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%.

Abstract

The Corona outbreak has made everything change routine, including in terms of education. In the past, learning in universities was carried out face-to-face, but now learning must be carried out online. The purpose of this study was to find out how much effective online learning was during the COVID-19 pandemic for students. This study uses an exploratory descriptive approach in the scope of qualitative research. The research subjects were active students of the mathematics education study program STKIP PGRI Bandar Lampung semester 2 and 4 of the 2020/2021 academic year. The research data was obtained by using a questionnaire in the form of a google form which was filled in by the 2 and 4 semester students via a smartphone or laptop. The data obtained were analyzed descriptively, starting with grouping based on the category of responses, then describing the different responses from students. This study found obstacles in the online learning process, namely students' economic problems that could affect the ownership of mobile phones as the main support for online learning, constraints on internet packages or wifi networks, and poor networks in the student environment. The results of the research can be concluded that online learning is not effective.

Abstract

This study aims to analyze and describe the problem-solving abilities of junior high school students on similarity material with the Problem Solving learning model. This research is a qualitative descriptive study. The subjects of this study were 27 children. Samples of class students at SMP Negeri 45 Bandar Lampung. The method used to collect data is to use written worksheets with mathematical problem solving skills on congruence material. The results showed that the mathematical problem solving abilities of class IX students of SMP Negeri 45 Bandar Lampung were already high. Judging from the presentation, it was stated that students were able to identify known elements, apply strategies and develop mathematical models. Overall, students' mathematical problem-solving abilities, especially in congruence material, are in high qualification, although there are some students who are still in low qualification.

Abstract

This study aims to analyze and determine the effectiveness of the TTW (Think Talk Write) learning model on the mathematical problem solving abilities of SD Negeri 2 Penengahan Bandar Lampung students. This research is an experimental research. The study population consisted of all students of class SD Negeri 2 Penengahan Bandar Lampung consisting of 5 classes with a total of 120 students, while 2 classes were taken as samples, namely class V A as the experimental class which consisted of 32 students, and class V C as the control class which consisted of 30 students. The sample was taken using the Cluster Random Sampling technique. Students' mathematical problem solving abilities were measured by a test in the form of an essay of 5 questions which had previously been tested for validity and reliability. From the results of testing the hypothesis using the statistical formula t-test, the value of thit = 2.15 was obtained. From the t distribution table at a significant level of 5%, it is known that tdaf=1.67 means thit>tdaf, namely 2.15>1.68, so it can be concluded that "TTW (Think Talk Write) Learning Model is Effective for the mathematical problem solving abilities of SD Negeri 2 Penengahan students Bandar Lampung. This situation can also be seen from the average value of students' mathematical problem solving abilities where the experimental class has an average value of 78.94 higher than the control class has an average value of 60.69
