Abstract

Indonesian pupils need help solving problems, particularly in mathematics, due to the need for practice questions with the higher-order thinking (HOT) type. This research aims to develop a reliable and valid tool for assessing students' higher-order thinking skills in mathematics. Developing a test involves gathering requirements, creating questions, assessing answers, running trials, analyzing data, making adjustments, and finally putting everything together. The instrument trial was conducted at SMAN at Majalengka, West Java. The total number of test subjects was 32 students. Research data were collected using a description test. The test instrument consists of 10 descriptions, but only 6 had good validity based on the value of V on the V-Aiken. In addition, the test package produces reliable questions based on Cronbach's Alpha scores. The test results of the instrument showed that the HOTS of mathematics for Grade X students was good. This step provides an overview to teachers in designing valid and relevant instruments.

Abstract

Students' low mathematical creative thinking skills are the motivation for this study. The aim of this research is to develop context-based student worksheets (LKPD) that assess high school students' mathematical creative thinking abilities. This study uses the ADDIE development model with five stages (Analysis, Design, Development, Implementation, Evaluation), and the research is limited to the implementation stage. The subjects were Grade X students of SMAN 2 Majalengka. The instruments used included practicality questionnaires for teachers and students, validity questionnaires for media and material experts, and effectiveness tests through small-scale trials. A Likert scale was used to collect practicality and validity data, while N-gain analysis was applied to measure effectiveness. The results showed that LKPD with a contextual approach was valid, with an average material expert score of 3.17 and media expert score of 3.50. The practicality was also very good, with teacher practicality at 96.15% and student practicality at 87.26%. The average effectiveness was in the moderate category with an N-gain value of 0.38. Based on these results, it can be concluded that the developed LKPD is feasible, practical, and effective in improving students’ mathematical creative thinking skills. The contribution of this research lies in providing empirically tested, context-based LKPD that can be used as an innovative learning resource to foster mathematical creative thinking in high school students.

Abstract

Kemampuan berpikir kreatif matematis merupakan keterampilan penting bagi siswa dalam menghadapi berbagai situasi yang menantang pada abad ke-21. Penelitian ini bertujuan untuk menganalisis bagaimana siswa menerapkan empat tahap pemecahan masalah Polya dalam menyelesaikan soal peluang kontekstual secara kreatif. Sebanyak 32 siswa kelas XII di salah satu SMA negeri di Majalengka terlibat sebagai subjek penelitian dengan pendekatan kualitatif deskriptif, dengan berdasarkan hasil tes tertulis, tiga siswa dipilih secara purposif untuk mengikuti wawancara mendalam, yang masing-masing mewakili kategori kemampuan berpikir kreatif tinggi, sedang, dan rendah. Data dikumpulkan melalui tes uraian kontekstual, observasi, dan wawancara semi-terstruktur. Hasil penelitian menunjukkan bahwa sebagian besar siswa mampu melaksanakan rencana penyelesaian secara sistematis, namun masih mengalami kesulitan pada tahap memahami masalah dan memeriksa kembali hasil. Hanya 16% siswa yang melakukan refleksi akhir secara efektif. Temuan ini menunjukkan bahwa sebagian besar siswa mampu melaksanakan strategi penyelesaian, yang mencerminkan kelancaran dan elaborasi dalam berpikir kreatif matematis. Namun, keterbatasan siswa dalam memahami konteks permasalahan membatasi keluwesan dan keaslian mereka dalam menghasilkan berbagai pendekatan penyelesaian masalah. The ability to think creatively in mathematics is crucial for pupils to deal with a variety of difficult problems in the twenty-first century. The purpose of this study is to examine how students creatively solve contextual probability questions using Polya's four stages of problem-solving. Using a descriptive qualitative approach, 32 twelfth-grade students from a Majalengka public high school served as research subjects based on the written exam results, three students were purposefully chosen to participate in in-depth interviews, each of whom represented the categories of high, medium, and poor creative thinking abilities. Semi-structured interviews, observations, and contextual essay examinations were used to gather data. The study's findings indicate that while most students can follow the solution plan methodically, they still struggle with comprehending the issue and analyzing the findings. Just 16% of students completed their final reflection successfully. based on the written exam results, three students were purposefully chosen to participate in in-depth interviews, each of whom represented the categories of high, medium, and poor creative thinking abilities.

Abstract

Test content-based proof of validity is a type of evidence that supports the validity of a measuring instrument. This research aims to develop a mathematical problem-solving assessment instrument utilizing five experts. This study is classified as developmental research and follows a research design that includes two separate stages: the preliminary design stage and the prototype stage. However, its application is restricted to Prototype 1 and Prototype 2, specifically for expert evaluation. This instrument was designed explicitly for grade VIII students studying mathematics, covering all the topics from the odd semesters. The analysis progressed through three distinct stages "” curriculum analysis, content analysis, and context analysis "” each contributing to a comprehensive understanding of instructional resources. The study sought to narrow the gap between theoretical knowledge and practical application in mathematics education by incorporating real-world context. Surveys have revealed difficulties in answering mathematical problems, highlighting the need to address gaps in learning to improve competency. The careful and thorough construction of test instruments, considering factors such as validity, established the foundation for creating accurate assessment tools. The content validity assessment by the expert panel, with scores ranging from 0.817 to 0.884 based on the V-Aiken category, confirms that the instrument is vital in assessing students' mathematical problem -solving skills, and the implementation of this study yielded many valuable insights for educators and academics. This study helps improve mathematics education resources and evaluations to promote mathematical thinking.

Abstract

Assessing higher-order thinking skills (HOTS) in mathematics education remains challenging because available instruments often measure critical thinking (CT), creative thinking (CrT), and problem-solving (PS) separately, limiting a coherent evaluation of their interrelated nature. This study developed and empirically validated an integrated set of quality indicators for HOTS assessment using a mixed-methods design. In the qualitative phase, focus group discussions (FGDs) with five experts in mathematics education and educational evaluation generated theory-driven indicators grounded in instructional practice. In the quantitative phase, 70 participants (university lecturers, secondary school teachers, and undergraduate students) were selected through stratified purposive sampling to evaluate the indicators. An exploratory factor analysis (EFA) was performed using principal axis factoring with varimax rotation, and factorability was confirmed using Kaiser-Meyer-Olkin (KMO) and Bartlett’s test of sphericity. The results showed satisfactory construct validity (KMO=0.75; Bartlett’s p
