Bahan ajar Matematika yang dapat meningkatkan hasil belajar siswa kesulitan
belajar Matematika sangat terbatas. Bahan ajar Matematika yang selama ini
digunakan siswa kesulitan belajar Matematika sama dengan bahan ajar yang
digunakan siswa lain, sementara kemampuan siswa berbeda-beda. Tujuan
penelitian ini adalah mengembangkan bahan ajar untuk meningkatkan hasil belajar
siswa kesulitan belajar Matematika kelas 5 sekolah dasar. Penelitian ini merupakan
penelitian dan pengembangan berbasis desain didaktis (Didactical Design
Research) berdasarkan kesulitan belajar siswa dan konsep among Ki Hajar
Dewantara dengan menggunakan model pengembangan 4D (Define, Design,
Develop, Disseminate) dari Thiagarajan, S., D. S. Semmel, M. I. Semmel (1974).
Teknik pengumpulan data menggunakan angket, tes, wawancara, dan observasi.
Data hasil validasi bahan ajar dianalisis dengan menggunakan rumus Content
Validity Ratio (CVR), dan data hasil uji efektitivitas bahan ajar dianalisis
menggunakan statistik inferensial. Temuan penelitian ini adalah 1) bahan ajar
Matematika berbasis desain didaktis dan konsep among Ki Hajar Dewantara ini
layak menurut penilaian para ahli; 2) Bahan ajar Matematika berbasis desain
didaktis dan konsep among Ki Hajar Dewantara terbukti efektif dalam
meningkatkan hasil belajar siswa kesulitan belajar Matematika materi pengenalan,
penyajian, dan penafsiran data; dan 3) Bahan ajar Matematika berbasis desain
didaktis dan konsep among Ki Hajar Dewantara ini bermanfaat dan mudah
digunakan untuk meningkatkan hasil belajar siswa kesulitan belajar Matematika
materi pengenalan, penyajian, dan penafsiran data. Temuan ini dapat digunakan
sebagai bahan ajar alternatif dalam meningkatkan hasil belajar siswa kesulitan
belajar Matematika materi pengenalan, penyajian, dan penafsiran data. Penelitian
ini dapat dilanjutkan untuk mengembangkan bahan ajar mata pelajaran lainnya
untuk kesulitan belajar Matematika sekolah dasar.
Kata Kunci: Bahan ajar Matematika, desain didaktis, konsep among Ki Hajar

Mathematics teaching materials that can improve learning outcomes of students
with learning difficulties in Mathematics are very limited. The Mathematics
teaching materials that have been used by students with learning difficulties in
Mathematics are the same as the teaching materials used by other students, while
the students' abilities vary. The purpose of this study is to develop teaching
materials to improve learning outcomes of students with learning difficulties in
Mathematics in grade 5 of elementary school. This research is a research and
development based on didactic design (Didactical Design Research) based on
students' learning difficulties and the concept of among Ki Hajar Dewantara using
the 4D development model (Define, Design, Develop, Disseminate) from
Thiagarajan, S., D. S. Semmel, M. I. Semmel (1974). Data collection techniques
used questionnaires, tests, interviews, and observations. Data from the validation
of teaching materials were analyzed using the Content Validity Ratio (CVR)
formula, and data from the effectiveness test of teaching materials were analyzed
using inferential statistics. The findings of this study are 1) Mathematics teaching
materials based on didactic design and the concept of among Ki Hajar Dewantara
are feasible according to expert assessments; 2) Mathematics teaching materials
based on didactic design and the concept of among Ki Hajar Dewantara have
proven effective in improving the learning outcomes of students with learning
difficulties in Mathematics in the material of introduction, presentation, and
interpretation of data; and 3) Mathematics teaching materials based on didactic
design and the concept of among Ki Hajar Dewantara are useful and easy to use to
improve the learning outcomes of students with learning difficulties in Mathematics
in the material of introduction, presentation, and interpretation of data. This
finding can be used as an alternative teaching material in improving the learning
outcomes of students with learning difficulties in Mathematics on the subject of
introduction, presentation, and interpretation of data. This research can be
continued to develop teaching materials for other subjects for students with
learning difficulties in elementary school Mathematics.
Keywords: Mathematics teaching materials, didactic design, the concept of among
Ki Hajar Dewantara, introduction, presentation, and interpretation of data,
