This research is motivated by the importance and still not optimal problem solving ability of student mathematical problem. This study examines the improvement of students 'mathematical problem-solving abilities that acquire Guided Inquiry learning with Concrete-Representational-Abstract approach (ITCRA) and students who have received conventional learning, in terms of overall and math skills categories KAM (high, middle, low). This research is a quasi experiment with non-equivalent control group design. The population is grade VIII SMPN 1 Padang Panjang Lesson Year 2014/2015, and the samples are two classes from seven existing classes. Instruments used in the form of tests, observation sheets, and interview guidelines. The data obtained were analyzed using the difference test, ie t-test and mann-whitney. The results showed that: 1) The achievement and improvement of mathematical problem solving ability of students who received ITCRA learning overall better than those who received conventional learning, 2) the increased mathematical problem solving ability of moderate KAM and low KAM better than those with conventional learning, whereas in high KAM, students who received ITCRA learning was no better than that of conventional learning, and 3) there was a difference in the improvement of students' mathematical problem solving abilities of high KAM categories with KAM moderate and low category students who received ITCRA learning. However, there were no significant differences between moderate and low KAM category studentsKeywords: Guided Inquiry, concrete-representational-abstact, problem solving

The Difference

The purpose of this study was to determine the differences in the improvement of students' mathematical problem-solving abilities with the Contextual Teaching and Learning approach in the material of the two-variable linear equation system in class X SMA Negeri 2 Pematangsiantar. This study used an experimental method with the aim of being in accordance with the previous statement to determine the difference in students' mathematical problem-solving abilities with a contextual approach and an expository approach, with a randomized pretest-posttest control group design. The average increase in problem-solving abilities in the control class was 0.1688 while the increase in problem-solving abilities in the experimental class was 0.0085. By using the t-test (SPSS), with a value of Fcount = 10.907 and a significant level of 0.05, a significant probability is obtained 0.002 <0.05, it can be concluded that there is a difference in normalized gain or an increase in problem-solving ability with conventional and contextual approaches. Based on the average gain of the control and experimental classes, the increase in the control class using the conventional approach is higher than the experimental class with the contextual approach. The difference in increasing problem-solving abilities in conventional classrooms is possible due to differences in students' entry-level abilities, which can be seen in the average pretest of each class.

Problem-solving is a process or thinking activity to solve a problem. Mathematical problem-solving skillis needed for students both in the process of understanding mathematics itself and in everyday life. The problem solving can beachieved by implementingthe learning using a problem-solving approachwhich trains students to deal with various problems including individuals and group problemsto be addressed individually or together. This learning is oriented towards the investigation and discovery which is solving the problems. It is the basis for students to solve problems critically, systematically, logically, and creatively as well as the ability to collaborateeffectively and to present fundamental knowledge which in turn can improvethe solving skill. This study aimed to examine whether the improvement of mathematical problem-solving skillof students learned with the problem-solving approach wasbetter than students taught using the conventional learning. The improvement was examined based on the students’ levels. This study applied a pre-test and post-test control group design. The population of the study was Year 7 students of one of the 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 skill test.The data was then analyzed by employing a two-way ANOVA test using SPSS. The results of the study showed that the improvement of mathematical problem-solving skill of the students learning with the problem-solving approach is better than the students experiencing the conventional learning, reviewed based on student levels. There is no interaction between the learning models and student levels on mathematical problem-solving skills. The resultsare 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.
