Excel as Tool for Modeling , Dynamic Simulation and Visualization ofMechanical Motion
One of the most important tasks in teaching of mechanics is to use a suitable method for developing of theoreticallyacquired knowledge. Drawing on her own experience, the author has found that the best method to be used is the system approach.System approach is closely connected to the modeling,computer simulation and dynamic visualization. Theory of the systems, modeling and computer simulation are disciplines with its own theory and research methodology. Modeling and computer simulation (M&S) can be understand as one of the most important method in teaching of mathematics and simultaneously can be use as suitable method for practical developing of theoretically acquired knowledge. Case study, described in the paper, presentspossibility of dynamic visualization of mechanical motion – trajectory of ballistic shot. The solution is demonstrated in MS Excel worksheet and chart. Key-Words:Animation, computer simulation, mathematical modeling, system approach, visualization.
Multimedia support of parametric modeling
Programs for technical modeling are used in almost every field or industry. We see them in technical industries as well as in our everyday life and even in areas where we would never expect to see them. It generally replaces the creativity and imagination of the designer, and in many cases it helps determine collision situations and points during the creation of new products. Multimedia has a significant on the effectiveness of teaching these software applications in the engineering study.
Modeling of a real situation as a method of the algorithmic thinking development and recursively given sequences
A method of developing students' algorithmic thinking is demonstrated in the paper first. This is followed by an example of a physical problem step by step modeling and several approaches to its solution. These approaches demonstrate possible interdisciplinary learning, which is considered to be a very important part of future teachers' education. Especially the relationship among physics, computer science and mathematics is introduced. Finally the benefit of CAS for explaining and visualizing recursively defined sequences is discussed.
