First, I will talk about the Teach and Learn Approach.
・Students can understand the meaning of the words easily.
・They will be able to review the words easily when they forget them.
・Students can be bored with learning because it is a little monotonous.
・Students may forget the words easily. Sometimes the memories are transient.
Second, I will talk about the Learning through Input Approach.
・Students can memorize the words well because they can imagine a concrete situation.
・Students can concentrate on the learning because they can enjoy the theme or topic itself.
・It is a little difficult to understand sepecially for the students who not good at English.
・When students learn some words on the textbook, the words don't often have connection. So it is a little difficult to use this method when students learn with the textbook.
Lastly as a junior high school English teacher I would favor a Hybrid. Two methods have each effective points, but I think that it isn't an ideal way that teach by the same method every time. So I think that keeping their balance is also important.
