The aim of this study is to 1) study the ability to create one variable linear equations based on word problems among Mathayomsuksa One students by the Bar model method; 2) to investigate the efficiency of teaching the topic of creating one variable linear equations from word problems using the Bar model method with a 70/70 criteria; and 3) to study the satisfaction of students regarding this teaching method. The population of this study included one class of thirty students in Mathayomsuksa One, in the first semester of academic year at 2018, Wat Nong Yai School, Bangkok. The methodology employed Cluster Random Sampling from five classes which included one hundred and fifty four students with a combination ability stays. The findings found that: 1) the sample group which used the teaching technique to create one variable linear equation from word problems using the Bar model method was capable of creating these equations at a level higher than the standard and sixty per cent of all students and the significance of these statistics was .05; 2) the efficiency of teaching how to create one variable linear equations from word problems using the Bar model method of this students was E1/E2 = 73.75/62.83, and 3) the sample group of students were satisfied with these teaching technique at a high level.
