Building STEM Connections Brick By Brick

Richard Espinola, Ph.D., an electronics
engineer at the U.S. Naval Research Laboratory in Washington D.C.,
spends his spare time mentoring a local FIRST® Lego® League (FLL)
team.
It may sound like child’s play, but FLL participants
are serious about building Science, Technology, Engineering, and
Mathematics (STEM) connections brick by brick.
FLL is a
hands-on robotics competition that introduces students to STEM
concepts in a fun way. The program is now a global competition with
more than 670,000 participants.

As team mentor, Espinola helps his team
understand the year’s challenge and guides them in their
problem-solving process. He also applies for DoD STEM grants on
behalf of the team.
It all started when Espinola talked to
neighbors and they realized that while their children were
interested in a robotics team, there were none in their area. So
along with another parent, he set out to start one.
Neighborhood word of mouth was enough to draw participants. Their
team ranges from seven to nine students, but has largely retained
the same membership.
“We’ve been competing since 2017 with a
slight break last year because of COVID-19,” Espinola said.
Though the pandemic may have changed the format and processes of the
competition, the challenge continued for FLL teams. Interest in
participating actually increased during the pandemic, Espinola said.
“Fortunately, the FIRST program still had a virtual option
so we were able to participate,” Espinola said. “It was different
from the typical school day during the pandemic because they could
interact with their friends and work together. I think my son and
his friends enjoyed it. They really made the best of it.”
The
organization’s acronym FIRST describes its mission best: For
Inspiration and Recognition of Science and Technology.
“It’s
a way for the organization to introduce the STEM field, specifically
robotics,” Espinola said. “It was developed to show the kids a way
to learn and apply it in a competition.”
While teams get a
break over summer, the start of the school year signals the start of
a new challenge. Challenges follow a theme and require each team to
develop a novel solution to a problem using robotics. Past
challenges have included addressing real-world topics like climate
and quality of life for the handicapped population.
“It’s not
just some abstract idea or science fiction,” Espinola said. “It’s
factually relevant to today’s problems. They show how using robotics
and technology can address real-world problems.”
The
participants enjoy the sense of community instilled by working
toward a common goal.
“My favorite part of FLL is
collaborating with my group to find solutions to real-world
problems,” said Stephan Lugovoy, an FLL team member.
One of
the main ways Espinola advises the team is by helping them break
down both the problem and the workload. Just like a team of
researchers at NRL, the students divide responsibilities among team
members. One may be in charge of background research or design,
while others work on electrical components or coding.
“In the
adult world, you hardly ever find an engineer strictly working
alone,” Espinola said.
The team members get a head start in
future careers by learning valuable STEM skills like how to make an
aerodynamic design and code in Python, a computer programming
language.
“Python is exactly the language a lot of NRL
scientists and engineers are using,” Espinola said. “I use it in my
field. It’s a great start for elementary and middle school kids to
start understanding the software development now.”
While
they’re learning difficult concepts, the participants are focused on
the fun they’re having.
“My favorite part of FLL is the
coding,” said Nikita Lugovoy, an FLL team member. “Helping code the
robot was always a fun and crucial task.”
Espinola believes
that the skills and lessons learned during the challenge process
will stick with children.
“A lot of times you’re doing math
or physics and it’s all abstract,” Espinola said. “There’s nothing
that makes it practical to you, but when you apply that to a problem
solving situation then you’re able to remember how to do that math
problem.”
This past season, Espinola’s team had its best
finish ever in a competition. Even if the primary prize is only
bragging rights, Espinola said it’s exciting just to see his team’s
final product in action after weeks of hard work.
“I’m very
happy NRL allows its employees to do activities like this and
supports them,” Espinola said. “In a way this is an extension of
what I do at NRL, but in a fun approach that helps teach kids.”
Spending time with a mentor inspires students to pursue a career
in STEM. Espinola should know. His own father was an engineer and
his mentor. “I looked up to him,” Espinola said. “When I went to
college and learned more in terms of STEM classes, it continued to
inspire me to pursue further graduate education.”
Without
mentors like Espinola, a program like FLL cannot function. He
encourages other scientists and engineers to consider being a STEM
mentor. “If you can manage the time required and you’re willing to
be patient with young learners, it’s very rewarding,” Espinola said.
