摘要

Although growing numbers of secondary school mathematics teachers andstudents use calculators to study graphs, they mainly rely on paper-and-pencil whenmanipulating algebraic symbols. However, the Computer Algebra Systems (CAS) oncomputers or handheld calculators create new possibilities for teaching and learningalgebraic manipulation. This study investigated the views of Turkish prospective sec-ondary mathematics teachers on the use of advanced calculators with CAS in algebrainstruction. An open-ended questionnaire and group interviews revealed prospectiveteachers' views and beliefs about when and why they prefer three possible uses of CAS—black box, white box, or Symbolic Math Guide (SMG). The results showed that partici-pants mainly preferred the white box methods and especially SMG to the black boxmethod. They suggested that while the black box method could be used after studentsmastered the skills, the general white box method and SMG could be used to teachsymbolic manipulation.
