ETS1B - Developing Possible Solutions

Paul Anderson discusses the process of developing possible solutions, starting with defining a problem and understanding its criteria and constraints. He introduces The Candle Problem as an example of brainstorming solutions. The video covers evaluating solutions, creating models, and using computer-assisted design. It outlines a teaching progression from elementary to high school, emphasizing sketching, research, and prototyping. The video concludes with solving complex problems using a systems approach, highlighting the importance of models and simulations.

What is the main objective when brainstorming solutions to a problem like the Candle Problem?

• To find the quickest solution

• To come up with as many solutions as possible

• To use only the materials provided

• To solve the problem without any constraints

What is the purpose of considering constraints and criteria when evaluating solutions?

• To choose the solution that takes the least time to implement

• To find the most popular solution

• To ensure solutions meet the necessary requirements and desired outcomes

• To eliminate solutions that are too expensive

In the teaching progression, what is emphasized in the lower elementary grades?

• Using computer-assisted design

• Sketching possible solutions

• Conducting market research

• Building complex models

What is the iterative process in prototyping primarily focused on?

• Using only digital simulations

• Creating a single perfect model

• Testing and modifying designs repeatedly

• Building models without testing

How does the systems approach help in solving complex engineering problems?

• By breaking the problem into smaller, manageable parts

• By ignoring constraints

• By focusing on a single aspect of the problem

• By using only physical models

What role do models play in the systems engineering approach?

• They are used to predict outcomes without testing

• They help in visualizing and simulating different aspects of the solution

• They replace the need for real-world testing

• They are only used for aesthetic purposes

Why is it important to start prototyping as quickly as possible?

• To avoid using digital tools

• To quickly identify and address design flaws

• To reduce costs

• To finalize the design without changes
