TY - JOUR T1 - Chaos Physics in Secondary School A Material Applicable in Online Teaching A1 - Bajkó, Ildikó JA - Obzory matematiky, fyziky a informatiky Y1 - 2021 VL - 50 IS - 2 SP - 22 EP - 34 SN - 1335-4981 N2 - Chaotic systems are not only subject for researchers, but we all encounter them in our everyday life, when, e.g., mixing cream in coffee. This paper addresses the issues of teaching chaos physics in high school within both extracurricular framework, and by incorporating it into high school physics curriculum. The teaching material is based on mechanical processes and has been tested in different student groups. The module was specially elaborated to conceptualize some basic aspects of chaos theory, like predictability, chaos, complex and chaotic motions, irreversibility, determinism and mixing. The post-tests, administered to students after completing the module, have shown significantly higher scores on conceptual questions, as compared to the results of the pre-tests, indicating a deeper understanding of the enumerated concepts. The curriculum is suitable for online teaching, too. ER -
