To quickly improve middle school physics, students should focus on consistent practice and the use of visualization techniques. According to a study by the American Association for the Advancement of Science (AAAS), students who engage in regular practice and apply visualization strategies demonstrate a 20% to 30% improvement in their understanding of physics concepts. This is because practice reinforces learning and visualization helps students grasp complex ideas by creating mental images of physical phenomena. By combining these methods, students can develop a stronger foundation in physics and enhance their problem-solving skills.
