Nevertheless, many students findways to cheat using solutions provided by sites such as CourseHero, or Cramster [1]. The goodgrades in homework give them the false impression that they are performing well in the class,until the exams come, and many are deceived. Instructors have long struggled to find ways tomake students learn in a more efficient way, and homework remains a big dilemma suggestingthat its practices should change. New teaching styles have been blossoming during the last fewyears, such as the flipped classroom where homework is no longer a work done at home[2].There

As enrollments increased in the program, the laboratory was re-designated as a separate offering from the lecture and optional—a student could enroll in the lecturefor 3 hours of credit and choose not to enroll in the additional 1 credit hour (3 calendar hours) oflaboratory. The lecture/lab combination was only offered every other year, as was typical for mostME electives in the small programs. Enrollments continued to swell to the point that an ongoing,annual lecture/lab could be offered starting in 2013. With an ongoing annual offering, the authorconsidered a more product-realization experience for the manufacturing lab than was historicallypresented.Other universities have shown a similar emphasis, from a curriculum

The Hierarchy is applied in such a way that if one’s more basic needs are not met, theless basic needs cannot and will not be fulfilled. Education does fit into this model and isrelatively high on Maslow’s Pyramid. Figure 1: Maslow's Hierarchy of Needs1 The pyramid’s foundation is physiological needs.

Asexample, in first order circuits (RC or RL) if we include AC excitations we are really dealingwith filters: low-pass, high-pass, band-pass or band-stop (reject) devices. These simple circuitsare examples of passive circuits & systems. With the introduction of operational amplifiers (Op-Amps) integrated circuits, we start description of so-called active filters.
