Spatial ability (SA) is the cognitive capacity to understand and mentally manipulate concepts of objects, remembering relationships among their parts and those of their surroundings. Spatial ability provides a learning advantage in science and may be useful in anatomy and technical skills in health care. This study aimed to assess the relationship between SA and anatomy scores in first- and second-year medical students. The training sessions focused on the analysis of the spatial component of objects' structure and their interaction as applied to medicine; SA was tested using the Visualization of Rotation (ROT) test. The intervention group (n = 29) received training and their pre- and post-training scores for the SA tests were compared to a control group (n = 75). Both groups improved their mean scores in the follow-up SA test (P < 0.010). There was no significant difference in SA scores between the groups for either SA test (P = 0.31, P = 0.90). The SA scores for female students were significantly lower than for male students, both at baseline and follow-up (P < 0.010). Anatomy training and assessment were administered by the anatomy department of the medical school, and examination scores were not significantly different between the two groups post-intervention (P = 0.33). However, participants with scores in the bottom quartile for SA performed worse in the anatomy questions (P < 0.001). Spatial awareness training did not improve SA or anatomy scores; however, SA may identify students who may benefit from additional academic support.  相似文献

2013年教育部开始着手制定《中国学生发展核心素养》,由此启动普通高中美术课程标准的修订,这也标志中国的教育已经进入了核心素养时代。美术鉴赏是高中美术课程中重要的内容,但实际教学效果却不尽人意。教与学是一方主导、一方被动的分离状态,表现为教师为教而教,学生为知识而学习。学生无暇顾及与高考无关的课程,往往浅表性、单向度地接受碎片化知识的输入,因而不能有效地对情境中的图像进行识读和判断。核心素养下的高中美术鉴赏需要唤醒教与学双方主体的课程意识,同时也对教师的专业素质提出了更高的要求。创新教学过程和学生的学习方法是实现学生核心素养形成的必经桥梁,是值得专家学者和广大一线教师不断地去探究、发掘的重要环节。  相似文献

ABSTRACT

Using cross-sectional data from 504 students from four Kenyan universities, this study evaluates the indirect effect of brand personality on the relationship between social media and students’ behavioral intentions to enroll in postgraduate studies. Additionally, the study examines the moderating effect of attitude on the relationship between social media and brand personality, social media and students’ behavioral intentions, brand personality and students’ behavioral intentions. Finally, it investigates the moderating effect of attitude on the indirect process of brand personality on the relationship between social media and students’ behavioral intentions. The study is guided by the Theory of Planned Behavior, Technology Acceptance Model and Self Congruity Theory. Process Macro is used to analyze data. Results indicate that social media significantly predicts students’ behavioral intentions and this relationship is partially mediated by brand personality. Besides, attitude moderates the relationship between social media and students’ behavioral intentions and also the relationship between brand personality and students’ behavioral intentions. Finally, attitude has a conditional effect on the indirect relationship between social media and student’s behavioral intentions via brand personality and this effect is much stronger with a higher level of attitude. These findings contribute new knowledge to literature and theory.  相似文献

改革开放以来,我国体育产业从无到有一路发展,在成为受国家重视的重要产业的今天,相比国际体育产业发达国家,我们仍然处于明显的劣势,即便是国内的中、高端体育消费市场也几乎被国外大品牌企业占据大半,更不用说我们的企业走出国门了。然而我们的体育产业依然有着潜在的核心竞争力,为了将这种竞争力变成现实的力量,我们必须积极营造成熟、规范的体育消费市场;积极发挥竞技体育发展水平的优势;积极与国际知名企业合作,实现互利共赢。  相似文献

Abstract

Institutional repositories (IRs) present platform to disseminate research findings to complement the traditional scholarly communication model. The use of IRs is beneficial to authors, host institutions, libraries and society at large. Despite the numerous benefits of IRs, there is low deposit of scholarly works by lecturers and the investment on IRs seems to be a waste. This study examined determinants of perceived ease of use (PEOU) of IRs by lecturers in Nigerian universities. A survey of lecturers received 857 respondents. Awareness, anchor and adjustment factors were found to be determinants of PEOU of Institutional repositories by lecturers in Nigerian Universities.  相似文献

The massive number of Internet of Things (IoT) devices connected to the Internet is continuously increasing. The operations of these devices rely on consuming huge amounts of energy. Power limitation is a major issue hindering the operation of IoT applications and services. To improve operational visibility, Low-power devices which constitute IoT networks, drive the need for sustainable sources of energy to carry out their tasks for a prolonged period of time. Moreover, the means to ensure energy sustainability and QoS must consider the stochastic nature of the energy supplies and dynamic IoT environments. Artificial Intelligence (AI) enhanced protocols and algorithms are capable of predicting and forecasting demand as well as providing leverage at different stages of energy use to supply. AI will improve the efficiency of energy infrastructure and decrease waste in distributed energy systems, ensuring their long-term viability. In this paper, we conduct a survey to explore enhanced AI-based solutions to achieve energy sustainability in IoT applications. AI is relevant through the integration of various Machine Learning (ML) and Swarm Intelligence (SI) techniques in the design of existing protocols. ML mechanisms used in the literature include variously supervised and unsupervised learning methods as well as reinforcement learning (RL) solutions. The survey constitutes a complete guideline for readers who wish to get acquainted with recent development and research advances in AI-based energy sustainability in IoT Networks. The survey also explores the different open issues and challenges.  相似文献
