Introduces a project that focuses on understanding scientific inventions and reflecting upon the creativity involved. Explains teacher preparation, locating accidental inventions and discoveries, and the daily bases of the project. Also provides information on student assessment. (YDS)

Reports on a study that involves the analysis of chemistry textbooks at the college freshman level to determine the degree to which they address developments in the history and philosophy of science. Twenty-three textbooks were evaluated on eight criteria. Contains 108 references. (DDR)

Presents an experiment in which students use laboratory data to calculate the interphase mass transfer coefficient for a fluid passed over a sphere and obtain correlations for solid-gas mass transfer. Students develop a realistic mathematical model to describe the sublimation process. (DDR)

Explains how student projects enable second-year chemistry students to gain their first experience studying a chemistry-based problem before undertaking a major project during the third year of their chemistry studies. (DDR)

Describes a project that integrates active learning into service learning targeting both college students and middle schools students wherein college students perform chemical demonstrations for middle school students. (YDS)

Investigates the reasons for low academic achievement in chemistry among Hispanics students at the college level. Focuses on gender and ethnicity and uses a 6-question instrument specifically designed to identify the reasons for lack of success. Includes 33 references. (YDS)

Describes materials developed for key stage 4 for the improvement of student thinking skills that are used to explain atomic structure and bonding. Tests student understanding by introducing seemingly plausible, yet possibly incorrect, explanations of situations. (Author/YDS)

Demonstrates how forensic science can be used as a framework for generating student interest and learning in chemistry and promoting critical thinking. The "Who Dunnit?" forensic science workshop was developed by undergraduate students and is one element of a two-week residential summer outreach program that seeks to develop interest in…

Presents a general chemistry stoichiometry experiment using materials involved in everyday life. From this activity, students learn that a chemical reaction occurs when an Alka-Seltzer tablet is dropped into water. Students also practice plotting experimental data through the use of a graphing program. Interpretation of the graph helps them…

Introduces a chemistry course developed at Northeastern University and discusses the improvements to increase the quality of education offered to graduate students. (Contains 20 references.) (YDS)

Introduces an undergraduate level problem-based analytical chemistry laboratory course integrated with an environmental law course. Aims to develop an understanding among students on the use of environmental indicators for environmental evaluation. (Contains 30 references.) (YDS)

Compares phase diagrams relating to the solubilities and melting points of various substances in textbooks with those generated by a spreadsheet using data from the literature. Argues that differences between the diagrams give rise to new chemical insights. (Author/MM)

Presents several variations on a demonstration in which alcohol vapors are combusted in large small-necked bottles, causing a blue flame to shoot from the bottle's mouth. Describes variations with different pure alcohols, temperature, alcohol/water solution concentration, oxygen concentration, type of container, and the addition of salt for color.…

Introduces a "cafeteria-style" grading (CSG) approach in science instruction which allows students to decide on the course components and their weight in evaluation. Considers student success, motivation, and self-awareness for the evaluation of CSG. Uses portfolios, writing assignments, web page development, and traditional evaluation methods for…

Describes a project that applies problem based inquiry learning units to an introductory chemistry laboratory curriculum. Uses web technologies to support instruction. (Contains 25 references.) (YDS)
