In the Wednesday presentation, all our classmates have a good presentation, I can learn different research skills from each group. group 1 has the slideshow which highlights the referent text to remind themselves of the important part of the research. group 2 was using photography to compare the change of zoning each period. group 3 uses the data to tell us about the economy in their research. and the last group was using the map data to analyze and compare the population, land use at different times. in conclusion, I do not only get the information about MetroTech also learn how to use a different source to present the information to our audience.
