The document discusses different frameworks for understanding the relationship between approaches, methods, and techniques in language teaching. It describes Edward Anthony's original framework from 1965 that defined approach as assumptions about language and learning, method as how theory is implemented in teaching particular skills, and technique as classroom procedures. However, this framework was criticized for being too simplistic. Richards and Rodgers later proposed defining approach as theoretical assumptions, design as how theory relates to materials and activities, and procedure as classroom techniques, but their framework was also found to have redundancies and overlaps between levels. The document analyzes different perspectives on categorizing the elements of language instructional design.
