This paper discusses in particular how to assess the validity an android-based learning multimedia developed based on the Cognitive Load Theory (CLT) for a multimedia for learning plane geometry. The validation assessment uses two kinds of validation sheet. The first is for assessing the content of the learning material that includes three aspects; (1) The feasibility of content/material, (2) The feasibility of presentation, and (3) The compatibility with CLT in which the three of these aspects are divided into eleven indicators. These concern with how the multimedia manage intrinsic, extraneous and germane cognitive load. The second is for assessing the multimedia construction by android-based media experts, which also includes three aspects, namely (1) The feasibility of visual/display, (2) The feasibility of programming, and (3) The compatibility with CLT, these three aspects are divided into thirteen indicators for assessing the cognitive load factors. The validation was conducated by lecturers in the area of geometry and multiedia The quantitative data acquired from the experts (validators) assessment results then converted into qualitative data by referencing to the value conversion table. The test results of the developed learning multimedia validity are: the average total score by the material expert is 4.07 with "Very Good" validity criteria. The average total score by a media expert is 3.66 with "Good" validity criteria. © 2019 IOP Publishing Ltd. All rights reserved.
