In the resolution of problems in chemical kinetics and catalysis the mathematical models relate the independent variable that is usually time, with the dependent variable which is normally the concentration of a reactant. They conform to linear models, whose parameters such as the ordering to origin and the slope are kinetic parameters, applying…

Kelly, Janet; Bradley, Curtis; Gratch, Jonathan – Online Submission, 2008
The purpose of this study was to compare and contrast laboratory simulations with traditional (equipment) explorations in physics to determine differences, if any, in student achievement and changes in attitude toward science. Based upon the investigations conducted in undergraduate physics classes with 96 students who were non-science majors, it…

Using the System Schema Representational Tool to Promote Student Understanding of Newton's Third Law
Hinrichs, Brant E. – Online Submission, 2004
The purpose of this study was to examine the effect on student understanding of Newton's Third Law in an introductory calculus-based physics class when a new graphical representational tool called a system schema was used throughout instruction to help visualize objects and interactions between them explicitly. The system schema serves as an…

Yavuz, Soner – Online Submission, 2007
All events in the world are caused by chemical events and reactions. One of the most important aims of life chemistry is bringing up individuals who have sensitivity towards the environment and environmental awareness; could apply their learnt knowledge to daily issues and problems; have the ability to comment and adopt their knowledge into…
