An Android-based application has been developed to provide color-blind and visually impaired students a multisensory perception of color change observed in a titration. The application records and converts the color information into beep sounds and vibration pulses, which are generated by the smartphone. It uses a range threshold of hue and…

A drug discovery project has been successfully implemented in a first-year general, organic, and biochemistry (GOB) health science course and second-year organic undergraduate chemistry course. This project allows students to apply the fundamental principles of chemistry and biology to a problem of medical significance, practice basic laboratory…

A three-tiered experiment for undergraduate Instrumental Analysis students is presented in which students characterize the solid-state thermal behavior of an active pharmaceutical ingredient (acetaminophen) and excipient (a-lactose hydrate) using differential scanning calorimetry, thermogravimetric analysis, and thermal microscopy. Students are…

Describes using a computer statistical software package called Minitab to model the sensitivity of several microbes to the disinfectant NaOCl (Clorox') using the Kirby-Bauer technique. Each group of students collects data from one microbe, conducts regression analyses, then chooses the best-fit model based on the highest r-values obtained.…

Describes the implementation of a new laboratory-based, interdisciplinary undergraduate course on linear dynamical systems. Focuses on geometrical methods and data visualization techniques. (Contains 20 references.) (Author/YDS)

This document presents a science experiment demonstrating the scientific method. The experiment consists of testing the fermentation capabilities of yeasts under different circumstances. The experiment is supported with computer software called BioLab which demonstrates yeast's response to different environments. (YDS)

Discussed is a method of measuring the coefficient of linear expansion of a solid. Getting many data points, using a computer program using the least square fit technique, and modifying the apparatus are described. (YP)

Reviews Apple computer science programs that are useful in a laboratory setting. Includes laboratory simulations, uses of Apple as a functioning lab instrument, and dissection programs. (ML)

The interfacing of a physical pendulum to an Apple IIe computer and the physic instruction associated with it are discussed. Laboratory procedures, software commands, and computations used in this lesson are described. (CW)

Introduces two hands-on experiences, related to rotational motion and moment of inertia. Discusses the experimental procedures and provides figure of apparatus. (YP)

Examines the effect of solar radiation on colored shingles. Describes the experimental procedure, results, and discussion. Presents a picture of the experimental arrangement and three graphs of data measured at different dates. (YP)

The purpose of this study is to investigate the effects of two laboratory environments for introductory chemistry on undergraduate students' inquiry skills. The two laboratory environments are embedded in the same lecture course. The standard laboratory curriculum and instruction are distinct from the curriculum explored in this study, the MORE…

Introduces microcomputer interfacing as a method for explaining and demonstrating various aspects of the concept of function. Provides three experiments with illustrations and typical computer graphic displays: pendulum motion, pendulum study using two pendulums, and heat absorption and radiation. (YP)

Reviews emerging applications of microcomputers and hypermedia to assessment. Use consists mainly of computerized test administration of multiple-choice tests drawn from item banks. Significant advantages are possible in several areas including immediate feedback to students, formative evaluation with remediation possibilities, and monitoring…

Introduced is a unique generation method of Fourier series requiring simple mathematical skills and using computer programs. Discusses Fourier synthesis by microcomputer, and Fourier analysis with simple equipment. Shown are a circuit diagram, computer programs, monitor displays and tables of data. (YP)
