Although e-learning is popular today, it still needs more analysis to draw a better outline. In this paper we classified six phases which e-learning designers should consider while designing instruction. There are seventeen instruction approaches within these phases. They are (1) system phase：synchronous approach and asynchronous approach, (2) procedure phase：blended learning approach and pure on-line learning approach, (3) control phase： teacher-centered approach and student-centered approach, (4) communication phase：student to student approach, student to teacher approach and student to content approach, (5) media phase：text-based approach, video-based approach, multimedia approach and virtual reality approach, (6) pedagogy phase：expository approach, inquiry approach, simulation approach and adaptive approach. Regarding the above, the SWOT strategy was used to compare the effectiveness of instruction approaches among these phases. The results of this comparison research can be used as a reference for selecting and designing the most useful e-learning instruction strategy.
