Hello Jin. Great post. I like that you have indicated that you cut out the advertisements in the game to make the video more effective. I relate this assertion to the coherence principle which states that people learn better when extraneous materials are excluded. The advertisements in this case are extraneous materials and thus cutting them out reduces extraneous processing and keep the video simple. Besides, I like that you have indicated that you did not include your voice which would otherwise affect the learners thinking. This assertion further relates to the coherence principle which supports exclusion of extraneous sounds. Nonetheless, I wonder if you would have considered including your voice in the interactive video to replace texts. Inclusion of the voice relates to the modality principle which asserts that people learn better from graphics and narration than from graphics and text (Mayer, 2009). This manages essential processing.
