The following paper describes the integration of a Formula SAE (FSAE) teamproject into a junior-level mechanical engineering experimentation course; it represents one ofnine projects in this course.The first half of the course is divided into modules that, for all students, progressively address: 1)the measurement chain and laboratory best practices using pre-existing experiments, 2) sensordesign, selection, and calibration, 3) statistical data analysis and uncertainty limits, and 4)technical communication skills. The second half tasks student teams to propose, design, build,and carry out an original experiment to an engineering problem they perceive can

Students at this stage need and expect to be motivatedby a more active and applied approach to EMAG than has been traditionally offered [2]-[4]. Atypical EMAG text emphasizes the mathematical theory of Maxwell’s equations for solvingproblems [5], [6]. While the mathematical approach excels in expressing relationships of EMAGconcisely, and lends tools for effective problem solving, treating the subject solely in this waycan leave the practical application context of problems unclear to students.

concept of buckling to civil engineering students.Introduction One of the most critical modes of failure in columns is buckling. When a long column issubjected to compressive force, the member might deflect perpendicular to the direction of theforce. Excessive deflection due to axial force might result to failure of the column. This mode offailure is known as buckling. When a member fails due to buckling, although the member isunder compressive force, but the failure is not due to lack of compressive strength of thematerial. Mainly, columns are designed for the buckling capacity. Figure 1 presents a concretecolumn experiencing buckling under compressive force.

Indeed, as their studies delve deeper into upper division courses, matters evolvefrom conceptually straightforward (i.e., statics) to more sophisticated (deformable) andpotentially abstract (thermodynamics). Challenges can arise correcting mistaken preconceptions,and linking perceptually-abstract mathematical formulas to real-world examples. Indeed, studies[1], [2] show that students value real life applications of the material covered, and that suchapplications contribute to a deep conceptual knowledge.Western Kentucky University offers programs in civil, electrical and mechanical engineering,presented with a focus on project-based learning.

Interactive Internal Combustion Engine Lab ProjectIntroductionLaboratory courses are an important part of undergraduate engineering programs. They arespecified in ABET’s list of student outcomes, they provide concrete experiences to reinforcelessons taught in lecture classes, and they give students some of the relatively few hands-onexperiences available in traditional engineering programs. However, while specific problemshave been difficult to identify, laboratory courses have for many years been a source ofdiscomfort and concern among engineering faculty. In 1983, Ernst outlined problems of focusand staffing that we still confront today [1]; Edward’s survey makes it clear that these concernshad not gone away by 2002 [2], as

During the ASEEconference 2018 in Salt Lake City, one of the authors attended a presentation [1], which inspired theauthor to publish the functional design achieved at Trine university. The authors also investigated anEngine dynamometer design [2] (published in 2002) which lacked focus on powertrain, which was pricedat around $3000 (in 2002 dollars). Another paper published in 2003 [3] also focused on enginedynamometer but the cost was not provided.Description of Design:The design of the dynamometer can be broken down into the following significant components: 1.

However, recent data[1] from three institutions and nearly 3000 students showthere was no statistically measurable lab benefit in boosting content mastery of physics.Students perform similarly on questions whose target content was reinforced by a lab activity ason questions whose target content lacked an associated lab activity. This result, althoughsurprising, makes a strong case for reexamining the purpose of labs and how they are taught. Another cause of the

Thisleaves them at a disadvantage both in terms of success in mastering the curriculum and level ofcompetitiveness for internships [1, 2]. As these students move through a typical engineeringcurriculum, a focus on abstract theory and mathematical concepts over physical applications andmeasurable observations will fail to give them the necessary hands-on experience, reducing thechances that the information will be retained over the long term [3]. Students who have specificlearning styles that favor physical experimentation and real-world experience are also left at

This state-ment is made in comparison to the opportunities made possible with remote labs. Consideringthat remote labs are represented as equipment that can solve location, time and capacity con-straints in laboratory education, this is surprising as many educational institutions suffer fromexactly such constraints. Existing literature shows that classroom laboratory solutions aremainly stand-alone solutions which require physical equipment and cannot be used synchro-nously among several institutions [1], [2], [3]. In this context, the VISIR system represents anexception [4]. The introduced VISIR

We collected and analyzed undergraduates’ lab reportsamples (n = 18) of the first lab and the last lab in order to identify the ZPD of lab report writingin the context of three entry-level engineering lab courses. We developed and used an inclusiveassessment rubric originated from the 2014 Writing Program Administrators OutcomesStatement for First-Year Composition (WPA 3.0 outcomes) to analyze recurrent patterns ofstudents' writing 1) in disciplinary meaning-making (i.e. organizational structures, reasoning, useof sources, etc.) and 2) technical communication (i.e. writing conventions, use of multi-modaldesign and/or quality of graphs/tables, etc.).

There is also weakevidence that shows greater affective gains in the treatment group. This shows that there ispotential for increasing student learning by studying how best to write laboratory manuals, andthat increasing reflection is a way to achieve that goal. However, it also shows that there aremany ways to increase reflection, and further research is required to identify them thoroughly.1 IntroductionLevel of inquiry refers to the specificity of instructions and

PowellElectrical and Computer EngineeringUniversity of Virginiahcp7ad@virginia.eduBackgroundEngineering is frequently perceived by many students as an entirely mathematical, abstract, andchallenging discipline. Students often perceive it as a trial and that the time expended oncoursework will lead to a financial or other gain after graduation [1]. At the same time, we areasking students to assimilate the theoretical understanding we are asking them to learn hands-onand experimental approaches and to develop the reasoning and decision-making skills sonecessary in their future careers. These significantly different skillsets are sometimes at oddswith each other, and it is difficult to balance the requirements of
students. The course materials developed includevideo components of lectures as flipped classes, and electronic clickers to engage students in theclassroom, and Moodle LMS as a vehicle for engaging students outside the class throughdiscussion sessions and accessing course materials such as video lectures.IntroductionThe objective of this paper is to demonstrate how an existing course was redesigned to a Flippedclassroom model using educational pedagogy of Fink [1] as e-learning is becoming popular. Thiswas implemented in a junior level civil engineering undergraduate classroom at a predominantlyundergraduate institution, at a California State University campus. This learning experience wasdesigned, with components webinars for background

The paper describes the experimental platform and gives preliminary results fromthe concept-inventory assessments. It was seen that the experiment helped to dispel some of thestudents’ misconceptions, but that further refinement of the experimental procedure may beneeded to address other conceptual errors about stress, strain, and the role of material properties,loading conditions, and beam geometry.1.

Students in laboratory courses often conduct experiments or complete demonstrativetasks by following “cookbook”-style instructions [2], [3]. This passive process directs thestudents’ focus towards completing prescribed steps (i.e., following a procedural recipe), butrarely challenges students to think critically about what they are doing and ought to be learningconceptually [3] - [5]. Although students may develop a practical understanding of process skillsthrough tangible, hands-on lab experiences, the effectiveness of cookbook laboratory exercises toimpart

The paperwill include details on the experiment and the guided peer review process, as well as logisticalsolutions to achieve the blind peer review.IntroductionThe ability to write effectively is a critical professional skill for the practicing engineer, and thus avital outcome for engineering programs.1 Though many programs require specific writing intensivecourses to build these skills, it is also important that students practice writing as an integral part ofthe broader work of engineering in design and laboratory courses.2 In particular, laboratory reportsare a logical vehicle to synthesize the work of experiment design, analysis, and technical writing.However, simply requiring students produce written reports is of marginal value if

In addition, schools that havestrong research faculty can enable an additional component where students and curriculumare informed by research methodologies as well as advancements in science andengineering, thus creating a mind set for innovation and critical inquiry.In this paper we present two cases of comprehensive summer programs where studentsworked in teams on research-oriented projects. The teams are composed of internationalstudents and worked with a clear objective to learn and contribute in creating new devicesthat may advance state of the arts within a social and economic context. The topics of

In order toreach this goal, students need to be exposed to projects that are related to real-world problemsthat include the typical complexity and uncertainty associated with these problems [3]. Studentsneed to learn how to frame a problem, analyze, design, manufacture and test it [4]. To meet theseneeds, educators need to revise and fit new contents to their courses, to shift the learningobjectives to focus on including design thinking and professional practice elements in courses.This has also been set as goal by the US Accreditation Board for Engineering and Technology(ABET
work environments [1]-[6]. Among them, most prominently are writing andpresentation skills. A parallel curriculum addressing these non-scientific/technical skills isusually a strong contributor towards these goals. Another tool generally more directly controlledby science/engineering faculty is using courses in the discipline, especially laboratory courses, toemphasize writing components and/or presentation skills. Lab reports can serve as a very goodtool to sharpen writing skills or, more extensively, the skills needed to produce a coherent, wellthought, well-written scientific paper or technical report.A more comprehensive approach to different paths and philosophies for the teaching of writingskills and its balance can be found in the
, labactivities sometimes become too focused on equipment rather than learning. Lee and Ceylan [1]note how student learning becomes passive rather than active when students follow cookbookapproaches with large pieces of equipment and no prior operating experience. From anadministrative standpoint, what is the point in purchasing and maintaining costly and largeexperimental equipment that students will only interact with for a few hours during their entireundergraduate education? The ASME Vision 2030 [2] suggests that Mechanical Engineeringcurricula must encourage and provide opportunities for active discovery-based learning in orderto meet the demands of the profession into the future.Each successive generation is more comfortable with technology than
