Research and Innovation

Ask anyone to describe a great school and “commitment to continuous improvement” will be one of the qualities on their list. The immense success of The Country Day School graduates in their post-secondary programs and careers is clear evidence that we offer a superior educational experience.

At the same time, we are deeply committed to continually improving our approach. The School's commitment to research and innovation is a driving force in our ongoing professional growth and support of the parent community.

The Growing Mind

In providing education with balance, The Country Day School focuses on three key areas: challenging the student, developing the mind and strengthening the character. In reality, these three spheres of change and growth are inseparable: they overlap in a mutually supportive manner as they contribute to the development of the whole person.

There is a regular feature inside The Link – the CDS community magazine – entitled The Growing Mind, which may at first glance appear to belong to the “developing the mind” sphere. However, like anything to do with how our minds grow and change, the articles you will find there are focused on what Aristotle called eudaimonia – human flourishing. We flourish when our needs and interests are connected and in balance. The accessible and engaging articles on topics of current research in child growth and development you will find in The Growing Mind provide knowledge that can help you and your children thrive.

Pot and the Teenage Brain

Should we be worried about the effects of marijuana on developing minds? In a word, yes.

In adolescence through to the early 20s, the brain is undergoing a massive reorganization and reallocation of energy and resources. The areas associated with planning, prioritizing, problem-solving, emotional control, attention and risk assessment are under construction. This makes the brain especially vulnerable to outside influences and input.

At this sensitive time of development, the effects of alcohol and cannabis are significantly greater than later in life. Intoxication in any form disrupts the developmental process and can leave lasting effects. Recent research is uncovering the ways in which cannabis use among teens can lead to cognitive impairment, memory loss and susceptibility to mental illness.

The earlier a teen uses marijuana, the worse for the brain. Studies have shown negative impacts on mental processing, verbal learning, attention, memory, impulse control and motivation among 13-24 year olds.

Marijuana is not a harmless drug, as many teens argue. Our understanding of both brain science and the effects of THC on developing minds is growing, and the picture isn’t good. The opinion of the Harvard Medical School, for example, is that adolescents are uniquely susceptible to lasting damage from marijuana use, leading to both physical and neurological disorders.

It’s time to talk openly – at home and at school – about pot and the teenage brain.

balance is a state of living and learning that is achieved when the riches and challenges of life are experienced in healthy proportion.
