Group interactions in science practical work

This study explored the interactions of a highly motivated group of students doing traditional practical work in science. Interest focussed on the social construction of understanding and how this could be described. Despite considerable collaboration in constructing an understanding of the task the students rarely focussed on the concepts the practical work was intended to illustrate. Collaboration was described in terms of social behaviours and discourse moves which supported the use of cognitive strategies. Specializations: science practical work, collaborative group work, role of language. Specializations: science teacher education, conceptual change, learning environments, science reasoning.     

Mathematical discussion and perspective drawing in primary school

The aim of this paper is to analyse the functions of semiotic mediation in a long term teaching experiment on the plane representation of three-dimensional space by means of perspective drawing, that has been tried out from grade 2 to grade 5 in three different classrooms within the research project Mathematical Discussion. On the one side, drawing has a functional role in the overall development of the child; on the other side, perspective drawing has a phenomenological role in the genesis of modern geometry. The experiment aims at connecting (1) pupils' spatial experiences to the development of the geometry of three-dimensional space and (2) pupils' drawing experiences to the geometry of two-dimensional space, up to the mastery of early geometrical strategies of plane representation of space. Classroom activity alternates individual problems and classroom discussions orchestrated by the teacher. The paper is divided into several parts: after a brief introduction containing some contextual information (§§ 1, 2), the problem of the social construction of knowledge is addressed and some theoretical constructs mainly borrowed from the Vygotskian school are elaborated (§ 3); then two analyses of the experiment are made, according to the motives of activity (§ 4) and to the sequence of actions (§ 5); finally the role of semiotic mediation in the whole experiment is analysed (§ 6); in the final section (§ 7) some results are recapitulated and compared with the literature on the teaching and learning of geometry and the function of semiotic mediation is discussed with reference to the other distinctive features of the teaching experiment.     

The assessment of practical work in school science

In this paper we provide an overview of the literature on understandings of drop out/opt out from science, technology and mathematics (STM) higher education programmes. After outlining the literature on students leaving higher education programmes in general, we then explore the research on drop out/opt out from STM programmes in particular, with an emphasis on research since 2000. We show that most of the research focuses on overcoming deficits in students' prior knowledge, but that a more specific focus on identities as an analytical framework for understanding young people leaving STM higher education programmes is also emerging. We show that it is important to shift from considering drop out as an individual problem for the student to regard it as a feature of the relationship between students and their study programmes. In the same way, measures to increase retention rates must shift from focusing on individual student adaptation to studies addressing institutional change. However, this change is difficult since it is entwined with fundamental conceptions of science and teaching.     

The interactive whiteboard in primary school science and interaction

The findings of the research literature about the necessity and contribution of Interactive Whiteboards (IWB) are not unequivocal and are sometimes contradictory. The study aimed to examine the interactive attributes in lessons with an IWB and the students’ attitudes. Methodical structured observations of 26 science lessons were conducted in elementary schools in Israel. The results showed that the teachers frequently used the diverse IWB tools, but most of the learning took place in frontal, whole class learning. Most of the interaction was under the teacher’s control and the dialogic interaction was limited. The attitudes of 62 pupils showed that despite already studying with an IWB for five years, their enthusiasm did not wane. They even claimed, in contrast to the observation findings, that the IWB contributed to active learning and interaction in the class. The research findings raise fundamental questions regarding the place of the IWB in promoting interaction in the class and on the necessity to promote the teacher’s pedagogic concept in order to increase class interaction.     

Multiple influences: Latinas,middle school science,and school

This paper describes the multiple school and school science experiences of eight Latina students of Central American descent in a tracked, urbanized, middle school setting. Framed by a sociocultural perspective, I describe how eight seventh and eighth grade Latino girls interacted with school science. Implications for the concept “science for all” are discussed.     

Improving progression and continuity from primary to secondary science: Pupils' reactions to bridging work

This article reports research from a project set up to implement ‘bridging work’ in science in England. Group interviews of 59 pupils in Year 6 (at the end of primary school) and 48 pupils in Year 7 (at beginning of secondary school) were carried out after pupils had completed bridging work. Twenty‐six of this sample were the same pupils. Semi‐structured interviews were carried out in groups to ascertain: their aspirations and fears concerning secondary science, their reactions to bridging work and their memories of investigations. Year 6 pupils were positive about studying science at secondary school and remained so after transfer. Pupils' reactions to bridging at both ages were very positive. Findings challenge recent critiques of bridging. The lack of progression in pupils' communication about the variables and findings from investigations suggest that the planned progression of work was not recognized by some teachers. Bridging work alone may not guarantee improved progression and continuity in science, but as part of a carefully planned and structured programme of collaboration it has merit.     

Student gender, school size and changing perceptions of science learning environments during the transition from primary to secondary school

This study investigated students’ perceptions of the generalist learning environment of the primary school compared to their perceptions of the specialist science learning environment of secondary school. The role of student gender and change in school size as influencing factors on changes in students’ perceptions across primary to secondary transition were especially considered. The same students’ perceptions of the learning environment were collected in the final stages of primary school and again after their initial term in secondary school. Insights were gained into how students’ perceptions of learning environment changed during their first exposure to specialised science learning environments and teachers, and how these changes in perceptions during transition depended upon school size and student gender. Both school size and student gender were found to be influencing factors for changes in some learning environment dimension perceptions.     

Culture, food, and language: Perspectives from immigrant mothers in school science

The article explores the role of immigrant parents in middle school science as both teachers and learners as part of an urban middle school curriculum, the Linking in Food and the Environment (LiFE) program. The curriculum engaged parents as partners with science teachers to teach science through food. Over a 2-year period, parents attended a series of bilingual workshops, collaborated with classroom teachers, managed activities, guided student inquiry, and assisted in classroom management. The following study analyzes the role of culture, language, and identity as four mothers navigated their position as ‘insiders’ in a science classroom.

Students' perceptions about science: The impact of transition from primary to secondary school

As students move through school, attitudes to school in general, and science in particular, become less positive. This paper reports on a longitudinal study which mapped, from the students' point of view, the transition between primary and secondary school in Western Australia. The study focused on the subject of science, and used both quantitative and qualitative methods. During the transition, there is a considerable change in the organisation of the school, the curriculum and the teacherstudent relationship. Students in this study, especially the girls, were generally disenchanted with the teaching strategies used in their secondary science classrooms, and regretted the loss of the close teacher-student relationship of their primary school years. Their perceptions were that science in secondary school was not what they had expected, and this experience may have long term implications for their subject and career choices.

Implementing curriculum-embedded formative assessment in primary school science classrooms

The implementation of formative assessment strategies is challenging for teachers. We evaluated teachers’ implementation fidelity of a curriculum-embedded formative assessment programme for primary school science education, investigating both material-supported, direct application and subsequent transfer. Furthermore, the relationship between implementation fidelity and teacher variables was explored. N = 17 German primary school teachers participated in professional development on formative assessment, N = 11 teachers formed a control group. Teachers’ implementation fidelity was evaluated via classroom observations student ratings and an analysis of students’ workbooks, focusing on the frequency and quality of intended formative assessment elements (assessments, feedback and instructional adaptations). Regarding direct application, treatment group teachers’ implementation fidelity was high, with slight variations in quality. Regarding transfer, implementation fidelity was lower but teachers still implemented more formative assessment elements than the control group. Teachers’ pedagogical content knowledge and their evaluation of the formative assessment intervention were associated with implementation success.     

On the sovereignty of school rhetoric: Representations of science among scientists and guidance counsellors

This article sheds light on views held by actors who enjoy a certain degree of institutional legitimacy for “talking about science,” either as practitioners in the field of science or as guidance counsellors working with youths interested in having a science-related career. One hundred and seven scientists and technologists who worked either in a university or industrial research centre and 182 guidance counsellors working in high school settings participated in our survey; the main instrument for data collection was a questionnaire developed using the bank of items from “VOSTS.” Excepting a few aspects of the production of scientific knowledge, the predominant tendency suggests that both professional groups share a relatively similar discursive outlook on science—an outlook which presents a “family resemblance” with the usual school rhetoric on the exceptional status of science.     

Exploring the boundary between school science and everyday knowledge in primary school pedagogic practices

This paper explores the different ways that primary school teachers in Uganda navigate the boundary between school science and everyday knowledge in the context of a centrally mandated curriculum innovation. The paper is based on a study of the pedagogic practices of 16 teachers in eight Ugandan primary schools that were selected on the basis of having a track record of either high or low academic achievement in the public primary school‐leaving examination. The official primary school curriculum in Uganda prescribes that science be taught in an integrated form, including integration between science subject knowledge and everyday knowledge. The strategies that teachers in the study adopted in relating science to everyday knowledge was a key feature that differentiated between pedagogic practices in the high‐performing and low‐performing schools. In high‐performing schools, teachers recruited everyday knowledge as a resource for learning science as a specialised discourse; whereas in the low‐performing schools, acquiring everyday knowledge was viewed as an end in itself. The paper, then, considers the implications of differences in teachers' pedagogic strategies for the kinds of knowledge to which learners are given access.     

Curricular orientations,experiences, and actions: Graduate students in science and mathematics fields work in urban high school classrooms

We examined curricular orientations that graduate students in science and mathematics fields held as they experienced urban high‐school science and mathematics classrooms. We analyzed how these educators (called Fellows) saw themselves, students, teachers, schools, education, and the sense they made of mathematics and science education in urban, challenging settings in the light of experiences they brought with them into the project and experiences they designed and engaged in as they worked in classrooms for 1 or 2 years. We used Schubert's (Schubert (1997) Curriculum: Perspective, paradigm, and possibility. New Jersey: Prentice‐Hall, Inc.) four curricular orientations—intellectual traditionalism, social behaviorism, experientialism, and critical reconstructionism—to analyze the Fellows' journals, and to explore ways in which the positions they portrayed relative to curriculum, instruction, assessment, social justice, discipline, student involvement, teacher's role, subject‐matter nature, etc., shaped and were shaped by who they were before and during their classroom work. Our qualitative analysis revealed various relationships including: experientialists engaged in more open‐ended projects, relevant to students, with explicit connections to everyday‐life experiences; social behaviorists paid more attention to designing “good” labs and activities that taught students appropriate content, led them through various steps, and modeled good science and mathematics; and critical reconstructionists hyped up student knowledge and awareness of science issues that affect students' lives, such as asthma and HIV epidemic. Categorizing orientations and identifying relationships between experiences, actions, and orientations may help us articulate and explicate goals, priorities, and commitments that we have, or ought to have, when we work in urban classrooms. © 2008 Wiley Periodicals, Inc.

Group work in elementary science: Towards organisational principles for supporting pupil learning

Group work has been promoted in many countries as a key component of elementary science. However, little guidance is given as to how group work should be organised, and because previous research has seldom been conducted in authentic classrooms, its message is merely indicative. A study is reported, which attempts to address these limitations. Twenty-four classes of 10–12-year-old pupils engaged in programmes of teaching on evaporation and condensation, and force and motion. Both programmes were delivered by classroom teachers, and made extensive use of group work. Pupil understanding progressed from pre-tests prior to the programmes to post-tests afterwards, and results suggest that group work played a critical role. Organisational principles are extrapolated from the findings, which could be readily adopted in classrooms.     

Learning from group work in science

Abstract

This paper addresses itself to the question of how effective group work is in promoting ‘learning from others’. It follows an earlier report in which verbal interactions between pupils engaged in group work were analysed. The tasks attended to during the group work were all concerned with the planning of scientific investigations.

The findings obtained indicate that a significant amount of ‘learning from others’ occurs as the result of pupils being involved in group work: in the present case, about 40% of information points included in pupils’ independent written accounts had previously been contributed to the group discussion by other pupils. However, the accounts also contained information points that had not been mentioned during the preceding group discussions.

The extent of pupils’ achievement and ‘learning from others’ in group work appeared unrelated to their actual group behaviours, which suggests that even seemingly ‘inactive’ group members benefit from their involvement in group learning experiences.
