Planned learning activities and teaching methods | Lectures for learning the theory and fundamentals in materials Explaining with specific examples different aspects in materials and solve specific problems Demonstration of actual materials (Silicon mono-crystals, poly-crystalline metal alloys etc) Frequent short quizzes (about 8) on previous class lecture in order to enforce the “every day” studying and prepare the students to readily attend the next class lecture Tutorials, where the students ask further questions on the lectures for better comprehension Frequent reviews and discussions | ||||||||||
