The study was designed to probe students' thinking about which numerical values can be assigned to algebraic letters. The data from students in Year 7 (n = 533), Year 8 (n = 377) and Year 9 (n = 172) was analysed using response patterns. The data confirmed that each year contained students with two misconceptions; "Different Letter means…

Objective: Describe beliefs about what makes foods healthful among low-income African American women. Methods: In one-on-one interviews, 28 low-income African American mothers viewed 30 pairs of familiar foods and explained which food in the pair was more healthful and why.

Findings suggest…

A partially unusual behaviour was found among 14 sophomore students of civil engineering who took a pre test for a free fall laboratory session, in the context of a general mechanics course. An analysis contemplating mathematics models and physics models consistency was made. In all cases, the students presented evidence favoring a correct free…

Background: The motivation for this work is built upon the premise that there is a need for research-based materials for design-based science instruction. In this paper, a small portion of our work investigating the impact of a LEGO[TM] engineering unit on fourth grade students' preconceptions and understanding of animals is presented. Purpose:…

The "Green Classroom" in the Botanical Garden of the University of Ulm is a learning forum outdoor school that is used by about 2500 school students annually.
