In thismodule we used numerical integration computer software to simulate our model. Throughmathematical modeling students were able to better define exposure limits within a BLSS withdifferent types of radiation shielding and countermeasures. Results from the model show the rateat which DNA damage occurs with and without shielding. Our model BLSS also integrates theenergy flow components occupying the system including human and plant life. In conclusion,through this module, students were able to design an
attempts to remedy this by leveraging computer animations to explicitly show students Page 22.935.2how statics is tied to everyday life and everyday situations they may encounter. One of theadvantages of computer animations is that they provide an important opportunity for students tomanipulate objects and tools – something that is often lacking, especially for women and URMswho are typically not taught or encouraged to take apart machines as they grow up. Anotheradvantage of computer animations is that they effectively scaffold students' efforts at modelbuilding and connect abstract problems with multiple real world applications – for example
literacyand interest in engineering.Year 1 – Computer engineering? -- More Like Multimedia Design Determined that engineering and technology would be valuable to an elementarycurriculum, in 2003 I set out to find a school that I could partner with. I was turned down by twoschools before I found a Principal that was interested. As the Principal of Canyon CrestElementary School and I began to discuss what it was I wanted, I naturally turned to definingtechnology and engineering. He listened politely, but suggested that their new iMac computerlab would be a great place to focus. Before accepting the role of teaching computers andinformation technologies, I made one more plug to teach other technical systems likemanufacturing, transportation
Recycling Gemstone RecyclingThe most of the devices, such as TVs, cellular phones, computers, laptops and music playerscurrently end up in landfills. In addition to valuable metals, such as aluminum, cupper, gold,silver, platinum and stainless steel, these devices often contain hazardous toxic materials (e.g.,mercury, lead, cadmium, arsenic, etc.). The toxic materials can contaminate air, soil and watereven at smaller quantities and can cause severe environmental and health problems. Table 2gives some of the toxic materials often used in electric, electronic, communication, printing andcopying and computer devices or their manufacturing [1-3,16].Table 2: Some of the harmful materials and their applications in

Virtual and simulator-basedlaboratories and experimentation can serve a valuable role in developing practical skills andbuilding familiarity with operating procedures, in a cost-effective manner that supports distance-learning. Leading educational institutions have appreciated the potential of remotely accessiblereal-world laboratory experiments well before the COVID-19 pandemic [5,6]. In this study, we will present two of the ongoing pedagogical developments for ourengineering students regarding virtual materials science laboratories: i) Virtual Reality apps andii) Scientific Emulators.

For example, a recent article by Miner and Link4, outlines theuse of SDRC I-DEAS5 software to perform static finite element analysis as part of thedesign process for a bracket in a Computer Aided Design course at the U.S. NavalAcademy. I-DEAS is one example of a commercial code capable of performing finiteelement analysis. Such codes, which have become much more sophisticated and user-friendly over recent years, can now be used effectively to illustrate concepts encounteredin
Society for Engineering Education• A young faculty member came into the FIC, sat down and sighed. “I lecture too much and I know the students can do more.” This faculty member was experiencing what educational research is suggesting - students need to be active in their learning. She needed student-centered strategies and techniques to introduce into her repertoire. She also needed a sounding board, someone to listen when she made changes that didn’t always register instant success. Together, we wrote a proposal to the Hewlett-Packard Corporation and received a grant for 60 handheld computer devices. The handhelds enabled the professor to solicit real-time student feedback. With more information on what students knew
growth of learning tools distributed through the internet has led to a dramatic increasein the number of freely available instructional tools applicable to both formal and informal learningsystems. These include experimental module demonstrations, comics, and educational videos. Ofparticular note are the videos produced by Crash Course, which have created 38 series of YouTubevideos, each focusing on individual subjects such as chemistry, history, or theater. The videosutilize animation to help highlight applications and theory, and have accumulated over 1.10 billionviews since the first series was launched. Crash Course: Engineering was a video series developed by Crash Course in associationwith PBS Digital, covering all fields of

The project team designed the following two research Page 26.99.5questions: What metacognitive knowledge do students use in solving engineering dynamicsproblems with a computer simulation and animation module? How do computer simulation andanimation modules affect the metacognitive knowledge and skills of students in solvingengineering dynamics problems? The REU students applied qualitative research methodology toanswer these research questions.Project 3 aims to identify student-oriented
the museum’s snake, “Jake.” Charlotte had a similar idea:"One idea is to pair it [the snake jaw robot] with a live feeding of one of our snakes. That is anice, easy one to do.” Marissa echoed this idea, “So I was thinking we could add that to when wedo our live animal presentation as part of that. If we use a snake we can the snake jaw there tokind of talk about how they work together.” The staff tried the live snake demonstration, whichwas met with a lot of enthusiasm from guests (see Figure 3). Ultimately, having a live snake andthe snake jaw robot at the same presentation could expand guests’ understanding of how snakeseat, their anatomy, and other topics. Figure 3.

software simulations of physical entities, suchas electronic circuits, denies the user a chance to physically handle the circuit components orconstruct the circuit.3 On the other hand, simulation has another major advantage in that asimulation is task- and learner-neutral; it models an object/system construction and operation orlearning situation. Within simulation functionality, there are no restrictions on the student’sactions. Thus, the advantages of simulation outnumber its disadvantages. In the areas ofelectrical and electronics engineering and technology and manufacturing technology, there arenumerous uses for simulation, starting from simulation of electric circuits to complex tasks suchas electromagnetic fields, networking, computer
programmable logic controller (PLC) related topics such as instructions, analog I/O,PID control, PLC languages, and factory communication3. However, these courses focusprimarily on PLCs. Pena et al. describe a new undergraduate degree program in controlengineering at the Federal University of Minas Gerais, Belo Horizonte, Brazil4. This program isoriented toward meeting industry needs and includes some automation courses, but has a heavyemphasis on control theory.There have also been many attempts to teach enabling skills that underlie system integrationskills, such as web sites or computer-based instruction that present introductory informationabout programmable logic controllers. One notable example is The Learning Pit’s LogixPro,which employs

Previous research1,2 has shown that students who learned fromteachings supplemented by animations performed better than those who learned through the text-only technique. Using graphics, simulations, animations of concepts and their applications hasthe potential to explain concepts more clearly and in a shorter time when compared to theconventional lecture-only approach. On the other hand, scientific computing allows the analysisof large, complex engineering problems, involving, for example the solution of coupled non- Proceedings of the 2013 ASEE Gulf-Southwest Annual Conference, The University of Texas at Arlington, March 21 – 23, 2013

Morphew1, & Michele McColgan2 1 School of Engineering Education, Purdue University, West Lafayette, IN 2 Department of Physics, Siena College, Loudonville, NYAbstractStudents struggle with developing conceptual understanding of abstract concepts in Science,Technology, Engineering, and Mathematics (STEM) courses. Two-dimensional (2D) figures arecommonly used during instruction in textbooks and multi-media presentations such as PowerPoint,or in computer animation. The use of 2D visualizations during instructions lacks opportunities forstudents to meaningfully explore these concepts by rotating three

Huang and Gramoll7 described the development, implementation, and functionality ofan interactive multimedia online eBook designed to enhance the learning experience of studentsin studying basic concepts of engineering thermodynamics. The eBook was comprised of 42case problems and each case covered a specific concept in engineering thermodynamics. Thestudents could learn from each case the required concepts, procedures to solve the case problem,and variation of the problem through simulation. Graphics, diagrams, animations, sounds, andhypertext were used to exhibit
often avoid creativesolutions that might prove embarrassing in a public load test. Designs rarely result from asystematic process. Students derive structural concepts from photos or from vague notions ofwhat bridges ought to look like. Designs, if they are developed at all, are seldom informed bymath or science. Even the design criterion—maximum strength-to-weight ratio—is unrealistic.Actual bridges are designed to carry code-specified loads safely, at minimum cost. Actualbridges are never designed to maximize strength-to-weight ratio.These inadequacies led us to use computer simulation in lieu of a physical model-buildingproject. This decision is consistent with the work of Harmon and Chung, who havedemonstrated that simulation can be used to

and interesting teaching methods are being developed andimplemented almost monthly due to the versatility of the Internet. In particular, the Internetallows convenient collaboration between students [1] for both engineering education and design[2]. Computers and electronic media can also be used to supplement traditional methods ofinstruction, such as lectures and textbooks, with simulations, animations and even on-demandvideo [3]. It would be hard to say that these new media types and networks are not useful in Page 7.1308.1teaching engineering education or for technical training. However, to use the Internet or Proceedings of the

The new course incorporated the computer programming courseand a separate engineering graphics course. The latter was previously taken at the sophomore orjunior level and had not yet utilized computer aided engineering tools. The new course was to bemuch more than simply a training venue for programming and graphics, however, as this paperwill show.The new two-course Engineering Principles sequence is structured around two broad goals: 1. To expose the freshman engineering student to the work of engineering through hands- on activities and projects in engineering problem

These courses, BioS286:Biology of the Brain and BioS 484:Neuroscience I provide much of the core contentessential for understanding and working with the nervous system. The core of the neuralengineering track consists of three neural engineering courses taught by BioE faculty(Fig. 1). BioE 472:Models of the Nervous System is a quantitative neurobiology coursefocusing on fairly classical topics in the domains of membrane physiology, signaling inexcitable cells, and synaptic communication. BioE:475:Neural Engineering 1 (NE1) is aseminar style course where students explore current issues in neural engineering by

From this a follower aircraft, which isrepresented by the derived nonlinear aircraft model, tries to stay with the Virtual Leader on itsflight path. This simulation environment also allows for the control system to autonomouslyinject maneuvers on the control surfaces during the simulation, similar to those performed inactual flight. This simulation also has a three-dimensional visualization environment, (using theSimulink 3D Animation® tool), which visually represents the YF-22 aircraft behavior.

For over a decade, computing educationhas evolved from textbooks to ebooks to interactive learning experiences with animations,built-in IDEs, and autograders. More recent work has shown that many of these innovations suchas paired programming, code visualizers, and Parsons problems have positive educationaloutcomes such as student engagement, retention, and increased learning gains
institutions lack the full range of resources needed tohelp students to become proficient with PLC programming. In addition, high faculty-studentratios and limitations in availability of equipment and lab time make it difficult for students tospend enough time with the equipment to become proficient.This paper will describe activities and findings related to an ongoing NSF-funded project todesign, develop, and evaluate Virtual PLC, a system that integrates multiple instructionaltechnologies and techniques into a single Web-based learning system that is comprehensive in itstreatment of PLC topics, motivational, and always available. Virtual PLC includes animations,interactive case studies, a ladder logic toolkit, and intelligent tutoring systems. In
advantage of thecontinuum limit of a chain of masses connected by springs is that it is easily comprehensiblefor students and, in addition, many materials respond to small perturbations just as if theywere a system of coupled oscillators. This harmonic oscillator response to perturbations leadsin a continuum model to the appearance of wave phenomena.For the visualization of such wave phenomena, a computer program that simulates a two-dimensional spring-mass system has been developed within an undergraduate student project.The model consists of a rectangular lattice of regularly spaced point masses connected to eachother and to the rigid boundary by a network of massless springs. The force on each mass iscomputed due to its spring connections with

All students workedon a variety of projects using a variety of materials (computational, mechanical, and crafts), simultaneously. Manywere purely computer-based, such as creating animations, making games, building simulations, managing stockportfolios, etc. Many projects were based upon Lego robotics.
