Abstract

Factors that affect students' mathematics learning outcomes include the lack of student interest in mathematics. Learning that does not have meaning and the teacher's teaching methods are still less diverse, causing a lack of student interest in learning mathematics. One of the meaningful learning is when students can make their own notes from their understanding while studying. This study aims to determine the differences in mathematics learning outcomes of students who are taught using the mind map method and students who are taught with the concept map method. This research was conducted at a private senior high school in Medan. This type of research is a quasi-experimental research design using randomize pretest-posttest control group design. The sampling technique uses purposive sampling by taking two experimental classes in class X high school. The instrument used to determine student learning outcomes on exponent material is a test in the form of an objective test of 15 items that have been declared valid and reliable. The results showed that the average student learning outcomes taught using the mind map method were higher than those taught with the concept map. From the results of this study teachers are expected to use the mind map method to improve student mathematics learning.

Abstract

From the results of observations at MTsN 10 Padang Pariaman, it is known that students need LKPD that facilitates their mathematical communication skills. The required LKPD needs to be supported by an appropriate learning model. The Group Investigation model was chosen because it fits the characteristics of the problems in MTsN 10 and is suitable for collaboration with LKPD. This study aims to produce LKPD based on the Group Investigation model to improve valid, practical and effective mathematical communication skills. This research is a development research conducted with reference to the first 3 stages of the 4D model with the following stages: (1) define, (2) design, (3) develop. Practical trials were conducted on 12 students of MTsN 10 Padang Pariaman. The results of this study indicate that the developed mathematics worksheets meet the valid criteria with an average value of 84.9%. The developed math worksheets meet the practical criteria with an average score of 87.3% for educators and 84.6% for students. The developed math worksheets also meet the effective criteria with an average score of 88%. The effectiveness of the development of LKPD based on Group investigation is seen based on the completeness of the results of the Mathematical Communication Ability test that came from 12 students. Based on these results, it can be concluded that the development of LKPD based on the Group Investigation model is in the valid, practical, and effective categories so that it is suitable for use in the learning process and can improve students' mathematical communication skills.

Abstract

This study aims to predict the population of the province of East Nusa Tenggara by applying the Interpolation method. The research method used is the method of literature study and computer programming simulation MATLAB and Exel. Data were obtained from the Central Statistics Agency (BPS) from 1971, 1980, 1990, 1995, 2000, and 2010. Knowledge of population development each year would be difficult to know if the population census was only conducted once every ten years. Therefore, an alternative mathematics that can be used as a reference for solving the problem of population size each year is numerical forecasting, namely the interpolation method. By using the Lagrange interpolation method, it is found that every year the population increases by an average of 2.107%. The solution expected from this research is the existence of government programs that can reduce the birth rate and reduce the number of transmigrants.
