Limitations of GDP as a Measure
Students explore the limitations of GDP as a sole indicator of national well-being, considering non-market activities and inequality.
Key Questions
- Evaluate whether a rising GDP always translates to a higher quality of life.
- Analyze the trade-offs created between short-term growth and long-term sustainability.
- Assess who benefits and who bears the costs of a rapidly expanding economy.
ACARA Content Descriptions
About This Topic
Machine Learning (ML) introduces students to the concept of algorithms that 'learn' from data rather than following static, pre-written rules. In Year 10, the focus is on understanding the basic logic of classification and prediction, and how the quality of 'training data' directly impacts the outcome. This aligns with ACARA's requirements to investigate how digital systems represent and process data (AC9DT10K01).
A significant part of this topic is the ethical consideration of algorithmic bias. Students explore how historical biases in data can lead to discriminatory outcomes in AI systems, such as facial recognition or hiring algorithms. This topic is best taught through hands-on experimentation with 'teachable machines' and structured debates about the role of AI in society, helping students move from passive users to informed critics of technology.
Active Learning Ideas
Simulation Game: Training the Trainer
Using 'Google Teachable Machine', students train a model to recognize different hand gestures. They then intentionally 'poison' the data with incorrect examples to see how it breaks the model's accuracy.
Formal Debate: The Ethics of AI
Divide the class to debate: 'Should AI be allowed to make decisions in the justice system?' Students must research real-world examples of algorithmic bias to support their arguments.
Inquiry Circle: Bias Detectives
Groups are given a scenario (e.g., an AI that predicts who gets a loan). They must identify three potential sources of bias in the training data (e.g., postcode, gender, or age) and propose a way to make it fairer.
Watch Out for These Misconceptions
Common MisconceptionAI is 'smarter' than humans and always objective.
What to Teach Instead
AI is only as good as the data it is fed. If the data is biased, the AI will be biased. Using a 'sorting' activity with biased criteria helps students see how 'objective' rules can produce 'subjective' and unfair results.
Common MisconceptionMachine learning and traditional programming are the same.
What to Teach Instead
In traditional coding, we write the rules. In ML, the computer finds the rules. A 'rules vs patterns' comparison activity helps students distinguish between these two fundamental approaches to computing.
