Becoming a student again: Teacher training on ‘iStage 2’ in Cluj-Napoca

On 19th and 20th of March 2015 Damjan Štrus from Science on Stage Slovenia and Corina Toma from Science on Stage Romania gave a teacher training based on the new brochure 'iStage 2 - Smartphones in science teaching' at the Computer Science High School 'Tiberiu Popoviciu' in Cluj-Napoca, Romania. Three workshops were sustained in two days, with one aiming at students and two at the Physics and ICT teachers from Cluj County. About 60 teachers took part in the interactive and interdisciplinary workshops and for some hours became students again.

Damjan Štrus prepared a presentation of his school from Litija and taught the students and the teachers how to use the application named VidAnalysis(for Androids) in two cases: studying and analysing the free fall of a basket ball and an analyse of uniform movement of a pingpong ball in a glass tube. In a real-time experiment the participants made a video of the movement, imported it into the application and analysed it step by step in order to obtain a graph. The students and teachers also found mathematical equation to fit the graph.

Also presented were two devices (Štrus' and Tomas' Helmholtz coils) and how to use the compass application for measuring the horizontal component of the Earth’s magnetic field. Štrus and Toma explained how to build this kind of coils and provided an English manual instructions for participants. Finally Toma presented different applications for the height or distance measurements.The students were excited to use the applications and to find the confirmation that the graph for an accelerated movement was a parabola, like they already knew.
