Abstract

The low of students' reasoning ability is caused by the teacher's lack of ideas in applying the learning model in the class. This study aims to conduct a literature review on the improvement in students' of senior high school on mathematical reasoning ability after got the connecting, organizing, reflecting and extending (CORE) model and to determine the advantages of the CORE model in mathematics learning in the class. The research used is a qualitative using the systematic literature review (SLR) method with a survey-based descriptive approach. The survey was conducted on secondary data, namely the results of basic research on the CORE model on students' mathematical reasoning abilities. The research technique used data collection, data analysis, and drawing conclusions. The results indicate that the student's responses to the CORE learning model were positive. Based on the research criteria from 8 articles, students’ can improve the mathematical reasoning after got the connecting, organizing, reflecting and extending (CORE) model, compared to students received conventional mathematics learning and the advantages of the CORE model in the class, namely developing students' activeness in learning, training memory, developing students' reasoning power, developing reasoning mathematical skills with the stages of connecting, organizing, reflecting and extending.

Abstract

This study aims to describe students' mathematical literacy skills in solving statistical literacy questions based on Honey-Mumford learning styles. The statistical literacy questions used in this study are questions of the AKM type which are related to statistical material about the size of data concentration. The subjects of this study were first semester students of the Department of Mathematics, State University of Malang. The instruments used in data collection were test questions, interview guidelines, and instrument validation sheets. The results of the study show that there are differences in the level of students' abilities in several aspects that become competencies in mathematical literacy. Students with a reflective learning style tend to be more detailed in terms of using symbols and mathematical formulas, students with a theoretical learning style tend to be more thorough in understanding and translating the meaning of the questions, while students with a pragmatic learning style tend to prefer using simple reasoning with minimal use of mathematical symbols/formulas.

Abstract

Math word problems are very important for students to understand, because math word problems are related to life. However, there are still many students who have difficulty in solving math word problems. Different levels of learning motivation can affect students' mistakes in solving math word problems. This study used descriptive qualitative method. The subjects of this study were 18 students of class XI IPS 3 MAN 5 Tasikmalaya and 3 subjects were selected by purposive selection taking into account the results of the questionnaire scores from each category and the number of errors. The results of this study, subjects with high motivation categories only made 2 mistakes only in the type of comprehension error, namely not writing down what was known and not writing down what was asked in the problem. Subjects in the category of moderate motivation made 5 errors in the types of comprehension errors (Comprehension Error), Skill Error (Process Skill Error), and final writing error (Encoding Error), namely not writing down what is known, not writing down what is being asked, not writing examples. , wrong in calculating, and wrong in writing the final conclusion. Whereas subjects with low motivation categories made 7 mistakes in all types of errors, namely not writing down what was known, not writing down what was being asked, not writing examples, wrongly compiling the equation of the problem, not continuing the solving process, wrong in doing the calculations, and not write a final conclusion. It is recommended for further researchers to conduct interviews with research subjects to obtain more in-depth information.

Abstract

This research is a continuation of the article Development of Trigonometric Material Teaching Materials through the RME Approach (Meika et al., 2023). Before the teaching materials that have been developed are used, it is necessary to know in advance the effectiveness of the teaching materials. Therefore, it is necessary to trial the use of these teaching materials in a class to determine their effectiveness. The purpose of this study is to determine the effectiveness of RME-based LKPD on the ability to understand concepts in terms of learning completeness. The method used is Design Based Research (DBR) with the Plomp development model consisting of three stages, namely: Preliminary Research, Prototyping Stage and Assessment. This article contains the results of the assessment phase. At the assessment stage, a final test was carried out and filled out a student response questionnaire to determine the effectiveness of the LKPD that had been developed. The effectiveness of LKPD is seen from the completeness of student learning outcomes. The final test results showed that the average score of class X Science 1 was 78 with three students who did not complete KKM. KKM Madrasah Aliyah Mathla'ul Anwar Menes Centre is 71. The percentage of students who achieved completion was 85.72%. Therefore, LKPD products have been effective in developing students' ability to understand mathematical concepts. The results of the student response questionnaire showed that the average percentage of all aspects assessed was 77.87% with the category "Good".

Abstract

The background of this development is the importance of higher order thinking skills for primary school students, to support these abilities, it is necessary to have learning resources that support and are in accordance with technological developments. However, the facts in the school show that existing learning resources are still conventional and have yet to lead to the achievement of higher order thinking. Based on this background, the purpose of this development is to develop HOTS-based digital student worksheets in mathematics learning in primary schools. This research was conducted at SDIT Al-Hujjaj Cilegon City for fifth grade students. The development model used is the ADDIE model, namely Analysis, Design, Development, Implementation, Evaluation. The instruments used to measure the feasibility of this products are expert validation questionnaires consisting of media experts, content experts, and language experts, practicality questionnaires and higher order thinking skills tests. Based on the results of processing the expert validation questionnaire, the results obtained are the media expert's assessment getting an average percentage score of 88% with very feasible criteria, the content expert's assessment getting an average percentage score of 91% with very feasible criteria, and the linguist's assessment getting an average percentage score of 90% with very feasible criteria. The results of processing the practicality questionnaire distributed to teachers and students received a percentage score of 95.2% with very practical criteria. While the test results show the achievement score of students' higher-level thinking skills of 93.8% with very good criteria and above the minimum completeness criteria set at 70. Based on the results of the analysis, it can be concluded that the student worksheets developed are feasible and practical to use as complementary teaching materials and effective in developing students' critical thinking skills in mathematics learning in primary schools.

Abstract

The purpose of this study was to measure students' creative thinking skills using stacking blocks as media. The research method used is a quantitative method. The research sample consisted of 60 students from class VII-2 and VII-3. The instrument used is a test of the ability to think creatively and use stacking blocks as media. Based on the results and discussion conducted, the average value in the experimental class is higher than the average value in the control class. By using stacking blocks as media, students can improve their creative thinking skills. Out of a total of 60 students tested, only 58.33% of students had a low level of creative thinking. Of the four indicators of the ability to think creatively there are various categories such as poor, sufficient, good, and very good. In the learning process, the teacher can evaluate the level of students' creative thinking by using various types of media, including constructing blocks, and the teacher can channel their creativity in the learning process.
