New Data: New Science Standards Are Boosting Engineering in Schools
Let’s usher in this year’s National Engineers Week with some good news. We’ve crunched some numbers, and it looks like efforts to make engineering part of the K-12 curriculum are beginning to pay off.
Why? Our guess is that the Next Generation Science Standards (NGSS) are succeeding in their aim to integrate engineering and technology into science classrooms. These standards debuted in April 2013, and eight states adopted them by the end of that year: California, Delaware, Kansas, Kentucky, Maryland, Rhode Island, Vermont, and Washington State.
We had a look at data from the National Assessment of Educational Progress (NAEP) eighth-grade science test to see if schools in those eight states were teaching more engineering and technology. NAEP is a good tool for this exploration, because it surveys teachers and students about engineering and technology in the classroom, among other subjects.
What we found suggests that the Next Generation Science Standards are making a difference in schools. Between 2011 and 2015, teachers in the first states to adopt the standards increased the amount of class time they spent on engineering and technology:
Sticklers might note that these gains could have occurred before April 2013, when the new standards burst upon the scene. Unfortunately, we can’t settle that question definitively, because we lack data from that year. Still, the data we do have make a very strong case for NGSS. States that adopted the standards after 2013, or that never adopted them at all, saw smaller gains between 2011 and 2015.
One striking finding from our analysis is that the early adopter states started from behind. This pattern holds when we examine each of those states individually. In 2011, eighth-graders in our eight NGSS states were less likely than their peers in the nation as a whole to spend at least “some” time on engineering and technology. The picture looked dramatically different in 2015:
What does it mean to spend “some” or “a lot” of time on engineering and technology? The results of another NAEP survey question offer at least some insight: “About how often do your science students discuss the kinds of problems that engineers can solve?” Here again, it appears that the NGSS states started well behind their peers but caught up:
These data reinforce our conclusion that teachers in NGSS states have grown more likely to focus on engineering. So far, so good. But are their students noticing the difference? The results of another NAEP survey item suggest that they are…but only up to a point.
Again, the NGSS states have made swifter progress than other states, but it seems a tad early to declare victory. Even though more than half (52 percent) of eighth-graders have science teachers who spend time on engineering and technology, far fewer (31 percent) seem to have noticed that fact.
Of course, students may still be learning about engineering and technology without realizing it, but their lack of awareness is troubling. After all, the Standards themselves specify that students should “understand the work of scientists and engineers” and “recognize” that what engineers do is “a creative endeavor.” We know we haven’t reached the goal line if so many students don’t yet recognize engineering or technology when they see it.
On balance, though, we should be optimistic. We have strong evidence that standards can make a difference in the classroom, and in a relatively short time. In fact, engineering and technology are probably more pervasive now than our numbers suggest: almost two years have passed since the 2015 NAEP test, and more states have adopted the Standards.
The ultimate test of the Standards’ success, of course, will be students’ performance. That verdict will have to wait a bit longer. States are still developing tests that incorporate engineering–and they can use federal moneyto do it. And a representative sample of U.S. eighth-graders will take NAEP’s next Technology and Engineering Literacy Assessment in 2018.
In the meantime, states and districts must continue the hard work of creating teaching materials, training teachers, and providing supplies to make engineering real in the classroom. If they succeed, future Engineers Weeks will bring even better news.
