Achievement of English as New Language Learners in Monitor Status: A Cross Sector Comparison from Denver

This study uses administrative data to measure the effect of attending a charter school in Denver, Colorado on the achievement of reclassified English as New Language (ENL) students during their monitor period in the mainstream classroom environment. We utilize school choice data from Denver’s Common Enrollment System (CES) to control for each school a family selected entering grade six, a typical time for a structural move, in order to better control of unobserved variable bias. Results indicate charter attendance increases achievement in mathematics and English on state testing. Charter school success in the CES environment provides insights for districts serving large numbers of ENL students.     

Sardonic science? The resistance to more humanistic forms of science education

Resistance to more humanistic forms of science education is an endemic and persistent feature of university scientists as well as school science teachers. This article argues that science education researchers should pay more attention to its origins and to the subtleties of its stubborn influence. The paper explores some of the imperatives which dominate the continuing practices of teachers; the linkages between school and university science; and re-considers the relationships between learning science, learning to do science and learning about science. It draws on recent, prominent publications, as well as neglected and rather more contentious material, to underline the unhelpfully narrow view of science held by those who defend the traditional disciplinary influences of biology, chemistry and physics. Suggestions are made as to where those of a more radical and determined disposition should direct their attention in the interests of improved education, vital scientific progress as well as human survival. It is argued that university science must change in order to ensure that teachers better help their students to learn, do and appreciate science.     

Ground reaction forces and kinematics of plant leg position during instep kicking in male and female collegiate soccer players

The players' ability to achieve the greatest distance in kicking is determined by their efficiency in transferring kinetic energy from the body to the ball. The purpose of this study was to compare the kinetics and kinematics of the plant leg position between male and female collegiate soccer players during instep kicking. Twenty-three soccer players (11 males and 12 females) were filmed in both the sagittal and posterior views while performing a maximal instep kick. Plant leg kinetic data were also collected using an AMTI 1000 force platform. There were no significant differences between the sexes in plant leg position, but females had significantly greater trunk lean, plant leg angle, and medial-lateral ground reaction force than the males. Males showed higher vertical ground reaction forces at ball contact, but there were no significant differences in ball speed at take-off between the sexes. Ball speed at take-off was inversely related to peak anterior-posterior ground reaction force (-0.65). The anatomical differences between the sexes were reflected in greater trunk lean and lower leg angle in the females.
