We have proposed a method to model user's shifting interest from browsing history. We call the filtering method Context-Sensitive Filtering, CSF for short. This paper describes an application of CSF to Web, that is, Web FALCON that divides a Web...

A framework for designing intelligient assistance in discovery learning environment is proposed. The process of discovery learning is analyzed and the required functions for intelligient assistance are discussed. A flexible simulator which fits...

In this paper, a problem-authoring method is proposed and an example of the implementation of the method is described. In the problem-authoring method, a new problem is characterized using differences from the basic problem. In the problem-authoring ...

This paper presents a method of judging answers to a question in the question and answer function in an intelligent CALL system for English learning. Both the questions and answers are English sentences. First, expected correct answers are generated ...

In this paper, we propose a general framework of the learning environment in which the system can explicitly assist a learner's scientific activity. A learner can improve her hypothesis and model of the domain developmentally with the guidance of...

We are investigating a method to visualize errors to help a student to learn from the errors. The target domain of this paper is multi-digit subtraction. We, first, introduce the block-box model where the minuend is embodied as blocks and the...

This paper proposes a method of learning assistance for a physics learning environment. The learning objective of the environment is to acquire ability of recognizing forces acting on physical objects. Because the knowledge of applying fundamental ...

In this paper, a learning environment that supports a learner to design physics experiments is described. In the design process, the learner is required to derive a physical attribute value in a concrete situation by measuring several attribute...

We have designed and developed an interactive learning environment for problem-posing in arithmetic word problems that are solved by one operation of either addition or subtraction, “MonsakunII”. In this study, we report a practice of arithmetic...
