Abstract

Peserta didik selama ini menggunakan LKPD yang masih memiliki keterbatasan dalam aspek desain dan tampilan. LKPD tersebut hanya disajikan dalam format hitam putih sehingga kurang menarik secara visual. Selain itu, LKPD tersebut cenderung digunakan secara dominan sebagai satu-satunya bahan ajar, sehingga belum mampu mendukung variasi sumber belajar yang lebih kaya pada pelaksaan pembelajaran. Studi ini difokuskan mengembangkan LKPD berbasis Problem Based Learning pada materi Statistika yang layak digunakan, ditunjukkan melalui tingkat kevalidan dan kepraktisannya, serta memiliki tampilan yang menarik dan berwarna. Riset ini mengadopsi model 4D: mendefinisikan, merancang, mengembangkan, dan menyebarkan. Penelitian ini melibatkan ahli materi, ahli desain, ahli bahasa, serta guru mata pelajaran matematika, serta 9 peserta didik kelas X SMA Negeri 11 Rejang Lebong. Temuan riset mengindikasihkan capaian indeks validitas sebesar dapat dilihat dari aspek kevalidan bahasa (0,94), media (0,85) dan materi (0,92), Berdasarkan angka tersebut, kualitas media pembelajaran dinyatakan memenuhi kriteria Sangat Valid. Secara praktikalitas, produk ini mencatatkan skor 97,1% sehingga dinyatakan masuk dalam kategori Sangat Praktis. LKPD berbasis Problem Based Learning yang dikembangkan telah memenuhi kriteria kevalidan dan kepraktisan. Dengan demikian, disimpulkan bahwa LKPD berbasis Problem Based Learning pada materi Statistika yang dikembangkan dinyatakan valid dan praktis digunakan dalam pembelajaran.

Abstract

Penelitian ini bertujuan untuk mengembangkan dan menguji validitas serta kepraktisan modul ajar matematika pada materi peluang kelas VIII yang menggunakan model pembelajaran discovery learning dan aplikasi evaluasi digital Zep Quiz. Metode yang digunakan adalah model pengembangan Plomp yang meliputi lima tahap: investigasi awal, desain, konstruksi, evaluasi, dan implementasi. Modul dirancang untuk mendukung pembelajaran kontekstual, aktif, dan kolaboratif sesuai dengan prinsip Kurikulum Merdeka. Hasil validasi oleh ahli menunjukkan bahwa modul berada pada kategori “sangat valid” dengan rata-rata skor 85,42%. Sementara itu, hasil uji kepraktisan berdasarkan respon siswa juga menunjukkan kategori “sangat praktis” dengan rata-rata skor 92%. Penggunaan Zep Quiz terbukti mampu meningkatkan keterlibatan siswa dalam evaluasi formatif. Dengan demikian, modul ajar yang dikembangkan layak digunakan dalam pembelajaran matematika di kelas VIII.

Abstract

This study analyzes mathematics teachers' perceptions of the implementation of a Project-Based Learning curriculum at SMP Negeri 11 in Bengkulu City. The transformation of the learning paradigm from teacher-centered to student-centered through Project-Based Learning (PBL) requires significant adaptation from educators. The study used a descriptive qualitative approach with semi-structured interviews, classroom observations, and documentation analysis with one seventh-grade mathematics teacher. Findings indicate that the school has not provided formal training on Project-Based Learning (PBL), but teachers have participated in independent training through webinars and the MGMP forum. Teachers have positive perceptions of the project-based curriculum implementation because it increases students' learning interest, critical thinking skills, and collaboration skills. Implementation has not been comprehensive across all materials due to limited time, resources, and supporting facilities. The project-based curriculum has a positive impact on student motivation and engagement, although individual participation varies. The study recommends the need for systematic and ongoing training support to optimize the implementation of Project-Based Learning (PBL) in mathematics learning.

Abstract

Purpose – This study examines seventh-grade students’ mathematical conceptual understanding of algebra and identifies areas of conceptual difficulty. The study responds to concerns about weak algebraic understanding, reflected in a mean daily assessment score of 49.21 at a junior secondary school in Bengkulu, Indonesia. Methodology – A descriptive qualitative design involved 36 seventh-grade students. Data were collected through a mathematical conceptual understanding test and follow-up interviews. Students’ responses were analysed across indicators of restating concepts, representing concepts, selecting appropriate procedures, and applying concepts to problem solving. Findings – No students were classified in the high category; 16 students (44.44%) were in the moderate category and 20 (55.56%) in the low category, with an overall mean score of 27.08. Achievement was highest for restating concepts (42%), followed by representing concepts (31%), using appropriate procedures (22%), and applying concepts in problem solving (13%). Interviews also identified learning environment, facilities, self-regulation, learning independence, and access to learning resources as contextual factors related to students’ difficulties. Novelty – The study provides an indicator-level diagnostic profile showing that students’ difficulties become more pronounced as algebraic understanding moves from recalling and representing concepts toward procedural selection and problem application. Significance – The findings contribute contextual evidence to international research on algebra learning by identifying a progression of conceptual difficulties that can inform diagnostic assessment and targeted instruction in comparable lower-secondary mathematics settings.
