Rethinking the use of Concept maps

MariyaBurdina

University of Central Oklahoma

Temporal contiguity principle

Students learn better when corresponding words and “pictures” are presented simultaneously rather than successively

• Mayer, 2004
• A concept map is a diagram showing the relationships among concepts
• Satisfies temporal contiguity principle

GDP

Nominal GDP

Real GDP

GDP Deflator

Inflation

Spatial principle
• Students learn better when corresponding words and pictures are presented near rather than far from each other
• Mayer, 2004
Conceptual chapter map
• A graphical tool for organizingconcepts
• Provides brief explanation of the concepts
• Satisfies temporal contiguity principle
• Satisfies spatial principle
Use
• Review tool for a topic or a chapter
• Drawn on the board by instructor
• Completed with the help of students
• Distributed to students
• Used during in-class assignments/quizzes
• Option for “revising” a chapter map
Production Possibility Frontier
• Slope
• Constant
• Increasing
• Points:
• inside
• outside
• on PPF
• Corners
• Shifts in PPF
• Affecting one good
• Affecting both goods

Production Possibility Frontier show every possible combination of two goods produced by a country

Shifts of PPF occur when either technology or amount of resources is changed

Intercepts:

Red – max production of good A when B = 0

Orange - max production of good B when A = 0

Possible but not efficient: Green and every point inside PPF

Possible and efficient: Black, Red, Orange and every point on PPF

Not possible but desirable: Blue and every point outside PPF

Slope of PPF shows the Opportunity Cost

Increasing OC

Affecting one good

Affecting both goods

Constant OC

Demand, Supply, Market Equilibrium
• Law of demand
• Shifts of demand curve
• Law of supply
• Shifts of supply curve
• Market equilibrium
• Surplus
• Shortage
• Changes in market equilibrium

Market

Demand

Supply

Changing price:

Increasing price decreases Qd

Decreasing price increases Qd

Changing price:

Increasing price increases Qs

Decreasing price decreases Qs

Changing Demand:

Number of consumers

Popularity

Future prices

Change in income:

- Normal goods

- Inferior goods

Changing Supply:

Number of Sellers

Better technology

Future prices

Input prices

Prices/popularity of similar goods

• Changes in Equilibrium
• Algorithm:
• Draw the D and S curves and show the equilibrium
• Decide whether event shifts S curve or D curve or both
• Decide in which direction curve(s) shifts.
• Illustrate the shifts using the graph
• Use supply-demand diagram to identify new equilibrium P and Q.
“Evidence”
• Students use concept maps in class
• A-ha moments
• Reduced load of questions during the in-class assignment
“Evidence”
• Normal vs. Standard Normal vs. Uniform
• Hypothesis testing
• Intermediate Microeconomics
• Max utility vs. Min cost
• EV vs. CV
Practical strategies
• Introduce maps as a review before in class assignment
• Assign “revise” the map instead of the “create” the map
• Keep it simple (Coherence Principle)
• Students learn better when extraneous material is excluded rather than included
• Think what’s important and what is not. Only the most important things should be included in the map
Practical strategies
• Keep it colorful to emphasize important points
• Make sure that assignment can be answered with concept map
• Provide links and definitions; allow space for student to fill in with examples
“Evidence”
• Principles of Micro
• PPF
• Demand, Supply and Equilibrium
• Elasticity
• Surplus
• Public goods
• Cost
• Market comparison
• Each type of market
• Principles of Macro
• GDP
• Inflation
• Productivity and growth
• Savings and Investment
• Unemployment
• Open market economy
Next step: Class Experiment
• Conceptual chapter map in Principles of Macroeconomics
• 2 classes of students:
• Chapter map for in-class assignment for Class 1
• Notes for in-class assignment for Class 2
• No notes for the test
• Chapter map for quiz for Class 1
• Notes for quiz for Class 2
• No notes for the test
