Brainstorming Solutions
STEMCenter for Teaching & Learning™ Engineering byDesign™ 12/01/2009 Brainstorming Solutions When working as a group, record your ideas and employ the rules of brainstorming: One conversation at a time; stay focused. Encourage wild ideas, quantity vs. quality. Defer judgment and build on the ideas of others. Use Mind Mapping, the da Vinci Method, or Inventive Problem Solving as appropriate. [Authors: Please include teacher notes appropriately.] © 2013 International Technology and Engineering Educators Association, STEMCenter for Teaching and Learning™ Foundations of Technology © International Technology Education Assoc
17
Research Ideas/ Explore Possibilities
STEMCenter for Teaching & Learning™ Engineering byDesign™ 12/01/2009 Research Ideas/ Explore Possibilities Research is essential in determining the best possible solution. Identify how the problem or a similar problem was addressed in the past. Determine what mathematical and/or scientific background knowledge is essential to solve the problem. [Authors: Please include teacher notes appropriately.] © 2013 International Technology and Engineering Educators Association, STEMCenter for Teaching and Learning™ Foundations of Technology © International Technology Education Assoc
18
Specify Constraints and Identify Criteria
STEMCenter for Teaching & Learning™ Engineering byDesign™ 12/01/2009 Specify Constraints and Identify Criteria Good design follows a set of given or identified criteria and constraints: Criteria = Guidelines Constraints = Limitations Document the essential criteria and constraints needed to solve the problem. The application of criteria and constraints is done throughout the Engineering Design Process. Balancing criteria and constraints may result in a trade-off or an exchange of one thing in return for another. [Authors: Please include teacher notes appropriately.] © 2013 International Technology and Engineering Educators Association, STEMCenter for Teaching and Learning™ Foundations of Technology © International Technology Education Assoc
19
Specifying the Criteria
STEMCenter for Teaching & Learning™ Engineering byDesign™ 12/01/2009 Specifying the Criteria Criteria are the goal(s) that must be met in order to successfully solve the problem. They include the elements and/or features of a product or system and how the design should function. [Authors: Please include teacher notes appropriately.] © 2013 International Technology and Engineering Educators Association STEMCenter for Teaching and Learning™ Foundations of Technology © International Technology Education Assoc
20
Identifying the Constraints
STEMCenter for Teaching & Learning™ Engineering byDesign™ 12/01/2009 Identifying the Constraints Constraints are factors that limit the design or limit how the problem can be solved. Common constraints almost always involve safety, time, budget, materials, etc… [Authors: Please include teacher notes appropriately.] © 2013 International Technology and Engineering Educators Association STEMCenter for Teaching and Learning™ Foundations of Technology © International Technology Education Assoc
21
Consider Alternative Solutions
STEMCenter for Teaching & Learning™ Engineering byDesign™ 12/01/2009 Consider Alternative Solutions Always consider alternative solutions and DO NOT allow preconceptions to limit your ideas. It is important to stay open-minded. Compare each of your design ideas with the criteria and constraints to determine how well they solve the problem.

Develop a Written Design Proposal
STEMCenter for Teaching & Learning™ Engineering byDesign™ 12/01/2009 Develop a Written Design Proposal Once an idea has been selected, it is important to develop a plan of action. A Design Proposal is a way to manage simple projects, which includes: The who, what, when, where, and how to deliver the work. Often includes descriptions, sketches, and technical drawings. Begin to plan how the solution will be evaluated.

Develop a Written Design Proposal
STEMCenter for Teaching & Learning™ Engineering byDesign™ 12/01/2009 Develop a Written Design Proposal When developing a design proposal, you will need to plan ahead to determine how you will evaluate your design. What tests will be conducted to determine if criteria are being met? What data will be collected? How will those data be used to improve the solution? [Authors: Please include teacher notes appropriately.] © 2013 International Technology and Engineering Educators Association, STEMCenter for Teaching and Learning™ Foundations of Technology © International Technology Education Assoc
