Abstract:

Many first year university students in the science-related fields have a problem in identifying and applying the fundamental mathematical concepts that they have previously learnt in science problems solving (Freitas et al, 2004). First year undergraduate physics students at Central University of Technology, Free State (CUT) seem to be unable to apply their knowledge and skills of linear algebraic graphs in solving and presenting kinematics graphs. Mathematics is reported to be an essential tool in studying physics, i.e., it will be difficult to study Physics without the sound basics of Mathematics (Pietrocola, 2008). As a result mathematics is even called the “language of physics” (Redish, 2005). Physicists blend conceptual physics with mathematical skills and use them to solve and interpret equations and graphs (Redish, 2005). This study was prompted by the inability of first year students to apply and use the knowledge of algebraic linear functions and graphs in solving kinematics problems. Kinematics is part of basic and introductory physics and it requires mathematics understanding and knowledge. The study investigated students’ understanding and knowledge of algebraic linear functions and graphs among all first year students doing physics. The same investigation which required use and application of these mathematics knowledge and skills was conducted in kinematics equations and graphs. Students performed well in mathematics than physics meaning they do have mathematics knowledge and skills but could not apply it to solve kinematics problems. The study therefore investigated these students’ deficiencies and suggested possible learning and teaching practices in mathematics and physics that will try to alleviate these problems. Physics education researchers found that the learning of physics is often hampered by a lack of understanding of the underlying mathematical concepts, and that this may block students’ understanding of the physics and their ability to solve problems (De Mul, Batlle & Rinzema, 2004).
