Fixing the STEM Problem by Asking the Right Questions-Don’t ask “Who, What, When, Where”; ask, “Why, and How?” Fixing the STEM Problem by Asking the Right Questions Essay by Allan C. Jones, President Emaginos Inc.- Engaging Every Child Through Customized Education Don’t ask “Who, What, When, Where”; ask, “Why, and How?” Education in the No Child Left Behind era is all about answering “who, what, when and where” (4W) questions. But the questions that really matter are why and how. In a European history class, students are asked, “Who fought at the battle of Hastings?”, “What armies fought in the battle?”, “When was it fought?”, and “Where is Hastings?”. I can still remember that the English fought the Normans led by William the Conqueror in 1066. I don’t remember where Hastings is, if I ever did know it. What I don’t know is why it was fought and how it affected history. In considering what I know and don’t know, it seems like the stuff I know doesn’t matter and the stuff I don’t know does matter. In general, what matters is the stuff you learn by asking why and how. The country’s leaders constantly complain about today’s students not learning enough about Science, Technology, Engineering and Math (STEM). STEM topics are boring if you focus on the 4W questions. But if you focus on “why and how” they come to life. Eli Whitney invented the cotton gin in the southern US before the civil war. Boring! Why did he invent it? How did it work. How was it powered? Why was it important? What recent inventions have had a similar impact on a nation’s economy? The last is a “What” question, but not a recall question. These are the interesting questions about the cotton gin – and they lead to a rich discussion of STEM. Let’s make the issue more contemporary. We tell children to use soap when they wash their hands. When they ask why they need the soap, the typical response is that soap gets the hands cleaner. This is usually where inquiry stops and authority takes over – just do it! But any healthy, curious child is thinking, “How does soap work?” The answer is, “Soap makes water wetter.” What does that mean? Soap breaks down the surface tension bonds between the water molecules. So the next obvious question is, “Why does that matter?” Because it allows the water to penetrate the dirt better to float it away. It also emulsified the grease molecules; allowing them to detach from the object and rinse away. I like to give the students another use for this piece of knowledge so I tell them that the next time they find a tick and are trying to kill it, the easiest way is to drop the tick into a cup of tap water. Initially, the tick will appear to float. (The little suckers are really hard to kill.) But ticks are not buoyant. They are not floating. They are standing on the surface tension. Add a drop of dishwashing liquid to the water and the tick will sink like a stone and drown. We were recently at yet another STEM meeting where the people were all excited about an excellent robotics activity that they were proposing to engage more girls and minorities in STEM. Robots are cool; and designing and playing with them can be engaging and instructional. But why go the expense of creating an artificial world for STEM learning? Students are surrounded by STEM every minute of their lives. Some questions they might enjoy answering could include: How do they get stone-washed denim to look that way? Do they really stone-wash it? Why do the tires on a mountain bike look so different from the tires on a racing bike? Do car and truck tires have the same or different tread designs? How do they decide what is the best tread design for different uses? How does changing the amount of air pressure affect the performance of the tires? When do you use low tire pressure and when do you use high pressure and why? Why does it get easier or harder to pedal a 12-speed bike when you shift the gears? How does the Derailleur work? How is the Derailleur different from a manual transmission on a car? Why does a manual transmission need a clutch and an automatic transmission does not? How does the clutch work? Why does a clutch burn out? How do iPods store all that music? What other options are available to store it? Why was the one they use chosen? What may be the next better storage mechanism? If you want to tie it into history, ask how people 200, 400, 600, 800, and 1,000 years ago did what we do routinely today. What did tires and treads look like at those different time periods? How were vehicles propelled? How was music stored and enjoyed? How does communications technology affect social unrest? Which technologies that were originally invented for military uses have become everyday household products? Did you know that microwave ovens came from radar technologies developed for guiding missiles? The list of fascinating STEM topics is endless. More importantly, they are an integral part of everybody’s world. All of the inventions and the underlying technologies were designed and built by engineers and technologists based on work by scientists and mathematicians. STEM is not some remote esoteric set of knowledge reserved for nerds. It’s a fascinating set of knowledge and skills that make up the world we live in. The 4W questions are only interesting if they are used in the context of why and how. Dropout prevention is another big issue in education. Because understanding why and how something happened are much more interesting than the 4W questions, students get more engaged in their learning when seeking answers to why and how. We need to get away from the model where the teacher asks the 4W questions and students answer them. We need to pose problems that require the students to determine what the questions are that they need answered in order to solve the problem. If you put the students in small ability-level based groups and frame the questions as problems to be solved, every student is actively engaged in learning. This student-centered learning environment also allows the teachers to work individually with every student and customize the learning for each of them. Going back to the battle of Hastings, knowing why and how it was fought and how the result of the battle impacted the subsequent history of England might be of use in looking at the US invasions of Afghanistan and Iraq. Can we learn any lessons from Viet Nam, Afghanistan, and Iraq that will enable us to make better decisions about the value of those strategies? We need to change the questions we ask our students and the way we pose them, not only in class, but also on assessments. There is an old axiom that applies; “You get what you pay for.” Since educational institutions get ‘paid’ for good assessments, they will structure the teaching and learning activities to produce what is assessed. So we need to do less assessing of who, what, when, and where; and start doing a better job of assessing students’ mastery of why and how. Data Infographic on STEM
