高师《现代教育技术》教材改革的实践与思考

教材改革前的《现代教育技术》存在内容陈旧、庞杂等问题,难以满足学生就业、成才的需求.改革后的《现代教育技术》受到师生欢迎,但仍需重视教学设计理论和方法,注意对理论部分内容选择和组织的突破,应维持对本课程内容与其他相关课程内容的平衡等.     

Collaborative project-based learning: an integrative science and technological education project

Background: Blending collaborative learning and project-based learning (PBL) based on Wolff (2003) design categories, students interacted in a learning environment where they developed their technology integration practices as well as their technological and collaborative skills.

Purpose: The study aims to understand how seventh grade students perceive a collaborative web-based science project in light of Wolff’s design categories. The goal of the project is to develop their technological and collaborative skills, to educate them about technology integration practices, and to provide an optimum collaborative, PBL experience.

Sample: Seventh grade students aged 12–14 (n = 15) were selected from a rural K–12 school in Turkey through purposeful sampling.

Design and methods: The current study applied proactive action research since it focused on utilizing a new way to enhance students’ technological and collaborative skills and to demonstrate technology integration into science coursework. Data were collected qualitatively through interviews, observation forms, forum archives, and website evaluation rubrics.

Results: The results found virtual spaces such as online tutorials, forums, and collaborative and communicative tools to be beneficial for collaborative PBL. The study supported Wolff’s design features for a collaborative PBL environment, applying features appropriate for a rural K–12 school setting and creating a digitally-enriched environment. As the forum could not be used as effectively as expected because of school limitations, more flexible spaces independent of time and space were needed.

Conclusions: This study’s interdisciplinary, collaborative PBL was efficient in enhancing students’ advanced technological and collaborative skills, as well as exposing them to practices for integrating technology into science. The study applied design features for a collaborative PBL environment with certain revisions.

“中体西用”与中国教育近代化

鸦片战争以后,中国在政治、军事、经济和文化教育等各个领域都面临着深刻的危机,西方思想文化与中国传统文化发生了激烈的交锋。在近代中国文化教育转型过程中,"中体西用"对于改变传统教育的空疏之风,打破八股取士制度的禁锢具有划时代意义。     

环境规制对企业绿色技术创新的影响研究及政策启示

随着工业化经济的快速发展,环境问题成为人们关注的焦点,环境规制及导致经济方式发生根本改变的绿色技术创新成为研究热点.本文通过理论模型分析排污税、排污许可证、统一的排放标准三种环境规制政策与企业采纳绿色技术程度之间的关系发现,当传统技术和绿色减排技术的边际减排成本(MAC)曲线存在交点时,三种规制政策对企业绿色技术创新与扩散的影响模式相同;企业采纳绿色技术的程度与环境规制政策强度呈现“倒U型”关系.若考虑企业的边际减排成本等异质性,则企业采纳绿色技术的程度与环境规制政策之间的关系会呈现更为复杂的非单调关系,可能存在“倒W型”.合理的环境规制政策配合适度的严厉性可以激励绿色技术创新,有利于实现经济发展和环境保护的双赢.     

医药企业知识基础、合作能力与技术并购创新绩效

以2007-2018年我国沪深A股生物医药行业发生的109起技术并购事件为研究样本,构建含有中介变量的回归模型,在实证检验并购方技术特征与创新绩效关系的基础上,探究了吸收能力的中介效应。研究表明：企业知识基础和合作能力对创新绩效有显著正向影响;吸收能力在知识基础、合作能力与创新绩效关系中均起到部分中介作用。进一步研究发现,并购方CEO接受技术类教育水平越高,企业技术特征的敏感度更高;互补型技术并购加强了主体知识基础对创新绩效的正向影响,相似性技术并购则加强了合作能力对创新绩效的正向影响。     

Comparison of crowdsourcing platforms from social-psychological and motivational perspectives

The increasing need to compete in innovation and the prevalence of IT in social and economic interactions have led to greater globalization in innovation sourcing, particularly through online crowdsourcing platforms. Crowdsourcing platform participation, a phenomenon inadequately covered, is an instance of providing an innovative solution or idea intertwined with personal and social factors that interact to result in a behavior. A better understanding of the impact of social factors and participants’ hedonic, utilitarian, and social motivations can guide the design and management of these crowdsourcing platforms to foster sustained engagement. This study considered the competitive and social nature of these platforms and analyzed participation intentions from a novel standpoint—a combination of motivational and socio-cognitive perspectives and their relationships within two different types of crowdsourcing platforms: Atizo’s third-party-hosted community and Nokia’s brand-hosted IdeasProject community. A comparison of these two types of crowdsourcing platforms for the same activity of ideation at an individual level revealed differences in behavior determinants based on the platform host type, domain specificity, and mechanisms supporting different motives and social factors.
