KI-forskare: porta skolpolitiker som vill ge hälsofarliga läsplattor – utan bevisat pedagogiskt värde – till eleverna
23 Jan, 2014 By
Tack vare den s.k. Pisa-undersökningen vet vi nu: Resultaten rasar i den svenska skolan. Något är fel. Regeringen svarar med att tvinga alla elever att gå igenom denna skola ytterligare ett år samt igångsätter en rad med andra panikåtgärder. Men räkna inte med att skolorna nu ska få arbetsro, så att de kan luska ut hur de får saker att fungera och avvecklar de hjälpmedel och administrativa ‘tömmar’ som inte gör det.

Skolorna har på några få år utsatts för mängder av förändringar och fått nya uppdrag, kontrolluppgifter och ny administration. En del är bra, en del dåligt. Man har bl.a. satsat enormt mycket på den datoriserade undervisningen där eleverna via sina appar, mobiltelefoner och läsplattor ska inhämta ny kunskap. Pedagogikens förnyare har tagit bort läroböcker och pennor, svarta tavlor och pekpinnar, och istället ersatt dem med de nya trådlösa läsplattorna och mobilerna. Andra, såsom jag själv, har många gånger – oftast helt ohörda – höjt ett varnande pedagogiskt finger.
Idag är det mycket svårt att vara lärare och ta ansvar för undervisningen i klassrum där elevernas mobiltelefoner ideligen ringer, SMS skickas fram och tillbaka, och via sina iPhones och iPads surfar de hela tiden på nätet eller spelar olika spel. Allt detta när de egentligen skall arbeta med sina skoluppgifter.
I Sverige har man haft flera fall där lärare tillrättavisats därför de “kränkt elevernas integritet” när de tagit från dem sina mobiltelefoner, och andra lärare har anmälts för att de varit för stränga mot eleverna och inte tillåtit de att göra vad de önskat på timmarna. Samtidigt som det skett har Sverige – som är ett av de mest datortäta skolländerna i världen – rasat avseende läs-, skriv- och matematikkunskaper, man har idag inte råd att anställa tillräckligt med personal, och det har t.o.m. föreslagits att “skoltrötta” elever ska slippa 2/3 av sin gymnasieutbildning. Så de nya hjälpmedlen imponerar inte – det verkar snarare som om vi borde lägga pengarna på välutbildade lärare med gammaldags läromedel.
Vad man samtidigt sett är en tendens till att elever på alternativa skolor, såsom Waldorf, Montessori och Reggio Emilia, tycks klara sig något bättre och mognar mentalt snabbare – och det är väldigt intressant eftersom dessa skolor av tradition – inte alls använder sig av datorer och liknande till samma grad.
Barn troligen känsliga för pulsad mikrovågsstrålning från iPads och routers
Dessa nya trådlösa hjälpmedel översvämmar numera skolor och hem. Exempel på sådana strålkällor är trådlösa routers, datorer med trådlösa nätverkskort, trådlösa fasta telefoner, läsplattor (som iPad), mobiltelefoner, osv. Sedan flera år tillbaks finns det samtidigt bevis för att exponering från deras elektromagnetiska fält kan orsaka allvarlig biologisk påverkan och hälsoeffekter. Mot denna bakgrund har många likt jag själv protesterat, bl.a. föräldrar tillsammans med lärare och skolpersonal i Köping som i Bärgslagsbladet den 18/4, 2012, under rubriken “Nej till trådlöst i skolan” försökte sätta ned foten.
Det finns numera många vetenskapliga belägg för att barn sannolikt är mer sårbara för pulsad mikrovågsstrålning än vuxna, och ny forskning visar bland annat på allvarliga effekter på beteende och inlärningsförmåga. Det råder en allmän enighet bland forskare om att elektromagnetiska fält penetrerar hjärnan hos barn mer än hos vuxna eftersom barnskallar är tunnare. Det råder också en bred enighet om att barn är mer utsatta för skadeeffekter från strålning eftersom deras kroppar är under utveckling.
Barn är inte ”små vuxna”!
Europarådets miljöutskott kräver kraftfulla åtgärder för att skydda allmänheten mot mobilstrålning
WHO har 2011 klassificerat elektromagnetiska fält från trådlös informationsteknologi som möjligt cancerframkallande. Europarådets miljöutskott kräver i sin resolution nr. 1815 från maj 2011 kraftfulla åtgärder för att skydda allmänheten mot mobilstrålningens skadeverkningar, bl.a. vill man ha ett förbud mot mobiltelefoni och trådlöst internet i skolor med hänsyn till barns hälsa. Man vill också sänka gränsvärdet för mobiltelefoni kraftigt, allt detta helt i enighet med Seletunrapportens krav från 2010.
I denna yrkar en internationell grupp vetenskapsmän om stopp för vidare utbyggnad av trådlösa system och kräver nya gränsvärden.
Gruppen, The Seletun Scientific Panel, publicerade i februari 2010 en resolution med en lång rad gemensamma ståndpunkter och rekommendationer, baserade på en genomgång av den då tillgängliga forskningen om hälsoeffekter av elektromagnetiska fält. Sedan dess har det kommit ännu fler rapporter…
Svenska Strålsäkerhetsmyndigheten (SSM) vilseleder
Ibland ser man i debatten att någon – oftast från en strålsäkerhetsmyndighet – hävdar att det inte är någon fara, “strålningen är så svag”. Svag i förhållande till vad, frågar jag mig? Idag sitter barn i strålningsnivåer som med lätthet kan vara 1.000.000.000.000.000.000 gånger högre än vår naturliga bakgrundsstrålning. Hur blev ett sådant tal “så svagt”?
Använder barn en bärbar dator för att ladda ner från trådlöst Internet är de utsatta för lika mycket strålning (omkring 1.000 μW/m2 och däröver) som om de var nära en basstation för mobiltelefoni (50-100 meter). Det finns många föräldrar som inte är medvetna om detta. Siffrorna är inte tagna ur luften utan hämtade från den officiella mätning som den norska Post- och Telestyrelsen gjort, bl.a. i skolor i Oslo. Oavsett om det handlar om basstationer, trådlösa nätverk eller mobiltelefoner, så är det samma typ av strålning vi talar om (i intervallet 1-2,5 GHz).
Autism och ADHD-liknande beteenden
En grupp forskare i Kalifornien genomförde nyligen en stor studie av mobilanvändning hos gravida kvinnor. De tittade på alla barn som var född i Danmark ett visst år, och intervjuade mödrarna om sin mobilanvändning under graviditeten. De frågade också om barns mobilanvändning och beteende.
Det visade sig, till forskarnas förvåning, att de mödrar som hade använt mobiltelefon mest under graviditeten hade den största risken att få barn med beteendesvårigheter.
Det handlade om både autism och ADHD-liknande beteenden. Riskökningen var statistiskt säkerställda. Risken ökade dessutom ytterligare om barnet själv använde mobiltelefon.
[Divan H A, Kheifets L, Obel C, Olsen J (2008) “Prenatal and postnatal exposure to cell phone use and behavioral problems in children”, Epidemiology 2008; 19: 523-529]
Symptom: Huvudvärk, onormal trötthet och irritation
En sådan studie är kanske inte tillräcklig för att draga slutsatsen att elektromagnetiska fält är farliga för barn. Tyska forskare ville därför mäta stråldosen som barn och ungdomar utsätts för i det dagliga livet. De bad ca. 3.000 barn och ungdomar i Bayern att gå omkring med en dosimeter på sig från morgon till kväll. Dosimetrarna mätte strålningen från mobiltelefoner, basstationer och trådlösa nätverk.
Det visade sig att den fjärdedel av barnen som varit mest utsatta för strålning, hade mer koncentrationsproblem på kvällen än resten av barnen. Samma grupp hade också mer huvudvärk och var mer irriterade än andra ungdomar.
Resultaten var återigen statistiskt säkerställda. [Heinrich S, Thomas S, Heumann C, von Kries R, Radon K (2010) “Association between exposure to radiofrequency electromagnetic fields assessed by dosimetry and acute symptoms in children and adolescents: a population based cross-sectional study”, Environmental Health 2010; 9: 75-83]
Så frågan är vilken mekanism som kan förklara dessa symtom hos barn och ungdomar. Forskarna Buchner & Eger i Tyskland mätte nivåerna av stresshormoner hos 60 boende i ett område innan man monterade in en basstation. Därefter uppmättes de igen efter sex månader och återigen efter ett och ett halvt år efter det att antennen togs i drift.
Det visade sig att människorna hade mycket högre nivåer av stresshormonerna adrenalin och noradrenalin sex månader efter det att basstationen tagits i drift, och efter ytterligare ett år hade situationen inte förbättrats. Att leva med en sådan ständig stressituation i kroppen är självklart skadligt för hälsan.
[Buchner K, Eger H, “Veränderung klinisch bedeutsamer Neurotransmitter unter dem Einfluss modulierter hochfrequenter Felder - Eine Langzeiterhebung unter lebensnahen Bedingungen”, Umwelt-Medizin-Gesellschaft 2011; 24: 44-57.]
Tro nu inte att detta bara handlar om barn. Nej, även foster påverkas markant och på ett synnerligen skrämmande vis. Forskarna Jing, m. fl., vid Department of Public Health, Shandong University i Kina, har studerat påverkan av mobilstrålning på gravida råttors foster. Forskarna mätte förändringar på både nervcellers signalämnen samt effekter på antioxidativa enzym vilka skall skydda våra celler från oxidativ stress.
Slutsats: Mobilstrålningen under graviditeten gav upphov till skador på fostrens hjärnor! De föddes alltså redan hjärnskadade. Vilka mammor och pappor vill det?
[Jing J, Yuhua Z, Xiao-Qian Y, Rongping J, Dong-Mei G, Xi C, “The influence of microwave radiation from cellular phone on fetal rat brain”, Electromagn Biol Med 2012; 31: 57-66.]
Elever och lärare rapporterar allt oftare onormal trötthet i sin arbetsmiljö, och man kan idag inte avfärda misstankarna om att exponering från trådlösa nätverk kan spela en roll för detta. Det är därför mycket viktigt att vi nu säkerställer att trådlösa nätverk från förskolor och skolor inte i sig utgör betydande och onödiga risker för våra barns och lärares hälsa. Ämnet är akademiskt inte speciellt komplicerat, men kan för en lekman framstå som svårbedömt. Bristen på kunskap beror idag uteslutande på bristande forskningsresurser, ej på bristande idéer, hypoteser, teorier eller intresse.
Försiktighetsprincipen måste tillämpas
Baserat på ovanstående information har organisationen Folkets Strålevern i Norge,www.stralevern.no, uppmanat föräldrar att skriva på ett formellt avtal där man som förälder inte ger sitt samtycke till att skola eller förskola utsätter deras barn för mikrovågsstrålning från trådlös kommunikationsteknik varken i klassrummet eller inomhus i allmänhet. Som förälder uppmanas man till att också kräva att skolan/förskolan vidtager försiktighetsåtgärder för att minimera strålningsexponeringen, och att trådbundna lösningar för datanät och inomhustelefoni genast återanskaffas. Man uppmanas också att kräva svar på vem som är ansvarig om barnet skadas p.g.a. strålningsexponeringen.
Men vi måste nu snabbt bestämma oss! Antingen ska vi i Sverige enbart ha framtida ”konstnärstyper” som springer runt i samhället, hej vilt, kreativa som sjutton men helt omöjliga att sätta vid spakarna på ett flygplan eller ansvara för säkerheten vid ett kärnkraftverk. Eller också ska vi ha en befolkning som helt jämlikt bibringas samtliga grunder för att fungera i vårt samhälle, på alla de olika poster vi anser oss behöva, och där vi inte accepterar matte-, läs- och skrivsvårigheter som enbart beror på att undervisningen skötts av ej behörig personal, via underliga ”appar” och i ett datoriserat pedagogiskt kaos.
Men vår utbildningsminister Jan Björklund har nu istället tillsatt en rådgivande internationell expertgrupp (en s.k. ”skolkommission”), en ny myndighet (ett ”skolforskningsinstitut”) som skall ”forska” på allt detta, samt avser att också skapa ett svenskt utbildningsråd. Han talar dessutom om diverse nya utredningar och nya reformer.
Vi behöver inte mer forskning!
Det enda som behövs är behörig personal med god lön som får arbeta i lugn och ro utan att hotas, trakasseras eller kränkas. Deras arbete med eleverna ska vara i enlighet med traditionella effektiva pedagogiska modeller, med bevisat pedagogiska hjälpmedel, lugn och ro i klassen, koncentration, glädje, entusiasm, undervisning istället för spel och mobilsurfning, uppgifter anpassade till var och ens förmåga, och krav på lärare och elever i förhållande till framtida ansvarsnivåer. (I den offentliga debatt som varit hörde eller läste jag dock ingenstans att man ska satsa nytt på själva skolan, lärarna, utbildningen eller de ofta usla skollokalerna samt den salmonella-smittade skolmaten utan dessa lämnas utan åtgärd. Låter som något ur en Hasse å Tage-revy, eller hur!)
Peter Kadhammar på Aftonbladet konstaterar i sin utmärkta kolumn från den 17/1 2014 att ”I kunskapssamhället har läsförmågan gått förlorad”. Som jag många gånger har påpekat har detta skett trots (!) de enorma mängder av elektroniska prylar som införts och numera används i våra svenska skolor. Alla iPads, WiFi, ”surfa på websidor”, dataspel, laptops, textmeddelanden som sänds under lektionstid, smarta telefoner, etc., verkar alltså inte ha gjort sitt förmodat pedagogiska jobb?
Det räcker nu. Det behövs lugn och ro i klassrummet. Lägg bort läsplattan och mobilen och porta skolpolitiker som vill satsa pengar på obevisat pedagogiska prylar som dessutom troligen är rent hälsofarliga.

Schools have a few years undergone a multitude of changes and given new assignments , monitoring data and new administration . Some are good, some bad.

Children probably sensitive to pulsed microwave radiation from iPads and routers
barn_med_ipadDessa new wireless devices now flooding the schools and homes. Examples of such sources are wireless routers, computers with wireless network cards , wireless landline phones , tablets ( like the iPad ) , mobile phones, etc. . Several years ago, there is also evidence that exposure from their electromagnetic fields can cause serious biological effects and health effects. Against this backdrop, many like myself protested , including parents together with teachers and school staff in Koping as in Bärgslagsbladet 18 /4, 2012, under the title "No wireless at school " tried to put his foot down .
There are now numerous scientific evidence that children are likely to be more vulnerable to pulsed microwave radiation than adults , and new research shows, among other serious effects on behavior and learning ability. There is general agreement among scientists that electromagnetic field penetrates into the brain in children more than in adults because children call is thinner. There is also a broad consensus that children are more vulnerable to adverse effects from radiation because their bodies are developing.
Children are not " little adults " !
Council of Europe 's Environment Committee calls for strong measures to protect the public against mobile phone radiation
WHO has 2011 classified electromagnetic fields from wireless information as possible carcinogens. Council of Europe 's Environment Committee in its Resolution no. 1815 from May 2011 strong measures to protect the public against mobile harmful effects of radiation , including it wants a ban on mobile phones and wireless internet in schools with regard to children's health. It also wants to reduce the level of mobile sharply, all this completely in agreement with Seletunrapportens requirements from 2010.
In this claim , an international group of scientists on a stop to further expansion of wireless systems and require new limits.
The group , The Seletun Scientific Panel , published in February 2010 a resolution with a wide range of common positions and recommendations , based on a review of the then available research on the health effects of electromagnetic fields. Since then there have been many more reports …
Swedish Radiation Safety Authority ( SSM) misleads
Sometimes you see in the debate that someone - usually from a radiation safety - claims there is no danger, " the radiation is so weak." Weak compared to what , I wonder ? Today there are children in radiation levels that could easily be 1,000,000,000,000,000,000 times higher than our natural background radiation. How did such a speech " so weak" ?
Uses child a laptop for downloading from wireless Internet is vulnerable to the same amount of radiation ( about 1,000 μW/m2 and above) as if they were near a cellular base station (50-100 meters). There are many parents who are not aware of this. The figures are not taken from the air, but taken from the official measurement by the Norwegian Post and Telecommunications Agency made , including in schools in Oslo. Whether it 's about base stations, wireless or cell phones, so it is the same type of radiation we're talking about ( in the range 1-2.5 GHz) .
Autism and ADHD -like behaviors
A group of researchers in California recently conducted a large study of mobile phone use in pregnant women. They looked at all the kids who were born in Denmark in a given year , and interviewed the mothers about their mobile phone use during pregnancy. They also asked about the child's mobile usage and behavior.
It turned out , to the researchers' surprise, that the mothers who had used mobile phones the most during pregnancy had the greatest risk of having children with behavioral difficulties .
It was about both autism and ADHD -like behaviors . The increase in risk was statistically significant . The risk also increased further if the child himself used cell phone.
[ Divan HA, Kheifets L , Obel C , Olsen J (2008) " Prenatal and postnatal exposure to cell phone use and behavioral problems in children" , Epidemiology, 2008 , 19 : 523-529 ]
Symptoms: Headache, fatigue and abnormal irritation
Such a study might not be sufficient to conclude that electromagnetic fields are dangerous to children . German researchers wanted to measure the radiation dose that children and adolescents are exposed to in daily life . They asked about . 3,000 children and youth in Bavaria to walk around with a dosimeter on from morning to night. The dosimeters measured the radiation from cell phones, base stations and wireless networks.
It turned out that the quarter of the children who were most exposed to radiation had more concentration problems at night than the rest of the kids. The same group also had more headaches and were more irritated than other young people.
The results were again statistically significant . [ Heinrich S, Thomas S, Heumann C , von Kries R , Radon K (2010) " Association between exposure to radiofrequency electromagnetic fields were assessed by dosimetry and acute symptoms in children and adolescents : a population- based cross- sectional study ," Environmental Health 2010 , 9 : 75-83 ]
So the question is what mechanism can explain these symptoms in children and adolescents. Scientists Buchner & Eger in Germany measured levels of stress hormones in 60 residents in an area before mounted in a base station. Then they were measured again after six months and again after one and a half years after the antenna became operational
It turned out that people had much higher levels of stress hormones adrenaline and noradrenaline six months after the base station becomes operational, and after another year , the situation had not improved. Living with such a constant stress situation in the body is obviously harmful to health.
[ Buchner K , Eger H, " Veränderung klinisch bedeutsamer Neurotransmitter unter dem Einfluss modulierter hochfrequenter Felder - Eine Langzeiterhebung unter lebensnahen Bedingungen " Umwelt - Medizin -Gesellschaft 2011: 24 : 44-57 . ]
Do not think this is just about the kids. No, even fetuses affected significantly and in a particularly scary way. Scientists Jing, et al. , The Department of Public Health , Shandong University, China , has studied the impact of mobile phone radiation on pregnant rat fetuses. The researchers measured changes in both neurons neurotransmitters and effects on antioxidant enzyme which will protect our cells from oxidative stress.
Conclusion : Mobile phone radiation during pregnancy resulted in damage to the fetal brains! They were born is already brain-damaged . What moms and dads want it?
[ Jing J , Yuhua Z , Xiao- Qian Y, Rongping J , Dong- Mei G, Xi C , " The influence of microwave radiation from cellular phone on fetal rat brain ," Electromagn Biol Med 2012 ; 31 : 57-66 . ]
Students and teachers reported more frequently abnormal fatigue in their working environment, and you can currently not dismiss suspicions that exposure from wireless networks can play a role in this. It is therefore very important that we ensure that wireless networks from kindergartens and schools are not in themselves significant and unnecessary risks for our children's and teachers' health. The subject is academically not very complicated, but can be for a layman seem difficult to assess. The lack of knowledge is due today exclusively on the lack of research resources, not a lack of ideas, hypotheses, theories or interest.
The precautionary principle must be applied
Based on the above information , the organization People Straw liver in Norway, www.stralevern.no , urged parents to sign a formal agreement where a parent does not consent to that school or nursery expose their children to microwave radiation from wireless communication technology either in the classroom or indoors in general. As a parent, you are encouraged to also require that the school / preschool commits an precautions to minimize radiation exposure , and to wired solutions for data networking and telephony indoors immediately replenished . You are also encouraged to demand answers on who is responsible for the child damaged by radiation exposure.
But we must now quickly decide ! Either in Sweden we only have future " artist types " running around in the community, wildly creative as heck but totally impossible to put at the controls of an airplane, or be responsible for the safety of a nuclear power plant . Or should we have a population that is completely egalitarian imparted all the grounds to work in our society , at all the different items we feel we need , and where we do not accept math , reading and writing that is solely due to the teaching handled by unauthorized personnel , through the strange "apps " and in a computerized educational chaos.
But our education minister Jan Björklund has instead appointed an advisory of international experts (called "school commission " ) , a new agency ( an " educational research " ) to be " researching " all this, and intends to create a Swedish Education . He will also speak about the various new investigations and new reforms.
We do not need more research!
The only thing needed is a competent staff with good pay and can work in peace without being threatened , harassed or violated. Their work with students shall be in accordance with traditional effective educational models , with proven pedagogical aids , peace and quiet in class, concentration , joy, enthusiasm , teaching instead of gaming and mobile browsing, information tailored to each individual's ability , and demands on teachers and students in relation to future levels of responsibility. ( In the public debate that has been heard or I read Nowhere, however, that one should bet again on the school, the teachers , the education or the often poor school facilities and the salmonella - contaminated school lunches , but these are left unattended . Sounds like something out of a Hasse on Tage revue , right !)
Peter Kadhammar at Aftonbladet notes in his excellent column from the 17/1 in 2014 that " In the knowledge society have literacy skills have been lost ." As I have pointed out many times has this happened in spite of (!) The vast amounts of electronic gadgets introduced and is now used in our Swedish schools. All iPads , WiFi, " surf the web pages " , computer games, laptops , sending text messages during class , smart phones, etc. , do not seem to have done their supposedly teaching job?
It is enough now. We need peace and quiet in the classroom. Put away the e-reader and mobile and porta school politicians who want to spend money on unproven educational gadgets that also probably is purely a health hazard .

[ Heinrich S, Thomas S, Heumann C , von Kries R , Radon K (2010) " Association between exposure to radiofrequency electromagnetic fields were assessed by dosimetry and acute symptoms in children and adolescents : a population- based cross- sectional study ," Environmental Health 2010 , 9 : 75-83 ]
So the question is what mechanism can explain these symptoms in children and adolescents. Scientists Buchner & Eger in Germany measured levels of stress hormones in 60 residents in an area before mounted in a base station. Then they were measured again after six months and again after one and a half years after the antenna became operational
It turned out that people had much higher levels of stress hormones adrenaline and noradrenaline six months after the base station becomes operational, and after another year , the situation had not improved. Living with such a constant stress situation in the body is obviously harmful to health.

Do not think this is just about the kids. No, even fetuses affected significantly and in a particularly scary way. Scientists Jing, et al. , The Department of Public Health , Shandong University, China , has studied the impact of mobile phone radiation on pregnant rat fetuses. The researchers measured changes in both neurons neurotransmitters and effects on antioxidant enzyme which will protect our cells from oxidative stress.
Conclusion : Mobile phone radiation during pregnancy resulted in damage to the fetal brains! They were born is already brain-damaged . What moms and dads want it?

Students and teachers reported more frequently abnormal fatigue in their working environment, and you can currently not dismiss suspicions that exposure from wireless networks can play a role in this. It is therefore very important that we ensure that wireless networks from kindergartens and schools are not in themselves significant and unnecessary risks for our children's and teachers' health. The subject is academically not very complicated, but can be for a layman seem difficult to assess. The lack of knowledge is due today exclusively on the lack of research resources, not a lack of ideas, hypotheses, theories or interest.
The precautionary principle must be applied
Based on the above information , the organization People Straw liver in Norway, www.stralevern.no , urged parents to sign a formal agreement where a parent does not consent to that school or nursery expose their children to microwave radiation from wireless communication technology either in the classroom or indoors in general. As a parent, you are encouraged to also require that the school / preschool commits an precautions to minimize radiation exposure , and to wired solutions for data networking and telephony indoors immediately replenished . You are also encouraged to demand answers on who is responsible for the child damaged by radiation exposure.
But we must now quickly decide ! Either in Sweden we only have future " artist types " running around in the community, wildly creative as heck but totally impossible to put at the controls of an airplane, or be responsible for the safety of a nuclear power plant . Or should we have a population that is completely egalitarian imparted all the grounds to work in our society , at all the different items we feel we need , and where we do not accept math , reading and writing that is solely due to the teaching handled by unauthorized personnel , through the strange "apps " and in a computerized educational chaos.
But our education minister Jan Björklund has instead appointed an advisory of international experts (called "school commission " ) , a new agency ( an " educational research " ) to be " researching " all this, and intends to create a Swedish Education . He will also speak about the various new investigations and new reforms.
We do not need more research!
The only thing needed is a competent staff with good pay and can work in peace without being threatened , harassed or violated. Their work with students shall be in accordance with traditional effective educational models , with proven pedagogical aids , peace and quiet in class, concentration , joy, enthusiasm , teaching instead of gaming and mobile browsing, information tailored to each individual's ability , and demands on teachers and students in relation to future levels of responsibility. ( In the public debate that has been heard or I read Nowhere, however, that one should bet again on the school, the teachers , the education or the often poor school facilities and the salmonella - contaminated school lunches , but these are left unattended . Sounds like something out of a Hasse on Tage revue , right !)
Peter Kadhammar at Aftonbladet notes in his excellent column from the 17/1 in 2014 that " In the knowledge society have literacy skills have been lost ." As I have pointed out many times has this happened in spite of (!) The vast amounts of electronic gadgets introduced and is now used in our Swedish schools. All iPads , WiFi, " surf the web pages " , computer games, laptops , sending text messages during class , smart phones, etc. , do not seem to have done their supposedly teaching job?
It is enough now. We need peace and quiet in the classroom. Put away the e-reader and mobile and porta school politicians who want to spend money on unproven educational gadgets that also probably is purely a health hazard .

KI researchers : porta school politicians who want to give hazardous e-readers - but proven educational value - for students
January 23, 2014 By Admin
Olle_Johansson - Photo - Ida_NordlanderTack to the so-called PISA survey , we now know : The results rages in Swedish schools. Something is wrong . The government responds by forcing all students to go through this school another year and initiates a series of other panic measures. But do not expect that schools will now be able so that they can figure out how to get things to work and dismantle the facilities and administrative ' reins ' that do not.

Schools have a few years undergone a multitude of changes and given new assignments , monitoring data and new administration . Some are good, some bad. Those include invested an enormous amount of computerized teaching where students via their apps, mobile phones and tablets will gain new knowledge . Pedagogy renovator has deleted textbooks and pencils , blackboards , and pointers , and instead replaced them with the new wireless e-readers and cell phones . Others, such as myself, have many times - usually completely unheard - raised a warning finger educational .
Today it is very difficult to be a teacher and take responsibility for teaching in the classroom where students' cell phones constantly ringing , text messages sent back and forth , and through their iPhones and iPads surfing the entire time online or playing games. All this when they really should work on their school assignments .
In Sweden , there have been several cases where the teacher reprimanded because they "violated the students ' privacy ' when they have taken from them their cell phones, and other teachers have been notified that they have been too strict with students and not allowed they to do what they wanted on hours. While there has been Sweden - which is one of the most frequent computer school countries in the world - raged regarding reading, writing and math skills, man today can not afford to hire enough staff, and it has even suggested that " tired of school " students will not have 2/3 of their secondary education . So the new tools do not impress - it just seems like we should be spending money on well-trained teachers with old teaching materials.
What to simultaneously seen is a tendency for students in alternative schools such as Waldorf, Montessori and Reggio Emilia, seem to fare slightly better and mature mentally faster - and it's very interesting because these schools of tradition - not at all use computers and similar to the same degree .
Children probably sensitive to pulsed microwave radiation from iPads and routers
barn_med_ipadDessa new wireless devices now flooding the schools and homes. Examples of such sources are wireless routers, computers with wireless network cards , wireless landline phones , tablets ( like the iPad ) , mobile phones, etc. . Several years ago, there is also evidence that exposure from their electromagnetic fields can cause serious biological effects and health effects. Against this backdrop, many like myself protested , including parents together with teachers and school staff in Koping as in Bärgslagsbladet 18 /4, 2012, under the title "No wireless at school " tried to put his foot down .
There are now numerous scientific evidence that children are likely to be more vulnerable to pulsed microwave radiation than adults , and new research shows, among other serious effects on behavior and learning ability. There is general agreement among scientists that electromagnetic field penetrates into the brain in children more than in adults because children call is thinner. There is also a broad consensus that children are more vulnerable to adverse effects from radiation because their bodies are developing.
Children are not " little adults " !
Council of Europe 's Environment Committee calls for strong measures to protect the public against mobile phone radiation
WHO has 2011 classified electromagnetic fields from wireless information as possible carcinogens. Council of Europe 's Environment Committee in its Resolution no. 1815 from May 2011 strong measures to protect the public against mobile harmful effects of radiation , including it wants a ban on mobile phones and wireless internet in schools with regard to children's health. It also wants to reduce the level of mobile sharply, all this completely in agreement with Seletunrapportens requirements from 2010.
In this claim , an international group of scientists on a stop to further expansion of wireless systems and require new limits.
The group , The Seletun Scientific Panel , published in February 2010 a resolution with a wide range of common positions and recommendations , based on a review of the then available research on the health effects of electromagnetic fields. Since then there have been many more reports …
Swedish Radiation Safety Authority ( SSM) misleads
Sometimes you see in the debate that someone - usually from a radiation safety - claims there is no danger, " the radiation is so weak." Weak compared to what , I wonder ? Today there are children in radiation levels that could easily be 1,000,000,000,000,000,000 times higher than our natural background radiation. How did such a speech " so weak" ?
Uses child a laptop for downloading from wireless Internet is vulnerable to the same amount of radiation ( about 1,000 μW/m2 and above) as if they were near a cellular base station (50-100 meters). There are many parents who are not aware of this. The figures are not taken from the air, but taken from the official measurement by the Norwegian Post and Telecommunications Agency made , including in schools in Oslo. Whether it 's about base stations, wireless or cell phones, so it is the same type of radiation we're talking about ( in the range 1-2.5 GHz) .
Autism and ADHD -like behaviors
A group of researchers in California recently conducted a large study of mobile phone use in pregnant women. They looked at all the kids who were born in Denmark in a given year , and interviewed the mothers about their mobile phone use during pregnancy. They also asked about the child's mobile usage and behavior.
It turned out , to the researchers' surprise, that the mothers who had used mobile phones the most during pregnancy had the greatest risk of having children with behavioral difficulties .
It was about both autism and ADHD -like behaviors . The increase in risk was statistically significant . The risk also increased further if the child himself used cell phone.
[ Divan HA, Kheifets L , Obel C , Olsen J (2008) " Prenatal and postnatal exposure to cell phone use and behavioral problems in children" , Epidemiology, 2008 , 19 : 523-529 ]
Symptoms: Headache, fatigue and abnormal irritation
Such a study might not be sufficient to conclude that electromagnetic fields are dangerous to children . German researchers wanted to measure the radiation dose that children and adolescents are exposed to in daily life . They asked about . 3,000 children and youth in Bavaria to walk around with a dosimeter on from morning to night. The dosimeters measured the radiation from cell phones, base stations and wireless networks.
It turned out that the quarter of the children who were most exposed to radiation had more concentration problems at night than the rest of the kids. The same group also had more headaches and were more irritated than other young people.
The results were again statistically significant .
