Abstract

: This study aims to determine the effect of the Problem Based Learning (PBL) model on students’ mathematical problem solving abilities in matrix material in the SMA XI IPA Gajah Mada Bandar Lampung High School 2018-2019. This research is quantitative research with a type of quasi-experimental research. The population is all students of class XI IPA in Gajah Mada High School 2018-2019 which number 96 students and sampling using cluster random sampling. The test instrument used to determine students' problem solving abilities is to use a description test. The results of data analysis at the pretest of the experimental class showed that students' mathematical problem solving abilities were still relatively low with an average score of 58,81 and in the control class an average score of 58,81. The results of data analysis on the experimental class posttest showed that students' mathematical problem solving abilities increased with an average value of 78,18 whereas in the control class an average score of 70,18. Based on the t test performed t_count> t_table is10,66.> 1,69 which means that there is a significant effect of the Problem Based Learning model on students' mathematical problem solving abilities in the matrix material in Gajah Mada High School Bandar Lampung XI class 2018-2019

Abstract

The problems studied in this study relate to the less than optimal achievement of students' mathematics learning outcomes. The purpose of this study was to determine the effect of the Numbered Head Together learning model on mathematics learning outcomes for grade VIII Odd Semester students of SMP Negeri 27 Bandar Lampung in the 2021/2022 academic year. This study used an experimental method with the population in this study, namely all eighth grade students of SMP Negeri 27 Bandar Lampung which consisted of 8 classes with a total of 242 students. Meanwhile, two classes were taken as samples, namely class VIII A as the experimental class that applied the Numbered Head Together learning model, and class VIII E as the control class that applied the conventional learning model. Samples were taken using cluster random sampling technique. To find out the students' mathematics learning outcomes, the author conducted a test in the form of an essay as many as 10 questions which had been tested for validity and reliability. Hypothesis testing in this study uses the t-hit formula. From the results of hypothesis testing using the t-hit statistical formula, the value of t = 2,93 is obtained. From the t distribution table at a significant level of 5%, it is known that t = 1,67 then  which means that the average mathematics learning outcomes of students who use the Numbered Head Together learning model are higher than the average mathematics learning outcomes of students who use the model. conventional learning.

Abstract

The problems studied in this study are related to the low mathematical problem solving ability of students. The purpose of this study was to determine the effect of the use of learning videos on the mathematical problem solving abilities of eighth graders in odd semesters at SMP Negeri 14 Bandar Lampung in the academic year 2022/2023. This study used an experimental method with the population in this study, namely all students of class VIII Odd Semester SMP Negeri 14 Bandar Lampung, while the sample was taken two classes, namely class VIII B as an experimental class that used video learning, and class VIII C as a control class that did not use learning videos. learning video. Samples were taken using the Cluster Random Sampling technique. To determine the students' mathematical problem solving ability, the author conducted a test in the form of an essay as many as five questions which had been tested for validity and reliability. Hypothesis testing in this study uses the t-hit formula. From the results of hypothesis testing using the t-hit statistical formula, the value of t = 3,07 is obtained. From the t distribution table at a significant level of 5%, it is known that t = 1,67 then  which means that the average mathematical problem solving ability of students who use learning videos is higher than the average mathematical problem solving ability of students who do not use learning videos.

Abstract

The problem in this study is the low critical thinking skills of students in learning mathematics. The purpose of this study was to determine the effect of applying a realistic mathematical approach to the critical thinking skills of Class X Even Semester students at SMK Negeri 7 Bandar Lampung in the 2022/2023 academic year. This study used an experimental method with the population in this study, namely all students in class X even semester of SMK Negeri 7 Bandar Lampung, while two classes were taken, namely class X KK 1 which used a realistic mathematics approach, and class X KK 2 which used a conventional approach. Samples were taken using the Cluster Random Sampling technique. To find out students' critical thinking skills, a test was carried out in the form of an essay of five questions which had previously been tested for validity and reliability. Hypothesis testing in this study uses the t-hit formula. From the results of testing the hypothesis using the t-hit statistical formula, the value of t = 1,88 is obtained. From the t distribution table at a significant level of 5% it is known that t = 1,67 then  which means that the average critical thinking ability of students who use a realistic mathematics approach is higher than the average critical thinking ability of students who use a conventional approach.

Abstract

This study aims to investigate the effectiveness of the use of technology-based learning media, including mobile applications, learning videos, and software such as GeoGebra and Matlab, in improving the understanding of mathematical concepts of high school students. Through a quantitative approach, with an experimental design, this study involved 90 students from SMA 8 Bandar Lampung who were divided into 3 groups. Data analysis was carried out using t-test to compare the level of understanding of students before and after the use of learning media. The results showed that there was a significant improvement in students' understanding of mathematical concepts after the use of technology-based learning media (p < 0.05). GeoGebra was shown to provide the best results with an increase in understanding by 48.5%, followed by mobile applications (40.2%) and learning videos (30.1%). These findings indicate that the use of technology-based learning media is effective in improving students' understanding of mathematical concepts.
