Abstract

Problem solving is a process or thinking activity to solve a problem. Mathematical problem solving skills is needed for students both in the process of understanding mathematics itself and in everyday life. The problem solving can be achieved by implementing the learning using problem solving approach which train students to deal with various problems including individuals and group problems to be solved individually or together. This learning is oriented towards the investigation and discovery which is basically solving the problems. It is the basis for students to solve problems critically, systematically, logically, and creatively as well as the ability to collaborate effectively and to present fundamental knowledge which in turn can improve the solving skills. This study aimed to examine whether the improvement of mathematical problem solving skills of students learned with the problem-solving approach was better than students taught using the conventional learning. The improvement was examined in general and based on the students’ levels. The study also aimed to investigate an interaction between the learning (problem solving and conventional approach) and student levels (high, medium and low) in increasing mathematical problem solving skills. This study applied a pre-test and post-test control group design. The population of the study were Year 7 students of one of junior high schools in Pidie, Indonesia, consisting of seven classes in 2017/2018. Two classes, a control and an experimental class, were selected as the sample through purposive sampling technique. The instrument used to obtain the data is the mathematical problem solving skills test. The data was then analyzed by employing a two-way ANAVA test using SPSS. The results of the study showed that the improvement of mathematical problem solving skills of the students learning with the problem-solving approach is better than the students experiencing the conventional learning, reviewed in general and based on student levels. There is no interaction between the learning models and student levels on mathematical problem solving skills. The results are expected to be used as a reference for mathematics teachers to apply the problem-solving approach in the learning process to improve mathematical problem solving skills.

Abstract

Geometry is a branch of mathematics that is taught with the aim that students can understand the properties and relationships between elements of geometry and can be a good problem solver. There are still many students who have difficulty learning geometry. One of the causes of students' difficulty in understanding geometry is that the learning strategies used are not in accordance with the material being taught. In addition, in geometry learning so far has not been adjusted to the level of development of students' thinking. Therefore an appropriate strategy is needed which is arranged based on the level of development of students' thinking in geometry. Van Hiele's theory-based learning is learning that is adapted to students' thinking stages, so this learning is appropriate if applied in geometry learning. The purpose of this study was to determine the improvement of geometry problem solving abilities between students taught by cooperative learning based on Van Hiele theory with conventional learning reviewed by students and based on student level. This study uses an experimental method with a pretest-posttest control group design design. The instrument used is a geometry problem solving test. The population in this study were students of class XII SMA Negeri 1 Sakti, Pidie Regency, Aceh Province, and the randomly selected sample consisted of two classes into the experimental class and the control class. The data analyzed is data N-gain problem solving ability. From the results of the data analysis, the improvement of students 'geometry problem solving abilities that obtain Van Hiele based learning is better than students who obtain conventional learning in terms of overall students and based on students' level of ability. Thus, in geometry learning it is recommended to apply learning based on Van Hiele theory so that students' geometry problem solving skills can be improved.
