An outcomes-based approach to student learning is a recurring education reform model. It is a student-centered learning philosophy that focuses on empirically measuring student performance, that are called outcomes. Unlike many pedagogical models, such as project-based learning, OBASL does not specify or require any particular style of teaching or learning. Instead, it requires that students demonstrate that they have learned the required skills and content.
Constructive Alignment is a learning and teaching principle devised by John B. Biggs. It basically states that the intended learning outcomes, the learning activities and the assessment tasks in a programme/course must be properly aligned. Thus the intended learning outcomes (what do we want the learners to know?) must be supported by the correct use of learning activities (how will the learners learn?) and the assessment tasks including the languages employed (how will we know the learners have learnt?).
