highereducationis well supported by multipleresearchers and educators (e.g., [2,7,8]. Alearning communityincreases studentinvolvement, builds connections through the
curriculum and extracurricularactivities,enhances student-student and student-facultyintellectual interactions andcollaborations, andexpands learning beyond the classroom [1]. As students participate in alearningcommunity that purposely structures thecurriculum to link courses or coursework,theyspend a substantial amount of time engaged incommon intellectual activities where theydevelop meaningful friendships and experience a great sense of belonging, which is vital forstudent retention [1].In this paper, we discuss the structure, interactions between, and effectiveness of three newcourses

engineering and to STEM concepts in general[1], [2]. The simplicity of the vehicle’s design makes it tractable to beginning students (frommiddle school on up) with little or no building experience, yet once students see it maneuver in apool they are immediately inspired to add capabilities. We have developed two systems toenable students to add capabilities to the Sea Perch as well as to enhance its utility as an oceanengineering and STEM teaching platform.As it is the Sea Perch is an excellent tool for teaching basic hydrostatics in a quantitative way.The displacement of the vehicle, its overall weight, and the distribution of weights can bemeasured and the centers of gravity and buoyancy can be calculated. Experience withhydrodynamics, the forces

,and stress calculations were performed to ensure the attachment was rugged enough to last over 5 years.  Figure 1: Wireless sensor node block diagramAverage power consumption (Paverage) of a wireless sensor node is given by16,17:Paverage  DPactive  1  D  Psleep (1)Here D = tactive/T is the duty cycle, when the sensor node is operating, Pactive and Psleep are the power usedby the WSN in active and passive mode, respectively, T is the operation period. One way the lowerPaverage is by reducing the duty cycle. The power supply subsystem must be able to provide both thetotal energy demanded during the expected node lifetime and the instant (higher level) power when thenode is

such as Strength of Material, Electronics, etc.IntroductionMassachusetts Maritime Academy (MMA) is one of the only seven maritime academies in USdelivering highly qualified graduates in marine engineering to the maritime industry [1]. Basedon the survey result from the office of career and professional services at MMA, the MMA’smarine engineer major students have 94% job placement within 6 months after graduation [2].The curriculum of the marine engineer major has course credit requirements and four co-oprequirements of sea terms aboard USTS Kennedy and commercial ships. In order to graduatefrom MMA, the students are also required to obtain United States Coast Guard (USCG) Licensefor a Third Assistant Engineer of Steam, Motor and Gas Turbine

them in a novel context while working as part of a team.This type of project engages students in a more active learning environment, focused on theintegration of prior knowledge to solve a complex engineering problem [1]. This allows studentsto develop deeper understanding in specific fields, a skill that is necessary to develop expertise inengineering [2]. Students work together in teams, preparing them for the collaboration necessaryin future employment. This also promotes cooperative learning, which has been shown toproduce better learning outcomes [3].Within fluids education, hands-on learning experiences are typically reserved for laboratorydemonstrations using large, expensive, or inaccessible equipment. While valuable for givingstudents
