This contribution presents the literature research of two topics for the author's thesis. The first topic is long-term retention of academic knowledge that students learn at school which is a necessity for their future life and work.
We use the same knowledge-memory-source classification as Conway et al., 1997 and use the same retention of knowledge factors that Semb and Ellis, 1994 have described. The second topic of research is the effect of experiments in physics and inquiry-based physics education on students, which shows to be very positive.
A shift towards inquiry-based education is a European trend that we wish to find the long-term effects of.
