COLLEGE RANKINGS: Democratized College Knowledge for Whom?

Every fall the opening of the academic year is heralded by an ever increasing number of newsmagazines that rank colleges. In addition to the standard bearers of this market — U.S. News and World Report and Money — magazines that offer their readers advice on how to choose a college are proliferating. For example, one can find lists of the "best colleges" and "best buys" accompanied on newstands by the top jock schools (Sports Illustrated), the best party schools (Playboy), and the best colleges for Asian Americans (A. Magazine). This paper is a study of who uses the contentious and seemingly influential newsmagazine rankings of U.S. colleges and universities, and an analysis of what types of freshmen find these rankings useful in making their choice of college. Equally important, it is a discussion of why reputations are important and how they can serve as a hedge against uncertainty. Finally, the paper provides an analysis of the for-profit sector's encroachment into a critical educational equity arena-college access-embedded within a discussion of whether widely available college rankings result in democratized college knowledge.     

Engineering courses and accreditation in Portugal

The Accreditation System for Engineering Courses was launched by the Ordem dos Engenheiros (OE—Institute of Portuguese Engineers) in 1994. Although the process was not easily accepted at first, it eventually took hold as engineering schools became aware of the public's interest in the system. Today, accreditation is an 'open door' to the OE since it exempts applicants from writing the admission exam. In fact, it is a 'seal of quality'—a guarantee of the initial education quality on the engineer's path to professional practise. This paper describes our system and what we have learned from implementing it, from the experience of others and from our own mistakes; but note that what is written is not a Utopia— the system does work.     

Reception learning and self-discovery learning in histology: Students' perceptions and their implications for assessing the effectiveness of different learning modalities

Two questionnaires were used to investigate students' perceptions of their motivation to opt for reception learning (RL) or self‐discovery learning (SDL) in histology and their choices of complementary learning strategies (CLS). The results demonstrated that the motivation to attend RL sessions was higher than the motivation to attend SDL to gain new knowledge (P < 0.01) and to apply this acquired knowledge to diagnosis (P < 0.01), therapy (P < 0.01), and research (P < 0.05). Students also showed a stronger preference for RL based on motivations related to leadership (P < 0.01) and competition (P < 0.01), although the rates were very low in both cases (≤ 1.9 ± 1.1). Statistically significant differences were found between male and female students for leadership (higher in males), responsibility (higher in females), and acquiring new knowledge (higher in females only in RL). This study's findings for students' preferred CLS strategies suggested a greater need for additional complementary resources after RL than after SDL (P < 0.01). In conclusion, RL was associated with a greater need for complementary training resources such as textbooks, atlases, the internet, audiovisual media, and tutorials, whereas SDL was associated with a greater need to orient teaching and training toward medical practice. These results suggest the need to reorient both types of learning processes to enhance their effectiveness in teaching histology, especially in the case of SDL, which should place more emphasis on clinically oriented knowledge.

Defending Constructivism in Science Education

After an impressive development throughout the last two decades, supported by a greatamount of research and innovation, science education seemed to be becoming a newscientific domain. This transformation of Science Education into a specific field of researchand knowledge is usually associated with the establishment of what has been called anemergent consensus about constructivist positions. However, some voices have begunto question these constructivist positions and therefore the idea of an advancementtowards a coherent body of knowledge in the field of science education. The goalof this work is to analyse some of the current criticisms of the so-called constructivistorientations and to study their implications for the development of science education asa coherent body of knowledge.     

Numerical study of dc-biased ac-electrokinetic flow over symmetrical electrodes

This paper presents a numerical study of DC-biased AC-electrokinetic (DC-biased ACEK) flow over a pair of symmetrical electrodes. The flow mechanism is based on a transverse conductivity gradient created through incipient Faradaic reactions occurring at the electrodes when a DC-bias is applied. The DC biased AC electric field acting on this gradient generates a fluid flow in the form of vortexes. To understand more in depth the DC-biased ACEK flow mechanism, a phenomenological model is developed to study the effects of voltage, conductivity ratio, channel width, depth, and aspect ratio on the induced flow characteristics. It was found that flow velocity on the order of mm/s can be produced at higher voltage and conductivity ratio. Such rapid flow velocity is one of the highest reported in microsystems technology using electrokinetics.     

Promoting Gypsy children's behavioural engagement and school success: Evidence from a four‐wave longitudinal study

Low schooling, high non‐attendance and school dropout rates are critical phenomena within disadvantaged groups, especially among the Gypsy community. For example, in the UK, 10%–25% of Gypsy children do not attend school regularly and have significantly higher levels of overall absence from school (percentage of half‐day sessions missed) than pupils from other ethnic groups. In Portugal, available data on Gypsy children is sparse, yet data from one geographic region of the country reports high school failure (45%) and dropout rates (15%) among this population. The present study assessed the efficacy of a four‐year intervention to promote Gypsy children's behavioural engagement and school success. Gypsy communities were contacted and 30 children participating in the four waves were randomly distributed into control and experimental groups. Every school day throughout four years, 16 children in the experimental group were called at home and invited to go to school. The effectiveness of the intervention was evaluated in four waves (at the end of each of the four school years), assessing behavioural engagement (i.e. school non‐attendance, classroom behaviour) and school achievement (i.e. mathematics achievement, student progression). Findings show the efficacy of the intervention on promoting behaviour engagement and academic success without devaluing Gypsy people's culture.     

The effect of external and internal factors on firms’ product innovation

In this article we analyse the effect of factors external and internal to the firm, on product innovation novelty, and how this effect varies by industry. We estimate three econometric models to determine the individual effects of these factors, their joint explanatory power and the effects of interactions among them. The analysis is based on a sample of 6094 manufacturing firms, taken from the Spanish Survey of Technological Innovation 2000. The results indicate that the firm's technological competences, derived from in-house R&D, are the main determinant of product innovation. They also suggest that in the presence of high levels of such competences, the technological opportunities deriving from non-industry agents become less important as determinants of innovation. We show that the determinants of innovation vary depending on the industrial sector and the degree of novelty of the product developed.     

“Spanish as a foreign language” teachers’ profiles: inclusive beliefs, teachers’ perceptions of student outcomes in the TCLA program, burnout, and experience

The present study focuses on the Temporary Classroom of Linguistic Adaptation program (TCLA program) in which specialist teachers (Spanish as a foreign language teachers—SFL teachers) teach Spanish to immigrants who are not proficient in the language. We suggest that support for immigrant students in Spanish schools should adopt a new inclusive educational approach. The present investigation is a preliminary attempt at characterizing the profiles of SFL teachers by assessing, simultaneously, five relevant variables (through cluster analysis): inclusive beliefs, teachers’ perceptions of student outcomes in TCLA program, general burnout, diversity-related teacher burnout, and years of teaching experience. Eighty-one SFL teachers from 132 schools in Spain (EU) were asked to complete a self-report questionnaire. Cluster analysis found two clearly differentiated groups: the larger one, Innovative SFL Teachers and the smaller, Traditional SFL Teachers. The Traditional SFL Teachers are characterized by more years of experience, lower inclusive beliefs scores, lower teachers’ perception of student outcomes in the TCLA program scores, and higher burnout scores as compared with the Innovative SFL Teachers. Moreover, Traditional SFL Teachers conceptualize their teaching role as a "teacher of Spanish" whereas Innovative SFL Teachers see themselves much more as playing a supportive role.
