Development of a Self-Directed Learning Model Based on Independence with a Differentiation Approach to Improve Higher Order Thinking Skills of Vocational High School Students in North Bengkulu

The aim of the research is to produce a Self-Directed Learning model based on independence with a differentiation approach to improve the higher order thinking skills of State Vocational School students in North Bengkulu. The research uses the Research and Development method with a 4-D development model design consisting of definition, design, development and dissemination. The sample was chosen randomly and purposively sampling. Data collection uses questionnaires, interviews, validation and documentation. The results obtained in the research are an independence-based Self Directed Learning model that suits the needs of students at SMK Negeri 2 and SMK Negeri 5 North Bengkulu. The feasibility of the Independence-based Self Directed Learning model was validated by expert validators, vocational basics subject teachers. The expert validation results obtained an average of 0.92 so it was declared valid and suitable for use. The effectiveness of the independence-based Self Directed Learning model in the knowledge transfer aspect of the N Gain Score analysis obtained a score of 0.49. The N-gain Score category was in the medium category, so it was declared effective. The results of the t test analysis were 1.6686, which shows that there is a difference between the experimental class and the control class, namely that the Self-Directed Learning model is better than the previous learning model. The percentage results for the critical thinking aspect before the Self-Directed Learning model was implemented was 58.05%, while after the independence-based Self Directed Learning model was implemented, it increased to 81.45%. In the problem-solving aspect it increased from 55.91% to 67.20%.
