Penerapan Pendekatan Pembelajaran TaRL yang Terintegrasi dengan Pembelajaran Berdiferensiasi Untuk Meningkatkan Hasil Belajar Peserta Didik Mata Pelajaran Matematika Pokok Bahasan Bilangan Besar Kelas IA Semester Genap SD Negeri Tanjungrejo 5 Kota Malang

Abstract

The academic achievement of students in class 1a of SDN Tanjungrejo 5 Kota Malang in the
subject of Mathematics, especially in the topic of large numbers, shows a low level. This problem is
caused by a conventional learning approach that is not integrated, making students passive in
learning. Therefore, this research aims to address this issue by applying an innovative and integrated
learning approach. The method used in this research is the Teaching at the Right Level (TaRL)
approach integrated with differentiated learning. Students are grouped into three groups based on
their abilities and learning styles, namely proficient, moderate, and developing groups. The research
was conducted through collaborative classroom action research involving two cycles and a pre-cycle
stage. Each cycle involves planning, action implementation, observation, evaluation, and reflection.
The research sample consisted of 18 students in class 1a in the even semester. The results showed that
in the pre-cycle stage, only 5 students (27.77%) achieved learning completeness, while the others did
not. However, in Cycle I, there was a significant improvement, with 12 students (66.66%) achieving
learning completeness. In Cycle II, there was an even more significant improvement, where 17 students
(94.44%) achieved learning completeness. Furthermore, the mean results also experienced a
significant increase from 55.28 in the pre-cycle stage to 86.12 in Cycle II. Thus, this research provides
evidence that the implementation of the TaRL approach integrated with differentiated learning is
effective in improving students' learning outcomes in Mathematics. Additionally, this research also fills
the gap in previous research at SDN Tanjungrejo 5 Kota Malang. It is hoped that this research can
provide solutions to improve students' learning outcomes and contribute to the development of
innovative and integrated learning approaches more broadly.
