Our research aims to identify domain-specific similarities and differences of externalized cognitive structures. Cognitive structure, also known as knowledge structure or structural knowledge, is conceived as the manner in which an individual organizes the relationships of concepts in memory. By diagnosing these structures precisely, even…

Explores children's understandings of insect life cycles through pre- and postinstructional interviews, analysis of children's journal entries, and talk that occurred throughout the instructional unit. Contains 38 references. (DDR)

Reports research that examines children's models of seed. Explores the conceptions held by children (N=75) of germination and seed formation. Concludes that children hold a restricted meaning for the term 'seed'. (DDR)

In order to name an animal they see, children must use their existing mental models to provide the animal with a name. In this study, pupils between the ages of 4 and 14 are presented with preserved specimens of 6 different animals and asked a series of questions about them. The results indicate that pupils of all ages mainly recognize and use…

Argues that there are many kinds of understanding and many ways to reach these different understandings. Suggests that this is the reason why articulating general rules that can consistently lead to understanding is difficult. Discusses the relationship between brain structure and learning. (DDR)

Describes how Mexican-American language-minority students construct biology concept meanings based on extant linguistic skills. Provides an instructional activity that engages students in constructing meanings through mediational means. Contains 35 references. (DDR)

Reports on a project in which children develop instructional technology skills while learning a great deal of science. Explains how children construct a multimedia presentation on the topic of invertebrates. (DDR)

Describes a study that examined changes in the structural complexity of knowledge held by two groups of introductory college-level biology students (N=68, N=93). The subjects constructed concept maps at four-week intervals throughout the instructional term. Contains 49 references. (DDR)

The concept maps contained in this book (for grades 7-12) span 35 topics in life science. Topics were chosen using the National Science Education Standards as a guide. The practice exercise in concept mapping is included to give students an idea of what the tasks ahead will be in content rich maps. Two levels of concept maps are included for each…

Points out that college freshmen expect major changes in the academic environment as they move from secondary school. Recommends that faculty use this opportunity to show students how to think for themselves. (DDR)
