The Effect of Open-Ended Approach on Automotive Electricity Learning in SMK Negeri 3 Makassar

This study aims (1) to find out the students' capabilities in the closed-ended teaching method; (2) to find out the students' capabilities in the open-ended teaching method with a scenario; (3) to find out whether there is an effect of the open-ended teaching method with a scenario on the students' capabilities to solve automotive electrical system problems with problem-based scenarios. The research subject involved a whole class (consisting of 25 students) selected by the purposive sampling technique. The data were collected through observation, tests, interviews, and documentation, then analyzed with descriptive statistical analysis of percentages, frequency distribution tables and hypothesis testing with nonparametric statistical analysis, Mann Whitney test with SPSS-PC 20.0 for windows. The results of the data analysis showed that: (1) the students' capabilities to assemble an automotive electrical system (closed-ended teaching method) was 88%, (2) the students' capabilities to solve automotive electrical problems with a problem-based scenario (open-ended teaching method in a scenario) was 72 %, (3) the effect of the students' capabilities in assembling electricity (closed-ended teaching method) was higher than the students' capabilities to solve electrical problems (scenario of open-ended teaching).
