A study of Academic Achievement on Quadratic Polynomial Factorization by Using Mathematics Skill Practice for Mathayomsuksa 2

Abstract

The purposes of this research were 1) to compare mathematics learning achievement on the factorization of a quadratic polynomial of mathayomsuksa 2 students by using mathematics skill practice, and 2) to compare mathematics learning achievement on the factorization of the quadratic polynomial of mathayomsuksa 2 students by using mathematics skill practice with 70% criterion. The sample group used in this research was 36 mathayomsuksa 2/4 students who were studying in the academic year 2019, Suankularb Wittayalai School (Chiraprawat), Mueng Nakhon Sawan District, Nakhon Sawan Province, which is obtained by simple random sampling. The research instruments comprised 4 mathematics skill practices in the factorization of the quadratic polynomial topic and the factorization of quadratic polynomial achievement test. The results of this research showed that 1) the students’ learning achievement on the factorization of quadratic polynomial after using mathematics skill practice was higher than before using mathematics skill practice with a statistically significant difference at the level of .05. 2) Mathayomsuksa 2 students’ learning achievement on the factorization of quadratic polynomial after using mathematics skill practice achieved the criteria of 70 percent.
