Metacognition in Solving Process of Basic Electric Circuit ProblemmComparison of Metacognitive Characteristics between Non-major and Major Students in Electric Engineering

There are learners who cannot solve practical problems in spite of mastering basic scientific knowledge and formula necessary for the solution. One of the reasons might be attributed to the lack in metacognitive abilities. The aim of this study was to compare the metacognitive characteristics between non-major and major students in electric engineering and clarify the difference of metacognitive process between these two groups when solving basic problems of electronic circuit. In the experiment, the solving process was compared between non-major and major students in electric engineering using five basic problems. We found that the scores on prediction of result and confidence of own answer differed significantly between non-major and major students, and inferred that the difference of performance was due to the lack in metacognitive ability, especially the plan and the execution abilities. Both prediction of results and confidence of own answer were also found to play a significant role in effective problem solving as important components （subsystems） of metacognition.

Cooperative Understanding of Utterances and Gestures in a Dialogue-Based Problem Solving System

A dialogue plays an important role in learning how to solve a problem and form a concept. We are developing a problem solving and knowledge acquisition system based on co-reference between drill texts and dialogue with a teacher, focusing on first-grade mathematics. This paper presents a method of cooperative understanding of utterances and gestures within dialogue. We first describe our system design principles, which provide the basis for the integration of multimodal information during a dialogue. We define a principle of complementarity, explain its implementation, and describe the architecture of the problem solving system. We then show how to integrate our algorithms for utterance and gesture analysis within that software architecture. A feature-based approach is used for gesture recognition, derived from a sequence of images arising during the cooperative analysis of utterances. We conclude with an evaluation of the system against the design principles.

Online Government Services： The Benefits for Operations of Small and Medium-Sized Businesses in Quebec

Online government services enable businesses to broaden their operations and increase their productivity, ha most businesses, there is a strong demand for the delivery of e-government services because such services indeed provide better service delivery, healthier relationships with government authorities, less loss of time and fewer logistical limitations. The competitive advantage generated by these services is linked to recently developed products, know-how and ability to meet customer needs. The purpose of this paper is to analyze the role of online government services in the development of SMBs （small and medium-sized businesses） in the context of the strong growth in online services that government bodies and institutions have made available to businesses. Using different electronic tools as online forms, businesses can use the information available and consequently generate gains in productivity and competitiveness （lower transaction costs, less time and less effort）. Specifically, this paper examines the extent to which the use of online government services affects SMB operations and the role of these services in the evolution of SMBs toward new business models.

Dynamic consensus of high-order multi-agent systems and its application in the motion control of multiple mobile robots

In this paper, the leader-following consensus problem for multi-agent linear dynamic systems is considered. All agents and leader have identical multi-input multi-output (MIMO) linear dynamics that can be of any order, and only the output information of each agent is delivered throughout the communication network. When the interaction topology is fixed, the leader-following consensus is attained by H∞ dynamic output feedback control, and the sufficient condition of robust controllers is equal to the solvability of linear matrix inequality (LMI). The whole analysis is based on spectral decomposition and an equivalent decoupled structure achieved, and the stability of the system is proved. Finally, we extended the theoretical results to the case that the interaction topology is switching. The simulation results for multiple mobile robots show the effectiveness of the devised methods.
