Abstract

Research on the development of Student Worksheets (LKPD) integrated with Islamic values is motivated by the absence of LKPD that integrates Islamic values in the mathematics learning process and the low interest in learning MTs Asy-Syafi'iyah Kendari students. This study aims to develop valid, practical, and effective LKPD. The research method used is research and development with the ADDIE model. The results showed that the LKPD integrated with Islamic values was very valid to be used in the learning process based on the results of the validity by material experts of 3.73 (very valid) and the results of the validity of religious experts at 3.07 (valid). LKPD is also very practical to use in the learning process at MTs Asy-syafi'iyah Kendari based on assessing teacher responses and student responses. The effectiveness of LKPD can be seen from the students' mathematics learning outcomes, where the results show that there are differences in the mathematics learning outcomes of class VII MTs Asy-Syafi'iyah Kendari before and after LKPD is used in the learning process, based on the results of the Wilcoxon test with a significance value of 0.018.

Abstract

Mathematical self-efficacy and the snowball-throwing learning model play a role in student learning success. Mathematical self-efficacy is a student's perception of mathematical abilities. The study aimed to analyze students' critical thinking skills based on mathematical self-efficacy through the application of the snowball-throwing learning model to material composition functions. The research method uses a qualitative with the type of case study research. The number of respondents consisted of three students representing high, medium, and low mathematical self-efficacy categories. The research instrument used tests of critical thinking skills, questionnaires, and interviews. The data analysis technique uses three stages, namely data reduction, data presentation, and conclusion the data. The results of the study were obtained as follows: 1) Students who have high mathematical self-efficacy have high critical thinking skills with all indicators of critical thinking skills fulfilled, 2) Students who have moderate mathematical self-efficacy have critical thinking skills with only one indicator fulfilled, and 3) Students who have low mathematical self-efficacy do not have all indicators of critical thinking skills. Learning the composition function using the snowball-throwing learning model is appropriate when used for students who have a high level of mathematical self-efficacy to train students' critical thinking skills.

Abstract

This study aims to develop and validate a multidimensional instrument that will measure the interest in mathematics among Indonesian adolescents (aged 12-21 years). The developed instrument must meet psychometric standards in terms of content, construct, and concurrent validity. This instrument is called the “Skala Minat Matematika Remaja” (SMMR). The existence of SMMR is important because: (1) it is based on a validated structure and content of interest in the literature, (2) it accommodates the measurement of interest during adolescence, and (3) it specifically measures mathematics interest, which will be useful in the mathematics learning process. Three sample groups were taken from secondary school to university level to complete the SMMR instrument. A quantitative approach was used to test three types of validity. Construct validity was tested using exploratory and confirmatory factor analyses. Exploratory factor analysis (EFA) resulted in a 20-item SMMR with four dimensions (engagement, knowledge, emotions, and value) that explained 58% of the total variance. This indicates that the selected items can effectively explain the four dimensions of interest. Furthermore, confirmatory factor analysis (CFA) on the third sample group confirmed that SMMR is suitable for application among different groups of adolescents. SMMR scores showed a significant negative relationship between interest and age. This relationship indicates that SMMR has good concurrent validity.

Abstract

Problem-solving ability is a primary skill students should acquire in learning mathematics and is often connected to Adversity Quotient (AQ). This qualitative descriptive study describes the ability to solve PLSV problems regarding AQ (climbers, campers, and quitters) in 7th-grade students of SMP Negeri 21 Surabaya. Data were collected through questionnaires, tests, and interviews using instruments such as the AQ questionnaire sheet, Word Problem Solving Test (TPWP), questionnaires, and interview guidelines. The problem-solving ability in this study refers to the four stages of Polya's problem-solving ability including understanding the problem, planning, implementing, and evaluating. The results of this study showed that (1) the climbers subject was able to accomplish all of Polya's stages, (2) the campers subject, was able to accomplish three stages of Polya's problem solving, which were able to understand the problem, plan the problem solving, and carry out the problem-solving. Whereas, (3) the quitters subject, was unable to complete Polya's problem-solving stages as it showed that the subject was poorly understanding the problem, planning to solve the problem, implementing the solution plan, and incapable of looking back at problems that had been solved.

Abstract

Problem-solving is one of the process standards that has been discussed by NCTM and is very important for prospective mathematics teachers to master. The reality is that prospective mathematics teachers have low problem-solving abilities, so it is necessary to analyze the causes of these low-solving abilities. This research aims to uncover the causes of the low problem-solving abilities of prospective mathematics teachers using PKL, USG, and fishbone diagrams. The research method used is qualitative. The research subjects were students of the Mathematics Education study program, FMIPA, Universitas PGRI Banyuwangi who were prospective mathematics teachers according to the achievements of study program graduates. The main instrument of this research is the researcher. Meanwhile, supporting instruments include tests, open questionnaires, researcher notes, interviews, and documentation. Data analysis was carried out using the APKL, followed by the USG method, and then using the fishbone diagram. The results of the research reveal that the causes of low problem-solving abilities are inadequate procedural abilities in solving mathematical problems, inadequate declarative knowledge or knowledge of mathematical concepts, inadequate representational abilities, biological problems, and inadequate interests. This research provides signs for educators to anticipate the causes of the low problem-solving abilities of prospective mathematics teachers.

Abstract

Algebraic thinking is important for developing students' mathematical generalization abilities, and identifying patterns, shapes, and symbols. This study uses a qualitative descriptive approach that aims to describe the profile of students' algebraic thinking in solving modeling problems. The subjects of this study were 158 fifth-grade students in two private schools in Surakarta, Central Java. The data collection instrument used was six test questions related to the modeling component adopted from Ralston. Prior to use, the instrument was validated by 3 elementary school mathematics learning experts and tested on 10 students who were not the subject of the study. Based on the test results, there were 12 students who scored in the high category. This study focuses on analyzing the algebraic thinking profile of students with high categories. The results showed that high-category subjects were able to demonstrate understanding related to modeling indicators in algebraic thinking, namely understanding the meaning of the equal sign (=) as an equivalence relationship, using variables to solve problems in the form of equations, and understanding the relationships between arithmetic operations. However, a small number of subjects still experience calculation errors and understanding errors in algebraic operations. Hence, it can be concluded that subjects with high categories are able to demonstrate algebraic thinking skills in the modeling component

Abstract

Technology that continues to develop requires teachers to continue to innovate in presenting quality learning media. Mobile learning is a medium that can be used in learning because of the ease in the process of using it anywhere and anytime. On the other hand, critical thinking is a very important ability in mathematics. Through critical thinking skills, students are required to be able to generate thoughts and choose the right steps to solve a problem. However, the results of the field study show that students' critical thinking skills in material on compositional and inverse functions are still very low. This study aims to develop mobile learning named KORS to train students' critical thinking skills in the matter of compositional and inverse functions. This type of research is development research with the ADDIE model. The subjects of this study were practitioners and six high school students. In collecting data, assessment instruments were used by media experts and material experts, as well as student and teacher response questionnaires. The results of this study obtained KORS mobile learning media that were feasible to use with a percentage of 79% from media experts and 78.67% from material experts. The practicality of the media from the teacher's assessment obtained a percentage of 83.33% and based on the results of small-scale trials obtained a student response questionnaire percentage of 82.67%.

Abstract

Students' low reading interest greatly affects learning outcomes in Vector Analysis class. This is due to the rare interaction between students and learning resources in class. To increase student activity in reading and understanding the concept of vector analysis material, an e-LKM product is needed. This study aims to develop Student Worksheets (LKM) in electronic form that is integrated with numeracy literacy which can be used for learning vector analysis courses by knowing the validity and practicality of procedures so that the use of these e-LKM can improve students' critical thinking. This development research uses the ADDIE model (Analysis, Design, Development, Implementation, and Evaluation). Furthermore, the evaluation stage is carried out at each stage to improve the e-LKM that is made. The subjects were 21 students in semester VI of class C Mathematics Education FKIP Universitas Ahmad Dahlan. The research data was obtained by collecting questionnaires from material experts, media, and students' responses to the practicality of the media being developed. From the results of the questionnaires distributed, the average questionnaire from the two material experts and media experts showed excellent criteria with a mean score of 4.611 and 4.47 respectively. The results of student responses to product use show excellent criteria with a mean score of 4.27. Based on these results, the e-LKM that is used is proven to be valid and practical.
