I read the report and its really a great report  shows how the calculator benefit the students and the teachers as well , this report and also the article discuss the benefit of the calculators also shows some of the bad side affect both some parents and some teachers think , especially those old parents and the teachers they  not use to these technology , also some of the new generation think that calculators prevented student from progress which is not true the report has mention many myths about the use of calculators. which really convinced me a lot, calculators meant to  be helpful for student in computation which is the low level part of math , its true we all knows how to compute but when the student reach to a higher level need time to think and explore more than  wasting the time for computation.
