Abstract

The purpose of this study was to determine the effect of different stages of geometric thinking in terms of understanding the concept of geometry and formative evaluation. The sampling technique used in this study was simple random sampling, so that a sample of 90 students. The research instrument is a test of the ability to understand geometric concepts, a geometric thinking level test and formative evaluation. The panelist test was carried out using the Aiken and Hoyt formula to determine the validity and consistency of the instrument, while the test was to determine the difficulty index, discriminating power, validity and reliability of the instrument. The data analysis technique used discriminant analysis. The results showed that (1) understanding of geometric concepts significantly affected the differences in students' geometric thinking level achievement, (2) formative evaluation significantly influenced students' geometric thinking level achievement differences, (3) discriminant function equation D = -11.743 + 0.0034X1 + 0.125 X2 to predict the achievement of geometric thinking level, (4) The percentage accuracy of the discriminant function equation in predicting the difference in the achievement of students' thinking level is 98.9%.

Abstract

This study aims to determine the Effectiveness of the Treffinger Learning Model in Improving the Ability to Understand Mathematical Concepts and Critical Thinking Skills of SMA Negeri 2 Bengkulu City Students in the even semester of the 2022/2023 academic year with the research population being all students of class XI, totaling 1,284 students and a research sample of 72 students consisting of 2 classes namely class XI MIPA U as the experimental class and class XI MIPA A as the control class. The research instrument is a test of understanding mathematical concepts and critical thinking skills. Data analysis was performed using the multivariate analysis of covariance (MANCOVA) test. The results showed that there was an influence of the Treffinger learning model on understanding mathematical concepts and critical thinking skills together at 78.7%. Furthermore, the effect of the Treffinger learning model on understanding mathematical concepts is 72.3% and the influence of the Treffinger learning model on critical thinking skills is 78.6%. The average score of students in the class taught by the Treffinger learning model is higher than that of students taught by using the Scientific learning model. The average understanding of mathematical concepts in the experimental class was 80.667 and the control class was 62.5. The average critical thinking ability in the experimental class was 78.13 and in the control class was 58.76

Abstract

This study aims to determine the effect of the Intruction Connection Application Reflection and Extention (ICARE) Learning Model on Students' Problem-Solving Ability and Critical Thinking Ability. This type of research uses the Quasi Experiment method. Data collection is done through tests. Data analysis used the Ancova test. The sample of this study were students of SMPIT Darul Fikri Bengkulu Utara grades VII A and VII B. The results showed that: 1) There was a linear covariate effect of initial ability on problem solving ability with a significant influence of 50.3%. 2) There is a linear influence of the initial ability covariate on critical thinking skills with a large influence of 56.7%. 3) There is an effect of learning using the ICARE model on students' problem-solving abilities with a large influence of 59.9%. 4) There is an influence of learning using the ICARE model on students' critical thinking skills with a large influence of 59.4%.

Abstract

This research aims to determine the effect of online learning (Google Classroom) using a scientific approach based on ethnomathematics on the mathematical problem solving and communication abilities of class VIII students at SMPN 02 Bengkulu City. This research is quantitative research with a quasi-experimental method. The population in this study were class VIII students at SMPN 02 Bengkulu City, Even Semester, 2020/2021 Academic Year. The sample for this research was class VIII C students as an experimental class by implementing online learning (Google Classroom) using an ethnomathematics-based scientific approach to mathematical problem solving and communication skills and class VIII A students as a control class by applying conventional learning via WhatsApp. The results of this research show that the Ftable value = 3.99. The results of learning using online (Google Classroom) with conventional learning on problem solving abilities Fcount = 7.9. The results of the problem-solving abilities of students with high abilities and students with low abilities Fcount = 8.86, and the results of the interaction of learning factors and abilities on students' problem-solving abilities Fcount = 7.41. It can be concluded that Fcount > Ftable, then H0 is rejected, so there is an influence of online learning (Google Classroom) using a scientific approach based on ethnomathematics on the problem-solving abilities of class VIII students at SMPN 02 Bengkulu City
