Abstract

This study aims to describe the students’ mathematical connections in terms of the locus of control. The mathematical connection indicators in this study are writing down the mathematical concepts that underlie the answers, recognize the relationship of various mathematical ideas and mathematical topics that can be related to problems of everyday life, and understand how to solve mathematical ideas that are interrelated and underlie each other to obtain an integrated whole. Data collection methods in this study were questionnaires, tests, and interviews. The subjects of this study were six seventh-grade students at MTs Negeri 7 Jember. The data analyzed by qualitative descriptive analysis. Based on the tests and interviews analysis, we known that students with internal locus of control could write mathematical concepts as a two variable linear equation system (TVLES). Students can connect TVLES material with problems, for example, represented the object in variables x and y. Students can also solved the problems related to TVLES material by using common examples, elimination and substitution methods. While the students’ with external locus of control also can write the mathematical concepts as a TVLES. But the students did not write in detail the relationship between TVLES material and the problem. Students can not solve problems by using TVLES solutions such as elimination and substitution, but students only use estimates in finding solutions.

Abstract

Proses berpikir kreatif siswa dapat diketahui dengan cara memberikan siswa masalah open-ended. Penyelesaian soal open-ended memerlukan kemampuan pemecahan masalah yang berpengaruh terhadap upaya seseorang untuk dapat menyelesaikan masalah yang dihadapi. Kemampuan seseorang untuk menghadapi tantangan atau kesulitan biasa disebut dengan Adversity Quotient (AQ). Tujuan dari penelitian ini adalah untuk mendeskripsikan proses berpikir kreatif siswa climber, camper, dan quitter dalam pemecahan masalah open-ended. Jenis penelitian ini adalah deskriptif kualitatif. Pengumpulan data dilakukan dengan memberi angket ARP, tes open-ended, dan wawancara. Berdasarkan hasil analisis data disimpulkan bahwa siswa climber melakukan keempat tahapan proses berpikir kreatif yaitu tahap persiapan, tahap inkubasi, tahap eliminasi, dan tahap verifikasi. Siswa camper hanya melakukan tiga tahapan proses berpikir kreatif yaitu tahap persiapan, tahap inkubasi, dan tahap eliminasi. Siswa quitter hanya melakukan dua tahapan proses berpikir kreatif yaitu tahap persiapan dan tahap inkubasi, sedangkan tahap eliminasi tidak dapat terpenuhi karena hanya dilakukan pada salah satu dari yang ditanyakan pada soal.

Abstract

This study aims to develop Realistic Mathematics Education (RME) learning tools integrated with agricultural activities, fulfilling the criteria of valid, practical, and effective to improve numeracy skills, particularly in the topics of direct and inverse proportionality. This study used the research and development with the Plomp model, comprising three phases. The first phase, preliminary research, involved 26 teachers and prospective teachers. The second phase, development or prototyping, engaged three experts and three students. The third phase, assessment, was conducted through trial testing with 31 participants in the experimental class and 31 participants in the control class. Data collection techniques included questionnaires, surveys, observations, tests, and interviews. Data processing was conducted using descriptive statistics. The results of the study indicate that the developed RME learning tools integrated with agricultural activities fulfills the criteria of valid, practical, and effective. The validity criteria were achieved with scores of 3.77 for the teaching module, 3.81 for the LKPD, 3.84 for the learning achievement test, and 3.87 for the instruction manual. The practicality criteria were met with a learning implementation rate of 95% (very good), and student activity reaching 84.9% (active). Additionally, student and teacher response questionnaires showed positive feedback, with scores of 95.48% and 100%, respectively. The effectiveness criteria were achieved with an average N-Gain score of 0.65 (moderate) and the experimental class achieved higher average scores than the control class. This study implies that RME integrated with agricultural activities can be recommended for mathematics teachers to support numeracy teaching.

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.

Abstract

Mathematics is an important foundation in developing critical and logical thinking skills, which are reflected through mathematical literacy. However, PISA 2022 scores show that Indonesian students' mathematical literacy is still below the international average, with the main weakness in solving HOTS questions. This qualitative research aims to analyze the relationship between self-regulated learning (SRL) and students' mathematical literacy in solving HOTS problems related to System of Linear Equations of Three Variables (SPLTV) at Singa Putih Munfaridin Islamic Boarding School, Pasuruan. Data were collected through HOTS tests, SRL questionnaires, and interviews with grade X students who were grouped into three SRL categories: low, medium, and high. The results showed that students with high SRL could formulate problems efficiently, apply systematic strategies, and interpret solutions independently. Medium SRL students have difficulty in applying concepts due to inaccuracy and also fail to independently verify solutions, with conclusions often adapted from classmates. Low SRL students only reached the formulation stage and failed at the application and interpretation stages. These findings reinforce Zimmerman & Schunk's theory that SRL involves a cycle of planning, monitoring and self-evaluation.

Abstract

Differential calculus problem requires the ability to connect various mathematical ideas, making mathematical connection ability an essential skill. Research indicates that prospective mathematics teachers demonstrate varying levels of mathematical connection ability. This study aimed to describe the characteristics of prospective mathematics teachers’ mathematical connection ability when solving differential calculus problems. An exploratory qualitative approach was employed involving 61 prospective mathematics teachers enrolled in a differential calculus course at a university in Indonesia. Data were collected through a written differential calculus problem and semi-structured interviews. The written responses were analyzed using five mathematical connections indicators, each scored on a scale of 0–20, to classify participants into strong, moderate, and weak levels. Interview data were used to investigate the processes and factors underlying the emergence of different mathematical connection types. The analysis revealed four types of mathematical connections: part–whole, different representation, procedural, and implication connections. Prospective mathematics teachers with strong mathematical connection level were able to coherently integrate geometric concepts, representations, and calculus procedures by effectively connecting prior knowledge, such as right circular cone geometry and triangle similarity, with new knowledge, particularly the chain rule. In contrast, those with weak mathematical connection ability exhibited fragmented or incorrect prior knowledge, leading to inappropriate representations, flawed mathematical models, and difficulties in applying calculus concepts logically. These findings highlight that the success of differential calculus problem solving depends not only on procedural proficiency but also on the quality of mathematical connections constructed between prior and new knowledge.

Abstract

Mathematics learning is essential for strengthening students’ logical reasoning and numeracy skills, particularly in abstract topics such as sequences and series; however, instructional practices in Islamic boarding schools often remain procedural and insufficiently contextualized, creating a gap between theoretical recommendations of meaningful learning and classroom reality. This study aims to develop and evaluate RME-based learning tools for sequences and series assisted by MathCityMap to determine their validity, practicality, and effectiveness in a pesantren context. The research employed a 4D development model consisting of Define, Design, Develop, and Disseminate stages. Implementation involving an experimental class and a control class, each comprising 34 students. Data were collected through expert validation sheets, observation instruments, questionnaires, interviews, and numeracy pretest-posttest assessments. The results show that all learning tools achieved valid criteria, with average expert scores above 3.75 on a four-point scale. Practicality was confirmed by 95% implementation fidelity, 84.9% active student participation, and highly positive teacher and student responses. Effectiveness testing revealed a moderate N-gain score of 0.65 in the experimental class compared to 0.54 in the control class, with an independent samples t-test indicating a significant difference (Sig. = 0.049 < 0.05). These findings demonstrate that integrating Realistic Mathematics Education with MathCityMap enhances conceptual understanding, engagement, and numeracy achievement in sequences and series learning within Islamic boarding schools.

Abstract

Concrete learning media are very important for children with special needs because they can improve understanding through visualization and engaging message delivery. Based on observations at Jember Special School Type C (Education and Care Centre), learning media are rarely used, especially when teaching integer material. This study aims to describe the process and outcomes of developing a pop-up book learning medium tailored to the different types of children with special needs, ensuring its validity, practicality, and effectiveness. The study employs a modified 4-D development model within a Research and Development (R&D) framework. Data were collected through validation sheets, user response questionnaires, interview guides, and learning outcome tests. Three methods of data analysis were used: validity analysis, practicality analysis, and effectiveness analysis. The validation results showed average scores of 3.67, 3.69, and 3.54 for learning media designed for students with intellectual disabilities, physical disabilities, and visual impairments, respectively, which are categorized as valid. The media were then tested on nine students at Jember Special School Type C, consisting of seven students with intellectual disabilities, one student with visual impairment, and one student with physical disability. Practicality analysis was conducted based on student and teacher response questionnaire scores, which were 80.25% and 80.75%, respectively, indicating a good level of practicality. The learning outcome test showed a 100% mastery level, indicating that the learning media met the criteria for effectiveness. This research is expected to serve as a reference for other researchers who wish to develop similar instructional media or further develop pop-up book learning media for other types of children with special needs. Media pembelajaran konkret sangat penting bagi anak berkebutuhan khusus karena dapat meningkatkan pemahaman mereka melalui visualisasi dan penyampaian pesan yang menarik. Berdasarkan observasi di SLB-C TPA (Taman Pendidikan dan Asuhan)  Jember, media pembelajaran jarang digunakan, terutama saat mengajarkan materi bilangan bulat. Penelitian ini bertujuan untuk mendeskripsikan proses dan hasil pengembangan pop -up book sebagai media pembelajaran berdasarkan jenis ABK yang valid, praktis, dan efektif. Penelitian ini menggunakan model pengembangan 4-D yang dimodifikasi dalam kerangka R&D. Pengumpulan data dilakukan melalui lembar validasi, angket respon pengguna, pedoman wawancara, dan tes hasil belajar. Terdapat tiga metode analisis data yaitu analisis kevalidan, analisis kepraktisan, dan analisis keefektifan. Hasil validasi menunjukkan skor rata-rata untuk media pembelajaran tunagrahita, tunadaksa, dan tunanetra sebesar 3,67; 3,69; dan 3,54 yang dikategorikan valid. Media tersebut kemudian diuji coba pada sembilan peserta didik di SLB-C TPA Jember, terdiri dari tujuh peserta didik tunagrahita, satu peserta didik tunanetra, dan satu peserta didik tunadaksa.
