| A case study approach to botany was developed to increase student motivation and student experimental design. Case studies provide a framework for students to return to through out a course. This case study used a current environmental problem, the spread of the exotic species, purple loosestrife, in our local wetlands to grab student's attention. Students asked questions that led them to study the course objectives when researching the answers. Purple loosestrife is an ideal plant for the classroom as it is readily available in our local wetlands and grows quickly from root balls. Students were able to study the plants by growing the small root balls collected from a local pond in the fall.;Student learning was assessed in by comparing written answers pre tests to written answers to journal questions and post tests. The study focused on seven students with a range abilities that represented the class of twenty one students. Students had interest in the purple loosestrife problem and asked thoughtful questions that led them to possible solutions. By designing experiments and solving problems students gained a new lasting, understanding of plants. |
