I have felt interested in PBL. I think this method can help Thai students think critically and analytically. They can think by themselves. And also they can find their interesting topics. They have to brainstorm their ideas with one another so that they can be sucessful with the aimed project. I have been an English instructor of private school. During this time, I have tried to enlarge new knowledge on English teaching methodology so that I will use it ith my students. If you have any advice about PBL, please inform me. I will appreciate so much for your kindness in advance.
