Abstract

This study aims to describe elementary students’ procedural fluency in solving fraction addition problems using the built-in definition fraction media. Fraction operations are often challenging for students, particularly when determining common denominators and applying calculation procedures accurately. These difficulties are commonly associated with weak procedural understanding and limited opportunities to use concrete learning media. This descriptive study involved 30 fourth-grade students from SDN 204 Palembang who had previously learned basic fraction concepts. Data were collected through a written test consisting of three levels of procedural fluency tasks and supported by interviews to explore students’ reasoning processes. The results show that 47% of students were able to solve fraction addition problems with denominators (Level 1), 33% managed tasks involving adjustment of one denominator (Level 2), and only 13% successfully solved problems requiring the determination of the least common multiple of denominators (Level 3). These findings indicate that students’ procedural fluency development is not linear but constrained at transition points from concrete visual manipulation to abstract procedural reasoning. While the built-in definition fraction media effectively supported early procedural stages by strengthening visual–procedural connections, it was less effective in facilitating higher-level abstraction required for complex fraction operations. The study contributes to procedural fluency literature by identifying specific procedural transition points where students begin to experience difficulties.

Abstract

Pembelajaran konsep distribusi Bernoulli masih dirasakan abstrak oleh mahasiswa sehingga diperlukan media konkret yang dapat menjembatani pemahaman antara teori dan pengalaman empiris. Penelitian ini bertujuan mengembangkan media Bernoulli Box berbantuan LKPD untuk mengenalkan konsep dasar Distribusi Bernoulli serta mengetahui validitas dan kepraktisan produk yang dikembangkan. Metode penelitian menggunakan Design Research tipe Development Studies yang meliputi preliminary phase dan prototyping phase melalui self-evaluation, expert review, one-to-one, dan small group. Subjek penelitian yaitu sembilan mahasiswa semester 1 Program Studi Pendidikan Matematika Universitas Sriwijaya yang dipilih secara purposive. Data dikumpulkan melalui walkthrough, lembar validasi, observasi, tes dalam LKPD, wawancara, dan angket kepraktisan, kemudian dianalisis secara deskriptif. Hasil validasi ahli menunjukkan bahwa Bernoulli Box dan LKPD memiliki validitas isi, konstruk, dan bahasa yang baik. Uji one-to-one dan small group menunjukkan bahwa mahasiswa mampu mengikuti aktivitas dalam LKPD secara mandiri dan memahami dua kemungkinan hasil percobaan Bernoulli dengan benar. Hasil angket kepraktisan memperoleh persentase 98,08% yang termasuk kategori sangat praktis. Dengan demikian, media dan LKPD yang dikembangkan layak digunakan sebagai alternatif pembelajaran untuk memperkuat pemahaman konsep Distribusi Bernoulli.

Abstract

In digital era, students are expected to have 21st century skills to face global challenges. One of the learning models that support 21st century skills is Project Based Learning (PjBL). This research is descriptive research to describe the implementation of mathematics learning with the PjBL model in the Basic Statistics course. Fourteen students who took the Basic Statistics course were the subjects in this study. The project is a Basic Statistics project that integrates data presentation material, frequency distribution, centering measures, and data distribution measures. Data were collected using interviews, observations, self-assessment, oral presentation, peer review and final report. The implementation of learning is carried out online using google classroom, google form, zoom meeting and whatsapp group. The results of the implementation of mathematics learning with the PjBL model in the Basic Statistics course can be said to be good with an average score of 82.5. Of the fourteen students who worked on the project, five students or 36% had completed the project very well. A total of nine students or 64% have completed the math project well from the stages of planning, implementation and collecting reports. In this study, Information and Communication Technology (ICT) plays a very important role in the stages of design, implementation, and final report collection in project completion.
