Student survey demonstrates that students do not favor the use of e-chalk in the classroom but favor other technology use.

A good visualization draws the viewers attention to the comparisons it attempts to convey whether through the use of color and size. It also has clear labels to separate section and make understanding the data easier. The use of size must also correlate to the actual data and not have random sizes or different shapes .

This visualization is based on a sample of 55 high school students and their opinion on the use of technology in the classroom and how it affects their learning experience. It serves as a good visualization due to the fact that it differentiates between its different sections not only using labels but color coding each section. Whether using a bar graph or circles, the shapes used to represent the data is consistent and the size corresponds to the percentage or number of students in each category. The captions make it clear what the visualization is attempting to convey.

A viewer can clearly see that students agree that the use of PowerPoint and smart boards is beneficial to their learning; however, the use of E-chalk and E-chalk forums was generally viewed as not beneficial. Students remained relatively neutral when asked whether typing assisted them in learning. It is clear that students favor certain technology in regards to education; however, the neutral sections tended be the largest in each data set except "I learn better when teachers use PowerPoint slides."
