The paper took a semi-grounded theory approach to develop a comprehensive framework of critical factors in adopting podcasting for educational use and showed how these critical adoption factors differ for two groups of users: faculty and students. The paper is theory-rich as it was based on synthesized technology adoption models (i.e., TAM3 and UTAUT) and yet uncovered new adoption determinants. The study also has practical impacts as it can help education administrators to tailor the podcasting adoption plan to different user constituencies.
