What you learn in Theory:
Newton's Law of Cooling states that the rate of change of the temperature of an object is proportional to the difference between its own temperature and the ambient temperature (i.e. the temperature of its surroundings).
What you learn in Practice:
The rate of heat loss of a body is proportional to the difference in temperatures between the body and its surroundings.
