Topic: Design test and refinement 

Engineering Education

 Standard 14.  Uses the design process to solve problems
  Level IV (Grade 9-12)
   Benchmark 6.Uses optimization techniques, such as linear programming, to determine optimum solutions to problems
    Knowledge/skill statements
     1.Uses linear programming to determine optimum solutions to problems

Technology

 Standard 4.  Understands the nature of technological design
  Level II (Grade 3-5)
   Benchmark 7.Evaluates a product or design (e.g., considers how well the product or design met the challenge to solve a problem; considers the ability of the product or design to meet constraints), and makes modifications based on results
    Knowledge/skill statements
     1.Knows that the evaluation of a product or design often leads to modifications of the product or design
     2.When evaluating a product or design, considers how well the product or design met the challenge to solve a problem
     3.When evaluating a product or design, considers the ability of the product or design to meet constraints
     4.Modifies products or designs based on evaluation results
  Level III (Grade 6-8)
   Benchmark 6.Evaluates the ability of a technological design to meet criteria established in the original purpose (e.g., considers factors that might affect acceptability and suitability for intended users or beneficiaries; develop measures of quality with respect to these factors), suggests improvements, and tries proposed modifications
    Knowledge/skill statements
     1.Evaluates the ability of a technological design to meet criteria established in the original purpose
     2.Considers factors that might affect acceptability and suitability for intended users or beneficiaries when evaluating a technological design
     3.Develops measures of quality with respect to acceptability and suitability when evaluating a technological design
     4.Suggests improvements following the evaluation of a technological design
     5.Tries proposed modifications following the evaluation of a technological design
  Level IV (Grade 9-12)
   Benchmark 2.Proposes designs and uses models, simulations, and other tests to choose an optimal solution
    Knowledge/skill statements
     1.Proposes a design, using models to choose an optimal solution
     2.Proposes a design, using simulations to choose an optimal solution
   Benchmark 4.Evaluates a designed solution and its consequences based on the needs or criteria the solution was designed to meet
    Knowledge/skill statements
     1.Evaluates a designed solution based on the needs or criteria the solution was designed to meet
     2.Evaluates the consequences of a designed solution based on the needs or criteria the solution was designed to meet
   Benchmark 5.Knows that since there is no such thing as a perfect design, trade-offs of one criterion for another must occur to find an optimized solution
    Knowledge/skill statements
     2.Understands that trade-offs of one criterion for another must occur to find an optimized solution
