Given the growing demand of the use of ICT in the classroom, there is still the dialectical method of whether the traditional or blended teaching is more effective in the classroom. Using a quasi-experimental method, this study explores the comparison between the traditional and blended teaching with the use of YouTube in an ESL classroom as part of the blended teaching method. The study was conducted in the basic department of one private school in Laguna, with Grade four students as respondents. From the pair result using value and p-value, pre-tests of both groups show no significant difference while the post-tests show a significant difference. However, details show that the scores of the traditional group show a bigger improvement compared to the group that used blended teaching. The study showed a disquieting revelation from the pre-test and post-test scores. Thus, the traditional type of teaching is more effective for the students rather than those who are exposed to YouTube.
