Babai, Reuven; Sekal, Rachel; Stavy, Ruth – Journal of Science Education and Technology, 2010
This study investigated whether intuitive, naive conceptions of "living things" based on objects' mobility (movement = alive) persist into adolescence and affect 10th graders' accuracy of responses and reaction times during object classification. Most of the 58 students classified the test objects correctly as living/nonliving, yet they…
