Abstract

This article discusses the results of research on the application of sequences and series material in economic mathematics to population growth models. Material sequences and series are often used by experts in solving problems related to socio-economics. The purpose of this study was to determine student responses when learning sequences and series in economic mathematics to population growth models, to determine the effectiveness of student knowledge during learning sequences and series material in their understanding of population growth model material. The research method used is quasi-experimental, with a quantitative approach. The population of this study were all students of the Mathematics Education study program and the sample was students of the Mathematics Education study program for the fifth semester Mathematics Economics course at Indraprasta University PGRI which consisted of one class. The research instrument used was observation of student activities to find out the process of learning the material for sequences and series in economic mathematics on population growth models, interviews and filling out Likert-scale questionnaires. Based on an analysis of the completed questionnaire, students responded positively in learning the material for sequences and series in economic mathematics to population growth models. And based on the results of the questionnaire it is known that the learning material for sequences and series is effective in learning population growth models in economic mathematics.

Abstract

The research was conducted to determine students' ability to solve problems with matrix material. This study used descriptive qualitative research and took 20 class XI students of SMK Bina Bangsa as research objects. The techniques used to collect research data are 3 instruments in the form of question descriptions and questionnaire forms. Data analysis in this study used data reduction, data presentation, and drawing conclusions. As a result of this study, students of class XI at SMK Bina Bangsa did not do well in mastering the matrix material and understanding the concepts. The reason students find it difficult to master matrix concepts is because students do not have the necessary material such as fraction operations and negative number operations. The lack of practice questions is also a factor in students' lack of understanding of the determinants of matrices.
