SHS1 Computing · Semester 2 Week 11: App Development

Lesson notes

Learning Objectives

Indicator: 1.2.2.LI.2 - Implement Algorithms into programmes with the use of flowcharts, pseudocode and programming languages such as Python, HTML, etc. Explain the steps in planning a programme putting actions in the right order

By the end of the lesson, learners can:

Identify and sequence the steps for planning a programme (analysis, design, coding, testing) in the correct order.
Convert a given algorithm into a flowchart using standard flowchart symbols (start/end, process, input/output, decision).
Translate a simple algorithm into pseudocode for problems such as finding the sum of two numbers or the area of a rectangle.
Implement a simple algorithm as a working Python program using variables and appropriate data types (integers, strings).
Test a completed program with sample inputs and identify and correct errors in the sequence of steps (debugging).
