Visualizing Numerical Methods (2) William F. Coleman These movies are designed to help students visualize various numerical approaches to evaluating functions or solving equations. The methods themselves may be familiar to students from their mathematics courses, but they may have forgotten the material or never made the connection between a statement such as "the derivative of a curve at a given point is the slope of the line tangent to the curve at that point" and the way that one might evaluate such a derivative. All of the movies have VCRstyle controls that enable the student to step through them one frame at a time and to move backwards as well as forwards.

A Method of Visual Interactive Regression Michelle S. Kim, Maureen Burkart, MyungHoon Kim Over the past decade many colleges and universities have placed increased emphasis on having students develop statistical and data analysis skills in a range of disciplines. Some institutions now require that all students complete at least one course with a strong component of data analysis, whether the data are from chemical experiments, the census, or some other source. As chemists, one of our concerns should be to ensure that students view data analysis as an integral part of any quantitative experiment, and, as far as possible, do not treat this process as a black box. The authors of A Method of Visual Interactive Regression, a spreadsheet application, have developed a visual approach to linear leastsquares curve fitting that drives home the idea of minimizing the sum of the squares of the deviations in order to find the best fit to a set of data that are being described by a linear relationship. For many students these visualizations are likely to persist a great deal longer than the mathematical derivations of the equation for the slope and the intercept. The visualizations will provide a useful connection between a set of equations and the buttons on a calculator or the insertion of a trendline in a spreadsheet.

Kinetica; An Excel program to Stimulate or Analyze Kinetic Data Leonel Vera, Pedro Ortega, Miguel Guzmán The Excel spreadsheet Kinetica both simulates and analyzes kinetic data for simple rate equations of the form:  d[A]/dt = k [A]^n Instructors or students can generate simulated kinetic data using parameters they specify, or using parameters randomized by Kinetica. The data set that is generated may then be exported for use in exercises, homework, and exams, or may be analyzed directly within Kinetica. A kinetics data set may also be imported from an external source into Kinetica for analysis.

An Excel Program to Study FirstOrder Kinetics Ken Muranaka User data can be analyzed to determine what parameter values of the first order rate expression give the closest fit, or data can be generated using userinput values of the rate parameters and random noise levels. Statistical characterizations such as confidence limits and variance are calculated.

MechanismBased Kinetics Simulator Robert M. Hanson Simulate the kinetics of a reaction based on its mechanism using JavaScript. The idea is to write a mechanism and, based on that, follow the course of concentrations or rates of change in concentration of reactants, catalysts, intermediates, and products over time.

Some Unusual Applications of the "Errorbar" Feature in Excel Spreadsheets Kieran F. Lim Novel uses of the "errorbar" feature of spreadsheet packages in the areas of enzyme kinetics, vibrational spectroscopy, vibronic spectroscopy, and mass spectrometry are discussed. It is argued that using software features for purposes that were not envisioned by the programmers fosters flexibility and innovation.

Equilibrium Matthew Sandberg, Mike Bellamy Using a visual approach, this applet is designed to help students learn to solve equilibrium calculations and also to help them gain a deeper understanding of the topic. It can be used by the instructor in the classroom as equilibrium topics are introduced. Sample exercises for students are included. The text is available in both English and Spanish.

JavaScript Programs To Calculate Thermodynamic Properties Using Cubic Equations of State Patrick J. Barrie Cubic equations of state are widely used by chemists and chemical engineers to predict the thermodynamic properties of both pure substances and mixtures. In particular, these equations enable predictions concerning the temperature and pressure at which vapor liquid equilibrium occurs. These two educational JavaScript programs perform calculations using cubic equations of state and, equally importantly, explain how the calculations are performed.

Connected Chemistry Mike Stieff Connected Chemistry, a novel learning environment for teaching chemistry, is appropriate for use in both high school and undergraduate chemistry classrooms. Connected Chemistry comprises several molecular simulations designed to enable instructors to teach chemistry using the perspective of emergent phenomena. That is, it allows students to see observed macrolevel chemical phenomena, like many other scientific phenomena, as resultant from the interactions of many individual agents on a microlevel. This perspective is especially appropriate to the study of chemistry where the interactions between multitudes of molecules on the atomic level give rise to the macrolevel concepts that students study in the classroom. Connected Chemistry comprises molecular simulations embedded in the NetLogo modeling software (1). The collection contains several predesigned simulations of closed chemical systems to teach specific chemistry concepts. Currently, Connected Chemistry contains models for teaching Brønsted Lowry acid base theory, enzyme kinetics, radical polymerization, buffer chemistry, kinetics, chemical equilibrium, and crystallization. Instructors and students can individually tailor the predesigned simulations or generate new simulations as they are needed in the context of a particular lesson, classroom, or department.
