Abstract

Visual representation is crucial for enhancing students' conceptual understanding of fractions and correcting misconceptions. This explanatory-sequential mixed study assessed Indonesian preservice mathematics teachers' perceptions, self-efficacy, and implementation competencies using visual representations in fraction learning and identified gaps among these three aspects. A total of 251 students from three study programs participated in a validated online survey (α = 0.89). Quantitative data were analyzed using descriptive statistics. Seven participants were then purposefully selected for semi-structured interviews; transcripts were analyzed using Braun & Clarke's six-stage thematic analysis with researcher triangulation. The results showed that although prospective teachers had a very high perception of the pedagogical value of visual representations (M = 4.41; SD = 0.153; 78.9% agreed/strongly agreed), their self-efficacy level was only in the moderate category (M = 3.21; SD = 0.617), with only 28.3% showing high efficacy, and 61.3% were in the medium category. Implementation competence was even lower, with only 17% of participants being able to select and explain visual models pedagogically and 27.8% meeting the sufficient criteria in the teaching reasoning test. The combined analysis of quantitative and qualitative data confirmed the existence of a systemic gap between strong conceptual understanding and limited practical skills, which was mainly caused by uncertainty in model selection, minimal misconception-oriented practical experience, and weak pedagogical reflection. Integrating high-fidelity micro-teaching, representational scenario-based simulations, and video reflections is recommended to enhance self-efficacy and implementation competency.Visual representation is crucial for enhancing students' conceptual understanding of fractions and correcting misconceptions.This explanatory-sequential mixed study assessed Indonesian preservice mathematics teachers' perceptions, self-efficacy, and implementation competencies using visual representations in fraction learning and identified gaps among these three aspects.

Abstract

Background - Creative thinking skills are an important ability in 21st century learning, especially in mathematics as part of higher order thinking skills. Purpose - This study aims to analyze the effect of Problem Based Learning (PBL) on aspects of students' mathematical creative thinking skills, namely fluency, flexibility, originality, and elaboration. Method/approach - This quantitative research used a quasi-experimental approach with a pretest-posttest control group design which was carried out for 1 month. The sample consisted of 32 students of class VIII-10 and 31 students of class VIII-11 of SMPN 1 Bandar Lampung who were selected by purposive sampling. Findings -The Mann Whitney U Test results showed that students who learned with PBL experienced a more significant increase in mathematical creative thinking skills than students who learned conventionally, especially in certain aspects. The application of PBL not only improves creativity in general but also strengthens the originality and flexibility of students' thinking in mathematical problem solving. The strength of this study lies in the in-depth analysis of the effect of PBL on specific aspects of mathematical creativity, not just the overall improvement. Conclusions - This study also provides empirical evidence of the effectiveness of PBL in improving higher order thinking skills at the junior high school level. Novelty/Originality/Value - Thus, PBL is proven to have an effect on students' mathematical creative thinking skills.

Abstract

Mathematical representation ability is the competence to present mathematical ideas in symbolic, visual, or verbal forms. This descriptive qualitative research aims to analyze students' errors in solving statistics problems based on mathematical representation ability, conducted through a literature study. The results indicate that students still have difficulty representing mathematical ideas (symbolic, visual, verbal). Key errors include conceptual errors (selecting formulas), inaccuracy in charts/diagrams, and inability to connect the data context with its representation. The contributing factors are the lack of conceptual understanding and a focus on procedures. This finding is expected to serve as a reference for teachers to strengthen students' mathematical representation ability, particularly in statistics material.

Abstract

Salah satu justifikasi membangun kreativitas pemanfaatan TABULAMPOT (tanaman buah dalam pot) pada masyarakat di Desa Hanura adalah untuk meningkatkan konsumsi pangan yang bersumber dari buah dengan prinsip bergizi, berimbang, dan sehat serta memanfaatkan pekarangan rumah, sehingga pertanian organik juga dapat diterapkan pada masyarakat Desa Hanura dengan tujuan untuk meningkatkan daya tahan tubuh agar terhindar dari virus dan bergaya hidup sehat dengan mengkonsumsi buah. Tujuan kegiatan pengabdian adalah memperkenalkan dan mempraktekkan penanaman berbagai macam jenis tanaman jambu dalam pot untuk masyarakat Desa Hanura sehingga dapat memanfaatkan pekarangan rumah lebih efisien. Sosialisasi ini diharapkan dapat dipraktekkan di pekarangan peserta pelatihan sehingga tercapai penghijauan yang berkelanjutan. Pemanfaatan pekarangan dengan menanam buah dalam pot dapat dilakukan untuk pemenuh kebutuhan rumah tangga pemiliknya. Disamping itu menanam buah di pekarangan dapat melestarikan lingkungan karena oksigen yang dihasilkan tanaman tersebut. Rangkaian kegiatan pengabdian yang akan dilaksanakan adalah sebagai berikut: persiapan bahan dan alat pengabdian, koordinasi strategi waktu ke lokasi pengabdian, penyemaian dan pemeliharaan, pemindahan benih ke polibag dan aklimatisasi, survey ke Desa Hanura dan pengurusan administrasi, pelaksanaan pelatihan dan pembuatan laporan. Pemberdayaan masyarakat yang akan dilakukan adalah dapat meningkatan pengetahuan dan keterampilan masyarakat Desa Hanura dalam budidaya tanaman buah dalam pot (TABULAMPOT) dengan memanfaatan lahan pekarangan di sekitar rumah serta membangun kreativitas ibu-ibu rumah tangga di Desa Hanura. Masyarakat Desa Hanura memiliki peluang untuk melakukan wirausaha tabulampot karena Desa Hanura merupakan Desa yang berbatasan denga Kota Bandar Lampung yang merupakan Kota yang banyaknya perumahan dan perkantoran sehingga Desa Hanura berpotensi menjadi sasaran untuk penjualan tabulampot. Kegiatan penyuluhan dan praktik berjalan dengan lancar, diskusi pada saat kegiatan berlangsung sangat baik dan interaktif, masing-masing peserta aktif mengajukan pertanyaan seputar budidaya dan wirausaha tabulampot. Untuk mendapatkan tabulampot yang berbuah lebat atau berproduksi baik, tidak boleh menggunakan stek atau bibit yang berasal dari tanaman yang belum pernah berbuah.

Abstract

Mathematics is an abstract discipline that requires higher-order thinking skills, particularly mathematical critical thinking, to be meaningfully understood. However, students’ mathematical critical thinking skills in Indonesia remain relatively low. This study aimed to examine the effect of the Guided Inquiry learning model on students’ mathematical critical thinking skills. The population of this study consisted of all eighth-grade students at a junior high school in Lampung Province, totaling 192 students distributed across six classes (VIII-A to VIII-F). The sample was selected using a cluster random sampling technique, resulting in 25 students from class VIII-D as the experimental group and 27 students from class VIII-B as the control group. This study employed a pretest–posttest control group design. Quantitative data were collected through essay-type pretests and posttests. Based on the results of the hypothesis testing using the Mann–Whitney U test at a significance level of α = 0.05, the median N-gain of students’ mathematical critical thinking skills in the Guided Inquiry group was higher than that of students who experienced conventional learning. These findings indicate that the application of the Guided Inquiry learning model has a positive effect on improving students’ mathematical critical thinking skills.
