Describes a game developed for school children which addresses part of the Science National Curriculum. The board is a human body with organs on view. Questions relate to different organ systems, body parts, and processes. Topics include breathing, digestion and metabolism, blood and circulation, and the sensory organs and teeth. (AIM)

Discusses a computer simulation designed as an educational tool for students to observe predator-prey oscillations and experimentally investigate how changes in life histories affect predator and prey densities. Provides hands-on interaction with such theories and with mathematical models. Available to any instructor for curriculum use. (AIM)

This study compared the achievement of biology, physics, and chemistry students in Higher Level (HL) International Baccalaureate (IB) programs with achievement of students in Subsidiary Level (SL) IB programs and regular Alberta (Canada) programs (n=708 students). Students in IB out-performed students in regular programs. Within IB, HL and SL…

Provides a brief survey of informatics, defined as the application of information technology to various fields, with respect to its historical background, disciplinary identity, fundamental aspects, applications, and challenges. Highlights include biological, clinical, dental, environmental, geomatics, health, legal, management, medical, museum,…

Responds to article "Comparing School Systems to Explain Enduring Birth Date Effects". Addresses article in relation to England and Wales. Refutes argument that selective promotion is a mechanism for the continuation of the birth effect in schools. Agrees that this phenomenon is worthy of further research. (CAJ)

Uses the case study approach to introduce students to the relationship between science and society. Develops an awareness of ethics, specifically on DNA research, through computer simulations and Internet conferencing. (Contains 20 references.) (YDS)

Details a project in which successful DNA analysis techniques were developed by students and their teacher in a rural school. Focuses on a study of sage grouse. (DDR)

Discusses children's age and academic performance within the school year. Reveals early differences show disadvantage among the youngest in the year groups. Attributes this difference to biology or individual psychology. Argues there is no explanation for why the youngest are disadvantaged in some countries but not in others. (CAJ)

Describes an investigation of the associations between students' perceptions of laboratory environment and their attitudinal, cognitive, and practical performance outcomes. Assesses student outcomes in three distinct areas: (1) student attitudes; (2) achievement on a written examination; and (3) practical performance, specifically in the biology…

Presents a protocol that gives students hands-on experience in generating a meaningful physical map of a circular molecule of DNA. Topics include agarose gel electrophoresis, logic of restriction maps, extracting data from an agarose gel, managing data from gels, experimental protocol, loading gels, electrophoresis, photographing gels, collecting…

Summarizes the benefits of using hydroponics in school for investigational work. Lists requirements and includes advice on suitable plant choices. Outlines the various growing systems and growing media and provides suggestions for science investigations using hydroponics. (DDR)

Describes an outdoor unit of study that enables students to realize the cause and effect relationships that exist within the ecosystem. Provides activities that help students understand how these interrelations can be easily disrupted, resulting in habitat destruction. (DDR)

Describes an innovative high school program that uses oceanography, mathematics, and science as common threads in the instructional program. The program utilizes an innovative class structure, community involvement, and hands on activities. (DDR)

Introduces a community service-learning project and shows how the community photography project captures the essence of biology and fosters curriculum collaboration between high school and elementary students. (KHR)

Describes a study providing evidence of how students' talk and writing about the nature of science differs depending on the particular scientific topic under discussion. Describes the relationship between theory and evidence, warrants for belief, and nature of observation. (Contains 25 references.) (Author/YDS)
