Tom Vander Ark :" ...I believe personalization has the best potential to boost achievement. Accurately targeting learning level and diagnosing any learning gaps are probably the two most important factors to improved learning for most students. However, I think of personalization broadly and believe beneficial factors also include a positive school culture, student voice, sustained relationships, and a degree of agency over at least a portion of the course of study.
As the toolset improves, personalization will not only include level, rate, time, and location but modality. Comprehensive learner profiles will soon lead to improved understanding of student motivation and, I believe, will lead to the development of customized playlists that will significantly improve learning productivity."
Tom discusses the importance of maintaining high expectations when grouping students - emphasizing performance grouping rather than "ability" grouping.
