Examines a solubility laboratory experiment using silver acetate and spectrophotometers for an Advanced Placement chemistry course. Covers experimental procedure, analysis of saturated solutions, and a discussion of chemistry involved. Includes an absorbance curve for silver ions and solution preparation suggestions. (ML)

Twenty science experiments are presented. Topics include recombinant DNA, physiology, nucleophiles, reactivity series, molar volume of gases, spreadsheets in chemistry, hydrogen bonding, composite materials, radioactive decay, magnetism, speed, charged particles, compression waves, heat transfer, Ursa Major, balloons, current, and expansion of…

Describes some adaptations made in a university physics laboratory course to accommodate a student with total visual impairment. (WRM)

This multiple case study examined the coauthorship process in research laboratories of different university departments. The study focused on two cases comprising five writing teams, one in biochemistry and microbiology and four in earth and ocean sciences. The role of the research supervisor, the role of the student (graduate and postgraduate),…

Classroom discussion of scientific articles can be an effective means of teaching scientific principles and methodology to both undergraduate and graduate science students. The availability of classic papers from the American Physiological Society Legacy Project has made it possible to access articles dating back to the early portions of the 20th…

The purpose of this study was to investigate the possible responses to anomalous data obtained from experiments that are repeatable by carrying out additional or alternative experiments in the laboratory. Based on an analysis of responses from scientists to anomalous data taken from identification experiments on the Vinland Map, it was assumed…

Functional brain imaging has overshadowed traditional lesion studies in becoming the dominant approach to the study of brain-behavior relationships. The proponents of functional imaging studies frequently argue that this approach provides an advantage over lesion studies by observing normal brain activity in vivo without the disruptive effects of…

Since 1999, students who reside in campus housing at the University of South Carolina have completed an annual residence hall computer and technology survey. More than 2,800 students completed surveys during the fall 2001 semester, and approximately 1,800 completed the survey in 2006. The survey has changed over the years to include questions…

Purpose: Drawing from findings of a case study of inter-organisational collaboration, this paper aims to employ organisational theory to examine the potential learning that opens between educational organisations. The focus is discursive practices. Two questions guide the analysis. What (unique) practices are implicated in the "knotworking" of…

In the ever-expanding realm of science, educators struggle to share new discoveries and techniques with their students. Keeping abreast of recent advances can be daunting, even for the most motivated teacher. Fortunately, the National Science Foundation's (NSF) Research Experiences for Teachers (RET) program helps educators keep up with the…

Undergraduates with little training on molecular biology may find the technical level of the typical introductory restriction laboratory too challenging and have problems with mastering the underlying concepts and processes. "Blackboard electrophoresis" is an active learning exercise, which focuses student attention on the sequences and principles…

Over the past decade, increasing numbers of institutions have reported using undergraduate students as instructors in science and technology courses. Undergraduates are most commonly used as assistants to graduate students, staff, or faculty who are the primary instructors for the course or lab/recitation section. In some cases, however,…

Students should enjoy their laboratory classes and for this purpose a project-based activity is added to a conventional physical chemistry laboratory. Students were given project work instead of conventional experiment and then they had to make progress in the project according to instructions and then carry out experiments related to the project.

In this exercise the US Standard Atmosphere is used as "data" that a student is asked to model by deriving equations to reproduce it with the help of spreadsheet and graphing software. The exercise can be used as a laboratory or an independent study for a student of introductory physics to provide an introduction to scientific research…

Learning styles have a big contribution to the academic performance of a student. Awareness of one's learning styles will help a person maximize his potential in accumulating learning to the best of his ability with the use of his preferred learning styles. The teacher's awareness of the student's learning styles will help him/her select teaching…
