Learning Outcomes of Mathematics in Solving Mixed Addition, Subtraction, Multiplication, and Division Problems Using the STAR Strategy and LT Cooperative Learning for Grade 2 Students

Abstract

The purposes of this research were: (1) to investigate the learning outcomes in Mathematics on solving mixed operation word problems—addition, subtraction, multiplication, and division—using the STAR strategy combined with LT cooperative learning for Grade 2 students; and (2) to examine students’ satisfaction with the Mathematics instruction employing the STAR strategy combined with LT cooperative learning. The sample consisted of 34 Grade 2 students from Class 2/2 at Ban Nai Mueang School, selected through cluster sampling with the classroom as the sampling unit. The research instruments included lesson plans, an achievement test, and a student satisfaction questionnaire. Data were analyzed using mean, standard deviation, percentage, and a t-test. The findings revealed that: (1) the students’ Mathematics learning outcomes achieved through the STAR strategy combined with LT cooperative learning were significantly higher than the 75 percent criterion at the .05 level; and (2) the students’ overall satisfaction with the Mathematics instruction using the STAR strategy combined with LT cooperative learning was at the highest level.
