Factors affecting the grade point average students of FMIPA Universitas Negeri Padang with binary logistic regression model
Get PDFToday, everyone places a high importance on their education. Learning is how education is implemented, and learning allows people to reach their full potential. Since learning is a process and learning achievement is the end consequence of the learning process, learning and learning achievement are inextricably linked. Learning achievement levels are assessed using GPA (Grade Point Average). Allowance, gender, major, status of residence, school location, study time, admission type, duration of gadget use, and personality type are all factors that affect GPA. In order to identify the components that influence academic accomplishment, a model must be developed since it can be understood, explained, controlled, and forecasted. This study's goal is to identify the binary logistic regression model, which describes the variables influencing the faculty of mathematics and natural sciences at Universitas Negeri Padang's GPA. The aim of this study is to identify the logistic regression model that represents the variables that affect the GPA of the Faculty of Mathematics and Natural Sciences at Universitas Negeri Padang. Secondary and primary data were employed in this study, and questionnaires were used to collect the data. The 2020 students made up the study's sample, which included 293 respondents. According to the study's findings, factors such as gender, major, admission type, and duration of gadgets use may have an impact on students' GPAs at the Faculty of Mathematics and Natural Sciences at Universitas Negeri Padang.

The view of mathematics education as science
Get PDFThis paper will discuss the view of mathematics education as science. This study is the result of a variety of relevant literature related to mathematics education as a science in a scientific discipline. Philosophically, mathematics is considered as the queen of science used by humans in everyday life. While knowledge itself is closely related to philosophy, where these two terms cannot be separated from each other. The science of studying natural phenomena itself. Science is the product of epistemology, ontology, and axiology. Philosophy and science are two similarities in that both seek the truth. A person who seeks the truth is a philosopher or philosopher. The source of philosophy is man, reason, and the human heart. For example, mathematics. Mathematics is a science about reasoning, about patterns and mathematics is the queen of science and at the same time a servant of science. Mathematics education is a mathematics lesson that makes students build logical thinking and build mathematical knowledge
Describe mathematical creative thinking skills and problem-solving strategies by prospective teacher students on non-routine problems
Get PDFThis study aims to investigate and describe how creative thinking skills and problem-solving strategies are used by prospective mathematics teacher students in solving non-routine problems. Non-routine problems given to the subject require the use of mathematical conceptual understanding and procedural knowledge or algorithms used to find solutions to solve them. The results of the analysis of student-teacher solutions show that each student uses at least two problem-solving strategies. The most frequently used strategies are using algebraic manipulation, making logical reasoning with diagrams/models, and trial and error. Students with high categories show proficiency in using appropriate problem-solving strategies and students with lower categories still show an introduction to solving strategies so that they are confused about choosing the right strategy for a particular problem
Prediction of the number of daily active COVID-19 in Indonesia
Get PDFIn 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
Logistic-Empirical Model For Students Susceptibility To Harmful Einstellung Effect in Mathematics Instruction
Get PDFHarmful Einstellung effect creates a serious source of aversion for students in Mathematics. It may not be clear whether students fail Mathematics due to lack of knowledge or due to aversion arising from Einstellung effect. This study therefore investigated students’ susceptibility to harmful Einstellung effect in Mathematics instruction using logistic-empirical model approach. A cross-section of senior secondary school (SS 2) students of Alvana Model Secondary School Owerri, Imo State numbering 93 were continuously observed (using direct observational technique with observation schedule) and surveyed to decipher their susceptibility to harmful Einstellung effect. The result indicates increasing susceptibility to harmful Einstellung effect. That is, a high prevalence of Einstellung phenomenon was observed among students. It is important to note that this has consequently resulted in the increase of aversive behaviour in Mathematics learning. It was recommended among others that teachers should inform the students about harmful Einstellung effect during teaching and encourage them to think critically about any mathematical problem before finding solutions. Also, teachers should adopt some approaches when teaching Mathematics, such as, delayed formalization approach and target task approach
