What is the difference between Task-Based Teaching and Task-Based Approach?

Task-Based Teaching应该就是Task-Based Approach.
Task-Based Approach是一种语言教学法, 学英语教学的人大概都知道吧~
"A task-based approach aims to provide learners with a natural context for language use. As learners work to complete a task, they have abundant opportunity to interact." (. Author: Diane Larsen-Freeman)
就我所知, Task-Based Approach 常会跟 Content- based instruction去做比较, 这两种有一些相似.
Task-Based Approach (任务导向教学法)主张提供学生使用语言的自然情境, 在合力完成任务的过程中, 会产笙许多互动的机会, 有助於语言的学习. 任务活动利用解决问题的形式, 让学生结合旧知识与新知识进行学习.
(刚好之前有修过英语教学概论的课, 希望对你有帮助^^)
