Sangetsu, what type of school are you in? Your view on no Japanese at all doesn't jive with mine. Kids NEED to understand grammar. Younger kids can certainly internalise it WITH enough exposure. However, for older students, teenagers, like mine, internalising grammar rules is almost as difficult as it is for adults. Just as I need grammar explanation of Japanese grammar in English, my students need explanation of English grammar in Japanese. And if a JTE isn't there, that means I have to supply it.
