Active learning ideas

Introduction to Demand: Consumer Behavior

Active learning works for this topic because students need to internalize how abstract factors like income and tastes translate into real market behavior. When they physically simulate buying decisions or graph shifts themselves, they connect theory to experience faster than with lectures alone.

Market Simulation: Demand Shifts

Divide class into buyers and sellers of a product like soft drinks. Introduce scenarios such as income boosts or cheaper substitutes, then have buyers signal new quantities demanded on graphs. Groups plot before-and-after curves and discuss shifts.

Explain how changes in income or tastes affect the demand for a product.

Facilitation Tip

During Market Simulation: Demand Shifts, circulate and listen for students who justify their buying choices using terms like 'substitute' or 'inferior good' to ensure the activity reinforces correct economic language.

What to look for

Provide students with a scenario: 'The price of coffee beans increases significantly.' Ask them to draw a demand curve for coffee, showing the effect of this price change. Then, ask them to explain in one sentence whether this is a movement along the curve or a shift.

Graphing Pairs: Quantity vs Shift

Pairs receive demand schedules and graph base curves. One partner changes price for movement along the curve; the other alters income or tastes for shifts. They label changes and predict new equilibrium quantities.

Differentiate between a change in quantity demanded and a shift in the demand curve.

Facilitation Tip

For Graphing Pairs: Quantity vs Shift, provide graph paper with pre-labeled axes to save time and reduce frustration, allowing students to focus on interpreting the shifts.

What to look for

Present students with a list of factors (e.g., 'increased advertising', 'lower price of a competitor's product', 'rise in average household income'). Ask them to identify which factors would cause a shift in the demand curve for smartphones and which would cause a movement along it.

Case Study Carousel: Real Goods

Set up stations with products like smartphones or coffee. Groups analyze how income rises or substitute prices change, drawing demand curves. Rotate stations, adding peer feedback on predictions.

Predict the impact of a substitute good's price change on a product's demand.

Facilitation Tip

In Case Study Carousel: Real Goods, assign each group one product to research so they can present concrete examples of demand determinants like advertising or seasonal trends.

What to look for

Pose the question: 'Imagine you are a product developer for a popular video game. How might a change in the average age of your target audience affect the demand for new game releases? Explain your reasoning using economic terms.' Facilitate a brief class discussion on their responses.

Whole Class Vote: Taste Changes

Poll class on demand for a snack at different prices, then introduce a taste trend via video clip. Revote and graph the shift collectively on a shared board.

Explain how changes in income or tastes affect the demand for a product.

Facilitation Tip

During Whole Class Vote: Taste Changes, ask students to physically move to different sides of the room to represent their preferences, making the abstract concept of changing tastes visible.

What to look for

Provide students with a scenario: 'The price of coffee beans increases significantly.' Ask them to draw a demand curve for coffee, showing the effect of this price change. Then, ask them to explain in one sentence whether this is a movement along the curve or a shift.

A few notes on teaching this unit

Teachers often start by modeling a simple demand curve on the board, then gradually introduce scenarios where students predict shifts or movements. Avoid rushing to formal definitions before students have grappled with the concepts through examples. Research suggests that students grasp the law of demand better when they experience price changes in a low-stakes simulation first, rather than analyzing graphs alone.

Successful learning looks like students confidently distinguishing between movements along a demand curve and shifts of the curve. They should explain why certain goods react differently to price changes and articulate how non-price factors influence demand in real-world examples.

Watch Out for These Misconceptions

• During Market Simulation: Demand Shifts, watch for students who claim that lowering the price of a product shifts the demand curve. Redirect them by asking, 'Did the entire willingness to buy change, or did people just buy more at the lower price?'

  During Market Simulation: Demand Shifts, clarify that when students respond to a price change by buying more or less of a product, they are demonstrating movement along the curve. Use the simulation’s price tags to point out that the curve itself hasn’t moved, only the quantity demanded at each price.

• During Market Simulation: Demand Shifts, watch for students who assume higher income always increases demand for all goods. Redirect them by asking, 'Would you take a taxi more or less if your income doubled? What if the taxi prices stayed the same?'

  During Market Simulation: Demand Shifts, provide budget scenarios where students compare normal goods (like organic fruit) with inferior goods (like instant noodles). Ask groups to debate which goods fit which category and why, using their simulation results to test predictions.

• During Graphing Pairs: Quantity vs Shift, watch for students who think that a change in the price of a substitute shifts the demand curve for the original good. Redirect them by asking, 'If the price of apples rises, do people buy more apples or more oranges at the same apple price?'

  During Graphing Pairs: Quantity vs Shift, have students graph the demand for apples before and after a price change in oranges. Ask them to label the axes clearly and mark the change in quantity demanded for apples to show that the demand curve for apples hasn’t shifted, but the quantity demanded has.
