Reports on a study of the contributions fieldwork made to Spanish secondary students' (n=67) understandings of concepts and principles of ecology. Concludes that fieldwork helps clarify ecological concepts and intervenes directly in the development of more favorable attitudes toward the defense of the ecosystem. Contains 47 references. (Author/WRM)

Presents a lesson that addresses the scientific aspects of the evolution versus special creation controversy by having students gather evidence from the fossil record and analyze that evidence using critical-thinking skills. Contains 13 references. (WRM)

Examines whether secondary science teachers in England give students opportunities to develop and rehearse the skills of argumentation during their lessons. Finds that classroom discourse was largely teacher-dominated and tended not to foster the reflective discussion of scientific issues. Contains 43 references. (Author/WRM)

Describes how oral and written-discourse processes in a high school physics class are related to sociocultural practices in scientific communities. Finds that students' appropriation of scientific discourse was related to the framing activities of the teachers and the social practices established over time in the classroom. Contains 74 references.…

Argues that the United Kingdom's National Curriculum recommendations regarding data analysis tasks do not explain the specific activities clearly enough to assist teachers in deciding what practices to follow. Presents research that shows that the range of data-analysis tasks that pupils can perform depends on the type of data as well as on the…

Describes an activity to help students understand how feathers help insulate a bird's body. (WRM)

Describes a study of the ways in which 9- to 16-year-old students attempted logical problems related to coordinating theory and evidence when the theories in question are scientific. Finds that most students made some reference to evidence in selecting and using their explanations, although most students also seemed capable of holding theory and…

Beginning secondary students find it easier to express their understanding of scientific evidence verbally rather than in writing. Concludes that much work can be done to improve the critical nature of the dialog pupils enter into in their written work, thus making their level of procedural understanding more clear. Contains 27 references.…

Discusses environmental resource assessment research conducted by undergraduate students as part of a non-science majors' chemistry course at Santa Clara University. Describes project procedures and course grading, chemistry connections, learning goals and outcomes, and implementing change on campus. (WRM)

Presents ideas for teaching elementary school children about scientific inquiry methods. Recommends a Planning Board to scaffold students' thinking as they plan and conduct scientific investigations. (WRM)

Whether boys and girls shared equally in performing behaviors required in hands-on activities in the performance-based science classroom was studied over the school year with 165 students in grades five through eight. Being actively involved predicted students' year-end science attitudes, and boys tended to handle the resources more often. (SLD)

Presents an exercise in which cutouts or outlines of dinosaur footprints placed independently or in sets on the floor and laboratory benches are used to model dinosaur trackways. The nature, size, speed, and specific behavior of the trackmaker are determined from the trackways and from student-derived data as well as from diagrams and models based…

Explains the development of an interdisciplinary unit in which students learn basic chemistry and laboratory techniques while practicing English, mathematics, art, social studies, and leadership skills. Includes details about lab activities, assessment strategies, and science extensions. (DDR)

Explains the interrupted journal case study method which integrates content, process, and application in an environmental biology course. Provides a sample case on wetland delineation and describes strategies to develop effective case studies in environmental education. (YDS)

Presents an activity of students hunting for dirt in the classroom to launch a study of the environment and to provide children with an exercise in which they learn and use the skills of collecting, labeling, organizing, observational drawing, classifying, hypothesizing, and summarizing. (PR)
