The Software Development Life Cycle (SDLC) is the process used by professional programmers to build high-quality software. It involves several stages: planning, designing, coding, testing, and evaluating. This topic teaches students that coding is only one part of a much larger project.
Activity 01
Divide the class into 'departments' (Design, Coding, Testing). A 'client' (the teacher) gives a simple request. The project must pass through each department, with students experiencing how a lack of planning in 'Design' makes 'Coding' impossible.
What are the phases of software development?
Activity 02
Groups are given a 'user' (e.g., a grandmother who wants to video call her grandkids). They must design the interface of a simple app for her, focusing on her specific needs before they even think about the code.
Why is planning crucial before coding?
Activity 03
Students create paper prototypes of a simple game or app. They display them, and 'users' (other students) try to 'click' the paper buttons. The 'developers' take notes on where the users get confused.
How do user needs shape software design?
A few notes on teaching this unit
Watch Out for These Misconceptions
Coding is the most important and longest part of making software.
In reality, planning and testing often take much more time. Using a 'time-tracking' activity during a project helps students see that 'thinking' and 'fixing' are just as vital as 'typing'.
You only test the software once it is completely finished.
Testing should happen at every stage. A 'bug-hunt' activity on early prototypes helps students realize that finding errors early saves a lot of work later on.
