Blended learning, a convergence of e-learning approach and face-to-face learning, has been regarded as a new paradigm in modern education. The degree of learners' satisfaction with blended learning played a crucial role in evaluating the effectiveness of blended learning adoption. Therefore, this study examined the primary factors affecting learners' satisfaction in blended learning environment. A comprehensive questionnaire was used to assess the impact of six dimensions such as learner, instructor, course, technology, design and environment, on perceived e-learner satisfaction specifically on the e-learning component within the blended learning environment. The respondents for this study were generally young with an average age of 20 years old. Results from univariate regression analysis revealed all six dimensions to be positively associated with perceived e-learner satisfaction. Subsequent multivariate regression analysis evidenced only the design dimension to be the critical factor influencing perceived e-learner satisfaction. This study concluded younger generation prioritized the design dimension to be the most critical factor in their satisfaction towards e-learning component in blended learning environment. Therefore, it may be more strategic for institutions to emphasize on the design dimension in their e-learning implementations within the blended learning environment specifically for younger learners.
