Examining the Hypothesis of Parental Favoritism
Author(s)
Abstract
This interrupted case study is based on a journal article on the parenting behavior of American coots. Working through the case, students develop hypotheses and design experiments to test their hypotheses as they are given pieces of the case in an interrupted, or progressive disclosure, case format. The case teaches students about the scientific method. As such, it would be useful in any course where one wishes to emphasize how scientists go about solving problems. The subject matter of the case makes it suitable for courses in biology, especially those focusing on evolution and ecology, and the case can be used with both science majors and non-science majors.
Objectives
- Help students develop a clear, rigorous, and structured approach to solving problems.
- Give students practice in designing experiments.
- Give students practice in making predictions and interpreting data.
- Give students an explicit experience with the hypothetico-deductive method of reasoning, i.e., “the scientific method,” where a question is asked, a hypothesis suggested, predictions or deductions made in light of the hypothesis, tests accomplished, and the data evaluated as to whether it supports or rejects the hypothesis.
