Pengembangan Bahan Ajar Berbasis Pmri Pada Materi Penyajian Data Di Sekolah Dasar
This research aims to produce PMRI-based teaching material development products for data presentation materials in elementary schools that are in accordance with valid and practical characteristics. The method used in this research is the Research and Development development method with the Plomp model. The development stage carried out is the Preliminary Research Phase. Prototyping Phase, and Assessment Phase. The teaching materials developed by researchers were validated by 3 experts consisting of material experts, media experts and language experts. Meanwhile, practicality can be seen from the practicality questionnaire for teachers and students given by researchers during small group trials. The data collection techniques used by researchers in this research were interviews, observation and questionnaires. The data obtained from this data collection is then processed using quantitative analysis techniques and qualitative descriptions. Based on the validation results, the developed teaching materials have valid (feasible) criteria with an average percentage of 93.93%. Meanwhile, the practicality of teaching materials based on the teacher practicality questionnaire was 94.97% with very practical criteria, and based on the student practicality questionnaire it was 85.58% with very practical criteria. Based on the results of this research, it can be concluded that PMRI-based teaching materials for presenting data in elementary schools have met the valid and practical criteria, which means they can be used in learning.
