Sub Strand 3.2: Program Development Overview

Specific Learning Outcomes

By the end of the sub strand, the learner should be able to:

a) Describe the stages of the program development cycle (problem definition, program design, coding, testing, implementation, documentation, maintenance)

b) Write a pseudocode to illustrate the logical flow of an algorithm

c) Represent the logical flow of an algorithm using a flowchart

d) Design algorithms to solve a real-life problem

e) Appreciate the importance of using algorithms in problem solving

Suggested Learning Experiences

The learner is guided to:

• Discuss the stages of the program development cycle (problem definition, program design, coding, testing, implementation, documentation, maintenance)
• Discuss characteristics of an algorithm (input, output, finite, definite, effective)
• Discuss the keywords (start, variables, input, processing, output, end) used in pseudocodes and demonstrate how they are used to represent algorithms
• Use the keywords (start, variables, input, processing, output, end) to write a pseudocode that illustrates the logical flow of an algorithm
• Discuss the standard symbols (start, input, processing, decision, repetition, continuation, output, end) used in flowcharts and demonstrate how they are used to represent an algorithm
• Draw a flowchart to illustrate the logical flow of an algorithm
• Write an algorithm on how traffic lights enhance road safety
• Use pseudocodes and flowcharts to solve a real-life problem
• Discuss the significance of algorithms in problem solving

Suggested Key Inquiry Questions

1. How are programs developed?
2. Why are algorithms designed?

Core Competencies to be Developed

• Creativity and Imagination: Learner undertakes tasks while working on a problem to find a solution by constructing an algorithm using a flowchart and pseudocode
• Critical Thinking and Problem Solving: Learner seeks alternative ways of using algorithms in problem solving

Values

• Love: The learner understands and appreciates others as they discuss the significance of algorithms in problem solving
• Integrity: The learner demonstrates honesty when participating in a group activity involving drawing and discussing symbols in a program flowchart
