Abstract
In this paper, we propose a MMS (Multimedia Message Service) -based Interactive Mobile Learning model for adult learners to update their CPR (Cardiopulmonary Resuscitation)-related knowledge and skills. Informed by N. A. Crowder's (1960) branching version of B. F. Skinner's (1958) Program Instruction approach, we designed an interactive learning process that requires the learners to make series of decisions and then be informed by the system of their consequences, thereby achieving "by making and reflecting on mistakes". A feasibility study was conducted in three phases with volunteered adult learners being engaged in the MMS learning process. Through the process of learning content development and our analysis of the learner data, we gained better understanding in the feasible activity modes and the factors that may potentially affect the learning process and learner perceptions toward the learning model.
