"A background in the economic debates and literature of the past 20 years and how those debates have shaped what we as a profession believe; a solid training in the models which they will be beaching to undergraduates; a knowledge of economic institutions and the role institutions play in the economy; an ability to communicate the central ideas conveyed in introductory and intermediate micro and macro [courses]; knowledge of the alternative approaches in economics and an ability to compare and contrast different approaches; and a knowledge of econometrics, and limits of econometric testing."
The petitioners warn they will structure their "hiring practices to favor students who have trained in those areas and skills that are most useful in teaching undergraduates." The signers, some who have contributed teaching ideas to "The Grapevine," are from a cross section of undergraduate colleges including some of the best--Amherst, Bates, Davidson, Middlebury, Smith, Washington and Lee, Wesleyan, and Wellesley. Whether this "Magna Carta" has any effect on graduate instruction remains to be seen, but it's an interesting development and one to follow.

About two-thirds of the responding departments employ at least one assessment method beyond student evaluations, such as classroom visits by faculty, videotaping, or statements of teaching philosophy. Professor White sorted departments into three groups based on the quality of the Ph.D. program: the top 20, 21 through 50, and below 50; then he looked for any link between program quality and the use of teaching assessment tools. Only 27% of departments in the top 20 used something beyond student ratings, compared to 59% of the 21 through 50 group and 76% of the bottom group. For example, none of the top 20 departments used a classroom visit, but one-third of other departments did.
White concluded that most Ph.D.-granting departments are devoting more time and resources to assessing teacher effectiveness, despite their uncertainties about the validity of their evaluation systems. Also, the higher the quality of the Ph.D. program, the less likely the department sought feedback beyond that provided by student evaluations. This latter issue may ties back into the problems stated by the petitioners troubled about teachers preparation.

Above all, remember that you are testing students' knowledge of economics, not their verbal skills. Foreign students have particular problems untangling the wording of needlessly complicated multiple-choice exams. During the exam, you want students to think about economics, not try to divine sentence construction.
John Neal of Lake Sumter Community College in Leesburg, Florida, notes that inflation is merely a change in the length of the financial measuring rod. So why would this change pose problems for decision makers? To answer that question he draws an analogy between unanticipated inflation and an arbitrary change in the length of a yardstick. He asks students to consider how a textile manufacturer might be affected by an arbitrary change in the length of the basic unit of measurement in that industry, the yard. How would such a change affect machinery settings, the quantity ordered, and the amount produced? Professor Neal sensationalizes his question by dramatically breaking a wooden yardstick "into as many pieces as strength permits." He then discusses the specific planning difficulties posed by unanticipated inflation.
John Jascot of Capital Community-Technical College in Hartford, Connecticut, says he gets especially excited teaching students about the relationship between production and cost. After developing the three stages of the total product curve, he goes through the various types of short-run costs. To show the transition from production to cost, he draws a transparency of the total product curve and holds it up to the class. Then he flips it over so that output appears on the horizontal axis instead of on the vertical axis. He has integrated this transition with spreadsheets, which helps address "what it?" questions.
Eric K. Steger of East Central University in Ada, Oklahoma discusses a rise in the minimum wage as follows. Suppose the minimum wage is set above the equilibrium wage. The result is unemployment in this market. But he notes that those unemployed at the minimum wage often work in jobs such as baby-sitting that pay less than the minimum. His point it that, while unemployment may increase somewhat with a rise in the minimum wage, the distortion created by the minimum wage is reduced if workers accept jobs below the minimum.
John Henzel of Athens Area Technical Institute in Athens, Georgia, toured Russian last year, and in class he now shows slides from his trip that contrast economic life in Russia with life in the United States. Also, in his macro course he assigns a paper "Why I am an economic policy activist or nonactivist (or some combination of the two)."
To explain price discrimination, John Virkler of Chowan College in Murfreesboro, North Carolina, discusses the different ticket prices at baseball games, such as ladies night and lower prices for little leaguers in uniform and for those in military uniform. The Richmond Braves, to boost Sunday attendance, offered discounts for those bringing that week's church or synagogue bulletin. As an example of diminishing marginal utility, he points out that even if baseball games were free, most people would not go to games seven days a week.
As another example of price discrimination, William J. Field of Depauw University in Greencastle, Indiana, notes the variety of products around the campus that are sold at a student discount. He sent along an add for a bed and breakfast that offers students a 40% discount. He says that such examples lead to a discussion of the price elasticity of demand.
Charles W. Johnston of the University of Michigan, Flint, recommends the following study idea, which he picked up years ago while studying the psychology of learning. As a student, he found that reviewing his notes right before going to sleep was quite useful. He claims that while we sleep, our brains process this information, learn it, and store it for future reference. He thinks that learning while sleeping is quality study time, with no interruptions.
Paul Taperek of south Florida Community College in Avon Park, Florida, scans the daily newspaper for articles that tie into the week's class objectives. He duplicates these articles to provide students with material for class discussions. He says this moves economics beyond theory and into practice. Duncan Tye of Western Carolina University in Cullowhee, North Carolina, does the same thing and, in addition, gives students a series of questions to answer.

Stephen M. Miller of the University of Connecticut, Storrs, plays what he calls "The Billionaire Game" to help introduce time preference, life-cycle consumption patterns, and other time-related ideas. Here are the rules. Each student must at the outset surrender any personal assets, but each receives a billion dollars to spend over a lifetime, provided each earns no income (from work, interest, dividends, or any other income source). Each student also knows the exact date of his or her death, and any money not spent at that time reverts to the benefactor. After explaining the rules, Professor Miller draws three charts on the board representing increasing, decreasing, and constant lifetime spending patterns. In each case the area under the spending stream totals $1 billion. Students then vote on the preferred consumption pattern. The chart with the declining consumption pattern usually wins by a wide margin. After the vote, the instructor can discuss questions such as why interest rates reward those who forego present consumption, how the actual consumption pattern over a lifetime combines elements from the three patterns voted on, and why student would bother going to college if they prefer present to future consumption.
