Singapore Math has gained in popularity in the United States in recent years. Numerous schools, both private and public, have adopted it with varying degrees of intensity and success. But where did Singapore Math come from, and what makes it different?
Ironically, Singapore Math has its roots in the United States. Born October 1, 1915, American psychologist Jerome Bruner has spent a lifetime dedicated to understanding how humans perceive and learn. He graduated from Duke University in 1937, and obtained a PhD in pyschology from Harvard in 1941.
A pioneer of modern psychology, his work on human perception and sensation was important in establishing the concepts of cognitive psychology. Following his work on perception and sensation, he turned his attention to learning and developmental psychology. His work there led to a framework of how learning takes place that can be applied to various situations. The framework is broken down into 3 stages, also known as the 3-step learning process.
Enactive – Sometimes called the ‘concrete’ stage, the enactive stage involves interactions with the physical world and objects — how they fit together or come apart, how they can be grouped, etc.
Iconic – The iconic or pictorial stage is when learning occurs by looking at pictures or models.
Symbolic – The symbolic or abstract stage is where learning can take place in abstract terms.
Singapore Math aims to utilize these three stages, progressing deliberately through each. In the enactive stage, students are taught by using physical objects in the classroom — paper clips, crayons, or other objects that they can pick up, pile up, and shift around. Subtraction, then, would be taking a few crayons from a pile, and figuring out how many are left. This isn’t described as subtraction, so much as it is a demonstration of play.
In the iconic stage, Singapore Math has students drawing pictures — usually bar models — to describe ratios and simple equations. The emphasis is on visualizing what happens
during the mathematical exercise. At this point students still aren’t thinking in terms of algorithms, equations, or even numbers.
In the symbolic stage, students start using numbers and equations. With concrete and iconic bases, the idea is that the symbolic stage will be more easily understood.
The application of Singapore Math in the United States has mad mixed results. Unless schools utilize the curriculum completely, it can fail. Also, since most Americans learned math a different way, parents may have difficulty helping their children with Singapore Math homework, instinctively teaching algorithms (stage 3) when the children are counting paperclips (stage 1). Still, the concrete applications like this of cognitive psychology to learning are exciting steps toward improving education.
