CHEMISTRY: THREE REASON WHY IT TROUBLES STUDENTS.
“A HIGHLY SYMBOLIC AND ABSTRACT SUBJECT”
For many secondary school students, chemistry is seen as a complex and abstract subject. Indeed, understanding chemistry relies on picturing the invisible such as the interaction of particles before being able to accurately describe properties of substances.
At PMC, we combine a concrete-pictorial-abstract method with a deductive thinking approach to support and scaffold students’ learning. For example, in the topic of chemical bonding & properties, schools often task students to memorise and regurgitate keywords. Here, we support our students’ understanding of big ideas such as the requirements for electrical conductivity – having charged particles that can move! Scaffolding students’ knowledge with models and animation, PMC students are able to accurately deduce the electrical conductivity of any substance given to them.
