<![CDATA[This study aims to develop learning tools with PMRI approach on SPLTV material for class X SMA/MA. The learning tools developed were assessed based on their validity and practicality. This type of research is development research with the Plomp development model, namely the initial investigation, development or prototyping stage and the assessment stage. At the initial investigation stage, needs analysis, curriculum analysis, concept analysis, and student analysis were carried out in order to obtain the characteristics of the form of learning tools developed. At the development/prototyping stage, a prototype learning device design in the form of RPP and LKPD is made using the PMRI approach for SPLTV material. The prototype used will go through formative evaluation such as self-evaluation and evaluation with experts to get a valid prototype. Furthermore, at the last stage is the assessment stage, at this stage the goal is to get the practical criteria for the LKPD prototype after conducting an individual evaluation. In this study, it was carried out when the pandemic was endemic, so in this study there were several stages that could not be carried out properly. This research was only carried out until the stage of development/prototyping of the one-on- one evaluation section. The conclusion of this research is that learning tools using the PMRI approach on SPLTV materials, namely RPP and LKPD, can be said to be valid and practical.
