However, Africa's electricity generation from renewables is increasing slowly, only growing by 6% between 1985 and 2020 [3]. The contribution of solar generation is even more minor, only 2.23% as of 2020, despite having excellent conditions for PV electricity [3], [8]. SSA's long term daily power output achievable by PV exceeds 4.5 kilowatt-hours per installed kilowatt peak (kWh/kWp
This paper proposes a qualitative systems dynamics model that explains how students’ work placement experiences either enhance or hinder the growth of their occupational competency and self-efficacy. The model is developed from qualitative analysis of work placement experiences of mechanical engineering students from a South African university of technology. Findings from the analysis show that students’ occupational competency and self-efficacy could be considered emergent outcomes of interactions of the learning environment, mentor posture, mentor capacity, mentor availability, meaningfulness of work, scope of work, agency, doing work, co-participating, participation trajectory and performance trajectory. The explanation of the factors and social mechanisms that influence students’ occupational competency and self-efficacy that is offered by the qualitative systems dynamics model would enable the implementation of work placement programs in a manner that would promote rather than hinder the growth of these two indicators of student employability.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
