The goal of this research is to determine the influence of the realistics mathematics education (RME) approach by oriented higher order thinking skills (HOTS) on the results of students’ mathematics learning on the subject of the calculus in SMAN 10 and SMAN 12 Padang. The method used is the experimental research with pre and post-test design randomized control group. The data analysis technique used is the test for normality and homogeneity test followed by using a t-test. The results revealed that there were an increase in student mathematic learning outcomes approach realistic mathematics education oriented higher order thinking skills in class XI MIPA SMAN 10 and SMAN 12 Padang. There is impact-oriented approach to realistics mathematics education approach by oriented higher order thinking skills to understanding student learning in class XI SMAN 10 and 12 MIPA Padang.
Modern portfolio theory told us that investors are tend to optimize the expected return of investment subject to a target of risk perception. In the real world, risks are depend on may factors, such as systematic risk (market risk and macroeconomics risk which can not be controlled to diversification) and non-systematic risk (specific company risk which can not be controlled through diversification). Applying Security Market Line Approach, constrained maximization and considering changes in economic situation between 2010-2020, we found that Modern Portfolio Theory can improve portfolio performance when limited impact is spotted on minimizing systematic risk of portfolio.
This study aims to determine the effectiveness of Student Worksheet (LKPD) based on 4'Cs skills and its effect on improving higher-order thinking skills of class VIII SMPN 4 Pekanbaru. The design used in this study was pre-experimental with the Static Group Comparison design. The data analysis technique was performed using statistical t-test. The results showed that this LKPD was declared effective as a learning innovation based on indicators of higher-order thinking skills. The effectiveness of the LKPD based on 4'Cs skills is proven to be influential in improving higher-order thinking skills based on the acquisition of results using the difference test.
This study aims to analyze the high-order thinking skills of students in solving contextual problems in calculus lectures. Currently, students are required to be more creative in solving calculus problems that lead to High Order Thinking Skill (HOTS) thinking, where students apply the knowledge and skills that have been developed during lectures in a new context. This type of research is qualitative, with a descriptive presentation method and a case study approach. The subjects in this study were six students of the January-June 2020/2021 semester mathematics education study program who were selected based on their level of ability to solve contextual questions. The data collection techniques used in this study were observation and written tests presented in contextual problems. Based on the research results, it can be concluded that student HOTS is determined by the student's ability to solve contextual questions, the higher the student's ability to solve contextual questions, the more HOTS indicators are achieved. HOTS students with high abilities are able to meet indicators of analyzing, evaluating, and creating. HOTS students with moderate ability are able to meet the indicators of analyzing and evaluating. HOTS students with low ability are able to only meet the analyzing indicators, The results showed that there were differences in HOT problem solving among students with high, medium and low abilities.
After the emergence of the Covid-19 outbreak, the education system began to look for the latest innovations to form an effective lecture process with a learning model that was suitable for students in distance learning using the E-Learning learning model which was been adaptive additional information was needed. It;s known as the Elita model. The purpose of this research is to produce profile information about Elita's users who are categorized, in student's achievement and student's preferences in English for Mathematics lectures. This type of research is a mixture of qualitative and quantitative. Quantitative data were obtained from tests, and qualitative data were obtained from interviews and observations. The population is students of Mathematics Education, Universitas Negeri Padang. The sample was 43 students from January to June 2020 semesters. The instruments used were interview guides, field notes, and tests. The results obtained were the achievement of student's achievement in understanding the EFM lecture material, an increase in the average score, while the results of student’s preference in the EFM lecture process with the Elita model was moderate.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
