The Use Of STEM Approaches To Widen Formula Derivation Steps In Material Science And Engineering Programmes At Higher Education Institutions
Many complex formula derivation steps found within material science and engineering programmes are essential skill-developing activities that enhance students’ learning. However, most students lack the required mathematical knowledge to fully comprehend some of those derivation steps. This work developed a framework of clarifying some of the formula derivations steps by adding further mathematical steps that support the students’ constructive and cognitive learning. Some derivation steps were added to the derivations of the theoretical tensile strength model as well as the Maxwell’s and the Voigt-Kelvin models. The idea was not to disrupt students’ constructive or cognitive learning processes but to facilitate their learning since their ultimate aim is not to derive but to apply the steps of the modified derivations in solving other material science and engineering problems. The students benefited from the activities in two folds; firstly, they understood the reasons behind each derivation step and secondly, it improved their self-study activities by reducing their study periods. These activities provide a platform to widen STEM activities at higher education institutions. The ongoing work will look at other important formula derivation steps within material science and engineering that can enhance students’ learning.
