Physics Education in Science Training of Primary School Teachers

Our experience in physics training of primary school teachers is briefly presented together with a project we prepared for the teaching of science in primary school. We suggest for training teachers a practicum‐based strategy which requires that they initially carry out experimental activities designed for their pupils and express their ideas and needs. Usually they meet difficulties similar to those revealed by children and ask to explore in more detail the topics tackled in the laboratory activity. The aim of the proposed approach is to help teachers understand basic physics concepts and realise the importance of taking into account the pupils’ conceptions in the teaching process.     

A Three‐Dimensional Approach and Open Source Structure for the Design and Experimentation of Teaching‐Learning Sequences: The case of friction

We have developed a teaching‐learning sequence (TLS) on friction based on a preliminary study involving three dimensions: an analysis of didactic research on the topic, an overview of usual approaches, and a critical analysis of the subject, considered also in its historical development. We found that mostly the usual presentations do not take into account the complexity of friction as it emerges from scientific research, may reinforce some inaccurate students’ conceptions, and favour a limited vision of friction phenomena. The TLS we propose begins by considering a wide range of friction phenomena to favour an initial motivation and a broader view of the topic and then develops a path of interrelated observations, experiments, and theoretical aspects. It proposes the use of structural models, involving visual representations and stimulating intuition, aimed at helping students build mental models of friction mechanisms. To facilitate the reproducibility in school contexts, the sequence is designed as an open source structure, with a core of contents, conceptual correlations and methodological choices, and a cloud of elements that can be re‐designed by teachers. The sequence has been tested in teacher education and in upper secondary school, and has shown positive results in overcoming student difficulties and stimulating richer reasoning based on the structural models we suggested. The proposed path has modified the teachers’ view of the topic, producing a motivation to change their traditional presentations. The open structure of the sequence has facilitated its implementation by teachers in school in coherence with the rationale of the proposal.     

Understanding floating: A study of children aged between six and eight years

Graphs of real-time experiments are useful tools in science education; their intrinsic features allow innovative didactic approaches. The use of such images is spreading and is likely to become common classroom practice. This paper describes a study in which secondary school students were called upon to read and interpret documents containing images of real-time kinematics graphs specially designed to address common learning problems and to minimize iconic difficulties. Both novice students and those with a little experience of real-time experiments were involved. The overall didactic intentions of the presented documents were fulfilled. Some reading difficulties related to specific features were detected and are discussed. Suggestions are made regarding the acquisition of some specific capabilities that are needed to avoid misinterpreting these images and are of transversal value across several contexts. Finally, some implications for teacher training and class activities are discussed.     

Expectations of higher education students: a comparison between the perception of student and teachers

Higher education institutions are ever more interested in the development of tools that enable them to evaluate and manage the expectations of their students with the purpose of attracting and keeping them satisfied. This research compares what the faculty believes the students expect from a higher education institution with the expectations of students entering higher education. A quantitative study was performed with students from a higher education institution through the application of a questionnaire covering 32 different expectations. The perceptions of the faculty were also collected through the same questionnaire, suitably adapted. The results of the investigation demonstrated differences in thinking between students and professors, with 19 variables representing student expectations that showed statistically significant mean differences. In 13 variables the students had greater expectations than the faculty believed, while for six variables the faculty indicated higher expectations than the students declared. Identifying the existence of this gap in knowledge will allow the higher education institution to adjust its services to the expectations of students, leading them to greater satisfaction.     

Teaching Science in Elementary Schools: a Research Programme by the University of Pavia,Italy

Concept mapping is a technique used to provide a visual representation of an individual’s ideas about a concept or set of related concepts. This paper describes a concept mapping tool using a photograph association technique (CoMPAT) that is considered to be a novel way of eliciting children’s ideas. What children at 11 years of age know about particular concepts related to microbial activity is presented and discussed in relation to the effectiveness of CoMPAT as a tool to draw out their ideas. It is proposed that this tool could be used to explore ideas about this and other science concepts from children in other age groups, and where language may be a barrier to participation.     

Science education in the primary school: The problem of the initial training of teachers in Italy

A new strategy exploring the material aspects of photosynthesis (carbohydrate production) based on the generative learning model of Osborne and Wittrock (1985) has been developed. A teaching package entitled ‘Where Does The Wood Come From?’ has been trialled by an experienced and sympathetic teacher with a middle ability class of 26 fourth formers (14‐year‐olds). Seventy‐one per cent of the students acquired a view of photosynthesis as a carbohydrate‐producing process. This contrasts with the usual guided discovery strategy, where a food‐making view is the major outcome. Some novel techniques for implementing constructivist theory in the classroom (investigations, surveys, a self‐teach booklet, checkpoints) are described. Modifications to the generative learning model itself, especially its apparently sequential nature, are suggested.     

In‐service Training of Primary School Teachers: an Example with the use of Computers

An approach effective in helping primary school teachers master thermal phenomena is presented. It is centred on experimental activities of teachers and the use of computer simulations closely linked to their laboratory activity. Teachers’ ideas on the subject and their difficulties are reported jointly with remedy strategies.
