A number of validated survey instruments for assessing technological pedagogical content knowledge (TPACK) do not accurately discriminate between the seven elements of the TPACK framework particularly technological content knowledge (TCK) and technological pedagogical knowledge (TPK). By posing simple questions that assess technological, pedagogical, and content knowledge (TK, PK and CK) the logical associations forming the TPACK framework can be used to synthesise TPK, TCK survey items that are inherently valid. This process can further be applied to constructing TPACK survey questions that agree closely with those from validated surveys.
