This paper describes the use of discourse analysis for understanding the affordances technology provides for teaching and learning. Due to the proliferation of technology in the classroom, teachers must critically examine the tools they put into place in order to achieve learning goals. Technologies can either reinforce or refute educational discourses, and the teacher must understand the discourses embedded in technology and how those can be leveraged in the classroom. Works Cited

The “big dig” the “big dig” (the central artery/tunnel project) has been complex and challenging. located in boston, massachusetts, this tunnel is eight lanes wide and three-and-a-half miles long. what is most amazing about this tunnel is that it is constructed under a major highway and skyscrapers located in boston’s financial district. construction crews used “clamshell excavators” during this dig. these machines carved narrow trenches, and then a special substance was pumped into the trench to keep the dirt from caving in. finally, steel beams were lowered into the trench and concrete was pumped in. one problem that engineers faced while constructing the tunnel is the fact that the soil beneath boston is extremely loose and soggy. engineers solved this dilemma by freezing the soil and pumping very cold water into pipes beneath the city. to strengthen the soil even further, a special type of glue was injected into the ground to with the consolidation of the soil. 23 which phrase best defines the word excavator as used in the passage? a. a device used to measure underground temperatures b. a device used to level uneven surfaces c. a device used to move heavy objects d. a device used to dig holes
