Linear models: Fuller (1969, 1970); Dreyfus & Dreyfus (1986); Berliner (1994, 2001); Steffy & Wolfe (2001)
Parabolic models: Burke, Christensen, Fessler & Price (1987); Lynn (2002); Day (2008); Gonçalves (2009)
THEORIES OF PROFESSIONEL DEVELOPMENT
![Page 4: WIM VAN DE GRIFT MICHELLE HELMS-LORENZ University of Groningen The Netherlands](https://reader035.vdocuments.net/reader035/viewer/2022062814/56816867550346895ddec980/html5/thumbnails/4.jpg)
PRIOR EMPIRICAL STUDIESHargreaves (2005); Holloway (2003); Huberman (1989); Rosenholtz & Simpson (1990); Van de Grift, Van der Wal & Torenbeek (2011) found indications that teachers with 20-30 years of teaching experience with lower teaching abilities than teachers with less and with more teaching experience
![Page 5: WIM VAN DE GRIFT MICHELLE HELMS-LORENZ University of Groningen The Netherlands](https://reader035.vdocuments.net/reader035/viewer/2022062814/56816867550346895ddec980/html5/thumbnails/5.jpg)
Lineair or parabolic development?• Do teachers have higher teaching qualities
with more years of experience or,• do they show a dip in teaching abilities
between 20-30 years of experience?

1. 80-85% of the teachers with 20-30 years of experience seem to have a serious dip in their teaching abilities
2. Further, longitudinal research is needed to find an explanation (mid life crisis?; bad teacher training procedures 25 years ago?)
