Abstract

The objectives of this research were 1) to develop the pronunciation of English final consonants (/s/, /z/, /ed/) using cooperative learning with STAD technique of Mathayom 4 students to reach above the 70 percent or more threshold, and 2) to compare the learning achievement of English language course in the pronunciation of English final consonants (/s/, /z/, /ed/) before and after using cooperative learning with STAD technique of Mathayom 4 students. The sample group was thirty-eight of Mathayom 4/2 students who studied Basic English Language Course 1 (EN31101), Semester 1, Academic Year 2020, Krabyai Vongkusolkit Phitthayakhom School, Ban Pong, Ratchaburi Province, selected by Purposive Sampling.

The statistics used for data analysis were mean, standard deviation, and t-test.
