Mobile APP for motivation to learning: an engineering case     

Min Jou  Yen-Ting Lin  Hsieh-Chih Tsai 《Interactive Learning Environments》2016,24(8):2048-2057

Synthesis of Materials is regarded as an important core subject in engineering education. However, many concepts and knowledge in the material synthesis can be rather abstract and difficult to understand by the student learners. Experiments are limited in scope due to lack of equipment, control of toxic materials, and risks of chemical reactions, which often restricts student imagination and student involvement in practical training. These reasons often led to poor learning attitude and learning performance among the students. Rapid developments in Cloud technology and mobile devices have provided new opportunities for developing novel learning tools for material synthesis. This study aims to introduce interest factors as a strategy for promoting learning interest and practical skills among the students. Chemical symbols, experimental themes, texts, and interactive elements were utilized to develop a theme-based Mobile Learning APP for teaching the practical techniques of material synthesis. The Mobile Learning APP was then integrated into a problem-based learning activity. A quasi-experimental design was used to investigate the resulting learning effectiveness from using the developed Mobile Learning APP. Results show that the Mobile Learning APP provided a significant positive effect on learning performance and that most students showed favorable attitudes toward the usage of the mobile learning system.  相似文献

Exploring anatomy and physiology using iPad applications          下载免费PDF全文

Tandra R. Chakraborty  Deborah F. Cooperstein 《Anatomical sciences education》2018,11(4):336-345

This study examined the use of iPads with anatomy applications (apps) in the laboratory sections of the largest undergraduate course at the university, Anatomy and Physiology, serving more than 300 students. The majority of these students were nursing, exercise science/physical education and biology majors. With a student survey (student opinion) and student practicum grades as metrics, this study determined whether the introduction of this novel mobile technology improved student grades and aided the students in learning the course material. The results indicated that students’ grades improved with the introduction of the iPads, and 78% of the students reported that the iPads facilitated their ability to learn the course material. There was a positive association between frequency of app use and standardized mastery of the course material, as students who used the apps more frequently scored higher and indicated that they felt as though they had learned the material more comprehensively. Owning or having an iPad at home did not have a significant effect on the learning of the material. The general consensus by students was that iPad anatomy apps should be used frequently to better develop student understanding of the course material.

高校数字媒体艺术专业动画教学创新与实践--以“乐高定格动画创意媒介实验课程”为例     

张一品 《数字教育》2020,(2):76-80

近年来,高校数字媒体艺术专业大量开设,专业的建设亟须教学实践跟进。数字媒体艺术内容与形式并重,与动画有着千丝万缕的联系,特别是,相当一部分动画专业转型数字媒体艺术专业,基础课程教学要根据专业方向及时调整。基于这一现实,本文以动画基础教学为例,探讨数字媒体艺术语境下动画类课程的改革,并通过相应的课程实践,验证了保留动画创作相关课程优良教学基础的重要性,以及不断发展和扩充其教学内容和手段的必要性。数字媒体艺术专业课程建设要保持开放的态度和开阔的行业视野,让课堂与高速发展的技术和传播环境紧密接轨。  相似文献

支持向量分类算法在5-HT3受体拮抗剂的构效关系研究中的应用     

杨善升  陆文聪  纪晓波  陈念贻 《上海大学学报(英文版)》2006,10(4):366-370

In this work, support vector classification （SVC） algorithm was used to build structure-activity relationship （SAR） model of the 5-hydroxytryptamine type 3 （5-HT3 ） receptor antagonists with 26 compounds. In a benchmark test, SVC was compared with several techniques of machine learning currently used in the field. The prediction performance of the model was discussed on the basis of the leave-one-out cross-validation. The results show that the accuracy of prediction of SVC model was higher than those of back propagation artificial neural network （BP ANN）, K-nearest neighbor （KNN） and Fisher methods.  相似文献
