Argues that using in-class worksheets are versatile and can be tailored to meet specific goals. Finds that worksheets are effective for confronting preconceptions, ensuring class participation, and increasing student/teacher interactions. (CCM)

Discusses the use of information technology, technology diffusion and reinvention, and technology adoption and implementation. Considers the change process in higher education and the need to develop good computer habits and overcome old habits that are based on old teaching and learning methods. (LRW)

Presents a study in which three classes of grade 10 students worked with graphics calculators throughout, five classes used them for approximately two months, and four classes did not use them at all. Posttest results showed that students who had worked with graphics calculators tended to attempt more problems and obtain higher test scores than…

Argues that Darwinian evolution provides a framework for understanding how a polymer such as RNA might have arisen and perpetuated itself in a changing environment. Also explains how one genetic system invents another. (DDR)

Recommends the use of ethical issues to engage college nonscience majors in discussion. Focuses on using problems that pertain to biomedical situations and decisions such as transferring living parts from one type of organism into another. (DDR)

Describes several teaching exercises combining art and ecology that have been used in advanced ecology courses and may be adaptable to art criticism. Considers the nature of art, the ecological content of art, and the artistic form of ecological models. Contains 40 references. (DDR)

Describes the care and breeding of zebra fish, suggests various experiments and observations easily performed in a classroom setting, and provides some ideas to further student interest and exploration of these organisms. (DDR)

Proposes models for the lichen symbiosis, genomic, and plasmid DNA and fluid mosaic membrane structure. The models operate at the classroom level with the classroom becoming the cell in a DNA exercise with students as interactive components. (DDR)

Presents a research and exhibit development aimed at increasing the understanding of family learning in science museums and identifying the characteristics of successful family learning exhibits. Concludes that using the seven characteristics of successful family exhibits as a guide to exhibit development proved to be an effective strategy for…

Describes how a fourth-grade homework assignment sparked a lifelong passion to study Mars. A Mars scientist shares how he became interested in his career. Also provides a status report of the agenda of Mars missions and includes information on related resources. (DDR)

A sociolinguistic analysis was conducted of a job-training program for female welfare recipients that simulated construction work sites. The instructor encouraged trainee responsibility for learning. Negotiation and purposeful talk helped develop competence. (SK)

Sixty-three college students worked with a computer simulation in which gradually increasing model complexity (model progression), model progression plus small assignments, or a control condition without either were used. Definition knowledge increased for all three conditions, but intuitive knowledge gain was greater for the two experimental…

Examines strategies used by preschool children to subdivide items and focuses on how counting and sharing relate to one another. Indicates that children exhibited alternative strategies--suggesting use of a recipient as a mental cycle-marker and an adjacent recipient strategy--with pauses between allocations suggesting a re-presentation of lots…

A theory-practice model for work-based learning is premised on the idea that learning can be acquired through practice. It incorporates three strategies that can be sequenced: action learning, action science, and communities of practice. (SK)

Discusses the decision to offer a course by online delivery and describes the development of a Masters course that used collaborative learning as the teaching/learning method. Explains the theoretical basis for collaborative learning; discusses collaborative learning as a constructivist activity; and relates it to instructional design for online…
