Abstract

This study aims to improve the problem-solving abilities of students of class VIII at SMP Negeri 10 Bandar Lampung, in learning mathematics using the Reciprocal Teaching learning model. This research is a Classroom Action Research (CAR). This action is carried out in 2 cycles where each cycle consists of 4 meetings. At each cycle, students are given a final cycle test to measure their problem solving abilities. Data analysis techniques in this research are descriptive analysis and quantitative analysis. The results showed that learning mathematics using the Reciprocal Teaching learning model can improve problem solving skills. This is indicated by an increase in the average value of the first cycle test of 57.40, while the second cycle test of 73.80. The average percentage of problem solving aspects in cycles I and II are as follows: (a) the ability to understand the problem increases from 50% to 75%, (b) the ability to plan problem solving increases from 62% to 77%, (c) the ability to carry out the plan increased from 59% to 70%, and (d) the ability to interpret the results obtained increased from 61% to 73%.

Practicality questionnaire to measure the response of class XI students at SMK Negeri 7 Bandar Lampung in product trials and learning achievement tests to measure the effectiveness of the module as teaching material. Material experts on the aspect of content quality obtain an average score of 3.66 on the aspect of determination of coverage get an average score of 3.75 on the Learning Cycle 5E aspect opinion average value of 3.8 with valid criteria. Media experts in the aspect of paper size in the module obtain an average value of 3.75, in the aspect of module skin design (cover) get an average value of 3.83, in the aspect of module content design get an average value of 3.87 with valid criteria .Linguists in the aspect of sentence structure determination, understanding of messages and straightforwardness get an average score of 4 with valid criteria. The mathematics module based on Learning Cycle 5E in Mathematical Logic material is effective in terms of student learning outcomes in Mathematical Logic material which shows 17 students or 56.67% individually completed out of 30 students with an average of 74.38. Thus the Learning Cycle 5E-based learning module is effective as a teaching material for learning mathematics.

Abstract

Mathematical problem solving ability is an important ability for students to have after learning mathematics, which is also one of the learning objectives. Learning in the Covid-19 pandemic situation also requires creativity for learning actors in equipping students with these abilities. This condition is the basis for research with the aim of analyzing the effect of the Problem Solving method on online learning on the mathematical problem solving abilities of eighth grade students of SMPIT Daarul 'Ilmi Bandar Lampung, with problems in the form of low mathematical problem solving abilities. This research method is a quasi-experimental method. Hypothesis testing using parametric statistics (t-test). The research was carried out in the odd semester of the 2021/2022 academic year with a population of all eighth grade students of SMPIT Daarul 'Ilmi Bandar Lampung. The sample was taken from 2 classes, namely class VIII F as the experimental class, totaling 28, and class VIII H as the control class, totaling 28. The sample was taken using the Cluster Random Sampling technique. Students' mathematical problem solving ability is measured by a test in the form of a description of 5 questions that have been tested for validity and reliability. The results of hypothesis testing show it can be concluded that there is an effect of the Problem Solving method on online learning on students' mathematical problem solving abilities. class VIII SMPIT Daarul 'Ilmi Bandar Lampung.

Abstract

The research is based on the problem of low mathematical communication skills of eighth grade students of SMP Negeri 3 Bandar Lampung. The use of learning models that do not meet the learning needs of students is one of the reasons for the low ability. Therefore, this study aims to analyze students' mathematical communication skills through the application of the SAVI learning model. This research is a quasi-experimental study, with a population of all eighth grade students. The samples were two classes, namely students of class VIII C as the experimental class, which amounted to 33 students and class VIII H as the control class, which amounted to 32 students. The sample was determined by the Cluster Random Sampling technique. Students' mathematical communication skills are measured by tests that have been tested for validity and reliability. Hypothesis test using t test. The results of the hypothesis test show that tcount > ttable, thus it is found that the average mathematical communication ability that applies the SAVI model is higher than those who apply the conventional model. It can be said that there is an effect of the application of the SAVI model on the mathematical communication skills of eighth grade students of SMP Negeri 3 Bandar Lampung.

Abstract

Society 5.0 requires the ability to think critically to deal with various changes. The ability to think critically in an era that emphasizes the role of humans as the center of civilization through the use of digital technology is not in line with the fact that the ability to think critically in class VIII odd semester students at SMP Negeri 26 Bandar Lampung in the 2022/2023 academic year. The ability to think critically mathematically in class VIII students is still a problem, for this reason this study aims to determine the effect of implementing the Open Ended approach on students' critical thinking ability in mathematics. This quasi-experimental study, with a population of all VIII grade students, totaling 227 students, while the samples were VIII E class as the experimental class and VIII G class as the control class. Samples were taken using the Cluster Random Sampling technique and to determine students' mathematical critical thinking skills were given a test in the form of a description of 5 questions which had previously been tested for validity and reliability. From the results of testing the hypothesis using the t test, the value of thitung = 3.35 is obtained. From the t distribution table at a significant level of 5% it is known that tdaftar = t(1-α) = 1.67. Thus thitung > tdaftar, so it can be concluded that the implementation of the Open Ended approach can affect the mathematical critical thinking skills of Grade VIII students in odd semesters at SMP Negeri 26 Bandar Lampung in the 2022/2023 academic year.
