Abstract

The purpose of this study was to describe the types of errors made by Class VIII students when solving SPLDV questions based on Newman's theory. This qualitative research aims to provide descriptive information about individuals or observed behavior in the form of written or spoken words. Written tests and interviews were used to collect data. The test was carried out on all 25 Class VIII students, and then 3 of the 25 students were selected as research subjects. Data were analyzed by reducing information, presenting information, and drawing conclusions. The results of the work of individual testers were analyzed for the types of errors using the Newman analysis method. The factors that led to student errors were then explained in the interviews. Based on the study results, it can be concluded that the errors made by students in the SPLDV questions are as follows: 1) Failure to understand the problem, including not recording what is known and what is not in the duration of the task. Ask when in trouble. 2) Conversion errors, including misunderstanding of the billing method used. 3) Commanding process failure involves failing to continue to complete the process. 4) Error in writing HP, including not writing down HP. Student errors occur when students are not careful when solving problems, are too busy, or do not practice narrative tasks. 3) Commanding process failure involves failing to continue to complete the process. 4) Error in writing HP, including not writing down HP. Student errors occur when students are not careful when solving problems, are too busy, or do not practice narrative tasks. 3) Commanding process failure involves failing to continue to complete the process. 4) Error in writing HP, including not writing down HP.

Abstract

This study aims to determine the effectiveness of applying M3 board media (Mean, Median, Mode) in Class VIII Statistics Materials at Lekok NU Middle School. This type of research is quantitative research. The research results show that: 1) The individual analysis results show the effect of using M3 board media on student learning outcomes in class VIII SMPNU Lekok. This is proven through the results of the independent sample t-test showing a significance value (2-tailed) 0.001 <0.05. Therefore, the hypothesis (Ho) is rejected, and the hypothesis (Ha) is accepted. 2) Student activities related to learning from the aspects observed are categorized as active. This is indicated by the acquisition of an average percentage of students' positive activity, namely 96.2% being active in learning mathematics according to predetermined standards, reaching 75% of students being actively involved in the learning process. 3) The average percentage of students positively responding to learning using the M3 board media is 81.13%. This is classified as a positive response as determined by the standard, reaching 75%. 4) The effectiveness of the media in research is seen in student learning outcomes, student activities, and student responses. The results of the descriptive and inferential analysis of the three effectiveness indicators have been fulfilled, so learning using the M3 board media effectively teaches mathematics to class VIII students of SMPNU Lekok.

Abstract

This study aims to analyze self-efficacy's effect on students' learning outcomes in class VII MTsn 01 Pasuruan. This research is a type of descriptive research with a qualitative approach. The main instruments in this study were researchers, and their supporting instruments were diagnostic tests, self-efficacy questionnaires, assignments, and interview guidelines. The subjects in the study were all students of class VII-A MTs Negeri 1 Pasuruan, with three students being selected: one having a high level of self-efficacy, one having a moderate level of self-efficacy, and one having a low level of self-efficacy. The results of this study indicate that the self-confidence variable and mathematics learning outcomes have a significant positive relationship. This means that the higher students' self-efficacy when doing assignments related to mathematics, the better the results of students' learning mathematics. Conversely, if the students' self-efficacy when doing tasks related to mathematics is lower, the students' mathematics learning outcomes will also be lower.

Abstract

This study aims to improve students’ creative thinking skills in problem-based, ill-structured, open-ended learning through stimulus. This study used learning strategies that simultaneously develop problem-solving strategies and knowledge discipline. This learning can be achieved if educational activities are focused on authentic, contextual, and relevant tasks or problems so that students can gather the necessary information, evaluate alternative solutions, and present solutions they believe in. Moreover, the ability to generate uncommon or extraordinary ideas must be raised from the problems that exist in learning. The ability to think creatively in mathematics in education using the Problem-Based Learning (PBL) approach assisted by GeoGebra is expected to be a practical approach to educating students in increasing their intellectual potential and familiarizing them to deal with non-routine problems and applying it in their daily life to become a student who can think creatively. This study used a quasi-experimental research method with a quantitative approach conducted at SMA Negeri 2 Cimalaka. The instruments used in this study were questionnaires and tests. This study's approach, which was integrated with GeoGebra, can be used as an alternative to learning mathematics in schools. It can be developed with other approaches according to problems in mathematics.

Abstract

This study describes the profile of students' mathematical reasoning ability in solving arithmetic rows and series problems. Based on the results of observations and interviews with the mathematics teacher of class X SMK Ma'wataibin Pagelaran Malang, information was obtained that 83% of students in the class tended not to be able to conclude the answer. This descriptive research uses a qualitative approach. The sample of this research is 19 students of class X SMK Ma'wataibin Pagelaran. They then selected one each in the high, medium, and low-level categories. Then, interviews were conducted with each subject to explore deeper information. The test instrument used is 1 question that contains four indicators of mathematical reasoning ability. The test results obtained that students in the high mathematical reasoning ability category amounted to 7 students, with a percentage of 36.85%. Students in the moderate mathematical reasoning ability category amounted to 8 students, with a rate of 42.10%. Students in the low mathematical reasoning ability category amounted to 4 students, with a rate of 21.05%. Based on the results of the data analysis, it is shown that high-category students fulfill four indicators of reasoning ability according to their abilities. Medium-category students correctly fulfill three indicators of mathematical reasoning ability: writing conjectures, doing work, and providing reasons/evidence. Low-category students only fulfill one indicator of mathematical reasoning ability, namely writing conjectures.

Abstract

Cryptography plays a crucial role in protecting the data from unauthorized access. Nowadays, various cryptographic algorithms are used. It is not meant for information technology to secure the proposed work's primary target to achieve these tasks and goals. Using a literature review, we study security information systems using S-Boxes. In the research, we discuss two different techniques to generate the new S-boxes and then discuss their other properties to improve the strength of encryption. This chapter is further divided into sections that comprehensively explain the various concepts.

Abstract

Mathematics and culture are things you can only do in your everyday life. There is a connection between mathematics and culture, com-monly called ethnomathematics. Many people need to understand that culture is a fundamental concept of mathematics to apply ethno-mathematics. The purpose of this research is to evaluate and also analyse in different ways the mathematical elements that occur naturally in the water tank building of the Raudhatul Ulum Islamic Boarding School, which is very important according to the mathe-matical aspects contained in the building. The results of this study indicate that the activities of the santri cannot be separated from washing clothes and even cleaning the body, as well as purification, which cannot be separated from the principles taught in Islamic scriptures (fiqh). This situation requires the construction of water tanks in Islamic boarding schools to be significant because the number of students in Islamic boarding schools is small but significant, and the water supply must be adequate according to Islamic religious law
