Abstract
Mathematics education researchers studied technology use in a vast majority of high school mathematics courses. One of the main questions considered is related to the integration of calculators for graphing functions: are graphic tools beneficial or not for understanding the underlying concepts? Generally, we expect that students would have positive attitudes towards graphs after visualizing them on calculators and then following with more conceptual algebraic or computational operations. In our study we consider the following research question in high school mathematics curriculum: Are there any benefits of learning logarithmic functions by first properly using graphing calculators as an initial tool introducing the concept as compare with traditional method that provides algebraic definitions and practice of arithmetic calculations for sketching the graphs? During this research project we worked with students in two Algebra 2 courses learning about graphs of logarithms using these two different approaches. Collected data was analyzed using statistical methods and we present our results.
