In Indonesia, the coronavirus disease (COVID-19) decreased from April to May 2022 and in-creased slowly from May to June 2022. Statistical predictions are needed to monitor the increase in cases of this pandemic spike, as happened at the end of February 2022. This study aims to predict the rise in the number of active COVID-19 cases by applying the autoregressive integrated moving average (ARIMA) mathematical model. and multiple linear regression (MLR). Daily observation data of active cases, new cases, recovered cases, and deaths were recorded from January to June 2022 totalling 152 observations. Then ARIMA modelling for active cases and MLR modelling for daily active case observation data that depended on new cases were carried out , recovered, and died. Furthermore, the prediction results from the two models were determined the root mean squared error (RMSE), the mean absolute error (MAE), and the mean absolute percent error (MAPE). From the calculation results, the ARIMA model is smaller than the MLR. However, the prediction of the next thirty days in the MLR model is close to the actual value, while in the ARI-MA model it is below the actual value.

Analysis of Communication and Information Science Education Inclusivity in a STEM Environment in Zimbabwe Alois Matorevhu
International Journal of Trends in Mathematics Education Research Vol 1, No 2 (2018)
Publisher : SAINTIS Publishing

Communication and Information Science (CIS) can be effectively applied in a STEM environment if ICT is accessible to people including those who are visually impaired (VI). This is premised on that Information and Communication Technology (ICT) has invaded every part of society, from home, industry and social life, as the world moves rapidly into digital media. One way of ensuring the effective inclusion of VI people in communication and Information Science is to have an education system from preschool, secondary through to tertiary which has inclusive ICT education. Apart from engendering CIS, ICT promotes/enhances student-centered learning consistent with STEM objectives. Through Zimbabwe’s education system, the visually impaired (VI) people like anybody else, need to understand and apply ICT as a tool to aid their learning, professional development, and a means of socializing. What is questionable is whether the education system of Zimbabwe from preschool, prepares VI people to be effective users of ICT as STEM objectives suggest. In order to gain insight, curricula documents for a selected teachers’ college T and Ministry of Primary and Secondary Education curriculum documents were analyzed. Also, data was generated through interviews and focus group discussion with VI pre-service teachers at teachers’ college T. The interviews and focus group discussions aimed to generate data through VI pre-service teachers’ reflections on their primary and secondary school days, juxtaposed with their current experience during teacher training with respect to inclusivity on use of ICT as a tool for teaching and learning, aiding personal learning and social life interactions. All the 10 VI pre-service teachers involved in the study concurred that if ICT learning and application begins as early as primary level, one is bound to develop high competence and confidence in ICT use. However, a very supportive environment, morally and materially, was seen as crucial in developing high competence and confidence levels of VI persons in using ICT for learning and in social life.

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.

This qualitative research aims to describe profile high order thinking skill (HOTS) of Junior high school students’ grade 8 in solving linear equation system problems based on kinesthetic and visual learning styles. In collecting data, mathematics ability test and learning style questionnaire aims to select students to be research subjects. Then, problem solving tests to determine the high order thinking skills and interviews were used to obtain data on students' high order thinking skills that were not obtained from problem solving tests. There are 3 (three) aspects of HOTS in this study which are analyzing, evaluating and creating. The results of the study show that in the aspect of analyzing, students with kinesthetic and visual learning styles can distinguish the information needed, know what is sought and know the relationship between information. In creating aspect, kinesthetic and visual aspects can know ideas, strategies used and can implement these ideas and strategies in solving problems. Whereas in the Evaluation aspect, kinesthetic uses a strategy in checking the truth in the answer but the visual does not use the strategy. Thus, it can be concluded that the differences of kinesthetic students and visual students lay on strategies used in checking the truth of the answers of the problem given.

Publisher : SAINTIS Publishing

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.
