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…

Considers the circumstances surrounding instances where help is sought and/or provided in a collaborative problem-solving situation. Analyzed videotaped observations of nine groups of three grade 5-6 students working over three 45-minute periods on an open-ended task. Defines hierarchical levels for questions, answers, and outcomes. Indicates some…

This article discusses the challenge that students with disabilities face in high-school settings in trying to succeed within the general education curriculum. The Concept Anchoring Routine is profiled as a way to help adolescents connect new information they are expected to learn to information that is already familiar to them. (CR)

Demonstrates how students who use background knowledge, context, morphology, and dictionaries learn words more effectively. Adapts a vocabulary web consisting of eight identical bubbles to provide students with a word map, intertwining most of the elements to clarify word meaning described by J. M. Harmon as essential to vocabulary instruction.…

Examines how components of the concept of function (variable, domain, and range) and the process-object duality in its nature emerge as highly relevant to student learning in various mathematical contexts related to linear and abstract algebra. (Contains 22 references.) (ASK)

Urges education to help students learn through conceptual thinking. States that the first step must be to teach the subtleties of words--without a command of the language, important discriminations can be confused. Asserts that if students are to think well conceptually, surface language must dissolve, and alternative ways to communicate must be…

Reports that although a rhetoric of visible text based on page layout and various design features has been defined, what a writer should know about design is rarely covered. Describes and demonstrates a scope and sequence of learning that encourages writers to develop skills as text designers. Introduces helpful literature that displays visually…
