1. Relationer eller operationer - två sidor av samma mynt : Elevers utforskande av en del-helhetsmodell som redskap för att urskilja relationer i additiva strukturer
Sammanfattning : Syftet med denna licentiatuppsats är att pröva en specifik strukturell modell som stöd för elevers utforskande av relationer mellan tal i additiva strukturer även när negativa tal är inkluderade. En intention är att resultatet ska kvalificera undervisningen och utgöra ett stöd vid planering och genomförande av en undervisning avseende ekvationer med additiv struktur utifrån algebraisk undervisning som alternativ till att i första hand finna en lösning med stöd av regler och procedurer.
