The mixed methods were employed in this study, which includes randomized-groups design experiment and content analysis. Two types of collective reflection learning tools which were simulated the Facebook and Skype platforms as the experimental groups, while guided self-reflection as the control group. “Milk and Health” was selected as the controversial issue for reflective judgment learning. One hundred and twenty-one nutrition-majored college juniors participated in this study. The results showed that: (1) all the employed online reflection strategies could enhance the reflective judgment performance of the nutrition-majored college juniors, and learners participated in the collective reflection groups presented better outcomes of their perceived learning; (2) learners’ with higher level of prior knowledge presented higher scores on reflective judgement performance; (3) learners’ reflective judgement performance was associated with the level of individual’s critical thinking tendency. Specifically, the ability of systemetic approaches significantly helped explain the learners’ reflective judgement performance and reflection self-learning. However, knowledge curiosity showed a negative correlation to reflective judgement performance; (4) the online collective reflective judgment strategy helped to modify conformity tendency, whereas the learners using Facebook-like platform decreased the general conformity tendency; (5) feedbacks from the participants indicated that online collective reflective judgement strategy is helpful for multifaceted thinking, interpreting information and data, research, learning motivation, providing various learning methods, and applying the concept of reflective judgement to daily life.反思判斷集合反思先備知識批判思考意向從眾效應傾向reflective judgmentcollective reflectionprior knowledgecritical thinking tendencyconformity tendency
