The effect of learning activities using open-ended questions in problem-based learning on mathematics concept

Abstract

               The objectives of this research are 1) to compare the mathematical concepts of students before and after used open-ended questions in problem based learning management in congruence   and parallel  2) to compare the mathematical concepts of students used open-ended questions in problem based learning management in congruence   and parallel with the criteria of 70 percent. The samples were Grade 8 Students at Ban Na "Nayokpittayakorn" school , Secondary Educational Service Area Office 7 (SESAO) , Office of the Basic Education Commission Ministry of Education   41 students from the second semester of the academic in 2019 were selected by Multi-Stage Sampling. The research instruments consisted of 1) the learning management plan by using open - ended questions in problem - based learning management 3) the mathematics learning concepts  test on congruence and parallel lines with the Reliability value 0.73. The statistics used for data analysis is mean ,the standard deviation t–test  and t–test  for t-test independent.

            The results of the research showed that 1) Mathematics learning concepts posttest of students using open - ended questions in problem based learning in congruence and parallel higher than that pretest at the 0.05 level. And 2) Mathematics learning concepts of students using open - ended questions in problem based learning in congruence and parallel lines were higher than                    the criteria (passed the criteria of 70 percent) with statistical significant difference at the 0.05 level.
