Since the emergence of computers in schools during the 1980's, there have been considerable developments by education systems and schools to develop policies and expectations for the use of information and communication technologies (ICT) to enhance learning and teaching. These have not always translated into practice, which has resulted in a focus on the need for improvements in preservice teacher education programs and professional development of practising teachers. This paper starts from the premise that most teacher education have been constrained by using Pedagogical Content Knowledge (PCK) developed by Shulman [1] [2] prior to the dynamic technological changes enabled by the Internet. The authors present the case for the importance of Technological Pedagogical Content Knowledge (TPACK) [3] [4]. Subsequently, the paper provides guidance for auditing the TPACK capabilities of teacher education students through the presentation of an instrument developed, and provides a summary of some of the findings of a study undertaken using that instrument.
