Adding and subtracting complex numbers
This animation shows how to add or subtract complex numbers, using a simple example
Referencing Websites
An interactive tutorial on how to reference websites. It begins with an example, and interactively draws the student through the stages of accessing the relevant information.
Manipulating Logs - Practice Test
A ten question test on manipulating logs (by addition, subtraction, multiplication, division
Acid/Base Equilibria
A number of examples of mathematical treatment of strong and weak monoprotic acids and bases, as well as buffers. The site presents a brief conceptual introduction to each case and then treats mathematically the steps to solve an example problem related to the concept.
Chemical Equilibria: The Law of Mass Action
Fundamental ideas and terminology of equilibria from a general chemistry perspective. A focus on closed systems, reversible chemical reactions, the law of mass action, Q and K. Also included are several multiple-choice questions that test the theories discussed. This site provides supplementary material that could be useful to beginning students in general and analytical chemistry.
Paper Chromatography of Stains
A paper chromatography experiment separating dyes. The experiment is targeted toward 8-12 grades, but could be suited to an introductory chem laboratory section.The text of the site contains instructions for setting up and executing the experiment in a large class setting.
Paper Chromatography
A site with animation that provides a very brief introduction to the idea of separation of components in a mixture and a set of instructions for students for separating colored compounds by paper chromatography (on coffee filters). The appropriate audience would be students in a high-school or introductory, non major\'s college chemistry class.
How People Learn: Brain, Mind, Experience, and School: Expanded Edition (2000)
This page, in the National Academy Press website, gives the table of content of the book in the title of this site. As one of the "openbooks" from this press, the site allows one to search the book (approximately 400 pages) as well as download the complete book or selected portions of it. The site will be most useful to an analytical scientist interested in reading about current learning theories.
The Web: Design for Active Learning
This page focuses on interactivity as it applies to a cohesive design including, high interface, content, and instructional design. This page is usable in gathering strategies for applying active learning in a college environment, although none are specifically related to analytical chemistry. Unfortunately, several of the links on the page are broken, but there are a number of useful ones.
Student Assessment of Learning Gains
This University of Wisconsin site is designed for instructors of all disciplines who would like feedback from their students about how the course elements are helping their students to learn. This page is a usable link for assessment, collaborative learning and technology in all college science courses by faculty or graduate students, although there is no particular focus on analytical science.
The History of Mass Spectrometry
This site provides a brief history of the development of mass spectrometry. The works of Thompson and Aston are presented along with a brief overview of the modern evolution of mass spectrometry. This site will be useful for beginning students interested in a historical overview of the field of mass spectrometry. This is an archived version of the site.
Introduction to Mass Spectrometry
This site contains an on-line text on mass spectrometry at the intermediate level. The text gives good general coverage of mass spectrometry instrumentation and applications in very readable format. It contains nice diagrams that provide a visualization of the ionization and mass selection processes. It also contains an overview of applications of mass spectrometry near the end that is different than most sites related to MS. It is especially appropriate for intermediate students.
Rheodyne - Application Support
Application notes, technical information, and on-line trouble-shooting guide pertinent for Rheodyne products (high-pressure valves).
L'image de l'Amérique au début de la colonisation : débat
Jean Paul Duviols tente de déterminer l'origine authentique du nom des trois caravelles de l'expédition vers le Nouveau Monde. Par la suite, ce sera sur la considération positive du rôle de Christophe Colomb parmi les conquistadors alors qu'en réalité c'est lui qui a initié ce profond mouvement de colonisation.
Statistical Tools: Binomial Confidence Interval
This page calculates the confidence interval for a binomial probability.
Confronting Some Statistical Inference Misconceptions
This lesson poses a series of questions designed to challenge students' possible misconceptions of statistical inference and hypothesis testing. The lesson uses the statistical software, Fathom, and three datasets with information on the number of chips per canister distributed by a snack maker. The data can found at the relation address below.
SITE INVESTIGATION
"Site Investigation" by C.R.I. Clayton, M.C. Matthews and N.E. Simons
Saddling the whirlwind: exploring an organizational culture of a hybrid library
How to cope with the whirlwind of changes with no additional staff or money? The small cataloging unit seeks the answer on this familiar question in its organizational culture that includes a “team” and “hierarchical” components. Both cultures are considering as the internal resource which can be directed to fulfill the growing demands for services from cataloging clients. The presentation clarifies the roles of “team” and “hierarchical” cultures in the process the initiation, d
