My teaching goal is providing a meaningful teaching and learning and a key belief. I am a proponent of requiring students to engage in extensive written, as well as spoken, discourse. There are some methods and strategies to implement it. For instance, online chat (forum), or quick responses like picture prompt/ provocative picture to a central question, have often helped to begin or facilitate a discussion. From these techniques, students free to explore physical environment as well as to solve problem and create new knowledge.
