The US economy during your lifetime part of Pedagogy in Action:Library:Interactive Lecture Demonstrations:Examples

Students predict the best graphical representation of US real GDP/capita during the last twenty years, choosing from graphs showing: cyclical decline, cyclical change with no net change, cyclical increase, or erratic wide fluctuations. Using actual US data, students graph real GDP/capita to find out the actual pattern: a rising series with periodic dips, not a flat series, a falling series, or a highly erratic series as students often predict. Students then reflect on why this pattern is often misunderstood and why it may not fully describe the well-being of the US population.
