Compared the effects of using various computer software programs on the attending behavior of children with attention-deficit hyperactive disorder (ADHD). Found that the attention of ADHD children increased while they used software with a game format when animation was not excessive. Other factors affecting nonattending behaviors included the…

Begun in 1989, the LabNetwork is a telecommunications network for secondary science teachers and their students. Summer workshops provide teacher training in the network computer software and teaching methods based on student science projects. The development of a collaborative network-based "community of practice" is described. (SV)

A physics and chemistry teacher from rural Elmira High School (Oregon) describes his own and his students' experiences with the LabNet teacher telecommunications network and related project-based science instruction; the reactions of teacher colleagues and administrators to LabNet; and technological, psychological, and resource-related barriers to…

A science teacher at small, rural Sheridan High School (Oregon) describes the development of a three-county telecommunications network for science teachers; benefits of the network in relieving teacher isolation and providing resources; and teacher and student use of the network in project-based science instruction. (SV)

A workshop introduced middle-school science teachers in rural Georgia to telecommunications as a means to relieve professional isolation. However, two years later, no participant was using an online system. To be attractive, a teacher network must be versatile, user friendly, inexpensive, and used by enough teachers to provide daily dialog. (SV)

A science teacher at an Alaska correspondence school discusses the educational uses of electronic mail (enhancing the relationship between teacher and distant student, encouraging early computer literacy and reflective communication skills, and promoting interschool collaboration) and describes a telecommunications-based science project involving…

A physics teacher at rural Cedar Falls High School (Iowa) describes how teacher telecommunication networks provided ongoing support following summer teacher workshops, his inability to get fellow teachers engaged in telecommunication, and the benefits of a telecommunication network to rural teachers. (SV)

Suggests that research on teacher telecommunication networks such as LabNetwork must examine how a network contributes to the teaching practice and professional development of rural teachers and must be embedded in an understanding of the conditions of rural teaching. Discusses network potential to provide space for a professional "community of…

Discusses the impact of the telecommunication experience on student skills (thinking, reading, writing, group dynamics, and basic computer literacy) and student motivation and attitudes (educational attitudes, self-concept, and world view). Discusses indirect learning as the heart of the project approach to education. Lists research questions on…

Teacher decisions to begin using telecommunications in professional practice are influenced by technical literacy, time to learn, hardware-software compatibility, ease of use, cost, and perception of benefits. Issues for experienced users include funding, administrator attitudes, interpersonal relationships on the network, classroom impact,…

Recommends ways in which the National Science Foundation can promote educational reform through the development of a national telecommunications system accessible to all schools and through support for project-enhanced science learning. Describes existing networks, factors in making a national network useful and accessible to teachers, and…

Explored one student teacher's ideas and practices, together with the messages about teaching for procedural and conceptual knowledge that were presented by the student's teacher education program. Found that the student teacher taught, learned to teach, and had opportunities to learn to teach for procedural knowledge more often and more…

Twenty-four sixth-grade children participated in clinical interviews on ratio and proportion before receiving instruction in the domain. Student thinking was analyzed in terms of mathematical components critical to proportional reasoning. Two components, relative thinking and unitizing, were consistently related to higher levels of sophistication…

Compared the problem-solving and computational skills of first-grade students whose teachers had participated in staff development to learn to teach using a Cognitively Guided Instruction framework to first-grade students whose teachers had not. Students in experimental classes performed significantly better in solving word problems and completing…

Reviews chapters of this book on probability in mathematics education. Topics discussed in the chapters include a historical perspective of probability, an epistemological perspective of probability, an overview of the psychological research on probability learning, computers in probability education, and an analysis of the probability curriculum.…
