The student learns skills and concepts better when they are set in the context of a problem than when treated as ends in themselves. The instructor designs problems in terms of his goals for the laboratory program. Possible imbalances are revealed by detailed analysis of what background the student brings to each problem, what the instructor supplies, what the student does, and what skills and concepts he acquires. The introductory geology laboratory program should provide progression from facts to data and then inferences at several levels. Significant problems can be posed if students are encouraged to help each other in acquiring the necessary tools. A set of three exercises uses the geologic map of Dolores Peak quadrangle, in southwest Colorado, to explore the concept and implications of the geologic contact. The Dolores Peak problem serves as an example in design, preparation of materials, and analysis of a laboratory problem for introductory geology. |
