Challenging the Status Quo in STEM Education – Adetola Salau

How do we change teaching methods to ensure that students have greater understanding of STEM subjects and improve their skills?

It’s no surprise to state that little has changed in how we teach STEM in Nigeria in the last century. As a result, it seems, Nigerian students have been left behind, falling further behind inscience and math literacy.

There have been futile national reform efforts to improve things. The issue with them has been a lot of inconsistency and lack of a cohesive effort as changes in teaching practices have been minimal.

In our reform efforts in working with schools, I’ve aided some teachers to implement modifications –  with some success. The crux of the matter is more often than not; the changes aren’t as substantive as they should be. They don’t get at the heart of the matter: What does it truly mean to teach and learn STEM?

Traditional approaches to teaching STEM

The way we have been teaching STEM normally follows this pattern: The teacher demonstrates a set of steps that can be used to solve a definite kind of problem. Then the same type of problem is then introduced for the class to solve together. Afterwards, the students get a number of exercises to practice on their own.

A ready example that springs to mind is when students are taught about the area of shapes, we give them a set of formulas. They then put numbers into the correct formula and calculatesolutions. Harder questions might give the students the area and have them work backwards to find a missing dimension. They are then given a different set of formulas each day: perhaps squares and rectangles one day, triangles the next.

What happens is that they are learning to follow a rote process to arrive at a solution. This is how we have been teaching them without wondering if it is right or wrong.

It does make sense to majority of the students and it does seem satisfying.

The irony is teaching STEM this way does hinder learning; children for the most part become dependent on tricks and rules that aren’t always correct in all situations, which makes it harder to adapt their knowledge to new situations.

A perfect example of this is how we teach distribution through the traditional methods of teaching, children learn that they should distribute a number by multiplying across parentheses (brackets) and will practice doing so with numerous examples.

When they get to solving equations, they have issues realizing that it’s not always required. Look at the equation 3(x + 5) = 30. We have mostly programmed them to multiply the 3 across the parentheses to make 3x + 15 = 30. They could have easily divided both sides by 3 to make x + 5 = 10,it’s hard for them to break away and utilize this different method – although both ways are equally correct.

This is what we strive for at our foundation, transforming education to drive more conceptual understanding. Concepts are about the meaning and relationships behind ideas. It’s more than just utilizing procedures (like calculating the area of a triangle) but the deeper meaning behind the procedure (what is area? why is it relevant?).

We ought to move away from rote memorization as there are less and less need for storing information these days. Most formulas are easily retrievable online. Our focus should be the transfer of knowledge to various situations rapidly to solve problems.

 When I taught area to my students, I carried out project based learning exercises that emphasized what area meant and how areas of different shapes are related. This understanding correlated to their grasp of what volume was.

It is harder and longer in the view of most teachers to convey STEM concepts but when you take a long term view in teaching, you get why it’s absolutely critical we do this. Our students must think!

Research has proven that teaching conceptually enables students to do better on achievement tests— hence our emphasis on STEM education which has Project Based learning as its cornerstone.

Renowned education expert Pasi Sahlberg states it well:

We prepare children to learn how to learn, not how to take a test.
