Meanings of morphological categories are an indispensable component of representation of sentence semantics. In the Prague Dependency Treebank 2.0, sentence semantics is represented as a dependency tree consisting of labeled nodes and edges. Meanings of morphological categories are captured as attributes of tree nodes; these attributes are called grammatemes. The present paper focuses on morpho...

People may want to recall a multitude of experiences and information from everyday life. Human memory, however, has its limitations and can be insufficient for capturing and allowing access to salient information and important details over time. A variety of tools — primitive, analog, or digital — can complement natural memories through recording. Throughout history, in fact, record keeping and...

As a broader array of communication tools is developed, designers of learning environments need a better understanding of what kinds of communication each medium is best suited for. Each of the new media have different affordances and constraints. One of our principles for the design of learning environments is “Render unto each medium what it does best.” This paper is an attempt to state some ...

The purpose of this study was to investigate the effect of using synchronous and asynchronous communication tools in online group activities to develop collaborative learning skills. An experimental study was implemented on a sample of faculty of education students in Mansoura University. The sample was divided into two groups, a group studied using synchronous communication tools, and the othe...

Aiming to offer a framework for blended learning to the teaching of proof theory, the present paper describes an interactive tutorial, called TryLogic, teaching how to solve logical conjectures either by proofs or refutations. The paper also describes the integration of our infrastructure with the Virtual Learning Environment Moodle through the IMS Learning Tools Interoperability specification,...
