Description
Two questionnaires were administered to probe learners’ preparedness for learning mechanics in Grades 10-12. Firstly the knowledge that 1211 Grade 10 learners acquired in the theme Energy and Change in the previous school phase was determined. A second investigation probed 122 Grade 9 learners’ primordial conceptions regarding motion. The results indicated fragmented, incoherent cognitive structures with reliance on observational rather than scientific explanations. Both the investigations showed deficiencies for effective elaboration of learners’ knowledge in mechanics.
