Abstract

Almost all students certainly expect to get graduation and satisfactory results when Final Semester Examination results are announced. It is because Final Semester Examination is a measurement in order to map and see the ability of students after participating in the learning process within a certain period of time, by conducting tests through various tests. Apart from depending on each individual student, there are also several factors that affect graduation and obtaining good grades at Final Semester Examination, namely the number of study hours in a day and the acquisition of Mid Semester Examination score. Thus this study aims to find out how the influence of the number of study hours in a day and the results of the midterm exam has on the graduation of the final semester exam in pharmacy mathematics. The data analysis method used is the Binary Logistic Regression method. From the research, results it is known that the independent variables study hours in a day and the acquisition of Mid Semester Examination scores have a significant effect on graduation, which is equal to 59.5%.. In addition, it is also known that the more hours of study in a day and the higher the Mid Semester Examination score, the higher the chance of passing Final Semester Examination with satisfactory grades.

Abstract. The purpose of this study was to determine the level of understanding of Elementary School Teacher Education Students as prospective teachers regarding the use of Dakota visual aids in learning mathematics. This research was conducted in the Elementary School Teacher Education Study Program, University of Quality, Berastagi, with a population and sample of 28 students in Semester 1 of the 2022/2023 Academic Year. The type of research used is classroom action research. Based on the research conducted, PGSD students have various levels of understanding about the use of the Dakota visual aid in teaching the smallest common multiple and the largest common factor. The difference in the level of understanding is caused by differences in students' cognitive abilities. The evaluation results show that the percentage of students' understanding of the five material components assessed is as follows: regarding the teaching of multiples material, 53.57% of students have an understanding in the high category and 46.43% in the medium category. For teaching factors there are 50% of students with understanding in the high category and the other 50% are in the medium category. For fellowship teaching there are 57.14% of students with understanding in the high category. 28.57% of students are in the medium category and 14.29% of students with low understanding. For KPK teaching, there were 89.29% of students with an understanding in the high category and another 10.71% in the medium category. For FPB teaching, there are 71.43% of students with an understanding in the high category, 17.86% of students with moderate understanding, and another 10.71% with a low category.

Abstract

In the process of learning mathematics, students are not only required to understand concepts, but more than that. One of the important skills mastered by students is mathematical communication skills. The purpose of this research is to see the effectiveness of problem-based learning in improving students' communication skills. This study aims to provide an overview of the quality of the research variables studied. The variables in this study consisted of two, namely the application of problem-based learning and the mathematical communication skills of students of SMP PAB 7 Manunggal. As for the subject of this study is the application of problem-based learning models and the object of this study is students' mathematical communication skills. The sample in this study were 28 grade VII students of SMP PAB 7 Manunggal. The instruments used to collect research data were questionnaires to observe the implementation of the learning process and test sheets for mathematical communication skills that had been tested for their validation and reliability levels. The data collected in this study were then analyzed to see the effectiveness of the implementation of the learning process and students' mathematical communication skills. Problem-based learning implemented at SMP PAB 7 Manunggal can be said to have been effective in terms of the implementation of the learning process with an average score of observations of 3.589 and student learning completeness reaching 75%. Because the learning process implemented has been said to be effective, data on students' mathematical communication abilities can be analyzed to see the improvement. Based on the descriptive comparison of the test result data, it can be concluded that there has been an increase in students' mathematical communication abilities, in terms of pre-test and post-test scores.

Abstract

This study aims to improve students' high-order thinking skills through Project Based Learning in Class VIII at Mts Baitul Makmur, Rejang Lebong, Bengkulu. There were two cycles in this research. Each cycle applies a project-based learning model and consists of four stages, namely planning, implementing, observing, and reflecting.  The research subjects were 26 students of class VIII B at MTs Baitul Makmur Rejang Lebong. Data were collected through observation, field notes, documentation, and tests. The results showed that the implementation of project-based learning could improve students' high-level thinking skills. This is indicated by an increase in the percentage of higher-order thinking skills from pre-cycle (cycle 1 pre-test) of 48% (poor) to 73% (enough) in cycle 1. Then in cycle 2, it increased to 82% (good). Furthermore, there was an increase in student learning outcomes through the Project Based Learning model in Class VIII, Mts Baitul Makmur Rejang Lebong. In the pre-cycle, the average score of students' mathematics tests was 53.54, with classical completeness of 4%. In cycle 1, the average score increased to 76.62, with a classical pass of 73.08%. It increased in cycle 2, the average score being 80.12 with a classical pass of 85%.

Abstract

Learning mathematics is intended so that students are able to use reasoning in identifying, analyzing and concluding a pattern and character of a mathematical object. In addition, by manipulating mathematics students will be able to generalize a concept, compile evidence or explain mathematical ideas and statements. The purpose of this study is to determine the increase in reasoning ability that occurs after implementing a realistic mathematics learning model. This study refers to a quasi-experimental research procedure with a pretest-posttest approach. The population used in this study were all students of class VIII SMP Negeri 11 Pematangsiantar with the sample being all students of class VIIIB, totaling 21 people. The instrument used in this study was a learning achievement test in the form of multiple choice objective tests with four options totaling 24 questions. The results showed that during the pre-test the average score of students was at 64.45 with a standard deviation of 4.575 and experienced an increase during the post-test with an average of 80.25 and a standard deviation of 6.25. In addition, when viewed from the completeness of learning there is also an increase, namely from 57.14 to 80.95.

Abstract

One of the viruses that cause infectious diseases is the corona virus. Corona viruses can cause more serious diseases such as the Severe Acute Respiratory Syndrome-Corona Virus which was epidemic in 2003, the Middle East Respiratory Syndrome-Corona Virus outbreak in 2012 and the 2019 Coronavirus Disease which was epidemic at the end of 2019. The ordinary linear differential equation is an equation differential in which all derivatives appear in linear form and no coefficients depend on the dependent variable. The coefficient can be a function of the independent variable, in which case the differential equation is a linear differential equation with changing coefficients. Based on the relatively large number of cells that are susceptible to infection (S), over time it will decrease and towards a zero value against high immunity, and people under surveillance and patients in care (E) with time will decrease towards high immunity. Meanwhile, the number of infected cells (I) at one time will reach a highest point, which indicates the maximum number of infected cells and gradually decreases with time towards a high increase in immunity. Because fewer S, E, and I are infected, the amount of virus in the body (R) also decreases.
