Types of Validation
There are different types of validation such as data validation, form validation, and input validation.

Slide 12 - Slide

Explain the different types of validation and give examples of each.
Data Validation
Data validation is the process of checking whether the data is correct and meets the expected format and requirements.

Slide 13 - Slide

Explain the concept of data validation and give examples of how it can be implemented.
Form Validation
Form validation is the process of checking whether the form data is correct and meets the expected format and requirements.

Slide 14 - Slide

Explain the concept of form validation and give examples of how it can be implemented.
Input Validation
Input validation is the process of checking whether the input data is correct and meets the expected format and requirements.

Slide 15 - Slide

Explain the concept of input validation and give examples of how it can be implemented.
Input Validation Techniques
There are different techniques for input validation such as length validation, range validation, and type validation.

Slide 16 - Slide

Explain the different techniques for input validation and give examples of each.
Length Validation
Length validation is the process of checking whether the input data has the expected length.

Slide 17 - Slide

Explain the concept of length validation and give examples of how it can be implemented.
Range Validation
Range validation is the process of checking whether the input data is in the expected range.

Slide 18 - Slide

Explain the concept of range validation and give examples of how it can be implemented.
Type Validation
Type validation is the process of checking whether the input data has the expected type.

Slide 19 - Slide

Explain the concept of type validation and give examples of how it can be implemented.
Error Handling
Error handling is the process of dealing with errors and exceptional situations in the program.

Slide 20 - Slide

Explain the concept of error handling and give examples of how it can be implemented.
Exception Handling
Exception handling is the process of dealing with unexpected errors and exceptional situations in the program.

Slide 21 - Slide

Explain the concept of exception handling and give examples of how it can be implemented.
Try-Catch Block
The try-catch block is a programming construct for handling exceptions and errors in the program.

Slide 22 - Slide

Explain the concept of try-catch block and give examples of how it can be implemented.
Debugging
Debugging is the process of finding and fixing errors and bugs in the program.

Slide 23 - Slide

Explain the concept of debugging and give examples of how it can be implemented.
Debugging Techniques
There are different techniques for debugging such as print statements, breakpoints, and logging.

Slide 24 - Slide

Explain the different techniques for debugging and give examples of each.
Print Statements
Print statements are statements that print the value of a variable or an expression to the console for debugging purposes.

Slide 25 - Slide

Explain the concept of print statements and give examples of how it can be implemented.
Breakpoints
Breakpoints are markers in the code that pause the program execution for debugging purposes.

Slide 26 - Slide

Explain the concept of breakpoints and give examples of how it can be implemented.
Logging
Logging is the process of writing messages to a log file for debugging and analysis purposes.

Slide 27 - Slide

Explain the concept of logging and give examples of how it can be implemented.
Write down 3 things you learned in this lesson.

Slide 28 - Open question

Have students enter three things they learned in this lesson. With this they can indicate their own learning efficiency of this lesson.
Write down 2 things you want to know more about.

Slide 29 - Open question

Here, students enter two things they would like to know more about. This not only increases involvement, but also gives them more ownership.
Ask 1 question about something you haven't quite understood yet.

Slide 30 - Open question

The students indicate here (in question form) with which part of the material they still have difficulty. For the teacher, this not only provides insight into the extent to which the students understand/master the material, but also a good starting point for the next lesson.
