Creating Meaningful Learning Opportunities through Incorporating Local Research into Chemistry Classroom Activities

Nicole States et al.

Summary: Incorporating real-life context through research connections in early curriculum promotes meaningful learning and deep engagement with chemistry knowledge. This study created four activities in an introductory chemistry class to integrate authentic research connections, and included metacognitive questions to help students connect prior knowledge with course content. The tasks were analyzed using Marzano's taxonomy, with increased cognitive complexity in the revised activities to allow for more knowledge construction opportunities. Qualitative analysis of student engagement revealed the need for proper facilitation by trained instructors to promote conscious engagement in meaningful learning.

A critical review of experimental and CFD techniques to characterize the mixing performance of anaerobic digesters for biogas production

Lili Li et al.

Summary: Biogas from anaerobic digestion is an important alternative to fossil fuels, contributing to energy recovery and environmental sustainability. Mixing plays a critical role in biogas production, with intermittent mixing preferred for maximum biogas production. Local experimental techniques are simple and cost-effective for arbitrarily sized digesters, while global experimental techniques relying on computer systems are gaining attention for their applications in anaerobic digestion flow fields. Further research is needed to develop new experimental techniques that overcome the limitations of digestate opacity and industrial reactor geometries, and compartmental models based on computational fluid dynamics show promise for greater implementation of CFD applications.
