A big question asked by concerned people and industry leaders across the Nation is waiting for an answer… How will current and future generations stay competitive in an increasingly, complex, global economy? A high-performance education program involving a blend of Science, Technology, Engineering and Mathematics (STEM) — is promising solutions as its building momentum within post-secondary and kindergarten-through-grade 12 (K-12) education. 

The STEM Robotics team project is demonstrated to an enthusiastic audience of all ages.

The dynamic learning created from STEM’s project based curriculum is contagious for a growing number of students. And the program’s appeal is spreading to parents, public schools and corporate sponsors who are looking for ways to get involved in supporting technology learning through secondary education. Even the U.S. Congress solidly supports the critical initiatives driving STEM Education, which is primarily funded through the National Science Foundation (NSF.)

Enthusiasm and excitement were experienced by those viewing students’ technology project presentations.

A Basic Overview Of A STEM Magnet Program

.

By the 21st century, digital technology had transformed global manufacturing and commerce by accelerating STEM related industries. The skill-sets, training and knowledge of entry-level applicants was noticeably falling behind. Standards for learning, used in our public educational system, were now becoming outdated. Nationally, educators needed a new, comprehensive learning approach to inspire, explore and motivate students’ achievement in the global dynamics of STEM.

Today, the Nation’s public schools place greater emphasis on introducing STEM related content to both teachers and students, starting as early as grade school. This program strategy allows all students of varied backgrounds, ethnicities and socioeconomic levels, gain access to learning projects associated with science and technology. By presenting young students with thoughtful STEM lesson plans, they are more likely to engage in the discovery process of even the most technical subject matters. Entering middle school, students are learning accelerated levels of science and technology content, which helps them decide if they wish to enroll in a high school, offering a focused curriculum. The STEM Magnet Program pulls in a diversified population of students, engaged and motivated by their earliest learning experiences.

 Evolution And Development Of STEM Education

.

Richard Blais, Chairman of the technology department for the Shenendehowa Central School District in Upstate New York, developed a curriculum in 1986, to support students’ interest in studying engineering. To enable enthusiasm and confidence in students, core courses included; pre-engineering and digital electronics, infused with energetic and interactive learning environments. The curriculum’s proven a success, attracted philanthropist, Richard Liebich, who partnered with Blais to set up, Project Lead the Way (PLTW.)

Within 10 years of PLTW’s founding, a dozen high schools in New York State adopted the program. Within the next few years high schools in 30 states were using PLTW’s “Pathway to Engineering Program.” Soon after, PLTW was a major national program, which used innovative activities of project and problem-based assignments. Further adding to PLTW’s momentum and success was the enthusiastic support corporations showed by endorsing and contributing financial resources towards the program.

Mark Sanders’, 2009 STEMmania article in The Technology Teacher, cites the STEM acronym first being used in the 1990’s. The National Science Foundation (NSF) started using “SMET” as a reference for “science, mathematics, engineering and technology.” A department, program officer complained “SMET” sounded similar to “smut,” so “STEM” became the suitable replacement. It would take more than a decade for the public to recognize STEM’s referenced meaning.

The support and enthusiasm for STEM Education is displayed by an impressive turnout for the District’s first STEM EXPO Fair.

  

The Challenge Of Integrative Education: Transcending Barriers And Perceived Domains Found Within Science, Technology, Engineering and Mathematic Education

.

Perhaps the greatest test for a STEM Magnet Program will involve achieving the goal, of course/subject integration. As a career, technical and education (CTE) instructor, I’ve heard this complaint more than any other from students — “why do I have to learn this subject, it doesn’t relate to other things I’m learning or anything I’ll ever need to know!?” In truth, all subjects and courses taught in school share dynamic connections, we as educators need to do more in helping students see their associations.    Core sciences and engineering education programs have traditionally maintained strict disciplinary lines, known as silos. This shortsighted disconnect is generally not found in highly competitive industries, where the imperative is to find solutions which will “payoff” in the shortest amount of time. Industry’s necessity to cut through the process, for realizing greater profits is an important lesson plan for all STEM Programs. The realized profit for a student is — being taught how to quickly adapt new, comprehensive and sometimes-unconventional learning strategies to gain a competitive advantage.

Benefits/Advantages For Both Students And The Schools They Attend

.

Developing a STEM magnet program helps a school district align its resources towards assisting students preparing for college and universities, which specialize in related technical studies. An additional advantage the program offers a student pursuing a post secondary education is — an institution will most likely accept the applicant’s enrollment request based on the knowledge and technical skills achieved through a STEM Magnet Program.

     U.S. industries have increasingly cited the lack of qualified technical applicants they need as a reason not to hire more employees. The shortage of people with necessary STEM skills has motivated corporations to contribute their resources of funding, mentoring and sponsorship towards public education’s technology learning programs.

Community exhibitors at the STEM EXPO Fair include corporate sponsors of STEM education.

Parents and community groups have eagerly supported STEM programs. Student’s parents are critical stakeholders who quickly realized the impact the program was having  — seeing impressive scholastic and attitude improvements with their children.

STEM Education Uses Progressive Learning Strategies To Develop Critical Learning And Self-Discipline Within a Student 

.

As STEM Education attempts to accelerate student development by modifying the standard teacher-centered classroom with more independent learning. The curriculum encourages project-based learning, problem solving and discovery, which empower the students to engage their cognitive skills to find solutions. This form of learning develops greater self-confidence in students and it opens channels among the students themselves to interact thru peer-to-peer learning. These spontaneous collaborative activities are self-organized learning events and they naturally promote leadership within the group. It has been well documented, knowledge transferred from experience in peer-to-peer activities are highly successful forms of learning.

Students enrolled in STEM Programs are encouraged to engage and connect with others by refining their presentation skills.

  

Tangible Returns In Personal Development Through Teamwork And Leadership

.

Over the past five years I’ve had the opportunity to teach in a variety of classroom environments using a CTE curriculum. It’s remarkable seeing how engaged students are with learning their STEM subject matter. These same students are much more likely to openly contribute and share their ideas in a classroom discussion using the critical thinking skills they’ve learned to develop.

Most often, the STEM classes are more like being in a college environment, requiring a minimum amount of classroom management, as the students are self-motivated to complete their assignments and move on to the next project. Generally, the level of leadership development and volunteerism is noticeably higher in STEM classes due to the program’s emphasis on teamwork, self-confidence and academic achievement. These personal development qualities are valuable assets for students when applying for college admission and later — when entering the career of their choice.

Improving Forecast For Employment Opportunities Using STEM Education

.

As STEM Magnet Schools continue to place their graduates into secondary education, followed by the students’ successful careers in STEM related industries — STEM Education will help transform the American education landscape. If STEM Education can sustain its momentum, the future horizon looks bright for our youth to achieve economic opportunities on a global leveled playing field.

Boeing’s 787 Dreamliner Historic First Flight From Paine Field, Everett, WA.

Multimedia and video essay by: David Johanson Vasquez © All Rights

The presentation includes: Video of a 787 Dreamliner first flight, aerospace structural testing practices, aerospace engineering design practices, aerospace manufacturing, fiber composite materials.  

My video camera kit had been prepared months in advance, ready at a moment’s notice for the first maiden flight of Boeing’s 787 Dreamliner—21st Century entry airliner.  Finally, Dave Waggoner, the director of Paine Field Airport, queued me into the date to witness an evolutionary advance in commercial aviation.

Cameras Packed And Ready To Go

My home is only a short drive from Boeing’s production facilities at Paine Field, Everett; so I was motivated to video record this “making of 21st century aviation history.”  Due to initial production delays, an entire year went by before I received reliable news of the 787-8 wide-body, long-range airliner was ready for her much-anticipated maiden flight. The 787 Dreamliner’s first flight was at 10:27 a.m. PST, December 15, 2009.

Experienced As A Boeing Scientific Photographer

The 787, first flight video project brought back some great memories from my former career as an aerospace photographer with the Boeing Company.  When first hired on by the iconic aviation leader, my assignment involved providing video support for the Everett plant’s test engineering groups, who were conducting bulkhead fatigue test on airline fuselages. In preceding years, some airlines began experiencing inflight catastrophic failures related to metal fatigue. Tragically  the determined cause was from the age of the aircraft, specifically, stresses created when interior cabins went through an excessive number of pressurization cycles.

An event in the 1980s, of a Boeing 737 was dramatically documented as it safely landed with a massive section of the fuselage missing. The Aloha Airlines, 737 jetliner experienced a catastrophic failure due to metal fatigue. The metal fatigue issues caused from pressurization cycles on the aircraft were not clearly understood, so the FAA required engineering test to research the potential safety threat.A series of highly documented Test were conducted over a period of months; going through thousands of pressurized cycles.  The purpose was to recreate what a jet airliner physically experiences when the cabin is repeatedly pressured and unpressurized — as in every-time an airliner takes-off, gains altitude and eventually returns for its landing. Our team of scientific photographers had series of video cameras, strategically placed within the test bulkhead, which sat shrouded in layers of protective coatings, in a remote section of the Everett facilities. Over-pressurizing the bulkhead eventually caused the anticipated failure, announced  by a thunderous sound of cracking metal. The  bulkhead  test was well documented using various engineering test methods and imaging equipment. Valuable test data gathered was immediately analyzed, studied and put to methodical use for redesigning, engineering and manufacturing safer jet airlines.

Boeing’s Traditional Practice Of Over-Engineering

It’s been my experience, which confirms for me, what commercial pilots and engineers claim regarding Boeing’s reputation with its conservative practice of “over-engineering” their aircraft.  Historically, an over-engineering approach has proven itself as a life saving benefit — with countless Boeing aircraft surviving horrific damage… yet, still landing safely. Documentaries on WWII aircraft feature  shot-up Boeing aircraft returning safely, is an example of over-engineering.

For teams performing test  monitoring, with elaborate configured structures,  attached string gauges and actuators trying to force a break of an airplane part — the aerospace test may go on for days, or even months — the experience feels like sitting in bleachers for hours while watching slow-motion glacier races in progress.  All the invested resources of  time and effort, which goes into these aerospace component test,  helps to assure the flying public’s safety and the airlines performance records.

Engineers enjoy seeing how much torturous abuse their designed support systems will take before they bend, crack or break.  At the instant  a component does finally fail [normally, after far exceeding the range of what the it was designed to do] you’ll hear a loud noise caused from a test-object going beyond its limit. The sound of a breaking part, ends the tension of monitoring a test for hours or days — in an instant, the group of test engineers and technicians start cheering like a goal was scored by a home team in a stadium full of their fans.

Carbon Fiber Future In Aviation

One of many significant technological improvements for the new long-range, wide-body 787 Dreamliner, is a high percentage of composite, carbon fiber materials used in its construction. The amount of composite, materials employed in today’s aircraft have substantially increased from when it was initially developed  and used in military aircraft.  I recall, how amazingly light wing spares made of carbon fiber composite materials are, when moving them under lighting setups at Boeing’s Gateway studio.  It was fascinating observing and photographing the manufacturing of composite materials, as the process involves using massive heated autoclaves to form predesigned sections for aircraft structures.Now, remember the bulkhead test from a previous paragraph?  Carbon fiber composites eliminates the issue of metal fatigue associated with pressurizing  passenger cabin space.  Less concerns over metal fatigue allows for more pressurization  in the cabin for passenger comfort  — more importantly, the  integrated use of composite materials ensures greater safety, with substantially less risk to the structural integrity of the airliner.

Is Boeing’s Reliance On Outsourcing The Main Culprit For The 787 Dreamliner Being Grounded In A Global Lockdown?

In the past 15 years, Boeing’s upper management has broken formation from its traditional engineering leadership and replaced it by promoting executives with business and marketing backgrounds. The current Boeing regime embraces an outsourcing strategy, unfortunately, this trend of maximizing profits for shareholders has been on going with U.S. companies for the past two decades. Negative consequences of replacing an engineering management with a business one is clearly apparent in the power transmission industry — deregulation & marketing-driven-management  in the electric power industry has significantly placed this essential infrastructure at risk [overstretched power grid, vulnerable outdated high-power transformers.] Please see my multimedia essay – Will the Last People Remaining In America, Turn the Lights Back On? :http://sciencetechtablet.wordpress.com/tag/solar-storm-testimony-to-u-s-senate/                                           

                                                                                                                                                                                                 

A heavy dependence  on  foreign outsourcing is cited as a cause for unforeseen 787 production delays. Consistent, quality control monitoring becomes problematic when components are manufactured offsite, as result these issues can sometimes lead to extended,  unanticipated problems.

Outside vendors are capable of producing equal, if not superior quality components to that of Boeing in some technical areas. In fact, there are legions of aerospace companies in the Puget Sound region, which supply critical parts to the 787 Dreamliner’s manufacturer. Some outsourcing is absolutely necessary for Boeing to compete with Airbus. The concern is outsourcing critical components in a new airplane program, which is attempting to use technology never used in a commercial airliner. It’s ironic, li-ion batteries are at the center of the 787’s grounding — lithium batteries have been a concern for over a decade to the FAA, TSA & NTSB, even leading to bans & restrictions for passenger’s to bring on commercial flights. It’s almost hubris or a form of high-risk gambling, to “initially” rely so heavily on outside vendors [GS Yuasa, the Japanese firm making the li-ion & Thales, the French corporation making the batteries’ control systems] for producing an unproven, prototype system. 

While working as a Boeing employee in the 1990s, I recall an incident with a vendor supplying thousands of counterfeit aircraft quality fasteners made in China. Fortunately, the fiasco was caught early — but not before many hours and dollars were lost, going back to inspect wings on the production line, to remove and replace the defective fasteners. Unless solid

 metrics are emplaced to assure critical standards are met for each component, it’s only a matter of time before a failure will occur. Boeing has traditionally been an aerospace company, which “over engineers” it airplanes & errors on the side of safety. Hopefully the company has maintained & continues to practice these quality assurances. Outsourcing is practical both economically and politically for companies with international sells. It’s a successful strategy Boeing has used for many years; outsourcing has proven to provide incentives for foreign airline companies to buy Boeing aircraft, in order to support their own domestic aerospace industries.            The American auto manufacture Tesla, had similar “thermal runaway” issues when first using li-ion batteries to power its Roadster. Tesla Motors, benefited from its learning curve by switching to Lithium Iron Phosphate batteries, which run at cooler temperatures. The innovative auto manufacture also developed its own battery pack architecture, with proprietary liquid cooling system packs — for controlling battery cell temperatures within self-contained, metal lined enclosures.  The nontoxic, Tesla battery packs are manufactured domestically in Northern California. Perhaps Boeing should be considering manufacturing all critical systems in-house and domestically as Tesla has done.  

According to MIT Technology review’s – Kevin Bullis, who points to Boeing’s battery manufacture,  GS Yuasa’s web site ,  the 787 is using Lithium Cobalt Oxide batteries, which it also manufactures for the International Space Station. These batteries are categorized  as “high-energy storage capacity,” but are not considered resistant to heat as other battery chemistry. Another issue I’m speculating could contribute to the  787 li-ion batteries overheating relates to Boeing reintroduction of an [electrical compressing system] to provide higher pressurization for the cabin environment. This type of cabin pressurization system requires more electrical energy than standard systems, so could this be putting additional demands on the batteries? Part of the advantage to using more composite materials in the 787 was to reduce metal fatigue caused from the cabin pressurization cycles. The Dreamliner uses higher cabin pressure than most aircraft to make it more comfortable for passengers — however, li-ion battery manufactures specifically warns against over-pressurizing these batteries. Is the cabin pressure contributing to pushing the li-ion beyond their tolerance?

Whether or not the stated technical issues are of a real concern for the onboard battery system packs, can only be determined by thorough testing.

Again, it’s to early to know the exact extent of the problem with the 787’s battery systems. The issue will soon be isolated, as Boeing has long history of thoroughly testing and over-engineering its aircraft systems. One thing is certain, it’s rare for Boeing to experience a new aircraft being grounded simultaneously by  Japan’s transport ministry and by the FAA.

Ultimately,  A Bright Future Awaits The 787 Dreamliner

Gaining profitable fuel savings by developing a lighter, wide-body aircraft, combined with the fuel-efficient, GE or Rolls Royce engines, produces a major advance for airliner capabilities.  The tangible benefits in comfort, interior lighting and convenience  contribute to a remarkable passenger experience.  All the evolutionary, technical advances in the Boeing 787 Dreamliner, creates a remarkable new development  for commercial aviation. ~
