This conceptual paper is concerned with the discursive and applied attributes of ‘authenticity’ in higher education, with a particular focus on teaching science through student research. Authenticity has been mentioned in passing, claimed or discussed by scholars in relation to different aspects of higher education, including teaching, learning, assessment and achievement. However, it is our position that in spite of the growing appeal of authenticity, the use of the term is often vague and uncritical. The notion of authenticity is complex, has a range of meanings and is sometimes contested. Therefore, we propose here a practice-oriented and theoretically-informed framework for what constitutes authenticity within the context of teaching through research. This framework brings together aspects of the ‘real world,’ existential self, and embedded meaning, and aligns them with different outcomes relating to knowledge and to students. Different models of teaching through research with conflicting claims to authenticity are used to illustrate the framework. 相似文献

The governments of cities have to make important decisions on the future of their communities. In the past, the vision, objectives, and goals of cities have been determined mainly by considering tangible assets as the main factors of a city's prosperity. However, in the knowledge economy, the role of intangible assets in wealth creation has become fundamental. As a result, a framework of intangible assets that allows navigation from the present reality to the future vision has become an urgent need for all cities. The paper has two well-defined parts. In the first part, it develops a specific methodology and framework for measuring and managing the intellectual capital of cities. In the second part, the study deals with the practical application of this model of intellectual capital in cities with the specific case of the city of Mataró, providing some details of the first cities’ intellectual capital report. 相似文献

The purposes of this study were, on one had, to determine the impact of a peer tutoring program on preventing academic failure
and dropouts among first-year students (N = 100), from Civil Engineering, Economics, Pharmacy, and Chemical Engineering careers; while, on the other hand, to identify
the potential benefits of such tutoring program on the cognitive and metacognitive learning strategies and social skills of
student mentors in their last year of studies or already in a postgraduate program (N = 41) at the University of Granada (Spain). After building and selecting the measurement instruments necessary to gather
demographic and academic relevant information on both samples, and assigning first-year students to either an experimental
or control group, the intervention consisted of ten 90-min tutoring sessions during the first semester lead by student tutors
who, in turn, had undergone four 3-h training sessions on tutoring contents like planning and time management, cognitive and
metacognitive learning strategies, motivational strategies and the use of materials designed ad hoc for this program. The results show differences in favour of the treatment group on grade point average, performance rate,
success rate and learning strategies and, also, statistically significant pre-post differences for the tutors on learning
strategies and social skills. 相似文献

The purpose of the present study was to assess the effectiveness of a phonological awareness training program in the specific
context of the Luxembourgish educational system. The intervention was run by the kindergarten teachers in their classes with
minimal external supervision. Forty-one classes of the area around Luxembourg City participated in the study. One hundred
and fifty children from 20 kindergarten classes were part of the training group and 157 children from 21 classes formed the
control group. At the end of kindergarten, clear training effects were observed for all phonological awareness tasks, except
for the highly demanding phoneme deletion task. After 6 months of reading and writing instruction in first grade, no training
effects were found in a pseudoword spelling task for the entire training group. Only at-risk children, which had the lowest
performance on preschool phonological awareness measures, showed significant training effects. We conclude that early phonological
awareness training may be profitably incorporated in kindergarten classroom activities, particularly for at-risk pupils, even
when the language characteristics and teaching methods already concur in facilitating the understanding of the alphabetic
principle. 相似文献

This paper provides evidence of the effects of adult literacy on individuals’ income and employability in Brazil based on information obtained from the monthly employment survey (PME). The OLS results indicate that after controlling for observable characteristics, there is a 21.25% increase in wages for individuals who become literate; however, there is no significant impact on employability. Moreover, the findings show an 8.1% increase in the probability of being employed in the formal sector. We also explore the longitudinal structure of the dataset to control for unobservable fixed characteristics of individuals. The fixed-effects estimators show smaller effects compared to the OLS estimators. We find that literacy has a 4.4% effect on wages and a 4.3% impact on the probability of being formally employed. The effects are significantly different from zero. 相似文献

In distributed and cooperative systems, the network structure is determinant to the success of the strategy adopted to solve complex tasks. Those systems are primarily governed by consensus protocols whose convergence is intrinsically dependent on the network topology. Most of the consensus algorithms deal with continuous values and perform average-based strategies to reach cohesion over the exchanged information. However, many problems demand distributed consensus over countable values, that cannot be handled by traditional protocols. In such a context, this work presents an approach based on semidefinite programming to design the optimal weights of a network adjacency matrix, in order to control the convergence of a distributed random consensus protocol for variables at the discrete-space domain, based on the voter model. As a second contribution, this work uses Markov theory and the biological inspiration of epidemics to find out a dynamical spreading model that can predict the information diffusion over this discrete consensus protocol. Also, convergence properties and equilibrium points of the proposed model are presented regarding the network topology. Finally, extensive numerical simulations evaluate the effectiveness of the proposed consensus algorithm, its spreading model, and the approach for optimal weight design. 相似文献

This paper contributes to the ongoing debate on the impact of academic patenting on publishing and knowledge transfer. Drawing upon two separate surveys of academics, and their CV information, we provide empirical evidence for UK academics in engineering and physical sciences. The contribution of this paper is two-fold. First, our findings show that (the intensity of) academic patenting complements publishing up to a certain level of patenting output, after which we find evidence of a substitution effect. We also find weak evidence of important differences across scientific fields with the more basic-oriented fields showing indications of a crowding-out effect. Second, our analysis of the potential impact of patenting on knowledge transfer shows a positive correlation between the stock of patents and engagement in knowledge transfer channels. However, we find that a substitution effect sets in, indicating an inverted U-shaped relationship between patenting and several knowledge transfer channels. 相似文献
