Although there has been a great deal of research into Collaborative Information Retrieval (CIR) and Collaborative Information Seeking (CIS), the majority has assumed that team members have the same level of unrestricted access to underlying information. However, observations from different domains (e.g. healthcare, business, etc.) have suggested that collaboration sometimes involves people with differing levels of access to underlying information. This type of scenario has been referred to as Multi-Level Collaborative Information Retrieval (MLCIR). To the best of our knowledge, no studies have been conducted to investigate the effect of awareness, an existing CIR/CIS concept, on MLCIR. To address this gap in current knowledge, we conducted two separate user studies using a total of 5 different collaborative search interfaces and 3 information access scenarios. A number of Information Retrieval (IR), CIS and CIR evaluation metrics, as well as questionnaires were used to compare the interfaces. Design interviews were also conducted after evaluations to obtain qualitative feedback from participants. Results suggested that query properties such as time spent on query, query popularity and query effectiveness could allow users to obtain information about team's search performance and implicitly suggest better queries without disclosing sensitive data. Besides, having access to a history of intersecting viewed, relevant and bookmarked documents could provide similar positive effect as query properties. Also, it was found that being able to easily identify different team members and their actions is important for users in MLCIR. Based on our findings, we provide important design recommendations to help develop new CIR and MLCIR interfaces.  相似文献

This study investigates the information needs of faculty and graduate students in agricultural and biological sciences. Qualitative research methods, interviews and focus groups, were used to examine what types of information these scholars need for their research, teaching and learning, how they seek that information, and perceptions. The implications for library service are discussed.  相似文献

This single-case meta-analysis is the first to provide a quantitative synthesis of the published literature on mathematics word problem-solving intervention studies for English learners with learning disabilities and mathematics difficulties. A total of ten single-subject studies were included for analysis. The current study investigated the magnitude of the effect of mathematics interventions targeting the improvement of students’ mathematics word problem-solving performance, and analyzed variables that moderated this effect. Results indicate a moderate overall effect size of 0.81 (95% CI [0.71, 0.90]) on word problem-solving performance for English learners with learning disabilities and mathematics difficulties. Moderator variables such as the implementer of the interventions, instructional focus, and word problem-solving content significantly moderated the mathematics intervention effects.  相似文献

This paper presents a comparative research study as a model for assessing undergraduate education. This evaluation model used Factor Analysis to create scales, tested the reliability of these scales, and used Analysis of Variance to compare the primary institution with five types of comparable institutions. The value of this statistical/methodological evaluation model was shown. Results are based on Class of l998survey responses from 244 graduating seniors at the primary institution and 1481 students at 39peer institutions. Comparative analyses identified business courses, faculty, career preparation and impact on students’ technological skill as strengths and students’ knowledge of arts and foreign languages and campus social life as areas for improvement at the primary institution. Recommendations advocated publicising students’ superior satisfaction with courses, faculty and career preparation; using these results as baseline data for future curriculum evaluation; and continuing efforts to enhance campus social life. This revised version was published online in June 2006 with corrections to the Cover Date.  相似文献

This paper follows on from the authors’ previous research into minimal Black teacher representation in Liverpool schools [Boyle, B., and M. Charles. 2010. “Tightening the Shackles: The Continued Invisibility of Liverpool's British African Caribbean Teachers.” Journal of Black Studies 42 (3): 427–435]. It is based on a re-examination of their findings of Liverpool's Black teachers’ historic institutionalised invisibility [Swann Report. 1985. Education for All. Report of the Committee of the Enquiry into the Education of Children from Ethnic Minority Groups. London: Her Majesty's Stationery Office.] and an interrogation of the situation as revealed by the 2015 data. The article uses as its evidence base, questionnaire responses and data from a sample of interviews with the current 18 Black teachers. Despite the voices of Black teachers being marginalised and even less likely to be heard, it is vital that the pedagogies of Black teachers contribute to a ‘dismantling of binaries and hierarchies that privilege Eurocentric paradigms of teaching’ [Escayg, K. 2010. “Diverse Classrooms, Diverse Teachers: Representing Cultural Diversity in the Teaching Profession and Implications for Pre-Service Admissions.” Canadian Journal for new Scholars in Education 3 (2): 1–8, 4].  相似文献
