Development of Computation Skill by Using, Explicit method Along with Solving Exercises for Mathayom Suksa 5 at Silaladwittaya School under the Administration of Si Sa Ket Province

Abstract

The purposes of this research were 1) to develop the students’ computational skills using the Explicit method, 2) to compare their skills with the criterion of Si Sa Ket Provincial Administration Organization, and 3) compare the skills before and after development. The samples were 22 Mathayom Suksa 5 students of Silaladwittaya School in the second semester of academic year 2014. The instruments were: 1) lesson plans, 2) computational skill development exercises, 3) a test, and 4) end-of-the-cycle test. The statistics for data analysis were mean, percentage, standard deviation and development scores.

The research findings were as follows:

1. Development of computation skill using the Explicit method with skill development exercises had 4 spiral circles, each with three phases: 1) planning, 2) operation and observation, and 3) feedback. The Explicit Method had six phases, namely: 1) pre-test, review and check homework, 2) presentation, 3) practice, 4) feedback and improvement, 5) free practice, and 6) review of practice.
2. 77.27 % of the students passed the set criterion of 70 %.
3. The students’ skill after the development was 24.30 % higher than before the operation, with the average development of 58.04 %.
