Early research experiences must be made available to all undergraduate students, including those at 2-yr institutions who account for nearly half of America''s college students. We report on barriers unique to 2-yr institutions that preclude the success of an early course-based undergraduate research experience (CURE). Using a randomized study design, we evaluated a CURE in equivalent introductory biology courses at a 4-yr institution and a 2-yr institution within the same geographic region. We found that these student populations developed dramatically different impressions of the experience. Students at the 4-yr institution enjoyed the CURE significantly more than the traditional labs. However, students at the 2-yr institution enjoyed the traditional labs significantly more, even though the CURE successfully produced targeted learning gains. On the basis of course evaluations, we enhanced instructor, student, and support staff training and reevaluated this CURE at a different campus of the same 2-yr institution. This time, the students reported that they enjoyed the research experience significantly more than the traditional labs. We conclude that early research experiences can succeed at 2-yr institutions, provided that a comprehensive implementation strategy targeting instructor, student, and support staff training is in place. 相似文献

This paper summarizes the outcomes of a retreat designed to cultivate interactions between trainees at various training levels and provide them opportunities to share their training perspectives and expectations. Retreat outcomes are used to support the development of better science, technology, engineering, and mathematics training practices by informing the trainers’ perspective. 相似文献

Informal environments provide students with unique experiences that allow them to actively participate in activities while promoting a positive attitude toward and an increased interest in science. One way to enhance informal science experiences is through the integration of mobile technologies. This integration is particularly useful in engaging underrepresented students in learning science. Our informal environmental science program engages underrepresented, fifth-grade students in an informal learning environment supplemented with mobile tablet technology (iPads). The purpose of this study was to explore how fifth-grade students interacted with nature using mobile technology during a nature hike series. Participants included 55 fifth-grade students from two low-income schools. We found that students used the mobile technology to explore nature and stay engaged throughout the hike. The iPads were used as references, data collectors, and engagement tools. Students had an intense desire in returning to the site and responded positively toward interacting with nature. Prior research has indicated that students in this age group are likely to lose interest in science and the incorporation of field-friendly technology that engages students with nature, not technology alone, is a useful tool for keeping students interested in science. 相似文献

Scotland, traditionally, has high levels of confidence in teachers. Fairness and justice are key concepts in policy and practice in Scottish education. For more than 100 years, the high-stakes assessment system in Scotland, with the Scottish Higher qualification at its heart, has been crucial to that sense of opportunity and justice. However, in 2019–2020, public confidence in high-stakes assessment in Scotland, as in other United Kingdom countries, was dented. In Scotland, the Covid-19 pandemic meant that schools were closed, teachers provided online learning opportunities for pupils working at home and, for the first time in 130 years, it was not possible to run national examinations. To ensure that learners were not further disadvantaged, alternative approaches to gathering evidence for qualifications were instigated. However, these results were challenged as socially unjust and the results that had been nationally moderated were replaced by results based on locally moderated teachers' professional judgement. As Scotland looks to qualifications beyond Covid-19, trust must be re-built. This article reports on a participative research project that sought to understand public perceptions of standards and fairness across a range of key communities following this experience. Drawing on both qualitative and quantitative data, we analyse factors which affected trust in National Qualifications under the pandemic. The evidence suggests that when considering what matters for qualifications to be trusted, technocratic solutions are likely to be rejected by stakeholders. Understanding and responding to what led to the mistrust of qualifications in Scotland will be crucial to inform its future qualifications system. 相似文献

Mobile banking (mBanking) enables customers to carry out their banking tasks via mobile devices. We advance the extant body of knowledge about mBanking adoption by proposing a model for understanding the importance and relationship between the user perception of mBanking, initial trust in mBanking services, and the fit between the technology and mBanking task characteristics. We synergistically combine the strengths of three IS theories – task technology fit (TTF) model, unified theory of acceptance and usage of technology (UTAUT), and initial trust model (ITM). The model was tested in a study conducted in Portugal, one of the European Union (EU) countries with the highest mobile phone adoption. Based on the sample of 194 individuals we applied partial least squares (PLS) to test the conceptual model propose. The path significance levels were estimated using the bootstrapping method (500 resamples). The study found that facilitating conditions and behavioral intentions directly influence mBanking adoption. Initial trust, performance expectancy, technology characteristics, and task technology fit have total effect on behavioral intention. The paper offers valuable insights to decision-makers involved in the implementation and deployment of mBanking services. For researchers, the paper highlights the usefulness of integrating TTF, UTAUT and ITM in the development of a decision support framework to study the adoption of new technologies. 相似文献

<正>"I participated within the CAS/MPG cooperation in the introduction of Independent Junior Research Groups at institutes of the CAS.This activity is among the most delightful and successful experiences of my scientific life.The establishment of this scientific instrument in China was determined by its scientific success in the MPG–constantly underlined by Uli Schwarz–and the groundbreaking readiness of the leadership of the CAS to pursue novel avenues of scientific organisation. 相似文献

Organization of airway epithelium determines ciliary beat direction and coordination for proper mucociliary clearance. Fluidic shear stresses have the potential to influence ciliary organization. Here, an in vitro fluidic flow system was developed for inducing long-term airflow shear stresses on airway epithelium with a view to influencing epithelial organization. Our system consists of a fluidic device for cell culture, integrated into a humidified airflow circuit. The fluidic device has a modular design and is made from a combination of polystyrene and adhesive components incorporated into a 6-well filter membrane insert. We demonstrate the system operates within physiologically relevant shear and pressure ranges and estimate the shear stress exerted on the epithelial cell layer as a result of air flow using a computational model. For both the bronchial epithelial cell line BEAS2B and primary human tracheal airway epithelial cells, we demonstrate that cells remain viable within the device when exposed to airflow for 24 h and that normal differentiation and cilia formation occurs. Furthermore, we demonstrate the utility of our device for exploring the impact of exposing cells to airflow: our tool enables quantification of cytoskeletal organization, and is compatible with in situ bead assays to assess the orientation of cilia beating. 相似文献
