Abstract

This study aims to produce a valid, practical, and effective problem posing learning model-based learning tool for Class VIII students of SMP Nusantara Lubuk Pakam, to analyze the improvement of students' mathematical communication skills taught with learning tools developed based on the Problem Posing Learning model in SMP. Nusantara Lubuk Pakam, to analyze the achievement of student learning independence taught with learning tools developed based on the Problem Posing Learning model at SMP Nusantara Lubuk Pakam, as well as to analyze the answer process of SMP Nusantara Lubuk Pakam students in solving test questions of mathematical mathematical communication skills. The data were obtained through the validation sheet of teaching materials, observation sheets, student response questionnaires, mathematical communication skills test instruments and student learning independence questionnaires. This study uses the 4-D development model Thiagarajan, Semmel and Semmel by developing teaching materials with problem posing learning. Based on the validation results of the value of learning tools developed through the Problem Posing learning model, the validator team met the valid and practical criteria. The implementation of the learning tools developed through the Problem Posing learning model was in good criteria, namely 87.78% in trial II. Classical mastery of student learning has been achieved in the second trial by 90%. The achievement of learning objectives has been achieved in the second trial, which is 83.39%. Student responses to components and learning activities 94.11% have shown a positive response to the components of learning tools and learning activities developed.

Abstract

This study aims to analyze the validity and effectiveness of teaching materials developed based on a realistic mathematical approach in improving students 'mathematical reasoning and representation abilities, to analyze the increase in students' reasoning skills and mathematical representation abilities taught using teaching materials based on realistic mathematical approaches. The data were obtained through the validation sheet of teaching materials, observation sheets, student response questionnaires, mathematical reasoning ability test instruments and mathematical representation ability tests. This study uses a 4-D development model Thiagarajan, Semmel and Semmel by developing teaching materials with a realistic mathematical approach. Based on the results of the validation, the total average value of the RPP validity was 4.81, the student books were 4.83 and the LKPD was 4.85, the students' mathematical reasoning ability tests and the mathematical representation ability tests were in the valid category. Classical mastery of learning reaches 90.62% which has met the completeness criteria, namely ≥85% of students have reached the KKM. The increase in students' mathematical reasoning abilities using teaching materials based on a realistic mathematical approach on fraction material seen from N-Gain in the first trial and second trial has increased from 0.36 to 0.50 meaning that it is in the medium category. As well as an increase in the ability of students' mathematical representation using teaching materials based on a realistic mathematical approach on fraction material seen from N-Gain in the first trial and second trial, it increased from 0.43 to 0.50, meaning that it was in the medium category.

Abstract

This study aims to determine the validity, practicality and effectiveness of the developed teaching materials, as well as to determine the improvement of students' critical thinking skills using the developed teaching materials. Data obtained through the validation sheet of teaching materials, observation sheets, student response questionnaires, and critical thinking skills test instruments. This study uses the 4-D development model Thiagarajan, Semmel and Semmel (1974) by developing mathematics teaching materials with a realistic mathematics approach. Based on the results of the validity of the learning tools developed, it was included in the valid category with an average value of the total validity of students' books of 4.50, LKPD of 4.62 and the critical thinking ability test in the valid category. The effectiveness of learning devices that meet the effective criteria with the achievement of student learning completeness with a classical completeness percentage of 86.1%., Active student activities meet the ideal time tolerance criteria set, and student responses to learning devices are in good categories. And the average increase in students' critical thinking skills from trial I to trial II was 0.34 points with an increase in classical learning completeness of 17.35%.

Abstract

This study aims to determine: (1) The effect of the ethnomatematics-based RME approach on improving the understanding of the fourth grade students' mathematical conceptual understanding of Al-Kausar Elementary School Langsa City, (2) The effect of the ethnomatematics-based RME approach on increasing the learning motivation of fourth grade students of SD Al-Kausar Kota Langsa, (3) There is an interaction between the learning approach and the initial mathematical ability to increase the students' understanding of mathematical concepts in grade IV SD Al-Kausar, Langsa City, (4) There is an interaction between the learning approach and learning motivation towards the increase in the ability to understand the mathematical concepts of fourth grade students Al-Kausar Kota Langsa, and (5) Describing students' ability to understand mathematical concepts in terms of high, medium and low abilities. The sample in this study was selected by total sampling of two classes. The first class (first group) was treated by applying the RME approach based on ethnomatics with a sample size of 25 students and the second class (second group) was treated with conventional learning with a sample size of 25 students. The data in this study were analyzed using 2-way ANOVA. From the research results, it is obtained that there is an effect of the ethnomatematic based RME approach on the improvement of students 'understanding of mathematical concepts, where as much as 47% of the ethnomatematic based RME approach affects the increase in students' understanding of mathematical concepts.This study aims to determine: (1) The effect of the ethnomatematics-based RME approach on improving the understanding of the fourth grade students' mathematical conceptual understanding of Al-Kausar Elementary School Langsa City, (2) The effect of the ethnomatematics-based RME approach on increasing the learning motivation of fourth grade students of SD Al-Kausar Kota Langsa, (3) There is an interaction between the learning approach and the initial mathematical ability to increase the students' understanding of mathematical concepts in grade IV SD Al-Kausar, Langsa City, (4) There is an interaction between the learning approach and learning motivation towards the increase in the ability to understand the mathematical concepts of fourth grade students Al-Kausar Kota Langsa, and (5) Describing students' ability to understand mathematical concepts in terms of high, medium and low abilities.

Abstract

In fact, the implementation of the teaching-learning process does not train and develop students' communication skills to cause interaction between students, such as working together, expressing ideas, asking questions, and responding to questions / opinions of other students. The teachers have applied the discussion learning model, but this is done with a direct learning model. During the discussion, the teacher only gives a number of assignments to students which contain almost all of the material without giving instructions, so that the students' thinking patterns do not develop and are not stimulated to think critically. This research was conducted at SD Negeri No.030277 Teladan Sidikalang, Sidikalang District, Dairi Regency. The population in this study was all fifth grade students of SD Negeri No.030277 Teladan Sidikalang which consisted of 3 classes totaling 91 students. Class VA as many as 31 students, class VB as many as 30 students, and class V-C as many as 30 students. There is a significant influence between learning (guided discovery learning and direct learning) on students' mathematical communication skills. The effect of the independent variable on changes in the dependent variable is 31.2%, while the remaining 68.8% is influenced by other variables. There is a significant influence between learning (guided discovery learning and direct learning) on students' self confidence. The effect of independent variables on variable changes is 9.6%, while the remaining 90.4% is influenced by other variables.
