  1. Cognitive Dev. in Adolescence Des. Cognitiva en la Adolescencia

  2. Pendulum Experiment • Piaget showed children/adolescents a pendulum. • Asked “What determines the speed”? Heaviness, weight, length of string?” • Concrete operational: random approaches (alter more than 1 variable at a time); cannot explain the correct answer (i.e. – length of string) • Formal operational: will change one variable at a time to get to the right answer; first, tests weight; then length of string • http://www.youtube.com/watch?v=E-6NDrpzGAE • 5 min 37 sec
