Abstract Feedback provided by mathematics teachers usually addresses procedural skills and, to a much lesser extent, other competencies such as conceptual understanding or engagement in mathematical practices. As most previous literature has studied feedback on homework video prompts, how provide the classroom is poorly understood. Here, sixteen lessons taught five were purposefully sampled fro...

We describe a utility-based feedback control model and its applications within an open access digital library search engine – CiteSeerX, the new version of CiteSeer. CiteSeerX leverages user-based feedback to correct metadata and reformulate the citation graph. New documents are automatically crawled using a focused crawler for indexing. Those documents that are ingested have their document URL...

the objective of the present paper is to shed some light on peer feedback in efl writing courses. in recent years, with regard to teaching writing, there has been a total shift of approach, from product-orientation to process-orientation. a key component of the latter is peer assessment in which learners read each other's compositions and provide feedback to the writer, based on the teache...

Meditation is becoming increasingly popular as a topic for scientific research and theories on meditation are becoming ever more specific. We distinguish between what is called focused Attention meditation, open Monitoring meditation, and loving kindness (or compassion) meditation. Research suggests that these meditations have differential, dissociable effects on a wide range of cognitive (cont...

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...

Background/introduction Anti-tumor immune response caused by High Intensity Focused Ultrasound (HIFU) therapy has been a subject of controversy. Most agree that the response is more likely to be induced by mechanical, rather than thermal effects of HIFU. The goal of the current work was to study the effect of HIFU-induced liquefaction of a tumor on tumor-specific and non-specific T-cell mediate...
