The goal of this study was to investigate the timing of online homework completion and its effects on student performance. Data was collected from two large, first-semester general chemistry sections at a southwestern university. Specifically, this study aims to explore the link between when students complete their homework relative to the date the material was covered in lecture and student performance in that class. Topics covered in the study included VSEPR, Lewis structures, and molecular geometry. Performance was measured by different variables, namely in-class clicker scores (short-term) and exam grade (long-term). Students were divided into three groups: students who completed the relevant homework within 2 days after the lecture (before the next lecture), those who completed the homework 2 to 4 days after the lecture, and students who completed the homework more than 4 days after the material was covered in lecture. The study also took into consideration student reasoning abilities, as measured by the Test of Logical Thinking (TOLT), with a focus on at-risk students (low TOLT students). Results showed promising findings for low TOLT students. Instructors can employ results from this study to help their students better utilize the online homework resources.

The commentators on my target article (Bunge 2003) have pointed out some gapsand controversial points in it. However, we all agree that (a) although the quantum theory is basically correct, its orthodox or Copenhagen interpretation, particularly the claim that quantum events are mind-dependent, is false; and (b) quantons – the referents of the quantum theory – however strange, exist on their own, even if some of their properties depend partially upon their environment. I only differ from some of my commentators on whether the quantum theory has no precursors at all; on whether it can explain everything physical, including the universe as a whole; and on whether the quantum theory of measurement is relevant. In this collective reply I will (a) emphasize the peculiarities of quantons by contrast to classons, while at the same time rejecting the hypothesis of absolute novelty; (b) show why the standard quantum theory of measurement fails to explain how measuring devices work; and (c) state that quantum cosmology, which claims to know the state-vector of the universe, is so far just a fantasy. 相似文献
ABSTRACTThere are varied approaches that have been used in sport for development (SFD) projects. This article is focused on the move by sport and exercise psychology researchers toward community-based SFD projects where marginalized groups are centralized. The authors have chosen two of their projects to exemplify different approaches to SFD. An initial project with an Aboriginal community is critically examined to reveal cultural missteps that perpetuated cultural colonization–something antithetical to community capacity building. The second project is then considered because of its closer alignment with cultural praxis and community capacity building. This second project focuses on the initial developments of a YMCA physical activity project designed to meet the needs of forced immigrants (a self-titled name developed by the refugee community members) and the staff who work with them. We culminate with five postulates proposed for SFD project teams derived from our vantage in sport and exercise psychology, where community engagement and eventual self-governance are imperatives. 相似文献
This paper presents the results of a survey conducted among departmental resource centres in higher education. The survey aimed at quantifying, validating and supplementing information gathered through visits, case studies and the literature and was constructed around six areas: information about each center; details of the learning resources housed in them; an assessment of their use; feedback and evaluation activities; information about the staff in charge of centres; and finally a section on general comments made by respondents. 相似文献
CONTEXT: Of the approximately 900,000 children who were determined to be victims of abuse or neglect by US child protective services in 2002, the birth-to-3 age group had the highest rate of victimization (1.6%) and children younger than 1 accounted for the largest percentage of victims (9.6%). OBJECTIVE: To identify perinatal and sociodemographic risk factors associated with maltreatment of infants up to 1 year of age. DESIGN AND SETTING: Observational cohort study. PARTICIPANTS: 189,055 children born in 1996 in Florida. MAIN OUTCOME MEASURE: Infant maltreatment, defined as a verified report of abuse, neglect, or threatened harm that occurred between day 3 of life and 1 year. RESULTS: 1,602 children (.85%) of the 1996 birth cohort had verified instances of maltreatment by age 1. Of 15 perinatal and sociodemographic variables studied, 11 were found to be significantly related to infant maltreatment. Five factors had adjusted relative risks (RR) of two or greater: Mother smoked during pregnancy (RR 2.8); more than two siblings (RR 2.7); Medicaid beneficiary (RR 2.1); unmarried marital status (RR 2.0); low birth weight infant (RR 2.0). Infants who had four of these five risk factors had a maltreatment rate seven times higher than the population average. CONCLUSIONS: Data on nearly all risk factors found to be significantly associated with infant maltreatment are available on the birth certificate. Such information can be incorporated into a population-based risk-assessment tool that could identify subpopulations at highest risk for infant maltreatment. Because resources are limited, these groups should be given priority for enrollment in child abuse prevention programs. 相似文献
