Investigations that facilitate experimental design, the concept of replication, data analysis, and other aspects of scientific study are described. A list of materials, the recommended plants, and the directions for building the hydroponics unit are included. (KR)

Describes experiences of a fifth grade teacher who converted her classroom to a whole language teaching and learning environment. In her child-centered classroom, she emphasizes student empowerment and decision making, cooperative learning, and flexibility. Her top priority is for students to participate and learn critical thinking and…

Describes a method of teaching geology and scientific writing to nonscience students that combines active integration of lecture, reading, and laboratory materials with field observations into a writing assignment on a real scientific problem. The writing assignment is completed in stages: a prospectus, a detailed report outline, a bibliography, a…

Changes in college biology instruction in recent years reflect the changes in college instruction in general: information-dense textbooks, high-technology laboratory experiments, complex computer simulations, and easy exchange of data and ideas. Educators can now ask questions unthinkable by their classical forebears, and students can participate…

Examines the Teacher Assistance Team (TAT) approach in providing all students with individualized, supportive instructional alternatives in the classroom. Explains how the TAT is a cost- and time-effective approach for providing teacher support in handling "slow learners" and letting teachers have ownership and responsibility in dealing with…

Shows how a successful bibliographic instruction program can be achieved through the interrelationship of program support, facilities, and growth by examining how the librarians at Brigham Young University (Utah) developed a proposal for, helped design, and obtained funding for a new bibliographic instruction facility. (Contains seven references.)…

Discusses computer labs in schools and argues that they are not effective in integrating computers into the curriculum. Highlights include acquiring computer skills for computer-related classroom activities; the quality of courseware; and a case study of a sixth grade social studies lesson that integrated the computer into classroom activities.…

Presented is a teaching progression that enhances learning through low-cost, manipulative transparencies. Discussed is instruction about restriction enzymes, plasmids, cutting plasmids, plasmid maps, recording data, and mapping restriction sites. Mapping wheels for student use is included. (CW)

Describes using the common house plant, "Coleus blumei," to illustrate gravitropic effects, phototrophic effects, and hormonal effects in plants. (PR)

Discusses the inherent flaws in considering and using the epistemology of the natural sciences as equivalent to a pedagogic basis for teaching and learning in the natural sciences. Discusses the difference between practicing science and learning to practice science. Concludes with the presentation of three new motives for the use of laboratory…

The life history of the Chironomus tentans can be observed in easily established and maintained laboratory cultures. Projects for the classroom include observing hydration of an egg mass; embryonic development, hatching and larval feeding; larval activity; and mating activity. (MDH)

Describes a study that explored the interplay between students' scientific epistemological views (SEVs) and their learning in school laboratory activities. Finds that students having SEVs oriented to constructivist views of science tend to focus more on negotiating the meanings of experiments with their peers than students with SEVs more in line…

Reports on a laboratory experiment where students measured their heart rate, blood pressure, mood, alertness, and cognitive performance. Measures showed significant circadian heart rhythm variations. They were strongly correlated and peaked at different times. Discusses the implications of this and students' reactions to the experiment. (MJP)

Discusses the lack of compassion in biology teachers for laboratory animals as well as their indifference to students' compassion for animals. Teachers see dissection as scientific method, whereas students may see it as cruel. If educators are repeatedly exposed to compassion for all life by students, they will eventually see the need for greater…

Provides suggestions to promote English literacy to students with hearing impairments in residential environments. Strategies include model reading and writing, read to children regularly and in American Sign Language, set up a writing center, encourage book sharing, set up a home library/reading center, and encourage ownership of books.
