This study reports the effects of using word clouds to support students' knowledge integration from online inquiry as demonstrated by blog posts, tags and concept maps. Fifty-four undergraduate students from a medium-sized university in the northwestern United States were randomly assigned into two groups and blogged for five weeks. To support students' online searching activity, the treatment group was provided a list of concepts in the format of a word cloud. The control group received the same list of concepts in an alphabetic order. Data analyses included comparing participant-attached tags and individual concept maps to the instructor's keyword list. Results revealed that the word clouds facilitated the construction of schema in a top-down deductive approach, which could be a meaningful and efficient way of learning.
