introduction: collaborative testing is a learning strategy that provides students with the opportunity to learn and practice collaboration. this study aimed to determine the effect of collaborative testing on test performance and retention of course content in nursing students of shiraz university of medical sciences, shiraz, iran. methods: this quasi-experimental study was carried out on 84 st...

Using intelligent dialogue components, we can relate the isolated functions of information retrieval systems to larger tasks and help the user satisfy her information needs. Such dialogue components monitor the interaction between user and system and suggest what the user should do on the basis of her goals and the dialogue history. However, for these components to have the necessary flexibilit...

We present an annotation scheme and combinatorial authoring procedure by which a small base of annotated human-authored dialogue exchanges can be exploited to automatically generate many new exchanges. The combinatorial procedure builds recombinant exchanges by reasoning about individual lines of dialogue in terms of their mark-up, which is attributed during annotation and captures what a line ...

Current computing systems do not support human work effectively. They restrict human-computer interaction to one mode at a time and are designed with an assumption that use will be by individuals (rather than groups), directing (rather than interacting with) the system. To support the ways in which humans work and interact, a new paradigm for computing is required that is multimodal, rather tha...

This research investigates human dialogue variations by having simulated agents converse about a simple map navigation task using a computational theory of human dialogue strategies. The theory to be tested is that agents have a variety of strategies which they use in goM-directed dialogue for deciding what information to include, how to present it, how to construct references, and how to handl...

Situated dialogue systems that interact with humans as part of a team (e.g., robot teammates) need to be able to use information from communication channels to gauge the coordination level and effectiveness of the team. Currently, the feasibility of this end goal is limited by several gaps in both the empirical and computational literature. The purpose of this paper is to address those gaps in ...

In this paper, we present a synchronous text-based communication tool, referred to as Adaptive Communication Tool (ACT), which provides capabilities for adaptation and personalization. ACT supports both the free and the structured form of dialogue. The structured dialogue is implemented by two types of Scaffolding Sentence Templates (SST); i.e. sentence openers or communicative acts. The capabi...

We propose a plan-based approach for responding to user queries in a collaborative environment. We argue that in such an environment, the system should not accept the user's query automatically, but should consider it a proposal open for negotiation. In this paper we concentrate on cases in which the system and user disagree, and discuss how this disagreement can be detected, negotiated, and ho...
