Pengembangan Sistem Pembelajaran dalam Jaringan pada Materi Teori Graph

Discrete mathematics is the basic mathematical subjects in which includes many of the basic concepts of mathematics. The number of concepts to be learned is not offset by the time allocation of face-to-face learning. To overcome these problems then do blended learning (combination of face to face learning and online learning). In order for the implementation of learning activities as expected, then it needs to design the learning system. The purpose of this research is to produce online learning system in discrete mathematics courses on graph theory material. This is research and development by adapting and modifying the four D model that consists of define, design, develop, and disseminate by Thiagarajan. This study is limited to the definition, design and developstage only. Definition stage consists of five main steps, namely front-end analysis, learner analysis, concept analysis, task analysis, and specifying instructional objective. At the design stage includes constructing criterion-referenced test, media selection, format selection, and initial design. The development phase consists of two stages, validity test and development test. The results of this research is a learning system in the network (online) on the material graph theory that can be applied to discrete mathematics lectures which implement blended learning.
