This is a comparison of Instructivist and constructivist pedagogical approaches and their applications in different situations, which make clear the comparative advantages of both approaches. Instructivist learning, places the teacher in authority while the constructivist shifted authority to no one in particular but shared responsibilities between learner and teacher in such a manner that the teacher no longer assumes the responsibilities of the passage of information/knowledge to the learner but only guides him to discover the "objective truth" out there and in the attainment of learning objectives. Teaching and Learning process was redefined in the light of "new" understanding in teaching and learning and practical applications of these pedagogical approaches were considered. I presented a study guide (Appendix 1) as an example of socio-constructivist pedagogy where emphasis in on learning rather than on teaching.
