We investigated some of the key features of effective active learning by comparing the outcomes of three different methods of implementing active-learning exercises in a majors introductory biology course. Students completed activities in one of three treatments: discussion, writing, and discussion + writing. Treatments were rotated weekly between three sections taught by three different instructors in a full factorial design. The data set was analyzed by generalized linear mixed-effect models with three independent variables: student aptitude, treatment, and instructor, and three dependent (assessment) variables: change in score on pre- and postactivity clicker questions, and coding scores on in-class writing and exam essays. All independent variables had significant effects on student performance for at least one of the dependent variables. Students with higher aptitude scored higher on all assessments. Student scores were higher on exam essay questions when the activity was implemented with a writing component compared with peer discussion only. There was a significant effect of instructor, with instructors showing different degrees of effectiveness with active-learning techniques. We suggest that individual writing should be implemented as part of active learning whenever possible and that instructors may need training and practice to become effective with active learning. 相似文献

The present work describes the operation and simulation of a microfluidic laminar-flow mixer. Diffusive mixing takes place between a core solution containing lipids in ethanol and a sheath solution containing aqueous buffer, leading to self assembly of liposomes. Present device architecture hydrodynamically focuses the lipid solution into a cylindrical core positioned at the center of a microfluidic channel of 125 × 125-μm2 cross-section. Use of the device produces liposomes in the size range of 100–300 nm, with larger liposomes forming at greater ionic strength in the sheath solution and at lower lipid concentration in the core solution. Finite element simulations compute the concentration distributions of solutes at axial distances of greater than 100 channel widths. These simulations reduce computation time and enable computation at long axial distances by utilizing long hexahedral elements in the axial flow region and fine tetrahedral elements in the hydrodynamic focusing region. Present meshing technique is generally useful for simulation of long microfluidic channels and is fully implementable using comsol Multiphysics. Confocal microscopy provides experimental validation of the simulations using fluorescent solutions containing fluorescein or enhanced green fluorescent protein. 相似文献

Understanding what influences an individual to transition from awareness that a sport team exists to attraction to that team is of critical importance in the management and development of consumer bases. Determining the factors that prevent individuals at a stage of awareness from becoming attracted is of equal importance. In this paper we use a social identity approach to explore reasons for non-attendance. Qualitative data were gathered from a mixed-method online survey administered to registered participants in a large football (soccer) association in New South Wales. The questionnaire included an open-ended question allowing individuals who had not attended a match during the previous 12 months to elaborate on the reasons that they did not attend. The seventy-five individuals who responded to this open-ended question comprise the sample for this research. Data highlighted that cognitive apathy and disidentification were both salient cognitive responses associated with individuals who did not attend. Furthermore, club values and characteristics were shown to influence team-based perceptions. The findings present implications for sport teams to overcome cognitive apathy and disidentification through organisation-initiated efforts to disseminate information and promote the team, as well as efforts to align team characteristics and values with consumer perceptions. 相似文献

For many deaf and hard-of-hearing students, access to the general education curriculum is provided, in part, by using the services of an educational interpreter. Even with a highly qualified interpreter, full access to the content and social life in a hearing classroom can be challenging, and there are many aspects of the educational placement that can affect success. The skills and knowledge of the educational interpreter are one critical aspect. This study reports results from a study of approximately 2,100 educational interpreters from across the United States. All the interpreters were evaluated using the Educational Interpreters Performance Assessment (EIPA), an evaluation instrument used to assess and certify classroom interpreters (see Schick, Williams, & Bolster, 1999). The results show that approximately 60% of the interpreters evaluated had inadequate skills to provide full access. In addition, educational interpreters who had completed an Interpreter Training Program had EIPA scores only .5 of an EIPA level above those who had not, on average. Demographic data and its relationship with EIPA ratings are explored. In general, the study suggests that many deaf and hard-of-hearing students receive interpreting services that will seriously hinder reasonable access to the classroom curriculum and social interaction. 相似文献

Partnerships with parents, particularly in the field of education, have featured prominently in policy rhetoric for many years, but routes of redress have not had much attention until relatively recently. The development of Alternative Dispute Resolution in the UK reflects the situation in several jurisdictions (e.g. Norway, Germany, the Netherlands) where citizens can choose not to go to court to resolve administrative disputes. Under the Education (Additional Support for Learning [ASL]) (Scotland) Act 2004 local authorities must establish and publicise procedures for identifying and meeting the needs of children requiring additional support for learning. The Act and Code of Practice advocate early intervention to prevent disagreements about the provision for additional support from escalating into more serious disputes, with local authorities required to provide information about, and access to, independent mediation for parents. In Scotland the ASL Act 2004 has resulted in four routes available for redress in the area of Additional Support Needs which include both mediation and litigation type processes: ? Informal mediation ? Formal mediation ? Adjudication ? Tribunal This article uses case study information from parents in three local authorities in Scotland to explore why independent mediation is being under-used by schools and parents, and what factors influence this. Questions are raised regarding the large numbers of parents who are unaware of mediation, the attitudes towards and use of independent mediation by local authorities and the suitability of independent mediation, particularly when the dispute is over resources. 相似文献

Partnership evaluation typically occurs during the final stages either to assess why a collaborative effort did not work or to identify the indicators of success. Partnerships are rarely evaluated at their incipient stage, which is a critical time to assess their potential for long-term sustainability. In this paper, we present an early-stage evaluative framework for assessing multi-institutional academic partnerships’ sustainability based on 3 dimensions: decision processes, problem orientation, and social capital. We apply the evaluative framework using case study research to the Renewable Energy Assessment (REA) Program, a workforce enhancement academic partnership that focuses on facilities and lands viability assessment. Using the evaluative framework, we identified critical elements present within and missing from the REA Program that could influence the partnership's long-term sustainability. This study demonstrates the need to conduct incipient stage and ongoing evaluations to foster partnership sustainability, and provides a framework for conducting such assessments. 相似文献
