1.0 IntroductionChapter 1 deals with the introduction of the context of blended learning, i.e. online and face-to-face learning, used by science students cognitive skills of UNIMAS in their university studies. Then, it discusses the problem statement, the research question, the objective of the study which is divided into general objective and specific objective, as well as the definition of terms and the conceptual framework of this research. This chapter also contains the limitations and significance of the study in this research.1.1 Background of the StudyNew advancements in Internet-based technology have also brought challenges and opportunities to education and training, in especially through online teaching. Online learning can be defined both as a type of learning that occurs via the Internet, a network, or only a computer and as synchronous or asynchronous audio, visual, and interactive educational activities (Dziuban, Hartman, & Moskal, 2004 ). The most significant characteristics of online learning are that the teacher and learner are in different physical environments and that communication throughout the teaching/learning process takes place via email, forums and others via the Internet. Online learning is a common method. Since it is able to present course content over a longer period of time than the classroom environment and other methods allowing seven days and twenty-four hours of teaching, it reaches a greater number of learners and ensures a learning environment that is independent of time and place (Dziuban, Hartman, & Moskal, 2004), especially for students. However, online learning environments have disadvantages such as hindering the socialization process of individuals, lack of paper......horpe, RT & Graham, CR (2003).
