<![CDATA[The resulted of a survey conducted by the Organization for Economic Cooperation and Develop-ment based on the 2018 Program for International Student Assessment were obtained from 78 countries, Indonesian students ranked 72nd in math ability. The reason is that the 2013 curricu-lum that has been implemented in Indonesia is eurocentric. The transformation sought in the field of education is the improvement of high order thinking skills and mathematical abilities. Educa-tion and culture cannot be separated from regular daily life because culture covers all aspects of life while education is a primary need for everyone. This study used the Research and Develop-ment (RD) method with the Martin Tessmer (1993) model, which is formative research. The validity of the values obtained above 0.80 means that the questions are valid. The level of practi-cality of the questions obtained is 96.25%, very practical category. The reliability coefficient of 0.891, reliable. The level of difficulty is known to be 80% of the items in the medium category, 20% of the items in the difficult category. The discriminatory power of the question is known to all items (100%) in good category, meaning that good questions are used to classify the level of stu-dents thinking abilities.]]>

<![CDATA[This study investigated the skills of math gifted students in high school to solve math problems. Specifically, the researcher took two factors: gender and ethnicity, as differentiators. This study involved 36 mathematically gifted students from three different schools who were randomly se-lected from 48 gifted students who were identified. The two data collection instruments used were mathematical problems (Number Theory, Algebra, and Geometry) and questionnaires, which were organized by referring to Lester's problem-solving stages. The results of the two-way ANO-VA test revealed that the average math problem skill score was 50% of the maximum score (rela-tively low). Another important finding, statistically, there is no difference in math problem skill scores based on either ethnicity or gender. This study implicitly shows that mathematically gifted students in problem-solving processes were not correlated with ethnicity or gender.]]>

<![CDATA[Mathematics learning still tends to be structuralistic and mechanistic. It resulted in students' difficulties and errors in understanding mathematical concepts and principles. Whereas mathematics is a human activity that is always in contact with their culture. One of the cultures that becomes the starting point for learning mathematics is a traditional house, such as the “Rumah Tuo”. The purpose of this study was to describe the mathematical activity at the Rumah Tuo. This type of research is a qualitative-research with an ethnographic approach. The research instrument used in the form of observation, interviews, and documentation. The results of this study are that there are mathematical activities carried out at Rumah Tuo, namely counting activities using Gantang Biheh, measuring activities in making poles in the form of a 16-sided prism, and designing traditional houses in such a way that they can be shaped like ancient means of transportation, namely ships. The conclusion of this research is that there are three mathematical activities through the “Rumah Tuo” culture, namely measuring, designing and calculating.]]>

<![CDATA[This study aims to describe the mathematical literacy of Indonesian students based on research articles published in the last decade. This study used a systematic literature review method by collecting 163 relevant journals and then re-selected to meet the inclusion criteria and the criteria for assessing the quality of study results. It was found information on the development of research analyzing the mathematical literacy of Indonesian students starting from elementary school, junior high school, high school, and College Level. The literacy level of students at the elementary level is still considered low, while at the junior high school level it is assessed from various perspectives ranging from the low mathematical literacy of students to the factors that influence it. At the high school level, students' mathematical literacy is also still low even though a mathematical literacy test has been carried out in the Indonesian context. Finally, mathematical literacy at the university level is found that different student learning styles will go hand in hand with different mathematical literacy abilities.]]>

<![CDATA[This study aims to determine the effect of information computer technology (ICT)-based learning media and learning discipline on the effectiveness of mathematics learning process. The experi-ment was carried out in two groups where each group was given different treatments. The first group was taught using ICT-based learning media, while the second group was taught using conventional learning media. Each group was further divided into two categories according to their level of discipline, namely groups with high levels of discipline and groups with low levels of discipline. The method used in this research is an experiment with a treatment by level analysis model. The type of test used is Anova Two-Way. Based on the results of the analysis, it shows that the group taught using ICT-based learning media obtained a higher effectiveness of learning pro-cess than the group taught using conventional learning media. and groups that have a high level of discipline get a higher effectiveness of the learning process than groups with low levels of dis-cipline. and it is also evident that there is an influence of the interaction between the use of ICT-based learning media and the level of discipline on the effectiveness of learning process.]]>
