To ensure that the students were learning about technological principles outside ofrobotics, the mentors created Fun Research in Engineering Education (FREE) Fridays. OnFREE Fridays the students would visit the ISU campus and participate in engineering outreachactivities. The students participated in the following engineering activities: Virtual Reality Lab,spaghetti and gumdrop towers, Toying With TechnologySM (robotic egg drop), DNA extracting,Rebops (creating an animal using parent DNA), LEGO® Hotel, and Cybot and Oscar (realrobots built by the Computer and Mechanical Engineering Senior Design students).

Although her background is mainly on telecommunications systems, she has beenteaching classes to both electronics and telecommunication majors on Local Area Networks,Computer Networks Simulation and Modeling, and Wireless Transmission Systems. The topic ofVoice over IP (VoIP) is often addressed in her lectures and given as project topics to thestudents. For instance, the projects address the signaling protocols, bandwidth requirements andperformance of different audio encoders/decoders (codecs).Since December 2007, this faculty has

There were also no existing national K-12 school standards for teaching and assessing for cryptology and cybersecurity when we startedthe project in 2019.To make this curriculum engaging, supportive, and exciting for all students, we conceptualized,designed and implemented four interrelated components (Figure 1): (1) a web and Android appthat includes games, puzzles, simulations, and tools for students to learn about the content andpractice the skills; (2) a series of unplugged activities that reinforce the content and skills withthe teachers' guidance and usually

Overlaying across all modules is the idea of integrating math and science to illustrate the usefulness of those concepts in engineering applications. Keeping track of the Calculus I and General Chemistry syllabi, problems were created such that they reinforced concurrent concepts being presented in those classes. This emphasized the importance of

Bycarrying out a virtual experiment before starting every new section, these adapted notesemphasize that experiments of all kinds including those that are physical, virtual (computer) andmental can be used to define the analytical approach.
