contribution to the comprehension of the learning processes. Knowles himself mentions that andragogy is a "model of assumptions about learning or a conceptual framework that serves as a basis for an emergent theory." There appears to be a lack of research on whether this framework of teaching and learning principles is more relevant to adult learners or if it is just a set of good practices that could be used for both children and adult learners. The way adults learn is different from the pedagogical approach used to foster learning in K-12 settings. These learning differences are key and can be used to show that the six characteristics/principles of andragogy remain applicable when designing teaching and learning materials, in English as a Foreign Language (EFL), for example.
