AbstractWith the proliferation of mobile computing technology, mobile learning (m-learning) will play a vital role in the rapidly growing electronic learning market. However, the acceptance of m-learning by individuals is critical to the successful implementation of m-learning systems. Thus, there is a need to research the factors that affect users’ intention to use m-learning. Based on an updated information system (IS) success model, data collected from 350 respondents in Taiwan were tested against the research model using the structural equation modeling approach. The data collected by questionnaire were analyzed to check the validity of constructs. Then hypotheses describing the relationships between the identified constructs and users’ satisfaction were formulated and tested. Keywordsm-learning, information system success, users’ satisfaction, perceived value. I. INTRODUCTION OBILE technologies are a future in e-learning technologies [1]. M-learning has been gaining appeal among younger generations who have grown up using portable video game devices and wireless technology. In this sense, m-learning appeals not only to those who need learning portable, but to those who have grown up with a cognitive disposition towards using mobile devices whether or not they have the need for true portability in their learning [1]. The term m-learning is coined to describe the convergence of mobile technologies with e-learning. The development of m-learning products and the provision of m-learning opportunities are expected to be rapidly expanding. In business, for example, the importance of m-learning has been raised as many companies look into mobile technologies to support mobility of their Knowledge Management (KM) Chin-Cheh Yi is an associate professor of the Department of Applied Technology and Human Resource Development, National Taiwan Normal University, R.

The use of ICT facilitates knowledge sharing and cooperative learning among KM participants [3] [4]. DeLone and McLean’s model of information system success has received much attention amongst researchers [5]. This study provides the first empirical test of an adaptation of DeLone and McLean's model in the user-developed application domain. In a recent paper, DeLone & McLean discussed many of the important IS research efforts that apply, validate, challenge and propose enhancements to their original model, and proposed an updated DeLone & McLean IS success model[6]. With the prosperity of e-commerce systems, IS researchers have turned their attention to developing, testing and applying e-commerce systems success measures [7] [8] [9]. Although m-learning is generally considered to increase the performance of learners by making learning accessible, no research has been done in relation to m-learning success factors from the learner's perspective. The users are knowledgeable about what factors in Information System (IS) are affecting their satisfaction [10]. Studying m-learning success from the users’ perspective is critical to understand the value and efficacy of management actions and investment in m-learning. The main purpose of this study was to respecify and validate a multidimensional m-learning system success model based on the IS success and marketing literature. This paper is structured as follows. First, this study reviews the development of IS success models, discusses the primary debates on Seddon’s[11]Perceived Usefulness and DeLone & McLean’s [5][6] IS Use constructs, and considers the challenges and difficulties facing DeLone & McLean’s model[6]. Second, based on prior studies, a research model of e-commerce system success and a comprehensive set of hypotheses are proposed. Next, the methods, measures and results of this study are then presented. Finally, the results are discussed in terms of their implications for research and managerial activity. Focusing on technology aspects of m-learning, no research has been done in m-learning success factors from the users’ perspective. The objective of this study is to investigate key determinants of m-learning success perceived by users. II. LITERATURE REVIEW A.
