Evolutionary theory explains a wide range of biological phenomena. Proper understanding of evolutionary mechanisms such as natural selection is therefore an essential goal for biology education. Unfortunately, natural selection has time and again proven difficult to teach and learn, and students' resulting understanding is often characterized by…

First order knowledge and understanding, relating to the "stuff" of history, is, of course, absolutely fundamental to the development of children's historical knowledge and understanding. However, as Frances Blow shows, in a contribution to a series of articles exploring second order concepts in history published in Teaching History by…

This article reviews some recent research on the development of temporal cognition, with reference to Weist's (1989) account of the development of temporal understanding. Weist's distinction between two levels of temporal decentering is discussed, and empirical studies that may be interpreted as measuring temporal decentering are described. We…

Children with mental retardation have pronounced difficulties in using cognitive strategies and comprehending abstract concepts--among them, the concept of sequential time (Van-Handel, Swaab, De-Vries, & Jongmans, 2007). The perception of sequential time is generally tested by using scenarios presenting a continuum of actions. The goal of this…

Investigation of two- to four-year-olds' (N=20) understanding of temporal terms indicated that children were more likely to understand sentences using simple tasks, materials, and commands than more complicated sentences used in previous research. (Author/CB)

Investigated preschool children's understanding of temporal relationships in terms of their comprehension of sentences containing clauses linked by "before" and "after". Also evaluated was the relative importance of order of mention and main-subordinate relations strategies in children's interpretation of temporal order information. (Author/SDH)

Stories were constructed in which minor variations in content influenced the relationship existing between statements. The stories had four episodes, which were either logically related or independent. First and third graders could more accurately recall the structure of the logically organized episodes than that of the temporally listed episodes.…
