<![CDATA[This research aims to conduct a validation analysis of the concept achievement module assisted by wordwall media on the material of liquid pressure. The research method used is quantitative descriptive. The validation analysis technique uses the Aiken's V formula. Data validation was obtained from 3 assessors. Validation uses four answer criteria from the Likert scale, namely very good, good, quite good, and less good. The results of the validation test of 21 module items from 3 raters obtained a V value of 0.94 with high criteria. The results of the study can be concluded that the module is feasible and valid if applied to the learning process. The Concept Achievement module assisted by wordwall media can be said to be effective in supporting the learning process in achieving students' conceptual understanding of the material of liquid pressure.]]>
