected for analysis. The four students are males.

Design and methods: We used a qualitative, interpretive approach to the study of students’ interaction. The primary means of data collection was video recording of students’ work with the laboratory activities and their subsequent presentations. The analysis focused on how IR cameras helped students notice phenomena relating to thermal radiation, with comparison to previous research on students’ conceptions of thermal radiation.

Results: When using the IR camera, students attended to the reflection of thermal radiation on shiny surfaces, such as polished metals, windows or a whiteboard and emissive properties of surfaces of different types. In this way, they went beyond using the technology as a temperature probe. Students were able to discuss merits and shortcomings of IR cameras in comparison with digital thermometers.

Conclusions: With the help of IR cameras, university physics students attend to thermal phenomena that would otherwise easily go unnoticed.     

‘Educare’ in Australia: analysing policy mobility and transformation

Abstract

Background: Early childhood education and care has been an area of significant policy attention, public investment and private market activity in Australia over the past three decades. Australian educationists and policy-makers have looked to international examples for evidence, policy design and institutional models. However, this area is under-researched in Australia, with regard to how these knowledge flows are theorised, and how policy is implemented on the ground.

Purpose: The paper’s purpose was to contribute new Australian-focussed conceptual and empirical insights on the trajectories, development and implementation of evidence-based policy in the field of early childhood education and care.

Sources of evidence: The paper is based on three main sources of evidence: ? the critical literature on policy transfer and policy mobility

? policy statements, reports and planning documents produced by national- and state-level governments

? data from fieldwork analysis of new capital works and programmes in the early childhood field.

Main argument: International research and evidence on the benefits of investment in early learning has had a significant impact on the framing of Australian policy. So too has a move in several countries to align early childhood institutions with schools. However, a dominant paradigm of policy transfer, reliant on pluralist and rationalist frameworks of policy-making, fails to account for the dynamics of policy development and implementation across and within jurisdictions and geographical space. Conceptualising a new alignment in Australia between children’s centres and schools as ‘educare’, this article employs the theoretical lens of policy mobility to account for the circulation and transformation of educare policy in Australian settings. Through an empirical analysis of a new educare centre in the growth corridor of western Melbourne, the article demonstrates the extent to which neoliberal policy settings outside the educational sphere, around public finance, partnership, place and infrastructure provision, influence the implementation of ‘educare’ policy.

Conclusions: The educare discourse in Australia addresses a complex and multiscalar set of policy problems that associate child development with concerns around human capital formation, economic efficiency and productivity, place making and community building, and the role of the public sector in neoliberal democracies. International circuits of knowledge, policy design and institutional models in the educare field have been significant in shaping recent Australian policy, despite well-publicised views expressed in Australia on the disconnection between academic research and policy. The strength of policy mobility as a theoretical lens to assist our understanding of these influences lies in its critique of formalism in policy-making and in its attention to fluidity and transformation. The mobility lens encourages new empirical research that focuses on spatial and institutional dynamics, assisting our reading of on-the-ground developments in Australia’s fastest growing city.     

Secondary school students’ attitudes to practical work in biology,chemistry and physics in England

ABSTRACT

Background: In England, practical work is a major part of secondary school science and yet little research has examined students’ attitudes specifically to practical work.

Purpose: To examine students’ attitudes to practical work in biology chemistry and physics in secondary schools in England.

Sample: The study involved 607 students from Year 7 to Year 10 (aged 11–15) drawn from three state-maintained secondary schools in England. The schools were, broadly speaking, representative of schools in England in terms of academic measures such as GCSE outcomes, value-added performance and socio-economic area.

Design and methods: The research considered students’ attitudes in terms of an established analytical framework incorporating the affective, behavioural and cognitive (ABC) domains and used a mixed methods approach involving questionnaires, lesson observations, and focus group discussions.

Results: Whilst secondary students’ attitudes to practical work were, generally speaking, positive they were not constant and homogenous but change over time. The affective value of practical work was found to vary by subject although in all three sciences this value decreased, albeit at different rates, as students approached their General Certificate in Secondary Education examinations (GCSE) taken at age 16.

Conclusion: The affective value of practical work needs to be considered on a subject by subject basis, rather than, as is often the case currently in school, in terms of a generic attitude to science practical work. Furthermore, the affective value of practical work can be maximised by using more at the start of secondary education (Key Stage 3 – ages 11–14) with a gradual, subject-specific, reduction as students approach their summative public examinations (age 16) when their preference for non-practical, exam orientated, teaching increases.     

Exploring the pedagogical features of integrating essential competencies of scientific inquiry in classroom teaching

ABSTRACT

Background: As inquiry-based instruction is not universally implemented in science classrooms, it is crucial to introduce instructional strategies through the use of contextualized learning activities to allow students with different background knowledge and abilities to learn the essential competencies of scientific inquiry and promote their emotional perception and engagement.

Purpose: This study explores how essential scientific competencies of inquiry can be integrated into classroom teaching practices and investigates both typical and gifted secondary students’ emotional perception and engagement in learning activities.

Sample: A case teacher along with 226 typical and 18 gifted students from a suburban secondary school at Taiwan participated in this study.

Design and methods: After attending twelve 3-hour professional development workshops that focused on scientific inquiry teaching, the case teacher voluntarily developed and elaborated her own teaching activities through the discussions and feedback that she received from workshop participants and science educators. Quantitative and qualitative data were collected through activity worksheet, questionnaire, video camera, and tape recorders. Frequency distribution, Mann-Whitney U test, and discourse analysis were used for data analyses.

Results: Case teacher’s teaching activities provide contextual investigations that allow students to practice making hypotheses, planning investigations, and presenting and evaluating findings. Students’ learning outcomes reveal that typical students can engage in inquiry-based learning with positive emotional perception as well as gifted students regardless of their ability level. Both gifted and typical students’ positive emotional perception of and active engagement in learning provide fresh insight into feasible instructions for teachers who are interested in inquiry-based teaching but have little available time to implement such instructions into their classrooms.

Conclusions: The results of our work begin to address the critical issues of inquiry-based teaching by providing an exemplary teaching unit encompassing essential scientific competencies     

Essay review: Some "unpopular" truths

Drawing on diverse theoretical perspectives and research, this paper focuses on the significance of settings in qualitative research as well as on associated problems with representations of settings in traditional analyses and reports. The central premise developed is that a deeper analysis of settings requires an unraveling of relations among settings in which individuals or groups participate. In this discussion, setting is defined as a fluid and mutable but bounded environment in which particular situations, interactions, and behaviors accrue to it as normal by virtue of history, cultural values, and beliefs. To represent the complexity of identity and power relations in educational research, author suggests six lenses that offer a multilayered picture of participants' lived experiences across multiple settings. These lenses have the potential to broaden researchers' representations of participants beyond what is often available in traditional analyses and reports of qualitative educational research. These six lenses on settings are not meant to be inclusive but to suggest that finer grained examinations of the social and cultural symbols that permeate settings may yield fresh perspectives on lived experience.     

Epistemological commitments in the learning of science: Examples from dynamics

An observation schedule was developed to find out if girls have less interaction with teachers than boys in physics lessons. The schedule was intended to be used by a single observer with pencil and paper. It was also intended that the analysis of the data collected should be as straightforward as possible, without the need for video or audio playback, as all interpretation of the classroom interaction takes place during the live observation.

It was found that boys received more ‘public’ interactions concerning the cognitive content of their physics lessons than girls. This seemed to be related to the higher incidence of boys calling out answers, rather than the teachers initiating more interactions with the boys.     

The Alternative Lenses of Assessment

Abstract

The use of the Diagnostic and Statistical Manual of Mental Disorders (DSM IV) as a teaching tool for social workers to understand mental illness has been debated for many years. The general consensus is that social workers need to be “familiar” with this classification system. Social Work's person in environment perspective, however, requires additional tools of assessment. This article provides the Alternative Lenses of Assessment as one such tool: Developmental-Adaptive lens, Political- Economic lens, Sociocultural lens, Neurobiological lens, and Situational- Environmental lens. A pedagogical method for presenting these lenses through clinical vignettes is provided. Student response to the Lenses using student-authored clinical vignettes is also discussed.     

How teaching practices are connected to student intention to enrol in upper secondary school physics courses

Background: In developed countries, it is challenging for teachers to select pedagogical practices that encourage students to enrol in science and technology courses in upper secondary school.

Purpose: Aiming to understand the enrolment dynamics, this study analyses sample-based data from Finland’s National Assessment in Science to determine whether pedagogical approaches influence student intention to enrol in upper secondary school physics courses.

Sample: This study examined a clustered sample of 2949 Finnish students in the final year of comprehensive school (15–16 years old).

Methods: Through explorative factor analysis, we extracted several variables that were expected to influence student intention to enrol in physics courses. We applied partial correlation to determine the underlying interdependencies of the variables.

Results: The analysis revealed that the main predictor of enrolment in upper secondary school physics courses is whether students feel that physics is important. Although statistically significant, partial correlations between variables were rather small. However, the analysis of partial correlations revealed that pedagogical practices influence inquiry and attitudinal factors. Pedagogical practices that emphasise science experimentation and the social construction of knowledge had the strongest influence.

Conclusions: The research implies that to increase student enrolment in physics courses, the way students interpret the subject’s importance needs to be addressed, which can be done by the pedagogical practices of discussion, teacher demonstrations, and practical work.     

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.     

High school students’ scientific epistemological beliefs,self-efficacy in learning physics and attitudes toward physics: a structural equation model

Background: There are some theoretical evidences that explain the relationships between core beliefs (i.e., epistemological beliefs) and peripheral beliefs (self-efficacy in learning) in the literature. The close relationships of such type of beliefs with attitudes are also discussed by some researchers. Constructing a model that investigates these relationships by considering theoretical and empirical evidences can empower researchers to discuss these relationships more comprehensively.

Purpose: The purpose of this study is to explore the relationships among Turkish high school students’ scientific epistemological beliefs, self-efficacy in learning physics and their attitudes toward physics.

Sample: A total of 632 high school students participated in this study; however, 269 female and 229 male (a total of 498) high school students’ data were used.

Design and methods: Three distinct instruments that measure scientific epistemological beliefs, self-efficacy in learning physics and attitudes toward physics were combined into a unique questionnaire form and it was distributed to high school students. To explore the relationships among these variables, structural equation modeling was used.

Results: The results showed that scientific epistemological belief dimensions uncovered by the nature of knowing (source and justification) significantly and positively related to both self-efficacy in learning physics and attitudes toward other important physics dimensions. Additionally, self-efficacy in learning physics significantly and positively predicted attitudes toward multiple physics dimensions (importance, comprehension and requirement). However, epistemological belief dimensions related to the nature of knowledge (certainty and development) did not have significant impact on self-efficacy in learning physics or attitudes toward physics.

Conclusions: This study concludes that there are positive and significant relationships among Turkish high school students’ scientific epistemological beliefs, self-efficacy in learning physics and their attitudes toward physics.     

Problem-solving in collaborative game design practices: epistemic stance,affect, and engagement

ABSTRACT

This article explores children’s development of problem-solving practices through multimodal engagements in digital activities. The study is based on analyses of a video recorded peer group activity in which two children, within the context of a project on computational thinking using the software Scratch, collaboratively work to solve a coding problem. Drawing on work on epistemics-in-interaction and the cooperative and transformative organization of human action and knowledge, the analyses focus on the interactional strategies that the children use to establish, sustain, and develop knowledge within the peer group and the role of affect in the unfolding organization of actions. By analyzing the multimodal cultural production in children’s interaction with digital technologies, it is shown how children learn creative and artful skills, thus positioning them as consumers as well as producers of media.     

Student views regarding online freshmen physics courses

Background: Nationally, many public universities have started to move into the online course and program market that was previously associated with for-profit institutions of higher education. Public university administrators state that students seek the flexibility of online courses. But do students want to take courses online, especially freshmen-level science courses perceived to be difficult?

Purpose: This study investigated student views related to the potential of a physics course they were currently enrolled in being offered online.

Sample: This study took place at a large, public, mid-western university and involved students enrolled in either the first or second semester of a face-to-face flipped physics course for engineering technology majors.

Design and methods: Discussions with students during the semester about their online course experiences and expectations were used to develop the concourse and subsequently the Q sample to perform a Q methodology study about students’ views regarding taking physics courses online. Additional statements for the concourse and Q sample were taken from communications with administrators at the university. In this way, the statements sorted by the students included those from students and those from administrators. Factor analysis of the Q sorts resulted in three factors, each representing a unique perspective. Interpretations of these perspectives included the analyses of the Q sorts, the researcher’s interactions with students and administrators, and students’ written responses regarding their previous online course experiences and their sorting decisions.

Results: Three unique student views emerged were named: keeping it real and face-to-face, Online could be ok depending upon the course and instructor, and Online not for STEM classes. Consensus among the views is also discussed.

Conclusions: Overall, students’ views are negative concerning having physics courses, including labs, online and those views conflict with statements expressed by administrators regarding students’ desires for online courses at the university.     

How can simulation help with learning project work skills? Experiences from higher education in Finland

ABSTRACT

Background: Effective project management and project work skills are important requirements in higher education and many other work place settings. Simulation-based learning, with its use of simulated scenarios and environments, may be a helpful way of supporting skill development. However, much more needs to be understood about the possibilities and challenges that can be involved in the application of this method of learning and teaching, from the perspectives of the learners.

Purpose: This exploratory qualitative study sought to describe university lecturers’ experiences and views of simulation as a method of learning and teaching project skills. The simulation method was tested in Finland, in the context of the national Research and Development Expert Coaching Programme, which was developed for the staff of the Universities of Applied Sciences.

Research methods: Data were collected via a questionnaire with two open questions, to which total of 12 multi-professional participants, all lecturers from Universities of Applied Sciences, were asked to respond in essay form. The data was analysed using inductive content analysis.

Results: Overall, our analysis suggests that participants felt that simulation-based learning was suitable for learning project work. According to the participants, the method helped them learn concrete project work skills, identify and manage challenging situations and promote dialogical sharing between professionals.

Conclusion: The results indicate that simulation can be used to promote project work competence of both new and more experienced project workers in various fields. It is suggested that the method is suitable for both initial and continuing education.     

Philosophy,thought experiments and large context problems in the secondary school physics course

In this paper it is argued that scientific thinking in physics involves the progressive clarification of the relationship between mathematics and physics, as well as the clarification of scientific induction and deduction. Furthermore, the framing of theories and the working out of their consequences involve the exercise of the imagination. One locus of scientific imagination is the thought experiment, primarily understood as a mental device that helps explicate concepts and principles, and unravel paradoxes.

A sound curriculum in physics, however, must also be based on broad principles of education. These principles are first stated and then it is argued that in conjunction with what we have said about scientific thinking we should teach physics in terms of contexts of inquiry. These contexts relate to questions, method, problems, experiments, history, and the large context problem itself. Here we find the clarification of induction and deduction, as well as the proper placing of the thought experiment.

In the appendix it is shown how this contextual approach can be used for the teaching of kinematics. It is claimed that when we teach within the contexts of inquiry, physics is liberated from a specifiable method, and becomes historical, relevant, alive, human and exciting.     

The silent voices: Pupil participation for gender equality and diversity

ABSTRACT

Background: The international body of research on student voice concludes that active pupil participation has multiple positive effects on the work environment and learning for pupils. In a large study on gender equality and diversity work in Swedish schools, it became evident that pupils wanted to be active participants. However, pupils considered that their wishes were, to a large extent, ignored. Therefore, it is important to try to understand this further by investigating pupils’ perceptions of their experiences.

Purpose: The purpose of the study was to explore how discourses of participation and power are practised, not practised, and materialised, by focusing in-depth on pupils’ representations of gender equality and diversity work within a small sample of Swedish schools.

Methodology: The study is based on data from 10 focus group interviews with 43 pupils from 4 different schools, 2 compulsory schools (pupil ages 6–15) and 2 upper secondary schools (pupil ages 16–18), in Sweden. The thematic analysis utilised a gender perspective anchored in a critical policy analysis approach.

Analysis and Findings: The analysis of focus group data identified three pupil representations of gender equality and diversity work: a onetime occurrence, longing for participation and the (un)fair teacher. These representations were derived from and intertwined with discourses on pupil participation and power. Three sub-discourses were found within the discourse on participation and power: normative barriers to participation, structural barriers to participation and openings in the barriers to participation. The first two sub-discourses support the maintenance of unequal power relations between adults and pupils, while the third challenges these power relations.

Conclusions: Our study suggests that no substantial levels of participation or power among the pupils were represented at the schools. Instead, the analysis visualises pupils as expressing powerlessness and disengagement. However, the discourse Openings in the barriers to participation, together with pupils’ democratic abilities, has the potential to enable change and the development of pupil participation in schools.     

Broadening our lenses of perception to advance learning: An introduction to multilectics

In Broadening our lenses of perception, I address the need to assess students through multiple lenses rather than through the dominant lens of standardized tests. I propose what I call multilectical lenses to provide multidimensional pictures of poor students of color; these highlight student skills and knowledge that tests disregard. Multilectics employs multi level analysis, sound and images to analyze the gestures and voices of students during classroom activities. In combination with student writing, the data produced by multilectical practice provide a rich foundation for advancing the academic achievement of our most underserved students.     

Undergraduate Research in Quantum Information Science

Abstract

Quantum Information Science (QIS) is an interdisciplinary field involving mathematics, computer science, and physics. Appealing aspects include an abundance of accessible open problems, active interest and support from government and industry, and an energetic, open, and collaborative international research culture. We describe our student–faculty joint work in QIS that has led to many student co-authored papers in research journals. We address program structure and funding, and describe the work performed by our students.     

Making practical work work: using discussion to enhance pupils’ understanding of physics

Background: Practical work is widely seen as a necessary part of a good physics education, but convincing evidence that it impacts positively on pupils’ learning is scarce. Recent work suggests the use of talk and discussion might hold the key to making practical work more educationally productive.

Purpose: The research question that this study aims to answer is: Can the use of targeted discussion improve learning through practical work?

Sample: The study took place in a medium-sized (700-pupil, Years 7–13 (ages 11–18)) mixed-gender independent (fee-paying) day school in southern England. It is academically selective and public examination results are above the national average. The activities were carried out with three teaching groups (n = 73) with a fourth being used occasionally for comparison purposes (giving n = 97).

Design and methods: Pupils were given a number of practical tasks – some from the usual scheme of work, some devised for this project – and given specific time to discuss with a partner the various aspects of the practical such as predictions, devising methods, problem-solving, conclusions or explanations of phenomena. Questionnaires and booklets were used to gather pupil responses. Some audio recording and analysis of pupil-pupil discussion was also done.

Results: There was evidence from booklets pupils filled in during the practical that prescribing the use of discussion at various points in a practical task led to improved outcomes, particularly on the more cognitively challenging tasks. In particular, discussion was seen to turn incorrect responses into correct ones much more frequently than the reverse. In a later exam, pupils who had participated in the discussion activities performed better than a control group on questions which directly related to practical concepts, but performed similarly on the remaining exam questions.

Conclusion: Evidence gathered suggests a more nuanced pattern than that reflected in previous literature: that discussion during practical work can impact positively on pupils’ understanding of ideas related to practical work, but does not necessarily have a positive impact on their wider understanding.
