Abstract

Critical thinking is needed in problem solving. To solve problems, students will use a variety of strategies. Critical thinking ability play a role in determining the strategy used, which is also influenced by students' cognitive styles. In this research, the cognitive style discussed is reflective cognitive style. This research is a qualitative with a case study approach. This research aims to describe the critical thinking ability of students in solving algebraic numeracy problems based on reflective cognitive style. This research was conducted in Class VIII Junior High School students. The research subjects were selected through MFFT (Matching Familiar Figure Test) and Mathematical Ability Test. Data analysis techniques include data reduction, data display, and conclusions. The selected research subjects from reflective took the critical thinking ability test and interviews. The results of the critical thinking test and interviews were analyzed to describe the critical thinking in solving algebraic numeracy problems. The results showed that reflective cognitive style student fulfill each criteria of critical thinking ability FRISCO (Focus, Reason, Inference, Situation, Clarity and Overview). The reflective student is able to carry out the focus and reason criteria of critical thinking ability by identifying the main points of the problem and providing reasons for the relationship between what is known and asked correctly and completely. Reflective student is able to carry out the inference and situation criteria by deciding on the right strategy and solving the problems given correctly and systematically. Reflective student can also able to carry out the clarity and overview criteria of critical thinking ability by drawing conclusions and re-examining the solution of the problems given. So, reflective cognitive style student is categorized as very critical. It is suggested that teachers provide more practice questions and provide further discussion with limited working time.

Abstract

Mathematics learning videos are audio visual media that make lessons more engaging by aligning with students’ audio-visual learning styles and illustrating real-life applications through digital storytelling. However, numeracy performance remains low—only 19% (4 of 21 students) mastered topics like mean, median, mode, and range. Efforts to address this problem are to use mathematics learning videos based on digital storytelling to strengthen students’ numeracy. This study aims to describe the content validity making such a video for strengthening students’ numeracy skills. In this research used the ADDIE development model, which focuses on three stages: Analyze, Design, and Develop with evaluations at each stage. However, this article focuses on the validation assessment of mathematics learning videos based on digital storytelling. The instruments used consist of a material expert validation instrument and a learning video validation instrument. The media was validated by three experts in the field of learning media, visual programming, and digital storytelling. The data analysis technique uses the Aiken V formula. Based on this, the results of the validation analysis are shown by obtaining a score of 0.854 from video experts (highest in usefulness) and 0.83 from material experts (highest in learning objectives) both were categorized as valid. The assessment by experts shows that the mathematics learning video is suitable for use with revisions. Several revisions were made to mathematics learning video based on digital storytelling to make it more interesting. Further research is recommended to develop the mathematics learning video into an application that can be used offline and allows for automatic answer storage settings.

Abstract

The low percentage of numeracy proficiency among junior high school students, as reported in the 2024 Indonesian Education Report, emphasizes the importance of high-quality numeracy questions equivalent to the Minimum Competency Assessment as effective practice materials to enhance students' numeracy skills. This study aims to analyze the characteristics of numeracy questions equivalent to the Minimum Competency Assessment delivered through the Jotform platform for junior high school students. The items are developed as online practice materials aimed at familiarizing students with solving numeracy problems in accordance with the standards of the national competency assessment. This research is an exploratory study using a quantitative approach. The primary data were collected from the result of 20 numeracy items distributed through Jotform to 27 students enrolled in the eighth grade of a privacy secondary school located in Surabaya. Four analyses were conducted to examine the item characteristics: validity, reliability, difficulty index, and discrimination index. Findings indicate that the average validity of the items falls within the moderate level, the reliability in categorized as high, the average difficulty index is also in the moderate range-suggesting the items are effective for evaluating students’ numeracy skill-and the average discrimination index demonstrates an excellent classification. In light of the results, the questions are considered appropriate for use in online numeracy practice.

Abstract

Statistical literacy is the process of understanding statistical data or information, processing statistical data or information, interpreting the results of data processing, and evaluating answers. Statistical literacy is important in processing information to make decisions and conclusions. This research adopts a qualitative approach with a case study design aimed at describing the statistical literacy of junior high school students with high statistical ability in solving numeracy problems. The research subject is a student with high statistical ability based on a statistical ability test. The indicators of statistical literacy in this study are understanding statistical data or information, processing statistical data or information, interpreting the results of data processing, and evaluating answers. The results show that students with high statistical ability solve numeracy problems by understanding statistical data or information well, processing statistical data or information accurately and systematically, interpreting the results of data processing, and always evaluating answers by recalculating. Teachers are advised to encourage students to evaluate their answers by checking them again, not only by counting them again but also by checking the entire answer in order to obtain the correct answer.

Abstract

Creativity is the ability to generate new ideas that are needed in the world of work, which demands innovation and solutions to complex problems. In the context of education, students still find it difficult to develop their creativity because learning is still carried out in a conventional manner. This research is a qualitative study that aims to describe the creativity of high school students in designing miniature suspension bridges using a STEM approach to quadratic functions, as viewed from a field-dependent cognitive style. The data for this study was collected from twenty-eight high school students at a school in Malang City. The research data was collected through the group embedded figures test, mathematics ability test, miniature suspension bridge products, and interviews. The research subjects were two students with a field-dependent cognitive style. The results of the study indicate that cognitive style influences how students model quadratic functions in a miniature suspension bridge project, and that students with a field-dependent cognitive style do not utilize quadratic functions when constructing the suspension arches. Therefore, further research is recommended to strengthen the integration of mathematical concepts in STEM projects.

Abstract

Analogical reasoning is a person's thought process to draw conclusions by processing information and identifying factual relationships so that it can be used to solve problems. Analogical reasoning is important in solving mathematical problems. However, some studies show that analogical reasoning in low mathematics ability students still requires in-depth research, especially in solving problems. This study aims to describe the analogical reasoning of low mathematics ability students in solving open-ended problems on algebra topics. This study used a qualitative method with a case study approach, in which data were obtained through tests and interviews with one eighth-grade student with low mathematical ability. The subject was selected based on mathematical ability, communication skills, and problem-solving skills. Analogical reasoning was analyzed based on four stages according to Ruppert: structuring, mapping, applying, and verifying. The results of the analysis show that students with low mathematical ability only identify some of the information in the structuring stage, do not find similarities in structure in the mapping stage, use the wrong solution strategy in the applying stage, and do not check the solution in the verifying stage. This research is expected to lead to further studies that can explore analogical reasoning on various topics, classes, reviews, mathematics ability levels, and other open-ended problem categories to gain a deeper understanding of students' analogical reasoning.

Abstract

The limited use of GeoGebra Classroom as a process-based assessment tool for measuring trigonometry problem-solving skills at the senior high school level highlights the need for an alternative technology-based assessment. This study aims to describe the development process and produce a trigonometry problem-solving skills assessment design for high school students integrated with GeoGebra Classroom and fulfilling the criteria of validity, practicality, and effectiveness. This study uses a research and development method with reference to the nine steps of instrument development according to Retnawati, which include formulating instrument objectives, determining theory and material coverage, compiling indicators, developing test items, expert validation, revision, trial, data analysis, and assembling the final instrument. The results show that the assessment design development process was carried out according to the stages of Retnawati's model and produced six descriptive test items on the trigonometric comparison material of right triangles integrated with GeoGebra Classroom, with very high content validity (Aiken's V = 0.90 – 0.97), practicality in the practical to very practical category, and effectiveness indicated by the proportional level of item difficulty and sufficient to very good discrimination power. Based on these results, it is concluded that the developed trigonometry problem-solving skills assessment design fulfills the criteria of validity, practicality, and effectiveness. Thus, this assessment design has implications as an alternative technology-based assessment that is suitable for use in high school trigonometry learning to support visualization, exploration, and measurement of students' problem-solving skills.
