On pointe souvent le fait que les manuels scolaires alourdissent les cartables des élèves. Ils pèsent aussi sur les budgets et ne sont pas simples à renouveler quand les changements de programme scolaire s’accélèrent – en témoignent les débats dans les régions au sujet de l’achat des prochains ouvrages pour le lycée, en phase avec la réforme du bac.

Ouvrage papier regroupant une somme de connaissances d’une discipline, le manuel est une « fausse évidence historique » comme l’a écrit Alain Choppin, pionnier des études à ce sujet. En effet, outil scolaire aux multiples facettes, il se situe à l’interface entre l’institution et les enseignants, entre les élèves et l’enseignant, entre les familles et l’institution. C’est aussi un produit commercial car, en France, l’édition scolaire est un marché économique de premier plan, représentant 14 % du chiffre d’affaires annuel du secteur.

les éditeurs scolaires alertent les pouvoirs publics sur la complexité de renouveler à une telle cadence l’ensemble des manuels. La question du financement est posée dans le premier comme le second degré. Certaines régions envisagent un désengagement dans l’achat des manuels et souhaitent passer au tout numérique afin d’éviter les nouvelles dépenses.

Four databases of citizen science and crowdsourcing projects —  SciStarter, the Citizen Science Association (CSA), CitSci.org, and the Woodrow Wilson International Center for Scholars (the Wilson Center Commons Lab) — are working on a common project metadata schema to support data sharing with the goal of maintaining accurate and up to date information about citizen science projects.  The federal government is joining this conversation with a cross-agency effort to promote citizen science and crowdsourcing as a tool to advance agency missions. Specifically, the White House Office of Science and Technology Policy (OSTP), in collaboration with the U.S. Federal Community of Practice for Citizen Science and Crowdsourcing (FCPCCS),is compiling an Open Innovation Toolkit containing resources for federal employees hoping to implement citizen science and crowdsourcing projects. Navigation through this toolkit will be facilitated in part through a system of metadata tags. In addition, the Open Innovation Toolkit will link to the Wilson Center’s database of federal citizen science and crowdsourcing projects.These groups became aware of their complementary efforts and the shared challenge of developing project metadata tags, which gave rise to the need of a workshop.

All these studies show the consequences of applying a narrow understanding of excellence to evaluate research regardless of the context, for example in terms of country, discipline, and language.

In terms of research subjects or topics, WoS and Scopus focus on molecular biology, traditional genetics, and industry-related consumption, whereas CABI focuses more on productivity, plant nutrition, plant characteristics, and plant protection. The foci of WoS and Scopus seem to be related to the research interests of seed companies and food industry, while the foci of CAB are more related to potential interests of local farmers and communities. In this case, research in journals indexed by WoS and Scopus seems to better cover the interests of industrial stakeholders than the interests of small, poorer farmers.

Despite marketing claims that some television programs and DVDs help infants and toddlers learn, recent studies show that TV provides only empty calories for a child’s growing brain. The following research brief reviews the evidence that parents and caregivers of young children should take television off the menu.

Pediatricians are firmly against programing modified specifically for young children, particularly when it is utilized to market toys, games, dolls, unhealthy foods and other items to babies. Furthermore, television will discourage and replace reading. Reading needs much more thinking than TV, and we realize that perusing books encourages youngsters’ healthy brain improvement. Kids from families that have the TV on a lot invest less time reading and being read to and are less likely to be able to read.

television is a bad influence on kids, because watching TV at an early age can affect children’s brain development. For instance, the early years of a youngster are important to their development.

Second positive effect of television among children is that they acquire basic languages on it. Studies shows that if they watch educational programs, their tendency is to learn basic shapes, numbers, letters, etc. if their parents guided them (Lemish and Rice, 1986). However, Naigles and Mayeux (2001) found that in certain circumstances children learn words and their meanings from educational programs that are specifically design for them (age, content etc.)

Television has a great benefit among children as they get easily aware and connect about the physical happenings in their modern-faced society (Gunter and McAleer, 1997: xii-xiii).They also stated that television is not ‘one-eyed monster’ who waits to spread evil over the young members of the household. This is an implication that when a child watches a significant program that is – educational, informative, and values-promoted shows will increase their intellectual growth

There are a lot of educational shows which air on TV. It is a proven fact that children learn better using audio-video method instead of the traditional teaching via books. Many research studies have shown that children who watch TV are less violent and perform well in tests and studies as compared to the ones who don’t watch TV. Children who watch educational and informative TV shows develop their brain skills faster and learn things easily as compared to the ones who don’t watch TV. The kids who are going to start their school life get better grades, value their studies when they reach high school and become less aggressive. TV is a great way to remove tiredness and fatigue. We all know kids love cartoons and according to studies, cartoons have a soothing and painkilling effect on children. It helps in removing all the tiredness and all the stress your kid is having from daily school work. We know that there are both pros and cons of everything. We already have listed the positive points of TV and now we will share some negative points of TV with you

Let older kids see things you don't agree with. But then discuss exactly what you don't like with them. Since we won't always be around, we need to make sure to instill critical-thinking skills in our kids.

Kids will be inspired by great historical figures, athletes, or TV stars. Take advantage of that adoration by pointing out their good traits, as in, "George Washington was honest. Honesty is an important quality." Not: "Lying is bad. Children who lie get in trouble."

Reinforce your values. Point out words and behavior in popular TV shows, websites, and music that are both positive and negative examples of what you do and don't want your kids to model. What you say to your child is up to you, but have the discussion.

The natural selection of bad science

The WWARN experience suggests that truly useful data sharing platforms must be thought of as long-term, infrastructural investments; they cannot be thrown up as rapid, project-based responses to funder or journal demands.

the WWARN network published several pooled analyses which established the value of the resource as a source of additional learning. This has encouraged drug developers and global health organisations to begin to request analyses using the database, and has prompted changes to access policies to facilitate use of the resource by all legitimate analysts.

By adopting the study group model, which appealed to data contributors, WWARN was able simultaneously to build up the database and to begin to conduct important pooled analyses that have contributed directly to improvements in global policy.

Box 1 summarises the characteristics of a data sharing platform that has the potential to increase policy-relevant knowledge.

“The fact that [WWARN] has standardised data so that everyone can learn and analyse with the same tools: that is going to be the future, however much people are conservative and reject it and are afraid of it. This will happen, so let's make it useful.”

the team has already begun to adapt the data infrastructure, informatics tools, policies and procedures for other diseases; these efforts demonstrate the time and cost savings achieved by building on the WWARN experience.

What we have seen is that when we have data, some of the data we don't even think have value, [it] may have very great value to other institutions.

At least two of these papers contributed directly to a change in WHO treatment recommendations25.

Furthermore, the JIF –in its normalized variant –seems to differentiate more or less successfully between promising and uninteresting candidates not only in the short term, but also in the long term.

But thegenuine advances achieved during Reconstruction, such as improvedaccess to education, exercise of political rights, and the creation of newblack institutions like independent churches, produced a violent reactionby upholders of white supremacy. During the 1870s, the North retreatedfrom its commitment to equality. In 1877, Reconstruction came to an end.Many of the rights guaranteed to the former slaves were violated in theyears that followed.

Although Reconstruction only lasted from 1865 to 1877, the issuesdebated then forecast many of the controversies that would envelopAmerican society in the decades that followed. The definition ofAmerican citizenship, the power of the federal government and itsrelationship to the states, the future of political democracy in a societymarked by increasing economic inequality—all these were Reconstructionissues, and all reverberated in the Gilded Age and Progressive era thatfollowed.

But just as the American Revolution leftto nineteenth-century Americans the problem of slavery, the Civil Warand Reconstruction left to future generations the challenge of bringinggenuine freedom to the descendants of slavery.

Surprisingly, even publications in prestigious journals or from several independent groups did not ensure reproducibility.

Additional broader impacts will emerge from analyses of the whooping crane dataset. Through collaborations with endangered species biologists in the US Geological Survey, these analyses will have direct relevance to specific management actions for the whooping crane, such as the timing, group size, and composition of crane reintroductions and potentially their training with ultra-light aircraft.

Just as comprehensive datasets of genomic sequence have revolutionalized biological discovery, large-scale quantitative measurements of gene expression and morphology will certainly be of great assistance in enabling computational embryology in the future. Such datasets will form the essential basis for systems level, computational models of molecular pathways and how gene expression concentrations and interactions alter to drive changes in cell shape, movement, connection, and differentiation. In this review, we discuss the strategies and methods used to generate such datasets.
