Described is a study of 147 students that indicated a high proportion of students did not understand the concept of limiting factors. Textbook presentations that create problems are discussed. Strategies which may be more effective in teaching the concept are suggested. (CW)

Discusses the emergence of the biology curriculum which replaced physiology, zoology, and botany in high school science courses and supplanted an early form of general science known as natural history. (RT)

Describes a teaching exercise used to demonstrate the importance of context in studying the ecology of animals. Uses the game of chess to examine the relationship between information and context and as an analogy with ecology. Discusses procedures, examples of results, and insights gained from this activity. (CW)
