One wrong assumption about reality is sufficient to ensure the failure of education policy. For a variety of reasons, too many people have ignored realities in policies such as the No Child Left Behind Act. Individuals who are serious about reforming or improving education, general or special, must confront realities in at least the following areas: measurement, statistical distributions, measurement error, labels, special services, teacher responsibilities, and teacher training. Enacting or supporting education policy that is known to be seriously flawed is unacceptable and tantamount to the criminal conduct of someone who markets goods with known safety defects or harmful effects or of someone who ignores critical realities in the conduct of business. 相似文献

The civil rights movements involving skin tone, gender or gender orientation, disability, and other physiognomic features remain important in securing the legal rights of individuals to equal treatment and equal opportunities regardless of their personal characteristics of color, origin, gender, and so on. Unfortunately, these welcome civil rights movements have led to a misunderstanding of unfairness in another group of individuals whose rights and opportunities have often been abridged—students with disabilities. Individual rights and opportunities must be insured, but doing so requires the discrimination of differences among differences. That is, not all differences require the same remedy to insure equal rights and opportunities. Misunderstanding of differences and their implications have led to political concerns about disproportional representation, particularly of students with emotional or behavioral disorders, which place unwarranted constraints on special education services. 相似文献

Moving clients past counterproductive approaches to improving performance requires performance improvement (PI) professionals to work differently. They must collaboratively engage clients in anticipating and solving problems. It calls for a user‐friendly and explicit PI process that drives results. This proactive engagement promotes a shared view and language of the PI process. It enables PI professionals and clients to work jointly with common tools to improve performance, make everyday decisions, and achieve business results. 相似文献

The present research examined the influence of prior knowledge on children’s free recall, cued recall, recognition memory, and source memory judgments for a series of similar real‐life events. Forty children (5–12 years old) attended 4 thematic birthday parties and were later interviewed about the events that transpired during the parties using the National Institute of Child Health and Human Development protocol. Of the events, half were generic in that they could have occurred at any birthday party, and half were specific to the theme of the party. Older children demonstrated more evidence of using gist‐based information to guide their memory performance than did younger children. However, younger children were able to use global gist to inform their source memory judgments, qualifying past word‐learning research. 相似文献

The study compared the agreement, internal consistency, and measurement stability of the GE iDXA, BOD POD, and InBody 720. Body composition of 43 men and 37 women (31.4 ± 10.7 years; 90% Caucasian and 10% other) was assessed in triplicate using each method over two different days. Mean percent body fat (% BF) of the participants was different for all three machines (27.6 ± 10.0% [GE iDXA)] 25.6 ± 10.4% [BOD POD], and 21.3 ± 10.6% [InBody 720]; p < .05). The coefficient of variation for same day repeated measures was 1.06% (GE iDXA), 3.29% (BOD POD), and 2.97% (InBody 720). The coefficient of variation for 2-day repeated measures was 1.81% (GE iDXA), 4.61% (BOD POD), and 4.24% (InBody 720). The difference between the GE iDXA and BOD POD was within acceptable variability, while the InBody 720 significantly underestimated % BF. The internal consistency was highest for the GE iDXA, followed by the InBody 720, and then the BOD POD. 相似文献

The implications of teen sexting for healthy development continue to concern parents, academics, and the general public. Using a probability sample of high school students (N = 1,208) aged 12–18, the prevalence of sexting, associations with sexting, and associations between sexing and sexual activity were assessed. Seventeen percent both sent and received sexts, and 24% only received sexts. Sending and receiving sexts were positively associated with each other and both behaviors were associated with having peers who sext. Lifetime reports of sexual intercourse, anal sex, oral sex, and recent unprotected sex were positively associated with reports of texting 300 or more times per day, only receiving sexts, and both sending and receiving sexts. 相似文献
