Development of Interactive Media to Introduce the World of Careers Based on the Android System to Improve the Career Understanding of Junior High School Students in Yogyakarta

Abstract

Interactive Android-based research for junior high school students to test its effectiveness in improving students' career understanding. This research uses a research and development approach with the ADDIE model, which consists of the analysis, design, development, implementation, and evaluation stages. The product developed is an interactive mobile application titled Mengenal Dunia Karier (Getting to Know the World of Careers), which is designed to support the three core dimensions of career understanding, namely self-understanding, knowledge about jobs, and career reasoning. The feasibility and practicality of the application were assessed through expert validation and practitioner evaluation, while its effectiveness was tested using a single-group pretest-posttest design involving 110 junior high school students in Yogyakarta, Indonesia. The expert validation results showed that the application was highly feasible, with media expert and material expert scores of 55 and 66, respectively, and practitioner assessments by five school counsellors classified the application as highly practical (scores ranging from 68 to 73). The effectiveness test showed a significant increase in students' career understanding after using the application, with the average score increasing from 59.93 (SD = 5.754) in the pre-test to 73.81 (SD = 6.617) in the post-test, resulting in an average increase of 13.88 points. A paired sample t-test confirmed that this increase was statistically significant (t = –16.399, df = 109, p < 0.001). These findings indicate that the developed Android-based interactive career guidance media is feasible, practical, and effective in improving the career understanding of junior high school students and can be used as a supporting tool for school-based career guidance services.
