The Graphing Detective: An Exercise in Critical Reading, Experimental Design and Data Analysis.
Peer reviewed Peer reviewed
Pechenik, Jan A.; Tashiro, Jay Shiro – American Biology Teacher, 1992
This paper suggests an inexpensive way for encouraging discussions of experimental design and data interpretation for all grade levels. The discussion begins with the presentation of a graph or table from the scientific literature. Questions are then asked in six steps to promote an understanding of the information contained. (PR)

A Multidimensional Approach To Teaching Biology.
Peer reviewed Peer reviewed
Dimaculangan, Dwight D.; Mitchell, Paula L.; Rogers, William; Schmidt, John M.; Chism, Janice L.; Johnston, James W. – Journal of College Science Teaching, 2000
Describes a course design which tries to incorporate the investigative approach into the curriculum. Uses a project-oriented approach where students formulate questions and hypotheses and design experiments. Recommends the design for elementary school teachers who trained in science through traditional methods. (Contains 12 references.) (YDS)

Supporting Learning of Variable Control in a Computer-Based Biology Environment: Effects of Prompting College Students To Reflect on Their Own Thinking.
Peer reviewed Peer reviewed
Lin, Xiaodong; Lehman, James D. – Journal of Research in Science Teaching, 1999
Describes a study of college students who designed and conducted experiments involving control of variables after being assigned to one of four versions of a computer-based biology simulation learning environment. Finds that reason-justification prompts directed students' attention to understanding the employment of experimental design principles…

The Scientific Attitude.
Grinnell, Frederick – 1987
Science is many things to many people: a way of thinking and an activity of individuals in the laboratory; a highly structured institution that recruits, instructs, and regulates its members; and a sensitive, interactive, and integrated segment of modern culture and society. This book presents an introduction to these aspects of science from the…
