The Engineering Design Process Is it the same as the “Scientific Method”?
What is the “Scientific Method”? • Organized thought process to solve problems and answer questions---NEW INFORMATION • Steps: • Recognize problem or question • (literature search) • Observe some phenomenon • Hypothesize • Experiment • Collect data (REPEAT) • Analyze data • Report
What are some of the conditions for the scientific method? • Only one hypothesis can be true. • Hypotheses can only be disproven • Theory predicts behavior • Open to change and reevaluation
The Engineering Design Method • Define the Problem • Research past work in this area • Brainstorm possible solutions • Choose a “best solution” • Analyze this solution • Modify the solution • Iterate!!!!
Scientific Method ANSWER QUESTION EMPLOY PEOPLE EXPLAINS NATURAL PHEN. REPORT RESULTS OF AN RELY ON QUAN. ANAL. RELY ON QUAL. DATA NEVER REALLY DONE FOR KNOWLEDGE EXPAND WHAT WE KNOW Engineering Design SOLVE PROBLEMS EMPLOY PEOPLE CREATE AN END PRODUCT REPORT RESULTS OF AN. FOR PROFIT RELY ON QUANT. ANALYSIS MORE RELY ON QUAL. AN. FINAL PRODUCT COMPLETES PROCESS USE SCIENTIFIC PRINC. HIGHER PAY IN GENERAL So let’s compare the two:
Engineering Design: • Multiple solutions • Best solution based on • Economics • Social Implications • Aesthetics • Client preference • Technical constraints • Non-technical constraints • Safety • Resources • Environment
Can Engineering Design fit into Inquiry Based Science Education? • IDENTIFY PROBLEM • GET STUDENTS TO WANT TO FIND ANSWER
The engineering design method as a problem solving technique
Math problem solving • Understand Problem • Read carefully several times • Restate problem in own words • Identify important information • Nine strategies • pattern • organized list • simpler problem • Table • Act it out (MODEL) • Logical reasoning • Work backwards • Guess and check • Picture or diagram • Carry out strategy • Review (REASONABLE SOLUTION)
