THE EFFECTIVENESS of PROBLEM BASED LEARNING MODEL with MIND MAPPING in HEALTH LAW and ETHICS LECTURES

The challenges of the world of work in the Industrial Revolution Era 4.0 accelerated by the COVID-19 pandemic, require education graduates who have 4C competencies (Critical, Creativitythinking, Collaboration, and Communication) and HOTS (High Ordinary Thinking Skill) thinking skills. The lecture process in Health Ethics and Law at the Community Health Sciences study program FKM Unand has not been able to accommodate the needs for learning achievement (CPL) 4 C and the ability to think HOTS well.The results of interviews with 10 informants of Bachelor of Public Health revealed that the characteristics of public health ethics with the problem have not been mastered. The use of mind mapping in learning shows an increase in students' abilities by 75%, and without mind mapping only 35% (Buzan T 2009)1. This study aims to determine the level of student learning effectiveness using the Problem Based Learning Model By Using Mind Mapping. This type of research is Research and Development using the ADDIE development method (Analysis, Design, Development, Implementation, and Evaluation).The effectiveness test of the model was carried out on students with a pretest-treatment-posttest research design on the experimental class and the control class by dividing the experimental class and the control class. In drawing conclusions, statistical analysis of T-test was used on the posttest scores of the experimental class and the control class, and the gain score between the posttest and pretest scores of the experimental class. To ensure the equality of the experimental class with the control class, a pre-test and t-test analysis were carried out and the results found that there was no difference in initial ability between the two classes. From the posttest results, it was known that the average value of the experimental class = 82.73 while the control class = 69.51, and after the T-test there was a significant difference at the 95% confidence level, which means that the use of the model is effective in increasing student competence.The second analysis was carried out by looking at the gain-score between the pretest and posttest values of the experimental class, where the average value was 60.54 and 82.73. After the T-test was conducted, it was also known that there was a significant difference at 95% confidence, which means that the use of the model has been able to increase the posttest score effectively and significantly with the pretest value. So that the overall implementation of Problem Based Learning by Using Mind-mapping models is effective in improving learning outcomes.
