耐热木聚糖酶源细菌筛选、鉴定及酶学性质

利用木聚糖作为唯一碳源的基础盐培养,在50℃培养条件下,从新乡周围土样及腐殖质中筛选到1株产耐热β-木聚糖酶细菌,初步鉴定为巨大芽孢杆菌（Bacillus megaterium FLH-2）.该菌株在40~55℃生长良好,最适生长温度50℃.木聚糖酶粗酶性质研究表明：该酶最适pH和最适温度分别为6.0和65℃;在pH 5.0~9.0及温度30~75℃之间酶活相对稳定,分别处理30 min,相对酶活仍保持在80%以上.     

高职教师学习共同体的构建

学习共同体是一种全新的合作学习方式,是一种自主、平等和互惠的合作共同体。教师学习共同体与学校是利益共同体,学校通过搭建教学共同体、科研共同体、技术攻关共同体等合作学习的组织平台,为教师合作提供良好的空间。学校可以在合作氛围创设、平台搭建、机制完善和资源保障上发挥作用,为教师之间的合作学习和专业成长创造更多的有利条件。     

Teaching ‘community engagement’ in engineering education for international development: Integration of an interdisciplinary social work curriculum

This article reviews the literature on challenges faced by engineering faculty in educating their students on community-engaged, sustainable technical solutions in developing countries. We review a number of approaches to increasing teaching modules on social and community components of international development education, from adding capstone courses and educational track seminars to integrating content from other disciplines, particularly the social sciences. After summarising recent pedagogical strategies to increase content on community-focused development, we present a case study of how one engineering programme incorporates social work students and faculty to infuse strategies for community engagement in designing and implementing student-led global engineering development projects. We outline how this interdisciplinary pedagogical approach teaches students from the two disciplines to work together in addressing power balances, economic and social issues and overall sustainability of international development projects.     

“Ah,I know why…”: children developing understandings through engaging with a picture book

This article describes part of a study that explored the responses of nine‐ and ten‐year‐old children during a picturebook read aloud in a small group setting in a New Zealand classroom. The read aloud was interactive, where the participants were encouraged to respond to the book and to each other throughout the session. The authors created a framework for analysing the responses, adapting the model of Lawrence Sipe (2008) with its five categories of literary understanding, by expanding on the analytical category to enable a finer analysis of the responses. This article discusses the children's depth of thinking and the understandings they developed as they engaged with the read aloud. It also describes how the adapted framework allowed a closer analysis of these understandings, including the way the elements of art used in the illustrations contributed to the children's ideas. The findings suggest ways picturebooks can be used to promote children's thinking and how teachers can guide discussion about a complex text. Implications for use of the framework in further research are discussed.     

What makes a cMOOC community endure? Multiple participant perspectives from diverse cMOOCs

Imagine the challenge of being immersed in a dynamic learning network where you play brinkmanship with being overwhelmed by a plethora of information, comments, and conversations on a topic of intense interest to you. Through adept facilitation, the comments and encouragement of fellow participants, and your own perseverance, you develop a network of personal connections which serve as metaphorical flying buttresses creating enough stability that you are able to learn in a new, yet profoundly meaningful way – the connectivist massive open online course (cMOOC) way. Through the lens of autoethnography, five seasoned educators collaboratively reflect on their motivation for participating in their initial cMOOC. They analyze their lived experience, what they found most engaging, and most importantly, they grapple with why cMOOC communities often endure past official end-dates. This article attempts to provide insight into the thrill and depth of learning and connection possible through participation in cMOOCs.

地方高校与社区教育互动发展研究——基于学习型社会建设的思考

在终身教育、终身学习理念的指导下,在服务区域社会功能的引领下,地方高校与社区教育应打破彼此间的壁垒,遵循双向沟通、共建共享、系统规范、社会服务等互动发展原则;构建资源共享、定向培养、专项服务、机构共建、协同创新等多元化互动发展模式;完善制度保障机制、评估激励机制等互动发展动态管理体系;有力地促进地方高校应用型人才的培养,社区教育的规范和快速发展,以及学习型社会的建设.     

影响教育虚拟社区中学习动机激发因素的实证分析

教育虚拟社区中的学习动机是学习者通过自我调节,使自身的内在要求与学习行为的外在诱因相协调,引起和维持学习者在教育虚拟社区中的学习活动,并激励、指引学习者的行为朝向一定学习目标的内部心理状态。在基于课程＂学习科学与技术＂的教育虚拟社区学习实践的基础上,实证分析了教育虚拟社区中学习动机激发的影响因素,通过描述性统计、回归分析、因子分析和聚类分析发现：教师因素、学习者因素、环境因素和文化因素是影响学习者在教育虚拟社区中学习动机激发的四大要素,学习者在教育虚拟社区中学习动机的激发有赖于以上各因素协同作用的发挥,由此提出了影响教育虚拟社区学习动机激发因素的分析模型。     

论高职院校的公共学习社区功能

高职院校建设公共学习社区是正向处理高校四大职能后的位移,在U型理论指导下建设区域协同创新中心是高职院校的制度安排。制度设计过程中,要关注三大力量,适应发展的新环境;要着眼于培育四大特性,应对发展的新要求;要着力于建设三大共同体,协同社区幸福美好发展。
