Describes an experiment where elementary students determine the optimum angle of inclination for the greatest amount of distance a marble will roll when accelerated down an inclined plane. (PR)

Presents performance assessments, written by a team of Wisconsin science teachers, designed to see if students know, have practiced, and are able to perform the skills associated with science problem solving. (JRH)

Presents the National Science Education Standards as an exceptionally well researched tool intended to assist teachers in curriculum development. Describes an activity that meets the standards and encourages students to work together. (JRH)

Specific ways in which lectures, laboratories, cooperative group learning, and examinations and grading can be used as part of a strategy to increase pharmacy student interest and involvement in basic science are outlined. The techniques focus on making the presentation of content at least as important as the content itself. (MSE)

An experiment accompanied by a series of writing exercises that engage students in activities that characterize scientific research is described. The exercise emphasizes experimental design and data analysis over technical manipulation. Possible issues for discussion and opportunities for collaboration and peer review are discussed. (KR)

Activities that use dandelions to show the phenomena of geotropism and autotropism are described. Directions for collecting the stalks and observing the gravitropic response are included. The topics of lag time and bending rates, autotropism, growth rate changes, presentation time, and gravity detection are discussed. (KR)

Explains the importance of introductory science courses and presents characteristics of exemplary courses. (PR)

Describes a simple and inexpensive, one-period activity to extract DNA to make the study of DNA less abstract. A microscope titration is used to determine when cells are ready for DNA extraction. (PR)

Describes an interesting field experiment examining the distribution and diversity of a single community using lichens and the animals living in them. Combining field experience and laboratory work reveals not only the biology of some unusual organisms, but also community ecology and diversity. (PR)

Proposes as a unifying theme for high school biology the question of "how chromosomes determine what we are." Describes a sequence of lessons in which students learn about proteins, enzymes, and amino acids. Includes three dry laboratory exercises to demonstrate the DNA sequences for sickle cell anemia and cystic fibrosis. (MDH)

Describes the use of Vee maps in helping students understand scientific investigations. (PR)

Describes an easy and inexpensive method of preparing experimental growth media that high school students can use for plant cloning investigations. (PR)

Reports on a questionnaire completed by 73 universities. Results indicate that laboratory instruction is part of almost all introductory biology classes. The majority (62%) of these institutions offer separate biology courses for majors and nonmajors. There is renewed interest in investigative types of laboratories. Most laboratory instruction…

Describes the use of a mystery substance, Oobleck, in a graduate-level course for secondary special-education teachers that considered ways to teach science. Principles of science instruction, teaching students with diverse disabilities, instructional congruence, student assessment, and modifications are addressed. (DB)

Analyzes undergraduate general-chemistry laboratory manuals (n=10) and identifies illustrative verbs representative of the types of cognitive skills given in Bloom's Taxonomy. Finds that, although the majority of the manuals are similar in their lack of promoting higher-order cognition, a few newer manuals possess the requisite activities for…
