Most of these fully-developed library media activities are to be used in connection with specific curriculum units: art (paper marbling, grades 4-9); reading/language arts (national holiday customs, grades 1-6; Robin Hood, grades 4-5); science (zoo animals, grades K-2; the aurora borealis, grades 7-9; identifying and feeding birds (grades 2-3);…

Describes an inexpensive spectrum projector that makes high-dispersion, high-efficiency diffraction gratings using a holographic process. Discusses classroom applications such as transmission spectra, absorption spectra, reflection characteristics of materials, color mixing, florescence and phosphorescence, and break up spectral colors. (MDH)

Describes assignments in abstract writing as well-suited way to integrate writing into curriculum of large introductory geology courses. When students write abstracts on either assigned outside readings or special sections in their textbooks, they develop a concise writing style and polish their writing skills and also increase their understanding…

Authors describe a "writing intensive" physical geology course utilizing both formal and informal writing assignments. The formal assignment consists of a summary paper on four geological articles. A writing tutor provides feedback on drafts of the summaries. The informal writing assignment requires students to keep a journal related to laboratory…

Author describes her first-year seminar in history of geology where students are given writing assignments asking them to summarize, describe, explain, be convincing to reader. Students review their written work through frequent revision, peer review, collaborative writing assignments. Assignments require students to examine scientific principles…

Describes advantages and details of use of journal writing in introductory geology course. Entries include minimum of three one-page entries per week and count for 25 percent of course grade. Most students start with restatement of ideas presented in class; by end of the course, they are drawing original conclusions and applying ideas in new…

Describes a method of teaching geology and scientific writing to nonscience students that combines active integration of lecture, reading, and laboratory materials with field observations into a writing assignment on a real scientific problem. The writing assignment is completed in stages: a prospectus, a detailed report outline, a bibliography, a…

Describes an assignment in a paleontology course built around constructional morphology and the role of adaptation and exaptation in evolution. Students investigate the constructional morphology of a group of fossils that interests them. Findings are presented in an oral presentation and in a term paper. (27 references) (PR)

Describes an assignment in a graduate-level course in sedimentary-basin analysis that requires students to write a research-grant proposal. The assignment forces students to develop a topic suitable for original research. Each year 25 percent of the class turns these assignments into master's thesis projects and/or submits them as student grant…

Changes in college biology instruction in recent years reflect the changes in college instruction in general: information-dense textbooks, high-technology laboratory experiments, complex computer simulations, and easy exchange of data and ideas. Educators can now ask questions unthinkable by their classical forebears, and students can participate…

Analyzes problems with traditional teacher education, reviews the basic elements of the constructivist learning views, and discusses the advantages of a constructivist approach to science teacher education. (PR)

Explored how elementary school children (n=267) "think" about science vocabulary through an examination of the organizational schemes children employ with science words. A common core of vocabulary was developed from textbooks. Students grouped the words and gave the group a name. One result indicated students had appropriate conceptual…

The heat content of a food at a given temperature can be described by the thermodynamic property of enthalpy. Presents a method to construct a simple calorimeter for measuring the enthalpy changes of different foods during freezing. (MDH)

Seventh-grade students (n=397) were studied to determine the effect on immediate achievement and retention of a unit designed to promote the development of estimating skills involved in metric measuring. Identical metric instruction was used with the exception of activities in estimation for the treatment group. The treatment group retained…

This study sought to find out whether concept mapping reduces anxiety and thereby enhances achievement in biology. A total of 51 grade-10 students participated in the experiment. Findings indicate concept mapping is significantly more effective than traditional teaching in enhancing learning in biology and reducing student anxiety toward biology.…
