This paper describes a prototype of a simulaled physics student that learns by interacting with a human tutor. The system solves physics problems while showing its work on a work· station screen, and the tutor can intervene at cenain points during problem·solving to advise the simulaled studenL This prototype constitutes an initial cognitive task analysis of the skill of learning from a tutor, ...

The apparent difficulty that humans experience when asked to manage dynamic complexity might be related to their inability to discriminate among familiar classes of objects (i.e., flawed recognition). In this study we examined the change in individuals’ recognition ability, as measured by the change in the similarity of decisions they made when confronted repeatedly with consistent dynamic situ...

the present study was conducted to compare the effect of individual and group pre-task planning on efl learners’ accuracy and complexity in speaking. to fulfill the purpose of the study, 60 intermediate female learners at the first grade of high school were chosen by means of a sample preliminary english test (pet) and randomly divided into two experimental groups of 30 students; the individual...

This paper summarizes a model of interaction for CVEs inspired by the process followed in human communication in the real world, detailing both the main elements and the communication process itself. The model proposed copies some properties of the real world communication but also allows the easy integration of Task Analysis to the design of CVEs, helping the developer in the design of the app...

  Task-based learning and teaching in the realm of teaching young learners is still considered an adventure since very few experimental studies to date have tackled its applicability in that age group. The present research was an attempt to find out whether using task-based reading activities has any impact on the development of text comprehension in Iranian young learners studying English as ...

: This study aims to explore the relationship between syntactic and lexical complexity and also the relationship between different aspects of lexical complexity. To this end, speech monologs of 35 Iranian high-intermediate learners of English on three different tasks (i.e. argumentation, description, and narration) were analyzed for correlations between one measure of sy...

Text Classification is an important research field in information retrieval and text mining. The main task in text classification is to assign text documents in predefined categories based on documents’ contents and labeled-training samples. Since word detection is a difficult and time consuming task in Persian language, Bayesian text classifier is an appropriate approach to deal with different...
