This research is a component of a larger study on the creation of CPS mathematics tools for the purpose of enhancing class VIII pupils' mathematical problem-solving skills. The CPS learning paradigm is a problem-solving approach to education. The teacher's role is to steer students' efforts toward creative problem-solving and to provide subject matter or conversation topics that encourage them to think creatively. Interview instructions, checklists, and validation sheets are utilized as tools. The findings indicated that two steps should be used to determine the validity of training materials. Until begin, self-evaluation involves peers and can be continued with modest adjustments to the expert review stage. Second, the researcher conducted an expert evaluation by soliciting feedback from five experts. The findings of this study demonstrate the validity of mathematics instructional tools. © 2023 Author(s).
