Abstract

This study aims to measure the equality of creativity constructs among vocational school students learning structural mechanics using Multi Group Confirmatory Factor Analysis MGCFA. The MGCFA analysis was used to test the consistency of the creativity measurement structure in vocational school students in various areas of Jakarta so that the assessment results could be validly compared between school groups. The research participants consisted of students from SMKN 35 Jakarta, SMKN 56 Jakarta, SMKN 1 Jakarta, SMKN 26 Jakarta, and SMKN 52 Jakarta who had studied structural mechanics material, including forces on building structures, types of support, force analysis, force balance, and simple frame rod styles. The research instrument consists of 12 indicators that represent the dimensions of conceptual creativity and procedural creativity. The results of the analysis showed that the two factor model had a good model match with values chi square 75.997, df 53, CFI 0.967, TLI 0.959, RMSEA 0.033, and SRMR 0.036. Most indicators have a significant loading factor to their respective latent constructs. The results of the MGCFA show that the creativity construct has a relatively consistent measurement structure in vocational school students in the building sector in various areas of Jakarta. The findings of the study show that the instrument has adequate psychometric characteristics to measure student creativity consistently between groups. This research contributes to the development of engineering creativity assessment in vocational education and supports the alignment of graduate competencies with the needs of the modern construction industry.
