Whether the goal is to identify and describe trends and variation in populations, create new measures of key phenomena, or describe samples in studies aimed at identifying causal effects, description plays a critical role in the scientific process in general and education research in particular. Descriptive analysis identifies patterns in data to…

A core component of many new educational programs funded under the "No Child Left Behind Act of 2001" is that they be based on scientifically based research. Like others in the educational community, counselors and counseling researchers welcome the opportunity to empirically test the validity of their practices and demonstrate that what…

Analyzes the relationship between Karl Popper's philosophy and a 1912 paper by F. G. Hopkins which was instrumental in convincing scientists about merits of the vitamin theory. Concludes that Hopkins' work was convincing because it subjected a theory (which was the center of attention) to the severest possible tests, supporting Popper's position.…

Some basic tips on writing periodical articles about research are provided: (1) learn to work with scientists and (2) ask for appropriate background material before an interview. Research questions, interpreting data, drawing conclusions, and verifying results are discussed. (MLW)

Outlines the chemistry of the rapid synthesis of relatively large DNA fragments (100-200 monomers each) with yields exceeding 99 percent per coupling. DNA synthesis methodologies are outlined and a polymer-supported synthesis of DNA using deoxynucleoside phosphoramidites is described with structural formulas. (YP)

Introductory biology students at a major university completed a field project which taught them investigative skills in scientific research, including the scientific method and substantiation of their results through use of periodical literature. Librarians became actively involved by providing library instruction as part of the project. Sample…

Demonstrates what theoretical physicists make a rule using juggling. Provides the thinking process and calculating procedure. (YP)

Describes the use of James Watson's book, "The Double Helix," as a multidisciplinary way of introducing students to actual science; the scientific method; dilemmas encountered in the world of research; and the rich setting of personalities, politics, and history in post-World War II Europe. (MKR)

Describes experiments used during recent history to explain the nature of the quantum world. Explains the essential elements of experiments using polarized light and magnetic flux. Illustrates differences between classical theories in physics and quantum theory. Shows how experiments in the microscopic and macroscopic world appear to support…

Describes a format for experiments where students not only conduct their own experiments but also become part of a model scientific community by writing research proposals, applying for grants, submitting their work to colleagues for scrutiny, participating in a symposium to present their findings, and creating a scientific journal to publish…

This paper is based on the view that, although scientists rely on research values such as predictive accuracy and testability, scientific research is still subject to the unscientific values, attitudes, and emotions of the scientists. It is noted that undergraduate students are likely not to think critically about the science they encounter. A…

Offers an improvement over the least-square method that is particularly applicable to fitting the Beer-Lambert equation. Provides typical data and the corresponding graphs. Lists six references. (YP)

Lists suggestions for improving experiments involving effects of various chemicals on Daphnia heart rate. Concludes that the real value of these experiments lies in what they teach about variations in the response of living things to chemicals and the difficulties researchers encounter when doing experiments with living things. (JRH)

Relates how Charles Martin Hall discovered the method of making pure aluminum metal in 1886. Retraces the events and steps that led to the process of aluminum purification. Includes diagrams of the apparatus used in the investigations. (ML)

Offers a concise, abstract description of the scientific method different from the historical, philosophical, and case-study approaches, which lead to comprehension of this method. Discusses features of scientific models, dynamic interactions underlying scientific progress, ways that scientist successfully understand nature, mechanisms for…
