Presents an embryology laboratory observing the development of Ginkgo biloba's embryos into trees. Explains the methodology for the lab and discusses research questions. (YDS)

Advances six practical suggestions in transpiration whereby teachers can support students in their struggle to put their thoughts, especially everyday mental models, in accordance with classroom experimental evidence. Discusses the wider implications for how to teach about living things and how to view the status of analogies in science generally.…

U.S. colleges of agriculture and technology transfer offices have historically been in conflict over the management of plant varieties. A simple model that would allow these competing systems to become integrated uses a decision tree. (Author/JOW)

This paper reports on a study that investigated the alternative conceptions of students in a biology and geology teacher education course regarding plant nutrition. Data were collected from first year and final year students using a questionnaire that had both multiple choice and descriptive items. Findings indicate common features related to the…

Describes a project that enables students to emulate a scientist in the classroom setting through collaboration on research projects, use of research literature, and communication with scientific peers. Student groups focus on investigations of the cellular and molecular aspects of a disease. (DDR)

Describes The Flora of North America, the first comprehensive description of all plants growing spontaneously in North America. Discusses online resources, the publication as an educational resource, the published volumes, and scientific and planning applications. (JRH)

Introduces a brine shrimp assay to demonstrate the effects of the biological activity of herbal remedies. Describes two protocols, one using aqueous extracts and the other using methanol extracts. (Contains 21 references.) (YDS)

Examined 10 introductory college-level, general biology survey textbooks for the coverage of algae to assess the efficacy of coverage. Describes a proposal of seven kingdoms and discusses the disposition of algae among five of these kingdoms. Contends that textbooks should highlight the concept of algae across the five kingdoms. Contains 59…

Discusses botanical illustrations, including herbals, printed books, flowers, British botany, printing advances, and art and science. (23 references) (MKR)

Points out the usefulness of drawing for a biologist, how biologists spend time on it, and contrasts how teachers do not spent any time on drawing in biology education. Recommends starting drawing with plants because they are stationary. Provides drawing exercises and explains how to draw with different techniques. (Contains 12 references.) (YDS)

Presents a field exercise illustrating the ecological requirements of a group of organisms and testing the common hypothesis "moss only grows on the north side of trees". Describes the protocol. (YDS)

Describes the topics and teaching strategies employed in an Issues in Biology course. Discusses flowers, plant breeding, potatoes and tomatoes, the chocolate tree, weeds, Arabidopis, gene transfers, and plant genes/human genes. Contains 22 references. (JRH)

Provides an activity that focuses on the color changes of leaves and reinforces lectures in ecology, plant physiology, and the scientific method. (ASK)

This book provides laboratory experiments to enhance any food science/botany curriculum. Chapter 1, "Introduction," presents a survey of the techniques used in plant biotechnology laboratory procedures. Chapter 2, "Micronutrition," discusses media and nutritional requirements for tissue culture studies. Chapter 3, "Sterile Seeds," focuses on the…

Describes two investigative labs that use live plants to illustrate important biological principles, include quantitative analysis, and require very little equipment. Each lab is adaptable to a variety of class sizes, course contents, and student backgrounds. Topics include the evolution of flower size in Mimulus and pollination of Brassicas. (DDR)
