Abstract

The main purpose of this study was to compare and examine the effectiveness of problem-posing and think-pair-share cooperatives' learning models on mathematical problem-solving skills and mathematical communication skills. This study was experimental research with a quasi-experimental design. The samples of the study were 41 students for classroom experiments and 40 students for classroom control. The instruments employed in this study were pre-test and post-test. The instruments were made in essay forms which design to measure students’ mathematical problem-solving skills. The result of the study showed that problem-posing and think-pair-share are very effective to improve students’ mathematical achievements. However, between the problem-posing and think-pair-share, the think-pair-share is more effective than problem-posing, view from the standards of mathematical problem-solving skills and mathematical communication skills of Junior High School students.

Betawi culture has been formed through a long process, but in fact the culture is displaced. One of the things that make Betawi tribe still exist and can be recognized is because of the assimilation process of various tribes in Indonesia. Betawi ethnic is created by the various arts of culture, language, and humans. The simplicity factors of the cultures make Betawi ethnic is accepted in all levels of Indonesian society. Intercultural communication patterns of the language which is used by Betawi people, have cultural backgrounds that affect their daily language. The multi-ethnic populations give a nuance of the heterogeneous city life in Batavia. This study uses a qualitative approach, the results of this research shows that the patterns and the cultures of Betawi produce the structure, the language and Betawi culture which is simple or easy to say and tends to “ceplas ceplos” in articulation words. Beside that it is found the communication culture of Betawi character which is shown from the openness attitude, family spirit, cooperation and respect for other people's cultures.
