Recent advancements in multimedia systems to integrate text, audio, graphics, and video have created a new interest in using instructional strategies in a multimedia-based learning environment. In this light, this study explores the effect of two types of visualisations (static and animated) and advance organisers (descriptive and question) on EFL learners ’ reading comprehension in a multimedia context. To this end, a software program with four computer-based modules was designed to show texts with four instructional formats- texts with static visual embedded descriptive advance organisers, texts with static visual embedded question advance organisers, texts with animation embedded descriptive advance organisers, and texts with animation embedded question advance organisers.

Once the EFL learners interacted with their respective instructional materials, they then took a reading comprehension test. The results revealed that the question type of advance organiser was mor
