| Summary: | Nowadays most of the students are having difficulty when it comes to Chemistry. Students tend to commit errors and come up with wrong solutions not because they failed to understand the topic, but they are still having problems with the basic concepts of Stoichiometry. Stoichiometry deals with the quantitative study of reactants and products in a chemical reaction. The system will track the student's progress in terms of their knowledge in all of the topics under Stoichiometry as it builds the foundation of the student in Chemistry. Intelligent Tutoring System are software programs that support learning activity as it offers the advantage of individualized instruction without the expense of one-to-one human tutoring (Gamboa, 2001). The system's target is to give and generate problems related to Stoichiometry. In every problem the system should be ready to explain and aid the user to clarify misconceptions on concepts and solving problems. It is also important to present the system in an adaptive way by giving analogical explanations which will be used to make the topics in Stoichiometry understandable as it will be an alternate approach in discussing difficult topics. It is also the job of the system to monitor the progress of the users since it focuses on the student's progress. Bayesian Network is also used to generate the belief value in terms of the user's performance as this will suggest appropriate topics that suit their current performance. This research aims to develop a system that will boost the system's target users: high school and college students to love and understand fully the concepts behind Stoichiometry as to build the foundation in Chemistry and at the same time to help the youth in an educational aspect. |
