This study aimed to achieve three objectives: 1) To investigate the development of speaking skills and critical thinking skills through the use of dilemma scenarios, 2) To examine the correlation between speaking skills and critical thinking skills enhanced through the use of dilemma scenarios., and 3) To explore the perceptions of undergraduate students on the efficacy of using dilemma scenarios for improving English speaking and critical thinking skills. The sample consisted of 45 undergraduate students enrolled in Daily English Listening and Speaking, the first semester of the academic year 2023 at the University of Phayao with purposive sampling, The investigation was conducted during the first semester of the academic year 2023, employing a mixed-methods approach to collect and analyze data. Results highlighted notable advancements in students' abilities, with speaking skills scores increasing from a pre-test average of 17.80 to a post-test average of 23.07, and critical thinking skills scores rising from 60.5 to 66.07. Student feedback further validated the utility of dilemma scenarios, emphasizing greater engagement, motivation, and a deeper practical understanding of the skills learned. The research underscores the significant role dilemma scenarios could play in English language education, effectively bolstering linguistic and cognitive skills. The methodology and outcomes suggest a promising direction for incorporating such interactive learning tools into teaching strategies, aiming to enrich the educational experience and skill set of learners in similar settings.
