Classroom Applications

This project modeled an inquiry learning technique in which each student attempted to come up with 50 questions around a topic that they had been introduced to. In our case the topic was human impact on ecosystems. After reviewing and eliminating some questions based on the feasibility of actually completing a short-term project with limited resources, each person then ranked their top 4-5 most interesting possibly answerable questions. Small groups of 4 then reviewed their respective questions and agreed to focus on one specific question to actually design an experimental study about. Constraints of time, equipment and expertise in identification dictated the nature of the study. There was also much discussion and interaction with the teacher/group leader in order to design the study along the best scientific practices. The process used to develop the project and the constraints make it fully applicable to a classroom situation.

Most local environments have introduced species and native species that could be studied in a similar way. During the course of a project such as this, students would be able to develop their science skills and also practice and develop a better understanding of scientific processes. For example, in doing this project we used keys to identify the tree species and the insect orders. Using a key depends upon both the use of observation skills and an understanding of the characteristics used in identification as well as an understanding of the logic of a dichotomous key. Simple pictorial insect keys are available for use with middle school children and simple short keys for insects are available for high school students. Censusing or sampling techniques are applicable to the teaching of several math and science concepts. The development of the methods for sampling to be used can add to student’s repertoire of science skills. Data collection, graphing and analysis can also be practiced.
