The purpose of this research is to analyze the feasibility and effectivity of Student Activity Sheets that has been made before actually use while learning process. Methods used i.e. qualitative descriptive with the sample as many as 32 students and three expert people which include learning materials expert, linguist, and media expert. This form of research instruments in question form validation of expert teaching materials, question form validation of linguist, question form validation of media expert, question form of student responses, and Student Activity Sheet based Problem Solving Approach with teaching materials of comparative worth in grade seven. Validation by expert teaching materials amounted to 75%, validation by linguist amounted to 73, 3%, validation by media expert amounted to 96, 3%, student responses amounted to 79, 89%. It means the Student Activity Sheet based Problem Solving Approach that has been made can be used and effective as a learning media.

One of the learning efforts that are discovering the concept with the creation of the student activity sheet based approach to Problem Based Learning. The purpose of this research is to analyze the feasibility of Student Activity Sheets that have been made before actually used when the learning process. This descriptive qualitative research methods, with a sample of 33 students one of 228 West Bandung Regency. The instrument to be prepared is student activity sheet based approaches Problem Based Learning, the now expert validation material, linguist, connoisseur media, and now student response. As for the results of the research that is now 75% material expert validation, linguists 75%, 83%, and media expert question form student response 76%. It can be concluded that the students already there is an interest in working on is student activity sheet but should still be in the lead. Student activity sheet based approach to Problem Based Learning can be used in learning.

This research was motivated to analyze students' mathematical problem-solving abilities. This research is a study that uses qualitative descriptive methods. The subjects of this study were class XII students, totaling 20 students in one of the Cimahi City Aliyah Madrasas. The stages of this research start from the process of planning, implementation, and observation. The instrument problem solving a mathematical problem that is given is a question that has been tested validation by mathematicians, amounting to 5 questions. From the results of the research that has been carried out, there are difficulties in students' difficulties in solving existing problems. Students who have low level of ability, difficulty factors that occur among them students have not been able to understand the problems faced with the problem, students still have difficulty in planning the completion model that will be used in answering each question, students also still not right to determine the next line in the arithmetic sequence. So that students cannot solve the problem of mathematical problem-solving skills properly.

PENGARUH HABITS OF MIND (KEBIASAAN BERPIKIR) TERHADAP PEMECAHAN MASALAH MATEMATIK SISWA SMP Nuni Nurmala; Euis Eti Rohaeti; Ratna Sariningsih

Problem solving is identical to learning mathematics because every student learning inevitably prompted work onreserved to measure the student's ability. The purpose of this research is to know the student's problem solving abilities. The method used is descriptive qualitative methods Researchers acted as observer, giving the question of tests and question form on the students. Test instrument in the form of descriptions and question form Habits Of Mind (habits). The subject of research that is grade VII. Researchers using an indicator of problem solving: understanding the problem, devise a plan of resolution, carry out the plan of settlement, check back. From the results of the tests given. Habits Of Mind affects the student's problem solving ability and the students is hampered in its execution completion indicators and check back for answers.
