Electromagnetic Induction: a vertical path for conceptual learning
Full text linkUn percorso verticale di elettromagnetismo nel quadro del Design Based Research, progettando esperimenti originali, strumenti didattici e di analisi degli apprendimenti dalla scuola primaria all’università. Il Model of Educational Reconstruction (MRE) è stato il quadro teorico per l’attività di ricerca condotta in modo coerente. Uno specifico studio ed intervento di ricerca è stato fatto nell’ambito della formazione iniziale degli insegnanti di scuola primari
Magnetic field nature and magnetic flux changes in building formal thinking at secondary school level
No full textThe importance of the electromagnetism as topic itself and educational framework in which learn how to
master multivariable abstract entities require the development of organic learning path for high school
students. An empirical research done in the framework of a designed based research was performed in three
different types of high schools to look at the reasoning that an organic learning path constructed on the formal
construction of abstract entities promote in the students when the idea of the flux tubes representation is
introduced as the key element in the interpretation of the magnetic field representation. The learning path,
designed with an inquired based approach, provide to students the environment in which experimentally
explore physical quantities constructing formal entities able to represent their properties. Then, the providing
of challenging context, as the explanation of the processes of electromagnetic induction, allows to investigate
how students validate and/or extend their interpretative model based on the constructed formal entities
The IWB as a bridge between phenomea exploration and interpretation of electromagnetic phenomena in construction of formal thinking
Full text linkThe diffusion of the Interactive Whiteboard in schools is in continuous increasing, but, too often, it was simple used to catch students’ attention or transpose on the “big screen” the class activities. In this paper is described a pilot study regarding the development of a Module of Formative Intervention for Prospective Primary Teachers in which the IWB as the role of supporter for the creation of a powerful context in which developed formal interpretation of electromagnetic phenomena starting from the analysis of experimental situations
Pupils’ discussion to understand magnetic interactions
No full textThe construction process of the interpretative model provide by a particular
group of 10 year old pupils to interpret the magnetic interaction was investigated in
the framework of the CLOE lab. As a particular case study, the evolution of the group
discussion was analyzed to identify: 1) the anchoring milestones taken from the
phenomenological exploration; 2) the bridging reasoning that move pupils naïve
models from a local to a global interpretation of the phenomena; 3) the
argumentations and the feedback argumentations proposed to check, validate and
(eventually) falsify the proposed models. Experimentation was performed using the
typical approach of the CLOE labs by providing an informal environment in which
pupils explore the phenomenology of the magnetic interaction by means of simple
hands & minds-on experiments. The activity with pupils was divided in three phases.
The first one was devoted to the creation of resonances between the pupils’ everyday
experiences with (toy) magnets and the situations proposed. In the second phase, a
series of small experiments realized with everyday materials was proposed to
students: each experiment was related to a specific learning knot and it is introduced
using an inquired based approach. In the third phase the, the discussion phase, pupils
had to provide an explanatory exploration of the magnetic interactions seen. Data
were collected during the discussion phase using audio recording and snapshots of the
drawings done by the pupils to support their explanations
Reasoning and models of talented students on electrical transport in solids,
No full textA sample of 40 students, selected from the last two classes of Italian secondary schools to participate
in a school of excellence in modern physics, after measuring resistance as a function of temperature of
metals and semiconductors and Hall coefficient at room temperature, was engaged in conceptual exploration
of contexts related to the nature of charge, voltage, current and electrical resistance. Results
highlight that the construction of the connection between macroscopic phenomenology and microscopic
models concerning electrodynamics processes is not only a success in physics, but it is also a possible
way to address the widespread and persistent difficulties that students face during the building of the
interpretative models
The use of computers and multimedia in the italian kindergarten, primary, and lower secondary schools in results by EU project SECURE research on the use of computer in italian compulsory schools
Full text linkThe European Project SECURE, investigating the curriculum of mathematics science and technology,
provide a relevant set of date related to the actual situation of the scientific education in the base schools.
On the base of those data, the actual situation of the use of the ICT technology in the Italian school is
analyzed and addressed to highlight the main characteristics and the main critical points
Building Formal Thinking with Pupils on Magnetic Phenomena in Conceptual Laboratories
Full text linkDeveloping formal thinking and building conceptual knowledge as a background for formal interpretation of phenomena is one
of the main challenges in teaching and learning physics. In the context of the experimental exploration of the electromagnetic
phenomena, pupils’ conceptual referents and representations of the phenomena and their identification and exploration of
conditions to produce electro-magnetic interactions are investigated through semi-structured interview in the framework of
Conceptual Laboratories of Operative Exploration. The pupils construct global interpretations of phenomena starting from local
interpretations of the single experiments and synthetizing them by means of building the formal abstract entities
Inquiring 5 years old pupils on MST curricula
Full text linkThe analysis of the official documents of a Country is not enough to have a “real” picture
of the school curriculum in that Country. This analysis had to be flanked and integrated by
the results of the investigation of the acted curriculum implemented by the teachers and the
perception that the pupils have. With the aim to investigate 5 years old pupils’ perception
of the curriculum of mathematics science and technology, two strategies for collecting data
in kindergarten were implemented and experimented during the pilot phase of the
SECURE European Projec
