Students who fail algebra are significantly less likely to graduate on time, and algebra failure rates are consistently high in urban districts. Identifying effective credit recovery strategies is critical for getting students back on track. Online courses are now widely used for credit recovery, yet there is no rigorous evidence about the relative efficacy of online versus face-to-face credit recovery courses. To address this gap, this study randomly assigned 1,224 ninth graders who failed algebra in 17 Chicago public high schools to take an online or face-to-face algebra credit recovery course. Compared to students in face-to-face credit recovery, students in online credit recovery reported that the course was more difficult, were less likely to recover credit, and scored lower on an algebra posttest. There were no statistically significant differences by condition on any outcomes measured during the second year of high school (standardized mathematics test and algebra subtest scores, likelihood of passing subsequent math classes, cumulative math credits, or on-track rates). The benefits and challenges of online learning for credit recovery are discussed in light of the findings to date. 相似文献

This article recounts the fight over public soundspace at Grand Central Terminal in 1949 after management began using Muzak, punctuated by commercial advertisements, to manage and monetize the soundscape. The public protests against these broadcasts in the press were followed by public hearings which weighed the commuter’s right to be left alone with his or her own thoughts against the company’s right broadcast sell the public soundspace. The author argue that this case, which was tied to a similar case before the Supreme Court, set a legal precedent allowing public soundspaces to be monetized in the same way as physical or visual spaces were, and set the stage for the ubiquitous engineering of public soundspaces that is the norm today. 相似文献

The pterygopalatine fossa (PPF) is a bilateral space deep within the skull that serves as a major neurovascular junction. However, its small volume and poor accessibility make it a difficult space to comprehend using two-dimensional illustrations and cadaveric dissections. A three-dimensional (3D) printed model of the PPF was developed as a visual and kinesthetic learning tool for completely visualizing the fossa, its boundaries, its communicating channels, and its neurovascular structures. The model was evaluated by analyzing student performance on pre- and post-quizzes and a student satisfaction survey based on the five-point Likert scale. The first cohort comprised of 88 students who had never before studied the PPF. The second cohort consisted of 30 students who were previously taught the PPF. Each cohort was randomly divided into a control group who were provided with a half skull and an intervention group that were provided with the 3D printed model. The intervention group performed significantly better on the post-quiz as compared to the control group in cohort I (P = 0.001); while not significant, it also improved learning in cohort II students (P = 0.124). Satisfaction surveys indicated that the intervention group found the 3D printed model to be significantly more useful (P < 0.05) as compared to the half skull used by the control group. Importantly, the effect sizes for cohorts I and II (0.504 and 0.581, respectively) validated the statistical results. Together, this study highlights the importance of 3D printed models as teaching tools in anatomy education. 相似文献

Effective force and economy of triathletes and cyclists 总被引:1,自引:0,他引:1

The effective force applied on the crank, the index of pedalling effectiveness, and the economy of movement at 60, 75, 90, and 105 rev/min cadences were examined in nine cyclists and eight triathletes. Tests were performed on two days. Maximal oxygen uptake was measured and the second ventilatory threshold was estimated on day 1 using a stationary bicycle. On day 2, the four different cadences were tested at about 5% below the second ventilatory threshold. A strain gauge instrumented clip-less pedal mounted on the bicycle enabled us to measure the normal and tangential forces exerted on the pedal, while the pedal and crank angles were monitored with the aid of a video system. Based on this information, the effective force and the index of pedalling effectiveness were calculated. Cyclists produced significantly more effective force and a higher index of pedalling effectiveness at 60 and 75 rev/min and were significantly more economic at all cadences than triathletes. The significant and positive correlation between effective force and economy at all cadences suggests that improvement of the effective force would reflect on economy. 相似文献

美国医学教育中的职业化问题:从证据到责任 总被引:4,自引:0,他引:4
职业化是维护公众对医学职业信任的核心要素,也是医患关系的本质所在.但有证据表明,公众对医学职业的信任日渐消失,医生也在维护医学职业价值观念时面临着各种挑战.本文在医学教育背景下界定"职业化"的定义和框架,描述了职业化面临的各种挑战,也详细论述了医学院校和教学医院在维护医学职业化过程中的角色和作用.此外,还评述了现行和试行中的评价职业化的工具、方法.最后,作者还提出一些建议供医学院校和教学医院参考. 相似文献

Abstract In this paper we synthesize elements of the modern philosophy and practice of organization management and leadership and illustrate their application to museums. The elements of our synthetic theory are a museum's inventory of processes (system of work), the role of its leader/director, and the social structures of the museum. These theoretical elements are placed in a conceptual context called the museum maturity framework, a five‐level developmental sequence in which are organized the paradigms and behaviors of a museum as it matures. The museum maturity framework can help the internal and external analysis and assessment of museums. 相似文献
