Teacher GuideWeek 14 · Investing, Diversification, and Market Risk
Essential question: How can a long-term investor pursue growth without confusing uncertainty, volatility, speculation, and fraud?
Instructional caution: Distinguish factual definitions, legal holdings, economic relationships, value judgments, and policy preferences. Do not grade students for political viewpoint; grade evidence, accuracy, reasoning, citation, and disciplinary method.
Mastery evidence
- Expected return generally rises with risk, but risk never guarantees reward.
- Diversification reduces asset-specific risk but does not eliminate broad market risk.
- Investment suitability depends on goals, time horizon, liquidity, capacity for loss, taxes, and fees.
Source / model emphasis
Create three diversified model portfolios for short, medium, and long horizons and justify risk, liquidity, fees, and rebalancing.
Compare fund expense ratios and calculate their long-term effect under identical gross returns.
Daily Teaching Notes
Monday · Frame the Inquiry
Instructional aim: Define the Week 14 problem, establish the relevant institutions or economic relationships, and construct an initial answer to the essential question.
Evidence of learning: Identify one distinction that prevents a common oversimplification of this topic.
Support: Provide a vocabulary preview, chunked text, text-to-speech, and claim/evidence sentence frames.
Extension: Identify a competing theoretical interpretation and describe what evidence could distinguish it.
Tuesday · Source, Case, or Contract Laboratory
Instructional aim: Evaluate a primary record, legal case, policy document, contract, or institutional source for authority, evidence, context, and limitation.
Evidence of learning: State one claim the focal record supports and one claim it cannot establish alone.
Support: Define specialized language, provide a structured annotation guide, and allow oral rehearsal before writing.
Extension: Locate a source from a different institutional or social position and explain how it confirms, complicates, or contradicts the first.
Wednesday · Model, Measure, and Test
Instructional aim: Interpret a quantitative model, institutional process, financial calculation, or policy tradeoff without confusing description and causation.
Evidence of learning: Explain which conclusion remains valid after the changed assumption and which conclusion does not.
Support: Provide labeled examples, formulas or process steps, and a partially completed model.
Extension: Perform a sensitivity analysis or compare an alternative policy/institutional design.
Thursday · Argument, Deliberation, and Policy
Instructional aim: Construct and defend a precise claim using disciplinary evidence, a counterclaim, and a proportionate conclusion.
Evidence of learning: Explain why the counterclaim deserves a response rather than dismissal.
Support: Use claim-evidence-reasoning frames and permit an audio or oral draft before the final written product.
Extension: Rewrite the recommendation for an audience with a different role, jurisdiction, time horizon, or risk tolerance.
Friday · Assess, Correct, and Transfer
Instructional aim: Demonstrate weekly mastery, correct misconceptions, and transfer the central concept to a new case.
Evidence of learning: Apply the week’s reasoning to this mastery action: A student matches risk to time horizon and capacity for loss, diversifies broadly, and verifies fees and registration before investing.
Support: Allow extended time, reduced-distraction setting, read-aloud where appropriate, and repeated attempts after documented correction.
Extension: Write one high-quality examination question and an answer key explaining why each distractor is wrong.
