Varför flera val?

\n Lässtöd fungerar olika för olika elever. Därför går det att kombinera bionic reading med större text, smalare radlängd och lugnare bakgrund.\n

Bra att börja med

\n Testa först Atkinson Hyperlegible, fontstorlek runt 20 till 24 px, vänsterställd text och radavstånd runt 1.7 till 1.9.\n

Tips till lärare

\n Låt eleven jämföra två läslägen och beskriva vilket som känns mest hållbart över tid. Det brukar ge bättre träffsäkerhet än att vuxna gissar.\n
