We consider the concept classes of DNF formulas and unions of discretized, axis-parallel d-dimensional boxes in discretized d-dimensional space with respect to several different learning models. In the model of learning with queries we present an algorithm to learn unions of boxes. We introduce a model of teaching that prevents illicit communication between the teacher and the leaner but that c...

In this chapter a modern approach to e-teaching scenarios at the university level is introduced that focuses on the teacher. This approach covers content-related and communicational components of an e-education scenario. Content creation and delivery via Internet, as well as teacher-learner communication is shown from the point of view of the teacher. The content related part of an eteaching sc...

The topic of this thesis is learning through social interaction, consisting of experiments that focus on word acquisition through imitation, and a formalism aiming to provide stronger theoretical foundations. The formalism is designed to encompass essentially any situation where a learner tries to figure out what a teacher wants it to do by interaction or observation. It groups learners that ar...

Research in the acquisition of patient interviewing skills by medical students has dealt mostly with the evaluation of the effectiveness of various teaching programs and techniques. The educational approaches (i.e., the tutor-learner relationship and learning atmosphere) have rarely been discussed. These approaches may be grouped into: a) "teacher-centered" (didactic), in which the students are...

this paper investigates learner-initiated responses to english language teachers’ referential questions and learner initiatives after teachers’ feedback moves in meaning-focused question-answer sequences to analyze how interactional practices of language teachers, their initiation and feedback moves, facilitate learner initiatives. classroom discourse research has largely neglected learner init...

This study investigates the andragogical and pedagogical teaching philosophies of online instructors at the California State University, Long Beach in the Spring Semester of 2010. Drawing from reflective adult education theory, this article proposes a new model for this reflective adult education theory. It is either the helping relationship (andragogical philosophy) or the directing relationsh...

recent interaction studies havefocused on the relationship between interactional feedback and l2 development.despite the large body of knowledge in this regard, few studies have examinedlearners’ preferences for interactional feedback. besides, different findingshave been reported concerning learners’ preferences for feedback and none hasexamined the factors accounting for the variation in the ...
