Meeting of participants, informal discussion.

Welcome (Jan Zahradnik), opening of the Workshop (Markus Hohenwarter, Pavel Pech),

short report about the first teacher seminar in Budweis on 13.02.2013 (Jan Zahradnik).

13:30 - 14:30

Lecture of Dr. Šárka Gergelitsová (invited speaker - Gymnázium Benešov)

Plane geometry problems and their evaluation in GeoGebra applet environment

Plane geometry problems are not very popular with many students and the process of teaching and learning geometry is usually accompanied by many difficulties. In addition to the solving of the problem, paper-and-pencil drawing

is time consuming for students and requires some drawing skill. Not only is the evaluation itself a complicated problem but evaluating this kind of tasks is time consuming for teachers. Consequently, students do not solve as many

problems as necessary to make them experienced enough in solving such problems. The automatic evaluation of students´ answer to plane geometry tasks  is able to speed up the process a lot, but due to its complexness

it has been beyond the capabilities of known systems until now. We want to present a new online system and report on our first experience of using it. Students solve assigned tasks in GeoGebra applets embedded in web pages and

submit their answers to the server. The server evaluates their answers instantly. This approach influences the plane geometry problem solving strategies.

14:30 - 15:00

Discussion on lecture.

15:30 - 16:00

Coffee Break

15:30 - 16:45

Each Austrian teacher (5) presents the materials of the special lessons done in his/her school, describes
