This study focused on enhancing students’ reading comprehension through the implementation of KWL (know, want to know, and learned) strategy at the secondary level. The purpose of KWL strategy is to offer construction for stimulating and building students’ schemata, to create a determination of their reading, and to conclude what they acknowledged before. This research applied Classroom Action Research based on the model suggested by Taggart and Kemmis (1998), consisting of five stages: preliminary study, planning, implementing, observing, and reflecting. The students were asked what they know about the topic, what they wanted to know about the topic and then what they learned from the text after they had read the written text. Based on the findings of the study, this KWL strategy trained students to be brave to present in front of the class to share their ideas with their friends, and it also assured other students to keep on listening and appreciating their friends’ comprehension of the text being studied. It is, therefore, strongly suggested that the English teachers at Junior High School use the KWL strategy to improve students’ reading comprehension.
