The compare students’ learning achievement on the Mathematics skill on percentage by using the learning on normal teaching of Matthayomsuksa 1 students at Navamindarajudis Khungthepmahanakhon school

Abstract

          The purposes of the study were : 1) to create and to find the effectiveness of Mathematics skill on percentage of Matthayomsuksa 1 students to be effective according to the criteria 80/80, 2) to compare students’ learning achievement on the Mathematics skill on percentage of Matthayomsuksa 1 students by using the learning Mathematics on normal teaching, 3) to study satisfaction level of the students on the Mathematics skill on percentage. The samples consisted of 2 classes of Matthayomsuksa 1 students at Navamindarajudis Khungthepmahanakhon school. They were selected by cluster random sampling, which were Matthayomsuksa 1/3 and 1/9 students. The researcher randomly selected 2 classes, the first attempt was Matthayomsuksa 1/3 which was the experimental group taught by the learning Mathematics skill on percentage and the second attempt was Matthayomsuksa 1/9 which was the controlled group taught by normal teaching. The instruments used in this research were 1) Mathematics skill on percentage, 2) the learning plans of the Mathematics skill on percentage, 3) the learning plans of normal teaching, 4) an achievement test, and 5) a five-rating scale satisfaction questionnaire. The statistics employed in data analysis were percentage, mean, standard deviation and the test of independent sample.
          The results were found that 1) learning activity Mathematics skill on percentage of Matthayomsuksa 1 students had efficiency at 82.74/83.67 which was equal with the threshold. The researcher set the criteria at 80/80, 2) the learning achievement of the Mathematics skill on percentage of Matthayomsuksa 1 students which were taught by using the Mathematics skill on percentage of Matthayomsuksa 1 was significantly higher than the normal teaching at 0.5 and 3) Matthayom 1 students had the satisfaction towards studying the exercises in Mathematics of percent subject was at the highest level.
