The Learning Management Based on the Concept of UPSC Model to Develop Mathematics Problem Solving Abilities for Grade 9 Student in The Chiangmai Christian School

Abstract

              The objectives of this research were 1) to create the lesson plan based on the concept of UPSC Model about surface area and volume for grade 9 students. 2) to study abilities of mathematics problem solving in surface area and volume based on the concept of UPSC Model for grade 9 student. The sample is 36 students in 1 classroom of grade 9 student in The Chiang Mai Christian School used by cluster sampling. Research instruments were 1) the lesson plan based on the concept of UPSC Model in surface area and volume 2) propriety assessment form lesson plan and 3) the 6 multiple choice tests in abilities of mathematics problem solving in surface area and volume and rubric scoring criteria. Data were analyzed using percentage, mean, standard deviation, coefficient of variation, t-test (Paired Two Sample for Means) and Z-test (One Sample test for Proportion).

              The results revealed that 1) the lesson plan based on the concept of UPSC Model in surface area and volume with 3 content and 9 lesson plan the result in the propriety assessment of the lesson plan about content, learning activity, learning media, evaluation and lesson plan model, are suitable at the highest level and 2) after learning based on the concept of UPSC Model the result of abilities of mathematics problem solving the score of post-test is more than the pre-test with difference of 38.53, the coefficient of variation of post-test is less than the pre-test testing, use as statistical test by t-test tor mean of students’ abilities of mathematics problem solving after using the lesson plan was higher than score before using the lesson plan at the level of 0.05 significance and Z-test, more than 60% of all students have abilities of mathematics problem solving at a high level with significance at the 0.05.
