Explores different curricular emphases in processes and content which reflect different goals and educational research traditions. Problem solving remains neglected in both areas. Draws on situated learning and social constructivist literature to provide insights into problem solving in technology education. Contains 54 references. (Author/PVD)

Summarizes the latest key brain research findings and invites educators to incorporate the biology of learning into teaching practices. Curriculum should be based on overarching concepts that help students understand and predict what is going on around them at school and in their communities. (PVD)

Social scientists are often concerned that research on biological causes of behavior will encourage biologically-based public policy. By simultaneously examining both social and biological causes of behavior, biosocial research models prevent simplistic biological thinking. Concludes that biosocial models clarify ethical problems rather than…

Describes how a cooperative learning environment can be created in the anatomy and physiology laboratory through the use of cooperative quizzes. Includes a brief introduction to the pedagogical theory behind cooperative learning and an evaluation of the effectiveness of quizzes compared with more traditional methods. (Author/PVD)

Presents a phenomenological study of student experience in a computer conference learning environment. Issues for students in conferences revolved around spatial disorientation. Students grappled with getting into a computer space, familiarity of use, getting stuck, and the class as a necessary evil within spatial issues. (Author/PVD)

Presents two experiments that demonstrate phase changes. The first experiment explores phase changes of carbon dioxide using powdered dry ice sealed in a piece of clear plastic tubing. The second experiment demonstrates an equilibrium process in which a crystal grows in equilibrium with its saturated solution. (PVD)

Presents three experiments to introduce students to different kinds of chromatography: (1) paper chromatography; (2) gel filtration chromatography; and (3) reverse-phase liquid chromatography. Written in the form of a laboratory manual, explanations of each of the techniques, materials needed, procedures, and a glossary are included. (PVD)

Lists 31 useful physics-related Internet sites to help physicists who are just starting to use the Internet. The sites are also useful in teaching or to assist students in doing research. Sites have a range of sponsors including physics organizations, government agencies, universities, and corporations. (PVD)

Understanding antibody structure and function is difficult for many students. The rearrangement of constant and variable regions during antibody differentiation can be effectively simulated using a paper model. Describes a hands-on laboratory exercise which allows students to model antibody diversity using readily available resources. (PVD)

Explains the problem of mission for nature centers. The nature center must organize itself to become recognized and treasured for preserving a precious piece of habitat and it must know the plants and animals that inhabit the specific place in which the nature center resides. (PVD)

Discusses environmental hazards, the problems of misinformation and contradictory information, and the problems for children in sorting out fact from hearsay. Includes tips for protecting children from environmental hazards and describes a program at the University of Washington that develops curriculum materials and other teacher resources. (PVD)

Describes the curriculum of the Lake Washington School District Environmental and Adventure School which included outdoor education on the school grounds and field and overnight trips. The curriculum theme was interdependent relationships, people and environments. Also included study of local natural history and Native American tribes. (PVD)

Offers pointers to keep in mind while planning an outdoor adventure. These include establishing clear behavioral expectations, having specific assignments for students to complete that focus their attention, being flexible in natural settings, communicating strategically, carrying props, and planning ahead. Includes a checklist for logistical…

Describes a program at Andrews University developed along with the Berrien County Intermediate School District that utilizes college faculty to provide instruction to talented and motivated high school students. Explains logistics (curriculum design, administrative arrangement, and financial aspects) of the program, challenges, and benefits.…

Offers a problem for teachers to try with their students. The problem is presented visually as a row of 15 connected squares and the task is to determine the number of rectangles. The goal is to encourage teachers to reflect on students' work and analyze classroom dialogue. (PVD)
