Evaluated was achievement by college freshman students in a chemistry laboratory course. Twenty-eight sections, a total of 292 students, were grouped into six sections with written direction in a structured laboratory experiment schedule, six sections with verbal direction in a structured schedule, and sixteen sections with an unstructured…

The Pennsylvania Advancement School operates as a laboratory for stimulating positive change in the educational community through its programs for urban students and teachers. Sixth to eighth grade boys performing below potential in Philadelphia schools are brought to the school to participate in instructional projects during at least one 14-week…

A simple but physically realistic model is shown to be adequate for estimating long-term average pollutant concentrations due to area sources in cities. In this model, the surface concentration is directly proportional to the local area source strength and inversely proportional to the wind speed. The model performs nearly as well as much more…

This book is intended as a guide for teachers who want a practical aid to individualization of learning. Its primary focus is on the specific steps needed to implement learning centers. This includes planning, scheduling, teacher-student relationships, student evaluation, and finding and using materials. The book is divided into four sections.…

Milligan College instituted an off-campus laboratory program for its student teachers. A team of classroom teachers works with the prospective teachers. At the sophomore level some observation and teaching is done by students who are then evaluated. During the junior level a student is assigned one child to aid in reading abilities for 5 weeks.…

Describes an experiment in which atomic diffusion in a solid is accompanied by a color change. (MLH)

Introduced is a method for estimating carbon-13 nuclear magnetic resonance (NMR) shifts. The method is brief and simple so that students can use it with ease. (RH)

An instructional robotics laboratory that is unique in the United States was created in 1984 at the University of New Mexico. Descriptions of the laboratory, course work offered, student projects, and other areas are provided. (JN)

Describes construction of an Armatron robot arm controlled by a Timex Sinclair 1000 computer, a project suitable as an industrial arts laboratory activity. (SK)

Monoclonal antibodies have provided an exciting addition to the "armory" of the molecular biologist and immunologist. This article discusses briefly the concept of, techniques available for, production of, and possible uses of monoclonal antibodies. (Author)

Conventional sellotape techniques for fungal mounting produce interference patterns when using Normarsky microscopy. A technique is described which overcomes this problem and produces a permanent mount with a completely clear background. (Author/JN)

Failure is frequently the end point of laboratory exercises in physiological psychology that involve stereotaxic surgery by inexperienced students. Lab instructors should caution students to pursue the potential location of misplaced brain lesions using a variety of simple behavioral tests and the Thompson stereotaxic atlas. (Author/RM)

The mirror drawing apparatus (MDA) is a valuable experiential learning tool with specific applications in general psychology, educational psychology, and recruiting. Specific applications are described. (Author/RM)

A microcomputer-based Universal Laboratory Training and Research Aid (ULTRA) provides meaningful laboratory access to blind students and students with upper limb disabilities. Using ULTRA, blind students can perform chemical experiments independently. (CL)

We determined that a Center for Business Communication (CBC) had a significant impact on helping college of business students improve as writers. The variables were labeled college grade levels, male vis-a-vis female, frequency of visits, reasons for visits, pre-diagnostics vis-a-vis post-diagnostics, and declared majors; they were tested for…
