The Effectiveness of the PONTA Learning Model Based on Blended Learning in Vocational High School

This study aims to determine the effectiveness of the blended learning-based PONTA learning model in vocational high schools. The model developed consists of 5 stages, namely: preparation, observation, negotiation, transfer, and apply. The trial design was carried out using a pretest-posttest group design. The test was carried out on class XII students of SMK Negeri 3 Makassar and SMK 10 Makassar. Data analysis used (1) gain score index data analysis; (2) normality analysis; (3) homogeneity analysis. The results showed that the results of testing the effectiveness of the blended learning-based PONTA learning model at SMK 3 Makassar obtained an n-gain value of 0.40 in the medium category with 81.92% learning completeness in the high category. While at SMK 10 Makassar, the n-gain value was 0.42 in the medium category with 83.24% learning completeness in the high category. Based on the research results, blended learning-based PONTA learning model in vocational high schools is effective and feasible to use to increase knowledge of occupational safety and health in the environment.
