K-12 Engineering and Technology Classes Have Hit the Big Time

August 29, 2017

K-12 engineering and technology have gone mainstream. A new poll from Phi Delta Kappa shows that "technology and engineering classes" top the list of Americans' priorities for school school quality.

Results: aspects of school quality

This is a startling finding. Not long ago, teaching engineering or technology classes in grade school or high school was an exotic idea. Neither subject fit easily into most school curricula, and few states' academic standards acknowledged either. Engineering was the stuff of college, and computer science seemed to atrophy within high schools as rapidly as it overtook the world beyond them.

The polling results crown years of effort. Pioneering initiatives such as Engineering is Elementary and Project Lead the Way have exposed millions of K-12 students to engineering. Computer science has seen a more recent resurgence, fueled by efforts of organizations such as Microsoft, Oracle, and Code.org. The Next Generation Science Standards, which most states have either adopted or adapted, have enshrined engineering and technology in states' formal expectations for what their students should know and be able to do. We at CTEq joined with these and other advocates to make the case for careers in engineering and computing.

And now the obligatory disclaimer: We still have far to go to deliver on Americans' new vision of school quality. Computer science classes remain scarce, and most students still go through school without learning much about engineering. Even so, the nation has made big gains in a relatively short time.

And now public opinion is on our side.

Eye-Popping Gains in Computer Science!

August 2, 2017

All too often, stories about education reform start with herculean efforts and end with anemic results. Fortunately, the story of at least one large national reform movement is poised to have a happier ending. The push to expand computer science in K-12 is already yielding impressive results.

According to early data from The College Board via Code.org, the numbers of high schoolers taking any Computer Science AP more than doubled between 2016 and 2017. The numbers for girls and students of color grew even faster--135 percent and 170 percent, respectively. The College Board's new test--AP Computer Science Principles--contributed most of those gains.

Girls rose from roughly 18 percent to 27 percent of all test takers from 2013 to 2017, and students of color advanced from 12 to 20 percent over the same period. If we keep to this pace, we can close the gaps in gender and race/ethnicity in just over a decade. For ed reform veterans who are used to the snail's pace of change in education, those numbers are eye-popping.

Technology companies, visionary state leaders, and organizations like The College Board and Code.org have fueled this growth through their full-throated advocacy and support. Employers raised a hue and a cry about computer science in schools and joined other advocates in urging states to guarantee computer science classes every high school. The College Board created Computer Science Principles to introduce students to "the underlying principles of computation," and organizations like Code.org have helped prepare students for the test through new courses and teacher training.

CTEq just included two such courses in STEMworks, our honor roll of programs that stand up to rigorous review. Code.org's AP Computer Science Principles course "introduces students to the foundational concepts of computer science and challenges them to explore how computing and technology can impact the world." 

Computer Science Discoveries, also from Code.org, targets seventh- to ninth-graders, empowering them "to develop digital and physical projects using creativity and problem solving in a fun, collaborative environment." Both courses are filling a vacuum in our nation's middle and high schools, where computer science courses have been as rare as hen's teeth, even as the tech revolution has raged just beyond their walls.

Indeed, last year, CTEq released grim data on access to computer science classes by race and ethnicity::

Race determines access to computer science classes

Given the new data on AP participation, we have high hopes that these numbers will change for the better:

Of course, that won't be the whole story. CS advocates have a monumental task ahead of them, even as they expand access: They must train thousands more teachers to teach the new courses, and those teachers need to lift their students over the AP tests' high bar.

No easy task, but we're off to a good start.

The High Stakes of Diversity for Washington State

May 18, 2017

Washington State may have a bright future if it maintains its dominance in the tech sector, but that could be a tall order. Lack of diversity in the STEM workforce could be the state’s Achilles heel, and that challenge has its roots in K-12.

It should surprise no one that STEM jobs pay in a state with companies like Microsoft and Boeing call home. STEM jobs in Washington State may well grow 15 percent in the coming decade, and the state’s STEM wage premium is enormous:

Washington State STEM Earnings

Unfortunately, people of color are least likely to reap these rewards. Notice for example, who earns degrees and certificates in computing or engineering:

WAshington State diversity of computing credentials

WAshington state diversity of engineering credentials

The green line in each chart represents minorities as a percentage of the college-aged population. The blue line represents the percentage of degrees and certificates that went to minorities. The wider the space between the two lines, the less well represented minorities are.

If you squint, you might seem some improvement in the last half-decade or so, but the gaps remain enormous. Black, Latino, and American Indian Washingtonians at state colleges and universities are still much less likely than their white or Asian peers to receive credentials in STEM.

The problem starts early, and it might get worse. For example, science scores for white eighth-graders in the state have climbed steadily since 2009, while those of black and Latino students have languished:

WAshington State science scores

Math scores follow similar trends, and black students fare the worst.

One possible reason: Underrepresented students of color seem to have less access to STEM learning opportunities. Teachers of African American students are less likely to say they have the resources they need to teach science:

Washington State resources to teach science

Access to lab equipment and supplies is also very uneven, and again students of color get the short end of the stick:

Washington State lab supplies

Even those students of color who have the potential to succeed on Advanced Placement tests in STEM often don’t take them:

Washington State Students who could thrive in AP don't take tests

Many may attend schools that don’t offer AP classes or their equivalents.

These disadvantages can add up over time and exacerbate the gaps. In Washington State, Blacks and Hispanics hold only seven percent of computing jobs and five percent of engineering jobs, even though they make up 15 percent of the state’s working-age population. For a state that will need all the STEM talent it can get, such inequities can be devastating.

Fortunately, STEM advocates in organizations like WashingtonSTEM have worked with state leaders to put STEM education at the forefront. The state has embraced robust new science standards. It aims to increase students’ access to computer science education. It is bringing STEM into early childhood education. It will take time for policies like these to affect the workforce, but they are a vital down-payment on the state’s prosperitys.

Quick take: New Jersey's Computer Science Challenge

March 23, 2017

The impending talent shortage in computer science has been in the news for some time now. New Jersey could face a particularly sharp challenge.

A Quick look at our Vital Signs for the state reveals some troubling trends. No other state has seen a steeper decline in the number of degrees and certificates awardedn in computer science and related fields:

Declining degrees in computer science

This trend is perplexing, because demand for computing talent in the state remains robust. According to Economic Modeling Specialiststs, International, the state boasts one of the highest concentrations of computing jobs in the nation [1], and prospects for future growth look robust:

New Jersey STEM job growth

These conflicting trends do not bode well for New Jersey. That said, there may be glimmers of hope. The state is among the growing number that allows high schoolers to count computer science credits towards graduation requirements, and charts like the ones we share here will surely push state advocates to go even farther. After all, grim realities can be very compelling.

New Data: New Science Standards Are Boosting Engineering in Schools

February 21, 2017

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:

NGSS is boosting class time

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:

Individual states ramping up engineering & tech

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:

NGSS boosting engineering in classrooms

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.

NGSS students more likely to notice tech & engineering

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 money to 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.

NOTE: We were not able to assess the impact of NGSS on another jurisdiction that adopted them before 2014: Washington, DC. Unfortunately, the 2015 science NAEP did not include state-level results for DC.
