The introduction of the "Praxis" tests to certify preservice teachers has added to the controversy over what content should be taught in educational psychology classes. "Praxis II" tests are essentially exit examinations, usually taken between the junior and senior year to ensure that students know their specialty content areas and/or appropriate pedagogy for teaching before becoming certified. "Praxis II" tests of "Principles of Learning and Teaching" (ETS, 1999) encompass the content that students are expected to know in areas that have traditionally been educational psychology. Tests are geared toward specific age groups. Topics cover four broad categories (organizing content knowledge for student learning; creating an environment for student learning; teaching for student learning; and teacher professionalism). These assessments use a case study approach to measure students' general pedagogical knowledge. The author suggests that the "Principles of Learning and Teaching: Grades 7-12 "may be very difficult for typical undergraduates due to lack of experience. She notes that it is important to share with student teachers what kinds of information are emphasized on the test. She also recommends that students be exposed to the case study method before taking the test. (Contains 13 references.) (SM)
