Developing a hypothetical multi‐dimensional learning progression for the nature of matter

We describe efforts toward the development of a hypothetical learning progression (HLP) for the growth of grade 7–14 students' models of the structure, behavior and properties of matter, as it relates to nanoscale science and engineering (NSE). This multi‐dimensional HLP, based on empirical research and standards documents, describes how students need to incorporate and connect ideas within and across their models of atomic structure, the electrical forces that govern interactions at the nano‐, molecular, and atomic scales, and information in the Periodic Table to explain a broad range of phenomena. We developed a progression from empirical data that characterizes how students currently develop their knowledge as part of the development and refinement of the HLP. We find that most students are currently at low levels in the progression, and do not perceive the connections across strands in the progression that are important for conceptual understanding. We suggest potential instructional strategies that may help students build organized and integrated knowledge structures to consolidate their understanding, ready them for new ideas in science, and help them construct understanding of emerging disciplines such as NSE, as well as traditional science disciplines. © 2009 Wiley Periodicals, Inc.

A model of equitable and sustainable redistribution of knowledge

Education is one of the pillars in which a Welfare State is effectively based on in order to achieve an equitable distribution of wealth. In contemporary society, knowledge and education are among the most appreciated goods, and everyone should have the right to acquire them, without distinction of gender, race, age, health or religion. From our experience of over 15 years at the Universitat Oberta de Catalunya we can claim that virtual learning makes access to education easier for certain population strata, whereas otherwise, they would be excluded from such a right. A very significant group of students to consider are women with family burdens who, thanks to this kind of education, are able to gain access to higher education for the first time in their lives and at their maturity ages. Another significant group is students with disabilities, for whom virtual education makes it possible to get training in fields for which it would be more difficult to get in the case of the non-virtual university. Geographic factors are also relevant, since virtual education has provided rural areas and other places with poor infrastructures with a chance to gain access to higher education. This brings with it a redistribution of wealth among territories, and also among different social strata with fewer resources and limitations to commute long distances to higher education institutions. Another issue that needs pointing out is virtual communication. As it is asynchronic, it can lead to a high degree of reflection. All these elements enable us to have a virtual discussion about cultural and linguistic issues which have huge educational value.     

Google Scholar,Web of Science,and Scopus: A systematic comparison of citations in 252 subject categories

Despite citation counts from Google Scholar (GS), Web of Science (WoS), and Scopus being widely consulted by researchers and sometimes used in research evaluations, there is no recent or systematic evidence about the differences between them. In response, this paper investigates 2,448,055 citations to 2299 English-language highly-cited documents from 252 GS subject categories published in 2006, comparing GS, the WoS Core Collection, and Scopus. GS consistently found the largest percentage of citations across all areas (93%–96%), far ahead of Scopus (35%–77%) and WoS (27%–73%). GS found nearly all the WoS (95%) and Scopus (92%) citations. Most citations found only by GS were from non-journal sources (48%–65%), including theses, books, conference papers, and unpublished materials. Many were non-English (19%–38%), and they tended to be much less cited than citing sources that were also in Scopus or WoS. Despite the many unique GS citing sources, Spearman correlations between citation counts in GS and WoS or Scopus are high (0.78-0.99). They are lower in the Humanities, and lower between GS and WoS than between GS and Scopus. The results suggest that in all areas GS citation data is essentially a superset of WoS and Scopus, with substantial extra coverage.     

Co-operatives and education in the Basque Country: the ikastolas in the final years of Franco’s dictatorship

This article analyses the creation of the schools called ikastolas throughout the Basque Country from the 1960s onwards. The name ikastola refers to a unique school model whose major characteristic is to teach the majority of subjects in the Basque language, or euskera. It outlines the reasons why some of these schools took a co-operative organisational form and describes their major characteristics. The first part analyses the opportunities created under the Francoist regime for this kind of school, despite the repressive character of the dictatorship in other fields. The second part of the paper examines the important influence of the Mondragón co-operative movement, especially through its financial institution, in the creation of these educational co-operatives. The third and last part emphasises the role played by social mobilisation in defence of the Basque language in the creation of these schools and how this factor tied in with a co-operative governance system.     

Empathy and critical thinking: primary students solving local environmental problems through outdoor learning

The present study explores the outcomes of teaching empathy and critical thinking to solve environmental problems. This investigation was done throughout the duration of an environmental education course within a primary school located in central Chile. A community-based research methodology was used to understand the formation of empathy and critical thinking. The findings reveal a significant benefit in using empathy strategies to engage students regarding the thinking processes involved with solving environmental problems. Using these elements as teaching techniques for environmental education courses can be very helpful in reaching the aims of creating a sustainable citizenry.     

Individual differences and the development of joint attention in infancy

This study examined the development of joint attention in 95 infants assessed between 9 and 18 months of age. Infants displayed significant test-retest reliability on measures of following gaze and gestures (responding to joint attention, RJA) and in their use of eye contact to establish social attention coordination (initiating joint attention, IJA). Infants displayed a linear, increasing pattern of age-related growth on most joint attention measures. However, IJA was characterized by a significant cubic developmental pattern. Infants with different rates of cognitive development exhibited different frequencies of joint attention acts at each age, but did not exhibit different age-related patterns of development. Finally, 12-month RJA and 18-month IJA predicted 24-month language after controlling for general aspects of cognitive development.     

Nothing in the History of Spanish <Emphasis Type="Italic">Anís</Emphasis> Makes Sense,Except in the Light of Evolution

We describe, discuss and illustrate a metaphoric parallel between the history of the most famous Spanish liqueur, “Anís del Mono” (Anís of the Monkey), and the evolution of living organisms in the light of Darwinian theory and other biological hypotheses published subsequent to Charles Darwin’s Origin of Species. Also, we report the use of a caricature of a simian Darwin with a positive connotation, perhaps the only one ever produced. We conclude that, like some species in the natural world, Anís of the Monkey has evolved, adapted, survived and become the fittest and most successful anís in the Spanish market and possibly the world. We hope this paper will contribute a new useful metaphor for the teaching of biological evolution.     

Identification of Early Risk Factors for Developmental Delay

Statewide birth certificate and preschool exceptionality records were integrated to identify risk factors for developmental delay (DD). Epidemiological methods were used to investigate both individual-level and population-level risk for DD associated with a number of child and maternal factors. Infants born with very low birth weight were at the greatest individual-level risk for DD, whereas prematurity (gestational age less than 37 weeks) and low maternal education posed the greatest population-level risk. For comparative purposes, individual-level risk for speech disability and other developmental disabilities was also determined. The individual-level risk associated with nearly all factors was significantly greater for DD than for speech disability or other developmental disabilities. The present study suggests that information available from birth certificate records can be used to target screening and early intervention services for children at high risk with the goal of reducing the incidence of DD and subsequent associated disabilities.
