1. Improving the students performance using digital tools in geometry instruction
Nagy Hunor – math teacher in middle school
Dr. Kupán Pál – math teacher at Sapientia University
Tg-Mures - Romania

2. My experiment using GeoGebra
I talk about:
Teoretical parts:
Practial parts:
traditional
alternative
Digital tools
My experiment using GeoGebra
Conclusions

3. Traditional methods: Limits: If don’t edit a right figures how
can proof with the wrong figures
If don’t have spatial vision, they
make wrong 3d figures

4. Alternative teaching methods:
teamworks
Differentiated education
Alternative schools, classes:
Step by step
Waldorf

5. UNIVERSAL BASIC INTELLIGENCE MODELLING
UBIM
UNIVERSAL BASIC INTELLIGENCE MODELLING
I want to try
It was very expensive

6. E-learning system’s, AEL
AEL - Advanced E-Learning

7. Teaching software’s
Euklides
Geonext
GeoGebra

8. My experiment: Experimental group Test after the traditional teaching
Use GeoGebra
Test after experiment with GeoGebra

9. The experimental group
VII-th class (13 years students)

10. The test: Problems type:
I. part: True or False answers, or fill in the missing parts
II. part: Multiple answers, find the right one
III. part: Problems that solves need detailed solutions

11. Using GeoGebra – VI.th classes
1. The segment. The angle.
2. Editing triangles
3. Parallelism, perpendicular lines.
4. Medians,altitudes,angle bisectors,perpendicular bisectors
5. The triangles properties.

12. Using GeoGebra- VII.th classes
1. The quadrilateral properties
2. Pythagorean theorem. Distance between two points.
3. The isosceles right angeled triangle - hypotenuse
4. The right angeled triangle - altitude, area
5. The equilateral triangle – altitude, area.
6. The trapezoid.

13. Using GeoGebra- VIII.th classes
1. Positions between wo lines.
2. Positions between line and plane.
3. Positions between two planes.

14. Tests evaluation: experiements results

15. Conclusions The students like to use GeoGebra
The feedback come from more students
In VI-th class experiment the perfomance is visible
I want to make an experiment in VIII-th class with another experimental groups
I also like’d to give this experiments to other teachers in our region in middle and in primary shools.
