A Study of Proficiency in Multiplying Decimals Among Fifth-Grade Students Through Collaborative Learning Management with a Multiplication Simulation Model

Abstract

             The objective of this research is to examine the proficiency in multiplying decimals for fifth-grade students who have undergone collaborative learning management with a spatial simulation model, aiming to achieve a minimum score of 70%. The research sample is of 18 students from Class 5/2 at Samkhompattana School in Namon District, Kalasin Province, during the first semester of the 2026 academic year. The sample was randomly selected. The research tools used include 1) collaborative learning management plan with a spatial simulation model, 2) a test measuring proficiency in multiplying decimals, and 3) a post-teaching record by the teacher. The statistics used for data analysis include percentages, mean values, and standard deviations.

             The research results reveal that students in the sample group showed an improvement in proficiency scores in multiplying decimals after undergoing collaborative learning management with a spatial simulation model. In the first practical circuit, 10 students met the criterion of 70%, accounting for 55.55%, while 8 students did not meet the criterion, representing 44.44%. In the second practical circuit, 4 students met the 70% criterion, making up 50%, and 4 students did not meet the criterion, also representing 50%. In the third practical circuit, 4 students met the 70% criterion, accounting for 100%, and no students failed to meet the criterion, representing 0%. It can be observed that the proficiency scores in multiplying decimals for the target group of students improved in each practical circuit round.
