Contains articles on digestive enzymes in grasshoppers; bird and badger observation; reactions between hydrochloric acid and sodium carbonate solutions; observing the migration of ions; pupil's heating skills (Bunsen burners); photolysis experimentation; capillary kinetics; experience with trireme; connection circuits; special relativity; a…

Describes the implementation and evaluation of a nondirected student research project that aimed at acquainting students with some of the procedures used by physicists in the real world. Outlines specific project designs used by the students. (JRH)

Describes techniques and equipment which allows school microscopes to perform crossed-polarized light microscopy, reflected light microscopy, and photomicrography. Provides information on using chemicals from a high school stockroom to view crystals, viewing integrated circuits, and capturing images on film. Lists possible independent student…

Relates a middle school teacher's experiences using the project-based science approach with two groups of seventh graders. Describes the features of project-based science and the content and activities of the units taught. Discusses the challenges of implementing this approach and compares the strengths and weaknesses of project-based and…

Presents a cooperative activity between home and school in which parents and students examine the growth of a variety of bulbs. Bulbs are taken home to sprout and returned to school to monitor their growth. Students gather data, hone observation and graphing skills, and communicate with their parents on the project. (MDH)

Describes the preparation and importance of a project where junior high school students stenciled "No Dumping! Flows to the Bay!" on storm drains in the area of their school. (PR)

Describes combining the simple activity of collecting monthly student height measurements with the technology of using a computer spreadsheet for a year-long activity that teaches measurement and data manipulation. (PR)

Presents three articles that describe different ways of teaching the scientific method using cookies ("The One-Hour Science Fair"), cola ("Are All Medium Colas the Same Size"), and television ("Timing Televiewing"). (PR)

A Korean science teachers' discursive practises were examined with a view to identifying pedagogical roles performed through his talk. Data came from the video recordings of classroom sessions where students presented their science projects and exchanged questions and answers during the presentations. Transcripts were developed and analysed in a…

The Chemistry/Physics Program at Evanston Township High School was designed to provide an environment for the rigorous teaching of advanced science and mathematics to accelerated students. This type of student makes up the bulk of students in the Advanced Placement Chemistry and Physics classes. However, there is a small number of students who…

Through an interactive partnership, fifth-grade students collected data on plants and joined an active scientific community of working scientists. This Web-based Integrated Science Environment (WISE) project involved asking questions about plants, growing plants in the classroom, and discussing their data with scientists online. (Contains 5…

STEM--science, technology, engineering, and mathematics--has become a fixture of the education debate, and much effort already has been put toward improving student performance. Yet troubling statistics persist: On the latest round of testing for the National Assessment of Educational Progress (NAEP), only 40 percent of fourth graders nationwide…

Many studies have been made on the impact of supplemental instruction in supported courses, with most showing significantly better examination results for students attending supplemental instruction in comparison to those who do not. However, remarkably little attention has been devoted to following up whether the benefits of supplemental…

A nanotechnology module was developed for ninth grade students in the context of teaching chemistry. Two basic concepts in nanotechnology were chosen: (1) size and scale and (2) surface-area-to-volume ratio (SA/V). A wide spectrum of instructional methods (e.g., game-based learning, learning with multimedia, learning with models, project based…

In recent years, a number of National Research Council reports have emphasized the need to improve science education and enhance science literacy for all students. In addition, the newly released "A Framework for K-12 Science Education" advocates engaging students in scientific practices and disciplinary core ideas. Children are not learning…
