21 Main window for the least square approximation Š. Berežný, K. Budajová, E. Komová, H. Glaser-Opitz 201621

22 To summarize, the MATH application is designed to achieve several goals: Provide all calculation steps for each numerical method with easy to use graphical interface; Enable graphical visualization of calculated data as well as the option of exporting acquired data and graphs in suitable formats. Š. Berežný, K. Budajová, E. Komová, H. Glaser-Opitz 201622

23 Vernier system Š. Berežný, K. Budajová, E. Komová, H. Glaser-Opitz 201623 Vernier Software & Technology was founded in Portland, Oregon in 1981 in the home of David Vernier, a high- school physics teacher, and Christine Vernier, a local business manager.

24 Set of measurments Š. Berežný, K. Budajová, E. Komová, H. Glaser-Opitz 201624 Interface LabQuest and software,

25 Set of measurments Sensors (magnetics field sensor) Š. Berežný, K. Budajová, E. Komová, H. Glaser-Opitz 201625

26 Experiments Determination of kinematic viscosity Determination of gravitational acceleration Š. Berežný, K. Budajová, E. Komová, H. Glaser-Opitz 201626

27 Determination of kinematic viscosity Š. Berežný, K. Budajová, E. Komová, H. Glaser-Opitz 201627

28 Gravitational acceleration Š. Berežný, K. Budajová, E. Komová, H. Glaser-Opitz 201628

29 List of instructions for students Š. Berežný, K. Budajová, E. Komová, H. Glaser-Opitz 201629

30 To summarize, the main benefits to use of Vernier system are: It improves student understanding of science concepts. It supports engagement in higher order thinking skills, such as analysis, synthesis, and evaluation. It enables students to perform many new experiments and measurements not only in the laboratory.
