PT Journal AU SIMBARTL, P HONZIKOVA, J KROTKY, J TI DEVELOPMENT OF TECHNICAL LITERACY BY COMPUTER-CONTROLLED MACHINES SO Trends in education PY 2020 BP 35 EP 42 VL 13 IS 1 DI 10.5507/tvv.2020.004 DE CNC; laser plotter; 3D printer; STEAM AB The article describes the use of 3D printers and laser plotter at elementary school. There are discussed possibilities of use and issues related to the actual use of these devices. The cost of these technologies is falling down, making it easier for elementary schools to afford it. RVP does not prevent to use it and a whole it is integrated into STEM or STEAM education. The piloting showed that children do not have a problem, after a short training, to create a 3D object in the basic program for 3D graphics. These computer-controlled machines offer also very good cross-curricular interconnection for elementary schools. However, each of these devices has its own specifics in use, which are highlighted in the article. ER
