Novice Learner Experiences in Software Development: A Study of Freshman Undergraduates

This paper presents a study that is part of a larger research project aimed at addressing the gap in the provision of educational software development processes for freshman, novice undergraduate learners, to improve proficiency levels. With the aim of understanding how such learners problem solve in software development in the absence of a formal process, this case study examines the experiences and depth of learning acquired by a sample set of novice undergraduates. A novel adaption of the Kirkpatrick framework known as AKM-SOLO is used to frame the evaluation. The study finds that without the scaffolding of an appropriate structured development process tailored to novices, students are in danger of failing to engage with the problem solving skills necessary for software development, particularly the skill of designing solutions prior to coding. It also finds that this lack of engagement directly impacts their affective state on the course and continues to negatively impact their proficiency and affective state in the second year of their studies leading to just under half of students surveyed being unsure if they wish to pursue a career in software development when they graduate

Some interfaces in conventional and distance education programmes in a postmodern context

This article emanates from a comparative study of the quality of a B.Ed. (Hons) programme in contact and distance contexts in a dual-mode institution, in terms of access, delivery and output. Both versions of the programme are guided by a similar underpinning philosophy that drives its ethos. Even though it appears that there may be no prominent discrepancies between the two modes of training delivery, institutions that decide to venture into rural areas are faced with challenges that have to be sorted out if the quality of a given distance education programme is to be enhanced. Also, there is the need for institutions to distinguish between academe that are interested in distance education and those that are not in order to improve on their research status. Finally, suggestions are proffered on how institutions in an African setting can improve the quality of their programmes. South African Journal of Higher Education Vol. 22 (3) 2008: pp. 484-49

Genetic and molecular bases of yield-associated traits: a translational biology approach between rice and wheat

Transferring the knowledge bases between related species may assist in enlarging the yield potential of crop plants. Being cereals, rice and wheat share a high level of gene conservation; however, they differ at metabolic levels as a part of the environmental adaptation resulting in different yield capacities. This review focuses on the current understanding of genetic and molecular regulation of yield-associated traits in both crop species, highlights the similarities and differences and presents the putative knowledge gaps. We focus on the traits associated with phenology, photosynthesis, and assimilate partitioning and lodging resistance; the most important drivers of yield potential. Currently, there are large knowledge gaps in the genetic and molecular control of such major biological processes that can be filled in a translational biology approach in transferring genomics and genetics informations between rice and wheat
