The Development of Mathematical Solving Problem Abilities in Probability by Using Nht Moddel Together With Kwdl Technique for Matthayomsuksa 3 Students

Abstract

           The purposes of this research were 1) to compare the before and after of the learning achievement in mathematics by using NHT model together with KWDL technique for Probability. 2) to compare the criteria 60% and the after of the learning achievement in mathematics by using NHT model together with KWDL technique for Probability. 3) to compare the criteria 60% and the after of mathematical solving problem abilities by using NHT model together with KWDL technique for Probability. 4) to study the satisfaction of students on mathematics learning by using NHT model together with KWDL technique for Probability. The sample consisted of 18 matthayomsuksa 3 students, second semester, academic year 2023, from Nongpruepittayakom school, Kanchanaburi Province, which were obtained by cluster random sampling. The instrument of this research consisted of 1) the lesson plans in mathematics 2) the achievement test in mathematics for Probability 3) the mathematics problem solving ability test for Probability 4) the satisfaction survey form to mathematics learning. The statistics in the analysis were mean, standard deviation, t-test for dependent sample and t-test for one sample. The results of the research were : 1) the after of the learning achievement in mathematics by using NHT model together with KWDL technique for Probability higher than the before studying at statistical significance level of .05 2) the after of the learning achievement in mathematics by using NHT model together with KWDL technique for Probability higher than the specified criteria 60% at statistical significance level of .05 3) the after of the mathematics problem solving abilities by using NHT model together with KWDL technique for Probability higher than the specified criteria 60% at statistical significance level of .05 4) the satisfaction on mathematics learning of students by using NHT model together with KWDL technique for Probability are at a high level.
