Introduction Blended instruction is an instructional approach that combines the benefits of online and classroom instruction. It initially originated from efforts to improve distance learning environments. In particular, it was aimed at improving online learning environments where learners can be easily disoriented due to a lack of communication or direct guidance (Marsh II et al., 2004; Rossett, et al., 2003). Regarding the learning environment, Savery and Duffy (1995) argued that there are two factors that affect learners' attitudes toward learning. One is the familiarity with the instructional medium and the other is the ability to make something meaningful out of the material presented. According to Savery and Duffy (1995), when comparable content is presented to learners, both on-screen and in printed text, the information presented on screen is mentally more demanding than the printed text. Learners find it difficult to make connections between information presented and its value due to the unfamiliarity of the presentation mode.
