Abstract

Critical thinking ability is a basic ability that is very important to master, this is because critical thinking is an important component in higher level thinking. Students' low ability to understand mathematical concepts is caused by the use of teaching materials that are less than optimal in applying mathematical concepts. Efforts to overcome the problem of students' low critical thinking abilities require developing teaching materials in the form of Student Activity Sheets (LKS). This is what triggered researchers to carry out research aimed at developing live worksheets to improve students' critical thinking skills at SMP Negeri 1 Sarang. The type of research used is Research and Development (R&D) using the 4D model. The research subjects were class VII junior high school students with data collection instruments in the form of questionnaires, interviews, observations, documentation. The data analysis techniques used in this research are qualitative and quantitative data analysis techniques. The validation results showed that the LKS met the valid criteria with a percentage of 92%. The practical results showed that the LKS met the practical criteria with a percentage of 82.25%. The effectiveness results showed that the LKS met the effective criteria, namely that 80% of students had a score of more than or equal to 75. Based on the research results, it could be concluded that the live worksheet-based LKS to improve students' critical thinking skills in social arithmetic material was valid, practical and effective.

The data will be analyzed and used to explain the problem being studied. The results of data analysis show that students experience various difficulties in understanding the basic concepts of fractions and the ability to calculate fractions. One of the biggest difficulties is understanding the relationship between the numerator and denominator of a fraction. Students also often have difficulty converting fractions into their simplest form, changing fractions from mixed fractions to improper fractions and vice versa. Apart from that, understanding fractions with different denominators is also a challenge for students. The conclusion of this research is that elementary school students face many different difficulties when solving fraction calculation problems. These difficulties include understanding the basic concepts of fractions, changing the form of fractions, calculating the results of multiplying or dividing fractions, simplifying fractions, and applying fractions in the context of everyday situations

Abstract

The education dharma program states that lecturers have the main task of administering education. Permenristekdikti No. 44 of 2015 states the minimum criteria for the learning process, namely CPL (Graduate Learning Outcomes). CPL requires student-centered learning and the role of the lecturer as a facilitator so that Student Center Learning (SCL) is created. Real Analysis 2 which is a follow-up course from Real Analysis 1. Real Analysis 2 is a pure mathematics course that contains a collection of definitions and theorems and lemmas that involve proof. So far, learning real analysis is difficult for students to accept, namely making connections between one rule and another. One learning model that facilitates students to fulfill the CPL for Real Analysis 2 course is the PjBL (Project Based Learning) model. PjBL implementation must be supported by adequate learning facilities. Therefore, a module based on the PjBL model is needed. The use of this PjbL-based module is expected that students will be able to solve mathematical problems and support the fulfillment of CPL courses which results in the formation of creative and systematic mathematics students who are good at solving problems and have the capabilities and competencies needed by the world of work.

Abstract

Monotonous and conventional learning using the lecture method can cause students to be less interested in learning. This causes the concept given not to imprint sharply in the memory of students so that students easily forget and often confused in solving a problem that is different from what is exemplified by the teacher. The purpose of this study is for the feasibility, effectiveness, and development of snakes and ladders media with a Realistic Mathematics Education model on understanding mathematical concepts. In this study, research and development (R&D) research methods were used. This research will be carried out in grade IV SDN Tambirejo with research subjects of 10 students and teachers. The subject selection of 10 students was obtained from the postest and prettest assessments. For teachers, an assessment was obtained from the results of interviews between researchers and teachers. The dependent variable in this study is understanding the concept, while the independent variable is a Realistic Mathematics Education model assisted by two snakes and ladders. Data collection techniques include interviews, observations, tests, and documentation. The data analysis used is qualitative and quantitative data analysis. The results of this study show that Snakes and Ladders media is very feasible to use, shown by the percentage of media feasibility of 77% and material feasibility of 88%. The N-Gain test showed a result of 0.1785 with the "medium" category. The conclusion in this study is that the Snakes and Ladders media is declared feasible and effective for use in grade IV learning of Wide Material Maematics Lessons and flat build circumference.
