The current study examines the impact of different task types on learning prepositions in form and meaning- focused interaction enhancement- based classes. The participants were 57 second Year University students enrolled in three intact lab classes at Tabriz Islamic Azad University.  The first group was provided with form-focused interaction enhancement, the second with the meaning-focused int...

Decision table decomposition is a method that decomposes given decision table into an equivalent set of decision tables. Decomposition can enhance the quality of knowledge discovered from databases by simplifying the data mining task. The paper contains a description of decision table decomposition method and their evaluation for data classification. Additionally, a novel method of obtaining at...

• Many evaluations of spoken dialogue systems are focussed on defining and collecting quantitative measures. • Other studies concentrate on users' perceptions only. • Only a few studies describe quality ratings in terms of both system properties and user judgements. • We used the PARADISE framework (i) to gain insight into the factors affecting the user satisfaction of a spoken dialogue system,...

This study aimed to investigate the impact of task sequencing, along +/- reasoning demands dimension, on writing task performance in terms of accuracy.  The study was motivated by Robinson’s Cognition Hypothesis (CH) as well as previous studies investigating the relationships between task complexity and second language production. The participants of the study were 90 intermediate students at t...

Course generation enables the automatic assembly of course(ware) adapted to the learner’s competencies and learning goals. It offers a middle way between traditional pre-authored “one-size fits all” courseware and manual resource look-up. Such an assembly requires pedagogical knowledge, represented, for instance, as expert system rules or planning operators. In this article, we describe the cou...
