The Effect of Interactive Computer Program on Student Accomplishment in Teaching Trigonometry

Happy Lumbantobing


The aim of this research is to consider the effect of using an interactive computer program in trigonometry learning. Counterbalance research design was used with a sample of 43 students. The sample was spread in two experimental classes, namely acceleration classes of 24 students and regular classes of 19 students. Both classes received the same learning treatment, namely learning designed using GeoGebra software and ordinary learning without using GeoGebra software. Research data were analysed applying the SPSS 24 program for Windows with the significance level (two-tailed) determined to 0.05. The analysis shows that there are significant differences in learning outcomes between the two types of learning. The superior learning outcomes were obtained in learning that was designed using GeoGebra software.
