I'm a Master's student and I'm currently teaching the Nepali language to Belgian couples and it has been a very exciting journey for both parties. Each week we set out the goal and take it from there. Sometimes we take a pause so that it flows naturally.
In addition to language, I also provide the cultural context of the used words and phrases and the nuances of them. This helps students to understand the context of when and how to use the learned materials. Reference can be provided upon request.
Depends upon the motivation of the student and what area of linguistic they are interested in. It gets easier once the intentions are out because each lesson is tailored to fit students' motivation in learning the language.
