Development of Learning Achievement and Capabilities of Solving Math Word Problems on Volume Measurement for Grade 3 Students Using Nano Learning and Bar Model Technique Development of Learning Achievement and Capabilities of Solving Math Word Problems on Volume Measurement for Grade 3 Students Using Nano Learning and Bar Model Technique

Abstract

The purposes of this research were to 1) compare students' learning achievement before and after learning by using Nano Learning and Bar Model Technique, 2) compare students' capabilities of solving Math word problems after learning by using Nano Learning and Bar Model Technique; and 3) study the grade 3 students’ satisfaction with learning management by using Nano Learning and Bar Model Technique. This research is experimental research. The sample was selected from 41 grade 3/3 students at Prakhonchaiwittaya School, Prakhonchai District, Buriram Province, under The Office of Buriram Primary Educational Service Area 2 in the second semester of the academic year 2024 obtained by using cluster random sampling method. The research instruments consisted of 1) lesson plans, 2) achievement test in multiple choice form, 3) capabilities of solving Math word problems test, and 4) satisfaction questionnaire. Data analysis were used basic statistics and testing hypotheses by using Dependent Samples t-test and One Sample t-test.

         The findings showed that: 1) The grade 3 students’ learning achievement which was taught by the learning management on volume measurement by using Nano Learning and Bar Model Technique was significantly higher than before learning at statistical level of .05 statistical level or 88.90 percent. 2) The grade 3 students’ capabilities of solving Math word problems which were taught by the learning management on volume measurement by using Nano Learning and Bar Model Technique were higher than the criteria of 70 percent with statistical significance at the .05. The percentage of the scores was 79.79. 3) The grade 3 students’ satisfaction which was taught by the learning management on volume measurement by using Nano Learning and Bar Model Technique in all aspects was in the good level (  = 4.37, S.D.=0.24). The most satisfaction of the content is students have a feeling of fun in learning (  = 4.73, S.D.=0.55)
