Abstract

The lack of development of Student Worksheets  that match what is needed by students can be one of the reasons why many students have difficulty understanding learning materials. This study aims to describe the process and results of the development of the mathematics worksheets based on Problem Based Learning by utilizing liveworksheets on geometric sequences and series material. The type of this research is research and development. This worksheet is designed using Canva and Microsoft Word by utilizing liveworksheets. The subjects of the field trial were 28 students of class XI. This research uses the Four D model from Thiagarajan which consists of the stages of definition, design, development, and dissemination. Data collection methods consist of observation, test, and questionnaire methods. Based on the results obtained from trials in the field, it can be concluded that the mathematics worksheets based on Problem Based Learning by utilizing liveworksheets on geometric sequences and series material met the valid, practical, and effective categories. Other researchers can make maximum use of the features provided on the liveworksheets site because in this study they only utilized a few features and must be alert in anticipating when an error occurs on the site while it is being used.

Abstract

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.

Abstract

Soybean is one of the main food commodities after rice and corn. Tempe is a traditional food made from soybeans. Tempe is widely produced by small and medium industries. This study aims to determine the maximum benefits obtained in the District of Banjar, Banjar City, West Java Province in producing tempe. This type of research is a descriptive study with a qualitative approach. By using the probably sampling method, take a random sample. Determination of the sample is taken in 3 tempe productions with different tempe production income. By determining the decision variables, objective functions, and constraint functions by linear programming methods. In Tempe production in the Banjar District, Banjar City, West Java, the maximum profit was Rp. 29.257.080 and the maximum income was Rp. 28.862.790. The maximum profit and income are obtained from a large workforce so that it can produce a lot of tempe production and the cost of depreciation of the tool is small. The more tempe production, the more revenue obtained.

Abstract

This study aims to describe students' spatial-visual ability in solving PISA questions in shape and space content based on David Keirsey's personality type are guardian, artisan, idealist, and rational. This type of research used in this research is descriptive qualitative research. Subjects in the study were eight students from Class XI MIPA 1 SMA Negeri 7 Kediri consisting of two students from each of the guardian, artisan, idealist, and rational personality type. The data collection methods used were questionnaires, tests, and interviews. The instruments used in this study were MBTI questionnaires, shape and space content PISA test questions, and interview guidelines. The results showed that the achievement of the characteristics of the eight spatial-visual abilities of the subjects differed. Students with guardian personality are able to fulfill two characteristics of visual-spatial intelligence consisting of pattern search and conceptualization, but unable to fulfill the characteristics of problem-solving and imagining. Students with artisal personality are able to fulfill two characteristics of visual-spatial intelligence which consist of pattern searching and imagining. Students with idealist personality are able to fulfill the three characteristics of visual spatial intelligence which consist of pattern searching, conceptualizing, and imagining. Students with rational personality are able to fulfill all the characteristics of visual abilities consisting of pattern search, conceptualization, problem solving, and complete imagination in solving shape and space content PISA questions. This can be seen from the results of solving the questions given and interviews conducted on the research subjects.

Abstract

Critical thinking skill is necessary to be learned by every students, because by thinking critically students are able to understand other mathematical skills. One of the problems that can improve critical thinking skills is Problem With Contradiction Information (PWCI), which means problem that contains wrong information. Every student has their own characteristics, it also influences their critical thinking. One of the ways to identify a type of personality people is by using the Myers Briggs Type Indicator (MBTI), which classifies humans based on several perspectives, such as how to understanding and receiving information (Sennsing-Intuition), also how to make a conclusion and decision (Thinking-Feeling). The purpose of this study is to describe the critical thinking skills of students with sensing, intuition, thinking and feeling personalities. This research is a descriptive study with a qualitative approach. This research was based on SMAN Arjasa, and the subject was 8 students consisting of 2 students each with sensing, intuition, thinking and feeling personality. Data collection methods used are test and interview. The analysis technique used is the analysis of test results, interviews and triangulation.  The results of this research revealed that students with sensing, intuition, thinking and feeling personality types have their own characteristics when solving the problem. The results of the critical thinking test found that there were no students who were able to fulfill critical thinking skills but there were students who were able to find contradictory information in the question

Abstract

Errors in constructing concepts often occur in mathematics learning, especially in the topic of integer operations. These errors arise because students tend to memorize procedures or rules without fully understanding the underlying concepts. This research aims to analyze students' errors in constructing the concept of integer operations based on assimilation and accommodation. This study uses a qualitative method with 16 students from class VII B at MTs Baitul Hikmah Tempurejo as subjects. The data collection methods in this study included tests and interviews. Data analysis was carried out through the stages of analyzing test results, conducting interviews, and triangulating the data to ensure validity. Based on the analysis and discussion of the data, it can be concluded that all subjects experienced errors in constructing the concept. Four types of concept construction errors were identified: Pseudo Construction, Construction Hole, Mis-logical Construction, and Mis-analogical Construction. Pseudo Construction occurs when a student merely memorizes phrases like "negative meets negative, the result is positive" without a deeper understanding of the concept. Construction Hole occurs when a student provides incorrect answers due to incomplete understanding or failure to comprehend the problem. Mis-logical Construction happens when a student makes an incorrect assumption or conclusion, while Mis-analogical Construction involves false analogies, such as equating the concept of adding negative numbers with adding positive numbers. The results of this study are expected to provide insights into the types and causes of errors in concept construction made by students, which can then be used as a basis for developing effective learning strategies to help students understand concepts correctly.
