Under the general teaching environment, to achieve the interaction between students and teachers relies on materials-teach and question –asking in class. As the Internet grows up, students don’t have to consider when or where they communicate with others, just by the learning web site. But the interaction between students and teachers is limited to active exploring by students.
With the help of short message, teachers don’t need to communication with students just by waiting them asking questions actively. Teachers could actively push learning-messages to those students who need by our mobile learning aided system. Students could receive learning-messages even in passive status.
After we get the function of short message, we have some problems about when to send and what to send is suitable. Our system gets the sending rules from the association rules trained by detecting what content they like and when to send they prefer. Besides some unexpected situation that the interval from the message we sent to the acknowledge students response we couldn’t accurately predict, we have about 70 percent accurate rate on predicting when to send, what content they like, and the level of nervous before/after they receive messages.
According to Lewin’s nervous system, it’s positive for someone on recall, memorization, or goal-approach by keeping one’s nervous status. Thus, we want to realize the relation between nervous status and other learning related attributes to improve learning performance. By getting students’ nervous level from affective detection module, we could change the message to become threatened or pressed while the students’ nervous level is below the threshold.
Though we didn’t find the factor affecting the changes on nervous, we found that the lowest-degree students’ nervous level grows up before the course test or the deadline of the homework according to observing the data. And we found 67 percent of the students who think that the message would make an effect on their nervous level, 74 percent of the students who would deal with the message if it levels up their nervous status, and 76 percent of the students who would deal with the message in 3 hours. |
