Effects of Node-Link Mapping on Non-Science Majors' Meaningful Learning and Conceptual Change in a Life-Science Survey Lecture Course

The purpose of this study was to assess the effects of node-link mapping on students' meaningful learning and conceptual change in a 1-semester introductory life-science course. This study used node-link mapping to integrate and apply the National Research Council's (NRC, 2005) three principles of human learning: engaging students' prior knowledge, fostering their metacognition, and supporting their formulation of a scientific conceptual framework. The study was a quasi-experimental, pretest-posttest, control group design. The sample consisted of 68 primarily freshmen non-science majors enrolled in two intact sections of the targeted course. Both groups received the same teacher-centered instruction and student-centered activities designed to promote meaningful learning and conceptual change; however, the activity format differed. Control group activities were written; treatment group activities were node-link mapped. Prior to instruction, both groups demonstrated equivalent knowledge and misconceptions associated with genetics and evolution (GE), and ecology and environmental science (EE). Mean differences, pre-to-post instruction, on the GE and EE meaningful learning exam scores and the EE conceptual change inventory scores between the writing group (control) and the node-link mapping group (treatment) were analyzed using repeated measures MANOVAs. There were no significant mean pre-to-post differences between groups with respect to meaningful learning in the GE or EE units, or conceptual change in the EE unit. However, independent of group membership, the overall mean pre-to-post increases in meaningful learning and conceptual change were significant. These findings suggest that both node-link mapping and writing, when used in conjunction with the National Research Council's (NRC, 2005) three principles of human learning, can promote meaningful learning and conceptual change. The only significant interaction found with respect to meaningful learning, conceptual change, and learning styles (Kolb, 2005) was a positive effect of node-link mapping on converger's meaningful learning. However, that result was probably an artifact of small sample size rather than a true treatment effect. No other significant interactions were found. These results suggest that all students, regardless of their learning style, can benefit from either node-link mapping or writing to promote meaningful learning and conceptual change in general life-science courses.
