Research based activities in teacher professional development on optics

The aim of this research is to understand how teachers take ownership of content given them in formative intervention modules and transform it into suggestions and materials for teaching. To this end a module on optics was designed for a group of kindergarten, primary and lower secondary school Teachers which sought to integrate meta-cultural, experiential and situated approaches with various context specific factors. The study investigated how teachers deal with conceptual difficulties in the module and how they adapt it to their school situations with data being gathered through a variety of tools. It emerged that the most difficult concepts teachers encountered at the formative stage were those they most often incorporated into their materials. The steps taken in this process of appropriation were then reviewed via a collaborative discussion among the teachers themselves on the materials they had produced

E-learning in teacher professional development in innovation and formative guidance on modern physics: The case of IDIFO master's programs

The professional development of in-service teachers is becoming an increasingly "hot" research topic internationally. Innovations in both methodologies and content are a challenge for schools wishing to respond to the demands of the knowledge society. The second level biannual IDIFO Master's Program, offered as project of the national plane for scientific degree (Piano Nazionale Lauree Scientifiche-PLS) by the Research Group in Physics Education of the University of Udine, in collaboration with 20 other Italian universities, provides teacher formation in modern physics and formative guidance to in-service teachers in Italian high schools and is now being run for the fourth time. Based on research into the teaching and learning of physics, it started in 2006 was activated in e-learning every second year. The course is wide-ranging (it is worth 165 CTS) and allows for customized study paths to suit the needs of individual participants, both regarding content and length of study period: single modules (worth 3 CTS) and an annual Specialization Course (15 CTS) are run alongside the Master's. The organization of the e-learning formation, carried out using uPortal, is as follows: analysis of physics education research materials; web-forum discussions of content and methods; the compiling of teaching materials, both collaboratively and in personal project work; doing experimentations (teaching intervention modules) in high school students, analizing and discussing online with peers and with professors-tutors-experts. The program has undergone continual revisions - based on feed-back and reflection on the overall outcomes of the formation - while retaining its original structure. Analysis of project work and of the dissertations presented in the final exams has demonstrated the contribution of e-learning formation to capacity building through: access to research material and proposals; peer debate; a critical review of traditional approaches. The flexibility of the formative model is a key element for its implementation nationally in a wide variety of situations. The commitment required of the participants, particularly in the first two versions of the program, while resulting in an excellent preparation, also prompted the course designers to create more flexible study paths in order to allow participants to complete their training in a number of stages following coherent pathways. The educational research on the Master's is not just a source of materials and training content, but also a context for what concern teacher formation. The analysis of participants' learning processes in each module - like that on quantum mechanics - revealed both the characteristics of an effective educational innovation formative model, and the part played by peer interaction on web-forums in building participants' integrated expertise both regarding content (CK) and its teaching/learning (PCK). An analysis of the school experiment written reports high-lighted the role of the Master formative path in the didactic design

Conceptual Labs for operative Exploration

In the perspective of the Model of Educational Reconstruction, designing new educational path require to gain new information on how students face the specific subject explored. At the PERG of Udine the main steps of the new educational paths were explored with pupils engaged in Conceptual Laboratory of Operative Exploration (CLOE) in informal learning contexts, where using different monitoring tools student spontaneous ideas as well their learning paths were explored and stimulated. In CLOE pupils discuss everyday life scenarios, recover their everyday and sensorial knowledge, as well as involve them in the challenges of explorations according to an IBL strategies. The CLOE lab are research based proposals of learning where explore how pupils build formal thinking, reflect on phenomena and construct models, reinterpret common everyday knowledge. The research focus is on the reasoning sequence, the ways in which knowledge is structured, the development of interpretative representations. The design characteristic of the CLOE labs are presented exemplifying it in the case of the CLOE on energ

Upper secondary students face optical diffraction using simple experiments and on-line measurements

A research-based educational path on diffraction of light was designed for upper secondary schools. Through the experimental exploration of the diffraction pattern produced by a laser beam incident on a single slit, students first analyse the diffraction pattern qualitatively, recognizing the global properties, then measuring with on-line sensors the light intensity vs position, constructing empirical relations between order and position of minimum, order and position of maximum, position and intensity of maximum. Making a wave hypothesis on the nature of light, a computer model based on Huygens' principle takes into account the intensity pattern of light. Experiments in school were performed with students, using inquiry based learning tutorial worksheets e pre-test, post-test. Positive learning indications of students emerged concerning the role of diffraction in everyday situations, and the general features of the diffraction pattern. The findings suggests that to produce an effective change in the model of light, students need to reflect extensively in the hypothesis at the base of their prevision and to by involved in deep in a modelling activity

High school students analyzing the phenomenology of superconductivity and constructing model of the Meissner effect

Superconductivity offers many opportunities to explore a relevant phenomenology interesting for students because perceived as a challenge stimulating the construction of models, activating a critical re-analysis of magnetic and electrical properties of materials, bridging science and technology. In the European projects MOSEM1-2, an educational path was developed on superconductivity for high school based on explorative experiments and on-line measurements concerning the Meissner and the pinning effects. Feasibility tests were performed in several Italian high schools with more than 500 students. A research experimentation carried out with 40 selected students, aged 17-19, was focused on the models they develop analyzing the Meissner effect using the field lines representation. Data were collected by the worksheets used by students and by the audio-tape dialogues in the group activities. A qualitative analysis of the students\u2019 answers, sentences, explicit reasoning and drawings was performed. The students learning paths show a progressive construction of models based on the ideal diamagnetic properties of superconductors, in which the concept of field has an important role
