Abstract:
Forming basic competencies in Mathematics, Science and Technology is one of the priorities of the current educational policies. The deficit of qualified personnel in Science, Technology, Engineering and Maths (STEM) implies the need to increase the motivation of young people to pursue careers in these fields. Interdisciplinary approaches, creating learning situations similar to those students will encounter later in their professional activities become more important in the organization of teaching activity. In this work we present ways in which we can exploit the GeoGebra software capabilities for creating visual and interactive computer models to support in-depth understanding of the significant issues in the study of oscillatory motions. Our approach is based on the constructivist principles of learning, so these models will be created by the students themselves. The student has the opportunity to enhance knowledge of Physics, Mathematics and Information Technology in an integrated educational process. We will present several ways of building, in a methodical approach, from simple to complex, of some interactive simulations of simple and compound oscillations, in the case of the elastic pendulum. The created models will support understanding of the influence of changing system parameters both in the simple harmonic oscillatory motion and also in the motion obtained by composition of parallel or perpendicular harmonic oscillations. Interactive applets created with GeoGebra support a deeper understanding of the phenomena, compared with static images or textual descriptions, allowing selective views, focusing successive on different components and features of the systems considered. At the same time, by involving students in constructing these models, using existing means of Information Technology, we will form computational thinking of students, a key component in education, especially for those who opt for a career in Science, Technology, Engineering and Maths.
