This section of the product reference guide provides information for locating specific types of equipment used to analyze and control in-plant water and wastewater emissions. (CS)

This course presents the student with a performance approach to biology. Each technique is covered in standard lecture format and in guided, independent laboratories. Examinations and grading are competency-based and require knowledge of both the use and limitations of the techniques. (BB)

Included are discussions surrounding organics in water that were presented at the water quality technology conference in 1978. Information is also provided on up-to-date water quality lab practices for disease control, heavy metal detection, and sodium monitoring. (CS)

Describes some laboratory exercises using the mole crab, Emerita talpoida, as an experimental animal for the study of osmoregulation. (GA)

Two computer packages are described which augment laboratory experiments in which the effect of random variables on population processes can be explored. (MP)

Two papers are reported on, one dealing with a course on inorganic reaction mechanisms for college seniors, and the other on the set-up necessary to provide students with an automatic potentiometric titration facility. (BB)

The article corrects discrepancies in the literature on the founding of psychology laboratories in the United States before 1900. Previous reports omitted established laboratories and created disputes as to founders and dates of establishment. A review of literature and a list of laboratories are provided. (KC)

Elementary school teachers and volunteers turned a small room into a writing center, where elementary students can work on compositions with the encouragement of secondary school tutors. (SJL)

Falk School, the laboratory school for the University of Pittsburgh, has gradually developed a "personalized progress plan" that involves nongraded organization, multiple-age grouping, modified team teaching, and a carefully sequenced curriculum. (Author/MLF)

Describes a credit-bearing course at Brooklyn College which trains undergraduates to be peer-tutors in writing. (DD)

Deals with such matters as evaluation of the effect of peer tutoring, tutor training through counseling programs, and the effect of peer tutoring on retention in college. (DD)

Describes a simple conductivity apparatus for the determination of ionization and solubility product constants of various substances. The uses of the apparatus in determining the ionization constant of a weak monoprotic acid and in measuring the rate of diffusion of ions through a membrane are also presented. (HM)

An alternative development of the quadratic formula via paper squares and rectangles is presented. A physical model is constructed to demonstrate the constant term needed to complete the square. (MP)

Discusses a laboratory experiment in isotope production designed to help the students understand some of the concepts in elementary nuclear physics. (GA)

Describes an undergraduate experiment of research potential. The experiment cconsists of measuring the time of contact of a metal rod bouncing on a steel base as a function of the velocity of impact, length, diameter, and material of the rod. (GA)
