Our findings indicate that despite being developed to reflect the same curriculumframework, the five AM programs’ topical and complexity emphases varied widely. Overall,AM Competency Model content reflected higher levels of the Bloom’s Revised Taxonomy ofEducational Objectives, highlighting industry commitments to fostering analysis, evaluation, andcreation.

for manystudents. Especially as experiential learning becomes increasingly prevalent in curriculum designand further emphasized as an important educational tool, engineering technology is beginning togain traction as both a career path and a field of study, particularly among those seeking to spendless time in the classroom. For instance, in 2014, there were over 34,000 students who graduatedwith 2-year engineering technology degrees, versus 4,409 students who graduated with 2-yearengineering degrees, even though the number of graduates with 4-year engineering degreesremained substantially higher than those with 4-year engineering technology degrees [1].As this growth continues, it is increasingly evident that more research needs to be done

: Engineering Technology, Recruitment, Robotics, DesignIntroductionA 2016 report by the National Academy of Engineering [2] (NAE) sheds light on the status, role,and needs of Engineering Technology (ET) education in the United States (US). The reportclaims that in the US, “there appears to be little awareness of ET as a field of study or categoryof employment” [2, p. 4]. Factors leading to the general unfamiliarity of ET by most Americansare 1) there is substantially less ET versus engineering graduates per year 2) minimal formaloutreach and/or communications, especially with K-12 education systems, 3) and the ET brand isoften mismarketed and/or misunderstood [3]. There is no single effort, activity, policy, etc.which could fix all the factors

-space to another can be accomplished in infinitely many ways. These features allow asystem to be controlled. If a system needs to track an input, its output is measured and used asfeedback to construct an error function. By the application of the controller, this error is reducedas close to zero as possible. The manner, in which the error is brought to near zero, dictates theresponse of the system. Some of the methods used in control system design aim at minimizingintegral square, L2 norm, H∞ norm, etc. of the error [1]. One of the most common types ofcontrollers is a Proportional-Derivative-Integral (PID) controller. This approach of controlsystem design can be applied to any dynamic system.The teaching-learning system that is composed of a
