Achieving the fourth SDGs by developing students’ public speaking skills: A practice of behavioral counseling with modeling method

\nQuality education is the main focus of the fourth Sustainable Development Goals (SDGs), which specifies inclusivity in the learning process and improves the quality of students. Therefore, this research used a single subject design with an A-B-A design, engaging five 10th grade students who had low public speaking skills based on observations and guidance counselor reports. Data were collected through direct practice sessions and assessed using a public speaking practice evaluation sheet. The results showed that there was an improvement in the average scores of students’ public speaking practice from the baseline phase before intervention (A) to after intervention (A2). The average practice scores for each students during the baseline phase before intervention (A) were 38.33, 36.66, 34.3, 38.6, and 43.6. After the intervention (A2), the average scores increased to 74, 75, 69, 78.6, and 75.6. Based on these results, the introduction of behavioral counseling with modeling strategies effectively enhanced the public speaking skills of high school students. This method could help school counselors develop programs to enhance the public speaking skills of students.\n
