THE DYNAMICS OF LEARNING SCIENCE IN EVERYDAY CONTEXTS: A CASE STUDY OF EVERYDAY SCIENCE CLASS IN KOREA

With recognition of the importance of scientific literacy for the nation and yet the increasing students’ disinterest in science through school science curriculum, the Korea Science Foundation launched an innovative program called ‘Everyday Science Class (ESC)’ in partnership with universities and local government offices in 2003. In this work, we introduce the structure and dynamics of the ESC program in K-district through examining (1) how everyday contexts helped learners’ perceptions and attitudes toward science and (2) how the dynamics of learning environments effected learners’ learning process. We employed interviews and video recording of classes for data collection. To analyze the data, we used the process of thematic coding to understand the outcomes and effects of ESC program. The research findings showed that everyday context and a unique environment of learning with parents in the ESC program could bring forth learners’ understandings on the connection between science and their everyday lives and positive attitudes toward science learning. We also found that there were certain issues to be taken into account in terms of children’s cognitive development for further development.     

Assessing preschool number sense: skills demonstrated by children prior to school entry

Components of early number sense, as identified in two Delphi studies and in the number sense literature related to mathematics difficulties, were assessed for 176 children in preschools and childcare centres across one local government area in Sydney, Australia, using tasks or modifications of tasks reported in the number sense literature. In addition, the children’s receptive vocabulary was measured using The Peabody Picture Vocabulary Test (third edition) and math reasoning was measured using Woodcock‐Johnson III Tests of Achievement. Although the children demonstrated a broad range of skills, there were no significant differences between children attending childcare and preschools for any of the measures. However, boys performed significantly better than girls in quantitative concepts and girls performed better than boys in subitising. In discussing the data, a comparison is made of the skills demonstrated by children and skills that were highlighted in the two Delphi studies and in the early number sense literature as being essential components of number sense prior to school entry. Implications for kindergarten mathematics curricula and approaches to the teaching of early number skills are discussed.     

Rural women in development: Veil of invisibility, world of work

Over the last decade, evidence has been accumulating that the process of development has resulted more frequently in greater economic marginalization than benefits for poor rural women in much of the Third World. Yet recent efforts aimed at incorporating these poor non-urban women into development have been hampered by the “veil of invisibility” hiding their past and present conditions and contributions. This article formulates some hypotheses concerning female invisibility as well as productivity, and then contrasts the extant view of rural Third World women as relatively unproductive with (1) evidence drawn from evolutionary history, and (2) data from new micro-level and UN studies. The former indicates that women were the primary producers in most pre-agrarian human groups. The latter indicate that women continue to produce approximately half the world's food, although there is dramatic regional variation. The article concludes with an analysis of the statistical biases and stereotypes that obscure these contributions and briefly indicates the cost of this invisibility to the countries involved as well as to the women themselves.     

The histopathologic reliability of tissue taken from cadavers within the gross anatomy laboratory

The purpose of this study was to examine the histopathologic reliability of embalmed cadaveric tissue taken from the gross anatomy laboratory. Tissue samples from hearts, livers, lungs, and kidneys were collected after the medical students’ dissection course was completed. All of the cadavers were embalmed in a formalin‐based fixative solution. The tissue was processed, embedded in paraffin, sectioned at six micrometers, and stained with H&E. The microscope slides were evaluated by a board certified pathologist to determine whether the cellular components of the tissues were preserved at a high enough quality to allow for histopathologic diagnosis. There was a statistically significant relationship between ratings and organ groups. Across all organs, there was a smaller proportion of “poor” ratings. The lung group had the highest percentage of “poor” ratings (23.1%). The heart group had the least “poor” ratings (0.0%). The largest percentage of “satisfactory” ratings were in the lung group (52.8%), and the heart group contained the highest percentage of “good” ratings (58.5%) The lung group had the lowest percentage of “good” ratings (24.2%). These results indicate that heart tissue is more reliable than lung, kidney, or liver tissue when utilizing tissue from the gross anatomy laboratory for research and/or educational purposes. This information advises educators and researchers about the quality and histopathologic reliability of tissue samples obtained from the gross anatomy laboratory.
