The value of doing projects as a vehicle for instruction has been integral to technology and engineering classes for decades. With the increased emphasis on STEM, project-based learning is becoming more popular with all teachers. Realistically, classrooms can be limited, however, in the tools, materials, and processes needed for project-based…

One effort to reducing air pollution and global warming in recent years has centered on the replacement of fossil-fuel-burning vehicles with alternative energy options such as electric-powered transportation. In fact, electric vehicle technology is one of the fastest-growing, and ever-evolving, sectors of the energy industry (TR Fastenings, 2019).…

The International Technology and Engineering Educators Association (ITEEA's) Science Technology Engineering and Math (STEM) Center for Teaching and Learning's Engineering by Design™ (EbD™) is a standards based Integrative STEM Education model program that provides curriculum, professional development, and assessments to K-12 schools. This article…

Within the past few years there has been an increasing emphasis on making computer science (CS) more accessible for all K-12 students. In 2013 there were 12 states that allowed CS courses to count towards high school graduation, and in 2018 that number had grown to 35 states plus the District of Columbia (Code.org, 2018). Due to the increasing…

Technology, engineering, and design (TED) education is replete with hands-on projects and activities to engage students in project- and problem-based learning. TED design briefs provide a realistic context for problems so that students are immersed in as realistic a problem scenario as possible. This article provides a model of best practice for…

A serious drawback to electric vehicles [batteries only] is the idle time needed to recharge their batteries. In this challenge, students can develop ideas and concepts for battery change-out at automotive service stations. Such a capability would extend the range of electric vehicles.

Students graduating from today's campuses are entering a world where alternative energy vehicles are becoming more reality than concept. Students at all levels of education must be prepared for this reality, whether entering college, graduate study, industry, or simply functioning as a consumer. At the Technology and Industrial Arts Department at…

Traffic lights are an important part of the transportation infrastructure, regulating traffic flow and maintaining safety when crossing busy streets. When they go awry or become nonfunctional, a great deal of havoc and danger can be present. During power outages, the street lights go out all over the affected area. It would be good to be able to…

Roadways are literally soaked with petrochemical byproducts, oils, gasoline, and other volatile substances that eventually run off into sewers and end up in rivers, waterways, and other undesirable places. Can the roads be cleaned of these wastes, with their proper disposal? Can vehicles, robots, or other devices be designed that could be driven…

Over 100 years ago, the great inventor Thomas Edison warned that gasoline cars would pollute the environment and lead to gasoline shortages. He preferred the use of clean electric vehicles. He also put his money where his mouth was and developed an entirely new alkaline storage battery system for his beloved cars, the nickel-iron storage battery.…

Street intersections are a source of accidents--for both automobiles and pedestrians. This article presents an intersection challenge that allows students to explore some possible ways to change the traditional intersection. In this challenge, teachers open up the boundaries and allow students to redesign their world. The first step is to help…
