The need for shifting the expository laboratory instruction style to inquiry-based approaches is widely acknowledged. Problem-based learning (PBL), one of the inquiry-based approaches, advocates students’ self-directed learning. The literature...
1,3,5-triaryl-2-pyrazoline derivatives were synthesised by a condensation reaction between chalcones and phenyl hydrazine using cerium chloride heptahydrate as a catalyst. All these reactions were carried out in ethyl lactate (70%) as a green solvent. Easy and efficient work up, recyclability of solvent and catalyst are the key merits of this protocol.
Undergraduate students tend to find organic chemistry rather challenging and we as teachers of the subject are constantly trying to find new ways to enthuse students and help them understand and enjoy the subject. Active learning has taken centre stage today and one such student-centric teaching strategy, process-oriented guided inquiry learning has been explored by us. In this article we present our experience, the advantages of this teaching methodology and the likely challenges in implementation.
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.
