In this study, the effectiveness of concept cartoons in diagnosing and overcoming students' misconceptions related to photosynthesis subject was examined. Firstly, the literature has been thoroughly examined and misconceptions about photosynthesis subject have been listed and then grouped. Concept cartoons related to these groups have been…

This book of activities is designed to supplement a child's outdoor experiences and to encourage children to take a closer look at nature by creating temporary mini-habitats at home or in school. An introduction explains to students the concept of habitat and the responsibilities of keeping a mini-habitat. The remainder of the book contains…

This booklet, one of six in the Living Things Science series, presents activities about cells which address basic "Benchmarks" suggested by the American Association for the Advancement of Science for the Living Environment for grades 3-5. Contents include background information, vocabulary (in English and Spanish), materials, procedures,…

This booklet, one of six in the Living Things Science series, presents activities about diversity and classification of living things which address basic "Benchmarks" suggested by the American Association for the Advancement of Science for the Living Environment for grades 3-5. Contents include background information, vocabulary (in…

This guide contains indoor and outdoor gardening activities for children. The activities teach children how plants live and grow; how the weather, temperature, and seasons affect all living things; how living things come out of seeds and soil; how the birds, earthworms, bees, and toads help in the garden; and how the whole environment works…

The rationale of audio-tutorial instruction is discussed, and the history and development of the audio-tutorial botany program at Purdue University is described. Audio-tutorial programs in geology at eleven colleges and one school are described, illustrating several ways in which programs have been developed and integrated into courses. Programs…

A complete audio-tutorial course in sophomore-level plant morphology was prepared, using an existing textbook and laboratory manual. Audio scripts, behavioral objectives and unit quizzes were written by the research participants. A pilot study was completed and needed revisions made. Preliminary testing was begun, but the number of students…

The growth and study of lower fungi, especially Oomycetes and Zygomycetes, in the biology classroom are described. (BB)

Describes the historical uses of popular plant roots such as mandrake, ginseng, chicory, belladonna, and blood root. Besides the text, information is organized into a table presenting use, application, and constituents. (MA)

Proposes that caution be used against generalities and improper terminology in the description of structure and function relationships. (CP)

Describes how and why plant habitats naturally change. Focuses on changing flora of New York's Pine Bush dune flats and the McLean Bog. (NEC)

Related history and laboratory work which lead to isolation of oligosaccharins, a new class of regulatory molecules found in plant cell walls. These substances function in growth, development, reproduction, and defense. Mixtures of oligosaccharins and other hormones can stimulate growth of an undifferentiated callus, roots, vegetative…

Describes methods for isolating, purifying, and analyzing plant hormones (molecules involved in plant growth regulation and development). The presentation reflects the historical development of analyses, beginning with bioassays and ending with novel immunochemical assays. (JN)
