Massive Online Open Courses (MOOCs) provide opportunities to learn a vast range of subjects. Because MOOCs are open to anyone with computer access and rarely have prerequisite requirements, the range of student backgrounds can be far more varied than in conventional classroom-based courses. Prior studies have shown that misconceptions have a huge impact on students' learning performance; however, no study has empirically examined the relationship between misconceptions and learning persistence. This study of 12,913 MOOC-takers examines how students' misconceptions about the upcoming course material affect course completion. Using a survival analysis approach, we found that, controlling for the score in a pre-course test, students holding more misconceptions had a higher dropout rate at the start of the course, an effect that diminished over time. Other student variables were found to have a positive impact on survival that persisted throughout the entire course: U.S. location, higher age, an intention to complete, better English skills, prior familiarity with the subject, motivation to earn a certificate, and score and time spent on the previous problem set (homework). By contrast, student gender, education level, number of previous MOOCs completed, and motivation to participate in online discussion forums did not affect survival. 相似文献
Science fiction remains an alien dimension of the history of science. Historical and literary studies of science have become increasingly attentive to various "literary technologies" in scientific practice, the metaphorical features of scientific discourse, and the impact of popular science writing on the social development of scientific knowledge. But the function of science fiction and even literature as such in the history of scientific and technological innovation has often been obscured, misconstrued, or repudiated owing to conventional notions of authorship, influence, and the organic unity of texts. The better to address those close encounters where scientific practice makes use of speculative fiction, this essay proposes that we instead analyze such exchanges as processes of appropriation, remixing, and modification. 相似文献
Background: Within NHS North West England there are 24 primary care trusts (PCTs), all with access to different types of library services. This study aims to evaluate the impact the type of library service has on online resource usage. Methodology: We conducted a large‐scale retrospective quantitative study across all PCT staff in NHS NW England using Athens sessions log data. We studied the Athens log usage of 30 381 staff, with 8273 active Athens accounts and 100 599 sessions from 1 January 2007 to 31 December 2007. Results: In 2007, PCTs with outreach librarians achieved 43% penetration of staff with active Athens accounts compared with PCTs with their own library service (28.23%); PCTs with service level agreements (SLAs) with acute hospital library services (22.5%) and with no library service (19.68%). This pattern was also observed when we looked at the average number of Athens user sessions per person, and usage of Dialog Datastar databases and Proquest full text journal collections. Discussion: Our findings have shown a correlation of e‐resource usage and type of library service. Outreach librarians have proved to be an efficient model for promoting and driving up resources usage. PCTs with no library service have shown the lowest level of resource usage. 相似文献
ABSTRACT: This paper argues that the introduction of access agreements following the establishment of the Office for Fair Access (OFFA) has consolidated how English higher education institutions (HEIs) position themselves in the marketplace in relation to widening participation. However, the absence of a national bursary scheme has led to obfuscation rather than clarification from the perspective of the consumer. This paper analyses OFFA's 2008 monitoring report and a sample of twenty HEIs' original 2006 and revised or updated access agreements (2008) to draw conclusions about the impact of these agreements on notions of 'fair access' and widening participation. The authors conclude that, unsurprisingly in an increasingly market-driven system, institutions use access agreements primarily to promote enrolment to their own programmes rather than to promote system-wide objectives. As a consequence of this marketing focus, previous differences between pre-1992 and post-1992 institutions in relation to widening participation and fair access are perpetuated, leading to both confusion for consumers and an inequitable distribution of bursary and other support mechanisms for the poorest applicants to HE. 相似文献
In this article we explore the level of job satisfaction and the sources of job dissatisfaction for 210 secondary school teachers in southwest England and compare our results with the results from a similar study published in 1962. Using anonymous questionnaires, we asked 210 secondary teachers in southwest England (63% female) to rate their level of job satisfaction and to rate 16 sources of job dissatisfaction that we adapted from the 1962 study. Teachers in 2007 rated their job satisfaction significantly lower and ordered the sources of job dissatisfaction significantly differently than did teachers in 1962. Whereas teachers in 1962 were most concerned with external sources of job dissatisfaction (e.g. salary, condition of buildings and equipment and poor human relations), teachers in 2007 expressed the most concern about factors relating to teaching itself (e.g. time demands and pupils' behaviour). The changes in sources of dissatisfaction hold true for male and female teachers, with no difference in rankings according to years of teaching experience. 相似文献
The paper explores challenges for the interpretation of the ideal toleration that arise in educational contexts involving children. It offers an account of how a respect-based conception of toleration can help to resolve controversies about the accommodation and response to diversity that arise in schools. 相似文献
Increases in the number of college students seeking mental health services require counseling centers to explore innovative strategies to provide effective and efficient treatments. Group interventions offer an alternative to traditional individual counseling, allowing centers to serve more students with fewer clinical staff (Burlingame et al., 2016). Of current group modalities, mindfulness-based interventions (MBIs) have been growing in popularity as an effective approach for addressing college students’ increasingly complex needs. This study describes the evaluation of a three-session mindfulness-based intervention on students’ mindfulness, symptoms, and stress. Compared to a comparison group of 109 students not seeking counseling center services, 78 students who received the intervention reported increased mindfulness, and decreased symptoms of depression, anxiety, and stress at the end of the group. Furthermore, improvements in mindfulness mediated intervention effects on symptoms of depression and anxiety. These gains were generally maintained 3 weeks later. These findings support the benefits of brief group interventions for college students. Suggestions for modifications to the intervention and for future research are discussed. 相似文献
This paper suggests a particular value to treating the teaching of poetry in school comparatively. It argues that the justification for this claim derives from the ways in which peculiar symbiotic dependencies between poetry, languages, cultures and uniquely individual consciousness‐‐and between poetry, childhood learning and children's achievement of literacy‐‐can be represented in a teaching methodology. It refers to a unique teaching and research project, directed by the author at Goldsmiths’ College, University of London, which has developed principles and strategies for building a new pedagogy with children and in teacher education.相似文献
Many studies have shown that Newton's Third Law of Motion is not easy for students to accept when they consider the interaction
of two objects. A number of prominent science educators believe that it should not be taught to students before Year 11. This
paper reports the results of a study of the historical origins of Newton's Third Law with a view to identifying the context
from which it emerged in the 17th century and the conceptual changes which accompanied its emergence. Some of the possible
implications of a study such as this for improving the teaching of introductory mechanics are discussed.
