<![CDATA[This examination means to test the adequacy of science learning strategies in working on understudies' more elevated level reasoning. This exploration is advancement research utilizing the ADDIE (Investigation, Plan, Improvement, Execution, Assessment) methodology. In view of the exploration results, it was reasoned that the advancement of HOTS-based learning instruments with the assistance of the issue based learning model was effective. The improvement method utilizes the ADDIE (Examination, Plan, Advancement, Execution, Assessment) technique. The approval results with parts of content reasonableness, language reasonableness, and show appropriateness got a decent reaction from the validator. Aside from that, the typical understudy reaction to HOTS issue based learning is generally excellent, and assuming that you look at understudy scores when executing HOTS issue based learning, you can see a huge increment. This implies that this learning instrument is reasonable for use to further develop understudies' HOTS capacities. The consequences of this examination are as illustration plans, LKPD, evaluation instruments as HOTS questions, and an expansion in understudies' HOTS capacities which should be visible from the aftereffects of looking at understudy scores when executing the HOTS questions. . based learning model. Aside from that, understudies become familiar with thinking at a more significant level so they can tackle each numerical issue given. The attributes of the issue based HOTS learning item being created are 1) estimating significant level abilities to reason, requiring understudy imagination in settling HOTS questions, 2) relevantly based, and 3) utilizing different types of inquiries]]>
