Geen stemkastje, maar gewoon, met je telefoon
Antoine van Dinter wijst in zijn blog Frans & ICT op het gebruik van SMS om leerlingen actief te laten deelnemen aan de les. Niet via speciale en vaak dure stemkastjes, maar gewoon mbv het communicatiemiddel dat iedere jongere dag en nacht bij zich heeft, de mobiele telefoon. Het enige nadeel is dat er aanspraak wordt gemaakt op het beltegoed.

Correlatie tussen citaties en downloads
De impact van een wetenschappelijk artikel wordt standaard gemeten aan de hand van het aantal citaties. Online tijdschriften bieden daarnaast de mogelijkheid om ook het aantal unieke downloads van een artikel vast te stellen. Andrew B. Watson beschrijft de mate van correlatie tussen de twee meetmethoden in zijn artikel Comparing citations and downloads for individual articles in het Journal of Vision.
Watson concludeert:
1. Overall correlation between total downloads and total citations of Journal of Vision articles is 0.74.
2. Citations and downloads increase with article age in a characteristic way, but relative to downloads, citations are delayed by about 2 years and reduced by a factor of about 45.
3. For papers published in a single year, the correlation is as high as 0.8, and usually above 0.6.
4. The correlation between age-normalized statistics of DemandFactor (downloads/year) and CiteFactor (citations/year) is about 0.62.
5. Download statistics provide a useful indicator, two years in advance, of eventual citations. Downloads are also a useful measure in their own right of the interest and significance of individual articles.

Publish or perish: Online reformation to the rescue?
Videolecture mbv Mediasite van Carl F. Berger, Emeritus hoogleraar aan de University of Michigan-Ann Arbor
"Online scholarly and research publishing isnt new. Low cost, quick access, and high positive search rates promise easy success, yet high failure rates abound. Should such publishing be abandoned, as one publishers association has advised? Or are there new factors that could make an online publishing reformation work? We’ll explore ideas for using promising new tools from the digital native, the millennium instructor, and the hooked-in editor. With a dash of economic models, a measure of credibility, and solid dose of sustainability, there is hope for those who must publish or perish, and, more importantly, for all in our profession".
