researchers have suggested that interactional feedback which is between teacher and learner during their writing is associated with l2 learning because it prompts learners to notice l2 forms. this paper reports a classroom-based study that investigated the role of feedback in socio-cultural theory. in this study, 12 efl learners performed on three writing tasks and were provided with a three-st...

introduction: evaluation of students’ learning in clinical education system is one of the most important and challenging issues that facilities in this field have been facing. the present study aimed to evaluate the role of feedback during evaluation in increasing emergency medicine residents’ clinical skills. method: the present experimental study was performed on all second year emergency med...

Age-related deficits are seen across tasks where learning depends on asocial feedback processing, however plasticity has been observed in some of the same tasks in social contexts suggesting a novel way to attenuate deficits. Socioemotional selectivity theory suggests this plasticity is due to a deliberative motivational shift toward achieving well-being with age (positivity effect) that revers...

Do students activate conceptual and procedural knowledge simultaneously when learning fraction addition? In grounded feedback, student actions on a target, to-be-learned representation are reflected in a more familiar feedback representation to promote conceptual learning within procedural practice. An experiment with 163 4th and 5th graders shows improved learning with a grounded feedback tuto...

Procedural learning of skills depends on dopamine-mediated striatal plasticity. Most prior work investigated single stimulus-response procedural learning followed by feedback. However, many skills include several actions that must be performed before feedback is available. A new procedural-learning task is developed in which three independent and successive unsupervised categorization responses...

Providing exploratory activities prior to instruction has been shown to facilitate learning. However, questions remain regarding the provision of guidance during the exploration phase. In this study, we replicated and extended a previous experiment by examining the effects of feedback during exploratory problem solving for children with varying levels of prior knowledge. Ninety-five children (M...

BACKGROUND Redundant training and feedback are crucial for successful acquisition of skills in simulation trainings. It is still unclear how or how much feedback should best be delivered to maximize its effect, and how learners' activity and feedback are optimally blended. To determine the influence of high- versus low-frequency expert feedback on the learning curve of students' clinical proced...

In this work a user centered procedural modeling framework is proposed which combines rule based content generation with the concepts of recommendation systems. Using the ACGAX modeling language, artists are able to write grammar scripts for the creation of diverse and complex 3D scenes, controlled with a simple goal notation. These scripts are evaluated and executed by the system to generate 3...
