AbstractResearch on collaborative learning has revealed that peer-collaboration explanation activities facilitate reflection and metacognition and that establishing common ground and successful coordination are keys to realizing effective knowledge-sharing in collaborative learning tasks. Studies on computer-supported collaborative learning have investigated how awareness tools can facilitate coordination within a group and how the use of external facilitation scripts can elicit elaborated knowledge during collaboration. However, the separate and joint effects of these tools on the nature of the collaborative process and performance have rarely been investigated. This study investigates how two facilitation methods—coordination support via learner gaze-awareness feedback and metacognitive suggestion provision via a pedagogical conversational agent (PCA)—are able to enhance the learning process and learning gains. Eighty participants, organized into dyads, were enrolled in a 2 × 2 between-subject study. The first and second factors were the presence of real-time gaze feedback (no vs. visible gaze) and that of a suggestion-providing PCA (no vs. visible agent), respectively. Two evaluation methods were used: namely, dialog analysis of the collaborative process and evaluation of learning gains. The real-time gaze feedback and PCA suggestions facilitated the coordination process, while gaze was relatively more effective in improving the learning gains. Learners in the Gaze-feedback condition achieved superior learning gains upon receiving PCA suggestions. A successful coordination/high learning performance correlation was noted solely for learners receiving visible gaze feedback and PCA suggestions simultaneously (visible gaze/visible agent). This finding has the potential to yield improved collaborative processes and learning gains through integration of these two methods as well as contributing towards design principles for collaborative-learning support systems more generally.

And Performance

Computer-supported collaborative learning (CSCL) has received increasing research attention owing to advances in e-learning technology and paradigmatic shifts in the educational arena. Owing to the growing diversity in student population in terms of nationality, the role of cultural diversity becomes greatly pronounced, and must be addressed. In this study, a laboratory experiment with a 2×2×2 factorial design was conducted, to investigate the interaction effects of perceived cultural diversity, group size, and leadership, on learners’ performance and satisfaction with process. Contrary to an expected negative relationship between perceived cultural diversity and performance, a positive relationship emerged as a result of leadership. Leadership lowered learners’ satisfaction with the process in perceived homogeneous groups (as compared to perceived heterogeneous groups) and smaller groups (as compared to larger groups).

And Performance

In consideration of the rod, the tube, and the liquid column, a 3D dynamic model was established, which could be expressed as a set of partial differential equations. A measured torque curve and a calculated torque curve of Nan1-2-22 oil-well in Daqing oilfield were contrasted with each other which improved the rationality of this model. At last, we researched the influence of the stroke and the frequency of stroke on the displacement of rod, suspension velocity, suspension acceleration, polish rod load, and net torque of gearbox. This 3D dynamic model has a higher calculated accuracy and veracity and could be used to design and optimize the structure of rod pumping and the working process of pumping wells.

Abstract An adaptive method for suppressing mechanical vibration of multiple frequencies is investigated. The adaptive controller is reinforced with saturation alleviator to improve the convergence rate and performance of the adaptive algorithm. Tracking filters are used to extract harmonics of fluctuating frequencies and the anti-saturation unit works in series with the tracking filters to give constrained harmonic output. As a result, the controller is insensitive to abnormally large input that would otherwise induce saturation in actuators. A dynamic model is built for vibration suppression simulation and the numerical results indicate that the adaptive algorithm is effective in cases of multiple fluctuating frequencies and output saturation. Experiments were also conducted to test the performance of the adaptive method. Excitation with oscillating frequencies was applied, and the results have demonstrated that the harmonics can be suppressed effectively with the adaptive method.
