Abstract

This study aimed to determine the application of the problem-based learning approach to improve the mathematics problem solving skills of the fifth grade students of SDN Susukan 04. The research was conducted at SDN Susukan 04. The method used in this study was the Plomp development model which consisted of three stages: (1) Preliminary Research; (2) Prototyping Phase; (3) Assessment Phase. The subjects in this study were students of class V SDN Susukan 04. The type of data in this study was quantitative. This quantitative data was obtained from the validation result score, the score of 10 students on the observation sheet and the learning material mastery test (TPBA) score. The validation phase of teaching materials developed with the Problem-based Learning approach and validation of the problem-solving ability test. Seeing what happened to students, it was necessary to strive the development of the teaching materials to improve problem-solving abilities in learning Mathematics with the Problem-based Learning approach, as the importance of solving abilities learning problems in teaching success. The test for the difference in the problem-solving ability test of the experimental  class and the control class could be seen from the mean of the experimental class = 78.70> the mean of the control class = 64.76. So it can be concluded that the average problem-solving ability of the experimental class students were higher than the problem solving ability of control class students .

Abstract

This research aims to determine the effect of the Student Facilitator And Explaining learning model assisted by Dopesen media on the conceptual understanding ability of fifth grade elementary school students. The type of research used is Quasi Experimental Design with Nonequivalent Control Group Design. The population in this study were all students of Ungaran 02 Elementary School. The sample used in this study was non-probability sampling with purposive sampling technique. The sample of this study was fifth grade of Ungaran 02 Elementary School. Data collection techniques used were test techniques and non-test techniques. The test technique used pretest and posttest while the non-test technique used observation, questionnaires and documentation. Data analysis techniques with normality tests, homogeneity tests, independent sample t-tests and simple linear regression. The results of the study showed: (1) There was a difference in students' conceptual understanding abilities regarding the use of the Student Facilitator And Explaining model assisted by Dopesen media, with a significance value of 0.010 < 0.05 (2) There was an influence of the use of the Student Facilitator And Explaining learning model assisted by Dopesen media on students' conceptual understanding abilities with a significance value of 0.003 (<0.05).
