Abstract: Learning management focused on students to remember content and to remember how to follow the example, students do not succeed in solving problems as they should. It does not promote the thinking process of students. One of the most popular ways to train a student to solve a problem by emphasizing the thinking process of the students is to train the students with problem solving skills based on the concept of the Polya. By this reason, the purpose of this study were 1) to study the students’ learning achievement on polynomial factorization after using the exercises of problem solving with Polya’s concept for Grade-9 students, and 2) to compare the learning achievement on polynomial factorization for Grade-9 students between before and after learning using the exercises of problem solving with Polya’s concept. Using simple random sampling, the samples of this study were 15 Grade-9 students at Thetsaban 2 Wat Sawang Khongkha School, Muang district, Kalasin province studying in the first semester of the academic year 2018. Instruments were 8 lesson plans using problem solving process with Polya’s concept on polynomial factorization and the test of knowledge regarding polynomial factorization. Data were analyzed using percentage, mean, standard deviation and t-test. The results of the study were as follows: 1) the percentage of students’ learning outcome was 83.65 ( = 16.73, S.D. = 1.39), and 2) post-test scores after the use of problems solving exercise with Polya’s concept regarding polynomial factorization was significantly higher than pre-test scores at the level of confidence of 0.05.
