It is a study of the Effectiveness of Storytelling-Based Instruction to Enhance English Listening and Speaking skills of Sixth Grade Students. The main results of this paper were to examine the effectiveness of storytelling-based instruction to develop sixth grade students’ English speaking and listening ability. The storytelling method, according to Ellis and Brewster (2002), is one way to encourage students to learn English while having fun building confidence. The research results can be employed by teachers looking for techniques to improve their teaching methods and enhance their students’ speaking and listening skills. The researcher found a number of studies investigating the effectiveness of using storytelling, but most of them focused only on listening. However, the researcher found no studies that specifically compared differences in English proficiency between students studying with and without storytelling-based instruction focusing on both listening and speaking skills in Thai schools at any level.
