In partnership with the University of the Philippines-National Institute for Science and Mathematics Education Development, the Department of Science and Technology-Science Education Institute held its third face-to-face training for science teachers in Panglao, Bohol, with the focus on the basics of GeoGebra.

GeoGebra is an interactive geometry, algebra, statistics and calculus application intended for learning and teaching mathematics and science.

Fifty mathematics teachers from the Department of Education Division of Bohol participated in the three-day training composed of three modules designed to enhance the proficiency of the teachers in using GeoGebra.

The course gave an overview of the GeoGebra software and its basic functions and interface. Usage and modification of the number, angle and integer sliders to construct dynamic objects were also discussed.

The teacher-participants were also able to use the input bar to plot points, graph circles, calculations and graphs on polynomial functions to piecewise functions.

After the lecture sessions, the participants developed their GeoGebra applet. The  team with the best applet focused on Trigonometric Ratio (www.geogebra.org/m/kwba8hpn), while the second centered on visualizing Tangent and Secant Functions (www.geogebra.org/m/kqxuzxaq) and the third applet covered the properties of Parallel Lines.
