The Ability To Calculate Mathematical Multiplication Using Cross Line Method

Elementary school students generally consider mathematics learning difficult, especially in the matter of multiplication, so a method is needed to develop and improve mathematical calculation skills. One method that can be used is the cross line method. This research aims to improve the ability to calculate multiplication using the cross line method. This type of research is Classroom Action Research (CAR) with the subject of research on third grade students of SD Negeri 9 Tanrutedong, South Sulawesi. Techniques of data collection were test and observation. The instruments used were test sheets and observation sheets. The collected data were analyzed using descriptive statistics. The results showed that the use of the cross line method could improve students' ability to calculate multiplication. This is indicated by the increase in: (1) The average score of the ability to count in the first cycle of 67.39 increased in the second cycle to 92.00, (2) The achievement of student learning completeness from the first cycle of 65.22% increased in the second cycle to 100%, and (3) the increase in the average percentage of student activity in the learning process by 77.78% in the first cycle to 94.68% in the second cycle

Development of a students' worksheet based on problem-based learning (PBL) on the topic of anglesAbstractThis study aimed to produce a students’ worksheet or Lembar Kerja Peserta Didik (LKPD) based on Problem-Based Learning (PBL) on the topic of angles, which were feasible. This development research adopts the ADDIE development model with stages including Analysis, Design, Development, Implementation, and Evaluation. The quality of LKPD was viewed from the assessment of material experts, media experts, and students’ responses. The instrument used was a material expert questionnaire, a media expert questionnaire, and a students’ response questionnaire. LKPD was piloted on 32 seventh grade students of private junior high schools, namely SMP Muhammadiyah 1 Yogyakarta, Indonesia. The developed LKPD contained learning activities according to PBL steps, presented problems related to everyday life at the beginning of learning, and could be used in online learning. In terms of the material aspect, LKPD was considered good with an average score of assessment by material experts, namely 4.00. In terms of the media aspect, LKPD was considered good with a score of 3.6 by media experts. Students’ responses to the use of LKPD were included in the good category with an average score of assessment of 4.05. It could be concluded that the PBL-based LKPD for seventh-grade junior high school students on the topic of angles was feasible for use in the implementation of mathematics learning.

The purpose of this study was to develop a culture-based mathematics learning model through traditional Javanese games and find out the feasibility so that it could be used for elementary school students. This development research uses the ADDIE model (Analysis, Design, Development, Implementation, and Evaluation). Through these stages of development, it produce culture-based mathematics learning model through traditional Javanese games products with the main products in the form of model books, student books, teacher books, syllabus, lesson plans, and student worksheets. The research subjects were 19 fourth grade students at Klegenwonosari Elementary School. The data collection techniques in this study were carried out test and non-test. The data analysis technique in this study was in scores and percentages. Starting from the needs analysis of learning models, culture-based needs analysis, and curriculum analysis it is known that the use of mathematical learning models through traditional games has been done but outside learning, students were lack of knowledge about the traditional Javanese culture games that were Gobag Sodor and Engklek. Based on the results of the study, the mathematical learning model through traditional Javanese games fulfills the valid criteria with an average score of 3.79 from the model expert's assessment. Fulfill the effective criteria by obtaining the results of completeness of students 84.21% and get very positive students responses with a percentage of 90.90%. Therefore, Culture-based Mathmatics learning model through traditional Javanese games is suitable for elementary students. Keywords: traditional Javanes games, mathematics models, ethnomatematics
