Abstract

Thingking geometry is the placement of students based on their ability to understand geometric figures. Van Hiele’s theory states that student’s geometric thingking levels are sequentially through levels or levels, namely level 1 (analysis), Level 2 (abstraction), Level 3 (deduction) and Level 4 (rigor). This study aims to determine and describe the achievement of van hiele geometric thingking level in term of learning independence and self-confidence. The reasearch method used in this research is descriptive qualitative. The instrument used is a van hiele geomery test item and a questionnaire. The provision of test and questionnaires was carried out to students of SMPN 4 Bengkulu City for the 2021/2022 academic year. The results showed that the achievement of van hiele’s geometric thingking level was influenced by independent learning and self-confidence.

Abstract

The socialization of the geogebra-assisted differentiated mathematics teaching module to Bengkulu Sports Talent High School teachers has been carried out successfully. The participants consisted of: 2 mathematics teachers, 1 physics teacher, 6 students, and 10 mathematics teachers who were FKIP UNIB Mathematics Education Masters students taking the Mathematics Learning Tools Development course. Activities are carried out in the following order: 1) Introducing Differentiated Teaching Modules, 2) Introducing 21st Century Learning, 3) Introducing the APOS Model, 4) Introducing Geogebra, 5) Implementing the Linear Program teaching module based on the APOS Model with the help of Geogebra. 6) Give Likert scale response questionnaires to participating teachers and students at SMANKO Bengkulu. After the response questionnaire was processed using a Likert scale, the results were: 1) the mean score of teacher responses to the Linear Program teaching module was 92.27 in the very good category, and 2) the student response score to the Linear Program teaching module was 87.6 in the very good category. The average response score of training participants to the Linear Program teaching module was 89.93 and was in the very high category. The faces of teachers and students look happy when implementing the Linear Program teaching module. The Physics teacher said he would use Geogebra as a Physics learning tool.

This research aims to determine 1) differences in creative thinking abilities between students who use geoboard teaching tools and students who use conventional ones in class VII, 2) differences in creative thinking abilities between students with high disposition ability and low disposition ability in class VII, 3 ) the interaction of geoboard teaching tools and mathematical disposition abilities on students' creative thinking abilities in class VII. This type of research is quasi-experimental research. Data collection techniques in this research are test and non-test techniques. The data analysis technique in this research uses a two-way ANOVA technique. The research results obtained from testing the hypothesis for each formulation are 1) there is a difference in creative thinking ability between students who use geoboard tools and students who use conventional in class VII with a significant value <0.001, 2) there is a difference in creative thinking ability between students high disposition ability with low disposition ability in class VII with a significant value of 0.020, 3) there is an interaction between geoboard teaching tools and mathematical disposition ability on the creative thinking ability of students in class VII with a significant value <0.001

Abstract

This research is development research which aims to produce valid and practical learning tools, namely RPP and Student Activity Sheets (LKPD) on arithmetic series material for class X SMA. This research began with an initial investigation analyzing the problems encountered at school. namely regarding the problems that occur in class X with mathematics learning, it is found that learning outcomes and students' active role in learning mathematics is still low. In this class the Merdeka curriculum has been implemented but differentiation learning has not been tried. The development model used is the plomp development model which consists of 5 stages, namely preliminary investigation, design, relations/construction (realization/construction), test, evaluation and revision (test, evaluation and revision) and implementation (implementation). Based on the results of data analysis, it was concluded that the mathematics learning tool using the PBL model was valid. RPP validation results 97%, LKPD 94% with very valid category. This means that the learning tools developed can be tested. Practical learning tools in small group trials with an average student response of 80% in the practical category

Abstract

Learning outcomes, especially mathematics, are still low both at the international and national levels. The results of the 2021 minimum competency assessment show that student achievement in Indonesia is still low. This requires educators to be more innovative in learning in class so that they can support students' thinking skills. This study aims to determine the effect of the Problem-Based Learning model on the mathematics learning outcomes of seventh-grade students of junior high school number 1 in North Bengkulu. This research is a quasi-experimental type with Nonequivalent Pretest-Posttest Control Group Design. The population in this study were all students of seventh-grade students of junior high school number 1 in North Bengkulu. The sample selection used a simple random sampling technique with class VII D as the experimental class and class VII E as the control class. Data collection was carried out using a test using the research instrument, namely the learning achievement test. Data were analyzed using the t-test statistic. The results showed that there was a significant effect of the problem-based learning model on the social arithmetic learning outcomes of seventh-grade students of Junior High School 1 in North Bengkulu.
