AbstractPersonalized learning refers to a collection of practices designed to place student interests and needs at the heart of schooling. Schools that implement personalized learning need leaders that support educators and students in redesigning the core practices of teaching and learning in K-12 schools. To answer the question of how leaders support this redesign, we use distributed leadership theory to focus on the macrotasks and microtasks that leaders enact to create the conditions for personalized learning practices. Drawing on a five-year, qualitative study of 11 personalized learning programs in the Midwest, we identify three macrotasks supporting personalized learning: reorganizing learning environments to support student voice and choice, assembling idiosyncratic technology ecosystems to distribute teaching and learning tasks, and redesigning instructional time to prioritize student’s interests, agency, and learning relationships. After we describe a number of microtasks associated with each macrotask, we discuss how a consideration of these kinds of leadership tasks can open the contemporary discussion of personalized learning from a narrow focus on learning technologies to an expansive vision of student-centered school reform. 相似文献

Most of the fastest-growing string collections today are repetitive, that is, most of the constituent documents are similar to many others. As these collections keep growing, a key approach to handling them is to exploit their repetitiveness, which can reduce their space usage by orders of magnitude. We study the problem of indexing repetitive string collections in order to perform efficient document retrieval operations on them. Document retrieval problems are routinely solved by search engines on large natural language collections, but the techniques are less developed on generic string collections. The case of repetitive string collections is even less understood, and there are very few existing solutions. We develop two novel ideas, interleaved LCPs and precomputed document lists, that yield highly compressed indexes solving the problem of document listing (find all the documents where a string appears), top-k document retrieval (find the k documents where a string appears most often), and document counting (count the number of documents where a string appears). We also show that a classical data structure supporting the latter query becomes highly compressible on repetitive data. Finally, we show how the tools we developed can be combined to solve ranked conjunctive and disjunctive multi-term queries under the simple \({\textsf{tf}}{\textsf{-}}{\textsf{idf}}\) model of relevance. We thoroughly evaluate the resulting techniques in various real-life repetitiveness scenarios, and recommend the best choices for each case. 相似文献

This paper examines the relative influence of factors affecting the college choice decisions of graduate students. It is based on a 1986 survey of 2,834 admitted students at a major research university, to which 38 percent of the sample responded. Factor analysis of ratings of importance of 31 college characteristics yielded dimensions upon which student decisions are based. These results were used to build five scales of importance and preference, which were then tested with other variables in a regression model in which the dependent variable was the decision to enroll or not to enroll at the surveying institution. The following were found to influence decisions: residency status, quality and other academic environment characteristics, work-related concerns, spouse considerations, financial aid, and the campus social environment.A paper presented at the Annual Forum of the Association for Institutional Research, New Orleans, May 29–June 1, 1994. 相似文献

Conclusions In university settings good leadership seems to depend, among other factors, on the culture of the department and the nature
of academic work in the field involved. Consequently, it is important to find solutions valid for the department involved.
The development work of academic leadership should be carried out in voluntary co-operation with the academic staff, starting
with the analysis of the current leadership culture. The departments may also have to change their cultures somehow in the
future because of the rapidly changing environment. The longer and the more successfully the ideas, assumptions, and values
dealing with the leadership have been working, the more difficult these changes might prove to be (Schein 1985).

Citizen users play important roles in the acceleration phase of energy transitions, during which small-scale renewable energy technologies (S-RET) become taken up more widely. From users’ perspective, turning the early, and typically slow, proliferation into a more rapid and widespread diffusion requires not only the adoption of S-RET but also the adaptation, adjustment, intermediation and advocacy of S-RETs. These activities become necessary because S-RET face a variety of market, institutional, cultural and environmental conditions in different countries. New Internet-based energy communities have emerged and acted as key user-side transition intermediaries that catalyse these activities by qualifying market information, articulating demand and helping citizen users to reconfigure the standard technology to meet the specificities of different local contexts. In doing so, Internet communities foster an appreciatively critical discourse on technology. Such user intermediation is important in expanding the markets for S-RET beyond that of enthusiasts, environmentalists and other early adopters, to the early majority of adopters who demand more exposure, clearer information and less uncertainty about new technology options. 相似文献

This paper presents a research-based teaching-learning sequence (TLS) that focuses on the notion of interaction in teaching Newton’s third law (N3 law) which is, as earlier studies have shown, a challenging topic for students to learn. The TLS made systematic use of a visual representation tool—an interaction diagram (ID)—highlighting interactions between objects and addressing the learning demand related to N3 law. This approach had been successful in enhancing students’ understanding of N3 law in pilot studies conducted by teacher-researchers. However, it was unclear whether teachers, who have neither been involved with the research nor received intensive tutoring, could replicate the positive results in ordinary school settings. To address this question, we present an empirical study conducted in 10 Finnish upper secondary schools with students (n?=?261, aged 16) taking their mandatory physics course. The study design involved three groups: the heavy ID group (the TLS with seven to eight exercises on IDs), the light ID group (two to three exercises on IDs) and the no ID group (no exercises on IDs). The heavy and light ID groups answered eight ID questions, and all the students answered four questions on N3 law after teaching the force concept. The findings clearly suggest that systematic use of the IDs in teaching the force concept significantly fostered students’ understanding of N3 law even with teachers who have no intensive tutoring or research background. 相似文献

In accordance with the education policy which puts human capital at its heart, higher education is expected to produce marketable competent professionals in response to the needs of an expansive knowledge-based economy. In one reading, to support competitive knowledge-based economy, higher education students should graduate as young and fast as possible. The article asks whether it is credible that the young & fast principle as an objective for university education would provide a feasible way of enhancing professional labour force to serve knowledge economies. The analysis of study careers of 17,000 European second cycle university graduates shows that transitions from school to higher education to professional employment vary considerably in the 12 countries. The key finding is that countries with rather slow progression in the initial part of the transition tend to do better in the end, and vice versa. Belgium (Flanders) is the most obvious example of young and fast-graduating students that need a relatively long period after graduation to start their professional careers. In Finland, Austria, and Norway, relatively old and experienced graduates are employed rapidly. The time before professional employment after graduation is short for students who have acquired relevant work experience and acquainted themselves with professional fields. The youngest professionals are found in France where they tend to have access to opportunities for professionally relevant training. However, professional employment cannot be fostered by simply trying to recruit student populations as young as possible, but rather by enriching the labour market relevance of their student careers. 相似文献
