Implementing task-based learning in multilingual solar rooftop training: A case study from the photovoltaic laboratory – ISA STAR center, University of Havana

Task-Based Learning (TBL), a method having its roots in language instruction. This method uses authentic, real-world tasks when learners are acquiring skills. The present study reports the implementation of TBL in a multilingual setting, in a Solar Rooftop Training Program hosted at the Photovoltaic Laboratory of the University of Havana, which is also a Solar Technology Application and Resource Center (STAR – C), established by International Solar Alliance (ISA). The program is conducted at this STAR-C as part of ISA's solar capacity building initiative. The research highlights the significance of TBL for technical training programs with an in-depth explanation of the task design, its implementation and the impact on learning. The impacts were documented through multiple formats of assessments multiple times, self-assessment ratings of confidence levels and feedback on multiple parameters upon completion of the program. The results indicate TBL's efficacy in enhancing participants' learning of solar rooftop technologies, with several exposures to technical proficiencies through tasks, and promotion of collaboration in team based learning environments. This study provides insights for educators facing comparable multilingual and technical challenges a methodology which could improve learning effectiveness especially in industry specific training areas. The study includes discussions on the challenges due to language and equipment related barriers, and the actions required to overcome these barriers. The study concludes with recommendations of how this can be extended to various other contexts of capacity building in solar photovoltaics.
