This study investigated the impact of different modes of scaffolding on students who are learning science through a web-based collaborative inquiry project in authentic classroom settings and explored the interaction effects with students' characteristics. The intervention study aimed to improve "domain-specific knowledge" and "metacognitive…

Investigates reasoning strategies students use in solving stoichiometric problems and explores the relation between these strategies and alternative conceptions, prior knowledge, and cognitive variables. Results show how stoichiometric relations produce conflicting situations for students leading to conceptual misunderstanding of certain concepts.…

Presents strategies for encouraging dialog with students from eliciting preconceptions to bringing closure to a unit. Includes the general structure of an instructional unit that employs dialog, strategies for teachers to use, and strategies for students which include active listening. (DDR)

Reports a study that examined the effects of conceptual orienting questions and differences in prior knowledge on factual learning and problem solving in biology. Tenth graders who participated in control or orienting questions groups completed posttests. Results indicated that question groups outscored the control group. (SM)

Lends support to the idea that the quality of the cases used in problem-based learning affects the nature of student learning in this context. Outlines seven principles adapted from research on learning and cognition that can help guide case design. Contains 22 references. (DDR)

Argues that the life sciences offer potential for practical work to be undertaken outside the classroom. Explores a rationale for such work and draws on reported studies from a number of countries. Contains 44 references. (DDR)

Describes a study that was conducted to determine how high school students would solve an information problem: specifically, what prior learning students had about information seeking and use, and how they would use that prior learning. Highlights include group work; topic selection; and reasons for unsuccessful use of libraries, including…

Describes a study that examined the effect of computer programing experience on the mathematical problem solving achievement of high school students. The variables studied are discussed, including gender, ability, socioeconomic status, prior math experience, and access to a home computer, and a path analysis model is explained. (34 references)…

A collaborative of secondary teachers and administrators, university faculty, and administrators formulated a four-phase, field-based teacher education program that included: providing for self-directed experiences with adolescents; establishing an understanding of teaching and schools in modern society; developing skills to meet the needs of…

Reviews the traditional definition of practical work in science, offers a different definition of it, and points out that practical work is not always laboratory based. Discusses the logistics of coordinating fieldwork. Contains 17 references. (DDR)

The IADIS CELDA 2012 Conference intention was to address the main issues concerned with evolving learning processes and supporting pedagogies and applications in the digital age. There had been advances in both cognitive psychology and computing that have affected the educational arena. The convergence of these two disciplines is increasing at a…
