Information retrieval in the workplace: A comparison of professional search practices     

Tony Russell-Rose  Jon Chamberlain  Leif Azzopardi 《Information processing & management》2018,54(6):1042-1057

Legal researchers, recruitment professionals, healthcare information professionals, and patent analysts all undertake work tasks where search forms a core part of their duties. In these instances, the search task is often complex and time-consuming and requires specialist expertise to identify relevant documents and insights within large domain-specific repositories and collections. Several studies have been made investigating the search practices of professionals such as these, but few have attempted to directly compare their professional practices and so it remains unclear to what extent insights and approaches from one domain can be applied to another. In this paper we describe the results of a survey of a purposive sample of 108 legal researchers, 64 recruitment professionals and 107 healthcare information professionals. Their responses are compared with results from a previous survey of 81 patent analysts. The survey investigated their search practices and preferences, the types of functionality they value, and their requirements for future information retrieval systems. The results reveal that these professions share many fundamental needs and face similar challenges. In particular a continuing preference to formulate queries as Boolean expressions, the need to manage, organise and re-use search strategies and results and an ambivalence toward the use of relevance ranking. The results stress the importance of recall and coverage for the healthcare and patent professionals, while precision and recency were more important to the legal and recruitment professionals. The results also highlight the need to ensure that search systems give confidence to the professional searcher and so trust, explainability and accountability remains a significant challenge when developing such systems. The findings suggest that translational research between the different areas could benefit professionals across domains.  相似文献   

Teaching the partial products algorithm with the concrete representational abstract sequence and the strategic instruction model     

Margaret M. Flores  Alexcia J. Moore  Jill M. Meyer 《Psychology in the schools》2020,57(6):946-958

Elementary standards include multiplication of single-digit numbers and students advance to solve complex problems and demonstrate procedural fluency in algorithms. The ability to illustrate procedural fluency in algorithms is dependent on the development of understanding and reasoning in multiplication. Development of multiplicative reasoning provides the foundation for advanced mathematics and algebraic reasoning. For students who struggle in mathematics, instruction in multiplication algorithms should ensure conceptual understanding so that students have a foundation for success in advanced mathematics. The concrete representational abstract (CRA) sequence addresses conceptual understanding and the strategic instruction model (SIM) supports procedural knowledge. The current pilot study combined these methods to teach elementary students the partial products algorithm. Twelve students in grades four and five participated in the study, receiving instruction from teachers in their school during an intervention period. Within a pre-experimental design, using pre- and postintervention data, students showed a significant change in performance. The article will describe and show how teachers implemented the CRA-SIM interventions and discuss implications for practice.  相似文献   

From peripheral to full participation in a blended trade bargaining simulation     

Tony Carr  lenda Cox  ndrea Eden  Monique Hanslo 《British journal of educational technology : journal of the Council for Educational Technology》2004,35(2):197-211

This article considers the extent and nature of student participation in a trade bargaining simulation from a community of practice perspective. This third‐year economics module included a blend of online communication (through email, online chats and online discussions) and face‐to‐face meetings, both in smaller bargaining groups and in whole class plenary meetings. Our method of analysis includes the use of Exchange Structure Analysis of text chats and face‐to‐face learning conversations, triangulated by observation, survey and interview data. The focus on community of practice enables us to offer a nuanced interpretation of differences in crude participation data derived from the online chats. Superficially, the data may suggest marginalisation of participants, but Wenger's (1988 ) notion of peripheral participation with a trajectory towards full participation reframes the disparities in terms of an active community of practice. Some members are fully engaged with the practices of trade bargaining from the early stages of the simulation, while others move towards full participation over the duration of the simulation. Our results suggest that the laboratory‐based online text chats did provide opportunities for student participation in the simulation, and that male and female students exhibited different patterns of participation in the chats.  相似文献

Impressions of disadvantage: II-Monitoring and assisting the student at risk     

J. H. F. Meyer  A. F. Cliff  T. T. Dunne 《Higher Education》1994,27(1):95-117

Two studies on monitoring and assisting students at risk are presented against a contemporary perspective in higher education: that of monitoring and developing the quality of student learning. A basis for risk categorisation at an individual level is outlined, and the effects of an intervention aimed at students at risk are evaluated in two contrasting settings. At risk in the present study represents, in conceptual terms, a relatively extreme set of learning behaviours.The first study approximates an ideal set of circumstances in which an individual-level intervention for students conceptually at risk is described. The second study reflects the uncompromising reality of a large first-year service course, in which a reduced form of the same intervention was pragmatically attempted. In both interventions the emphasis was on assisting students to engage manifestations of their own self-reported, contextualised study behaviour. This was the starting point of a developmental and reflective programme in which students were not taught study skills, but were rather assisted to develop deeper contextual perceptions, metalearning awareness, and internal locus.The targeted students in these studies, and the basic nature of the intervention employed, differ considerably from those used in other intervention studies. The first study produced positive results, while the second study did not. An overall conclusion is that, while interventions of the type described can assist students to develop their learning potential, they can only do so in carefully managed circumstances that are sensitive to individual students' learning problems and the discipline-specific context in which these occur.  相似文献

Gendered harassment in secondary schools: understanding teachers’ (non) interventions     

Elizabeth J. Meyer 《Gender and education》2008,20(6):555-570

This article provides an analysis of teachers’ perceptions of and responses to gendered harassment in Canadian secondary schools based on in‐depth interviews with six teachers in one urban school district. Gendered harassment includes any behaviour that polices and reinforces traditional heterosexual gender norms such as (hetero)sexual harassment, homophobic harassment, and harassment for gender non‐conformity. This study shows that educators experience a combination of external and internal influences that act as either barriers or motivators for intervention. Some of the external barriers include: lack of institutional support from administrators; lack of formal education on the issue; inconsistent response from colleagues; fear of parent backlash; and negative community response. By gaining a better understanding of the complex factors that shape how teachers view and respond to gendered harassment, we can work towards more effective solutions to reduce these behaviours in schools.  相似文献   

Testing Measurement Invariance Across Unobserved Groups: The Role of Covariates in Factor Mixture Modeling     

Yan Wang  Eunsook Kim  John M. Ferron  Robert F. Dedrick  Tony X. Tan  Stephen Stark 《Educational and psychological measurement》2021,81(1):61

Factor mixture modeling (FMM) has been increasingly used to investigate unobserved population heterogeneity. This study examined the issue of covariate effects with FMM in the context of measurement invariance testing. Specifically, the impact of excluding and misspecifying covariate effects on measurement invariance testing and class enumeration was investigated via Monte Carlo simulations. Data were generated based on FMM models with (1) a zero covariate effect, (2) a covariate effect on the latent class variable, and (3) covariate effects on both the latent class variable and the factor. For each population model, different analysis models that excluded or misspecified covariate effects were fitted. Results highlighted the importance of including proper covariates in measurement invariance testing and evidenced the utility of a model comparison approach in searching for the correct specification of covariate effects and the level of measurement invariance. This approach was demonstrated using an empirical data set. Implications for methodological and applied research are discussed.  相似文献

The flow of technological innovation in an R & D department     

Arnoud C. L. De Meyer 《Research Policy》1985,14(6):315-328

The flow of technological information, in particular the type of sources and transfer channels for technological information has been a focus of research interest since the very first studies concerning management of research and development. However, the results of these empirical studies, although encouraging and useful to managers, leave several questions unanswered, and even worse, contain some contradictions.In this paper we will try to explain some of these contradictions using the technology characteristics as an contingency factor. The model, which we will present has been tested in a twofold way: questionnaires were used to provide insight into the importance of some sources, while interviews on the basis of standardized problems led us to a better insight into sources and channels.  相似文献
