Abstract

This study provides evidence on the impact of including warm messages in elaborated feedback. These messages are aimed at the motivational process that can be mobilised by feedback and that which can condition its reception and the way students face the task (post-feedback behaviour). In a task where secondary school students had to learn a new strategy for improving their reading skills in a computer-based environment, we compared the use of elaborated feedback with the use of elaborated feedback enhanced with motivational messages (warm elaborated feedback) and a control condition (without feedback). The results showed that students receiving warm elaborated feedback revisited the text more often than those receiving only the elaborated feedback, and that both groups revisited the text more than the control group. This finding suggests that controlling the motivational aspects in feedback messages may increase the effectiveness of elaborated feedback.  相似文献

The integration of information in a digital,multi-modal learning environment     

《Learning and Instruction》2019

The aim of the reported eye-tracking study was to investigate whether learners integrate information presented on several pages within a digital learning environment and whether the underlying processes differ between a purely text-based and a multi-modal digital learning environment. Participants (N = 97) learned about the development of tornados. Picture presentation (yes vs. no) and presentation of inconsistent information between pages (yes vs. no) was varied between-subjects. Results showed that inconsistent information led to more intense gaze behavior. This indicates that learners re-activated information presented on previous pages to integrate it with the actual information, enabling them to detect the inconsistencies. Furthermore, the data pattern for text-related gaze behavior was not influenced by picture presentation, indicating that cognitive processes in purely text based or multi-modal learning environments are much the same. Comprehension outcomes did not differ between groups. The implications of these results are discussed.  相似文献   

Integrating a moral reasoning game in a blended learning setting: effects on students' interest and performance     

Jon-Chao Hong  Nien-Chen Wu  Ying-Luan Huang  Pei-Hsin Lin  Yi-Ling Chen 《Interactive Learning Environments》2016,24(3):572-589

A new approach to moral education using blended learning has been developed. This approach involves 10 scenarios that are designed as a web-based game and serves as a basis for group moral-consequence-based reasoning, which is developed based on a hypothetical-deductive model. The aim of the study was to examine the changes in students' blended learning interest and reasoning ability in a time series experimental design. After playing the game with the 10 initial scenarios during the first week of the study, participants were subjected to five blended learning sessions that required them to discuss the consequences of one of the 10 scenarios using hypothetical-deductive reasoning. After six weeks, the data from the 110 participants were analyzed using time series statistics. The results indicated that players were highly interested in the game, although their interest had a tendency to decrease slightly over time. Repetitive game play (i.e. practice) was positively associated with the players' moral reasoning performance. The study results may lend support to the design of a game with additional or more highly complex content for players to further develop students' consequential reasoning ability.  相似文献

Smart structures and materials     

V. K. Wadhawan 《Resonance》2005,10(11):27-41

A structure is an assembly that serves an engineering function. It is reasonable to expect that all engineering design should be smart, and not dumb. But one can still make a distinction between smartly designed structures and smart structures. The latter term has acquired a specific technical meaning over the last few decades. A smart structure is that which has the ability to respond adaptively in a pre-designed useful and efficient manner to changes in environmental conditions, including any changes in its own condition; the response is adaptive in the sense that two or more stimuli or inputs may be received as anticipated and yet there is a single response function as per design. Smartness ensures that the structure gives optimum performance under a variety of environmental conditions. While structures with some degree of smartness have been designed from times immemorial, the current activity and excitement in this field derives its impetus from the level of sophistication achieved in materials science, information technology, measurement science, sensors, actuators, signal processing, nanotechnology, cybernetics, artificial intelligence, and biomimetics.  相似文献

Navigation system for a smart wheelchair     

BONCIAndrea LONGHISauro MONTERIUAndrea VACCARINIMassimo 《浙江大学学报(A卷英文版)》2005,6(2):110-117

Recent results on the development of a navigation system for a smart wheelchair are presented in this paper. In order to reduce the development cost, a modular solution is designed by using commercial and low cost devices. The functionalities of the tracking control system are described. Experimental results of the proposed assistive system are also presented and discussed.  相似文献
