Abstract:

“The article presents a study regarding the use of multiple representations (MRs) with technology. It mentions that forty prospective mathematics teachers participated in the course designed using the Technological Pedagogical Content Knowledge (TPCK) wherein they were enrolled in a teacher preparation programme in a state university in Istanbul, Turkey. The result of the study indicates that the content of teacher preparation or professional development programs could be prepared by Ainsworth’s taxonomy. It says that the three main functions of MRs defined by Ainsworth’s taxonomy include to , constrain, and construct.”
