This research inquired elementary school students' learning effect by using quasi-experiment, expositive-teaching and experiential-teaching methods for nanotechnology in the microcosmic world. By utilized the pretest "Nanotechnology Situational Questionnaire (NSQ)",…

Describes science-related questions asked by young students aged 4-6. Discusses appropriate responses to typical science questions. (WRM)

Three groups of sixth, eighth, and tenth graders took pre- and posttests on a Piagetian problem and a problem that evoked a misconception. Two intervention groups engaged in group transactions intended to create inter- and intrapersonal conflicts or took a multiple-choice test.

Reports on an investigation of young children's (n=15) spontaneously constructed or naive understanding of the particulate nature of matter to any formal instruction in the domain. Speculates that children first develop local frameworks particular to different classes of substances, then slowly expand those frameworks to include a wide range of…

This study tested the effectiveness of having fifth-grade students generate their own examples of selected concepts on energy. Hypotheses were that subjects would perform better on sections of a test related to definitions and recognition of exemplars of the concepts for which they found their own examples than on sections related to comparible…

Two studies examined the construction of children's beliefs about projectile motion of a ball rolled off a table. Describes the concepts used by children, analyzes their use as a function of age, and gives a naturalistic description of their use. Results indicate that appropriate instruction can remediate misconceptions. (MDH)
