Taxonomy [1]. This goal is oftenachieved by developing the student’s ability to solve problems [2]. Concepts are more deeply understoodby applying them to solve problems in a variety of contexts. Therefore, textbooks typically contain asignificant number of example problems and practice problems, instructors utilize class time to workthrough example problems, homework often involves the student practicing problem solving skills, and asignificant amount of tests and final exams are typically devoted to assessing the student’s ability to solveproblems. Instructors typically agree that homework is an effective tool to help students develop a higherlevel of understanding of the concepts on Bloom’s Taxonomy and to develop effective problem

For a largerproject, one semester may include research into the problem, design of a solution, validation of thedesign using appropriate software tools or calculations, and a report to the industry partnerdetailing the proposed design. Another semester may include fabrication of a working prototype,validation of the prototype, and a presentation of the final design and prototype to the industrysponsor. Each student is assessed using monthly progress reports and the team is assessed using acomprehensive report each semester, poster, and oral presentations.

With limited budgets, the challenge is to designsuitable lab experiments which are not too costly, particularly when multiple setups are requiredfor larger classes. Penney and Clausen [1] have recently written a very helpful book that providesmany relatively inexpensive fluid mechanics and heat transfer experiments. The experimentreported here is an adaptation of a sharp-edged orifice demonstration in the book, which wasoriginally described by Penney et al. [2

America’s Promise (LEAP) was able to identify many suchHIPs that are gaining attention [1]. In a subsequent report, Kuh found that students whoparticipated in these HIPs show that they were positively affected by these activities, asmeasured by the National Survey of Student Engagement (NSSE). It was found that these“deep approaches to learning are important because students who use these approaches tend toearn higher grades and retain, integrate, and transfer information at higher rates [2].” Thus,what we set out to do is to apply HIPs to a 300- level engineering course at a state collegelevel and gather data regarding its effectiveness, student reflections, and possible futureimprovements for better learning outcomes.HIPs in a Mechanical

Flipped and alternative classroom models have gainedin popularity in recent years and while the engineering classrooms in higher education havelagged behind their non-STEM colleagues in this process, the trend has continued to gaintraction over the last decade [1]. Adoption of alternative course models is due in part to thepromise that the flipped classroom design holds for engineering faculty to find a compromisebetween the long-venerated lecture format and the research-based instructional practices ofactive learning. In its idealized form, the flipped design allows instructors to maintain delivery ofcritical theoretical and background information by presenting this material to the students outsideof the formal classroom setting, thus

All ABET-accrediteduniversities maintain a design requirement per ABET learning outcomes B and C for the 2018-2019 requirements [1]. However, our emphasis on design is focused to obtain early engineeringprinciples such as hands-on understanding of force, energy and motion. We believe that thesethree principles are one of the most significant topics to cover at an early stage, as instruction inthese areas can lay the foreground to higher levels of Mechanical Engineering concepts such asstress, strain, tension, torsion, and more - all of which are implemented in the upper-level designcourses at NMT.Course Structure RedesignThe introduction to Mechanical Engineering course was

Mechanical Engineering Department at Seattle University was awarded a NationalScience Foundation grant to revolutionize the department. The department’s proposal centers oncreating a program where students develop strong identities as engineers. It leverages thedepartment’s small size and close ties with industry to create a culture of “Engineering withEngineers.” Details of the program changes in progress can be viewed as part of the 2018 and2019 ASEE NSF Grantees’ poster sessions and papers [1], [2]. The background section of thispaper draws on a work-in-progress poster presented at the 2018 ASEE Annual Conference thatreported on students’ explicit engineering identities as measured by the ESIS-2 [3].Background: Why Identity MattersIdentity

According to a survey done by the Business HigherEducation Forum in May 2012, 35% of four-year college students were math proficient but notinterested in STEM [7]. In another survey, 42.1% of college students were not proficient and notinterested, 15.2% were not proficient but interested, 25.4% were proficient but not interested andonly 17.3% were proficient and interested. The middle two categories “not proficient andinterested” and “proficient but not interested” contribute to approximately 41%.

The first draft of the Grinter report called for two models of engineering education, withmost engineering students being prepared for industry and the remainder given a more advancedscientific preparation [2]. However, most engineering schools, wanting access to governmentresearch funding, protested, leading to the final report calling for a single model with an increasedfocus on science.The Grinter report recommended that all engineers should gain a background in the sixengineering sciences of solid mechanics, fluid mechanics, thermodynamics, heat and

engineering courses involve problem solving, and solving problems requires thedevelopment of several types of knowledge and skills. From course to course, the kinds ofproblems that are solved and the specific knowledge and skills required can be very different.But across a wide range of courses we can define categories of knowledge and skills that arerequired for solving most problems. By referring to these categories while teaching, studying andpracticing, we can develop a framework for learning. This framework provides a location and astructure for storing important knowledge, making it easier to recall.Let’s call these learning categories the Seven C’s. 1.

students enrolled in this course are initially led throughthe derivation of an equation governing the motion of the system, which is a non-linear ordinarydifferential equation (ODE). However, because this derivation is based upon Rayleigh’s energymethod [1, 2], and because of the energy-conservation property of simple harmonic motion, theessential parameter characterizing the vibration can be determined from this equation without theneed to formally solve the ODE obtained (although courses on rigid-body dynamics and ODEsare prerequisites for this course). This important procedure is briefly outlined in the next sectionof this article.This derivation also provides an excellent opportunity for students to review and reinforce theirunderstanding of
