A fundamental change in the learner is the main objective of teaching. To secure the transfer of knowledge, teachers should employ the most effective teaching techniques that are tailored to certain objectives and skills. One of the active learning methods is the Gallery Walk Technique. Students can learn new information, organize it meaningfully, and have the chance to describe it to their peers. As a result, it places a strong emphasis on peer interaction and encourages students to study on their own rather than depending solely on teachers to impart knowledge. This study aims to find out how effective is Gallery Walk Activities if it is used in teaching Social Studies particularly World History. Thus, the study determined that students prefer using Gallery Walk Activities during discussions since they are thought as very high. In tests of cognitive skills, they are all considered proficient. It was thought that they had a high degree of interest in learning social studies. On the other hand, the students perceived themselves as having a very high in terms of attitude for learning and functioning in groups. A corrolary of these findings would suggest that the researcher should explore more features of gallery walk that can be still added to enhance the learning experience of the students that would greatly affect their level of interest and attitude towards discovery learning. In addition, the researcher should further explore on the components of gallery walk that could achieve the highly proficient level of scores for the students.
