Lesson 27- If Statements

Summary: IF statements allow your program to do different things dependent on boolean conditions. The body of the IF statement is either executed or not, which affects the flow of the program.

Learning Objectives:

• Define an If Statement
• Evaluate a conditional expression
• Determine whether a situation requires an If statement
• Write code that involves simple if statement
• Write code that involves nested if statements
• Write code with branching conditions
• Trace branching control flow
• Differentiate between double IFs and the ELIF

Activities:

• Lesson: If Statements
• Quiz: If Statements
• Programming: If Statements

Misconceptions:

• Students believe that IF statements are required to write boolean expressions
• Students do not understand how expressions can be evaluated in a Truthy way
• Students believe that it is necessary to test booleans for equality with True and False (is_raining==True)

Lesson 28- Truthiness

Summary: Any expression can be used as a conditional expression. Succinctly, any zero or empty value is considered false, and non-zero/non-empty values are considered true.

Learning Objectives:

• Define the concept of Truthiness
• Evaluate a conditional expression

Activities:

• Lesson: Truthiness
• Quiz: Truthiness

Misconceptions:

• Students do not understand how expressions can be evaluated in a Truthy way
• Students believe that it is necessary to test booleans for equality with True and False (is_raining==True)

Lesson 29- Nested Ifs

Summary: IF statements allow your program to do different things dependent on boolean conditions. The body of the IF statement is either executed or not, which affects the flow of the program.

Learning Objectives:

• Write code that involves nested if statements
• Write code with branching conditions
• Trace branching control flow
• Differentiate between double IFs and the ELIF

Activities:

• Lesson: Nesting Blocks
• Quiz: Nesting Blocks
• Programming: Nesting Blocks

Misconceptions:

• Students do not understand that IF statements are sometimes unnecessary

Lesson 30- Lists

Summary: Lists are a complex type that hold multiple values at once.

Learning Objectives:

• Define the term “Composite Type”
• Create a list literal
• Identify the subtype of a list
• Differentiate between lists and empty lists

Activities:

• Lesson: Lists
• Quiz: Lists
• Programming: Lists

Misconceptions: None listed so far

Lesson 31- List Operations

Summary: You can use several different operations on a list, and lists have methods so they can be manipulated.

Learning Objectives:

• Subscript an element from a list
• Subscript a slice within a list
• Explain the nature of zero-based indexing
• Append an element to a list
• Pop an element from a list
• Create a list using range()

Activities:

• Lesson: List Operations
• Quiz: List Operations
• Programming: List Operations

Misconceptions: None listed so far
