Hur gymnasieläroböcker i fysik behandlar kursplansmål med kvantmekanisk anknytning

Abstract [sv]

Inledningsvis identifieras de mål i kursplanen för fysik B på gymnasieskolan som har kvantmekaniskt innehåll. Syftet med detta arbete är att genom en textanalys utifrån dessa identifierade kursmål, beskriva hur fem gymnasieläroböcker i fysik B tar upp de utvalda målbeskrivningarna. När det gäller hur atomers struktur presenteras, saknar en av böckerna en modern kvantmekanisk beskrivning och tre böcker ger ingen modern kvantmekanisk beskrivning av elektronernas positioner i en atom. Problem med hur spinn ska beskrivas finns överlag i alla böckerna. Alla läroböckerna förankrar sin framställning om sambandet mellan energinivåer och atomspektra i Bohrs atommodell. Alla introducerar också fotonbegreppet på liknande sätt; genom Plancks kvanthypotes och Einsteins ljuspartikelantagande (när han förklarade den fotoelektriska effekten). En sammanfattning av slutsatserna blir att det finns vissa problem med framställningen av kvantmekaniska fenomen i läroböckerna och i synnerhet då det gäller atomers struktur. Detta kan medföra problem när eleverna ska uppfylla kursplanens mål.

Abstract [en]

In the national syllabus for the B-course in physics for the Swedish upper secondary school, there are some stated objectives to be achieved. This paper identifies the objectives that have quantum mechanical related content. The aim is then to analyse how five Swedish textbooks for the B-course in physics for upper secondary school describe physics that are related to these identified objectives. One of the books do not have a quantum mechanical description of the structure of the atom and two of the other books lack a quantum mechanical description of the positions of the electrons inside an atom. There is a general problem how spin is presented. All books describe the electronic energy levels and atomic spectra in the light of the atomic model of Bohr. All books do also introduce the photon in the quantum hypotheses of Planck and Einstein’s explanation of the photoelectric effect. The main conclusion of this study is that there are some problems how the textbooks present physics that have quantum mechanical related objectives in general, but in particular those parts that are related to the atomic structure. This can lead to problems for the students to fulfil the goals in the syllabus.
