This study aimed to: 1) Identify reading strategies used by Malaysian secondary students. 2) Investigate the effects of teaching self-questioning reading strategies on improving students' questioning abilities. 3) Determine if self-questioning strategies improved reading comprehension. The researcher administered questionnaires, conducted tests, and analyzed students' questions to measure reading strategies, questioning skills, and comprehension. Preliminary results from 8 students showed that most used global reading strategies and self-questioning increased implicit questioning beyond the text. The full study involved randomly sampling 118 students to evaluate the effectiveness of self-questioning for reading skills.
