    Measuring the impact of academic development courses in first-and second-year chemistry
    (South African Chemical Institute, 2013) Smith, Leonard C
    This paper uses multivariate analysis to estimate the impact of educational interventions in the first-year academic development chemistry courses on students' final course marks. The cohorts for seven years are pooled, which generates a more robust set of results than was previously the case. To counter the sample-selection problem that arises as academic development students are placed onto the academic development programme, a selection of control variables is included in the estimations. The results suggest that the educational interventions in the first year had a positive impact on academic development students' performance, relative to mainstream students, in both the first- and second-year courses. The implications of the results for education policy and research are considered.

    Measuring the impact of educational interventions on the academic performance of academic development students in second-year microeconomics
    (Wiley, 2012) Smith, Leonard C; Ranchhod, Vimal
    This paper analyses the impact of educational interventions made in the first- and second-year microeconomics courses on academic development students' final mark in the second-year course. It also addresses issues of methodology, specification, and statistical analysis with respect to other studies in the field. The results suggest that the educational interventions in the first year had a positive impact on the academic performance of the academic development cohort, relative to the mainstream cohort for the first period (2000-2002). The results also suggest that the educational interventions introduced in the second period (2003-2005), in the form of voluntary workshops, improved the academic performance of the academic development and mainstream cohorts.

    Measuring the impact of educational interventions on the academic performance of black academic development students
    (Southern African Comparative and History of Education Society, 2012) Smith, Leonard
    This article uses statistical analysis to estimate the impact of educational interventions in the first and second-year microeconomics courses on black academic development students' examination and final course marks. The results suggest that the educational interventions in the first and second years had a positive impact on the academic performance of the academic development cohorts, relative to a comparable group of mainstream students, in both the first and second-year courses. The results imply that the impact of interventions is more pronounced in respect of black students, and that the determinants of academic performance differ for black students relative to the student body as a whole. Finally, the implications of the results for education policy and research are considered.
