Using Pseudozoids to Teach Classification and Phylogeny to Middle School Students
Freidenberg, Rolfe Jr.; Kelly, Martin G.
Online Submission
This research compared the outcomes of teaching middle school students two different methods of classification and phylogeny. Two classes were randomly selected and taught using traditional methods of instruction. Three classes were taught using the "Pseudozoid" approach, where students learned to classify, develop and read dichotomous keys, and make evolutionary diagrams using artificial organisms. Here, the pseudozoids are twenty-six different artificial organisms that have body shapes representing the twenty-six letters of the alphabet. For each method, students were divided into small cooperative learning groups based on my estimation of student ability to learn and work cooperatively (i.e. high learner, medium learner, and low learner). A pre-test and test were administered to all classes. The data was used to measure the amount of learning associated with the traditional method or Pseudozoid method. A survey was given to all students after the unit on classification and phylogeny was completed to measure student satisfaction. No significant differences in test results, learning, or student satisfaction were found between the types of teaching method used. That no significant differences were seen could be due in part to the similarity in the teaching methods or to test questions that were unable to detect slight differences in student learning. The following are appended: (1) Pre Test and Test Given to All Students; (2) List of Objects Used in Sorting Activity; (3) Example of Sorting Activity, Using Objects in Appendix 2; (4) Classification Homework Given to All Students; (5) A Classified Paper Activity; (6a) Branching Diagram(Phylogeny) for Four Animals; (6b) Phylogeny Practice Activity; (6c) Dichotomous Key for 10 Common Mammals; (7) Classifying Shoes Activity; (8a) Phylogeny Homework; (8b) Alien Life-Form Homework; (9a) Cut and Paste Phylogeny Activity; and (9b) Classification and Phylogeny Test Review. (Contains 6 figures and 11 tables.)
