Summary and Conclusions
In this study, I developed Internet based educational software for acid-base titration experiment.  This program consists of the information and experiment parts.  The information part was designed to help understand the concepts of acid-base and titration and the experiment part simulates the titration process. 

Three undergraduates and one graduate student participated in the evaluation of the program.  The subjects agreed that the software helped understand the concepts and they liked several feature of the program: the connection of science concepts to real life, easy and step by step explanation, visual display of the content, opportunity to design their own experiments, and realistic response of the program such as color and volume changes of the solution.  However, there were some problems that have to be fixed: small display size and separated information from the simulation program.

Although there are some criticisms about lab simulation programs that computerized experiments lowered the quality of teaching laboratories (Markow & Lonning, 1998), the program helped the students understand the principles and procedures of acid-base titration and experience various experiments without much effort.  I hope that this program can help more students understand the acid-base titration and get some message from the users about their successful applications of the program soon.
