学生参与式体育课堂评价对大学生体育学习动机和学习效果的影响

为了检验学生参与式体育课堂评价对大学生体育学习动机和学习效果的影响效应。研究以132名大学生为实验对象,通过传统体育课堂评价方式和学生参与式体育课堂评价方式进行为期16周的教学实验。研究结果表明,学生参与式体育课堂评价:①对大学生体育学习动机的内部动机(t=-3.14,p=0.02)和自我调节能力(t=-5.03,p=0.01)具有显著促进效应;②对大学生体育学习基本心理需要的自主(t=-4.79,p=0.02)、能力(t=-8.77,p=0.01)和归属(t=-4.68,p=0.03)均具有显著影响效应;③可以有效提高学生体育学习的学习参与及运动技能水平。因此,学生参与式体育课堂评价对提高大学生体育学习动机和学习效果具有重要作用。

对广州市独立学院学生健美操学习兴趣的探讨

近几年来,健真撩项目已经是高校体育教学中的重要教学内容之一。善至已被很多高校列入必修教学大纲。健美操是以健、力、翼技能奏的一项新兴体育运动项日,并渌受高杖广大学生的青睐。笔者通过在教学实践中如何对独立学院学生健美撩学习兴趣的培养,不研提高学生的锻炼热情戚和快乐戚,以这到健身娱乐,形成终身体育意识的教学目的。本文是针对独立学院学生健真揉学习兴趣的调查分析,同时提出如何提高独立学院学生健兵操学习兴趣的方案,以及将教学方珐进行分析研究。旨在为健兵撩在独立学晓中的教学与开展提供参考。     

自主学习:科技期刊编辑再教育的一种有效途径

作者根据自己自主学习的体会,认为:作为科技信息的传播者,科技期刊编辑应该与时俱进,树立终身学习的意识,不断更新现有的知识结构,不断提高编辑素养,牢牢把握科技的前沿,才能更好地为读者和作者服务。     

基于表示学习的双层知识网络链路预测

当前,针对知识网络的链路预测主要是基于网络拓扑结构的相似性,很少考虑作者的研究领域,导致信息利用不充分等问题,因此本文提出了双层知识网络的链路预测框架hypernet2vec。双层知识网络,即作者合著关系网络和学术领域关系网络,利用网络表示学习,分别将两层网络中的节点映射到低维的向量空间,再输入到专门设计的卷积神经网络中计算并进行链路预测。与经典的链路预测指标如RA指标、LP指标和LRW指标等相比,hypernet2vec模型预测的AUC (area under curve)值取得了显著的提升,平均提升幅度达11.17%。文章还从情报产生层面和复杂系统层面,对模型发生作用的深层机理进行了探讨。     

Increasing student engagement using an Amazing Race–style competition

Background:Game-based learning is a successful strategy for teaching various concepts to students, from general orientations to more in-depth material. Pharmacy students in a first-year lab course were introduced to library and drug information resources through a lecture-style class in their first week of school, which was ineffective in terms of engagement. To combat this issue, the pharmacy liaison librarian advocated for moving this class session later in the semester and proposed a game-based activity to replace the lecture.Case Presentation:“The Amazing Race: Drug Information Edition” was inspired by a well-known TV competition that involves completing several stages (called “legs”) of challenges to finish the race. The librarian developed questions designed to make students use various parts of the library website as well as two drug information databases. Students competed in teams, and the first three teams to complete the race were awarded small prizes. The race was first implemented in 2018, and modifications were made to the 2019 iteration based on student feedback.Conclusions:Despite several challenges, the race was well received by both the students and the course instructors and increased engagement with introductory library and drug information material. The activity has enhanced the librarian''s relationship and collaboration with the course faculty and made a positive impression on the students.     

Redesigning library orientation for first-year medical students during the pandemic

Background:Prior to 2020, library orientation for first-year medical students at Weill Cornell Medicine took the form of an on-site treasure hunt competition. Due to the COVID-19 pandemic, the orientation for the MD class of 2024 was shifted to an all-virtual format. This shift mandated a full redesign of the library orientation.Case Presentation:The Samuel J. Wood Library sought to preserve the excitement and fun of the treasure hunt in the new virtual format. The competition was redesigned as a Zoom meeting using breakout rooms, with library faculty and staff serving as team facilitators. Tasks were rewritten, shifting the focus from the library''s physical spaces to its virtual services and online resources. The redesigned orientation was evaluated using two data sources: a postsession survey of student participants and a debriefing of the library employees who participated. Student evaluations were positive, while the faculty and staff provided numerous suggestions for improving future virtual orientations.Conclusions:A successful virtual library orientation requires careful preparation, including testing the competition tasks, full rehearsal with library facilitators, and a thoughtful approach to technology and logistics. We have chosen to share the materials we developed for other academic health sciences libraries that may wish to take a similar approach to their own virtual orientations.
