Abstract

The integration of statistical software such as SPSS in higher education represents a pivotal advancement, yet limited research has systematically examined how students perceive its pedagogical usefulness and accessibility. Prior studies seldom differentiate between the cognitive and affective dimensions influencing the efficacy of SPSS-assisted learning, leaving a gap in understanding its broader impact on student engagement and competence. Addressing this gap, the present research investigates the novelty of SPSS implementation within statistics coursework, focusing specifically on student perceptions regarding its usefulness and ease of use. Employing a descriptive mixed-methods approach, quantitative data were collected from 85 respondents through a validated and reliable questionnaire comprising 13 items, complemented by qualitative insights from in-depth interviews using open-ended prompts. The findings indicate that student perceptions are predominantly favorable for both usefulness (79.21%) and ease of use (75.18%). Qualitative analysis substantiates these results, highlighting accelerated data analysis, simplified processing, and enhanced visualization as key strengths, while noting initial challenges faced by some participants. The study underscores that optimizing the educational value of SPSS necessitates comprehensive instructional support, thereby informing future curricular improvements designed to foster numeracy and analytical proficiency in statistical learning.

Abstract

Pemahaman siswa terhadap operasi penghitungan campuran pada pecahan merupakan aspek penting dalam pembelajaran matematika di sekolah dasar. Namun, berbagai penelitian menunjukkan bahwa siswa sering mengalami kesulitan dalam menyelesaikan soal cerita yang berkaitan dengan konsep ini. Solusi tersebut dapat terjadi akibat kesalahan-kesalahan yang dialami siswa seperti kurangnya pemahaman terhadap konsep pecahan, kesalahan prosedur, dan kesulitan dalam memahami makna soal. Apabila permasalahan ini tidak segera terselesaikan, tentu akan berdampak pada proses pembelajaran. Oleh karena itu, diperlukan suatu pendekatan yang dapat dijadikan alternatif untuk menganalisis kesalahan siswa dalam menyelesaikan soal cerita. Penelitian ini menggunakan pendekatan kualitatif dengan metode studi kasus untuk menganalisis kesalahan siswa berdasarkan Analisis Kesalahan Newman. Data dikumpulkan melalui tes uraian empat soal dan wawancara untuk menggali faktor-faktor penyebab kesalahan. Hasil penelitian menunjukkan bahwa kesalahan paling dominan terjadi pada tahap penulisan jawaban akhir (32,35%), diikuti oleh kesalahan pada proses penyelesaian soal (25,49%), transformasi (18,63%), pemahaman soal (14,71%), dan pembacaan soal (8,82%). Hasil wawancara menunjukkan bahwa kesalahan disebabkan oleh kurangnya pemahaman konsep pecahan, tergesa-gesa dalam mengerjakan soal, dan minimnya penggunaan metode konkret dalam pembelajaran. Temuan ini menyoroti pentingnya pendekatan berbasis pemecahan masalah dan penggunaan media konkret untuk meningkatkan pemahaman siswa terhadap operasi hitung pecahan.

Abstract

Teachers’ self-assessment is recognized as a key mechanism for fostering professional growth and improving instructional practices. It allows educators to reflect on and develop their teaching performance autonomously. However, in the Indonesian context, there is a scarcity of self-assessment instruments that are both effective and measurable. This study employed a descriptive qualitative approach with a case study design to analyze existing teacher self-assessment instruments. Indicators from several available tools were examined and categorized using a theoretical framework comprising three core domains: knowledge of content, knowledge of pedagogy and practice, and knowledge of students. The analysis resulted in the identification of seven essential components for teacher self-assessment: (1) connecting students’ prior knowledge with new content; (2) effective delivery of instructional materials; (3) addressing students’ errors, difficulties, and misconceptions; (4) promoting active student participation; (5) building rapport among students and between teachers and students; (6) effective use of learning resources, media, and technology; and (7) selecting, using, and following up on assessments. These components were further structured across three developmental levels to reflect teachers’ growth. The proposed components serve as a foundation for developing more comprehensive and contextually relevant self-assessment instruments for teachers. By aligning self-assessment practices with pedagogical goals and classroom realities, these tools can support sustained professional development and instructional improvement.

Abstract

Mathematical problem-solving skills are essential for elementary students and can be enhanced through innovative teaching approaches. This study investigates the effectiveness of Discovery Learning and Flipped Classroom models in improving problem-solving abilities among fifth-grade students. A quasi-experimental design was employed with two experimental groups: one taught using Discovery Learning and the other using the Flipped Classroom model. The study involved 60 randomly selected fifth-grade students. Data collection was conducted using pretest and posttest assessments to evaluate mathematical problem-solving skills. The results indicate that students in the Discovery Learning group demonstrated a significantly greater improvement in their problem-solving scores compared to those in the Flipped Classroom group. The findings suggest that the interactive and exploratory nature of Discovery Learning contributes more effectively to the development of critical thinking and collaborative problem-solving skills. The study highlights the potential of Discovery Learning in fostering deeper understanding and engagement in mathematical problem-solving. While the Flipped Classroom also showed positive effects, Discovery Learning proved to have a stronger impact, suggesting its suitability for enhancing problem-solving capabilities in elementary education. Discovery Learning is more effective than the Flipped Classroom in improving mathematical problem-solving skills among fifth-grade students. These findings underscore the importance of adopting active learning approaches to strengthen critical and collaborative skills in mathematics education.

Abstract

This study aims to identify and analyze various learning obstacles encountered by eighth-grade students in understanding the topic of systems of linear equations in two variables (SLETV), using the Didactical Design Research (DDR) approach at the metapedadidactic stage. Employing qualitative methods, data were collected through diagnostic pretests and posttests, classroom observations, and in-depth interviews. The findings reveal that students face three types of learning obstacles: ontogenic, didactic, and epistemological. Ontogenic obstacles are related to difficulties in understanding algebraic symbols and representing problems within real-life contexts, while didactic obstacles arise from teacher-centered instructional methods and insufficient supporting materials. Epistemological obstacles are evident in students’ inability to apply conceptual knowledge when confronted with non-routine problems. Through DDR-based interventions—comprising prospective, metapedadidactic, and retrospective analyses—these learning barriers can be reduced, resulting in significantly improved student understanding, as reflected in enhanced learning outcome indicators. These findings highlight the importance of early detection of learning obstacles and the use of reflective practices during the metapedadidactic stage as a foundation for designing more adaptive mathematics teaching strategies that are aligned with students’ needs.
