Equipped with string and paper models, students are able to illustrate the processes of meiosis. (ZWH)

Describes numerous educational experiences in the state of Alaska. Includes travel options, descriptions of the different regions of Alaska, and tips on pretrip preparations. (ZWH)

Presents an activity that stresses the role of fungi and decomposers, highlights the rapidity by which they complete this process, and allows students to experiment with ways to control the rate of decomposition. (CCM)

Understanding antibody structure and function is difficult for many students. The rearrangement of constant and variable regions during antibody differentiation can be effectively simulated using a paper model. Describes a hands-on laboratory exercise which allows students to model antibody diversity using readily available resources. (PVD)

Presents exercises in which students can explore Type I and Type II errors using sporangia diameter measurements as a means of differentiating between two species. Examines the influence of sample size and significance level on the outcome of the analysis. (SAH)

Presents ways of discussing how to answer questions about common biological phenomena to introduce students to the rich explanatory power of selection theory to show the distinction between proximate and evolutionary answers and to discourage teleological thinking. (ASK)

Discusses the biodiversity crisis. Presents a simple invention to examine and photograph fish. (ASK)

Presents an activity that uses chenille stems, colored yarn, plastic straws, and ingenuity to make a low-cost manipulative kit for modeling mitosis and meiosis. (ASK)

Describes a method for teaching introductory biology courses using a microfiche reader to view tissue samples. Uses a microfiche reader as an overhead projector to further magnify and project biological images for students to observe in the classroom. (SAH)

Describes a method for teaching about DNA using looped cereals. Outlines the procedure and concept in detail. Presents several possible concepts that allow the instructor to choose what is the most appropriate for students. (SAH)

Describes the use of ethological observation methods in a study of student behavior for use in student or course assessment. Describes how a convenient, highly portable recording system designed for ethological observation can be used in educational settings. (Contains 12 references.) (ASK)

Surveys reveal that many in our society have an inadequate and inaccurate understanding of evolution (Alters & Alters, 2001). Much of this can be traced directly to popular misconceptions about the nature of science. This, in turn, can be linked to misrepresentation by those opposed to evolution, although inadequate or ineffective treatment by ill…

Describes the examination scheme developed to evaluate high school biology students using the BSCS project in Israel. The scheme consists of a practical examination and a written test. Since the scheme is relatively new, little research has been performed. (MA)

Provided is an activity for student-constructed dichotomous keys that requires nothing more than a pile of shoes. Examples and directions are given. (MA)

Explains the allium test in which roots are excised from onion bulblets grown in aqueous solutions of a test agent. Root tips are then isolated and stained with aceto-orcein, and chromosomal aberrations are microscopically observed. (Author/AIM)
