Automatic evaluation of digital libraries with 5SQual

Digital libraries (DLs) are complex information systems which can present changes in their structure, content, and services. These complexities and dynamics make system maintenance a non-trivial task, since it requires periodical evaluation of the different DL components. Generally, these evaluations are customized per system and are performed only when problems occur and administrator intervention is required. This work aims to change the situation. We present 5SQual, a tool which provides ways to perform automatic and configurable evaluations of some of the most important DL components, among them, digital objects, metadata, and services. The tool implements diverse numeric indicators that are associated with eight quality dimensions described in the 5S quality model. Its generic architecture was developed to be applicable to various DLs and scenarios. In sum, the main contributions of this work include: (i) the design and implementation of 5SQual, a tool that validates a theoretical DL quality model; (ii) the demonstration of the applicability of the tool in several usage scenarios; and (iii) the evaluation (with usability specialists) of its graphical interface specially designed to guide the configuration of 5SQual evaluations. We also present the results of interviews conducted with administrators of real DLs regarding their expectations and opinions about 5SQual.     

Reasoning by analogy: Is it schema-mediated or case-based?

One of the “classical” ways of learning consists of studying examples of already solved problems. In two experiments, we analyzed the degree of abstraction of the knowledge used by ninth grade students to solve algebra problems after studying worked examples. The results showed that there are two processes underlying reasoning by analogy, one that uses abstract knowledge and another that involves case-based reasoning. Both experiments pointed out interindividual differences in the population under study: when given examples, some subjects seem to extract the structure of the solving process by comparing the worked examples, while others focus more on the specifics of each example. To these two processes correspond two levels of transfer: correctly solve problems that have the same structure as the examples, regardless of how similar they are, or be better at solving problems that resemble the examples the most. Experiment 2 used a dual-task paradigm to show that some subjects implement both processes, in which case the mental load is greater. This experiment also showed that both processes can lead to the long-term acquisition of the principles behind the examples.     

Are we promoting critical autonomous thinking? A discussion on conversational genres and whether they can help us answer this question

This work is based on the assumption that if the classroom is a space in which manifestations of critical autonomous thinking appear systematically, then it promotes that same kind of thinking by the students, in other contexts. But what count as manifestations of critical autonomous thinking, and how can we observe them? As Robert Young's Habermasian work on indoctrination and conversational genres seemed a promising conceptual framework for understanding classroom situations in this respect, we took it as a starting point for exploring answers to these questions. Our exploration, both through fieldwork and theoretical reflection, led us to some findings, among which are (1) the existence of new genres which refine the conceptual categories originally formulated by Young; (2) that analysis of function is not enough, requiring also a contents dimension with which one can study what critical autonomous thinking is promoted about, in particular classroom situations; and (3) that classroom situations can be more contradictory and fragmented than presupposed by the very idea of genre.     

Questioning a tradition: A French way of excellence

The following article was written in French as a keynote speech at the IGIP Symposiumat the Biel School of Engineering (University of Applied Sciences, in Biel, Switzerland), held in March 2000. The topic of this symposium was 'Unique and Excellent'. It aimed to show that engineering education cannot really head towards unification, but will reach uniqueness and excellency if there are many different ways of educating engineers. What happens on the spot, in each technical university, in each course, is much more important for excellence than the fact that all curricula can be compared directly at an international level. Owing to the very particular way of educating engineers in France, it was considered most important to learn about this particular organization. André Béraud accepted presenting it to the audience. His contribution had a very lively echo. The text presents a short outline of the history of French engineering education and its very particular ways and means. Engineering is not taught at technical universities but at Grandes Ecoles (Grand Schools), which represent a very high level of education open only to the very best. They will form the élite of the public servants of France, much more than what is generally considered the task of an engineer. In consequence, the education is broadly based with humanities as an important element in it; it is also very scientific, with mathematics and theoretical physics as central topics. The disadvantage of such a system lies in the fact that it is most rigid, not very open to the needs of industry and of foreign students. There have been, however, some changes.     

What If the Doors of Every Schoolhouse Opened to Social-Emotional Learning Tomorrow: Reflections on How to Feasibly Scale Up High-Quality SEL

Social-emotional learning (SEL) refers to a set of competencies that form the basis of human interaction. So, SEL in schools is no fad. But what would happen if every school actively wanted to bring in SEL tomorrow? Using the articles in the special issue on SEL as a springboard, this article looks at the neurological basis of SEL, SEL best practices, approaches to SEL instruction, assessment, and the complex issue of SEL and equity, and it reflects on the implications of these areas for scaling up sooner rather than later. Specific guidelines are provided, starting with this basic point: There are not enough experts available to guide this process, so schools must invest in staff learning about SEL, its rootedness in our biology, its basic role in accomplishing everything humans try to accomplish, and what we know about best practices and must provide cohort-based, ongoing professional development experiences that provide continuous support.     

The impact of the Programme for International Student Assessment on academic journals

The aim of this study is to assess the impact of PISA (Programme for International Student Assessment) on international scientific journals. A bibliometric analysis was conducted of publications included in three main scientific publication databases: Eric, EBSCOhost and the ISI Web of Knowledge, from 2002 to 2010. The paper focused on four main questions: who carried out these studies, in which academic journals have the articles been published, what has been the evolution of these publications and what were the main article topics? The study concludes that PISA has had a considerable impact on the scientific research, reflected primarily by university-based authors from the areas of education and social sciences analysing student performance. The evolution since 2007 seems to indicate that more articles will be published in coming years through the initiative of researchers (rather than the editorial boards), even from other scientific areas, thus increasing the number of topics of analysis.

How gay and bisexual men compensate for the lack of meaningful sex education in a socially conservative state

The information shared in schools on sex education in the USA is highly variable depending on the state and sometimes city in which a student lives. Gay and bisexual students living in a socially conservative, primarily rural state such as Oklahoma often receive little information about sexual health information that pertains to their behaviours unless it is discussing the dangers of sex. Using a qualitative approach, 20 gay and bisexual men currently residing in Oklahoma completed semi-structured interviews about their experiences with sex education and alternate ways to compensate for lack of information provided. Participants noted an awareness of the lack of meaningful sex education or if it was offered, a primary focus on abstinence-only until marriage heteronormative curricula. Participants described various ways they compensated for lack of sex education including accessing pornography and information from the internet. With the current socio-political environment of Oklahoma, it is unlikely wholesale changes to the sex education curricula can be made. The importance of public health professionals using the internet and peer educators to deliver inclusive and informative sexual health information remains salient and viable for men who reside in socio-politically conservative areas like Oklahoma.     

What's in a rating?

We examine the relationship between the formal ratings that principals give teachers and a variety of observable teacher characteristics, including proxies for productivity. Prior work has shown that principals can differentiate between more and less effective teachers, especially at the tails of the quality distribution, and that subjective evaluations of teachers are strongly correlated with subsequent student achievement. However, whereas prior work has relied on survey data, we consider formal ratings from a setting in which the stakes are reasonably high. We find that the ratings are correlated with an array of teacher qualities including experience for young teachers, education credentials, and teacher absenteeism. Our finding that principals reward qualities of teachers known to be related to student productivity provides reason to be optimistic about policies that would assign more weight to principal evaluations of teachers in career decisions and compensation.
