Determining the best way to layout and set up the physical space of a learning environment can be tricky. Great learning environments can differ wildly based on several factors, but the most important factors to consider are an educator's teaching style and the configuration of the physical space. Students may sit face-forward in a classroom while a teacher lectures from the front as a “Sage on Stage” engaging students with the curriculum. In other classrooms, the educator may allow the students to explore independently, while providing occasional advice, assistance, and correction. This method is commonly referred to as the “Guide on the Side” approach.
