Choice-based instructional strategies convey multi method representation of the same content in front of the learners. Students select the best alternative oftheir own choice and level. Consequently an effective learning environment may be offered by the teachers. Engagement towards development of choice-based learning strategies enhances the creativity and pedagogical competencies among the teachers. The proposed strategies will help introductory chemistry beginner’s quick determination of geometry of non-transition metal based molecules with appreciable accuracy. The efficacy of this proposed choice-based strategy has been justified by simple statistical measure.
