Aiemmissa tutkimuksissa on todettu, ett\u00e4 representaatioiden osaaminen on edellytys fysiikan k\u00e4sitteiden oikealle ymm\u00e4rrykselle. Fysiikan opiskelussa saattaa my\u00f6s t\u00f6rm\u00e4t\u00e4 tilanteeseen, jossa oma tieto asiasta on ristiriidassa yleisesti hyv\u00e4ksytyn teorian kanssa. N\u00e4iden virheellisten ennakkok\u00e4sitysten on todettu olevan merkitt\u00e4v\u00e4ss\u00e4 osassa fysiikan opiskelussa. T\u00e4ss\u00e4 tutkimuksessa analysoitiin kahdelle lukioryhm\u00e4lle tehdyn interventiotutkimuksen vastausaineistoa, joista pyrittiin selvitt\u00e4m\u00e4\u00e4n opiskelijoiden virheellisten ennakkok\u00e4sitysten yleisyytt\u00e4 sek\u00e4 representaatioiden osaamista Newtonin mekaniikassa. Tarkoituksena oli my\u00f6s selvitt\u00e4\u00e4 voisiko jonkin representaatiolajin hallinnasta tehd\u00e4 johtop\u00e4\u00e4t\u00f6ksi\u00e4 opiskelijan yleisest\u00e4 mekaniikan osaamisesta.\n\nOpiskelijoiden yleisarvosana tutkimusaineiston vastauksissa oli kohtalainen. Osasyyn\u00e4 osaamisen heikohkoon tasoon saattoi olla se, ett\u00e4 tutkimus toteutettiin mekaniikan kurssin kuluessa, eik\u00e4 esimerkiksi kurssin loppukokeena. Kurssin p\u00e4\u00e4ttyess\u00e4 mekaniikan asiat olisivat ehk\u00e4 olleet paremmin sis\u00e4istettyin\u00e4.

Yli puolella tutkimukseen vastanneista opiskelijoista esiintyi virhek\u00e4sitys v\u00e4hint\u00e4\u00e4n yhden kerran.\n\nAlle puolet opiskelijoiden virheellisist\u00e4 vastauksista aiheutui t\u00e4m\u00e4n tutkimuksen mukaan representaatioiden puutteellisesta osaamisesta. Suurempana syyn\u00e4 olivat k\u00e4sitteelliset virheet. Representaatiolajeista parhaiten osattiin matemaattinen ja sanalliset teht\u00e4v\u00e4t. Heikoimmin puolestaan vektoriaaliset teht\u00e4v\u00e4t.
