Describes a research program that has active areas of research ranging from hydrology, water chemistry, geology, gene cloning, satellite image analysis and remote sensing, and molecular biology. Provides information on selection procedures, design of program, benefits, and names of participants. (RT)

Describes a micromanipulator that is inexpensive, simple to build, rugged, and capable of several modes of operation beyond those of other types. It can, for example, be used with its controls quite remote from the tool holder and microscope or be controlled by computer. (JN)

Describes a system in which organic chemicals are recoded for inventory control and reshelving purposes. The system works well in undergraduate organic chemistry or biology laboratories but can be expanded to handle a larger and more complicated inventory. (JN)

Shares excellent quotes that can be used in the classroom to enliven or punctuate a topic of discussion. (ZWH)

Discusses a study where the Myers Briggs Type Indicator was given to 146 students in a general biology course at a large state university. Results indicate that the introverts were the highest achievers and the perceiving types were the lowest achievers. (PR)

A variety of problems, ranging from vocabulary to pre-existing belief structures, prevent efficient learning among biology students. Several of these problems are discussed, with implications for teaching college level biology addressed. (JN)

Describes a classroom exercise that uses a letter from Max Delbruck to George Beadle to stimulate interest in the mechanics of a nonoverlapping comma-free code. Enables students to participate in the rich history of molecular biology and illustrates to them that scientists and science can be fun. (JRH)

Discusses how the constructivist approach to learning can aid in helping students to experience more meaningful learning. Discusses cooperative group learning and the concept of constructivism; constructivist teaching formats; and whether the constructivist approach works. (ZWH)

Presents the results of a survey on evolution given to 392 university students in western Pennsylvania. Concludes that, although nearly three-quarters of the students say they believe in the theory of evolution, most do not understand the mechanism behind it. (PR)

Explains an experiment in which the rotation of a patch of skin on a tadpole results in a frog with rotated spots, proving that the spot pattern is determined long before it becomes visible. Procedures used are included. (DH)

Outlines steps to generate cell samples for observation and experimentation. The procedures (which use ordinary laboratory equipment) will establish a short-term primary culture of normal mammalian cells. Information on culture vessels and cell division and a list of questions to generate student interest and involvement in the topics are…

Discusses the need for students to develop understanding of science by designing their own laboratory experiments. Lists examples of concepts that can be taught through student-designed biology experiments. Also gives suggestions and guidelines to ensure that laboratory time is manageable and productive. (DH)

Describes the use and benefits of prosection--a dissection performed in advance and used by "nondissecting" students for detailed observation and study--in undergraduate laboratories. (PR)

Describes a laboratory experiment which focuses on the importance of water in germination and seedling emergence. Discusses the activity's design, expected results, and possible application. Offers suggestions for extending the experiment. (ML)
