Explains the technology of biometrics, the science of identifying a person by unique physical characteristics, and its application in the fight against terrorism. Argues that biometrics, such as hand readers, fingerprint readers, and eye scans, are reliable and efficient. Also describes proximity cards, digital tracking systems, and smart cards.…

Investigates the association between attitude towards the philosophy of science and academic qualification professional training. Analyzes responses from 33 A-level biology teachers to a questionnaire and reports from teachers in Harare on their school contexts. Suggests that the differential distribution of facilities and resources across school…

Points out the importance of socioscientific aspects of laboratory activities for the development of understanding of different cultures' contributions to science. Describes a lesson on gene splicing using the 5E Learning Model. (YDS)

Describes the results of a controlled experiment that tested the effectiveness of Lord's teaching model in: (a) helping students achieve better grades on standard midterm exams; (b) developing higher level thinking skills; and (c) modifying attitudes towards biology at a large urban university. (Author/SOE)

Presents an inquiry-based research model for high school students to engage in inquiry learning. Provides students and teachers with a better understanding of inquiry and greater confidence in their critical thinking skills. (Author/SOE)

Describes a Computer-Assisted Instruction (CAI) package covering biology concepts for an entire school year and evaluates the effect of this CAI on learning. Findings indicate positive effects of CAI on achievement and attitude. Contains 18 references. (JRH)

Describes the use of manipulatives to teach the fundamental concept of limiting factors and presents a series of questions that can be used to test whether students are harboring some of the most common misconceptions about limiting factors. Includes applications to discussions of cultural eutrophication and vegetarianism. (JRH)

Discusses the role of techniques of DNA analysis in assessing the genetic relationships between various species. Focuses on wolf-dog evolution using DNA evidence and historical data about human/wolf-dog relationships. (DDR)

Presents an activity that demonstrates how a traditional activity can generate questions not typically raised in a conventional course. In the context of astrobiology, students can connect to an intriguing endeavor, the search for extraterrestrial life. (DDR)

Outlines several recommendations for teaching probability in the secondary school. Offers an activity that employs simulation by hand and using a programmable calculator in which geometry, analytical geometry, and discrete mathematics are explored. (KHR)

Compares two delivery methods for a course in genetics and evolution: (1) studio teaching involving teamwork by students, hands-on exercises, and minimal lecturing; and (2) an interactive lecture demonstration method. Uses pre- and post-testing of basic concepts to evaluate the effectiveness of each method. Suggests that studio techniques are a…

Traditional ecological knowledge has value not only for the wealth of biological information it contains but also for the cultural framework of respect, reciprocity, and responsibility in which it is embedded. (Contains 48 references.) (DDR)

Investigated is the ability of high school pupils and university students to answer questions based on relationships within food webs using sound ecological principles. Research methods used and the results of this study are discussed. (CW)

Presented are suggestions for using human pedigrees in the classroom and a generic pedigree that can be modified and used by instructors to provide variants for analysis. Eight single-gene mechanisms of inheritance are defined for use in this activity. (CW)

Presented is a game using different types of dominoes that represents growth of seeds from the beginning of the universe. Included are diagrams of the types of seeds, instructions, and examples of the game play. (KR)
