การพัฒนากิจกรรมการเรียนรู้คณิตศาสตร์เพื่อส่งเสริมความรู้สึกเชิงจำนวนสำหรับนักเรียนชั้นประถมศึกษา

Abstract

The purposes of this research were to develop of Mathematics Learning Activities to Promote Number Sense for Primary School following the standard criteria 70/70. To compare the result of pretest and post-test activity by using Mathematics Learning Activities to Promote Number Sense for Primary School. The sample of this research consisted 42 grade 4-6 students, during the second semester in the academic year 2020 at Ban Cridonchai School Fang district, Chiang Mai province. Which was chose by cluster random sampling. The instruments using collected by Mathematics Learning Activities to Promote Number Sense 6 lessons and lessons plan 18 plans. Using final examination 30 points and subjective test 7 points and was analyzed by mean and One-way repeated measure MANOVA

The research findings were as follow: 1) The overall of Mathematics Learning Activities to Promote Number Sense were 26.32 (E.I.), 2) All of Mathematics Learning Activities to Promote Number Sense were qualifies. The average of E1 is 88.91 and E2 is 56.94, and 3 ) The average score of pre-test and post-test of students who studies by collected Mathematics Learning Activities to Promote Number Sense. The achievement of posttest average were X̅ = 21.07, and standard deviation S.D. were 5.00 and pretest average were X̅ = 15.38, standard deviation S.D. were 6.37. The students learning progress average were X̅ = 5.69. The results of One-way repeated measure MANOVA showed that. To compare the result of pre-post test by using Mathematics Learning Activities to Promote Number Sense for Primary School is higher than before learning at the .01 level of significance.
