The ability to ask questions is a crucial aspect of learning; however, students' questioning skills have generally been low. This study aimed to analyze and enhance the questioning ability of eleventh-grade students (class XI-1) at SMAN 1 Kuta Baro in physics learning through learning interventions. This research employed a quantitative and qualitative approach, with data collected through observation, questioning ability tests (pre-test and post-test), teacher interviews, and student questionnaires. Students' questioning ability was analyzed based on quantity (number of questions) and quality (cognitive level and effectiveness), for both oral and written questions. The results showed that teacher interventions successfully encouraged students to ask questions, leading to a 38% increase in the quantity of oral questions from the total students in the class, and a 28.63% increase in the quantity of written questions (from 234 to 301 questions). A significant increase was also observed in the quality of written questions based on cognitive level (P=0.001 with a significance level of 0.05). Although the quality of oral questions based on cognitive level remained low (31.25%), their effectiveness was remarkably high (81.25%). The dominant type of oral questions was conceptual (understanding concepts/C2), while written questions predominantly fell into the analyzing level (C4). Both students and teachers acknowledged that questioning ability was influenced by a combination of internal and external factors, including inhibiting factors, but it was proven that these abilities could be improved through learning interventions
