Zientzien irakaskuntza: Argumentazio gaitasuna eta datuen erabilera sustatzeko esku-hartze proposamen berritzailea

Gaur egun, konpetentzia zientifikoen garapena Lehen Hezkuntzako eskolan gutxi garatuta eta eztabaidagarria den gaia da. Ikasleek kultura zientifikoan murgiltzeko forma aurkitu eta, bereziki, argumentazio gaitasuna garatzen laguntzea, zientziak hitz egiteko aukerak emanez, ez da batere arrunta gure eskoletan. Esku-hartze berritzaile hau egoera honi aurre egiteko eta arazoari irtenbide bat bilatzeko diseinatuta izan da. Honen bidez, Lehen Hezkuntzan zientzienganako interesa sustatzen saiatzen da, zientziako klaseetan datuen erabilerari eta argumentazioari lehentasuna emanez. Ekimena 2013-2014ko martxoan jarri da martxan.

Zientzien irakaskuntza

[eus] Gaur egun, konpetentzia zientifikoaren garapena Lehen Hezkuntzako eskolan gutxi garatu den gaia da. Ikasleak kultura zientifikoan murgiltzeko forma aurkitu eta ikerketa gaitasuna garatzen laguntzea, planteatutako arazoei erantzuna bilatzeko ikerketa propioak diseinatuz, ez da batere arrunta gure eskoletan. Esku hartze hau, egoera honi aurre egiteko eta arazoari irtenbide bat bilatzeko diseinatuta izan da. Honen bidez, Lehen Hezkuntzan, ikasleak ikerketen bitartez zientzietan konpetenteagoak izatea da helburu nagusia. Martxan jarritako ekimenean, ikasle gehienak ikerketaren diseinua eraiki dute, emaitza hobeak lortu dira taldean aritu direnean eta flotagarritasuna dentsitatearekin lotzeko gai izan dira.

Zientzien irakaskuntza: argumentazio gaitasuna sustatzeko proposamena, sendagaien ezagupenaren bidez

[eus] Gaur egun, aditu desberdinek diotenez, Lehen Hezkuntzan konpetentzia zientifikoa garatzeko zailtasunak daude . Egoera hobetzeko, kultura zientifikoan murgiltzeko aukera, eta argumentazio gaitasuna garatzeko aukera eskaini behar zaie ikasleei. Esku-hartze honetan, eztabaida soziozientifikoen bidez, argumentazio gaitasuna lantzen da, sendagaien eraginkortasuna eta efektu sekundarioen arteko harremana eztabaidagai izanik. Esku-hartzea burutzean, ikusi ahal izan da adin txikiko ikasleak, aukera eskaintzen zaienean, argumentu justifikatuak emateko gai izan direla konpetentzia zientifikoa lortzeko bidea eraikiz. Aldi berean, sendagaien eraginkortasunaren eta efektu sekundarioen arteko harremanaz ohartu dira.

A neural extracellular matrix-based method for in vitro hippocampal neuron culture and dopaminergic differentiation of neural stem cells

Background: The ability to recreate an optimal cellular microenvironment is critical to understand neuronal behavior and functionality in vitro. An organized neural extracellular matrix (nECM) promotes neural cell adhesion, proliferation and differentiation. Here, we expanded previous observations on the ability of nECM to support in vitro neuronal differentiation, with the following goals: (i) to recreate complex neuronal networks of embryonic rat hippocampal cells, and (ii) to achieve improved levels of dopaminergic differentiation of subventricular zone (SVZ) neural progenitor cells. Methods: Hippocampal cells from E18 rat embryos were seeded on PLL- and nECM-coated substrates. Neurosphere cultures were prepared from the SVZ of P4-P7 rat pups, and differentiation of neurospheres assayed on PLL- and nECM-coated substrates. Results: When seeded on nECM-coated substrates, both hippocampal cells and SVZ progenitor cells showed neural expression patterns that were similar to their poly-L-lysine-seeded counterparts. However, nECM-based cultures of both hippocampal neurons and SVZ progenitor cells could be maintained for longer times as compared to poly-L-lysine-based cultures. As a result, nECM-based cultures gave rise to a more branched neurite arborization of hippocampal neurons. Interestingly, the prolonged differentiation time of SVZ progenitor cells in nECM allowed us to obtain a purer population of dopaminergic neurons. Conclusions: We conclude that nECM-based coating is an efficient substrate to culture neural cells at different stages of differentiation. In addition, neural ECM-coated substrates increased neuronal survival and neuronal differentiation efficiency as compared to cationic polymers such as poly-L-lysine.

The scientific legacy of the "Instituto Eduardo Torroja" in Bilbao (1960-1980)

By means of this analysis, we have endeavored to evaluate and understand both the influence that the IETcc started to bear on scientific progress in Bilbao, mainly during the 1960s and the 1970s, as well as the determined efforts of the local financial and industrial elite of the time to transform Bilbao into the great metropolis of the north, i.e. the economic capital of that part of Spain, using as a model, among other metropolises, New York, the financial capital of America, and Pittsburg, the industrial capital. The various means to accomplish this have been studied: from the institutions of investigation, exposition and information which would initiate the longed for scientific progress, to the pathways for reproducing the fascinating American way.

"Heroes" and "Villains" of World History across Cultures

Emergent properties of global political culture were examined using data from the World History Survey (WHS) involving 6,902 university students in 37 countries evaluating 40 figures from world history. Multidimensional scaling and factor analysis techniques found only limited forms of universality in evaluations across Western, Catholic/Orthodox, Muslim, and Asian country clusters. The highest consensus across cultures involved scientific innovators, with Einstein having the most positive evaluation overall. Peaceful humanitarians like Mother Theresa and Gandhi followed. There was much less cross-cultural consistency in the evaluation of negative figures, led by Hitler, Osama bin Laden, and Saddam Hussein. After more traditional empirical methods (e.g., factor analysis) failed to identify meaningful cross-cultural patterns, Latent Profile Analysis (LPA) was used to identify four global representational profiles: Secular and Religious Idealists were overwhelmingly prevalent in Christian countries, and Political Realists were common in Muslim and Asian countries. We discuss possible consequences and interpretations of these different representational profiles.
