Lesson 1 PRACTICE Assessment - PLTW (CSIM)

Which of the following diagrams shows how the parts of the computer interact with each other?

• 
• 
• 
• 

In the Microsoft MakeCode environment, what are the blocks of code contained in?

• Drawers

• Menus

• Tabs

• Folders

What does PLTW stand for?

• Project Lead the Way

• Programs Lead the Way

• Project LED's the Web

• Programs Lead the WiFi

Why is it important to code trace (debug programs)?

• To figure out the errors in the code and fix them

• To flowchart the program's logic

• It's not important to fix errors

• To change patterns in the code

When creating a program, how does the use of comments help a computer scientist debug later problems?

• Comments show where a bug is located in the code

• Comments are opinions form others about how well the code works

• Comments are to describe the code, logic, and desired outcome (tell the user what the program does).

• Comments highlight code that needs to be fixed

In the Microsoft MakeCode environment, which block of code lets the user run a program, or part of the program, a specific number of times? What is the drawer this block is located in?

• Repeat block; Loops drawer

• Repeat block; Input drawer

• Forever block; Basic drawer

• Repeat block; Basic drawer

In a flowchart, you begin with an oval shape, which means to begin or end, except when

• Your programming code begins with a forever block

• Your programming code has a decision to be made

• Your programming code begins when the user pushes buttons A or B

• Your programming code has a pause block

What is the flowcharting shape for a decision?

• Rectangle

• Oval

• Rhombus

• Arrow

What is the difference between a linear and conditional flowchart/algorithm?

• A linear algorithm has a decision.

• A conditional algorithm has a decision.

• Neither algorithm would have a decision.

• Both algorithms would have a decision.

In the Microsoft MakeCode environment, which drawer can you find a block to create an LED light pattern on your micro:bit grid?

• Variables

• Logic

• Input

• Basic
