      foundthat learners who received a multimedia lesson withanimation and audio narration alone performed onaverage 79% better than learners who received alesson containing animations, audio, and redundanttext.

      This makes sense. For my own students, I find that they retain information better if I have them watch a video and take notes independently, versus me showing a video to the whole class and discusing it or taking notes. The visuals, audio, and re-explaining of a concept tie into this research

      Redun-dancy refers to learning inefficiencies that resultwhen we provide learners with too much information

      The context of how redundancy is used here is interesting to me. I typically think of redundancy in terms of repetition.

      As part of the analysis phase,you should determine whether your course’s targetaudience includes learners with no prior knowledgeof the subject matter, with some intermediate knowl-edge, or perhaps even with advanced expertise. Inaddition, you should analyze your instructional objec-tives to determine whether they are simple or com-plex. The guidelines of cognitive load theory must beadapted based on the complexity of the content andon the experience of the learners

      I feel like this is the backbone of instruction. We always want to start with the concept of what do my students know/not know, what is their ability level, how do I need to prepare the materials/text/tools so that they can independently access them?

      ability to process andretain information diminishe

      I wonder if this "magic number" is also true for students with diminished working memory or cognition?

      According to this psychological prin-ciple, working memory can only process sevenchunks of information at any given time, plus orminus two items

      This is helpful to know. When I took AP US History in high school, my teacher always told us to only put up to 7 pieces of information on a notecard. He was defintely using this research!
