Developing self-efficacy in making career decisions Through a set of guided activities combined with self-directed learning techniques. of Mathayom 4 students at Maha Vajiravudh School, Songkhla Province

Abstract

This study aimed (1) to compare students’ self-efficacy in career decision-making before and after participating in a guidance activity package integrating self-directed learning techniques, and (2) to compare students’ self-efficacy in career decision-making after participating in a guidance activity package integrating self-directed learning techniques against the 80 percent benchmark. The sample consisted of 38 Grade 10 students from Mahavajiravudh School, Songkhla Province, enrolled in the first semester of the 2025 academic year, selected through cluster sampling. The research instruments included (1) a guidance activity package combined with self-directed learning techniques, with content validity indices ranging from 0.67 to 1.00, and (2) self-efficacy in career decision-making scale, with content validity indices ranging from 0.67 to 1.00. Data were analyzed using mean, standard deviation, percentage, and t-test.

The study found that students’ self-efficacy in career decision-making after the intervention (  = 13.16, S.D. = 0.95) was significantly higher than before the intervention (  = 7.71, S.D. = 1.31) at the .01 level of significance. Additionally, students’ post-intervention self-efficacy scores exceeded the 80 percent benchmark, with 100 percent of participants achieving scores above the specified criterion. These findings indicate that the integration of guidance activities with self-directed learning techniques can effectively enhance students’ self-efficacy in making career decisions.
