Historical Engineering Achievements

Algorithms and computational thinking form the logical backbone of the Digital Solutions course. Students learn to translate human logic into structured, machine-readable processes using pseudocode and flowcharts. This topic emphasises abstraction, where students filter out unnecessary details to focus on the core logic of a problem. It is not just about writing steps; it is about efficiency, scalability, and the elegant application of logic to solve complex tasks.

• Simulation Game
• 25 min · Whole Class

Simulation Game: Human Sorting Algorithm

Students are given cards with random numbers and must organise themselves into a sorted line using only a specific algorithm like Bubble Sort or Quick Sort. They can only communicate through the 'rules' of the algorithm to see how logic dictates physical movement.

Activity 02

• Peer Teaching
• 30 min · Pairs

Peer Teaching: Pseudocode Swap

Pairs write pseudocode for a simple task, such as making a Vegemite sandwich or calculating a GST-inclusive price. They swap their 'code' with another pair who must follow the instructions exactly as written, highlighting any logical gaps or missing steps.

Activity 03

• Stations Rotation
• 50 min · Small Groups

Stations Rotation: Logic Gates and Flowcharts

Set up three stations: one for drawing flowcharts for real-world decisions, one for tracing existing pseudocode to find errors, and one for simplifying complex logic into abstract steps. Groups rotate every 15 minutes to practice different computational thinking skills.

A few notes on teaching this unit

---

Watch Out for These Misconceptions

• Pseudocode must follow strict syntax like a specific programming language.

  Students often worry about commas or brackets in pseudocode. Use peer-review sessions to show that as long as the logic is clear and follows a consistent structure, the 'language' is flexible. The focus should be on the logic, not the grammar.

• A flowchart is just a drawing of what the code does after it is written.

  Many students see flowcharts as a post-coding chore. Hands-on 'unplugged' activities where students must follow a flowchart to solve a puzzle help them see it as a design tool that prevents coding errors before they happen.
