what i've always said to my students to have a better chance of scoring high in toefl-speaking is to start thinking in english(for esl students)..and the question that is always thrown back at me is "HOW?".....i told my students to practice speaking in front of the mirror, i also recommended memorizing although i know it's not a good idea...but what hit me is that when i showed a picture to mys student and told him to describe it in 5 sentences, he did it with ease...so i stuck to it...everyday, i show him different pictures and ask him to describe the picture in complete sentences with the words the come to his mind first...although at first when added "the words that comes to his mind first", it was a little bit hard for him, but as time went by he became acuustomed to it....nevertheless, i think this may not be applicable to all students, but it's worth giving a try.....gud day....
