Ontario Curriculum Expectations
About This Topic
Ethics in Science and Technology challenges students to look beyond 'can we build it?' to 'should we build it?' This topic covers the societal impacts of scientific advancement, from the environmental cost of electronic waste to the ethical dilemmas of AI and genetic engineering. It encourages students to consider who benefits from new technologies and who might be left behind or harmed. This is a crucial part of the Ontario curriculum's goal to develop scientifically literate citizens.
Students also explore the concept of 'technological stewardship' and the importance of including diverse perspectives, including Indigenous and Francophone voices, in scientific decision-making. This topic is inherently discussion-based and benefits from structured debates and role-plays. Students grasp the complexity of these issues faster when they have to defend a position that isn't their own, helping them see the multiple 'truths' in any ethical dilemma.
Active Learning Ideas
Formal Debate: The Right to Repair
Students debate whether companies should be legally required to make their devices easy to repair. They take on roles as tech CEOs, environmental activists, and consumers, exploring the tension between corporate profit and the growing problem of global e-waste.
Role Play: The AI Ethics Board
Students act as a committee deciding whether to deploy a new facial recognition technology in their city. They must consider issues of bias, privacy, and safety, and write a 'recommendation report' that balances these competing ethical concerns.
Gallery Walk: The Hidden Cost of Tech
Students create 'infographic' posters showing the life cycle of a common product (like a smartphone), highlighting the ethical issues at each stage: mining in conflict zones, factory conditions, and disposal in developing nations.
Watch Out for These Misconceptions
Common MisconceptionScience is 'neutral' and doesn't have a bias.
What to Teach Instead
Students often think science is purely objective. Through a collaborative investigation into historical examples (like the exclusion of women or Indigenous knowledge from early research), students learn that the *questions* we choose to ask and the *people* who ask them shape the results.
Common MisconceptionEthical problems will be solved by better technology in the future.
What to Teach Instead
Students may think 'tech will fix it.' A structured discussion can show that ethical problems are human problems; while tech can help, the decisions about how to use it require human values, laws, and empathy, which don't come from an algorithm.
