Best practices are teaching strategies that are progressive, developmentally appropriate, research-based, and teachable. They include teaching a balanced curriculum through an enriched environment that promotes active learning and brain development, teaching an integrated curriculum where students make connections across disciplines and take ownership of their learning, and differentiating instruction to accommodate individual student needs, strengths, and learning styles. While some research shows that certain instructional techniques like Whole Brain Teaching have led to improved test scores, barriers remain to fully implementing practices that identify and reward the most effective teachers.
