iStage workshops at GIREP Conference in Wrocław July 6-10

GIREP, the International Research Group on Physics Teaching, regularly arranges international meetings of concerned individuals to encourage the renewal of Physics teaching. Last July the GIREP Conference 2015 took place at the University of Wrocław in Poland.

Maria Dobkowska from Science on Stage Poland and Gerhard Rath from Science on Stage Austria were taking part at the conference and presented two workshops based on the brochure iStage 2 to an international group of participants. The idea of the iStage booklets raised a great amount of interest and there was a strong demand on the brochures.

In her workshop Maria Dobkowska presented a classroom practice on 'Oscillatory motion – visualization and analysis': Using accelerometer applications on their smartphones the participants collected data on oscillation, transformed the save data and step by step learned how to create their own graphs. In the acoustic part of the workshop the participants calibrated their smartphones and measured the different volume of sound spectra created by music instruments, replayed voices of birds and cicadas. By using rotating whistles the participants were also shown how to observe the Doppler effect with their students in a simple and effective way.

Gerhard Rath presented a workshop on distance measurements with smartphones. He showed the participants how to use various apps in order to measure an unknown distance. In this way students can try to investigate for example the height of the sun and compare the results with given values or other results of measurements. In another part of the workshop Rath demonstrated the participants how to record a movement by using a smartphone, how to draft a acceleration diagram and analyse the motion.
