Visual Representation of Semantic Network of Bulgarian Nominal Inflectional Morphology

In this work1 we offer a space representation of a model of Bulgarian nominal inflectional morphology for the feature of definiteness using orthogonal semantic networks. A geometrical interpretation of the encoded network is based on a visual representation of orthogonal semantic relationship

Stereometry activities with DALEST

This book reports on a project to devise and test a teaching programme in 3D geometry for middle school students based on the needs, knowledge and experiences of a range of countries within the European Union. The main objective of the project was the development (and testing) of a dynamic three-dimensional geometry microworld that enabled the students to construct, observe and manipulate geometrical figures in space and which their teachers used to help their students construct an understanding of stereometr
