The Effects of Mathematics Learning Activity Using Open Approach with Badhams Questioning technique toward Mathematics Learning Achievement and Mathematics Problem Solving Ability of Prathomsuksa 1 Students
Abstract:
The purposes of this research were 1) to compare mathematics learning achieve-ment about "addition and subtraction of numbers with results and minuendnot more than 10" of Prathomsuksa 1 students after using an open approach with Badhams question technique with the criterion at 70 percent 2) to compare a mathematical problem solving ability about "addition and subtraction of numbers with results and minuendnot more than 10" of Prathomsuksa 1 students after using the open approach with Badhams question technique with the criterion at 70 percent. The samples for this research consisted of 35 Prathomsuksa 1 students in the first semester of the 2018 academic year at Anubanmuangmaichonburi School. The Participants were selected by the use of cluster random sampling. Instruments were: 1) lesson plans of mathe-matics using the open approach with Badhams question technique, 2) mathematics learning achievement tests about addition and subtraction of numbers with results and minuendnot more than 10. The difficulty score was between 0.39-0.67, and the item discrimination power was between 0.67-1.00, reliability 0.97 and 3) mathematical problem solving ability tests which resulted difficulty 0.69-0.70, discrimination 0.38-0.41, reliability 0.99. The statistics used in data analysis included Mean, Standard Deviation, and t-test for one sample. The findings were as follows: 1) The mathematical learning achievement about "addition and subtraction of numbers with results and minuend not more than 10" of Prathomsuksa 1 students after using the open approach with Badhams question technique was higher than the 70 percent criterion of .05 level of significance. 2) The mathematical problem solving ability about "addition and subtractionof numbers with results and minuendnot more than 10" of Prathomsuksa 1 students after using the open approach with Badhams question technique was higher than the 70 percent criterion. The level of significance was .05
