Second Announcement


After successful conferences held at Pécs, Hungary (2007), Hagenberg, Austria (2009), Hluboká nad Vltavou, Czech Republic (2010), Novi Sad, Servia (2012), Halle, Germany (2014) and Targu Mures, Romania (2016) we are delighted to announce that the CADGME conference continues. The team from Department of Mathematics and Center for Informatics and Systems of the University of Coimbra has volunteered to host the conference in 2018 in the beautiful city Coimbra. As for the last CADGME conferences we want to create a forum for all European colleagues, and for all interested academics from around the globe to exchange ideas and nurture collaboration. We hope that you will join us in Coimbra on 26 – 29 June 2018.

Keynote speakers

Jaime Carvalho e Silva (University of Coimbra, Portugal)
The challenges schools face with the development of Computer Algebra

Kristof Fenyvesi (Jyvaskyla, Finland)

Call for papers

The aim of the conference is to continue offering a forum for academics in Europe in closer connection with Western European colleagues to share their experiences and practices with technology-assisted mathematics teaching with colleagues from all around the world. Hence, we kindly invite colleagues - everyone from everywhere - to participate and contribute to the conference. The language of the conference is English.

How to contribute

Contributed talks

The talks will be given in parallel sessions; the length is 20 minutes plus 10 minutes for discussion.
Research results can be presented on posters. There will be time allocated to present and discuss

Working groups

Talks will be organized around the conference topics as shown in the list below. In working group sessions plenty of time will be allocated for in-depth discussion of talks/papers.

You can see the list of proposed workshops below. We encourage participants to prepare for the workshops according to the description and bring technologies if requested. Workships usually last
for 1.5 hours.

Electronic submission of proposals and abstracts

We are delighted that we have already received more than 80 working group, workshop and presentation proposals for CADGME 2018. But knowing that some of you may not have found yet
the time to make a submission, we have extended the deadline of the abstract of contributed talks
and posters. The new deadline for these is 3 April, 2018.

Submissions must be made through Easy Chair:

Publication, proceedings


Abstracts of contributed talks and posters will be published on the conference proceedings website. The maximum length is 300 words.

Journal Publication

If you wish to publish a paper in a journal about your talk at the CADGME 2018 conference you will be able to submit it to special issues of the following peer-reviewed journals:

 The International Journal for Technology in Mathematics Education (IJTME)
 The Electronic Journal of Mathematics & Technology (eJMT)
 Acta Didactica Napocensia (ADN)

Topics for contribution

The conference will be arranged around four important themes — Teaching, Learning, Curriculum and Assessment — using any digital tools. In the past years, we paid particular attention to
Computer Algebra Systems (CAS), Dynamic Geometry Software (DGS), Theorem Proving Systems
(TPS) and combinations of these technologies, but we would like to open to new horizons in
technology-related areas not only mathematics, but science, engineering, technology and arts
education (so called STEM disciplines). This includes, but is not restricted to, contributions to the
following fields.

 The impact of technology uses on mathematics and STEAM teaching
 The changing role of the teacher
 Teacher learning
 Distance learning and digital tools
 Arts for the teaching of mathematics

 The impact of digital tools on students’ learning
 Students’ attitudes toward digital tools
 Understanding and knowledge with respect to digital tools
 Algebraic skills and digital tools
 Creativity and digital tools

 Design of learning environments and curricula
 Implementation of curricula and classroom practices
 Innovative practices
 Promises of digital tools for curriculum development and administration

 Assessment with digital tools
 Web-based assessment systems
 Problem solving and stepwise use of digital tools
 Intelligent Assessment
