EFFECTS OF USING CALCULATORS (TI-92) ON LEARNING TRANSFORMATIONAL GEOMETRY

The present study aims at finding out the effects of using the advanced calculator TI-92/Cabri in teaching transformational geometry on teacher students ’ attitudes, geometric thinking levels and achievement. The subject of study, i.e. the participants in the introduction to geometry course, were 78 students from freshmen elementary school mathematics education students at Hacettepe University, Ankara, Turkey. Three instruments were used in the present study to find out the relevant factors and effects of TI-92/Cabri aided/supported geometry teaching. The data were gathered by means of the designed instruments and analyzed by using PC-SPSS. In the analysis, several tests were used in order to understand the effects of various factors on the attitudes and achievement. This statistical analysis compares the mean scores of each group and reveals whether this differences significant or not
