{"abstract":"The study aimed to determine the public speaking performance in different communicative domains of Grade 12 learners in Angono National High School, during the school year 2020-2021. The Public Speaking Guideline (PSG) was developed and validated based on the learner’s level of understanding. In rating the acceptability of the material, a partially- adapted checklist was utilized. To evaluate the public speaking performance, a researcher-made rubrics was employed and evaluated by English teachers from other schools and Angono National High School. Descriptive-developmental research method was used in the study. The participants were composed of two (2) sections of Grade 12 who were enrolled in the Online Distance Learning (ODL) modality, particularly HUMSS A and HUMSS B. The participants were selected using the equating variables in Oral Communication subject. A diagnostic test was given to assess the learners in terms of communicative domains and online communicative events used in public speaking. The Public Speaking Guideline was validated by the experts and was found acceptable in terms of objective, content, language used, usefulness and presentation. Based on the findings, it was found that the learners were able to deliver comprehensible ideas yet had difficulty on the use of articulation, modulation, gestures and movement. In addition, the study revealed that student’s interest was stimulated when exposed to various communicative event which led to a meaningful interaction that created a positive impact on learner’s speaking performance.","abstract_source":"original","authors":["Contessa Carla Alcazar"],"date":"2024-10-29","doi":"10.5281/zenodo.14005934","id":3864,"issue":2,"journal":{"issn":"2822-4353","name":"Psychology and Education: A Multidisciplinary Journal"},"pdf_sha256":"a27f73183a1c3503a72f14a8187ad917b6d1ffdc36338aabf67f2e1613d7250e","schema":"scimatic-article/1","title":"The Public Speaking Performance of Grade 12 Learners in Different Communicative Domain","volume":27}
