  • Most students who take EDD have some experience with other PLTW courses. In those previous PLTW courses, you learned about engineering design and gained many skills that you will apply in EDD.[Click through course hierarchy.][click] What can you do with the skills you learn in your PLTW courses? [Ask students what skills they have learned in prior PLTW courses and how those skills might help them in the future.] [click]
  • EDD is about finding and solving a real problem. In order to solve the problem, however, you have to constantly keep in mind the specifics of the problem so that you don’t deviate from your purpose. [click] This is a sign displayed during EDD project presentations at South Colonie Central School.
  • EDD follows one version of the design process. Many different version of the design process are available and used by professionals. PLTW uses the ITEA model from Standards for Technological Literacy.EDD is unique in the PLTW curriculum because in EDDyou have nearlythe entire course to work through the design process for a single design.
  • Notice the alignment of the course to the design process.
  • [Students should preview the flow chart so that they can reference the information and ask for clarification where necessary.]
  • By thoroughlyanswering the Ten Mighty Questions, you will progress successfully through the design process.[Students should preview the 10 Mighty Questions so that they can reference the information and ask for clarification where necessary.]
  • This flow chart follows the Ten Mighty Questions and is a more specific representation of the process you will follow as you complete your EDD project.
  • The rule of thirds breaks up the design problem into three distinct parts each of which represents approximately one-third of the effort that should be expended on the project. Note that the first third involves finding and specifically describing the problem that you will solve in a proposal. Although many students want to jump into creating a solution, it is very important that you make sure that you have a real, valid problem that has not yet been adequately solved. You also need to make sure that it is worth the effort to solve the problem and describe the problem in very specific language. All of this takes time, but is well worth the effort because it provides a basis on which to build the solution and justifies the effort that you will expend toward finding the solution.
  • Act like a professionalYou will be working closely with a team. Act professionally at all times. When you agree to do something, do it on time and do it well. Play nice.Know your topicLearn as much as you can.Seek and ask for help.You will need to seek more expertise than your instructor can provide. Look for experts and do research to be sure that you have sufficient and accurate information as you work toward solving a problem.Project ScheduleAttempt to adhere to your project schedule in order to successfully complete all phases of the design process.Continuously adjust your project schedule to reflect your work progress and appropriately allocate the time remaining.OrganizationThis course will teach you a lot about project management. You will acquire many skills that will benefit you for the rest of your life. Most students who experience stress in EDD discover the root of the problem is a lack of organization. When your team is organized, everyone is more likely to be prepared for bumps in the road. Being organized means that you have a plan and you always know the next step in the process. For this course you will need to have a few tools to stay organized. Engineering Notebook – This is used to capture original ideas, reflections, modifications, etc., basically anything related to the design thought process.3-Ring Binder – Your binder should collect all of your class work, notes, and other related material. Be sure this stays organized so you will be able to access what you need.DocumentationKeep accurate records of everything you do and create – both written and with pictures. Keep records of your thoughts, self-assessments, research, conversations, correspondence, sketches, timelines, etc. Anything that has anything to do with your project should be documented.
  • Make an effort to approach the problem with an open mind – don’t have a solution in mind before you have really investigated the problem.[click] Although many EDD projects result in physical devices, some problems are better solved with a new method or process. Let your research (not your preference) drive the solution path that you take.For example, after you research a problem and the existing solutions, you may find that performing certain actions in a specific order solves the problem; so your solution would be the process or steps that describe those actions in the correct order. Or maybe altering an existing manufacturing process or changing an assembly order solves the problem. Or, perhaps treatment with a specific chemical substance is the best solution.
  • Consider all possible solution paths. Some problems are better solved by modifying or combining existing solutions.
  • Good documentation throughout your design process is crucial to your success in EDD. It provides… [click through list}In particular, you will keep an engineering notebook [click] to chronologically document all of the work on your project. You will also create a project portfolio [click] (hardcopy or digital) to highlight the outcome of your work.
  • Clint Downey and Jackson Cover of Cedar Rapids Jefferson High School [click] have filed for a provisional patent on their new design for a marching band lyre. A lyre attaches to an instrument such as a trumpet or clarinet to hold sheet music in place so that it can be viewed while playing the instrument.[click] While taking EDD, Clint and Jackson were encouraged by the inventor and patent holder of the current lyre design.[click] They interviewed many musicians and band directors to identify problems with the existing lyre design. As a result, Clint and Jackson created a design that solves many of these problems.[click] Both Clint and Jackson went into engineering at the University of Iowa, and both are in the Hawkeye Marching Band!You can read more about Clint and Jackson’s invention in the IA EDD Music Lyre Patent Article.
  • Chantel Newman of St. Thomas More High School in Milwaukee worked with patients and health care workers to identify a unique problem that lead to her to design an improved crutch.She presented the design at the Capitol [click] Chantel received the highest award for the engineering division in the Badger Science Fair and[click] a $40,000 scholarship in engineering to Marquette University.[click]
  • Adam Martin from East High School in Wausau, WI designed a [click] training ski for cross country skiers that could be used during the non-snow season. [click]
  • Adam is a cross country ski racer and designed the device to help him train. His design requires him to shift his bodyweight in a way that better mimics the motion of a cross country skier than other existing designs.Adam consulted with the Small Business Development Center at the University of Wisconsin called the Wisconsin Innovation Service Center – Whitewater (WISC). [click] WISC specializes in research to help innovators in the early stages of design decide whether or not to proceed with the design effort. [click]
  • The InvenTeam from Tesla Engineering Charter School in Appleton, WI received a grant from the Lemelson-MIT Program to invent an energy saving refrigeration process for northern climates. [click] The EDD team worked together on a solution and presented their invention at EurekaFest 2009 at MIT. [click][click]
  • Many experts from post secondary institutions as well as well know companies share their thoughts on EDD. [Click on one of the two names at the top to play a video. To view other interviews about the EDD course please download them from the PLTW Virtual Academy.]
  • This flowchart provides an overview of the process that you will follow during EDD.In the process of selecting and solving your problem, you will complete multiple tasks including[click through list]Notice the arrows that indicate that some steps may need to be repeated. There may be times when you need to adjust or revise your problem or solution path and need to repeat previous steps.
  • In EDD you will use the engineering design process to find a solution to a valid problem.
  • Finally, you will present your work to an outside panel
  • You may wish to take your design project a step further after you complete EDD. Within the curriculum you will find a section titled “Going Beyond” in which you will find valuable information to help you find design competitions, scholarship opportunities, internship opportunities, college recognition and intellectual property resources.
