Abstract

The population growth rate of an area is influenced by several factors including fertility, mortality and migration. Meanwhile, population counts are usually carried out through a population census which is carried out every 10 years. As a metropolitan area, every year North Sumatra experiences a very rapid population growth rate. The population growth rate can be modelled with a stochastic model. In stochastic modelling refers to the percentage calculations for fertility, mortality and migration in predicting for the next census year period. Meanwhile, to calculate the population, you can use numerical methods, namely, forward newton Gregory polynomial and reverse newton Gregory polynomial. The method used in this study is a literature study where the data source used is secondary data and in this case, the researcher analyzes between three census periods, namely the period 1980 to 2010 and then predicts the period of the next census year. The purpose of this study was to determine the effectiveness of the three models in predicting the population of North Sumatra in the census period. For stochastic modelling, the prediction results obtained for the year 2010 are the percentage of total birth rate or fertility reaching ± 17.67%, the mortality reaches ± 39.61% and the migration reaches ± 42.72%. For 2020, the probability that the percentage of total birth or fertility is ± 16.83%, the mortality is ± 33.85% and the migration is ± 49.36% and for 2030 the probability of the percentage of total birth or fertility is ± 16.98%. the mortality reached ± 34.28% and the migration reached ± 48.74%. And for the forward newton Gregory polynomial method and the reverse Gregory newton polynomial, the total relative error is obtained respectively while for the reverse newton Gregory polynomial method the total error value is. Referring to the error value, the advanced Newton Gregory polynomial method has better accuracy.

Abstract

To find out the increase in the ability of mathematical understanding in learning calculus I semester II students of mathematics education study programs on the subject of functions and limits, we need a learning media in the form of Geogebra applications. Geogebra applications is one of the calculus I learning media that can be used to demonstrate or visualize mathematical concepts as well as a tool to construct concepts mathematically. The sample in this study was 54 seconds semester students of the mathematics education study program, Faculty of Education, University of Timor using purposive sampling techniques. The method used in this study is a pre-experimental method with one group pretest-posttest design. Analysis of the data in this study used the non-parametric Mann Whitney test. Based on the results of the N-gain score test, it shows that the average N-gain score is 58.4251 or 58.4%, which results are included in the quite effective category. Thus, the use of Geogebra applications in learning calculus I in the second-semester students of mathematics education study programs is quite effective in improving students' mathematical understanding of learning calculus I.

Abstract

This study aims to determine the influence of parental attention and learning motivation on mathematics learning outcomes of seventh-grade students of SMP Negeri 1 Pematangsiantar. Parental attention and learning motivation data obtained from an instrument in the form of a closed questionnaire distributed online via google form with good quality because it is valid and reliable. Meanwhile, students' mathematics learning outcomes were obtained from the school's documentation of grades. The test results show that there is a direct effect of parental attention on learning motivation with a t-count of 2.1309 and a significance level of 0.08325; there is a direct effect of parental attention on student mathematics learning outcomes with a t-count of 2.42875 and a significance level of 0.13768; there is an indirect effect of learning motivation on student mathematics learning outcomes with a t-count of 2.58298 and a significance level of 0.14988; there is an indirect effect of parental attention and learning motivation on mathematics learning outcomes. As for the contribution given by parents' attention and learning motivation to mathematics learning outcomes was 28.75% and the total effect was 42.327%. Therefore, the higher parental attention and student motivation, the higher the learning outcomes.

Abstract

The purpose of this study was to determine the contribution of the guided inquiry learning model to the reasoning ability of students. This research is a quasi-experimental study using two groups of samples (experimental and control) that have been declared normal and homogeneous. The study was conducted at SMP Negeri 27 Medan in 8th-grade students with two classes sample, each class with 40 students. The instrument used was in the form of a reasoning ability test consisting of pretest questions (6 items) and posttests (3 items) which have been declared valid and reliable. The results showed that in the guided inquiry class, students 'reasoning ability was influenced by the KAM value of 66%, while in the expository class, students' reasoning ability was influenced by the KAM value of 71.3%. This shows that the contribution of KAM in the guided inquiry class is smaller than the contribution of KAM in the expository class on reasoning ability (66% 71.3%).
