Multiple conceptualizations of the interrelation between assessment and learning yield three notions of assessment: assessment of learning, assessment for learning, and assessment as learning. This paper aims at uncovering roles and obstacles of assessment for learning and assessment as learning in English language classrooms in Hong Kong. Grounded upon the theory of constructivism and the noti...

A BSTRACT Artificial Neural Network (ANN) algorithms provide powerful techniques for the construction of computing systems which are capable of adapting to non-stationary or incompletely specified operating environments. Unsupervised learning is of particular interest in such situations. This paper reports the results of empirical studies into the characteristics of standard and soft competitiv...

Peer assessment appeared in social constructionism theory since peer activity involves the joint construction of knowledge through discourse. This study focuses on one product that arises from peer-assessment activity: feedback peers. Besides, this linked and learners' autonomy language learning. Autonomous learning is regarded as a desirable goal an educational context. In exploring issue, use...

This paper describes the main activities and achievements of our research group on Machine Intelligence and Robotics (Grima) at the Computer Science Department, Pontificia Universidad Catolica de Chile (PUC). Since 2002, we have been developing an active research in the area of indoor autonomous social robots. Our main focus has been the cognitive side of Robotics, where we have developed algor...

We propose Behavior Engineering as a new technological area whose aim is to provide methodologies and tools for developing autonomous robots. Building robots is a very complex engineering enterprise that requires the exact definition and scheduling of the activities which a designer, or a team of designers, should follow. Behavior Engineering is, within the autonomous robotics realm, the equiva...
