The purpose of this study was to investigate the effectiveness of two different concept mapping methods - learner-generated and expert-generated concept mapping - in computer-based video learning. The students' attitudes toward the use of the concept mapping and computer-based instruction in general were also investigated. The study was performed using the entire enrollment of the junior level undergraduate course (n = 65) Developmental Psychology for Educators (EPSY-320) class, the spring semester of 2010 at Texas A&M University. Using experimental research design, the relationship between student achievements and learning tools was observed. The convenience sampling method was used to assign the students randomly to two treatment groups. The study built on previous research findings on the instructional use of video and concept mapping. It focused on the relative influence of expert-generated versus learner-generated concept maps on student achievement during computer-based video instruction.

Results indicated that there were no significant differences among achievements of students who used either learner-generated concept maps or expert-generated concept maps in the study. However, the expert-generated concept mapping group spent significantly less time than the learner-generated concept mapping group interacting with the instructional tool. The findings revealed that concept map scores mediated the relationships between the numbers of clicks on the video player control, time spent creating concept maps, and time spent on all interaction and student achievement. Although the variables - the number of clicks on the video player control, time spent creating concept maps, and time spent on all interactions - did not have a direct effect on student achievement, they affected the concept map scores, which in turn affected student achievement.

The three variables - perceived usefulness, ease of use, and attitude toward use - were used to define the attitude of the students toward the instructional tool. The results showed that the attitude of the expert-generated group toward the instructional tool was significantly higher than the learner-generated group. Also, on average, the expert-generated concept mapping group expressed neutral feelings on using the instructional tool to improve their learning performance. Alternatively, the learner-generated group did not appreciate the value of this tool. Both groups reported neutral views about the ease of use of the instructional tool.

In conclusion, concept mapping might enhance cognitive learning after the basic skills are acquired and the learners become competent concept mappers. During the creation of concept maps, cognitive load might hinder student learning; therefore, students must be well trained before starting to use the learning tool. Moreover, concept map scores might be used as student grades in video-based learning.
