Mark Maier, Glendale Community College
After predicting what the unemployment rate will be for students in the class, a confidential survey modeled on the Current Population Survey questions is used to gather data about each student's employment. Students use this data to measure the class unemployment rate and then assess its accuracy.

The US economy during your lifetime part of Teaching Methods:Interactive Lecture Demonstrations:Examples
Mark Maier, Glendale Community College
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.
