Abstract. This study is a classroom action research. The purpose of this research is (1) to describe the application of problem solving method in improving mathematics problem solving students of mathematics education program of Catholic University of Santo Thomas North Sumatera and (2) to describe the improvement of mathematics problem solving ability of mathematics education student in Algebra and Trigonometry. The result of this research shows that the result of problem solving test of mathematics cycle I is students who do not have problem solving ability as much as 3 people (30%), while students have math problem solving ability as much as 7 people (70%) and percentage of observation sheet lecturer activity amounted to 70.90%. Based on the result of math problem solving test in cycle 2, there were 1 (10%) students who did not have the ability to solve mathematics problem, while the students who have problem solving ability 9 students (90%) and lecturer activity percentage of 85.50% experienced an increase from cycle I of 6.5%. Based on the results of this acquisition then the group (classical) can be said that students have the ability to solve problems in Algebra and Trigonometry courses and increase problem-solving abilities by 20%. Keywords: problem solving method and problem solving ability.

This study aims at presenting our efforts to build a methodological tool to assess the quality of teaching in a math problem solving lesson based on Lesson Study method, and to contribute to practical orientation of the pre-service and in-service mathematics teachers. We rely on authors of mathematics education who studied problem solving, teaching practice and the performance of students. The instrument called “Quality Assessment of Instruction in Problem Solving” (QAIPS) was validated in the qualitative and interpretative ways. Some items that construct the instrument are here justified through empirical situations, which brought to the front discussions that expanded the analysis of the instrument. The QAIPS proved potential for the desired purposes.

This study aims to determine whether are differences in problem solving skills of mathematics students using cooperative learning type TAI and NHT in class VII SMP Negeri 3 Pulau Rakyat. This type of research is quasi experiment. The population in this study is all students of grade VII semester 2 SMP Negeri 3 Pulau Rakyat consisting of 5 classes with total 160 students and the sample of this study are VII-1 and VII-3 as many as 64 students. The required dara is obtained by using the students’ math problem solving test in the form of a description of 4 question. From the results of data analysis obtained the average test results of students mathematics problem solving abilities through cooperative learning type TAI is 27,28 with varians 2,65 and the average test result of students’ mathematics problem solving abilities through cooperative leraning type NHT is 22,25 with varians 3,28. To test hypothesis used t test, from the calculation results obtained tcount with the test reject Ho and accept Ha if tcount  1,6697 so it looks  that tcount is not reside in the Ho accetance area which means Ho rejected and Haaccepted or in other  words there are differences problem solving ability of mathematics students using cooperative learning type TAI and NHT in class VII SMP Negeri 3 Pulau Rakyat. Keywords: Mathematical Problem Solving Abilities, TAI, NHT

This article describes how Mullin, in collaboration with two college instructors, designed and carried out an action research study to answer her own instructional questions. Action research is a process of studying some aspect of teaching through the use of disciplined inquiry (Association for Supervision and Curriculum Development 1995). Teachers engage in action research to improve their instructional practices on the basis of a deeper understanding gained through the collection and analysis of relevant data. Action research can take place on three levels: an individual teacher might examine his or her classroom, a group of teachers might collaborate to research a shared interest, or an entire school might research an issue. In this study, the teacher-researcher looked most directly at the aspect over which she had control: the nature of instruction in mathematics problem solving.

Metacognitive blindness is usually synonymous with low math ability. However, this study reveals the opposite. Metacognitive blindness can also be experienced by students with good learning achievement. This research was conducted on students majoring in Mathematics Education who have the best academic achievement in their class. The data collected is in the form of words obtained through interviews after solving math problems. The results of the qualitative analysis show that subjects who are students with good academic performance can experience anomalous results during the problem-solving process, which is a condition in which the subject feels that the math problem at hand contains errors. The error in question is, the subject stutters the squares on the chessboard that are not the same size, but in reality they are not.
