Abstract:
The purposes of this research was to study the effects of case-based learning on web using questioning techniques and reflective thinking upon critical thinking of undergraduate students. This study used an experiment research design and a factorial design 2x2. Treatment variables were : 1) two types of questioning techniques: Socratic question technique and 5W1H question technique and 2) two types reflective thinking methods: Digital storytelling and Essay. The samples were 83 undergraduate students and were divided into four groups. The research instruments were : 1) Lesson plans, 2) Case-Based Learning on web using question techniques and reflective thinking, 3) Cornell Critical Thinking Test level Z, and 4) Analysis model for analyzing depth of critical thinking (Yang, 2008). Data were analyzed using content analysis, mean ( ), standard deviation (S.D.), One-way ANOVA and Two-way ANOVA. The research findings were: 1. The students studied with case-based learning on web using different questioning techniques had no difference on critical thinking score at the .05 level of significance. 2. The students studied with case-based learning on web using different reflective thinking methods had difference on critical thinking score at the .05 level of significance. 3. The students studied with case-based learning on web using different questioning techniques and reflective thinking methods had higher critical thinking score in all three assessments.
