This manual presents item-by-item, step-by-step procedures for the student being trained as a technician in laboratory animal care. Statements are preceeded by a box for the student to check when he has read each statement. The first 16 lessons cover: orientation; identifying, handling, and determining the sex of rodents and rabbits, cats and…

This paper proposes a technique for using the digital computer in science instruction (grades 1-12) which may well obviate the constraints of unreasonable cost and demand for complex and extensive software. Computer Simulated Experiments require a short amount of time at the terminal during which the student collects realistic simulated data.…

Three articles in this newsletter describe investigative laboratory programs; two in marine or coastal biology (Hopkins Marine Station and the Bahamas field station of Earlham College), and the other a botany course at Colorado College. In all cases undergraduate students are expected to plan and conduct biological research, after being presented…

Observations and experiments with mice, developed and tested at the Pennsylvania Advancement School with underachieving boys in grades seven and eight, are described in this teachers' guide which includes copies of student worksheets for exercises needing them. In addition to lists of materials and procedural suggestions, ideas for guiding…

The relative effectiveness of "content-centered" and "process-centered" biology laboratory courses in a freshman general biology course was investigated by administering the Nelson Biology Test, Science Attitude Scale, EPS II (a problem solving test), and an Interest Inventory at the beginning and end of the one quarter course. Course examination…

Eleven tutorial-drill and four experiment-simulation computer assisted instruction (CAI) modules were designed and programmed for use on an IBM 1500 system. The modules were designed as supplementary study aids for an introductory chemistry course and were intended to assist students' achievement of specified behavioral objectives. After trial…

Detailed instructions for the construction of apparatus to detect qualitatively the production of carbon dioxide by respiring organisms are given, with notes on its use and comments on its advantages compared with traditional equipment. The chemistry section of the bulletin contains the results of tests of the efficiency of several laboratory…

General biology laboratory sections were assigned at random to four treatment groups. The four control sections used the normal laboratory manual and examined prepared slides with the laboratory microscope; four sections were assigned to each of the three experimental groups that used a linear programed manual with either 35 mm color…

The contributors to this volume take the position that the undergraduate biology laboratory should be a place where students conduct their own investigations rather than follow recipes supplied by the instructor. The first part of the collection discusses the need for this reform, with special consideration given to both majors and nonmajors. A…

Describes a system of laboratory instruction in which students attend laboratory when their schedules permit, and all laboratory sections, regardless of course, are overseen by one laboratory instructor. (MLH)

Simple soap bubbles can be used to have children make educationally valuable discoveries about how materials behave, what their properties are, and how they can be used or changed. (Author/BB)

This method uses the cathodic deposition of silver from a cyanide solution in a non-partition cell with stainless steel electrodes. (BB)

The method involves the dissolution of a small piece of metallic lithium in a small quantity of tertiary alcohol followed by addition to a mixture of the isocyanate and the tertiary alcohol in ether. This should be useful in organic chemistry laboratory courses for the identification of tertiary alcohols. (Author/BB)

The preparation of "p"-carboxystyrene from carboxybenzyl bromide in aqueous media is described. This is an example of a Wittig procedure that can be performed by students in one afternoon. (BB)

The Meerwein reaction is often omitted from undergraduate organic chemistry laboratory books. This experiment, the preparation of "o"-chlorocinnamic acid from "o"-chloroanaline, illustrates this section. (BB)
