| Abstract | The purpose of this study was to examine the “spatial contiguity effect” in computer-based nature science instruction, as well as investigated the possible effect(s) prior knowledge may have on student cognitive load and performance. We accounted for “spatial contiguity effect” in instruction to support student learning, and were interested in if an integrated presentation format could lighten the cognitive load a student needs to undergo in the learning process and facilitate understanding of information. The technique used for spatially integration was connecting lines between the different modes of information within the instruction. By using the lines, learners were expected to reduce cognitive load inducing search for diagrammatic referents in the text, and thus enhanced their learning. We also tried to understand if prior knowledge could mediate students’ cognitive load and learning performance. Of particular interest to this study was the spatial contiguity effect on learners with different qualities, in this study, especially different levels of prior knowledge. The results of the study showed that the performance of the students in the group with integrated presentation format group was significantly higher than that of students in the group with separated presentation format, but there was no significant difference between the two groups for cognitive load. The performance of the students with high-prior knowledge was significantly higher than that of students with low-prior knowledge, but there was no significant difference in cognitive load between the two groups. Finally, the spatial contiguity effect was larger on the learners with high-prior knowledge, compared to the low-prior ones. They had significant better performance in the integrated condition than in the separated condition. |
