In a previous article, ISM suggested that a fourth plank in the 21st Century School is “the individualization of the content and delivery of curriculum, which meets the needs and passions of the learner at the rate best suited to that learner, using blended learning as the means.” This was applied exclusively to middle and upper schools, leaving the question as to what part technology plays in the lower school. Subsequently, ISM Success Predictor No. 3 suggests that “interdisciplinary, flexible, and immersive curriculum/pedagogy” is intrinsic to 21st century teaching, and is applicable at all levels of the school.
