Participants were 52 undergraduate students who took a course about nature sciences. The instruction of this course was designed based on knowledge building pedagogy, using Knowledge Forum as a tool for students to construct their theories about scientific phenomena through online collaboration.\nData sources included: （1） a pre-post open-ended questionnaire that investigated students’ understanding of the nature of scientific theories; （2） the content of an online forum in which students posted their ideas; （3） students’ activities in the forum, for instance, number of students’ notes contributed, or number of notes built-on to each other’s notes. Data were analyzed through both qualitative and quantitative methods. From a qualitative perspective, we used content analysis to evaluate the quality of students’ discussion; from a quantitative perspectivea, paired t-test and chi-square were used to examine students’ change of views regarding the nature of scientific theories after the course.\nThe results showed that after a semester, students were able to develop a more constructivist-oriented view toward the nature of scientific theories. Their view shifted from a more positivist-oriented perspective to a more constructivist-oriented one. Further, the finding showed that there was significant improvement in students’ scientific inquiry as reflected in the progressively more sophisticated levels of the scientific concepts discussed online. Moreover, it was found that there was a statistically significant, positive correlation between students’ enhanced understanding of the nature of scientific theory and the intensity of students’ online activities. Additionally, the results also indicated that there was a significant, positive correlation between the depth of students’ scientific inquiry ( as reflected in the concepts inquired and discussed online) and the extent of students’ online activities. Some further suggestions and implications were also discussed in the study. |
