How I Use It
I have used this website for a variety of purposes. I have used it to obtain quick descriptive statistics for real-world applications in probability and statistics lessons and activities. For example, finding census data (the population of NY, the percent of Asian Americans, etc...). We use this data to create our own graphs and compute our own statistical analyses. Then we use the website to check our work.
I have also used it to perform quick calculations when I do not have a calculator available. It is much less expensive than a graphing calculator. Students also like how it takes much less time to input their functions and data.
Finally, I have used it to obtain visualizations of functions. For example, I have had students use it to do an investigation on transformations of linear functions by comparing the graphs of y = x, y = x + a, and y = ax. A similar investigation can also be done with higher order functions.
This is a powerful search engine with an expansive database. The speed, thoroughness, accuracy, and multiple representations are impressive! You can input anything (words, numbers, symbols, etc...) and the technology will output an up to date linguistic analysis, curated data, dynamic computations, and visual and tabular outputs. This variety of information meets the needs of students with multiple intelligences and learning styles. It also enables conceptual understanding and entices students curiosity as opposed to requiring students to memorize the one right answer.
