Application of GeoGebra to the teaching of vector algebra

The study was conducted to explore how GeoGebra can enhance the teaching and learning of vector algebra, thereby improving students' conceptual understanding of vector algebra.The study employed a pre-experimental design, which is a one-group pretest-posttest approach, where the researcher had the opportunity to assess the impact of GeoGebra integrated instruction on students' learning outcomes after it has been used as an instructional tool.The statistical comparison between pre-test and post-test scores, indicates a massive increase in the average performance with a mean pre-test score of 29.90 to a post-test mean of 63.30.While the standard deviations for both pre-test (21.28) and post-test (16.9281) scores demonstrated higher variability, the paired t-test results revealed statistically significant difference between the pre-test and post-test mean scores.Further analysis performed indicates a very large effect size suggesting that GeoGebra was valuable to teaching of vector algebra.The descriptive analysis from SPSS revealed more insights into students' perceptions and confidence regarding the use of GeoGebra.A greater proportion of students acknowledged the advantages of the tool, such as improved comprehension and interactive visualization, whereas a minority maintained a neutral stance.The ratings on the instructional materials underscored the importance of diverse resources, with suggestions for improvement focusing on more interactive tutorials and varied exercises.Overall, GeoGebra depicts as promising and potential educational tool for vector algebra instruction and the need to be integrated into our mathematics education at all levels.
