PLTW DM/AR Final Exam Review

Students are working on a project, they have completed the following steps: research, brainstormed and chose the best idea, drew sketches to produce their solution. What is their next step of the design process?

• build and test solution

• present solution

• evaluate solution

• design a solution

Which of the following behaviors can negatively impact team success?

• Group members listen to everyone's ideas

• Group members feel free to disagree, but all comments are helpful

• Group members only focus on the ideas of those with the best grades.

• Group members understand their tasks and help each other.

Why is sketching an effective communication tool?

• Designers can color parts of a sketch to show texture and communicate an object’s appearance

• Sketching allows designers to accurately communicate details of their ideas with lots of information at once

• Using sketches to communicate ideas makes the design neat and pleasing to the eye

• Sketching tells a story about the design, such as how it might be used or where it will be made

Why might a designer or engineer use an isometric sketch rather than a perspective sketch to communicate their idea?

• An isometric sketch can be drawn using multiple vanishing points, depending on the complexity of the object

• An isometric sketch has more accurate design details, because it shows a view similar to what our eyes actually see

• An isometric sketch uses dimensions to communicate height, width, and depth, whereas dimensions cannot be used in perspective sketches

• An isometric sketch has no vanishing points and all horizontal and vertical lines are parallel to show details on three sides of an object simultaneously

Why is a decision matrix an important tool to use in the design process?

• A decision matrix is used to identify the criteria, constraints, and deliverables

• A decision matrix organizes your sketches, models, and brainstorming

• A decision matrix determines the best solution by comparing design ideas to the criteria and constraints

• A decision matrix is a contract between the client and the designer

Engineers, scientists, and designers innovate products by taking apart existing products and observing and documenting how they work, to determine how they can be improved. What is this process is called?

• statistical analysis

• mechanical dissection

• mathematical modeling

• Brainstorming

Which of the following is NOT common practice of computational thinking when solving complex problems?

• Decomposing problems and using algorithms

• Generating and applying mathematical models

• Measuring and dimensioning accurate sketches

• Modeling and simulating complex systems

While there are different versions of the design process, what are the essential elements in any type of design process?

• The design process is linear, and each step must be completed in order and cannot be repeated

• The design process must be iterative where designers can revisit previous steps to modify and change their design based on failures and testing

• The design process must include steps for brainstorming and developing a design solution, but does not need to include design testing

• The design process must include steps for brainstorming and developing a design solution, but does not need to include design testing

What is unique about a device or product that is universally designed?

• The object can be used by animals as well as humans in different types of environments

• The object can be used in different types of environments without breaking

• The object can be used in different types of environments without breaking

• The object is designed so that most people can use it without having special adaptations
