Creaza is used in a wide range of subjects and in all grade levels. Here’s an example of how a Swedish high school teacher has used Creaza Mindomo to flip his classroom in order to teach math.
Johan Cheander from Perstorps Gymnasium, one of Sweden’s top high schools, teaches math among other subjects. He uses flipped classroom in several of his classes, enabling his students to go through the subject matter prior to having the lesson.
On his blog he posts presentations made with Creaza Mindomo, along with movies showing the calculations, connections and explanations.
