Today\u2019s youth has grown up with digital technology and has lived immersed in environments populated by computers, video games, digital music players, video cameras, cell phones, and thousands of other toys and tools of the digital age. It is for this reason that the authors are persuaded that education in the 21st century should be directed to use digital resources as well as digital ways of teaching in all subjects. Mathematics needs digitization and the paper deals with the development of dynamic sketches for geometry teaching and learning. The concept of dynamic geometry is introduced and discussed together with problems and examples of application of dynamic geometry software. The model for interactive geometry visualization is described and the implementation of this model is reported. Together with former topics an experimental research is presented, which is based on the use of the interactive pre-constructed sketches by the dynamic geometry software Geometer\u2019s Sketchpad. At last the didactical approach of the experiment is analyzed, the results of the experience are described and conclusions and discussions are proposed.<\/p>","DOI":"10.4018\/jdldc.2012040101","type":"journal-article","created":{"date-parts":[[2012,12,11]],"date-time":"2012-12-11T16:25:15Z","timestamp":1355243115000},"page":"1-19","source":"Crossref","is-referenced-by-count":3,"title":["Towards Digital Competencies in Mathematics Education"],"prefix":"10.4018","volume":"3","author":[{"given":"Egle","family":"Jasute","sequence":"first","affiliation":[{"name":"Vilnius University, Lithuania"}]},{"given":"Valentina","family":"Dagiene","sequence":"additional","affiliation":[{"name":"Vilnius University, Lithuania"}]}],"member":"2432","reference":[{"key":"jdldc.2012040101-0","author":"K.Ala-Mutka","year":"2011","journal-title":"Mapping digital competence: Towards a conceptual understanding (JRC Technical Notes)"},{"key":"jdldc.2012040101-1","doi-asserted-by":"publisher","DOI":"10.1787\/218525261154"},{"key":"jdldc.2012040101-2","author":"M.Barber","year":"2007","journal-title":"How the world\u2019s best-performing school systems come out on top"},{"key":"jdldc.2012040101-3","first-page":"41","article-title":"Visualization and exploring mathematics using information technologies.","author":"V.Dagiene","year":"2007","journal-title":"Information Sciences"},{"key":"jdldc.2012040101-4","doi-asserted-by":"publisher","DOI":"10.1504\/IJSHC.2008.020480"},{"key":"jdldc.2012040101-5","doi-asserted-by":"publisher","DOI":"10.1007\/BF02504683"},{"key":"jdldc.2012040101-6","unstructured":"Eurydice.
