mobile device, Gagné?s level of instruction, constructivism, sound

Nowadays, it is generally accepted that digital technology has the potential to influence, or better yet transform the education process. Digital technology not only enables data collection (through measuring, process modelling, simulation, calculation, etc.) and data processing, but also helps present it in new contexts. The learners can construct their knowledge by solving appropriate tasks in the digital environment. One of the possibilities is to use mobile touch deviceswhich, compared to desktop computers, feature various sensors and thus enable measuring, data collection and construction of new knowledge (during processing of results). The paper is aimed at the use of mobile touch devices in physics instruction.Noise measurement conducted in the vicinity of the school, on both busy and quiet streets, traffic observation, etc. not only enabled students to construct knowledge about sound and its properties, but also about the environment in the vicinity ofthe school. The instruction process was based on Gagné?s nine levels of instruction and guiding principles of constructivism ? experimenting and measuring provides specific experience that leads to construction of knowledge (terms) and furtherexperiments.
