In an effort to increase student comprehension and retention of basic chemistry concepts within a college level general chemistry course, a series of activities were created. These activities are referred to here as integrated problems. They were developed to help students by continuously reviewing key concepts and incorporating new material into…

Open-ended, inquiry-based multiweek laboratory exercises are the key elements to increasing students' understanding and retention of the major biological concepts. Including original research into undergraduate teaching laboratories has also been shown to motivate students and improve their learning. Here, we present a series of original…

Contains a set of questions (plus possible, but certainly not uniquely satisfactory, answers) requiring no more than a concurrent first-year, college level course, a data handbook, and a willingness to apply fundamental chemical ideas to the systems which surround us. (Author/TS)

The third volume of a three volume study of the development and effectiveness of a computer-assisted instruction (CAI) course in undergraduate Physics contains the CAI curriculum. It is broken up into two parts, that is the 1500 CAI course and the problem sets presented via the 1440 computer. For a background and summary of the project see volume…

Presents four questions (and provides answers) related to biology and chemistry. Items are concerned with genes, sodium transport, osmosis, and early earth history. (RH)

Presents five questions with answers regarding chemistry and living systems and ecology. (RH)

Presents questions and answers pertaining to yeast fermentation, oxygen content of the air, nutritional requirements of hot water bacteria, the hydrolysis of acetyl coenzyme A, and the stratified distribution of life in the Black Sea. (MLH)

Presents the second in a series of articles in which problems related to introductory physics courses are presented. The twenty problems deal with nearly all aspects of physics and are presented in a practical and thought-provoking manner. (RR)

Questions and answers to biochemistry four topics are presented. Items include fatty acid synthesis, reaggregation of sponge cells, enzymic degradation of pollutants, and energy requirements of organisms. (RWH)

Presents two exam type questions with answers relating to organic chemistry and organic photochemistry. (SL)
