Robotic failure is all too common in unstructured robot tasks. Despite well designed controllers, robots often fail due to unexpected events. How do robots measure unexpected events? Many do not. Most robots are driven by the senseplan-act paradigm, however more recently robots are working with a sense-plan-act-verify paradigm. In this work we present a principled methodology to bootstrap robot...

the current study is an attempt to investigate the particular role learners' vocabulary knowledge plays in their reading comprehension performance. it intends to determine whether breadth and depth of vocabulary knowledge are related to efl learners' reading comprehension, and to investigate which one of these variables, that is, depth or breadth of vocabulary knowledge, makes a more important ...

The complement between pull and push learning modes is believed to be contributable to enriching students’ learning experiences. Podcasting, a push technology, can be used to push teaching materials to the students’ handheld devices, allowing them to study without any geographical and temporal constraints. The students can then revise the materials according to their own preferences. This expli...

Second language (L2) researchers have long recognized the potential benefits of incorporating pronunciation instruction in language curricula (e.g., Arteaga, 2000; Castino, 1996; Elliott, 1995, 1997; González-Bueno, 1997; Lord, 2005; Major, 1998; Moyer, 1999; Terrell, 1989; among others), and have investigated a variety of training types both in and out of the classroom, meeting with mixed succ...

Podcasting is used commonly recreationally and is now increasingly used in education. The technology for podcasting is readily available, easy to use and inexpensive, making it an attractive option for providing additional flexible learning resources for students. However, little is known about how podcasts are used by students and the implications for learning. This paper describes how podcast...

This paper challenges the dominant perception evident in the literature that mobile podcasting is primarily a medium for knowledge transmission. It describes why and how mobile audio learning can be facilitative, active and integrated, and how it can involve diverse voices, including those of students, in ways that usefully disrupt didactic pedagogy. Audio is described as an active learning env...

The advent of podcasting offers opportunities for students to learn while performing another activity. While podcasting is advocated by many as helping to learn anywhere and anytime, research indicates that it is not so easy for people to do two things at the same time. Two experiments were set up to examine the effect of performing a secondary task while learning with an iPod. In the experimen...

Until now, research on podcasting in education mostly examined teacher created podcasts in K-12 and higher education. This paper explores podcasts in professional learning across several genres of podcasts. Using a popular typology of podcasts, teacher created, student created and professional development podcasts (King & Gura, 2007), this paper compares, contrasts and reveals the potential of ...

Despite the fact that portability was perceived as one of the major benefits of podcasting as a teaching and learning tool, little evidence has been found of users taking advantage of this feature for academic use. This paper reports on a major study (1886 responses) of iTunes U users. The analysis compares the responses of those participants who use static devices to play the materials they do...

Compound words are a difficulty for German speech recognition systems since they cause high out-of-vocabulary and word error rates. State of the art approaches augment the language model by the fragments of compounds in order to increase lexical coverage, lower the perplexity and out-of-vocabulary rate. The fragments are tagged in order to concatenate subsequent equally tagged fragments in the ...
