Effects of Inquiry Approach Learning Management with KWDL Problem Solving Package in the Topic of Interest and Value of Money for the 11th Grade Students

Abstract

The aims of this research were 1) to study the effectiveness index of inquiry approach learning management with KWDL problem solving, 2) to compare the mathematic problem-solving performance between before and after learning, and 3) to study the students’ satisfaction on inquiry approach learning management with KWDL problem solving package. The research sample consisted of 44 students in grade 11 (room number 9) attending to Sarakhampittayakhom school in the second semester of academic year 2022. The instruments used in this research were 8 lesson plans - KWDL problem solving package created by the researcher, the 10 items mathematics problem solving ability test, and 15 items rating scale questionnaires on learning satisfaction with inquiry approach learning management with KWDL problem solving. The statistical methods employed for data analysis were percentage, mean, standard deviation, and Wilcoxon signed rank test. The results of the research were as follows: 1) the plans had the effectiveness index of 0.5983, which meant that students had 59.83 percent of learning progressiveness, 2) the students’s Mathematics problem solving ability scores were higher than before learning at the .05 level of significance, and  3) the satisfactory of students on learning at highest level (= 4.44, S.D. = 0.75).
