Demonstrate the ability to verify the correctness of a program.

Unpacked Content

Knowledge

Students know:

proper syntax and formatting for a coding language.
how to identify coding errors in a programming language.

a.

programs must be tested to verify that the desired task is executed properly.
testing a program requires a scenario where you can easily verify that the result of the program is correct/accurate.

b.

a program can contain one of the following properties, but not be an appropriate program: correctness, efficiency, scalability and readability
it is important to have others review your code.
that to be a quality program, code must be correct, efficient, scalable and readable.

Skills

Students are able to:

analyze code for proper syntax and formatting.

a.

create a test case with verifiable results.
execute a program with the created test case to verify program performance.
locate errors in programming by executing test cases.

b.

work with others to review their code for correctness, efficiency, scalability and readability.

Understanding

Students understand that:

programming languages each have their own required formatting which must be adhered to for a program to run correctly.
errors in programming languages prevent the program from executing its task.
each language has its own syntax and method for identifying potential errors.

a.

code can be formatted correctly and a program can still produce unintended results.
a test case is vital to verifying that a program is executing a task as intended.

b.

to be a quality program, code must be correct, efficient, scalable and readable.
it is important to have others proofread your code.
