Ilmu pengetahuan dan teknologi yang semakin berkembang pesat menuntut manusia
untuk lebih meningkatkan kemampuan dirinya untuk dapat bersaing dalam lingkup
nasional maupun global. Tidak hanya dibutuhkan kemampuan kognitif tetapi juga perlu
softskills yang mendukung keterampilan pada abad 21. Pembelajaran berbasis STEM
(Science, Technology, Engineering, and Mathematics) merupakan salah satu
pembelajaran yang mampu melatih keterampilan abad 21 tersebut. Tujuan penelitian ini
adalah untuk mengetahui perubahan motivasi belajar siswa SMP pada pembelajaran IPA
berbasis STEM. Motivasi yang diukur mencakup 5 komponen yaitu intrinsic motivation,
self-determination, self-efficacy, career motivation, dan grade motivation. Metode
penelitian yang digunakan adalah kuantitatif dan desain penelitian pre-experimental
designs dengan menggunakan one group pretest – posttest design. Sampel penelitian ini
adalah siswa SMP kelas VIII dengan jumlah 38 siswa. Motivasi belajar siswa diukur
menggunakan instrumen yang diadaptasi dari Science Motivation Questionnaire II
(SMQ). Hasil penelitian menunjukkan bahwa motivasi belajar siswa mengalami
perubahan setelah diterapkannya pembelajaran IPA berbasis STEM. Komponen intrinsic
motivation mengalami perubahan dengan klasifikasi rendah (5,14), komponen career
motivation mengalami perubahan dengan klasifikasi sangat rendah (3,48), komponen selfdetermination
mengalami perubahan dengan klasifikasi rendah (6,93), komponen selfefficacy
mengalami perubahan dengan klasifikasi rendah (6,76), dan grade motivation
mengalami perubahan dengan klasifikasi sangat rendah (2,10). Dari hasil penelitian, dapat
disimpulkan bahwa setelah diterapkannya pembelajaran IPA berbasis STEM, secara
keseluruhan motivasi belajar siswa pada kelima komponen yang diukur mengalami
peningkatan.;--- Science and technology are growing rapidly demanding human to further enhance his
ability to compete in national as well as global scope. Not only required cognitive
abilities but also required softskill which included 21st century skills. STEM-based
learning (Science, Technology, Engineering, and Mathematics) is one of the lessons that
can train 21st century skills. This research was conducted to determine the change of
learning motivation in STEM-based science learning on junior high school student. the
measured motivational profile includes 5 components such as intrinsic motivation, selfdetermination,
self-efficacy, career motivation, and grade motivation. The research
method used is quantitative and pre-experimental designs research design using one
group pretest - posttest design. The sample of this research is the students of junior high
school class VIII with the number of 38 students. Students’ science learning motivation
profile measured using an instrument adapted from Science Motivation Questionnaire II
(SMQ). The results showed that the student’s learning motivation was changed toward
STEM-based science learning. This can be seen from the improvement (gain) of five
components of motivation that were measured. The result shows that the intrinsic
motivation component was changed with a low classification (5.14), the career motivation
component was changed with a very low classification (3.48), the self-determination
component was changed with a low classification (6.93), the self-efficacy component was
changed with low classification (6.76), and grade motivation was changed with a very
low classification (2.10). From the results of the study, it can be concluded that STEMbased
science learning can improve the learning motivation
