Abstract
The Force Concept Inventory (FCI) test has been widely used to investigate students’ concept and understanding of introductory mechanics. It can be used to monitor the preconceptions, misconceptions and development of the students’ conceptual understanding on mechanics. The purpose of this study is to evaluate the entering engineering students’ prior knowledge in key concepts of mechanics in introductory physics using Concept Inventory Test at Technical University.Our findings have revealed absence of basic knowledge in the field of physics. Due to the fact that the testing revealed that students have problems with reading comprehension, graph interpretation, mathematical relationship, it is necessary for the future to pay attention not only to physics as a subject but also to skills related to maths and to overall engineering studies –to STEM education. Video analysis and simulations (VAS method) of problem tasks using interactive programme Tracker is one of the methods that considerably helps to form conceptual thinking and to develop manual skills and intellectual capabilities of students and finally at the same time eliminates misconceptions. Using videos and other multimedia aids affects in a positive manner the level of the students’ knowledge and understanding of physical phenomena.
Keywords: Conceptions, video-analysis, paired student´s t-test, F-test,reliability, validity, VAS method.
