Critical thinking ability is the ability that must be possessed by all students in order to solve the problems encountered. Research that can reveal the critical thinking skills of students needs to be done. This study aims to describe the critical thinking skills of junior high school students in Jember in completing the jumping task problem in terms of learning styles in the material system of two variable linear equations. This type of research is qualitative descriptive research. The data collection method used is a questionnaire for learning style, critical thinking ability test questions based on jumping tasks, and interviews. The subject consists of three subjects from the single learning force category. Based on data analysis, students with a visual style can complete three jumping task questions and are able to fulfill five critical thinking ability indicators, namely focus, reason, inference, situation, and clarity. Students with an auditorial style can complete three jumping task questions and are able to fulfill five indicators of critical thinking skills: focus, reason, inference, situation, and clarity. Students with a kinesthetic style can solve only one question and fulfill five indicators: focus, reason, inference, situation, and overview. Suggestions Further research can see the critical thinking skills of students with double learning styles.

This research is a qualitative descriptive study which aims to describe the problem solving process of a professional teacher in finding solutions to problems of the Problem With Contradiction Information type. This research involved 1 mathematics teacher who had a professional teacher education certificate and had taught for at least 5 years (S1) and 1 mathematics teacher who had taught for at least 5 years but did not yet have a professional teacher education certificate (S2) and 1 prospective teacher who was still carrying out studies. S1 and does not yet have a professional teacher education certificate (S3). Data collection was carried out by tests and interviews. The research results showed that only S3 carried out all the IDEAL problem solving indicators and was the only research subject who realized the existence of contradictions in the given problem. Meanwhile, S1 and S2 do not look back and learn. All subjects started solving the problem by reading and making propositions from the problem given. S3 stated that he read twice, namely reading in depth and reading quickly to review the known data. S1 experienced Pythagorean priming when implementing the Making a Drawing and Backwards strategy. Meanwhile, S2 in implementing the Backwards strategy often has to do some work in his working memory so there are several steps that are not written down. S2 is aware that there is unnecessary data but considers it an open ended question. Meanwhile, S3 succeeded in stating that the question contained elements of contradiction and could not be done in the anticipating outcome and looking back steps. If you want to become a good problem solver then spend most of your time identifying and understanding problems and then determining how to work. Good problem solvers are not in a hurry but are still effective in solving problems. You even need to consider whether the problem can be solved or not.

The reality on the ground shows that students still make mistakes in solving problems in the form of Linear Program stories. This study aims to describe students' mistakes in solving word problems in linear programming material. The method used in this research is descriptive qualitative research. The subjects in this study were class X students of Karya Bahana Vocational School, Bekasi City. The instrument in this study was in the form of 5 questions in the form of descriptions. In addition to the instrument in the form of tests, interviews were used to dig deeper into students' answers to the questions presented. The results showed that the most errors made by students were in the aspect of errors in writing the final answers, and the fewest errors were in the aspects of transformation errors. The cause of reading errors is that students are unable to interpret sentences correctly and cannot find key words and important information. The cause of the error in understanding the problem was that students did not include the known data and the data asked. The causes of errors in the transformation are students not being able to model everyday sentences into mathematical symbols and errors in using mathematical operations. The cause of the process skill error was that the student was unable to write down the objective function and the student was unable to continue with the answer, while the cause of the error in writing the final solution was the inability of the student to draw conclusions correctly.

Mathematical understanding ability is a very important skill for students to achieve, because mastering mathematical involves more than just remembering formulas and knowing how to count, understanding concepts is also needed. But in reality, understanding skills are still low, students are still mostly fixated on existing formulas and examples given by the teacher. The purpose of this study was to see the improvement of mathematical understanding ability of VII students on Algebra material at Dharma Kartini Junior High School. This research uses classroom action research (CAR). The method used the spiral model of action research from Kemmis and McTaggart. The instrument used was a test instrument consisting of 10 questions of algebra material which was prepared based on the mathematical understanding ability of students whose learning used a scientific approach. This research was conducted in 2 cycles, each cycle consists of several stages starting from the planning, action, observation and reflection stages. The results of this study indicate that the aspects of students' mathematical understanding ability have increased as seen from the increasing percentage achievement on the question indicators after 2 learning cycles, namely in cycle I by 48% and cycle II by 78%. It is known that algebra material in class VII students of Dharma Kartini Junior High School can be influenced by the scientific approach with mathematical understanding ability. As more and more students showing understanding they can conclude and explain back what they have learned.

The importance of having the ability to understand mathematics includes this ability listed in the learning of mathematics in the 2006 KTSP mathematics curriculum and the 2013 curriculum. This study aims to examine the increased understanding of the material concept of derivatives of algebraic functions in class XI high school students. This type of research is classroom action research. This research was conducted on class XI high school students for the 2020/2021 academic year, consisting of 16 students. The instrument used is a test of students' mathematical understanding abilities, in the form of 6 questions that focus more on students' understanding abilities regarding the derivative of algebraic functions; observation sheet for teachers and students to see the condition of the implementation of the action. This study shows that students' mathematical understanding abilities have increased as seen from the questions tested on each test with an increase in mastery from initially 31.25% to 56.25%. The results of this study indicate that the application of a scientific approach can improve the comprehension skills of class XI students on material derived from algebraic functions.","PeriodicalId":294861,"journal":{"name":"(JIML) JOURNAL OF INNOVATIVE MATHEMATICS LEARNING","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126038020","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The aim of the research is to develop teaching materials assisted by media construct 2 software that are practical and appropriate for use in the learning process. The research method used is Research and Development (RD) using the ADDIE model. The research was conducted at SMPN 3 Rancabali with 12 class VIII students at Rancabali 3 Middle School for limited trials and 9 students at SMPN 2 Rancabali and 9 students at SMPN 1 Rancabali Public for a wider trial and 27 VIII C class students as an experimental class and 27 class VIII A students as the control class for product trials. The validators consist of ICT experts, subject matter experts and teachers. The data collection technique was in the form of a response questionnaire from students and teachers. The research results of the products developed were in accordance with the ADDIE research method with product feasibility categories based on ICT expert validation of 81.25%, material experts 85% and teachers 88% are all included in the very decent category. Products that have been validated are then tested on students through limited trials, wider trials and product trials and students are given practicality questionnaires with a final average result of 83.56% included in the very practical category. Based on the validation results of ICT experts, material experts and student and teacher responses, it was concluded that the teaching materials assisted by the media construct 2 software are valid and appropriate for use in learning. For further research, the researcher hopes to be able to develop teaching materials better according to the suggestions from the respondents.
