Mathematical problem solving ability is one of the most important abilities students must have to process the information provided in solving problems. Before using mathematical problem solving skills, prior knowledge becomes the most crucial thing that makes students able to connect all available information so that they can construct new knowledge through the process of assimilation or accommodation.The purpose of this reseach is to:(1) Analyze prior knowledge what student has so the student can solve the problem of tangent circle given; (2) Know how learning trajectory in student’s mathematical problem solving ability by applying metacognition approach. This reaseacrch is a design research to improve the quality of learning. In this reseacrh researchers gave 3 test questions on students’ mathematical problem solving abilities. One trial was conducted in class VIII-B and trial II was conducted in class VIII-A, each consisting of 30 students junior high school. The result of students answer analysis shows the mast problematic topic that makes the studnts are difficult to solve the problem is about the tangent cicrcle that is the elements of the circle and the concept of circle circumtance there are three phased in learning path of students mathematical problem solving skill that are under standing the problem, making the problem solving plan by prrior knowledge and doing problem solving and evaluating it. From this explanation, it is better for teachers to ensure students have sufficient prior knowledge to make it easier to construct new knowledge, as well as make the learning process fun and meaningful so that students will remember knowledge in long-term memory.

This study is development research, which aims at developing Natural Sciences (IPA) learning tools for SMP (junior high school) based on discovery learning oriented on problem solving skills and learning outcomes on acidic-base and salt material which is valid, practical and effective. The development model employed in this study referred to 4D development model, which consisted of define, design, develop, and disseminate. The learning tools developed are RPP, LKPD, BAPD, Media, and THB. The IPA learning tools for SMP based on discovery learning which had been developed was then validated by two experts. After being validated, the test of learning tools based on discovery learning was conducted at SMPN 36 Makassar in grade VII.9 with the total of 32 students. The results of the study reveal that the learning tools based on discovery learning developed which had been validated indicates that the mean score is 3.74 which is in very valid criteria. The learning tools based on discovery learning is stated as practical and effective, because the results of the practically test reveal (1) the implementation of learning tools based on discovery learning is in the average of M = 1.9 in the category of (1.5 ≤ M ≤ 2.0) meaning that the aspects and criteria observed on the implementation of learning tools based on discovery learning is in entirely implemented category, (2) the teacher gave a very positive response on the learning tools based on discovery learning with the percentage of 92.07%, and (3) the students gave a very positive response on the learning tools based on discovery learning with the percentage of 92.77%. The learning tools is also met the criteria of effective with the following results: (1) the improvement of problem solving skills of students from 27.22% becomes 74.50%, (2) the learning outcomes has met effective criteria that the average of the percentage is 83.48% with the classical completeness 87.50%, whereas, the improvement of learning outcomes based on N-gain test is 0.82 with high criteria. Therefore, the results of the study shows that the product of learning tools developed is categorized as valid, practical, and effective.

The purpose of this research was to reveal how the construction process of symbolic representation and verbal representation made by students in problem solving. The construction process in this study referred to the problem-solving stage by Polya covering; 1) understanding the problem, 2) devising a plan, 3) carrying outthe plan, and 4) looking back. This research was qualitative research by getting involved 4 students of Junior High School class VIII. This study obtained results that the construction process of symbolic representation made by students since in the process of understanding the problem. In understanding the problem, students were able to identify the problem well. Then students could make the symbol used as a variable that the value was not known. By using the symbol students could perform a series of calculation to obtain the value of the symbol. Symbols created by students were very helpful and facilitated students in solving problems. While in the construction process, verbal representation was done by students since the process of understanding the problem. The form of verbal representation was manifested by writing down all information known from a slightly changed problem because they used a language that they understood more. Based on the known information, students could plan and performed a series of calculations using written sentences so that the problems could be solved properly.
