Young children who come up with explanations while learning are able to connect new ideas with prior cause-and-effect knowledge, a new study has revealed.
Cristine Legare, associate professor of psychology at University of Texas at Austin and lead author of the study, said that the way children gathered evidence through exploration and understood it through explanation provided insights into the development of scientific reasoning and this strategy could help young children harness their potential for scientific reasoning and improve their critical thinking skills.
In order to examine the potential benefits of explanation-based learning, Legare and her collaborator, Tania Lombrozo of the University of California at Berkeley, presented 182 preschoolers from age 3 to 6 with a mechanical toy composed of colorful, interlocking gears with a crank on one end and a propeller on the other.
Legare examined that when teachers and parents asked children to explain "why" and "how," they gave them an opportunity to think like scientists and this approach was effective in and outside the classroom.
The study concluded that, the explainers across all age groups outperformed other children to understand the cause-and-effect operations of the toy and they were also better at rebuilding the toy and to transfer that new knowledge to other learning tasks.
The study has been published in the Journal of Experimental Child Psychology.
