Incorporating an evidence-based approach in STEM education using data collection and analysis strategies when learning about science concepts enhances primary students' discipline knowledge and cognitive development. This paper reports on learning activities that use the nature of viscosity and the power of informal statistical inference to build…

Previous studies (Case, 1985; Siegler, 1981) have shown that children under the age of 5 years have little understanding of balance scales when required to encode the influence of weight or distance from the fulcrum. More recently, however, Halford, Andrews, Dalton, Boag, and Zielinski (2002) noted that an understanding based on weight alone is…

Do we perceive correctly whether a 2-D object is balanced or unbalanced? What would be the cause of biased equilibrium judgments? In two psychometric studies, we varied independently the characteristics of the objects and the equilibrium states. First, we observed that observers were excessively sensitive to the eccentricity of the object top.…

A course is described that is designed to encourage exploration, conceptual invention, and expansion of an idea. Results are given that relate to curricular experimentation with chemistry. (SA)

A learning cycle consists of three phases: exploration; conceptual invention; and expansion of an idea. These phases parallel Piaget's functioning model of assimilation, disequilibrium and accommodation, and organization respectively. The learning cycle perceives students as actors rather than reactors to the environment. Inherent in that…

Conceptual change teaching is an instructional method that helps students modify, extend, or exchange their alternative conceptions for the appropriate scientific conceptions. Provides activities and a diagnostic test to apply the method to the concepts of heat and temperature. (MDH)

Discusses the advantages of using discrepant events in elementary school science classrooms in terms of motivation and problem solving skills. Describes the materials, procedures, and reasons behind five discrepant activities. (YP)

Science and social studies have much to offer to all learners--including those with disabilities. However, instruction in these subjects has often been overlooked in the quest to better understand and improve leaning in English/language arts and mathematics. As we demonstrate in this paper, science and social studies help students attain skills,…

The purpose of this study was to document and analyze teachers' and students' activities during physics practicals in order to gain critical insights into why students did not acquire the expected practical skills and how theory and practice interacted in the context of teaching for the practical examination in physics. The study involves three…
