What is outcome based education?
Outcome Based education is a learning theory which focuses on the skills and results achieved by the student as the most important aspect of education. It finds the mark/grade based educational system inefficient, and does not rely on the conventional teaching methods.
OBE believes, instead of rankings and exams, the use of assessments, opportunities and classroom experiences should all provide necessary support for the students to achieve their goals. By the end of the educational experience, each student should have achieved the goal. There is no single specified style of teaching or assessment in OBE; instead, classes, opportunities, and assessments should all help students achieve the specified outcomes.The role of the faculty adapts into instructor, trainer, facilitator, and/or mentor based on the outcomes targeted.
