In Vietnam, learning and mastering a foreign language has become increasingly common. However, achieving fluency and proficiency in language use remains a challenge for many learners, particularly in English. While some students demonstrate a strong command of grammatical structures, they often struggle with communication, specifically in listening and speaking skills.

As an educator, my primary objective is to equip students to use English effectively. Among the various language skills, listening comprehension poses a significant challenge for learners. This study, conducted at Thai Nguyen University of Technology (TNUT), aimed to identify an effective learning approach to improve students’ listening comprehension skills in English. The research employed the Bottom-up Technique in listening instruction and conducted a comparative experiment with two student groups (K47Y and K47K1). A quantitative research methodology was adopted, drawing on data from three tests and a structured questionnaire. Comments, observations, comparisons, recommendations, and conclusions are grounded in empirical findings.
