Blended learning is not just simply combining face-to-face learning with online learning. The challenge is to determine the most appropriate blended learning strategies to achieve a series of desired learning outcomes. Blended learning designers utilize a model of criteria as a guideline to answer to this challenge. This research was aimed to develop a proposed model of criteria for determining the appropriate blended learning strategy. Hence, the research questions become: 1) Is the model created fitting a conceptual framework? and 2) Is the model created effective and implementable? Consequently, formative evaluation techniques were employed to answer these research questions, i.e. experts review, one-on-one evaluation, and field test. These methods were used to collect descriptive and formative data. This study was followed by 7 instructional designers and e-learning experts as well as 235 lecturers as respondents. Upon completing a series of formative evaluations, result of this study showed that the model created is conceptually fitting, effective and implementable as a lecturer's guide in determining the appropriate blended learning strategy. http://pubs.sciepub.com/education/6/3/5/education-6-3-5.pdf asynchronous learning blended learning e-learning instructional design model synchronous learning
