Abstract

This research is motivated by the low ability of students' mathematical problem solving. The purpose of research to determine the effect of Problem Based Learning (PBL) model of learning to improve students' mathematical problem solving abilities. This research was conducted at SMP Alijtihad II Kutabaru Tangerang Regency. The research method used is quasi experiment with design of non equivalent control group design. Sampling was done by using purposive sampling technique, student of class VIIIB as experiment class using PBL model and class VIIID students as control class with conventional method. The instrument used is a test to measure the ability to solve mathematical problems in the form of a description. Test instrument data were analyzed using the t-test and the Mann-Whitney U Test. Based on the result of calculation using t-test at 0.05 significance level, obtained tcount ? ttable (3,3841 ? 1,9966), so that PBL learning model can influence student's mathematical problem solving ability. The Mann-Whitney U Test showed that Zhitung ? Ztable (2.82 ? 1.92) thus enhanced mathematical problem-solving abilities in the class using the PBL model better than the conventional method. The improvement of students' highest mathematical problem solving abilities in the PBL class is on the indicators of planning the completion, whereas in the conventional class is on the indicators understand the problem

The instrument used is a test to measure the ability to solve mathematical problems in the form of a description. Test instrument data were analyzed using the t-test and the Mann-Whitney U Test. Based on the result of calculation using t-test at 0.05 significance level, obtained tcount ≥ ttable (3,3841 ≥ 1,9966), so that PBL learning model can influence student's mathematical problem solving ability. The Mann-Whitney U Test showed that Zhitung ≥ Ztable (2.82 ≥ 1.92) thus enhanced mathematical problem-solving abilities in the class using the PBL model better than the conventional method.

Abstract

This study aims to overcome students' difficulties in understanding the material continuity of functions through the use of structured worksheets in differential calculus courses. The research subjects were second semester students of the Mathematics Education Study Program, Faculty of Teacher Training and Education (FKIP), University of Muhammadiyah Tangerang (UMT). This type of research is Classroom Action Research which is carried out in two cycles where each cycle consists of two meetings. Continuity of Function material consists of several parts, namely set intervals of numbers, limits of functions and graphs, function continuity tests. The data obtained in this study are the activities and abilities of students in understanding the material. Student activity data was obtained by observing while student abilities were obtained by using a student understanding ability test. Furthermore, the data collected in this study were analyzed by descriptive analysis. Results analysis was carried out in each cycle to determine the success of using structured worksheets in overcoming student difficulties. The percentage of students who experience difficulties in cycle 2 is 26.92%. This figure is in a weak qualification with a range of 20% - 40% of the number of students, thus indicating success in this classroom action research. Thus the use of structured worksheets can overcome students' difficulties in understanding the continuity of functions material.
