The plant taxonomy textbooks that are generally used in colleges need to be complemented with a DNA-based molecular review. In general, plant taxonomy textbooks devote more space to morphology than to molecular-level characteristics. The research reported here used the results of DNA-based research to develop a molecular plant taxonomy textbook.…

In the 2 day lesson presented in this article, students explain how ionic substances interact in solutions by developing and revising their own explanatory models. The lesson engaged students in three-dimensional learning through creating and revising their own models to explain the interaction of ionic substances and polar molecules in a closed…

Stimulus-secretion coupling (SSC) in endocrine cells remains underappreciated as a subject for the study/teaching of general physiology. In the present article, we review key new electrophysiological, electrochemical, and fluorescence optical techniques for the study of exocytosis in single cells that have made this a fertile area for recent…

The purpose of this exploratory study was to identify and describe some of the dimensions of scientific collaborations using high throughput computing (HTC) through the lens of a virtual team performance framework. A secondary purpose was to assess the viability of using a virtual team performance framework to study scientific collaborations using…

This paper reports the results of applying a particular analytical perspective to data from an interview study: a typology of learning impediments informed by research into learning and students' ideas in science. This typology is a heuristic tool that may help diagnose the origins of students' learning difficulties. Here it is applied to data…
