This PowerPoint is a useful tool to show your students the differences between Medieval art and Renaissance art by comparing paintings of "Madonna and Child." Students can evaluate the quality of technique developed over time, and notice how artists paid closer attention to anatomy. The PowerPoint also introduces perspective, arguably the most important technique discovered during the Renaissance. This makes use of the theory of Constructionism by having students build upon prior knowledge.
Students can use this simple exercise to practice one-point perspective, and see for themselves how perspective is created through a step-by-step project. Piaget theorizes that a step-by-step progress is extremely beneficial to learning, to create building blocks for students.
If you have gifted students, or extra time, have students lie on the ground and tape a paper to the bottom of their desk. They will then draw upon the paper as if they are Michelangelo painting the Sistene Chapel.
For further insight on the use of Piagetian and Constructionism theories, feel free to use this lesson plan provided.
