Children's academic performance and social competence in school is positively associated with parent involvement. However, the researches about educational learning models often ignore the parent part. Moreover, Internet forms a new paradigm, education and communication approach is more complicated than ever. In this paper, we would like to introduce an Education Wheel model (EWM) which includes students, teachers and parents in the education environment. Under EWM framework, we design an E-Homebook System (EHS) with agents which provide a teacher-parent-student communication interface through Internet. The EHS comprises intelligent agents: interaction agent, instruction agent, information agent, evaluation agent and log agent. The agents manage a learning portfolio conception, observe and record students' e-learning behavior through the web log, and provide teachers a reference of portfolio information. The agents adopt a trigger function to analyze the students' learning behavior from Internet as well as from classroom, evaluate overall performance, then send an e-mail message automatically to the teachers and parents to guide and assist the students who need to revise their learning attitude. Similarly, the agents will record parents' participation portfolio, then teachers may draft better communication strategy. The EHS provides a better communication role between students-parents-teachers, implements an integrated performance measurement method, and conducts a better teaching strategy support interface for elementary education.
