Les savoirs scientifiques relatifs aux végétaux, conceptions des élèves, difficultés d’apprentissage et problématisation

Francis ROUQUET

Les connaissances relatives aux végétaux visées par les programmes scolaires : quelles difficultés des élèves sont constatées en fin de curriculum scolaire ? Quelle part de la transposition didactique ? Force est de constater que, si en fin de cursus scolaire, les conceptions des élèves relatives aux végétaux s’éloignent des connaissances visées par les programmes officiels, c’est que le concept des végétaux est complexe et qu’ils ont une place particulière dans le vivant. Par ailleurs, différents obstacles épistémologiques expliquent les difficultés rencontrées par les élèves face aux apprentissages. Le recueil de données réalisé sur des élèves de terminales scientifiques permet d’envisager un état des lieux des conceptions des élèves (étude quantitative). Le cadre théorique de la problématisation éclairera la construction de savoirs problématisés face aux résistances constatées (étude qualitative).
