Remedial is a program designed in line with students’ need that aims to improve their understanding of a topic before the student move forward to learn the next following topic. The implementation of remedial in Indonesia, particularly in Aceh, does not meet the requirement, because most of the teachers conduct a remedial by repeating the test or giving additional assignment. This study aims to design and develop an e-learning based remedial program to improve remedial in teaching and learning upper secondary schools mathematics. This study is developmental research employing System Development Life Cycle (SDLC) model. The model has five stages of development that are─: planning phase, analysis phase, design phase, implementation phase and support phase. It is important to note that this paper reports results of planning phase, analysis phase, and a preliminary-part of design phase. The result from planning phase revealed problems regarding to the implementation of remedial programs in schools. In the analysis phase, the results showed that, ─ in delivering a remedial program, most of teachers gave the same questions as they provided for examination without any extra lesson or tutorial for the students. In addition, there was no teacher who used e-learning for the remedial.

Ethnomathematics studies mathematical ideas in various cultural activities practiced by ethnic, social or professional groups. This research was carried out as part of the exploration and inventory of ethnomathematics to reveal mathematical representations and formulate a system of calculations used in the Marosok trading tradition by the Minangkabau tribe in West Sumatra. The Marosok buying and selling tradition is the tradition of shaking hands with “marosok” or touching fingers covered with cloth (cover), between sellers and buyers with the aim of obtaining price agreements in buying and selling livestock using nonverbal communication. Qualitative approaches and ethnographic methods through the principles of data collection such as field notes, unstructured interviews, and documentation studies were used in this study. The findings of this study show that mathematical representations of finger symbols and gesture in the Marosok tradition contain basic numbers one, two, three, four, five and two and a half as well as two types of operations, namely addition and subtraction. This mathematical representation is used to obtain other numbers needed in livestock buying and selling transactions using a certain formula.

Pedagogical Content Knowledge (PCK) is a blend of understanding teaching material (content knowledge) and understanding of ways to educate (pedagogical knowledge) that need to be possessed by a teacher. The purpose of this study was to find out the profile of the Pedagogical Conten Knowledge (PCK) of prospective teacher students, knowing the role of prospective mathematics teacher students towards PCK. This research is a qualitative study that describes the ability of PCK students of mathematics teacher candidates. A teacher in carrying out his professional duties must have competence that is always maintained. Therefore, competency development is an important requirement to ensure that the quality of learning in the class adapts to the development and demands of the times. Competence that is always maintained also ensures that the implementation of education is consistent in achieving educational goals. There are ten PCK criteria that must be possessed by prospective teacher students before practicing in the field. Teacher candidates must also be able to implement learning, knowledge about ways to represent and explain a material to make the material understandable to others.
