Abstract

Abstrak. Penelitian ini bertujuan untuk mendeskripsikan hasil belajar penjumlahan dan pengurangan dua angka menggunakan dekak-dekak pada siswa kelas I Sekolah Dasar Negeri 17 Delta Pawan Ketapang. Metode Penelitian menggunakan metode deskriptif, dengan bentuk penelitian  Penelitian Tindakan Kelas (PTK) yang bersifat kolaboratif dengan teman sejawat dan siswa kelas I dalam dua siklus tindakan. Hasil penelitian  menunjukkan bahwa kemampuan guru merancang pembelajaran matematika pada siklus I dengan rata-rata skor 2,61 dengan kategori cukup, meningkat pada siklus II menjadi 3,55 dengan kategori baik. Kemampuan guru melaksanakan pembelajaran matematika pada siklus I dengan rata-rata skor 2,89 dengan kategori cukup, meningkat pada siklus II menjadi 3,92 dengan kategori baik. Terdapat peningkatan hasil belajar yang signifikan dalam pembelajaran materi penjumlahan dan pengurangan bilangan dua angka dengan media dekak-dekak, dari siklus pertama ke siklus kedua siswa yang mencapai ketuntasan belajar dari 12 siswa menjadi 18 siswa atau mengalami kenaikan sebesar 50%.   Kata Kunci : Dekak-Dekak, Hasil Belajar, Matematika.   Abstract. This study aimed to describe the results of learning addition and subtraction of two numbers using the abacus in the first grade students of State Elementary School 17 Delta Pawan Ketapang. The research method using descriptive method, the research form Class Action Research (CAR) that is collaborative with colleagues and students in grade I in two cycles of action. The results showed that the ability of teachers to design learning of mathematics in the first cycle with an average score of 2.61 with enough categories, increased in the second cycle to 3.55 in both categories. The ability of teachers to implement the learning of mathematics in the first cycle with an average score of 2.89 with enough categories, increased in the second cycle to 3.92 in both categories. There is a significant increase in learning outcomes in learning the material addition and subtraction of two-digit numbers with media abacus, from the first cycle to the second cycle students who achieve a passing grade from 12 students to 18 students or an increase of 50%.   Keywords: Abacus, Learning Outcomes, Mathematics.

Abstract

Indonesia has reformed its assessment system from a national examination to a minimum competency assessment (AKM), focusing on literacy and numeracy skills. Such a change might significantly affect how teachers teach, especially novice ones. Hence, this study explores the strategies and challenges of six novice mathematics teachers as they prepare their students for the AKM. In this qualitative case study research, participants who were mathematics teachers, with no more than five years of teaching experience, were recruited through purposive sampling to engage in semi-structured interviews. Moreover, six lesson plans, before and after the announcement of the AKM, were collected to get a picture of how they modified their teaching and planning. The data from interviews and lesson plans were analysed through the thematic-analysis method to get two main findings. Initially, the novice teachers undertook proactive measures to prepare their students for the assessment. They employed a responsive teaching approach, adapted lesson plans, participated in professional development programmes, and conducted AKM courses. Nevertheless, their efforts were hindered by their limited teaching experience and inadequate professional development opportunities in numeracy instruction. These findings serve to enlighten educators, school administrators, and other stakeholders about the perceptions and challenges faced by teachers in light of assessment reform
