Mostly the sort of issues that Zorro and Nahadef talked about in the English teachers thread, such as teachers being unable to deviate from a specific curriculum that the school boards want to be taught as well as how they should teach it.
That is undergoing change. I can't recall specifics, but if you are an ALT from a dispatch company, your employer is not the school, and they can't dictate what/how you teach. You do what your company says. Even so, it will depend a lot on the relationship between your employer and the board of education or school. ALT business here is a terrible mess.
I've also read in a few different books and articles online about how wasteful the investment in English education is since it doesn't teach the students nearly enough to use English very practically.
True. What's your point, though?
I've seen many videos online created by entire classes of Japanese students who want their English classes to teach them more effectively and leave them with skills that will help them in the long run.
What research I've done (no videos, but journal articles) shows that students want to be able to converse better, but their intention is not to have any long-term skills for work purposes. They merely want to chat with foreign friends more than anything else. Keep that in mind.
The problem begins with the college entrance exam system. Teachers are obligated to teach students to the exam, especially during the last 2 years of high school. Since the vast majority of such exams have no speaking component (and are unlikely to in any foreseeable future), kids are taught dreary grammar-translation (useless in the long run), how to unscramble sentences (a waste of time), and how to guess at multiple choice tests (like that helps someone with a conversation). End result? Kids leave with 6 years of English education, where only the first 2-3 years were of any useful merit (to instruct them in the basics of grammar), and the inability to get beyond "Hi, how are you?"
I'd like to see the videos you mentioned.
By the way, I feel like I may have gotten the wrong idea about eikawa -- is it just a different school setting, like an honors/alternative class, or is it more like an extracurricular class that people pursue on their own?
You're way wrong if you think it's for honors kids. Eikaiwa itself means "English conversation". The word has evolved into meaning the business, too. It is a company operation where classes are arranged to help people learn how to use the spoken word, for tourist activities, daily life, work (sometimes), or just about anything else. Keep in mind that it is strongly considered a business operation by its managers (who often/usually have no training or background in teaching). The object for them is to make money, even if that means scamming clients with lesson tickets that are non-refundable (one reason NOVA went down), or putting people in classes with such mixed abilities that it's impossible to teach sensibly, or that teachers may have to attend mixer parties to show themselves off and cajole students and prospective students into staying/joining. Kids and adults take the classes. Kids are often forced to do it because parents think it will benefit them in public school. They may start as young as 1 year old! Adults take it for 2 reasons: most people because it's a hobby or even a social function (to get out of the house and meet people), or because their employer heavily requires it as a means to pass TOEIC with higher scores for promotions or overseas transfer. The latter point (about businessmen) is something I've been researching a while now. Most people who take an eikaiwa class are not there for serious improvement in their language ability and/or they are deluding themselves into thinking it will help with a mere 1 class per week and no homework and no inclination to self-study.
