You get what you pay for. Bodhi Tree's adult languages classes are affordable and scheduled conveniently for working people. They are not university classes and don't pretend to be. They're not even high school classes. They're "community" classes which attract learners with a very wide variety of abilities, backgrounds, and motivations. The public assumption that being a native speaker of a language somehow qualifies a person to teach that language seems to rule here.
Before a scheduled sojourn in a foreign land, I was delighted to find an available class in the language of that land, and cheerfully signed up. I did the homework and attended every session. My teacher was not a credentialed language instructor but this person was generally punctual, knowledgeable and sincere. The textbook was good. My overall disappointing results were not due to any lack of good will on the part of students or teacher. The issue was that because the instructors are not trained in how to handle mixed-level classes, my teacher wasted a great deal of time (my time) in trying to cater to those unprepared (didn't do the homework) or those who have no idea how to learn a language (most Americans).
For example, one woman student, in her thirties, leapt up from her seat at least three times during every class to answer voice calls, and texted constantly throughout. Having missed the instruction, she would ask the teacher to repeat the point, which he politely did. Another older man apparently had never studied a language before (perhaps had never studied anything before). He filled the class hour with random questions about basic grammar (what is a noun? what do you mean, noun?) history, and politics -- all of which the teacher politely answered, sometimes at length.
Due to the teacher's lack of training in mixed-level classroom management, the pace of instruction was extremely slow and disorderly. In eight weeks I learned very little. I would not go back. Still, with so much variation among individual teachers and the possibility of a better mix of adult students, your mileage may vary. Bodhi tree is the only place in Portland to get formal instruction in Mongolian, for example -- and it's affordable. By all means give it a try, but I'd recommend to keep expectations low. read more
