Stimulation Of

Every child has the right and needs for stimulation of his development. One of them is cognitive. Aspects of cognitive development can be stimulated through mathematics learning. But children can find it difficult to understand mathematical concepts because reasoning and logic are needed, whereas mathematical concepts are not concrete. For this reason, concrete media need to be used to demonstrate or illustrate the concept, the media are manipulative. The purpose of this study is to analyze articles and documents resulting from research on the use of manipulative media as a stimulation of the ability to recognize the concept of child numbers. Method: This research uses a literature review method. There are criteria in searching journals so that 20 journals are found to be analyzed based on population, sample, variables, data analysis, type of research design, and research results. Results and discussion: Literature review shows that the use of manipulative media in early childhood education varies greatly in terms of media material, its play, and its effectiveness. The manipulative media in question such as grain media, number blocks, clock puzzles, container marbles, picture cards, congklak numbers cards, numbers fishing games, and others. While the ability to recognize the concept of numbers in question such as the meaning of the symbol number of concepts a lot a little, counting, and others. Statistical analysis shows the application of manipulative media can stimulate the ability to recognize the concept of numbers in children, increase the activities of children and teachers, and found the response of children who are happy with the use of manipulative media. Conclusion: Manipulative media can stimulate the ability to recognize the concept of child numbers.

This research is qualitative research with case study method. The focus of this research is to explore the value of ethnomathematics in the culture of the Bali Mula society in the Kintamani sub-district, Bali Province. The research starts from the exploration phase of ethnomathematics, mapping ethnomathematics with school mathematics, explores aspects of pedagogy in the preservation of ethnomathematics and concludes on how ethnomathematics is applied to mathematics learning in schools. Data collection was carried out through observation of Mejejahitan activities carried out by Bali Mula women. Data from observations are then linked to the results of documentation analysis and strengthened by the results of interviews. The triangulation method is carried out to check the validity of the research data. Based on the results of data analysis there is a relationship between the activities of Mejejahitan with school mathematics. The mathematical concepts contained in the Majejahitan activity that is reflecting (reflecting) and predicting or predicting patterns. Because there is a relationship between Majejahitan activities with school mathematics, it can be said that there are ethnomathematics values in the culture of the Bali Mula society in Kintamani District, Bali Province.

Model Subject

To learn a lesson well, we need to hear, see, ask questions about it, and discuss it with others. Not only that, teachers need to "do it", that is to describe something in their own way, to show their example, to try to practice their skills and to do tasks that demand the knowledge they have gained. The problems to be studied in this research are: Does the implementation of CIRC Cooperative Learningtipe model can improve the learning outcomes of mathematics? Steps taken in this model. Subject peneliatiannya is a fourth grader elementary school, conducted in class IV in addition to researchers teaching this class, because the class has problems according to the studied. Research involving two mathematics teachers in grade IV SDN 07 Pasar Salido. One teacher as the lead researcher and one other teacher as observer. This study was conducted in 3 cycles. Each cycle has 4 stages. Namely (1) Planning, (2) Action, (3) Observation, and (4) Reflection. Data analysis was done by using comparative descriptive analysis that is comparing test value between cycles with work indicator. So the data analysis in this research is done both quantitatively and qualitatively. Test results in the analysis quantitatively based on prosestase. While the data obtained from the observations were analyzed qualitatively. Some conclusions that can be drawn from the results of classroom action research (PTK) is as follows: 1) Student learning motivation in general has increased the average of motivation is quite good at the beginning of 75% of students to 90% of students in grade IV SDN 07 Salido Market. This is according to the analysis of the researcher as follows: (1) Students are happy with the variation of the learning model that they think new and they have never been before (2) The learning material discussed is relatively understandable by the students because in the previous school level has been taught. The results of tests performed on each cycle increased, except in cycle III. In cycle I the average value of 65.40, in cycle II the average value of 69.00 and in cycle III the average value of 68.00. This is according to the observation and experience of researchers because for the material students in cycle III about the media is relatively more difficult than the material in cycles I and II.

In mathematics learning using compurter is needed. Computer-Assisted Mathematics is considered necessary in helping students to understand the lessons. Usingcomputers as a medium let the students understand the materials given,of course requires the role of teachers. Therefore it is necessary to conduct training for teachers with the aim of guiding the teachers to implement the learning process in assistance of computers to understand the materials that are difficult for students.The targets of this activity are: (1) To obtain the description of the quality of junior mathematics teachers in Computer-Assisted Mathematics (2) To increase students' interest in learning mathematics and students' understanding of the correct mathematical concepts related to materials which are abstract (3) To increase the use of Computer-Assisted media in learning mathematics. The targets of this activity are junior high school mathematics teachers in the district of Central Tomohon.Based on the results of observation and evaluation on the implementation of this activity, ofthe computer-assisted mathematics training obtained the following results: First, teachers have high enthusiasm in learning about thecomputer-assisted mathematics. Second, teachers can use computer aids in the form of mathematical software such as: (1) Geometer's Sketchpad in teachinggeometry,that is to draw the right kind of triangle and prove Pythagoras theorem. (2) Geogebra in teaching geometric transformation (reflection, rotation, dilation) and seeking solutions of SPLDV and SPTLDV. (3) Yenka to teach the matters of mathematical models. (4) Macromedia Flash products inlearningmathematics especially about planes. Overall, computer-assisted mathematics training activities, in the form of utilizing mathematics softwares, provides satisfaction for the participants. In addition, the highly perceived benefit is that teachers can use the software that has been studied in computer-assisted mathematics training to facilitate the students in understanding the concept of mathematics appropriately. Keywords: Workshops, Computer-Assisted Mathematics
