What are the best possible steps to train our undergraduates to be fluent English speakers?

First Steep Is To Give them Chance to speak ... And Try To Understand Them Secondly Is To Make belive In Them Self's And Try to clean The eareias For them Laste and not liste Is To communicate With them As well as you can Then You'll have a chance To teach Them The real English languge 

To accomplish this task, first and foremost, the teacher should have a good understanding of the learning patterns of each and every one of his/her students. Some students tend to learn faster through visual stimulation, while others tend to prefer audio stimulation. Wtih this understanding, the teacher can identify how best to make learning interesting for each one of his/her students, either visually through movies, short dramas, and other graphic/visual methods, or through audio methods like listening to audio books, music, and other similar methods. Once this knowledge is established, the teacher can implement this methods and also encourage more conversation among the students in English language, so as to improve their English speaking proficiency.

ASK THE STUDENTS TO PRACTICE WITH VOCABULARY WORDS.

TRAIN THEM TO USE GAP FILLERS LIKE UM., WELL., ETC

EMPHASIS THEM THE USAGE OF LINKING WORDS SUCH AS BECAUSE, ALTHOUGH, ETC

TEACH THEM HOW TO THINK IN ENGLISH.

Let them speak in english as much as possible

the 2 best ways which i have experienced myself for improving the speaking skill is to watch english documentries, videos etc of our own interest and to speak english with our mates and younger ones.. it not only improve our speaking style.. but also improves proper use of grammar and vocabulary.. and another advantage is our self evaluation during speaking..
