An overall thinking process and links between current subject and future application; Problem Solving Skills. From problems in quizzes to daily life and science news. Thinking process for science over all. The general way of communicating with teachers and students at school; Problem solving skills and math skills. Approaching with proper concept and use math as the language in science.; Examples in daily life and applications. My teaching philosophy is more to build a proper thinking process than simple problem solving. I will first discuss current concepts known and start from there by asking questions and thoughts.
