The making of microscope devices using inexpensive or recovered materials is demonstrated. Examples of images illustrating the performance of such devices are presented. As a project at the undergraduate level, the task is effective in acquiring familiarity with optical imaging concepts and their practical implementation in the laboratory.…

This paper addresses methodological issues arising from an experimental study of North Carolina's Early College High School Initiative, a four-year longitudinal experimental study funded by Institute for Education Sciences. North Carolina implemented the Early College High School (ECHS) Initiative in response to low high school graduation rates.…

Today's language classroom is vastly different from that of the mid- to late 20th century. The study is a meta-analysis of recent research which provided the means to identify current and emerging trends in the field. Informed by this research, some identified trends that are shaping the 21st century language classroom are outdated practices such…

Physical World is a one-semester course designed for elementary education majors, that integrates earth science, astronomy, and physics. The course is part of a four-course set that explores science concepts, processes, and skills, along with the nature of scientific practice, that are included in state and national standards for elementary school…

A unique approach was planned and implemented for undergraduate dental students that would reinforce the principles of removable partial denture (RPD) design. 162 students were grouped according to their year of dental studies (66 second-year students and 96 third-year students) within the Discipline of Prosthodontics at the Faculty of Dentistry,…

Courses in Computer Architecture and Organization are regularly included in Computer Engineering curricula. These courses are usually organized in such a way that students obtain not only a purely theoretical experience, but also a practical understanding of the topics lectured. This practical work is usually done in a laboratory using simulators…

Reports on Project SEED (Summer Educational Experience for the Disadvantaged) a project in which high school students from low-income families work in summer jobs in a variety of academic, industrial, and government research labs. The program introduces the students to career possibilities in chemistry and to the advantages of higher education.…

A language resources center includes a large audio cassette library along with a standard dial access laboratory system. Students may check out and use cassette tapes to listen and record, and teachers may check student recordings on a flexible schedule. Tapes are also synchronized with slide series for audiovisual presentations. (CHK)

As an illustration of an attempt at dealing with the problem of time-sharing small computers for laboratory control resulting from conflicts between real-time responsiveness needs and the matter of priorities and administration of the system as a whole, a description is provided of a time-shared system that is used to control and service multiple…

A laboratory experiment, based on a simple electric circuit that can be used to demonstrate the existence of real-world "related rates" problems, is outlined and an equation for voltage across the capacitor terminals during discharge is derived. The necessary materials, setup methods, and experimental problems are described. A student laboratory…

Developed to increase student and teacher awareness of safe laboratory conditions, this guide provides information and suggestions for maintaining a safe laboratory environment. Section 1 contains a listing of potentially hazardous chemicals commonly used in secondary school science classes and section 2 lists potentially hazardous chemicals…

To demonstrate that properly designed laboratory instruction does provide affective and higher order learning benefits, an experiment was carried out in two replications. The subjects were 80 students enrolled in General Microbiology at Wallace Community College, Alabama. Students were randomly assigned to experimental and control groups. The…

A listing of business classroom and laboratory equipment, to be considered representative rather than exhaustive, was compiled from information submitted by over 100 manufacturers on their products, including office appliances, furniture, and audiovisual aids. Price is indicated for the majority of items. (AJ)

Discusses the use of rubberbands, an empty wooden thread spool, two wooden matches, a wax washer, and a small nail to conduct an experiment or demonstration in powerplant design. Detailed procedures and suggested activities are included. (CC)

This publication is the third product of the project to significantly update and reorder the Science Syllabus for Middle and Junior High Schools of the State of New York, Department of Education. The understandings, questions, and learning activities in the publication have been enhanced by the inclusion and referencing of program objectives,…
