How can students analyze data to improve a design solution?

• Memorize the data

• Compare similarities and differences among solutions

• Ignore the data

• Focus only on the cost

Answer explanation

Students can analyze data by comparing similarities and differences among solutions, which helps identify strengths and weaknesses, leading to improved design solutions. Memorizing or ignoring data is not effective.

Why is it important to use a systematic process when evaluating design solutions?

• To ensure the process is quick

• To ensure all criteria and constraints are considered

• To focus only on the most expensive solution

• To avoid using scientific principles

Answer explanation

Using a systematic process ensures that all criteria and constraints are thoroughly evaluated, leading to well-informed design solutions. This approach helps avoid overlooking important factors that could impact the effectiveness of the design.

How can students plan to solve a design problem?

• By ignoring constraints

• By using evidence and reasoning

• By focusing only on aesthetics

• By avoiding scientific principles

Answer explanation

Students can effectively solve design problems by using evidence and reasoning, as this approach allows them to analyze constraints and make informed decisions, rather than ignoring important factors or focusing solely on aesthetics.
