This research study presents the PGBE model for teaching and learning percentages with students of Grade 7 when their cognitive development enables the conceptual understanding of percentages as proportional statements, and offers the possibility for more effective matching of them with fractions and decimal numbers. The abbreviation PGBE presents…

This review uses research literature to outline the characteristics, benefits and disadvantages of formal, non-formal, and informal learning. There appears to be a consensus around the meanings of formal and informal learning. Formal learning broadly aligns with organised, institutionalised learning models (such as learning seen in schools),…

The aim of the present study was to gain an insight into French young people's conceptual development regarding the greenhouse effect. Because this effect cannot be directly manipulated, we can assume that its conceptualization is mainly shaped through the sharing of information. Eighty French students from Grade Seven through to adulthood…

Suppose you are presented with 2 informants who have provided answers to the same question. One provides a precise and confident answer, and the other says that they do not know. If you were asked which of these 2 informants was more of an expert, intuitively you would select the informant who provided the certain answer over the ignorant…

Many science educators are concerned with students' ability to understand science as a process and with their conceptions of scientific knowledge. Preliminary work has shown that the use of a model organizer can result in student perceptions of improved understanding, but the reason for this effect is not known. This research was undertaken to…

Kindergarten (n=30) and grade 1 (n=15) students of contrasting socioeconomic backgrounds were interviewed to assess their knowledge of number word sequences and spatial patterns and their ability to recognize numerals and use counting to establish numerosity of visible and screened collections. Findings indicate greater variation in abilities…

Researchers from BBN Laboratories and Lesley College (Massachusetts) have begun exploratory studies to build an understanding of the learning that occurs when middle school students interact with science-based simulations. Sixty hours of discussion among eight middle school students were videotaped as they used the simulations from the…

A broad range of research efforts are currently examining the quality and nature of the mathematics instructional program in the early grades. The purpose of this paper was to report on the assessment of a teaching-learning program in grade one classrooms. The major goals of the study were to: (1) identify patterns and change in children's…
