Describes laboratory techniques designed to familiarize students with meiosis and how microscopic preparations of meiosis are made. These techniques require the use of fresh or fixed flowers. Contains 18 references. (DDR)

Describes a year-long, schoolwide project that brings the ocean environment into the classroom and develops cross-disciplinary understandings for students. Presents details of the physical environment within the school, the history of the project, and the rationale and advantages. (DDR)

Reports on a study that used high school students to test the assumptions of the multiple hypothesis theory posited by Lawson to explain the essence of scientific reasoning. Contains 19 references. (DDR)

Examines the interest level of Chilean students in physics and technology in light of unacceptable performance levels in these areas. Relevant thermodynamics problems applicable to students' daily lives generated more interest. Discusses the importance of presentation to student acceptance of the curriculum. (AIM)

A study of secondary teachers before and after introduction or the Northern Ireland Curriculum (1989-1995) found some improved continuity between primary and secondary science. However, few teachers had taken account of children's earlier experiences in planning secondary science programs. (SK)

Details the four-year consensus-building process in the United States on what students should understand and be able to do in science after 13 years of schooling. The product of this process is a document known as the National Science Education Standards. (DDR)

Describes a seventh-grade science course that is based on the phenology of the seasons, uses the outdoors on a regular basis, and uses reference books and field guides. (DDR)

Presents a modification of a procedure for making and launching hot air balloons made out of garbage bags. Student instructions for balloon construction, launching instructions, and scale diagrams are included. (DDR)

Provides technical information about digital photography including cost, quality, and applications in classrooms. Recommends that digital cameras be used for student classroom presentations and record keeping. (DDR)

Part One presents empirical results of students' epistemological conceptions of laws, hypotheses, theories, and models. These results are discussed in relation to research results from different recent publications. Part Two gives an outline and analysis of a two-year program for teaching epistemology in a physics course. (AIM)

Argues for greater emphasis in the science curriculum on the spiritual and moral contexts in which scientific ideas have been developed. (JRH)

Reports on a longitudinal study that mapped the transition between primary and secondary school from a student perspective. Explores how this transition impacts the way students think about, learn, and enjoy science at school. Describes the changes in organization, curriculum, and teacher-student relationships that occur at this time. Contains 52…

Describes a rigorous, individualized science curriculum in an alternative program that gives students some choice of what to study and provides them with their own time frame in which to work. Discusses design and implementation, high standards for all, and benefits and bonuses. (JRH)

Describes a system of regional research conferences for students in which they were invited to display a team poster and/or give a presentation on any interesting aspect of investigative work within the curriculum or within extracurricular activities. (DDR)

Traces the history of the observation of the production of electric sparks and the early history of battery design. Detail is provided about laboratory experiments performed by Robert Bunsen, who spent a great deal of time developing an efficient and comparatively cheap battery. (36 references) (DDR)
