As a growing number of faculty use constructivist and constructionist approaches to teaching in SL, little research exists on the many ethical considerations and legal implications that affect course development. Following the experiences of the instructor and five students, their 12-week journey is documented through interviews, journals, blogs, weekly course activities, SL class dialogs, and ...

By fluorescence enhancement of a proximity-dependent DNA-scaffolded silver nanocluster probe pair and exonuclease III-mediated signal amplification, we present a new fluorescence turn-on mode and its application for specific DNA detection.

Educational applications (apps) are ubiquitous within children's learning environments and emerging evidence has demonstrated their efficacy. However, it remains unclear what the active ingredients (ie, mechanisms), or combination of ingredients, successful maths apps are. The current study developed a new, open-access, three-step framework for assessing educational value apps, comprised type a...

While the effect of scaffolding on learning has received much attention, less is known about its effect on students’ strategy use, especially in transfer activities. This study focuses on students’ adaptive behaviours as a function of given scaffolding and when transitioning from a scaffolded to an unstructured activity. We study this in the context of a complex physics simulation in which stud...

Support from the Henry Luce Foundation allowed a team of Centre College faculty to develop multiple integrated programs connecting study Asia environment: Summer Language Institute (CSLI), & Environment Lab (A&E Lab), January term courses abroad, student summer research and internships dissemination research. Each these high-impact practices (HIPs) alone has been empirically demonstrated enrich...

The learning of writing is complex because it requires the development cognitive and linguistic abilities. Effective teaching demand guided practice. South African National Curriculum Statement Grades R–12 includes Assessment Policy (CAPS) for First Additional Language (FAL) learning. It introduces use question-prompt frames to learn in grade 4. In second part 5 year, process introduced as a fr...

The aggregation of cells by lectins or antibodies is important for biotechnological and therapeutic applications. One strategy to augment the avidity and aggregating properties of these mediators is to maximize the number of their ligand binding sites. The valency of lectins and antibodies, however, is limited by their quaternary structures. To overcome this limitation, we explored the use of p...
