The Influence And Its Mechanism Of Computer Feedback To Internet Learning

With the rapid development of Internet and network technology,the network has become an important channel for people to obtain knowledge and information.Network learning has occupied a space in education,which is not only an important supplement to the current education system,but also is an effective way for people's lifelong learning.Network learning Web based learning refers to the student obtains information by means of the Internet,which is a new way of learning via the interaction between the teachers,peers and the network environment.Network learning brings convenience for learners and teachers,which has become an important part of human learning.There are many factors that influence the effect of network learning.Feedback is one of the important factors to obtain knowledge and skills in network learning.Feedback can help learners to correct errors in timely,promote the human-computer interaction,stimulate students' motivation and interest in learning and also promote the learning effect.The traditional learning feedback is often provided by teachers in oral or written way.With the progress of modern technology,the network feedback can also be provided by the computer program,which called computer-based feedback,referred to as computer feedback.At present,there is no consistent research conclusion on the computer feedback of different types,while the previous research on the feedback of college students' network learning is lack,so it is necessary to conduct a systematic study on computer feedback.This research designed the computer feedback learning program based on network,with the blood circulation of the human body of scientific knowledge as the theme,which tested the college students by a series of experiments to explore the effect of the different feedback,and to reveal the mechanism of the feedback in network learning.The main conclusions are as follows:1.Compared with no feedback,the feedback has better learning effect,which can effectively promote the learner's motivation,and has a positive effect on the following study;Compared with the total feedback,item by item feedback is conducive to enhance the learning motivation.2.In the case of item by item feedback,the interaction between the feedback's complexity and the affective encourage is significant on the learning motivation and the following learning score.In the no emotional encouragement condition,the elaboration feedback is more conductive to enhance learners' learning motivation and subsequent learning achievement;while in the emotional encouragement condition,there is no significance in the simple feedback and the elaboration feedback.3.In the case of total feedback,simple feedback is as effective as complex feedback,and affective feedback has no significant influence on the learning effect.4.The interaction between the media and the agent is significant on the learning motivation,which are some differences between the simple feedback and the complex feedback circumstance.In simple feedback condition,adding sound elements in no agent environment has nothing effect on students' learning motivation,while adding sound elements in the agent environment can effectively improve the students' learning motivation;In elaboration feedback condition,adding sound elements in no agent environment can enhance students' learning motivation,and adding sound elements in the agent environment is of no avail to motivation.5.The influence of media and agency factors on the subsequent academic achievement is basically the same between simple and elaboration feedback conditions.The interaction between the media and the agent is not significant;the main effect of the media is significant,adding sound can promote the subsequent academic achievement;the main effect of the agent is not significant.6.Learning motivation has different roles in different task types:in the detail memory task,learning motivation has a full mediation effect between feedback and subsequent learning achievement;but in the comprehensive reasoning task,learning motivation has no mediation effect between feedback and subsequent learning achievement.7.Prior knowledge has a moderating effect on feedback effects:in the details of the memory task,prior knowledge by adjusting the learning motivation effect on the details of the memory result,indirect regulation of feedback complexity on the details of memory performance,and the moderating effect of complete intermediary.In the comprehensive reasoning task,prior knowledge only directly regulate the feedback relationship between complexity and reasoning the moderating effect of performance,not through the intermediary role,intermediary regulation model is established.
