The main purpose of this study is to construct a learning system with a pedagogical agent to assist grade 6 elementary school students to learn mathematics. In order to make up for the shortage of feedback in traditional on-line learning systems, this system manipulates a pedagogical agent mechanism to raise student motivations and give them prompt feedback to support and improve their mathematics learning. Concerning the purpose of understanding this systems various effects for different level

... students (high, average, and low), this study uses an experimental approach with 62 students as the sample and conducts t-test for statistical processing among levels. In addition, the researchers interviewed participants for greater understanding of the learning effects utilizing this system. The study found that the pedagogical agent has a valuable, positive, and efficient effect on students mathematics learning no matter if their mathematics levels are high, average, or low.
