Abstract

This research was motivated by the common mathematical problem-solving ability of class XII MIPA students at SMAN 1 Lubuklinggau. Problem-solving at school is an ability that must be mastered so that students can lead to understanding mathematics. This study aims to determine (1) the mathematical problem-solving skills of students participating in Edmodo-based online learning and (2) the improvement of students' mathematical problem-solving abilities after being treated with Edmodo-based online learning. 2020/2021 with a total of 36 students. Classroom Action Research Procedures was carried out through four stages, namely: (1) Planning, (2) Implementation, (3) Observation, and (4) Reflection. Research data was collected by test and observation techniques. Data analysis was carried out by comparing test results and observation data with the formulated indicators of success. Based on the results of data analysis, it can be concluded that, Edmodo-based online learning can improve the mathematical problem-solving abilities of class XII MIPA 7 students of SMA Negeri 1 Lubuklinggau. The average value of mathematical problem-solving abilities from the first cycle of 62.2 increased in the second cycle to 77.3. The percentage of learning completeness also increased from the process I by 52.8% and in cycle II by 80.6%. The rate of students' mathematical problem-solving ability increased after being given action was 23.67%. The interpretation of students' problem-solving abilities in the material on Limits of Trigonometry Functions after being given an Edmodo-based online learning activity is included in the good category.

Abstract

The problem in this study is the low ability of students' mathematical problemsolving in learning mathematics. The purpose of this study was to determine the effectof applying the contextual teaching and learning approach to the mathematicalproblem solving abilities of Grade VIII students in odd semesters of SMP Negeri 34Bandar Lampung in the 2022/2023 academic year. This study used an experimentalmethod with the population in this study, namely all students of class VIII Odd SemesterSMP Negeri 34 Bandar Lampung, while two classes were taken as samples, namelyclass VIII B which used a contextual teaching and learning approach, and class VIII Awhich used a conventional approach. Samples were taken using the Cluster RandomSampling technique. To find out students' mathematical problem solving abilities, a testwas carried out in the form of an essay of five questions which had previously beentested 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 valueof t hit = 2.60 is obtained. From the t distribution table at a significant level of 5% it isknown that t daf = 1.67, then t hit > t daf , which means that the average mathematicalproblem solving ability of students using the contextual teaching and learningapproach is higher than the average mathematical problem solving ability of studentsusing the conventional.

Abstract

The problem in this study is the low ability of students' mathematical communication in learning. The purpose of this study was to determine the effect of using android-based learning media on the mathematical communication abilities of Class VIII students in Odd Semesters of SMP Negeri 13 Bandar Lampung in the Academic Year 2022/2023. This study used an experimental method with the population in this study, namely all students in class VIII Odd Semester SMP Negeri 13 Bandar Lampung. The samples used in this study were two classes, namely class VIII-4 as the experimental class, and class VIII-3 as the control class. Samples were taken using the Cluster Random Sampling technique. To find out students' mathematical communication 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_hit = 4.04 is obtained. From the t distribution table at a significant level of 5% it is known that t_daf = 1.67, then t_hit>t_daf, which means that the average mathematical communication ability of students using Android-based learning media is higher than the average mathematical communication ability of students using conventional approaches.

Abstract

This quasi-experimental research aims to determine the increase in the ability to understand students' mathematical concepts by implementing the discovery learning model. The population of this study were all Grade VIII students in the even semester of Tri Sukses Natar Middle School for the 2022/2023 academic year, totaling 94 students and distributed in four classes. The research sample was class IIC and VIIID students who were taken by purposive sampling with a pretest-posttest control group design. The research data was obtained through a concept understanding test in the form of an essay. Data analysis in this study used a t-test. Based on the results of the research and discussion, it is concluded that the implementation of the discovery learning model can improve students' understanding of mathematical concepts.

Abstract

The ability to think creatively is an important ability to be provided to students starting from the elementary school level in the revolutionary era that demands creativity in all things, but this ability has not been fully mastered by elementary school students. This study aims to analyze the creative thinking skills of elementary school students through the application of the Picture and Picture active learning model in the fifth grade of SD Al Azhar 1 Bandar Lampung. The study used an experimental method with the research population of all fifth grade students of SD Al Azhar 1 Bandar Lampung and a sample of 2 classes. The sample was taken using the Cluster Random Sampling technique. The ability to think creatively in mathematics is measured by a test in the form of an essay as many as 4 questions which are first tested for validity and reliability. Hypothesis testing using t-test, obtained t-hitung = 6.92. From the t distribution table at a significant level of 5%, it is known that t-daf = 1.99, which means that t-hit > t-daf is 6.92 > 1.99, so it can be concluded that the mathematical creative thinking ability of fifth graders at SD Al Azhar 1 Bandar Lampung can be influenced through the application of the Picture and Picture active learning model, this can be seen from the average mathematical creative thinking ability of students who apply the Picture and Picture learning model is not the same as the average mathematical creative thinking ability of students who use conventional learning models namely 80.11 and 52.61.
