As a result, this antennas elective must incorporate pedagogically-selected background material such as differential operators and the differential forms ofMaxwell’s equations, skin depth, and reflection and transmission of plane waves at materialinterfaces. The course builds a solid foundation in antenna principles that serves studentscontinuing into advanced studies in graduate school as well as those entering industry aftergraduation. This foundation is accomplished by strategically selecting and modulating the

Institutions of higher education in the United States granted engineeringdegrees in the mid-2000s at a lower rate than in the mid-1980s.

However,the difference here is to have a structure to provide multiple formative feedbacks from theinstructor, the peers, and the student writing fellow (trained by the writing center) to helpstudents reflect on their weaknesses in writing through multiple interactions and assessment overa period of a semester. Furthermore, this vigorous writing-to-learn process is repeated in twosubsequent courses to ensure students proficiency in the process. In this format, the benefits ofusing writing-to-learn methodology have been expressed in many ways in the literature, such asimproved student writing, increased student learning and engagement, student-facultyinteraction, collaborative learning, and critical thinking to name

In engineering, the previous levels of the taxonomy culminate to the design of a component or system that invokes all previous levels of the taxonomy.

learning in this important path byemploying a customized version of experiential learning model. Kolb’s Model of ExperientialLearning [5] relies on the humanistic perspective that experience plays a critical role in learning.The four stages of the experiential learning cycle are shown in Figure 1a. The first stage in thismodel is concrete experience where a student or a team is assigned a task and learn by doing, notonly by watching or by listening to an instructor. The reflective observation is the step that thelearner reflects on the subject by communicating with the team or another individual. Theabstract conceptualization involves interpreting the experiment results. The final stage, activeexperimentation, is when the learner uses the outcomes
