The document summarizes an article about a Los Angeles charter school that implemented a blended learning model called BLAST. Under this model, students rotate between stations for direct instruction, independent learning on computers, and collaborative group work. At Tennenbaum Tech High School, which adopted this model, the average student performance improved from a 4th grade to 8th grade level after two semesters. The model personalizes learning more than traditional or solely computer-based methods. While an advocate, the author cautions that online assessments don't fully pinpoint weaknesses and teacher feedback is important for improvements. After observing blended learning models, the author believes it encourages independent lifelong learning and can be cost-effective by allowing smaller class sizes.
