A Dynamic Communication of Companion Agents based on Learning Strategies of Students

KASAI Toshinobu, OKAMOTO Toshio

IEICE technical report. Education technology 99 ( 81 ) 73 - 80 1999.5

Language：Japanese Publisher：The Institute of Electronics, Information and Communication Engineers

Among the learning effects which are expected by collaborative learning, in this study we concentrate on problem-solving knowledge fixing with 'Learning by Teaching' and problem-solving knowledge acquisition with 'Learning by Observing'. We propose a virtual collaborative learning environment, called CASLE (Companion AgentS Learning Environment), embedding Companion Agents which have each of these learning effects as Teaching Strategies. These Companion Agents' behavior is based on a 'Student Model', which represents the understanding states of a Real Student, and a 'Learning Strategy Model', which represents what level of knowledge a real student acquires by experiencing a situation in the collaborative learning environment, according to each Teaching Strategy. A Facilitator Agent manages these Models and controls the Companion Agents' behavior. Moreover, it identifies faults of learning strategies of the real student from the Learning Strategy Model, and it points them out to him.

The case amendment structure based on a learning activity model in the information education practice case reasoning system

KANEDA Katsuhiko, TAKAOKA Ryo, KASAI Toshinobu, MATSUI Tatsunori, OKAMOTO Toshio

IEICE technical report. Education technology 99 ( 31 ) 15 - 22 1999.4

Language：Japanese Publisher：The Institute of Electronics, Information and Communication Engineers

In this study, we develop the information education practice case reasoning system which provides information of the practice case to a teacher who is engaged in information education. As to provide the practice case, we need to build DB with indexing practice cases. And we need to design a function which reasons a practice case which a user demands from DB. Moreover, not only function which provides the practice case simply, but also amends the reasoned case according to user's demands are necessary. So, in this study we apply Case-Based Reasoning in a system. And the system amends learning activity according to user's demands, making use of an case amendment function which is one of Case-Based-Reasoning's functions. We propose a method which amends learning activity according to relations among each activity and instructional goals. In this paper, we describe about compositions of the information education practice case reasoning system and the amendment function in detail.

The Basic Concept of Supporting Collaborative Learning embedding Peer Agents

KASAI Toshinobu, OKAMOTO Toshio

IEICE technical report. Education technology 98 ( 76 ) 17 - 24 1998.5

Language：Japanese Publisher：The Institute of Electronics, Information and Communication Engineers

There are two kinds of learning effects expected of providing a learners a Cooperative Learning Environment. One is a fixing of problem-solving knowledge by way of reflection which is facilitated by explaining to peer students(Learning by Teaching). The other is an aquisition of problem-solving knowledge by way of observing peer student's behavior(Learning by Observing). We propose an Intelligent Cooperative Learning Environment the purpose of which is an enhancement of these learning effects by embedded Taught Agent and Observed Agent called Peer Agent. Taught Agent's aim is to facilitate a real student's Learning by Teaching, and Observed Agent's aim is to facilitate his/her Learning by Observing. These agents'behavior are controlled by Facilitator Agent. Facilitator Agent adopts more effective strategy according to a real student's state about problem-solving knowledge and cognition of peer student's state. Moreover, he amends adopted strategy to enhance real student's cognitive ability about peer student's state, and instructs a Peer Agent to behave with on amended action.

IEICE technical report. Education technology 97 ( 82 ) 33 - 40 1997.5

Language：Japanese Publisher：The Institute of Electronics, Information and Communication Engineers

The purpose of this study is to construct a peer learning environment within the framework of a multi-agent system. Expected result is that by installing the Computer Companion (as one of the agents), a real student will be able to get a deep understanding of his own ability of problem-solving through ovservation and reflection. For such a learning process, the ability of recognizing the state of peer students accurately is required, as a student learns behavior which he judges to be necessary for himself from the state of peer students, recognized through his actions in a peer learning environment. If a student lacks the ability, he learns a wrong behavior and at the same time regards a correct behavior of a peer student as an error. For these reasons, we have developed an agent based mechanism for enhancing meta-cognition (i. e. monitoring the state of peer students and also monitoring the process of recognition) in this research.

The purpose of this study is to construct a peer learning environment in a frame of multi-agent system. Expected results are; with installing Computer Companion(as one of agents), a real student will be able to get deep understanding of his own ability for problem-solving through observation and reflection. For such a learning process, the ability for recognizing the state of peer students accurately is required. For supporting an enhancement of ability of meta-cognition intelligently, it is required to build a model. Then, the main purpose is to build a peer student's understanding model. Based on this model, the system evaluates a real student's ability of meta-cognition and supports an enhancement of ability of meta-cognition intelligently.
