Daunting Task

Searching for reaction in organic synthesis has been made much easier in the current age of computer databases. However, the dilemma now is which procedure one selects among the ocean of choices. Especially for novices in the laboratory, it becomes a daunting task to decide what reaction conditions to experiment with first in order to have the best chance of success. This collection intends to serve as an "older and wiser lab-mate" one could have by compiling many of the most commonly used experimental procedures in organic synthesis. With chapters that cover such topics as functional group manipulations, oxidation, reduction, and carbon-carbon bond formation, Modern Organic Synthesis in the Laboratory will be useful for both graduate students and professors in organic chemistry and medicinal chemists in the pharmaceutical and agrochemical industries.

Basil Lythgoe was distinguished as an organic chemist. He began his career at the University of Manchester, where he had studied for his undergraduate and PhD degrees, before moving to University of Cambridge. During this period he collaborated with Alexander Todd on the structural elucidation and total synthesis of the natural nucleosides, and was also noted for his investigation of the structure of the natural substance macrozamin. In 1953 he moved to the chair of organic chemistry at the University of Leeds, running a research group from which several graduate students went on to academic careers of the highest distinction. At Leeds he worked on the structure of the alkaloid taxine 1 and calciferol, among other natural substances. Lythgoe's work was characterized by a combination of insight and high experimental skill.

Before And After

Abstract Elicited student mental models reveal students’ understanding of a given system as well as their ability to communicate knowledge of that system to others. Understanding how students form and developmental models of systems is critical to the progress of engineering education. In this work, graduate students’ mental models of common household products are measured before and after instruction on functional modeling and functional decomposition. These mental models are measured using previously published, but still developing mental model instruments. The included systems are a hair dryer, clothes dryer, and vacuum cleaner with accompanying scoring rubrics. Results show statistically significant improvements on average mental model rubric scores on all three given systems after the functional modeling intervention. These results suggest that curriculum content on functional modeling and decomposition likely improves students’ mental models of engineering systems and their ability to communicate their knowledge about those systems. As we improve our understanding of how students form, change, and communicate their mental models of engineering systems, educators can shape curriculum to facilitate the skills necessary for comprehensive systems understanding.
