The problem of this research was the low ability of grade V elementary students’ mathematics problem solving in Baitul Jannah Islamic elementary school. The objective of this research was to analyze the average of students’ mathematics problem solving abilities by using GeoGebra media and by using conventional learning. This was an experimental research. Population was all grade V students in classrooms V.A with GeoGebra learning for experiment and classroom V.B with conventional learning for control in Baitul Jannah Islamic elementary school. Students were given with five mathematics test problems in essay that had been tested for their validities and reliabilities. Data were analyzed by using t-test. The result showed that the average of students’ mathematics problem solving who used GeoGebra learning were higher compared to those with conventional learning.
The objectives of research were to find out: 1) which one providing better mathematics learning achievement, TTW by using talking stick model, TPS by using talking stick model or classical learning model, 2) which one providing better mathematics learning achievement, linguistic intelligence, mathematics logic intelligence or interpersonal intelligence, 3) in each multiple intelligence level, which one providing better mathematics learning achievement, TTW by using talking stick model, TPS by using talking stick model or classical learning model, and 4) in each learning models, which one providing better mathematics learning achievement, linguistic intelligence, mathematicslogic intelligence or interpersonal intelligence. This research used the quasi experimental research method. The design of the research was 3 × 3 factorial. The population was the students of the seven class of Junior High School in Surakarta City on academic year 2014/2015. The tecnique of sampling was stratified cluster random sampling. The proposed hypothesis of the research were tested by using the unbalanced two-way analysis of variance.The conclusions of this research were as follows: 1) TTW by using talking stick model provided better mathematics achievement than TPS by using talking stick model and classical learning model. 2) the mathematics logic intelligence students had mathematics achievement better than linguistic intelligence, the mathematics achievement of linguistic intelligence is the same as interpersonal intelligence, and the mathematics logic intelligence students had mathematics achievement better than interpersonal intelligence. 3) in each of multiple intelligence categories, students mathematics learning achievement is in constancy with result of learning models.4) in each learning models, the students mathematics learning achievement is in constancy with result of multiple intelligence categories.
Word problems are the most important thing in learning in Indonesia. Most of the students met the problems. This research aims to enhance the students’ability in the difficulties of students in solving word problems in social arithmetic. This research is qualitative. Researchers collected data through tests, interviews, and documentation. Data analysis techniques included data collection, data reduction, display (data), and concluding. The results showed that the difficulties in solving word problems in social arithmetic were difficulties in understanding the problems, namely the inability of students to translate the problem that is not able write down what is known and asked; difficulties in transformation, i.e. the inability of students to determine the formula for solving arithmetic problems social; difficulties in the settlement process, namely the inability of students in students perform arithmetic operations to solve the social arithmetic problem. Factors which causes students difficulty that is lazy to read too long questions, difficult to digest words in a problem, lack of student interest in learning mathematics, a way of learning for students who tend to memorize the material so the concept does not clear, students rarely practice the questions, do not understand the counting operations well, motivation low learning, a less conducive classroom, and learning strategies.
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.
