This paper describes daily report cards and the evidence relating to their use in schools for children with attention‐deficit/hyperactivity disorder (ADHD). This intervention typically involves teachers evaluating a student's behaviour at school against pre‐determined targets and parents subsequently providing reinforcement at home for positive reports. Research suggests that the daily report card has been effective in treating a range of ADHD symptoms and improving school outcomes, including academic achievement in some cases. The daily report card also encourages collaboration between teachers and parents, and evidence suggests that the intervention benefits from the inclusion of reinforcement at home. Daily report cards are easy to implement and research finds that teachers consider them an acceptable intervention for ADHD. This paper also considers challenges in using daily report cards, including barriers to their use over the long‐term and the risk of stigma for children with a report card. Ideas to address these issues are suggested. 相似文献

Video market entry options available to telephone companies under the Telecommunications Act of 1996 have First Amendment implications that will affect the constitutional value of telephone video. These entry options impose regulatory constraints upon providers and differ in potentials for provider speech, speaker access, and content diversity. The author concludes that the Act's open video system option best advances First Amendment interests in increased diversity of and access to speech. 相似文献

This study presents a worked example of a stepped process to reliably estimate the habitual physical activity and sedentary time of a sample of young children. A total of 299 children (2.9 ± 0.6 years) were recruited. Outcome variables were daily minutes of total physical activity, sedentary time, moderate to vigorous physical activity and proportional values of each variable. In total, 282 (94%) provided 3 h of accelerometer data on ≥1 day and were included in a 6-step process: Step-1: determine minimum wear-time; Step-2: process 7-day-data; Step-3: determine the inclusion of a weekend day; Step-4: examine day-to-day variability; Step-5: calculate single day intraclass correlation (ICC) (2,1); Step-6: calculate number of days required to reach reliability. Following the process the results were, Step-1: 6 h was estimated as minimum wear-time of a standard day. Step-2: 98 (32%) children had ≥6 h wear on 7 days. Step-3: no differences were found between weekdays and weekend days (P ≥ 0.05). Step-4: no differences were found between day-to-day variability (P ≥ 0.05). Step-5: single day ICC’s (2,1) ranged from 0.48 (total physical activity and sedentary time) to 0.53 (proportion of moderate to vigorous physical activity). Step-6: to reach reliability (ICC = 0.7), 3 days were required for all outcomes. In conclusion following a 7 day wear protocol, ≥6 h on any 3 days was found to have acceptable reliability. The stepped-process offers researchers a method to derive sample-specific wear-time criterion. 相似文献

AbstractThe persistence of white privilege and escalating racism in the United States challenges religious educators to analyze the roots and destructive potential of both. This article draws on historical and contemporary analyses in dialogue with personal reflection and the oral histories of two leaders who seek to recognize and live beyond their own privilege. The purpose of the study is to describe the landscape of white privilege and analyze the intersections of public and personal dynamics. The analysis reveals the educational potential of personal narratives and structural analysis in understanding and transforming white privilege into humble work for justice. 相似文献

The present paper focuses on the application of a structured template, maximum impact flow (MIF), in order to encourage young students in the area of optics and optical engineering. MIF introduces a template in terms of individual steps and linked functionality and is shown to fuse separate learning tools together into a cohesive unit. Prioritization and teaching structures are also discussed with the promotion of technology identified as a key factor. 相似文献
