The introduction to Mr. Fadel's research clearly presents his thesis on multimedia based learning. Students using a well-designed combination of visual and text learn more than students who only use text. He is likely intentionally vague on this claim as factual evidence has historically been misused.
Namely, the cone of experience is hotly criticized in this article. Its original author, Dale, intended for it to be a visual metaphor depicting learning from the visual (bottom) to the abstract. It had nothing to do with percentage of retained information regarding these experiences. Instead it was taken by educational researchers to diminish the importance of learning through abstract means such as reading and hearing. As it turns out, this basic claim does a terrible job and explaining the complex nature of learners, their environment, and how material is presented. In other words, recent research has detailed the effectiveness of presented material based on how the brain works, how students learn best, and how much interplay exists between media and text in this material.
What factors of the brain must be considered when presenting any material? The first (as those in Heideman's minute sketch class are certainly aware) is the three types of memory and how they relate to actual learning. Before acquiring knowledge, learners must be sensorially alert. Obviously, information must actually be picked up by one of the five senses in order to enter working memory. This, in short, is why so many accidents occur while drivers are on their cell phones. Secondly, Working memory is, as Dr. Moore would say, the grappling process. It is creating, analyzing, and grouping schema. Finally, this information can be stored in long term memory in what we define as knowledge. Multimedia, should then seek to keep students alert by using all senses while helping to group and process information without distracting learners' attentions.
"How students learn", a topic general enough to describe human life; but in this article used describe three essential features to optimize learning. These are: Student preconceptions must be built on prior knowledge,
Fadel's final subsection presents the meat of the article in how it relates to our class: multimedia design in its visual and verbal modes. He presents 7 basic tips (one of which seems to completely contradict his message). One should always include text and visuals as retention increases when words are paired with media. Group words and pictures of the same idea in the same spatial region. This allows students minds to organize information better. Present similar ideas simultaneously rather then successively as students learn better this way (Does anyone have a hypothesis for why this may be true). Exclude any extraneous information that may be distracting. Positive benefits of this method are greater for low knowledge and high spatial learners. One heuristic that I'd like to analyze in further detail and get the group's opinion on is the Redundancy Principle. It states, "Students learn better when information is not represented in more than one modality-- redundancy interferes with learning." This seems to go against his conclusion with affirmatively says, "the most effective designs for learning adapt to include a variety of media, combinations of modalities, levels of interactivity, learner characteristics, and pedagogy based on a complex set of circumstances." Any thoughts???
This article details the complexity of the learning process that the "cone of ignoran...-I mean- learning" does not do justice. Using a variety of media in a succinct, flowing manner which is at harmony with students' natural learning process is certainly the take home message. The challenges of doing this are great. Our minds are constantly flooded with information, especially through the media. Teaching should not flood the mind, but allow our learning circuits to process and store information appropriately. In my opinion, effectively choosing what media to use in your classroom is a tremendous challenge. Suggestions or experience with well-tailored media would be lovely.
