Whereas previous studies show that children are able to make meaning about evolutionary concepts within read-aloud contexts, little is known about how semiotic resources and interaction influence children's meaning making about evolution. This study investigates children's meaning making about evolutionary concepts during a modelling activity…

Many children learn about and experience animals in the everyday environment where they live and attend school. One way to obtain information about children's understanding of concepts or phenomena is by using their drawings in combination with written responses or interviews. This study assesses how much Slovenian students 10-15 years old (in…

Background information on the biology of aphids is supplied. Using this information in a wide variety of investigations, many involving equipment and techniques available in the school laboratory, can be carried out. An appendix lists possible projects. (Author)

The value of the genus Nematodius in teaching is not widely realized. Presented is a brief biological outline of the organism (including geographical distribution and reproductive cycle/behavior) and its use in student investigation of selective predation. (Author/JN)

Describes a study using two genera of aquatic insects that demonstrates how nonlethal falls in oxygen concentration affect the rate of surfacing of bottom-feeding Coroxidae and how this affects their survival by increasing their proneness to attacks by surface-feeding Notonectidae. (CS)

The carabid beetle (Notiophilus) preys readily on an easily-cultured collembolan in simple experimental conditions. Some features of this predator-prey system are outlined to emphasize its use in biology instruction. Experiments with another potential collembolan are described in the context of developing the method for more advanced studies.…

Reports on the implementation of an extracurricular course for fifth-grade students that focuses on the structure and function of animals. Students participate in direct observation of animals, watching videotapes, group discussion, and building kits and games. (DDR)

Describes a number of laboratory experiments using woodlice as experimental animals. Includes topics such as physiology of water relations, behavior, and rhythmic activity. (CS)
