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
I talk about: traditional • Teoretical parts: • Practial parts: alternative Digital tools My experiment using GeoGebra Conclusions
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 Lecture Explanation Disscusion Illustration Project Homework
Alternative teaching methods: • teamworks • Differentiated education Alternative schools, classes: • Step by step • Waldorf
UBIM UNIVERSAL BASIC INTELLIGENCE MODELLING • I want to try • It was very expensive
E-learning system’s, AEL • AEL - Advanced E-Learning
Teaching software’s Euklides Geonext GeoGebra
My experiment: • Experimental group • Test after the traditional teaching • Use GeoGebra • Test after experiment with GeoGebra
The experimental group • VII-th class (13 years students)
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
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.
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.
Using GeoGebra- VIII.th classes • 1. Positions between wo lines. • 2. Positions between line and plane. • 3. Positions between two planes.
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.
