In the context of Digital School I and Digital School II projects, ETL team in collaboration with external partners participated in the digital transformation of interactive mathematics textbooks. The team developed 1600 micro-experiments addressing mathematical concepts of primary and secondary education.

For the development of the micro-experiments the team used 3 authoring tools (MaLT2 and ChoiCo, Geogebra 5.0.), 5 ETL focused authoring tools, as well as other open source design environments such as Scratch.

221 micro-experiments were developed with MaLT2 authoring tool (120 for middle school, 74 for high school, 26 for primary school, 1 for technical secondary school).

Selected examples:

• Unfinished Triangle.
• Dihedral angle.
• A rectangle, but not square.

6 micro-experiments were developed with ChoiCo authoring tool

33 micro-experiments were developed with Cube World focused authoring tool

84 micro-experiments were developed with Abacusfocused authoring tool

33 micro-experiments were developed with Numberline focused authoring tool

59 micro-experiments were developed with Broken Cacluclator focused authoring tool

16 micro-experiments were developed with Multi-scale focused authoring tool

1087 micro-experiments were developed with Geogebra 5.0. authoring tool

All micro-experiments are hosted in the national repository for learning objects Photodentro.
