The use of Short Blended Online Training (SBOT) for the development of Technological Pedagogical and Content Knowledge (TPACK) is a promising approach to facilitate the use of e-learning by academics. Adult learners prefer the blend of pedagogies such as the presentation, demonstration, practice and feedback if they are structured and instructor-led with an efficient training length. In this paper, we suggest that SBOT has the potential to create a highly preferred environment for training if adult learning principles are considered. The study explores the evaluation of this mode of training by using Technology Acceptance Model (TAM). The results show a great acceptance for this mode of training. Moreover, in practice, dual training modes can be offered for TPACK development programs, which may consist of face-to-face training and SBOT. (Contains 4 tables.)
