ncte writing computer scoring grading machine automated

  • Conclusions that computers can score as well as humans are the result of humans being trained to score like the computers (for example, being told not to make judgments on the accuracy of information). 
  • Computer scoring systems can be "gamed" because they are poor at working with human language, further weakening the validity of their assessments and separating students not on the basis of writing ability but on whether they know and can use machine-tricking strategies.

  • And by the time kids get to college, professors assume they already have this skill.
  • Students quickly gain the ability to detect if a top-ranked page about Martin Luther King Jr. was actually posted by white supremacists.

  • “crap detection 101,” as digital guru Howard Rheingold dubs it, isn’t easy. One prerequisite is that you already know a lot about the world.

  • Pan grimly concluded that students aren’t assessing information sources on their own merit—they’re putting too much trust in the machine.
  • High school and college students may be “digital natives,” but they’re wretched at searching.
  • In 1955, we wondered why Johnny can’t read. Today the question is, why can’t Johnny search?

    "Google makes broad-based knowledge more important, not less. A good education is the true key to effective search. But until our kids have that, let's make sure they don't always take PageRank at its word."
