Although the objects to be classified here are birds, the concepts gained in the previous exercise are vital to doing this one. Here we not only create a scientific classification scheme for birds, but also evaluate our classification system with the goal to improve the accuracy of it and to understand the interrelationships of a classification and its accuracy.
Students begin by classifying pictures of birds into three categories.
The validation data has been collected with a high degree of accuracy. Finally, the class is led in a discussion concerning the results of this activity. The process may sound quite complicated, especially if we think that classification is simply putting things in arbitrary groups. But use of valid criteria and accuracy are vitally important to doing good science in the area of classification, as in any aspect of science. The following learning and performance objectives correlate to this activity, and support Ohio proficiency test outcomes you may use them to tailor this activity to your local curricular objectives and goals.
