Michigan Tackles its STEM Challenge--with CTEq's Help

March 9, 2017

In the past few years, Michigan has roared back to life as a magnet for STEM jobs like engineering, and the state's employers are right to wonder if they will be able to fill those jobs with qualified people. Fortunately, we see strong signs that Michigan leaders are on the case.

On Tuesday, I was honored to testify before Michigan's House Education Reform Committee about Change the Equation's efforts to help the state identify and scale K-12 STEM education programs that are most likely to have an impact. CTEq's STEMworks has already helped rigorously-vetted programs, such as Engineering is Elementary and Project Lead the Way, receive $1 million in state funds. We have high hopes for much more to come.

Efforts like these are very timely. For a state that was ground zero in the Great Recession, Michigan has an uplifing story to tell about STEM jobs. For example, it has been a great place for engineers. The number of engineering jobs in the state grew 11 percent from 2006 and 2016, compared to a meager 2 percent for the nation as a whole. Engineering jobs will probably grow another 13 percent between 2016 and 2026, faster than the 11 percent projected for the nation. That amounts to tens of thousands of engineering jobs.

Will employers be able to find the engineering talent they need over the coming decade? That's a harder question to answer. There is some reason for concern. First, they cannot fully tap the state's minority talent. Black, Latinos, and American Indian Michiganders make up 23 percent of the state's college-age population but receive only 5 percent of engineering degrees and certificates:

Underrepresented minorities in engineering

Women are almost as scarce in the field:

Few female engineers

There's good news on the horizon: In late 2015, the state adopted academic standards in science that formally incorporate engineering principles. If other states that have adoped similar standards are any indication, all Michigan students, regardless of race or gender, will soon learn the fundamental principles of engineering.

Programs like those in STEMworks will only help.

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.

Where are the Girls? STEM Career & Technical Education

January 12, 2017

Career and technical education is no longer the forgotten stepchild of education reform. The plight of jobless Americans took center stage in the turbulent Presidential election and raised the stakes for creating pathways to the middle class that don’t pass through the ivy-fringed gates of four-year colleges. In fact, jaded Congress watchers believe that CTE may be one of the few issues that will win bipartisan support in 2017.

That’s good news, but converts to the CTE cause will soon discover what CTE experts have known for a long time: namely, that the gender gaps in CTE’s STEM subjects are every bit as large as gender gaps in advanced math and science classes. In fact, those gaps are growing. To create broad opportunities for all their students, states must meet this problem head on.

To gauge the depth of the challenge, we reviewed federal data on high school students who concentrate in one of four critical STEM CTE fields: Health science, information technology, manufacturing, and science & technology.[1]

The lion’s share of female high schoolers concentrating in STEM CTE study health science, while male students are more evenly distributed:

Not surprisingly, high school girls dominate health science, but they are scarce in the other three career clusters.  The imbalance has gotten worse since 2007/08:

CTE Gender Imbalance is Growing

In science and engineering, girls held steady at a measly 25 percent. [1]

The news isn’t all bad for girls. They dominate in health sciences at a time when the healthcare sector is growing quickly and middle-skill jobs in health command a strong wage, at least for those who go on to earn a two-year technical degree.

Still, the gender imbalances should concern everyone. it’s more than a bit troubling that segregation by gender is getting worse. As fields like healthcare and computing continue to grow, we cannot draw most of our talent from only half of the population. In addition, a growing body of research tells us that organizations benefit from gender diversity in the workplace.

What’s to be done? As with most problems that really matter, the solutions are multifaceted, ranging from formally recruiting girls as early as middle schools to redesigning CTE curricula to avoid gender stereotypes and providing CTE teachers professional development on how to create a welcoming environment for all genders. 

(Check out this handy primer on professional development for a fuller list.)

Employers should continue making the case for gender balance while identifying employees who can serve as mentors: female employees in advanced manufacturing, for example, or male nurses. Governors can use their bully pulpit to advance campaigns that encourage gender diversity in middle-skill STEM jobs. Career and technical educators can work with their schools and districts to design targeted student recruitment strategies that break through the gender stereotypes.

Each state or community might find a different set of solutions, but none can afford to ignore the problem. State leaders must dedicate themselves to improving matters. The Carl D. Perkins Career and Technical Education Act of 2006, which is likely to be reauthorized this year, requires states to report on their progress in improving gender equity in CTE. It is not yet clear, however, whether states will suffer any federal consequences if they fail to reach their targets. There is little appetite for federal sanctions these days.

The solution is up to all of us. After all, everyone has a major stake in fostering a creative and robust middle skills workforce. We won’t get there if we allow boys and girls to go their separate ways.


[1] Health Science, Information Technology, Manufacturing, and “STEM” are career clusters in the National Career Clusters Framework. For the purposes of this analysis, we have renamed the STEM career cluster as “Science & engineering” to avoid confusion with our own definition of STEM, which includes the other three career clusters. The Science & engineering cluster includes “planning, managing and providing scientific research and professional and technical services (e.g., physical science, social science, engineering) including laboratory and testing services, and research and development services.”

[2] Data reveal that male and female enrollments more than doubled—growing by roughly 120 percent each. That said, girls did not improve their relative position.

New data: Are Women Making Gains in Computing and Engineering?

November 22, 2016

In the past three weeks, we have been examining recent data on computing and engineering degrees. We have already reported encouraging news about the overall growth in those degrees and mixed news about the extent to which African Americans and Latinos are sharing in that growth. Today's blog examines how women are faring in these critical fields. Our verdict: there is not much to celebrate yet, but there may be some glimmers of hope.

Computing:

Let’s start with the glass half empty. The following chart looks far too familiar, even though it contains some new data on the gender disparity in computing degrees:

 Women still lag far behind in computing degrees

While men have surged past their 2004 peak by a healthy 27 percent, women just barely cleared their 2003 peak last year.

And the above chart conveys the good news, relatively speaking: it represents trends in bachelor’s and higher degrees, where women fared the best. Women have lost far more ground in degrees and certificates below the bachelor’s level:

For women, computing credentials below the bachelor's level plummet

Women’s share of bachelor’s and higher degrees tumbled by more than six percentage points since 2001, but their share of sub-bachelor’s credentials plunged by more than 20 percentage points over the same period.

Why is this a concern? Economists expect computing jobs to surge in the coming decade, and computing jobs that require less than a bachelor's degree are no exception. For example, the Bureau of Labor Statistics estimates that, between 2014 and 2024, jobs for computer support specialists and web developers will grow by 11.6 and 26.6 percent, respectively. Over that decade, these two occupations will generate 265,000 job openings whose average pay well exceeds the $36,200 average salary for all occupations. The past decade and a half have seen women's prospects for such good jobs plummet.

And now for the glass half full: While some of these data seem discouraging on their face, the charts do suggest that we have finally stanched the bleeding. The decline in computing degrees and certificates going to women has leveled off.

There may be much better news to come. The last five years have seen an unprecedented national focus on girls in computer science. It will take a few years yet for that focus to affect college graduation data.

Engineering:

At first blush, there seems to be more to celebrate in engineering than in computer science. Women made small gains in engineering degrees at the bachelor’s level and above, even as they earned a declining share of credentials below the bachelor’s level:

Engineering: women gain in bachelor's and higher degrees, fall in subbacalaureate

The share of engineering degrees that went to women climbed 2.4 percentage points between 2009 and 2015. The decline in sub-bachelor's degrees is less concerning in engineering than in computing, because the Bureau of Labor Statistics projects little or no growth in engineering technology jobs, which generally require less than a bachelor's degree.

 Things are moving in the right direction for women in engineering, but too slowly. At this rate, women will have to wait roughly three quarters of a century to reach parity with men.

A closer look at the data reveals stronger trends in master’s and doctoral degrees since 2001:

Engineering: women make the largest gains in master;s and doctoral degrees

Women's share of master's degrees rose by almost four percentage points between 2001 and 2015, and their share of doctoral degrees advanced by more than six and a half percentage points. Women's percentage of bachelor's degrees experiences a slow and steady slump before 2009 but women have regained all of their lost ground since then. Initiatives to diversify graduate degrees may be bearing fruit. 

These data suggest that initiatives to diversify graduate degrees may be paying off, which in turn can promote more female role models among U.S. engineering professors[i] That said, we still have far to go before women receive a proportionate share of doctoral degrees.

It is simply too early to tell whether these charts carry the seeds of hope. They reflect what was going on in elementary and secondary schools as long as 20 years ago, and it will take at least as long to see the full impact of our current efforts to encourage girls to pursue STEM fields. If anything, they remind us that we cannot take our foot off the gas.


[i] Data are scarce on how many women serve on engineering faculty. Researchers should study whether women’s progress in doctoral degrees is affecting the gender balance of engineering departments.

New Data: Minorities Gain Some Ground in Computer Science and Engineering Degrees

November 9, 2016

On October 26, we shared some good news about degrees in computer science and engineering: Since the recession, they grew much faster than degrees and certificates overall. Today, we take a closer look at students of color in those fields, and we have at least some good news to share--mixed with much that should concern us.

For every race, the number of bachelor’s and advanced degrees in computer science and engineering has grown faster than the overall population between 18 and 24.  In other words, your typical black, Latino, or white person of college age was more likely to earn one of these degrees in 2015 than in 2001.  On balance, that’s good news for everyone.

 Growth in cs & engineering degrees chart

Of course, it’s far too soon to declare victory, because a small number degrees can grow by a large percentage and still be a small number of degrees.

The more important question is whether people of color are earning degrees in proportion to their share of the population. In the best of all possible worlds, for example, Latinos would earn 21 percent of degrees, because they comprise 21 percent of the college-age population.

The reality falls far short of that ideal, but there are glimmers of hope.

African Americans

For African Americans, the picture in computer science is mixed. The share of bachelor’s degrees they receive has fallen off since the high point of 2007, but new data suggest that their share of master’s degrees surged for almost a decade before retreating somewhat after 2013. African Americans are actually overrepresented among Americans who receive master’s degrees.[i] 

Computer science: Af Am rise in master's and slip in bachelor's

Why? A report in Science Magazine cited this trend in Master’s degrees as early as 2011 and speculated that efforts to attract more African Americans into computer science graduate degrees were bearing fruit. That may well be true, but disappointing trends in bachelor’s degrees will surely thwart further progress in advanced degrees.

Alas, it is hard to find much good news about African Americans in engineering. Their share of bachelor’s degrees has declined slightly since 2005, and their share of master’s degrees has barely kept pace with population growth.

Af Am gain no ground in engineering degrees

This problem may arise from the fact that African American students have limited access to advanced high school classes—like calculus—that can be gateways to engineering in college. 

Latinos

Latinos earn a smaller share of computer science degrees than African Americans do, but they are making steady, albeit slow, gains, mostly at the bachelor’s level.

Latinos slowly narrow the gap in computer science degres

If you look hard, you can see the gap between Latinos' share of bachelor's degrees (the dark blue line) and their share of the population (the red line) narrowing, especially after 2009. Since that year, Latinos’ share of bachelor’s degrees has risen roughly 2 ½ percentage points while their share of the population rose by less than a percentage point. In the previous six years, their share of bachelor's degrees had risen more slowly--roughly 1 ½ percentage points.

Latinos are also making gains in engineering:

Latinos narrow the gap in engineering degrees

Their share of bachelor’s degrees has risen almost four percentage points since 2007, roughly twice as fast as their share of the population over the same period. Master’s degrees have seen nearly parallel gains since 2009.

Why have Latinos gained in some areas where African Americans have been treading water? It’s hard to say without more evidence. More research could help us learn from our successes and replicate them.

 

Despite some encouraging signs, it’s hardly time to pop the champagne corks. If the pace of change doesn’t pick up, it would take more than a decade for Latinos to close engineering gaps, and even longer for them to close computer science gaps. African Americans would never close the gaps in bachelor’s-level engineering and computer science.

Yes, we have made some progress, but minority students’ current K-12 experience will impose a low ceiling on that progress. As CTEq’s state-by-state Vital Signs website demonstrates, students of color still have the least access to the resources, facilities, and classes that best prepare students for college-level STEM.

There are carefully-vetted strategies and programs that can help students overcome hurdles like these. For dozens of programs that can prove they’re making a difference, take a look at CTEq's STEMworks honor roll of effective STEM education programs. For all their accomplishments, programs like these are not going to close the gaps unless the nation rallies around them with the public and private commitment and resources they need to reach many more young people.

Incremental progress just won’t do as long as STEM literacy remains a gatekeeper to individual and national prosperity.

Stay tuned next week for the most recent data on women in computer science and engineering.
