Examining Changing Attitudes in Secondary School Science

This study, carried out in England, examined the variation of attitudes towards science over the first three years of secondary schooling and with gender. The study in question was part of an evaluation of the “Lab in a Lorry” project, and involved 932 pupils completing a pre‐measure questionnaire containing items looking at six separate attitude constructs. From these data, two main patterns emerged; pupils’ attitudes towards science declined as they progressed through secondary school, and this decline was more pronounced for female pupils. These conclusions are largely in agreement with previous studies in this field. However, in examining separate attitude constructs, we were also able to identify that the sharpest decline occurred specifically for pupils’ attitude towards learning science in school. Furthermore, using linear regression, we identified that, as pupils progress through school, this construct becomes a greater influence on attitudes towards future participation in science. Therefore, we also concluded that learning science in school is a particular area that needs to be concentrated upon, if we are to improve children’s attitudes towards science. In the final part of the paper, we drew on interview data obtained from 44 pupils involved in the Lab in a Lorry study. Pupils’ comments in these interviews provided further insight into why pupils are “switched off” by school science. We drew out the most prevalent themes that emerged in the interviews, in order to provide further insight into why pupils do not enjoy science in school.

Developing Attitudes towards Science Measures

In this study, we describe the development of measures used to examine pupils’ attitudes towards science. In particular, separate measures for attitudes towards the following areas were developed: learning science in school, practical work in science, science outside of school, importance of science, self‐concept in science, and future participation in science. In developing these measures, criticisms of previous attitude studies in science education were noted. In particular, care was taken over the definition of each of the attitude constructs, and also ensuring that each of the constructs was unidimensional. Following an initial piloting process, pupils aged 11–14 from five secondary schools throughout England completed questionnaires containing the attitude measures. These questionnaires were completed twice by pupils in these schools, with a gap of four weeks between the first and second measurements. Altogether, 932 pupils completed the first questionnaire and 668 pupils completed the second one. Factor analysis carried out on the resulting data confirmed the unidimensionality of the separate attitude constructs. Also, it was found that three of the constructs—learning science in school, science outside of school, and future participation in science—loaded on one general attitude towards science factor. Further analysis showed that all the measures showed high internal reliability (Cronbach’s α > 0.7). A particular strength of the approach used in this study was that it allowed for attitude measures to be built up step‐by‐step, therefore allowing for the future consideration of other relevant constructs.

Learning In and From Science Laboratories

This chapter reviews research on practical work in order to demonstrate not only its potential but also its challenges and problems. A main point to be made is that practical work is not a static issue but something that has evolved gradually over the years, and which is still developing. The development relates to changing aims for science education, to developments in understanding about science learning, to changing views and understanding of science inquiry and to more recent developments in educational technologies. To demonstrate this, we start with a review along historical lines, looking back at practical work research over the last 50 years during three periods: (1) 1960s to mid-1980s, (2) mid-1980s to mid-1990s and (3) the last 15 years. Following from this review, the second part of the chapter elaborates four different themes that summarise the state of affairs of practical work at the beginning of the twenty-first century and points towards new possibilities: how is practical work used by teachers, the influence of new technologies, ‘metacognition’ as a factor in laboratory learning and the issue of ‘scientific argumentation’ as a replacement for ‘scientific method’.

Peer Argumentation in the School Science Laboratory—Exploring effects of task features

Argumentation is believed to be a significant component of scientific inquiry: introducing these skills into laboratory work may be regarded as a goal for developing practical work in school science. This study explored the impact on the quality of argumentation among 12- to 13-year-old students undertaking three different designs of laboratory-based task. The tasks involved students collecting and making sense of complex data, collecting data to address conflicting hypotheses, and, in a paper-based activity, discussing pre-collected data about an experiment. Significant differences in the quality of argumentation prompted by the tasks were apparent. The paper-based task generated the most argumentation units per unit time. Where students carried out an experiment, argumentation was often brief, as reliance on their data was paramount. Measurements were given credence by frequency and regularity of collection, while possibilities for error were ignored. These data point to changes to existing practices being required in order to achieve authentic, argumentation-based scientific inquiry in school laboratory work.

An empirical-mathematical modelling approach to upper secondary physics

In this paper we describe a teaching approach focusing on modelling in physics, emphasizing scientific reasoning based on empirical data and using the notion of multiple representations of physical phenomena as a framework. We describe modelling activities from a project (PHYS 21) and relate some experiences from implementation of the modelling approach in Norwegian upper secondary physics classrooms.

Beginning to Teach Chemistry: How personal and academic characteristics of pre-service science teachers compare with their understandings of basic chemical ideas

Around 150 pre-service science teachers (PSTs) participated in a study comparing academic and personal characteristics with their misconceptions about basic chemical ideas taught to 11–16-year-olds, such as particle theory, change of state, conservation of mass, chemical bonding, mole calculations, and combustion reactions. Data, collected by questionnaire, indicate that despite all PSTs being regarded technically as ‘academically well-qualified’ for science teaching, biology and physics specialists have more extensive misconceptions than chemists. Two personal characteristics, PSTs’ preferences for teaching as a subject ‘specialist’ or as a ‘generalist’ teaching all sciences and their self-confidence for working in these two domains, were assessed by responses to Likert-scale statements. Proportionately more biologists tend to be ‘super-confident’ generalists, while more physicists were specialists anxious about outside specialism teaching. No statistically significant relationships between personal characteristics and misconceptions were found, suggesting that chemistry may be being taught by confident PSTs with poor understandings of basic ideas. Furthermore, these data suggest that attending to PSTs’ personal characteristics alongside other components of a teacher’s professional knowledge base may contribute to creating more effective science teachers. The paper presents a novel way of considering PSTs’ qualities for teaching that offers potential for further research and initial teacher training course development.

Teaching and Learning Representations in Upper Secondary Physics

This study aimed at developing teaching material and strategies emphasising representations and modelling in upper secondary physics teaching. Representations are tools for modelling and understanding representations and how these can be manipulated is therefore believed to be a prerequisite for developing modelling skills. The study, accordingly, wanted mathematical representations and modelling to be an underlying focus in physics lessons. The study worked with physics teachers over 2 years to develop and trial teaching material and strategies, and in a third year tested this material in an intervention with experimental and control classes. Research questions asked what effects the material had on teaching, how teacher conceptualised the physics curriculum and teaching from using the material, and what influence the teaching had on students’ learning. The methodology included classroom observations with video recordings and note taking, questionnaires to teachers and students, analysis of teachers’ lesson plans, notes from discussions with teachers, interviews with teachers and an achievement test to measure learning. Student questionnaire data showed increased focus on representation in the experimental classrooms as compared to the control group, but no better effect in students’ achievement score in test for using representations. Significant differences were found between schools independently of being in the intervention or not, which makes us believe teacher and teaching characteristics were more important than the teaching material. Classroom observations, for example, showed that teachers varied in doing explicit or implicit teaching of representations, having a dialogical or authoritative style of teaching, and having an interactive or no-interactive communicative approach.
