2. ABSTRACT
Speaking is a very important skill for language learning focused on using English to
communicate. Games can motivate the students to speak more fluently, reduce
students’ anxiety and resulting positive attitude towards learning language also. This
study aimed to (1) study the efficiency of developing speaking skill by using game, (2)
study the effectiveness indexes of using games to improve speaking skill, (3) compare
pre and post test of English speaking skill by using speaking developed activity by using
games, (4) study students’ learning behavior by using competition game between
reinforced and non-reinforced with the reward. The sample was Pratomsuksa 4/1 of 41
people by means of purposive sampling. The instruments used in this experiment were
learning instruments (4 lesson plans to improve speaking skill by using games) and
compilation data instruments (pre–post tests, Evaluation of reinforced and non-
reinforced with the reward’s behavior).
The results of this study reveal that (1) efficiency of developing speaking skill by using
games of Pratomsuksa 4 students was lower than the criterion, (2) effectiveness index
of using the games to improve speaking skill was 0.3213, or 32.13 %, (3) compare
English speaking pre and post scores were significantly higher than pre-test scores of
the student at the 0.05 level, (4) The students’ behavior that arising from reinforced and
non-reinforced with the rewards reveals that reinforced with the rewards was 74.39 %
and non-reinforced with the rewards was 23.17 %.
The results of improving speaking skill by using games has achieved goal, the students
have a speaking development and can speak English effectively.
