and a nuanced depth of conceptualunderstanding of the material.IntroductionThe idea of integrating science and art has existed for hundreds of years, and in fact a divisionbetween humanities and science has only emerged in modern times. Great historical scientists likeLeonardo DaVinci were also known for artistic skill. The project Thermodynamics in the Artswas developed as a classroom exercise to allow undergraduate students to explore thermodynamictopics intellectually and creatively.The importance of creativity in the engineering education seems clear as current students willjoin an engineering work-force that demands innovation. Prior studies indicate that engineeringstudents are creative,1, 2 and that creativity can play a role in

We decided to integrate this approach into our undergraduateNewtonian dynamics class to leverage technology, optimize active learning with instructorspresent, and reduce faculty tutoring loads. In this method of teaching, the in-class time isdedicated to active learning, while the lectures leverage technology to supplement in class timewith on-line videos.The lower levels of learning in Bloom’s taxonomy [2], such as remembering and understanding,are delivered to the students through on-line lectures. The higher levels of learning, such asapplying, analyzing, evaluating, and creating, take place in the classroom with the instructor as aguide. To achieve this, in class time is devoted to guided instruction

: A Public Research University PerspectiveAbstractThis paper describes an experiment at the University of California, Irvine (UCI)that uses a combination of technology and pedagogical approaches to improvelearning outcomes for engineering students while reducing course delivery costs.Like most public research universities, UCI faces the challenge of improvinglearning outcomes in the face of declining State and Federal funding. Thischallenge has many elements; 1) As class sizes increase, student participation ishindered and class enrollments often exceed classroom capacities; 2) A lack ofimmediate feedback on student learning hinders timely interventions that wouldotherwise help students succeed; 3) Operation of classes is burdened

Therefore, weneed a method for assessing problem complexity so that we can create problems in a controlledfashion that achieve the appropriate level of difficulty. Students and instructors were surveyed onproblem complexity for problem sets based on the following simple survey instrument based ona Likert scale. This provided a means of calibrating our results in terms of the level of difficultythat students will experience during problem framing. Please rate how complex (i.e., difficult) you think this problem is. □ □ □ □ □ 1 2 3 4 5Least complex

The objectives of this project are to engage a student: 1) to design a well-structuredHopkinson bar by means of fundamentals of mechanics and finite element simulation 2) to builda working prototype of the apparatus for future research activities; and 3) to develop high speeddeformation experiments for instructional purposes. The designed Split Hopkinson bar consistsof two metallic bars with a specimen placing in between, a striker assembly, an air compressor,an instrumentation and data acquisition system. The experiments for using the split Hopkinspressure bar are conducted as an impact is made by the striker on one of the bars, whichgenerates

impact of using these slides(and the attendant instructional approach) on student performance and perceived learning.Two student cohorts were considered: (1) the 2005 and 2009 classes (47 students), who weretaught by the first author using the traditional method; and (2) the 2010 and 2011 classes (42students), who were taught by the first author using the revised method. Student performancewas assessed by examining the Statics grade distributions in each cohort as well as the finalexam scores. (The same final exam was administered to each class.) In addition, perceivedlearning was assessed via questionnaires that asked the students to evaluate their proficiencyrelative to seven specific course learning objectives. Student grades in freshman

Introduction The geometric discontinuities on shaft are unavoidable due to some required functions.But geometric discontinuities will cause significant stress concentrations. Step shoulders withfillets, retaining-ring grooves and key seats in shafts are the typical geometric discontinuities. Inlots of mechanical component design textbooks[1,2,3], the stress concentration factors for thestep shoulders with different fillets on shafts are fully explored and presented by sets of stressconcentration factor

possible solution to a problem identified in therecent research literature: despite decades of efforts dedicated to the improvement of engineeringeducation, and despite the many advances that have been well-researched and are readilyavailable in the literature, the faculty are not readily adopting them because the time required todevelop them exceeds substantially the normal course preparation. There are several positiveindicators that the summer immersion program is working; however, it is still too early todetermine if it has achieved “systemic and sustainable change”, and if there is an effect onretention rates, graduation rates, and employer satisfaction.

While thetraditional TBL approach consists of Pre-Class Preparation (no in-class time), ReadinessAssurance (1-2 class periods), and Team-Application of Course Concepts (1-4 class periods), theapproach was adjusted to provide students with more guidance during the Preparation Phase (3-450 minute class periods), which in this work will also be referred to as the Basic KnowledgeAcquisition Phase due to its extended nature.

In thispaper the authors describe a different aspect of mathematical CAD software: the ability toperform symbolic manipulations. This latter feature of some mathematical CAD software can beexploited by engineering instructors to help emphasize conceptual thinking while reducingunnecessary frustration on the students due to long algebraic steps and other repetitive analyticalcalculations required in differentiation, integration, and minimization of mathematical formulas.With less time spent on evaluating integrals, performing complex differentiations, and solvingsystems of equations, more time is available for students to engage in higher-level

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.

Infact, this form of engineering technology has been implemented into phone applications, e.g.SoundHound, to in order to identify popular music. Since music can be analyzed as a timedomain signal, it provides a natural medium for exploring time domain signal analysis12.
