Computing and Information Technology
Science and engineering courses, theory and practice, an example
In engineering subjects where many topics deal with theory and abstractions, it is challenging for students to fully understand and learn the concepts and apply them to solve given practical problems. As examples in classes in Systems Engineering as well as Signal Processing, Control Systems, and Electromagnetics (EM), to just mention a few, we have found it useful to supplement lectures with examples where some solutions are presented using software packages and simulations after theory and principles are presented in detail.. In the Fall we are trying to present examples in the electromagnetics class where given problems are solved using concepts learned in the class followed by results, graphical representations obtained using modern tools for illustration and graphical representation. These software tools are available in our engineering computer Labs and students can try these solutions outside of the classroom as well. It is useful at the start of the course to show what are applications of materials they will learn in the course. One useful example is wireless communications, e.g., cellular phone system, where for example antennas are used as transmitting and receiving systems for electromagnetic waves carrying information signals. In their next course they will also encounter applications of digital signal processing (DSP), for example digital filters, used in smartphones. As science and engineering educators are using more and more computer and information technology (CIT) tools in the classroom, it is important that these modern tools are used at the right place, right time to enhance student learning. One approach will be to first introduce students to concepts and science/engineering principles then use the software package to verify results and for simulations purposes. In the case of electromagnetics ECE course the topics in the first course include studying static and stationary electric and magnetic fields, time-varying fields, wave propagation, Maxwell’s Equations, and transmission lines. Additional topics including antennas and waveguides may be difficult to cover in a one-semester course, but some schools cover these in a second EM course. Especially for a one-semester EM course use of demonstrations, computer simulations, examples using practical applications, will enhance student learning and some will be encouraged to elect more advanced courses dealing with antennas, waveguides, and microwave engineering. At the conclusion of the course we will be collecting assessment data for achievement of student outcomes covered in the course and present some data during the Annual Conference.
