Abstract

Some abilities are needed to solve word problems, one of which is the ability to understand sentences and symbols in the problem. One factor that affects the ability of each student is learning style. Learning style is a person's tendency to receive and process information to the maximum, learning styles can be grouped into three, namely visual, auditory, and kinesthetic learning styles. The purpose of this study is to analyze and describe the forms of errors made by students in solving social arithmetic word problems in terms of the learning styles. Data collection procedures in this study are giving learning style questionnaire, written test, and interview. The research subjects are two VII grade students at SMP Negeri 1 Malang from each learning styles. The results of the analysis of this research are that students with visual learning style error occurs at the step of devising a plan, carriying out the plan, and looking back. While students with auditory and kinesthetic learning style error occurs at the understanding the problem, devising a plan, carriying out the plan, and looking back. The error forms occur in all learning styles.

Abstract

The spread of the Covid-19 outbreak has a direct impact on the economic sector. The impact of Covid-19 on the economic sector can be seen from Non-Performing Loans (NPL). Credit financing affects the Financial System Stability. Furthermore, households are the sector most affected by Covid-19, because household income is obtained from other sectors that are also affected by the spread of Covid-19. This impact can be seen in terms of income, savings/assets, and consumption. This study aims to analyze the impact of Covid-19 as measured by the variables of income, savings/assets, and consumption on household credit financing using the Logistic Regression Model. The modelling results show that the consumption and savings variables do not have a significant effect on household credit financing, while the income variables have a significant effect and are able to predict 15.5% of the variability of household credit financing. Furthermore, based on the odds ratio value of the model, information is obtained that the effect of decreased household income during the Covid-19 pandemic affected one time on the value of the odds ratio for household credit financing. Overall, the model was able to predict the data correctly by 81.4%.

Abstract

This study aims to analyze and describe the process of mathematical reflective abstraction of students with high early mathematics ability in problem solving based on Krulik and Rudnick's steps on geometry material. This research is a case study qualitative research. The research subjects were students of MAN 1 Ngawi who were taken by purposive sampling technique. The data collection technique was done by task-based interviews. The results of the problem solving task and interview data are then presented and analyzed using descriptive analysis. The results of this study indicate that students who are highly capable in every step of problem solving according to the Krulik and Rudnick stages always bring up a complete reflective abstraction which includes recognition, representation, structural abstraction, and structural awareness. Subjects utilize previous knowledge related to trigonometry in solving geometric problems. In reflective abstraction activities, it can be seen how students construct conceptual knowledge, by providing reasons for the decisions made. This is in accordance with the demands of learning in the new normal era, students are required to construct their own mathematical knowledge.

Abstract

Pneumonia is one of the leading causes of death in children in the world. The World Health Organization (WHO) estimates that this disease causes 16% of deaths in children under 5 years of age worldwide. Pneumonia is included in the top 10 diseases that suffer the most every month at the RSUD dr.Tengku Mansyur Tanjungbalai, throughout 2019 there were 73 children under five years with pneumonia and 5 of them were declared dead without hospitalization. This study is useful to find out the results of the classification accuracy of the classification and regression trees (CART) for risk factors for pneumonia in children under five years. CART classification is done by dividing the total data of under-five patients with the ratio of 15% testing data and 85% learning data. The classification accuracy obtained for the prediction data was 50% with the percentage of sensitivity and specificity of 94,12% and 14,29% respectively.

Abstract

Online learning now days, learners experience a decrease in the understanding of learning materials. This happens, because the learning media used by teachers still uses conventional learning media such as Ms.word / PDF. Moreover, learners are required to learn independently. Therefore, a learning media is needed to help students overcome the problem. This research is a website-based learning media development research that aims to help students in the online learning process, as well as knowing the feasibility of learning media using google with a metacognition approach to problem solving. The data collection instruments used are observations and questionnaires. The development of this learning media, is done by the ADDIE (Analysis, Design, Development, Implementation, and Evaluation) method. Technical data analysis is carried out qualitatively to measure data descriptively and quantitatively to calculate the score of the feasibility trial results of learning media that researchers have developed. The results of this learning media development research based on the feasibility of learning media earned a percentage on an 83% basis with excellent categories. For trials the metacognition capability of problem solving obtained a percentage of 76% with good categories. Thus, the learning media of mathematical learning media using google that researchers developed is very feasible to use.

Abstract

Creative thinking skills are one of the skills that must be developed in order to pursue developments in the 21st century. The development of creative thinking skills must be applied within a formal education level. One of the areas of study taught in formal education is mathematics. Mathematics can be used to solve problems in everyday life by using mathematical modeling. This study aimed to analyze the students' mathematical creative thinking skills in mathematical modeling with descriptive design. The steps on this research consisted of designing a test of creative thinking skills; Interviewed test results of mathematical creative thinking skills; and analyzed student answers results on mathematical creative thinking skills tests. The subject of the study consisted of 65 of junior high school students of class VIII. Findings demonstrate the skills of creative thinking students in modeling in the category of students with high mathematical abilities is that students can create unique models and seek solutions using different ways with logical and systematic, in medium category, students have a tendency to use trial and error methods as well as procedural ways to test models made, while in low category, students tend to use trial and error Test the model and resolve the problem.
