Summary While I enjoyed the concept of this product and felt that the questions were thought provoking, at $750 to get the base program
plus the 30 megabytes of hard disk space, I wish that the producers had concentrated less on flash and more on affordability.
The audio and video quality are impressive but not necessary. Students do not need all of the questions and answers read to
them. On that note, as a former classroom teacher, I had some concerns about the noise level. If you are going to invest in
this program, invest in some headphones. 相似文献

Summary Although the Internet is everyone’s darling, and plenty of dissection sites are available, not everyone has access. It is
not only conve nient but inexpensive to have a backup, in this case the BioLab Series on CD-ROM. It is a multi faceted product:
interactive and patient for students. Curricular integration and tracking for the teacher. Versatile since it can be used
as a self-tutorial and with a group. Let’s not forget the name less potential specimens that can be spared the diabolical
dissection by middle and high school stu dents raised on slasher movies. This series goes a long way in making science interesting,
chal lenging and very humane. 相似文献

Discussion and study of the social-emotional development of deaf and hard of hearing children, though extensive, has yet to provide an accurate understanding of the differences between deaf and hearing children. Consequently, the goal of the researchers was to conduct a profile analysis to determine similarities and differences between the two groups. The sample consisted of 20 hearing and 20 deaf children ages 8-11 years. All of the deaf children were enrolled in a Simultaneous Communication magnet program. Significant differences were found in two areas: school interest and on-task behavior. Overall, however, data from the study showed few differences between hearing and deaf children. The researchers recommend that current interventions be reconsidered on the basis of these results. 相似文献

Although school choice proponents have generally been on the offensive in legislative arenas over the past 2 decades, they have played almost constant defense in the judiciary, seeking to prevent courts from undoing school choice programs. Opponents typically wield state constitutional provisions against school choice programs. Properly construed, such provisions often are intended not to thwart but to secure educational opportunities. School choice supporters should consider taking the offensive, applying such provisions toward their intended ends by challenging defective schools and seeking meaningful remedies for children trapped in them. Choice remedy litigation can provide an effective complement to legislative efforts in the larger campaign to secure for disadvantaged children the precious educational opportunities that are their constitutional right. 相似文献

The purpose of this study was to evaluate the role of rotation axes during a tennis serve. A motion capture system was used to evaluate the contribution of the potential axes of rotation (minimum inertia axis, shoulder-centre of mass axis and the shoulder-elbow axis) during the four discrete tennis serve phases (loading, cocking, acceleration and follow through). Ten ranked athletes (International Tennis Number 1–3) repeatedly performed a flat service aiming at a target on the other side of the net. The four serve phases are distinct and thus, each movement phase seems to be organised around specific rotation axes. The results showed that the limbs’ rotational axis does not necessarily coincide with the minimum inertia axis across the cocking phase of the tennis serve. Even though individual serving strategies were exposed, all participants showed an effect due to the cocking phase and changed the rotation axis during the task. Taken together, the results showed that despite inter-individual differences, nine out of 10 participants changed the rotation axis towards the minimum inertia and/or the mass axis in an endeavour to maximise external rotation of the shoulder to optimally prepare for the acceleration phase. 相似文献
