Abstract: A developing world like Africa inherited an educational system that laid high emphasis on what is known as the 3Rs (reading, writing, and arithmetic). This teaching/learning method was perhaps relevant then, due to the enlightenment gap that existed between learners and their instructors (Missionaries/Colonial masters). The 3Rs known as rote learning regurgitation of facts is teacher-centered that subjects learners to memorization of information for the expansion of knowledge. This learning principle mostly evaluate learners through the use of tests and examinations to ascertain their learning levels. However, as good as the 3Rs learning method is, it only prepares learners for job acquisition, not problem-solving. This paper will argue for a paradigm shift, to key in with the developed world like America and start wrestling with an educational curriculum that is learners focused; a curriculum that is concerned with the ‘how’ to think in learning than the ‘what to think.’ Urbanization, globalization, complex factories/technologies in this dispensation are calling for learning principles that can guide learners on how to move from learning assumptions to the application of daily realities of life using both the cognitive, affective and the psychomotor domains. The paper attempt to define the ‘how’ approach using. the perspective of applying critical thinking skills before drawing a conclusion. Keywords: Curriculum design, the 3Rs and the 4Cs, critical thinking, instructors and learners, reflective teaching.
