The Mind Institute has taken a spatial temporal approach with ST Math and the results have been outstanding for a broad range of learners in trials. This is an example of a math program that was universally-designed that reached the maximum amount of learners. Thank you Mind Institute!
"MIND Research Institute, an southern California nonprofit, developed an innovative way to teach math—and it works. Trials involving almost 60,000 students indicate that it typically doubles math gains.
They use visual games that all involve moving a penguin named Jiji across the screen. It’s all done without a word of instruction. The visual approach works for visual learners, students new to English, or students experiencing reading difficulties—in other words, it works for most kids.
MIND notes, that “Schools below 50% proficiency to begin with have averaged 15 to 20 point gains in proficiency within two years.” And remember, students in these trials just use the software twice a week for a bout 45 minutes."
