A report issued by the UK's Organization for Economic Cooperation and Development has evaluated how technology in classrooms affects test results, and found that the availability of computers provides "no noticeable improvement" to students' test scores. According to the report, "Students who use computers very frequently at school get worse results." Also, "high achieving school systems such as South Korea and Shanghai in China have lower levels of computer use in school." The organization warns that classroom technology can be a distraction if implemented unwisely, and it also opens the door to easy ways of cheating.
Teaching math does not much improve one's grade in English. Teaching writing does not much improve one's grade in math.
It isn't Reading, Writing and Arithmetic anymore. Learning computer skills is a good and necessary part of the schoolhouse curriculum. You can read, write and 'rithmetic with the best of of them but that won't help you if you have to apply for the job online. But a dumbass that knows his way around a URL can get a job anywhere.
Separate skill set.... the availability of computers provides "no noticeable improvement" to students' test scores.
Not if the teachers are educated....opens the door for easy cheating
