   * **Constructivism** - Piaget was a constructivist theorist suggesting children **construct** their knowledge through **interaction of their biological predispositions with their experience**. **Active self-discovery** of rules underlying current concepts and outcomes is the key to learning.
+These assumptions made Piaget believe that learning using tutoring procedures was ineffective, and that constructive learning should provide much better results. Still, research has soon shown that both assumptions were generally incorrect.

 ===== Criticism =====
-A common criticism of Piaget's theory lies on the fact that nor him or coworkers didn't leave an instrument for diagnosing child's current stage of cognitive development. Still, as a border between preoperational period and operational period Piaget suggested **conservation experiments**. For example, two equal glasses filled with liquid are presented to a child, after which liquid out of one glass is poured into a third, more narrow glass. The child is then asked which glass holds more liquid. Only a child in the concrete- or formal-operational  period should realize both glasses hold equal amount of liquid. According to Piaget's theory, these stage differences cannot be overcome using any kind of training.

The child's **ability to learn** (at least for conservation concepts) **is not so strictly defined by his current stage of cognitive development** in accordance with Piaget's theory.
