A survey involving 280 students selected through stratified sampling was conducted to evaluate their mastery of HOTS, focusing on their ability to analyze, evaluate, and apply scientific concepts. Results indicated a moderate level of proficiency, highlighting gaps in independent application and creative problem-solving.
