What are the differences between teaching approach, teaching method, teaching technique and teaching strategies?

The teacher uses different approaches, methods and techniques to teach to his/her students. So, we have to know the different between each concept. An approach is a set of specific theories about the nature of language and language learning. A method is an orderly plan for the presentation of language material based on the selected approach. And a technique is an implementation strategy or trick used to accomplish and immediate objective. It actually takes place in the classroom. In other words, a way of presenting language to students. When we talk about an approach, you talk about something general, you are focus on the personal way of philosophy. It’s involve everything referring to teach. When we talk about a method, you talk about something more specific because is the way the teacher apply his/her philoshopy when he/she is teaching. And when we talk about a technique, you have to know that are all the tools that you’re going to use in your class. You have to take account that each class’ group is unique and you should take account all the environment in every single class.
