theconcrete cross-section or steel rebar (referred to herein as “3-D stress block”). Part of thedifficulty that students face comes from the fact that most instruction on flexural analysisinvolves the 2-D strain-to-stress-to-force diagrams shown in Figure 1, and it is difficult tovisualize the associated 3-D stress blocks. Figure 1. 2-D Strain-to-Stress-to-Force Diagrams for Rectangular Beams subject to Flexure: (Top Left) Linear, (Bottom Left) Parabolic, and (Right) Equivalent Rectangular Stress StatesTo clarify this concept, a set of physical models for various stress conditions in rectangularbeams was created. Figure 2 shows the models associated with: a) concrete compressive stress at the extreme compression fiber (𝑓𝑐 ) is less than 0.5
engineers thatcan lead to cost reductions and expediting product development in extremely complexengineering environments. The present study, pioneered by a large US aerospace companyworking with educators at 5 major engineering schools in the US, engineering educationresearchers, and practicing engineers, is a first step towards achieving this overall vision. In thispaper, we characterize how engineering students enrolled in a senior capstone course interact andperform on complex engineering tasks commonly seen in the aerospace industry. We describeour instrumentation methodology and the data architecture for an associated analytics platform.We use course clickstreams, social networking and collaborations as the basis for ourobservations.1
kg of PLA were also purchased for testing.Now, the lab technicians could make filament for about $10 per kg. However, the extrusionmachine depicted in Figure 1 was relatively hard to use. While the extruder had a classic PID(Proportional Integral Derivative) temperature controller, the spool motor did not work asintended. It seems that its motor driver would quickly overheat and stop applying power to thespool motor. So, the spool mechanism was bypassed. The extrusion machine was placed near theend of a table and the filament was allowed to simply drop on the floor. This worked, but itrequired some extra effort to wind filament onto the spool. Also, some experimentation with theextrusion machine was required to achieve the optimal extrusion

The course introduces project-defining skills for use in asequence of engineering design courses taken later in the undergraduate program. Proposal-Based Learning is similar to Project-Based Learning, and is comprised of the followingelements: 1) requires a response to an open-ended challenge; 2) creates a need to understand

Thiswas in contrast to the survey results from Fluid Mechanics, a traditional engineering core course,with a highly analytic, mathematical approach. Exit surveys of students in Fluid Mechanic reveala negative shift in affect toward fluids, which is typical of other technical courses and theircontent areas.More specifically, the responses from Flow Vis students can be termed an “expansion ofperception” – when learners see everyday objects, events, or issues through the lens of thecontent2. Expansion of perception is often associated with deeper conceptual understanding andthe ability to transfer

Results from the first cohort of students to participate in both these courses andcompleted their first coop rotation is analyzed to understand the effects of the first-year courseson student preparation and performance, particularly related to professional skills and problemsolving abilities.IntroductionEngineering programs across the country have seen a significant decrease over the past severaldecades in the number of students both enrolling and persisting.1-2 This has led to a lack ofindividuals with the necessary qualifications to fulfill the demands of industry within the UnitedStates.3 A
approaches that have been practiced for 50 years are continued [1, 2]. It isnecessary to find an alternative teaching strategy in engineering courses, particularly forconveying scientific principles to real situations. To assess innovative methods for solving theproblems and limitations of the traditional teaching model in chemical engineering andbiomedical engineering, a half interactive hands-on learning experiment, half lecture-teachingmodel is being explored. In this process, having the aim of a better understanding and absorptionof key principles and difficult concepts in fluid mechanics and neuronal membrane physiology,we are combining multimedia technology with whiteboard and hands-on tabletop units.A Fluid Mechanics and Heat Transfer course

Active learning has been shown by many educational researchers to result in superiorlearning outcomes over traditional methods like lecturing.1-3 Experiments can provide a enrichedplatform for active learning provided they are not too ‘cooked’ or recipe driven so that studentscan explore and play.One possibility is to develop experiments that students can put together themselves at home.Several groups have

versusgraduate-entry medical students, Dugan et al.1 found that the graduate-entry students didsignificantly better in their senior dissertation assessment.A large number of students suffer from test anxiety that results in poor performance. In one of thevery early studies dealing with this phenomenon, Hembree5 analyzed the performances of 562students ranging from elementary to college levels. He found that test anxiety reduced theperformance of students at every level. However, the study indicated that undergraduates had ahigher level of test anxiety than the graduate students.There are a wide range of articles written about good practices of both undergraduate and graduateeducation.

When assessment fills this role, itis known as formative assessment [1]. High quality feedback provided through formativeassessment has long been known to be an essential part of the learning experience [1]–[3].Another role that assessment can also fill is to verify that at the end of an instructional unit, thestudent sufficiently understands the content.

Based on the outcome ofthese discussions, a 15-minute review lecture was prepared by the faculty to address the issuesthat were raised during the student groups’ discussions. Following this brief lecture, the classwas turned into a studio environment in which students were able to put into practice what theyhave learned inside and outside the classroom. Before the end of the lecture session, an onlinequiz was administered to monitor the students' level of preparation and understanding of thetopics being covered. It was shown that the proposed model had succeeded in 1

Nontraditional instructionalmethods such as learning-by-doing methods, active and collaborative learning techniques aregetting more popular in the past few years. This trend is mostly reflected by introducing variousphysical simulation or computer games (gamification) and is growing rapidly due to theirpositive impact on learning process [1, 2].
