Multi-Criteria Decision Making Under Uncertainty is a Grade 12 Science 30 resource within an Alberta framework that develops evidence-based decision-making through cross-disciplinary evidence, quantitative reasoning, uncertainty, and critical evaluation.

Reason Through Complex Decisions

Students explore how cross-disciplinary evidence can be synthesized into defensible decisions. They use quantitative reasoning to compare options against multiple criteria while considering the strength and limitations of available evidence.

Uncertainty is treated as an essential part of scientific decision-making. Students identify sources of uncertainty and select conclusions that match the confidence supported by the evidence. They also critique proposals by examining assumptions, limitations, and the logic behind a decision.

Practice Scientific Decision-Making

The worksheet includes multiple-choice questions, true-or-false statements, short-answer responses, a reading passage, matching, a cloze passage, an essay, and a “Did You Know?” section. The varied activities provide opportunities to identify concepts, compare alternatives, evaluate evidence, and communicate reasoned conclusions.

Resources Included

• ✅ Student worksheet focused on multi-criteria decision making under uncertainty
• ✅ Separate PDF answer key
• ✅ Student Notes & Lesson Summary supplement
• ✅ Separate Teacher Guide with Learning Objectives, Teaching Tips, Discussion Questions, and Common Mistakes

Use in Science 30

This resource can be used for Science 30 instruction, independent practice, review, lesson reinforcement, or assessment. The student supplement provides additional support for key learning, while the Teacher Guide helps instructors plan instruction, guide discussion, clarify objectives, and address common mistakes.

By combining quantitative comparison with evidence synthesis, uncertainty analysis, and proposal critique, this resource gives Grade 12 students structured practice applying scientific reasoning to decisions where evidence, assumptions, limitations, and trade-offs must be considered.
