This paper will describe current work at Alelo to track learner interactions with learning systems and analyze the data to derive profiles of learner competencies. This includes both linguistic knowledge (e.g., the ability to recognize and recall words and phrases) and linguistic skills (e.g., the ability to perform communicative functions involving speaking and listening). The learner modeling...

Controlling a complex dynamic system, such as a plane or a crane, usually requires a skilled operator. Such a control skill is typically hard to reconstruct through introspection. Therefore an attractive approach to the reconstruction of control skill involves machine learning from operators' control traces, also known as behavioural cloning. In the most common approach to behavioural cloning, ...

A skill transfer and improvement framework was designed and implemented to transfer skills to a simulated robot without the help of a robotics expert. A skill expert first learns to perform the desired task by maneuvering the robot and giving actuator commands using the keyboard. The framework is then used to transfer the expert’s skills to the robot by teaching the robot’s controller to perfor...

While some work has gone into developing specific learning environments, little has gone into clarifying the general issues that affect the acquisition of a complex skill, especially in a naturalistic setting. A study was made of an extremely complex skill, skiing, to determine why it has become so easy to learn. The goal was to analyze the features of a highly successful learning environment i...

The relations between premorbid adjustment, social skill, and domains of functioning (symptoms, social adjustment) were examined in a group of 107 schizophrenic, schizoaffective, and affective disorder patients. Premorbid sexual adjustment was moderately correlated with social skill in the schizophrenic and schizoaffective patients. Schizophrenic patients had the lowest premorbid adjustment and...

BACKGROUND Drug abuse is now-a-days one of the gravest social harms. Recent years have experienced a drastic rise in drug abuse among school and university students. Thus, the need for special attention to the issue is deemed important. The present study was conducted with the aim of assessing the impact of life skills training on promotion of drug abuse preventive behaviors. METHODS This fie...

INTRODUCTION There is paucity in the research on transfer validity of arthroscopic simulator training. The aim of this article is to determine whether skills derived from arthroscopic simulation are transferrable to the operating theatre and retained over time. METHODS A systematic review with rigorous criteria to identify the highest level of evidence available was carried out. The studies w...

This research is targeted towards the provision of support for designers in achieving, and measuring , Buildability whilst allowing for design Creativity and learning . This paper deals with the development of Skill Models as an approach to measuring Buildability in a CAD produced design . A Skill Model is specific to one construction task . A library of Skill Models is required for full measur...

Complex skills with aerial phases, such as somersaults or release-regrasp skills make up about 45 % of all elements in artistic gymnastics. The underlying mechanics of these skills have been studied extensively, and visual information is thought to assist gymnasts in skill performance. However, empirical evidence on the role of gaze behavior and its interplay with movement behavior in complex s...

BACKGROUND Previous studies of task-specific skills have suggested that a loss of technical performance occurs if the skill is not practiced for a six-month period. The aims of this study were to objectively demonstrate the learning curve for a complex arthroscopic task (meniscal repair) by means of motion analysis and to determine the impact of task repetition on the retention of this skill. ...
