The extraordinary romance and thrilling adventure associated with the tale of wootz steel shows how Indian metallurgists were
the world leaders in antiquity in the manufacture of this legendary high-grade steel. In many ways this material was brought
to global attention by the writings of Cyril Stanley Smith. Modern metallurgy and materials science rest on the foundation
built by the study of this steel during the past three centuries. 相似文献

Pedro Gutiérrez Bueno wrote two editions of a chemistry textbook between 1788 and 1802. The paper offers a comparative view
of both editions taking into account Gutiérrez Bueno’s biography, his intended audience and the changes related to the so-called
chemical revolution. Some conclusions are at odds with common images about scientific revolutions and the role of textbooks
in science. The analysis aims to shed some light on the multiple historical forces shaping textbooks and the way in which
scientific change is assimilated by their writers.

Students learning to read in more than one language are a growing population in schools. Early screening and identification of reading difficulties may lead to better outcomes for all students. Oral reading fluency (ORF) is one tool shown to be both a reliable measure of reading and an accurate method to identify students at risk for poor reading outcomes. This study synthesized available validity evidence for ORF with biliterates. All included studies (n = 31) were conducted with English language learners in grades K–8. Results suggested that although ORF is correlated with reading outcomes, the accuracy of ORF to identify English learners at risk of poor reading outcomes does not meet criteria. The strength of validity evidence differed by language proficiency of participants. Finally, the quality of the reviewed studies was low in critical areas. 相似文献

In typical development, gestures precede and predict language development. This study examines the developmental sequence of expressive communication and relations between specific gestural and language milestones in toddlers with autism spectrum disorder (ASD), who demonstrate marked difficulty with gesture production and language. Communication skills across five stages (gestures, word approximations, first words, gesture-word combinations, and two-word combinations) were assessed monthly by blind raters for toddlers with ASD participating in an randomized control trial of parent-mediated treatment (N = 42, 12–30 months). Findings revealed that toddlers acquired skills following a reliable (vs. idiosyncratic) sequence and the majority of toddlers combined gestures with words before combining words in speech, but in contrast to the pattern observed in typical development, a significant subset acquired pointing after first words. 相似文献

The evaluation of faculty development programs 总被引:1,自引:0,他引:1
This article reviews literature pertinent to the evaluation of faculty development programs and presents data from several studies conducted at two institutions. These data were consistent with those previously reported in that faculty participants consistently expressed satisfaction with development services. In addition, one study found that most faculty members voluntarily took some action to improve their instructional effectiveness, though only a minority pursued these efforts in depth. Volunteers who worked intensively with a faculty development consultant improved more on objective measures of effectiveness than did those who were only superficially involved in improvement efforts; those who received no consultative assistance failed to improve significantly. Evidence from a final study provided a control for faculty motivation and led to the conclusion that improvement was contingent both on faculty desire to improve and on the availability of professional assistance. 相似文献
