“…Namely, common survey measures have increasingly come under criticism (Clarebout, Elen, Luyten, & Bamps, 2001;Hofer & Pintrich, 1997;Maggioni, Riconscente, & Alexander 2006) and the findings of studies in terms of development can be confounding. For instance, despite modeling similar trajectories, some studies find a fair percentage of middle school participants (e.g., Krettenauer, 2005;Mason & Scirica, 2006) and younger (Kuhn et al, 2000) are at the uppermost levels of development, while in other studies graduate (e.g., Dale, 2005) and doctorial (e.g., Friedman, 2004) students do not perform beyond intermediary levels.…”
