ALTERNATIVE CONCEPTIONS IN THE STUDY OF NEWTONS LAWS THROUGH QUESTIONNAIRE TO STUDENTS OF THE CAREER OF ENGINEERING

The low conceptual level presented by students in the study of classical physics has led to a number of investigations in order to improve academic performance. Among the strategies we can mention the importance of knowing the alternative conceptions prior to teaching. The goal is to develop and apply our own test question pool to determine specific conceptual errors about Newton's laws and determine the conceptual level of 140 students in the first semester of engineering. The results reflected in the justifications of their responses show a low conceptual analysis about particle dynamics. Such is the fact that only 4% of young people respond correctly to the definition of force. This shows that in the classes the resolution of exercises is prioritize without taking into account the theoretical reasoning.
