Educational technology aims to improve the teaching and learning process in several key ways: it thoroughly analyzes teaching and develops theories to improve education quality; it establishes better relationships between teaching and learning by analyzing the process; and it draws from various fields like psychology and engineering to improve learning. Educational technology also helps enhance education goals over time, train teachers for new curricula and materials, develop curricula and teaching materials tailored to learners, evolve effective teaching strategies using audiovisual aids, and identify community needs to improve education overall.
