My opinion -2

Quizlet

It is very useful tools to make student encourage strong vocabulary ability.
It is very helpful for teacher that can make flashcard easily. most attractive tool is "searching image" automatically.
when they learn the words, it is very important that listening and reading are included.
The spelling of words would be next. What i attract the most is that t is available to study with listening , reading and writing at the same time.
Before the class, I will let student  look through key words at home.
During the class, i I will try to check students' previous learning in order to remind key words
After the class, I will let them review  so that they can keep them in mind

It is like take home on-line lesson.
It is really helpful for developing their ability and understanding the lesson easily.
