A psychometric evaluation of the Bicycle drawing test and the establishment of preliminary norms

The main purpose of this study was to examine the psychometric characteristics of the Bicycle Drawing Test. The 20-point scoring criterion was evaluated, and the preliminary norms were established. The Bicycle Drawing Test is an easily administered free-style drawing task that has been found to be a useful addition to a neuropsychological test battery. It provides a sample of visuopractic functioning involving the formation of a perceptual construct, a motor response, and a spatial component

A Cross-Age Study of Students\u27 Knowledge of Insect Metamorphosis: Insights Into Their Understanding of Evolution.

Insect metamorphosis is relatively easy to explain at a superficial level, but a deep understanding of the concept reveals a complex array of interrelationships, most importantly those that address evolution. This is significant because, in biology, evolution is considered to be a central theme. Participants for this study were selected from grades 5, 7, 9, and 11 according to low, middle, or high achievement levels in their science classes, and to scores on a national achievement test. The research incorporated a three-level response strategy in order to ascertain more completely students\u27 knowledge of insect metamorphosis, and to better suggest how that knowledge could give insight into their understanding of evolution. First, a series of scientifically accurate line drawings depicting grasshopper and butterfly metamorphic stages probed understanding of basic concepts. Second, concept circle diagrams identified and explored students\u27 concept clusters involving insect metamorphosis. Third, clinical interviews involving direct observation of insect metamorphosis in vivo assessed the degree of integration of two clusters of insect metamorphosis concepts; metamorphic and evolutionary. In formulating this study\u27s research questions, the theoretical bases of prescientific conceptions and meaningful learning, as well as histories of science and entomological literature were accessed. Specific questions addressed by this research were: (1) What major alternative conceptions do students hold concerning insect metamorphosis? (2) How does students\u27 understanding of insect metamorphosis change across grade levels? (3) Are students able to give evolutionary explanations for insect metamorphosis? The major alternative conceptions of public school students taking part in this study about insect metamorphosis fell into five major categories: visual stage recognition, stage terminology, characteristics of stages, factors influencing insect metamorphosis, and types of metamorphosis. No increase in student understanding of insect metamorphosis across grade levels was evidenced from the stage picture data. The concept circle diagram data, however, showed an increase in understanding from grade five to grade eleven. The vast majority of the students were unable to give an evolutionary explanation for insect metamorphosis. Findings suggest that direct entomological experiences may increase pupils\u27 understanding of both insect metamorphosis and evolution

The Power Of Play In Early Childhood Education

This literature review synthesizes research on how early childhood classrooms use play as a learning tool for students. The review of literature examines different types of play and how children develop in relation to play. Play in the classroom is often viewed as a reward for completing schoolwork, but in preschool classrooms and beyond, play offers a wide variety of learning opportunities and aids in the development of new skills. This literature review uses scholarly articles and journals to examine the different types of early childhood play in the classroom and how children develop in relation to being able to play. Research published within the last ten years on the topic of play in the classroom reveals evidence that children are in fact learning while participating in play

Unsaturated Flow and Transport of \u3csup\u3e90\u3c/sup\u3eSr, Co(II)EDTA, and U(VI) in Undisturbed Cores from the Hanford formation, Hanford, WA

At the U.S. Department of Energy’s Hanford Site in Richland, WA nuclear processing wastes, such as Sr-90, organic chelating agents such as EDTA, Co-60, and U(VI) have been detected in the vadose zone beneath the underground storage tanks. There is concern that waste released to the vadose zone could reach the groundwater and eventually flow into the Columbia River. The goal of this paper is to provide an improved understanding of coupled hydrologic and geochemical mechanisms that influence contaminant transport in the Handford vadose zone. Disturbed sediment and undisturbed sediment cores were collected from the Environmental Restoration Disposal Facility (ERDF) at the Handford Site. The disturbed sediment was used in batch sorption experiments as well as saturated repacked column experiments. The undisturbed cores were collected vertically (flow across bedding) and horizontally (flow along bedding) to determine the effect of bedding on fate and transport of contaminants over a range of moisture contents. Multiple non-reactive tracers were used to quantify physical non-equilibrium processes such as preferential flow and media bypass as well as diffusion into immobile water. Miscible displacement experiments were conducted with Sr+2, Co(II)EDTA and U(VI) to quantify the importance of hydrologic processes on the geochemical reactions. Unsaturated undisturbed core experiments indicate the prevalence of unsaturated lateral flow while vertical flow is inhibited due to capillary barriers that develop in the coarse-grain sediment beds resulting in minor perching. During unsaturated lateral flow at low water content, multiple flow paths can develop which may limit the surface sites available for geochemical interactions and therefore “accelerate” transport compared to that predicted from commonly used batch or saturated packed column experiments. The results indicated that sedimentary bedding controls the flow paths (i.e., the hydrology), which then affects the geochemical processes. These coupled processes appear to significantly affect transport in the Hanford vadose zone and need to be considered in the development of conceptual models of vadose zone transport in arid environments

Observations on the Pollination of Some of the Compositae

The brilliant appearance of our western roadsides and prairies from July to October, invites an extended study of the anatomy and physiology of the Compositae. The wide distribution and rapid increase of this family naturally call attention to dissemination and pollination. Darwin, Herman Mueller, and others, have shown at length, the direct relation between special adaptations for cross-pollination and the race stability of plants. The question now arises, what are the opportunities for cross-pollination in Compositae, and to what extent is this agent a factor on the increase and distribution of the family? No attempt is here made to go into a discussion in full of these questions for the entire Family, but simply to present a few facts relative thereto, gathered from representatives of the subtribes Heliantheae and Asterineae

Man\u27s Physical Effects on the Elizabeth RIver

Man\u27s ever increasing activities in the Elizabeth River, i.e. dredging, disposal of dredged material and waterfront development, have drastically altered the river floor, reshaped the shoreline and changed the circulation. Long-continued dredging of shipping channels, which is fostered by coal export, larger ships, and military needs, has moved 220 million cu yds of sediment since 1870. As a result channel depth has increased 1.8 fold, and maintenance dredging rates have doubled about every 35 years. Open water disposal released 40 million cu yds into Hampton Roads and lower Chesapeake Bay. Landfill buried tributary creeks, moved the waterfront into the river and reduced the river area by 27%. As a consequence of reduced area and greater channel depth, current velocity has diminished and near-bottom salinity likely increased. These conditions induce faster sedimentation that in turn, creates a need for greater maintenance dredging and hence, greater disposal. The dredge and fill cycle, therefore, is self-perpetuating. The long-term trends of channel deepening, enlargement, and landfill, are expected to continue in response to larger ships, military needs and projected sea-level rise.https://scholarworks.wm.edu/vimsbooks/1155/thumbnail.jp
