Constructing constructivism: how student‐teachers construct ideas of development,knowledge, learning,and teaching

This case study investigates the development of the understanding of constructivist theory among students in a Masters level elementary teacher education program within a particular course. The focus of the study is a seminar entitled ‘Advanced Seminar in Child Development’. The questions explored include: How do students’ ideas of teaching, learning and knowledge develop within the context of their experience in this course? How do they come to understand constructivism? What are their definitions of constructivism? What is the course of the development of this understanding? The nature of the students’ learning processes is examined through three sources of data: dialog journals, videotaped sessions and the instructor’s reflective teaching journal. The study looks both at student development and instructional practice to further understanding of how student‐teachers can learn to apply constructivist theory to their teaching and to understand the learning process, both within themselves and their students. Their development is placed in the context of Korthagen and Kessels’s model of teacher understanding and practice, and within a broader context of principles of practice that emphasize a belief in equity and social justice. The case illustrates how the way student‐teachers are taught theory can help them integrate their own ideas of learning and teaching with constructivist theory in order to think critically about their own practice in an ongoing developmental manner.     

Challenging normative assumptions regarding disengaged youth: a phenomenological perspective

This paper explores the experiences of 12 young people, all teenagers, who have chosen to attend alternative schools known as flexible learning options within the Australian context. Using a phenomenological approach, the study seeks to understand their experiences outside the normalised public discourse that they had ‘disengaged’ from mainstream school. A phenomenological approach is employed because of its potential to draw attention to predetermined assumptions about, in this study’s case, student disengagement, a concept commonly framed within a pathologised and deficit perspective. The study gives evidence for the utility of a phenomenological approach in providing insight into how macrosystem policy, such as a nationalistic neoliberal agenda, influences ‘schooling’ and subsequently students’ experiences with schools. The implications of this study with attention to the nexus between methodology and policy are discussed, especially in drawing attention to how phenomenology as a qualitative methodology provides a means of agency for the disenfranchised to challenge existing policy and public assumptions.     

Recent Conferences

Atomic theory or the nature of matter is a principal concept in science and science education. This has, however, been complicated by the difficulty students have in learning the concept and the subsequent construction of many alternative models. To understand better the conceptual barriers to learning atomic structure, this study explores the troublesome nature of this fundamental scientific concept. In order to illustrate the distinction of student understanding by threshold barriers, this study chose three particularly high‐achieving students from an original interview sample of 20 students who were selected from an introductory college chemistry course. The pre‐course and post‐course interview responses were examined and compared in detail. This study considers the concepts of ‘probability’ and ‘energy quantization’ to both describe the structure of the threshold of understanding students’ need to negotiate in their construction of the target model of atomic structure. In this respect, this study suggests atomic structure as a possible threshold concept for further study in science. Identifying the nature and structure of the threshold of understanding confronting students, and analyzing the troublesomeness of atomic structure, provides valuable information for understanding student learning difficulties, and insight into how they may be addressed.     

UNIVERSITY STUDENTS’ UNDERSTANDING OF THERMAL PHYSICS IN EVERYDAY CONTEXTS

Thermal physics is in the realm of everyday experience, underlies current environmental concerns, and underpins studies in sciences, health and engineering. In the state of NSW in Australia, the coverage of thermal topics in high school is minimal, and, hence, so is the conceptual understanding of students. This study takes a new approach at exploring conceptions of students with a qualitative analysis facilitated by NVivo complemented with reference to sociocultural ideas of learning. A 2-part pen and paper question was given to 598 first year university students of different educational backgrounds (and therefore physics expertise). ‘The Question’ was based on 2 familiar scenarios and required the selection of a concept first, followed by an explanation. The results showed that concepts were favoured based on a student’s everyday experience and their curriculum through high school, and some were more effective than others in making scientifically congruent responses. The reported thermal physics alternative conceptions were also examined in our sample, and students’ reasoning behind such conceptions indicate that some conceptions do not inhibit scientifically congruent responses whilst others do. The results implicate language and the everyday experiences of the student in the teaching and learning of thermal physics.     

Comparing children's and student teachers’ ideas about science concepts

Children and teachers may not think in the same way about particular science concepts. Such parallel lines of thought can compound children's confusion and misunderstanding as they learn science at primary school. The situation could be more acute when student teachers are teaching science, because of their limited experience of considering children's ideas. This paper investigates children's and student teachers’ ideas about certain science concepts: ‘animal’, ‘flower’, ‘living’, ‘force’ and ‘energy’. The ideas and understandings of 96 children and 168 student teachers were explored. Results showed that the student teachers and children had similar ideas about ‘flower’ and ‘animal’, whereas they evidenced very different responses to ‘living’, ‘energy’ and ‘force’. Implications for classroom practice are considered.     

Upper Secondary Teachers' Knowledge for Teaching Chemical Bonding Models

Researchers have shown a growing interest in science teachers’ professional knowledge in recent decades. The article focuses on how chemistry teachers impart chemical bonding, one of the most important topics covered in upper secondary school chemistry courses. Chemical bonding is primarily taught using models, which are key for understanding science. However, many studies have determined that the use of models in science education can contribute to students’ difficulties understanding the topic, and that students generally find chemical bonding a challenging topic. The aim of this study is to investigate teachers’ knowledge of teaching chemical bonding. The study focuses on three essential components of pedagogical content knowledge (PCK): (1) the students’ understanding, (2) representations, and (3) instructional strategies. We analyzed lesson plans about chemical bonding generated by 10 chemistry teachers with whom we also conducted semi-structured interviews about their teaching. Our results revealed that the teachers were generally unaware of how the representations of models they used affected student comprehension. The teachers had trouble specifying students’ difficulties in understanding. Moreover, most of the instructional strategies described were generic and insufficient for promoting student understanding. Additionally, the teachers’ rationale for choosing a specific representation or activity was seldom directed at addressing students’ understanding. Our results indicate that both PCK components require improvement, and suggest that the two components should be connected. Implications for the professional development of pre-service and in-service teachers are discussed.     

Students’ Alternative Frameworks and Teaching Strategies: a pilot study

Research has shown that students’ alternative conceptions in science are quite resistent to change, which indicates that the teaching strategies used are not appropriate and that new strategies should be implemented in order to promote conceptual change. This pilot study was carried out with 100 Portuguese 5th grade students and aims: (a) to investigate a teaching strategy geared to the students’ conceptual change, taking into account their misconceptions about scientific ideas; (b) to promote a better attitude towards science. The results of this study indicate that the teaching approach based on the pupils’ alternative ideas and that makes them reflect on their own work and ideas, seemed to increase learning of scientific concepts related to the topic ‘properties and corpuscular model of the air’ and consequently favoured conceptual change better than a ‘traditional’ approach.     

Conceptual Resources for Learning Science: Issues of transience and grain‐size in cognition and cognitive structure

Many studies into learners’ ideas in science have reported that aspects of learners’ thinking can be represented in terms of entities described in such terms as alternative conceptions or conceptual frameworks, which are considered to describe relatively stable aspects of conceptual knowledge that are represented in the learner’s memory and accessed in certain contexts. Other researchers have suggested that learners’ ideas elicited in research are often better understood as labile constructions formed in response to probes and generated from more elementary conceptual resources (e.g. phenomenological primitives or ‘p‐prims’). This ‘knowledge‐in‐pieces perspective’ (largely developed from studies of student thinking about physics topics), and the ‘alternative conceptions perspective’, suggests different pedagogic approaches. The present paper discusses issues raised by this area of work. Firstly, a model of cognition is considered within which the ‘knowledge‐in‐pieces’ and ‘alternative conceptions’ perspectives co‐exist. Secondly, this model is explored in terms of whether such a synthesis could offer fruitful insights by considering some candidate p‐prims from chemistry education. Finally, areas for developing testable predictions are outlined, to show how such a model can be a ‘refutable variant’ of a progressive research programme in learning science.     

The more things change …: Re-discovering stubbornness and persistence in school-university collaborations

This paper examines some intersections among school literacy events and practices, identity formation, and the institutional practice known in the US as tracking. During a year‐long, critical ethnographic study to examine how a team‐taught, interdisciplinary curriculum impacted the development of students’ literacies, it was found that not only the literacies, but also identities, were being shaped and developed. Particular literacy events led the students to perceive that they were being encouraged to think of and comport themselves in distinct ways, based on their status as ‘honours students’. Classroom practices created a culture of privileged performativity for the students through which they came to perceive that recognition as an ‘honours student’ had less to do with deep, intellectual, and critical understanding and communication of important ideas than with the ability to perform in specific, rather superficial ways. For the participants, ‘honours’ identity was tied discursively and materially to a set of constructs that stemmed from competing and contradictory views about how one becomes an ‘honours student’. Key literacy events and practices through which ‘honours’ identity was recruited and enacted were inherently undemocratic, despite the teachers’ stated commitment to democratic pedagogies.     

Refining a learning progression of energy

ABSTRACT

This paper presents a revised learning progression for the energy concept and initial findings on diverse progressions among subgroups of sample students. The revised learning progression describes how students progress towards an understanding of the energy concept along two progress variables identified from previous studies – key ideas about energy and levels of conceptual development. To assess students understanding with respect to the revised learning progression, we created a specific instrument, the Energy Concept Progression Assessment (ECPA) based on previous work on assessing students’ understanding of energy. After iteratively refining the instrument in two pilot studies, the ECPA was administered to a total of 4550 students (Grades 8–12) from schools in two districts in a major city in Mainland China. Rasch analysis was used to examine the validity of the revised learning progression and explore factors explaining different progressions. Our results confirm the validity of the four conceptual development levels. In addition, we found that although following a similar progression pattern, students’ progression rate was significantly influenced by environmental factors such as school type. In the discussion of our findings, we address the non-linear and complex nature of students’ progression in understanding energy. We conclude with illuminating our research's implication for curriculum design and energy teaching.     

Implications of R.S. Peters’ notion of ‘cognitive perspective’ for science education

This paper discusses R.S. Peters’ notion of ‘cognitive perspective’, which, through careful reading, can be interpreted as a wider perspective resulting from an awareness of the relationships of one’s knowledge and understanding to one’s own life. This interpretation makes cognitive perspective a holistic notion akin to that of worldview, and also points to the possibility for students to experience a change of outlook on the world, as a result of learning science. Given the ongoing debate regarding the notion scientific literacy and the problems associated with it, the development of cognitive perspective can be considered the primary goal of school science education, as it provides an alternative way to think about what it means for a student to be educated in science. Such a goal, in turn, points to the importance of teaching for the (practical and emotional) significance of scientific facts and ideas, as awareness of such significance does not necessarily follow the acquisition of content knowledge and the application of the latter in everyday contexts. The paper also attempts to clarify the notion of utility of scientific knowledge, as an understanding of such notion is crucilal for understanding the implications of the development of cogintive perspective for school science education.     

Evaluating student assessments: the use of optimal foraging theory

The concepts of optimal foraging theory and the marginal value theorem are used to investigate possible student behaviour in accruing marks in various forms of assessment. The ideas of predator energy consumption, handling and search times can be evaluated in terms of student behaviour and gaining marks or ‘attainment’. These ideas can be used to examine student responses to dealing with assessments by examining a marks awarded/time-on-task curve. The non-linear, cumulative mark gain, as a Gompertz function, has implications for how students tackle continuously assessed projects as well as examination questions. The attainment of a student can be viewed in these general terms, as well as in specific aspects such as question ‘difficulty’ and mark gain in an examination answer. Prospect theory, from econometrics and psychology, can also be used to suggest ways in which students might tackle problems in examinations. The implications of this analysis are considered with respect to setting questions, criterion referencing of assignments and dealing with ‘troublesome knowledge’. The ideas can also be used to assist problems regarding mark fidelity and integrity as well as mark comparability.     

Making sense of education ‘responsibly’: findings from a study of student teachers' understanding(s) of education,sustainable development and Education for Sustainable Development

This article discusses findings from a tri‐country study of student teachers' understandings of the purposes of education, their conceptions of sustainable development and the task of Education for Sustainable Development (ESD). At its heart are case studies of 30 student teachers from Initial Teacher Education Programmes in England, Denmark and Germany (10 from each country). While they are diverse in their personal, professional and subject disciplinary backgrounds, and they work in a variety of school subject areas, all the students share the objective of becoming members of the teaching profession in the primary or lower secondary schools of their countries, and thus each one currently faces the additional challenge of understanding and responding to national, cross‐cutting policy initiatives on sustainable development and ESD. As interpretative research, the study catalogued and mapped similarities and differences in student teacher understandings, and identified those notions, thoughts and ideas that were meaningful to a beginning teacher's interpretations and sense‐making of key ESD concepts and tasks. The findings highlight the widespread importance of ‘taking responsibility’ and ‘having responsibility’ as key notions in interpreting their professional role and student learning in relation to ESD. An explorative framework developed during the data analysis suggests that in making sense of ESD, student teachers have recourse to one or more of at least four identifiable rationalities for ascribing responsibility to oneself or others, where each rationality articulates a different set of responses to questions about the prioritized locus of agency and the nature of the decision‐making process. The framework offers a critical and generative tool for stimulating debate in the field about policy and professional preparation and development and, in particular, the nature, processes and qualities of learning that are understood to ‘generate a sense of responsibility’, within the broader—and in the case of ESD—related quests of education and sustainable development.     

Changing views of teachers and teaching in Vietnam

In order for Vietnam to seek better international integration into an increasingly globalised world, the Vietnamese Government has launched educational reforms requiring teachers to adopt ‘Western’ constructivist pedagogies. This paper reports on an action research study in a Vietnamese teacher training institution which found that Vietnamese student teachers were willing to accommodate and accept change and were often very enthusiastic about the ‘Western ideas’ of teaching and learning, but that their unquestioning respect for the authority of their tutors remained firmly fixed. The data also showed that the students’ tutors had a relatively limited exposure to the ‘Western theories’ and their implications and therefore did not model or demonstrate the theories effectively. The paper draws on these findings to argue that the focus for transforming Vietnamese teachers’ practice should be on promoting the responsibility of teacher educators to introduce student teachers to new ideas about the processes of teaching and learning. This strategy is likely to be more supportive of student teachers’ development as it allows them to separate the processes of teaching from culturally dominant beliefs about roles which are part of their established identities.     

Beyond hard outcomes: ‘soft’ outcomes and engagement as student success

This paper questions current policy discourses that equate student success with hard outcomes like retention, completion and employment. It offers another view, one that uses ‘soft’ outcomes and student engagement literature to widen our understanding of student success. In the paper, we first draw on literature to explore student engagement, usually understood as a means to achieve success, and ‘soft’ outcomes as acceptable student outcomes, as success. We present possible indicators for these forms of success and a matrix of factors which influence such success. We then examine these ideas using data gathered from a project that investigated success as experienced by post-school foundation learners in Institutes of Technology and Polytechnics in Aotearoa/New Zealand. The findings suggest that the ideas have value. Finally, we identify some implications for teachers, arguing that, contrary to some current views, all four quadrants in the matrix are the business of teachers.     

Evaluating Secondary Students’ Scientific Reasoning in Genetics Using a Two‐Tier Diagnostic Instrument

While genetics has remained as one key topic in school science, it continues to be conceptually and linguistically difficult for students with the concomitant debates as to what should be taught in the age of biotechnology. This article documents the development and implementation of a two‐tier multiple‐choice instrument for diagnosing grades 10 and 12 students’ understanding of genetics in terms of reasoning. The pretest and posttest forms of the diagnostic instrument were used alongside other methods in evaluating students’ understanding of genetics in a case‐based qualitative study on teaching and learning with multiple representations in three Western Australian secondary schools. Previous studies have shown that a two‐tier diagnostic instrument is useful in probing students’ understanding or misunderstanding of scientific concepts and ideas. The diagnostic instrument in this study was designed and then progressively refined, improved, and implemented to evaluate student understanding of genetics in three case schools. The final version of the instrument had Cronbach’s alpha reliability of 0.75 and 0.64, respectively, for its pretest and the posttest forms when it was administered to a group of grade 12 students (n = 17). This two‐tier diagnostic instrument complemented other qualitative data collection methods in this research in generating a more holistic picture of student conceptual learning of genetics in terms of scientific reasoning. Implications of the findings of this study using the diagnostic instrument are discussed.
