A variety of methods for producing images and some of the tools available for image analysis are described. (BB)

Delineated are simple procedures by which evaluations can be performed of the concentrations of contaminants in chemical laboratories. (BB)

The feasibility of the laboratory production of copper metal from a readily available, naturally occurring mineral malachite utilizing techniques that are consistent with the time period of around 4000 B.C.E. is presented. The starting materials are inexpensive and convenient and the procedure involves no hazardous reagents and produces no…

Multistep syntheses are often important components of the undergraduate organic laboratory experience and a three-step synthesis of 5-(2-sulfhydrylethyl) salicylaldehyde was described. The experiment is useful as a special project for an advanced undergraduate organic chemistry laboratory course and offers opportunities for students to master a…

A PREPARATION LABORATORY WAS DESIGNED TO FAMILIARIZE STUDENTS IN ADVANCED MAMMALIAN PHYSIOLOGY WITH LABORATORY SKILLS AND TECHNIQUES AND THUS SHORTEN THE TIME THEY SPEND IN SETTING UP ACTUAL EXPERIMENTS. THE LABORATORY LASTS 30 MINUTES, IS FLEXIBLE AND SIMPLE OF OPERATION, AND DOES NOT REQUIRE A PROFESSOR'S PRESENCE. THE BASIC TRAINING UNIT IS THE…

Discusses reasons and need for experimental laboratories in engineering education. (SL)

Describes a technique for using lecture-laboratory facilities and faculty office facilities to provide students a site for intensive laboratory exercises. Provides a layout of the lecture-laboratory facilities and energy systems of the facilities. Presents an instructional example on the concept of the natural frequency of single-degree-of-freedom…

A pilot program in a public high school positions experienced student writing center tutors to become WAC liaisons who foster writing across the curriculum by raising questions, identifying needs, and providing support to their teachers with the goal of strengthening writing instruction school-wide. This article discusses the background and…

We have developed a tool called Secure WEb dEvelopment Teaching (SWEET) to introduce security concepts and practices for web application development. This tool provides introductory tutorials, teaching modules utilizing virtualized hands-on exercises, and project ideas in web application security. In addition, the tool provides pre-configured…

This study investigated the effect of blended learning on novices' understandings of the introductory programming. A quasi-experimental design with participants of preservice computer and instructional technologies teachers, one control group (CG, N =64) and one experimental group (EG, N=61) who received the course 11 weeks. While face-to-face…

In this article, the author talks about the college writing center, which is a place of political confrontation, where cultural issues involving dialect and values are probed, contested, and negotiated. He suggests a post-process approach to composition--one that ushers writers into a world of exploration and social engagement--one that transcends…

A SEQUENCE OF STEPS FOR ESTABLISHING LANGUAGE LABORATORIES ARE DELINEATED IN THIS REVISED PAPER. THE ORIGINAL PAPER WAS PRESENTED TO THE MODERN LANGUAGE ASSOCIATION CONFERENCE IN NEW YORK CITY ON THE "LANGUAGE LABORATORY IN HIGH SCHOOLS" (OCTOBER 1960). INCORPORATED IN THE REVISED PAPER ARE MANY SUGGESTIONS MADE BY THE CONFEREES,…

Radiocarbon dating has been central to the construction of archaeological chronologies for over 50 years. The archaeological, scientific and (increasingly) statistical methods for interpreting radiocarbon measurements to produce these chronologies have become ever more sophisticated. The accurate measurement of the radiocarbon content of an…
