Personalized Information Seeking Assistant (PiSA): from programming information seeking to learning     

Yihan?LuEmail authorView author&#;s OrcID profile  I-Han?Hsiao 《Information Retrieval》2017,20(5):433-455

Online programming discussion forums have grown increasingly and formed sizable repositories of problem-solving solutions. In this paper, we investigate programming learners’ information seeking behaviors in online discussion forums, and provide visual navigational support to facilitate information seeking. We design engines to collect students’ information seeking behaviors, and model these behaviors with sequence pattern mining techniques. The results show that programming learners indeed seek for information from discussion forums by actively search and read progressively according to course schedule topics. Advanced students consistently perform query refinements, examine search results and commit to read, however, novices do not. Finally, according to the lessons learned, we propose, design and evaluate Personalized Information Seeking Assistant system to help query refinement by summarizing the search results and to provide social-based browsing history. Findings suggest that paying attention to the query history may lead to further reading events, which subsequently resulting in potential learning activities.  相似文献

Affecting the flow of a proof by creating presence—a case study in Number Theory     

Mika?GabelEmail authorView author&#;s OrcID profile  Tommy?Dreyfus 《Educational Studies in Mathematics》2017,96(2):187-205

The notion of flow of a proof encapsulates mathematical, didactical, and contextual aspects of proof presentation. A proof may have different flows, depending on the lecturer’s choices regarding its presentation. Adopting Perelman’s New Rhetoric (PNR) as a theoretical framework, we designed methods to assess aspects of the flow of a proof. We present a case study from a Number Theory class at the beginning undergraduate level, focusing on an intervention concerning one lesson given in two consecutive years. The intervention consisted of a discussion with the lecturer about findings from Year-1 and potential changes in the flow of the proof before the Year-2 lesson. We analyze two aspects of the flow of the proof: the scope and organization of the argumentation and the presence (in the PNR sense) of different elements. Our analysis revealed that the intervention caused global and local changes in the flow and that PNR enables us to capture these changes.  相似文献   

The status games they play: unpacking the dynamics of organisational status competition in higher education     

Jelena?BrankovicEmail authorView author&#;s OrcID profile 《Higher Education》2018,75(4):695-709

The article uses the concept of organisational status to explore how universities respond to intensifying competition. Although status is not a novel phenomenon in higher education, recent insights show that the concerns with vertical positioning, both nationally and internationally, are gaining prominence with a growing number of universities worldwide. As global competition becomes as fierce as ever, universities’ efforts to maintain or advance their position vis-à-vis each other are becoming more salient. The paper draws from extant literature to identify three mechanisms of organisational status construction—categories, intermediaries and affiliations—and offers a set of propositions as to how universities of different status rank are expected to act when seeking to maintain or advance their status. Such activities, it is argued, shape status hierarchies, which, in turn, affect the scope of organisational action. The article contributes to the discussions on competition in higher-education literature and, more broadly, to the theory of organisational action in the tradition of sociological institutionalism.  相似文献   

One for Nine Ten: Cataloging for Consortia Collections,a UC model

ABSTRACT

In January 2000, the University of California created the Shared Cataloging Program (SCP). Based at the University of California, San Diego, the SCP is a “centralized cataloging model” for the California Digital Library consortium collections. This article will take an evolutionary look at the perpetual challenges of sustaining a consortial cataloging model and highlight the efforts of the SCP in the ongoing quest to eliminate the redundancy of efforts by centralizing the optimization of cataloging efficiency.  相似文献   

Students’ Learning Performance and Transitions in Different Learning Pathways to Higher Vocational Education     

Harm?BiemansEmail authorView author&#;s OrcID profile  Hans?Mari?n  Erik?Fleur  Hilde?Tobi  Loek?Nieuwenhuis  Piety?Runhaar 《Vocations and Learning》2016,9(3):315-332

To improve students’ transitions between successive educational levels, continuing learning pathways are being designed and implemented in many countries. This study was carried out to examine the effects of the Green Lycea (GL) as critical cases of continuing learning pathways in vocational education in The Netherlands. The GL were compared with a traditional pathway (pre-vocational secondary education and secondary vocational education offered as separate programmes) in terms of students’ learning performance and transitions. GL students and comparable students following the regular pathway yielded the same mean final exam scores for four core subjects in the first phase of their educational programmes, despite the fact that GL students took this exam one year earlier than regular students because of the acceleration of the learning trajectory in the GL programme. Regarding the students’ transitions, the GL and the traditional pathway yielded comparable percentages of students who either did or did not obtain a pre-vocational secondary education diploma; For the GL, however, the percentage of students who proceeded in secondary vocational education was higher. To conclude, it seems to be possible to improve students’ transitions between successive educational levels (with their learning performance being an important precondition) through continuing learning pathways such as the GL. In this regard, GL design characteristics as described and examined in this study can be valuable ingredients for continuing learning pathways internationally as well.  相似文献
