Final answer:
Justin recommends theory vs practice to emphasize practical skills, helping to integrate theoretical knowledge with real-world application for deeper understanding.
Step-by-step explanation:
Justin recommends theory vs practice time because it is a helpful practice that integrates new knowledge into one's brain by validating behavior in known contexts. The option that best fits this purpose is B) To emphasize practical skills. By applying new tools to familiar situations to build trust and competence, students can ground their theoretical understanding in practical application. This process is much like studying sociology, where one learns to apply statistics in practical situations, or geography, where students learn the skills of thinking spatially and solving problems. It helps students avoid focusing solely on memorization or equation-hunting, thereby encouraging a deeper conceptual understanding that promotes long- lasting learning and development of critical thinking skills.
