This study aims to develop a mathematics handout based on local wisdom nuanced to increase the mathematical problem-solving skill of the Secondary students. This research is motivated by the student’s ability to solve the social arithmetic problem. This study used four phases of developmental research such as Investigation, Design, Realization, and Test, Evaluation, and Revision. The characteristics of local wisdom were acquired within the design or context in the mathematics handout to develop secondary students problem-solving skills. The results show that the students do the stages of problem-solving by Polya, get the maximum score and show students’ positive responses in the questionnaire given. Therefore, it met the proper handout criteria such as valid, practice, and effective. In the future studies, we encouraged to develop learning materials which have a guide to do phases of problem-solving and apply the way to solve some problems in mathematics.

This study aims to determine whether the improvement of students' mathematical problem solving skills that get the learning of Model-Eliciting Activities is better than students who get regular learning. Method in this research is experiment and research design pretest and postest in experiment and control class. The population in this study were all students of MTs Kota Cimahi. School samples were taken at random, and obtained by MTs Negeri Kota Cimahi. Then the sample is selected two class VIII at random class. The experimental class uses Model-Eliciting Activities, while the control class uses ordinary learning. The hypothesis in this research is the improvement of student solving abilities of MTs students in Cimahi whose learning using Model-Eliciting Activities is better than using ordinary learning. Research data obtained through the instrument of posttest mathematical problem solving ability. The posttest data is processed by normality test, homogeneity test, and two average difference test using SPSS (Statistical Product and Service Solution) software version 16.0 for Windows. The results showed that the improvement of problem solving ability of MTs students in Cimahi whose learning using Model-Eliciting Activities was better than those using ordinary learning.

This study aims to describe the ability of communication and problem solving of mathematical students in the material quadrilateral and triangle in class VII in one district of MTs Bandung. This type of research is qualitative research with phenomenology model which aims to interpret communication ability and ability to solve the mathematical problem of students. The subjects of this study were 24 students for communication skills and 25 students for math problem-solving skills. The result of data analysis shows that the mathematical communication ability of grade VII students in one MTs in Kabupaten Bandung is still relatively low with the highest percentage being in the low communication ability qualification which is 37.5%, while for students who have ability is get percentage equal to 29,2% and for students with high communication skills get a percentage of 33.3%, while for problem-solving skills in class VII is quite good with the highest percentage in qualification students with high problem-solving ability with a percentage of 44%, while for qualified students who ability is getting percentage by 40%, and for low qualifications only got a percentage of 16%.. Keywords: mathematical communication ability, mathematical problem-solving ability

El desarrollo de la resolución de problemas en el aula presenta múltiples facetas, una de las cuales se refiere a la evaluación y particularmente al uso de instrumentos evaluativos que contribuyan a la mejora del aprendizaje y que sirvan al propio resolutor para reflexionar sobre sus producciones y su manera de proceder. En este artículo se muestra como el uso de una base de orientación para la resolución de problemas puede constituir efectivamente una ayuda cuando los alumnos resuelven problemas. En particular se analiza la relación entre el número de acciones de la base de orientación que cada uno de los alumnos ha tomado en consideración al resolver un problema y sus soluciones al problema. La existencia de dicha relación permite considerar la base de orientación como un andamiaje educativo para la resolución de problemas. Problem solving classroom practices have multiple facets. One of them is related to the evaluation and, consequently, the use of evaluation devices that enhance students’ learning as they help the students to reflect on their own outcomes. In this article we analyse the use of an orientation basis as a device to support first year secondary students’ mathematical problem solving. In particular, we study the relation between the number of actions of the orientation basis in which the students were involved when they solved a problem and their solutions to the problem. The emerging existence of this relationship allows us to consider the orientation basis as a problem-solving-related form of selfscaffolding.

This study is a quasi-experimental research using factorial design. This study aimed at finding the facts that had been resulted from the different influence caused by the use of Open-Ended method and that of STAD method on the students’ mathematical problem-solving skills in terms of learning achievement. The learning achievement was categorized into two types namely the high achievement and the low achievement. The population in this study was Grade V students from SD Negeri Serayu. The data were analyzed by ANAVA univariate test. The results of the study were as follows. First, there have been differences in the mathematical problem-solving skills of the students who had been taught using Open-Ended method and those who had been taught using the STAD method. Second, there were also differences on the students’ score. For the students who had been taught using the Open-Ended method, the highest posttest average score of their learning achievement was 95.71 while the lowest post-test average score of their learning achievement was 63.92. These students’ total average score of learning achievement was 81.04. On the other hand, for the students who had been taught using STAD the highest posttest average score of their learning achievement was 95.50 while the lowest posttest average score of their learning achievement was 70.00. These students’ total average score of learning achievement was 89.13. Third, there has not been any differences between the Open-Ended method and the STAD method.
