Students in teacher education programs often experience difficulties in understanding statistical concepts due to their abstract nature and limited connection to real-world contexts. Nevertheless, statistics serves as a fundamental foundation for developing quantitative thinking skills in science education. This study aimed to develop the KIMATIKA Student Worksheet (Lembar Kerja Mahasiswa/LKM), which integrates mathematics and chemistry concepts in the Educational Statistics course to enhance students’ quantitative understanding. The study employed a Research and Development (R&D) method by adapting the ADDIE model and was conducted up to the development stage. The results of expert judgment validation indicated that the KIMATIKA worksheet demonstrated a very high level of feasibility. The material experts’ evaluation yielded an average score of 4.74 with an ideality percentage of 94.71% (Very Good), while the media experts’ evaluation resulted in an average score of 4.81 with an ideality percentage of 96.25% (Very Good). In addition, students’ evaluations produced an overall average score of 4.58 with an ideality percentage of 91.51%. These findings indicate that the KIMATIKA worksheet is substantively sound, well-structured in its presentation, linguistically appropriate, and visually effective, and it received very positive responses from students in its implementation.
