Secondary schools have a unique relationship with content coverage, in part due to policies, standards, and exam requirements. Has it ever bothered you that not one cadre of standards writers ever determined whether all that content could reasonably fit into the regular school day and year? It bothered us. So we systematically figured out exactly how much content can be covered in the average Grades 8-12 classroom if desirable instructional practices (e.g. PBL, inquiry-based learning, etc.) were employed (all the way down to 20-minute increments, which is why we can customize pacing guides for every school schedule). Read on to gain our insights into content-per-unit-time as well as why we need to change our relationship with content altogether.
