In this study, we analyzed students’ reasoning and explanations of friction concepts before and after engaging in guided experimentation with visuohaptic (VH) simulations. The VH experimentation included two affordances: visual cues and haptic feedback. Specifically, we analyzed the outcomes of two treatment groups with different sequences of affordance introduction. The first treatment group started with visual cues, with haptic feedback added later, while the second treatment group started with haptic feedback and added the visual cues later. We recruited 48 students who had previously taken at least one physics course. Participants completed a pre‐ and posttest assessment, which included both procedural and conceptual questions about friction before and after the guided experimentation task. The results show that the participants from both treatment groups benefited from using VH simulations. Both treatment groups showed statistically significant pre/post improvements in their understanding of friction. Moreover, both treatment groups showed a statistically significant increase in the conceptual understanding of friction concepts from pretest to posttest with moderate to strong effect sizes. Implications for laboratory instruction are also discussed.
In this study, we: (a) compared the differences in the learning of friction concepts between a physical manipulative tool (PMT) and a visuohaptic simulation (VHS) in four different configurations (visually enhanced feedback on/off, force feedback on/off), and (b) analyzed the influence of the visual and haptic feedback for learning the concept of friction. Specifically, this study explored the role of an object’s size in friction. In a three-stage experiment (i.e., pre-test, experimentation, and post-test), 206 undergraduate students compared the friction force, speed, acceleration, and traveled distance between two cubes with the same weight but different sizes pushed on a smooth surface. Our results suggest that (a) VHS was an effective tool for promoting the learning of friction concepts actively, (b) learners in the VHS condition outperformed the learners in the PMT condition (PMT < VHS), (c) the easy identification of the forces by enhanced visual cues promoted the acquisition of scientific knowledge, (d) the haptic feedback promoted a grounded experience for learning about friction, and (e) learners in the Sequenced (H→H + V) condition had more learning benefits than the Simultaneous (H + V), Visual, and Haptic conditions. Students in the Sequenced (H→H + V) condition took advantage of the affordances of the virtual and physical manipulatives. The implication for teaching and learning is that the virtual and physical affordances of the learning tools and the students’ prior knowledge must be considered in the design of the VHS to enhance learning. For the education research, the study implied that body actions positively impacted the learning experience.
The purpose of this study was to explore the process of designing a visuohaptic simulation for learning structural analysis following a learner-centered approach (LCD). Our implementation of an LCD approach followed a three-part iterative process: (1) requirements analysis and specification, (2) multimedia application design, and (3) prototype inspection. In designing the learning tasks, we employed a three-phase pedagogical approach of prediction, experimentation, and confirmation. We found that designing a visuohaptic si-
