Teachers should design additional materials to meet the demand of the students in learning pronunciation. In our teaching context, our students seem to be still confused with the English sounds , especially the vowels as many of them do not exist in Vietnamese language. Therefore, we designed a set of material to help the 10th form students to solve the problem.

The set of material composes the followings:

1. a handbook for the 10th form students at upper-secondary school.

The handbook is aimed at recycling the new words they have met in their new textbook called Tieng Anh 10.

The content of the handbook consists of 20 pages on 20 English vowels: each page has all the new words in the textbook that contain the vowel that exists in English , the unit it appears, the phonetic symbol, the word meaning and three tasks designed for the students to practise the sounds in words and in sentences.

The pages are arranged in colour papers to classify 3 types of vowel sounds: short vowels, long vowels and diphthongs.

2.  A CDA recording our voices as reference to guide the students and help them self-practice .
