“…PBL started in medical education, suffused professional education, and has seeped into K-12 schools, with potential to achieve new science standards in states and countries (BouJaoude, 2012;NGSS Lead States, 2013;McConnell et al, 2018). Research suggests that PBL has many benefits, including improvements in problem-solving skills (Hmelo-Silver, 2004); cognitive engagement (Rotgans & Schmidt, 2011); academic learning, retention, and skill development (Jensen, 2015); critical thinking (Iwaoka et al, 2010); creativity (Ozdemir & Dikici, 2017); communication (Koh et al, 2008); self-directed learning (Koh et al, 2008;Loyens et al, 2008); biology research skills (Berry, 2017); working with others/teamwork skills (Koh et al, 2008;Brown et al, 2013); coping with uncertainty (Koh et al, 2008); and multicultural groups working together (Brown et al, 2013). Different instructor roles can present implementation challenges (Abdelkhalek et al, 2010), which can be reduced by education about the approach (Dole et al, 2016).…”
