Hur mycket repetition krävs för att behärska något?

Hur mycket repetition krävs för att behärska något?

Under din skoltid, har du någonsin undrat hur många gånger du måste repetera något, till exempel att lösa matematiska ekvationer, innan du behärska det? Nu har vi svaret: Det är åtta (8)!

Vi har genomfört en studie med data från kurser konstruerade med Open Learning Initiative-metoden (OLI). OLI-metoden ger bland annat ger konstruktiv återkoppling efter varje besvarad fråga. Till vår egen förvåning kom vi fram till till ett överraskande stabilt svar:  antalet nödvändiga möjligheter att träna måste vara åtta (detta kommer att täcka behoven hos 98 % av eleverna). Goda nyheter för alla som kämpar med tradiga läxor!

How much repetition is needed in order to master something?

When in school, have you ever wondered how many times you have to repeat something, such as solving mathematical equations, before you will master it? Now we have the answer: It is eight (8)!

We have performed a study on data from courses using the Open Learning Initiative (OLI) methodology.  Among other things, OLI courses give constructive feedback after each question. To our own surprise, we came to an astonishingly stable answer. The number of necessary opportunities to practice needs to be eight (this will cover the needs of 98% of the learners). Good news for all learners struggling with tedious homework!

Walking with Seminars – Finally!

After no less than twelve failed* attempts in two years to publish our study on walking seminars, we finally managed to identify a venue for our research: International Journal of Environmental Research and Public Health, which took less than six weeks, including a revision, from submission to publication! In the meantime, this study has caught attention from KTH internally and been used for external promotion. First in KTH Magazine, which lead to a video recording in Swedish and after that got 100.000 views they translated it to English. Apparently someone in Italy understands one of those languages. Now, KTH has published a promotion video to attract Masters students to KTH. In it, KTH gives ten reasons to study at KTH. Guess what reason number 6 is? Personally we think walking with us is a way better argument to study here than first claiming (#5) that “Sustainability is a … guiding star for KTH” and then advertising (#10) for taking a flight out of here.
