A project to develop science curricula for high-ability learners in grades K-8 reviewed curriculum materials and developed criteria for assessing curriculum materials, science concept papers, a scope and sequence model, and exemplary curriculum units. The curriculum centered on the role of students as investigators. Implications of the project are…

An experiment was performed to investigate the effects of practice and spacing on retention of Japanese-English vocabulary paired associates. The relative benefit of spacing increased with increased practice and with longer retention intervals. Data were fitted with an activation-based memory model, which proposes that each time an item is…

Critical action research emphasises participation, democracy and social critique, and thus has had considerable potential for feminist scholarship and action. Feminist action research, in turn, has gained a foothold in education, for example, through the work of Hollingsworth, Miller, Lather and others, although much action research might still be…

What types of instructional experiences help K-8 students learn science with understanding? What do science educators, teachers, teacher leaders, science specialists, professional development staff, curriculum designers, and school administrators need to know to create and support such experiences? "Ready, Set, Science!" guides the way with an…

The organizational dimension of participation is relevant to planning organizations as well as to service organizations. In this case the organizational output is not direct services but the production of specific plans and proposals. The objective of group participation is to establish plans which call for maximum benefits for a particular…

Due to conceptualizations of autonomy as detachment and independence, research on the parenting-autonomy relationship in adolescence has yielded inconsistent results. In the present study, self-determination is proposed as an alternative way of tapping into the construct of autonomy. An integrated model of the relationships between perceived…

This article reports on the third year of a three-year longitudinal investigation into six secondary students' understanding of optics at a secondary school level. In the third year of this investigation the students, who by now were in Year 12, underwent a teaching sequence that centred on the teaching and learning of physical optics and quantum…

This study investigated the feasibility of applying economic demand analysis (especially elasticity of demand) in marketing George Washington University off-campus degree programs. In the case under study, a supplemental budget request had to be submitted to meet expenses incurred by an unforeseen increase in demand for graduate and undergraduate…

This paper compares the results of different models of police intervention in child sexual abuse cases in New South Wales, Australia. Data suggest that specialist police units in which police manage the full investigation provide a more comprehensive service than those where the police response is fragmented among units within the police force.…

Method: Audio-taped…

This article describes the use of the book "Inchworm and a Half" to stimulate children's investigations in measurement and number. During a two-day lesson children used physical models and visual representations to develop measurement skills and explore equivalent relationships.

A new model for problem solving is broken down into four overlapping and interactive processes: Problem Posing, Problem Approach, Problem Solutions, and Communication. Figures illustrate the skills used in this new image of science problem solving, and a ninth-grade science investigation employing the processes is described. (LZ)

This study examined how high school seniors construct decision-making strategies for choosing a college to attend. To comprehend their decision-making strategies, we chose to examine this process through the theoretical lens of bounded rationality, which brings to light the complexity in constructing a college choice decision-making strategy…
