En meningsfull tilnærming til logaritmer En designstudie om introduksjon av logaritmer gjennom repetert divisjon

2015

Masteroppgave matematikkdidaktikk- Universitetet i Agder, 2015 This study is about finding a more effective method of introducing logarithms. As part of my study, I developed a new teaching material. The definition of logarithms in the new material is based on repeated division in the same way powers can be viewed as repeated multiplication. I have formulated the following research questions: 1) What are the characteristics of an effective method of teaching logarithms with regard to conceptual understanding? 2) Is the method where students are being introduced to logarithms through repeated division better than through the definition the Norwegian teaching materials to the greatest extent …
