The curriculum extension program (CEP) of the Shell Science Centre provided group tutoring to small groups of secondary school pupils using qualified teachers. This evaluation report presents articles discussing various aspects of the program and its effectiveness. The first article by A. Ziervogel provides a review of the program. The following three articles discuss the tutoring activities in the three subject areas: physical science (P. Hobden), mathematics (P. Ntenza), and English (A. Ziervogel). A second cluster of six articles summarizes: (1) results of a mathematics test administered to program participants and non-participants (P. Ntenza); (2) results of a review test in the physical sciences to improve program quality (P. Hobden); (3) school based curriculum development using pupil writing as a starting point (A. Ziervogel); (4) findings of a statistical analysis of attendance records to examine attrition, absenteeism, and early dropouts (A. Lewy, A. Ziervogel, and P. Botha); (5) profiles of tutors and students in the program (C. Scott); and (6) matriculation results of CEP participants in comparison with non-participants (A. Lewy and P. Hobden). The final article by P. Botha looks ahead to the possibility that the Centre will continue to offer the program to secondary school students in the future. (MHD)
