Jana,
Technology is advancing so rapidly, one sometimes wonders "how can I stay up-to-speed with all the technological adavnces?". That said, evaluation methods still have to align with this fact: Do they measure learning? Any system (fancy or plain) has to measure the degree (or lack of) learning if it is to be effective.
Some of my teachers do mutiple choice exams via student laptops where each students test has the same questions but ramdomy rearranges the order of the questions, and even the order of the selections in a question! If the student leaves the page, the test ends. Results are instantaneously graded and reported. Pretty fancy. That's one extreme. Then I think about sitting around in a discussion and posing questions, listening to answers, evaluating the correctness and thought process, and assigning a grade based the level of participation and engagement (along with correct responses). I know, low tech, but who's to say which system evaluated the students learning better? I think we have to plan, think about, and be thorough in our determination about how best to evaluate student learning. And certainly, no one way is the best in all situations!
