Strongly disagree.
Science is a method, using tools which change very slowly.
The most important tool, reasoning ability, changes not at all.
At the postgraduate level, currency with the developing literature in your subdiscipline is critical.
In high school, it's stupid. Every second spent on "the latest discoveries" is a second wasted, since the half-life of new discoveries is less than the time it will take a high school sophomore to graduate from college.
Memorizing constantly changing (and half-wrong) facts has produced a generation of science illiterates.
