Abstract

The purpose of this study is to determine the level of student thinking based on gender differences by exploring students 'geometrical thinking abilities and creating learning examples to improve students' level of thinking. While the differences in mathematical abilities are high, medium and low mathematical abilities. This type of research is exploratory research using a naturalistic qualitative approach, by taking 3 male students and 3 female students as research subjects which are then grouped based on mathematical abilities. The results of each activity are analyzed and the level of thinking of each research subject is determined. All subjects still ignored class inclusion of quadrilateral shapes even though they were able to distinguish geometric shapes based on the properties of the components. the sequence of learning phases revealed by van Hiele, namely: (1) Information Phase (Information), (2) Guided Orientation Phase, (3) Explicitation Phase, (4) Free Orientation Phase Orientation), and (5) Integration Phase. The results obtained are that both male and female students are at the level of thinking 1. It is different from the difference in students' level of thinking when viewed from their mathematical abilities. For students who are in the high and medium grades, all students are at level 1 thinking, whereas in the low value group only one student is at level 1 thinking and the others are at level 0 thinking. While the learning examples made are Learning Implementation Plans (RPP) and Student Worksheets (LKS) are made with the hope of increasing the level of van Hiele students' geometry thinking from level 1 to level 2.

Abstract

The process of learning mathematics still uses conventional methods where the teacher dominates the learning process, so still experience learning difficulties, especially understanding concepts and mastery of geometry which causes learning outcomes to decline. This causes students to be passive and only accept the teacher's explanation in other words students are not directed to think to find solutions to the problems at hand. Problem-based learning is learning that makes students active and can find their concepts and be more effective. In addition to problem-based learning. learning must use media that support a more effective teaching and learning process. The use of teaching aids is very influential on the success of the teaching and learning process. The type of this research is experimental research and quantitative approach. The population in this study were all students of class VII SMP Rewarangga while the sample was taken by random sampling totaling 14 students. The data analysis technique used Covariance Analysis (ANACOVA). The learning device meets the requirements of validity, and good sensitivity reliability. The learning tools include Learning Implementation Plans (RPP), Student Worksheets (LKS), and Learning Outcomes Test (THB). Based on the results of Anacova with homogeneity test, from the calculations obtained F count = 1.0787 and F table¬ with a significance level of 5% = 1.98, so F count < F table causes to accept H0 and reject H1 which shows the variance of the two samples is homogeneous. This shows that problem-based learning assisted by teaching aids can improve student learning outcomes for geometry material.

Abstract

Mathematics learning in schools has not been linked to cultural concepts. Tea-eku dance is a cultural dance that contains a mathematical concept, the movement of the tea-eku dance contains a geometric concept. The purpose of this study is to apply tea-eku exercises through problem-based learning in increasing student interest and learning outcomes. The population in this study were all class VII students of SMP Adyaksa Ende for the 2022-2023 academic year. The sample in this study was class VII A as the experimental class and class VII B as the control class, each consisting of 13 students. The results of this study indicated that the learning interest of the control class students ranged from 55-78, while the experimental class with tea-eku dance media had scores ranging from 68 to 144 with an average score of 132.05 and a standard deviation. of 41,744. While student learning outcomes based on the results of the normality test using the Kolmogorov-Smirnov formula obtained normally distributed data (P = 0.000 <0.05). It can be interpreted that the application of tea-eku dance through problem-based learning can increase student interest and learning outcomes, seen from the statistical results F = 14.29 and F table = 4.28 with dk quantifier = 1 and dk denominator = 23, giving a value that significant.

Abstract

Formal education is one vehicle ‘for building quality human resources. The quality of human resources is very dependent on various aspects. One aspect that supports formal education is learning mathematics. This study aims to improve students' mathematical abilities and learning outcomes through a problem-based learning approach. This type of research is classroom action research with four stages, namely planning, implementation, observation, and reflection carried out in two cycles. Data was obtained from the instrument in the form of observations of mathematical thinking in the category of students' mathematical attitudes and tests to determine student learning outcomes. The subjects in this study were 20 class VII students of SMP Rewarangga Ende. The data analysis technique uses a comparative descriptive technique between cycles. The study results show an increase in students' mathematical thinking skills from the lowest initial level of 19% to 100% after the learning process in cycle II was carried out. At the same time, student learning outcomes have increased. This is known from the completeness of student learning outcomes, namely that from the initial test 20% increased in cycle II to 100%. Therefore, it can be concluded that Problem-Based learning can improve students' mathematical thinking and student learning outcomes in class VII students of SMP Rewarangga Ende.
