<![CDATA[This study aims to investigate more deeply the material of linear programming with a realistic mathematics education (RME) approach. This research is a literature study with a descriptive qualitative research type with library research using various written sources such as articles from Springer, ScienceDirect, and Google Scholar. This study focuses on the characteristics of RME, the principles of RME, the steps of learning RME on linear programming material, and examples of implementing RME learning on linear programming material. From the results of previous research, it was found that using the RME approach can help students understand linear programming material. This is because real-life problems in linear programming are in line with realistic principles that exist in the RME principle, namely being able to apply mathematics in solving real-life problems and mathematics must start from problem situations that are meaningful for students.]]>

<![CDATA[This study explored how mathematics teachers improve students' thinking skills from low to higher order thinking skills (HOTS) during class. This study used a qualitative descriptive research design. The research subjects involved were mathematics teachers from one of the high schools in Malang City, East Java, Indonesia. Data were collected through a process of initial observation in schools, the results of preparing lesson plans, classroom assessments by teachers, and semi-structured interviews. The results of the research were analyzed using models, namely data reduction, data presentation, and concluding. Data focused on lesson plans based on a scientific approach and HOTS-based assessments: analyzing, evaluating, and creating. The teachers' class assessments were analyzed and classified into the HOTS cognitive level using the Anderson Krathwohls' Taxonomy indicators. The findings of this study indicate that teachers arranged the class with a scientific approach setting and provided HOTS-based class assessments to students to improve students thinking skills. But on the other hand, teachers experienced obstacles, that are students who are still passive when the scientific method was applied and the learning took a lot of time. Another obstacle related to the HOTS-based assessment is that teachers had difficulty when compiling HOTS-based assessment because it required a lot of time and thinking skill. Students also had difficulty in solving HOTS-based questions due to low reading interest and diverse student 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[Several countries continue controlling the spread of the corona virus to decrease the number of new COVID-19 cases. Currently some Southeast Asian countries require an estimate of the num-ber of daily new COVID-19 cases of in the future in order to reopen or consider lifting strict pre-vention policies. This study applies ARIMA and SARIMA forecasting models to predict the de-cline in the number of new cases in three Southeast Asian countries. The first modelling is carried out using the ARIMA model with optimized model parameters based on the Akaike Information Criterion (AIC) and Bayesian Information Criterion (BIC) analysis. Then, the Mean Absolute Error (MAE), Root Mean Square Error (RMSE) and Mean Absolute Percent Error (MAPE) are evaluated is applied a criterion to select the best model. The best ARIMA and SARIMA models are selected manually and they are used to predict the number of new cases in three Southeast Asian coun-tries. It is expected that the number of new cases in these countries will experience a significant decline in the next month from September 2021. The prediction of SARIMA model indicates a better result than the ARIMA model which confirms the existence of a season in COVID-19 data.]]>

<![CDATA[Spatial ability has been recognized as a significant human skill involving the retrieval, retention, and transformation of visual information in a special context. One type of spatial ability is the skill of performing mental rotations. Mental rotation is is the ability to rotate two or three-dimensional objects rapidly and accurately in the mind. . In other words, by way of rotating objects mentally and thereby solving problems related to space, this test includes the limit of reaction time and the rotation angle, both of which are mutually related to the degree of difficulty. The subject of this research comes from 9th grades students at junior high school in Surabaya were selected from purposive sampling. The volunteer student with high ability in mental rotation based from differences gender were selected from mathematic ability task and interviewed. The result showed that high ability male students able to visualize the result of two-dimensional wake rotation such as right triangle rotated as 45°, 90°, 180° and 360. While high-ability female students are still somewhat difficult to visualize the result of two-dimensional rotational objects such as triangle too but had difficultness when rotated as 45°.]]>
