高校校园社交媒体平台功能需求的KANO模型分析——以“Pocket University”为例

社交媒体在高校学生生活中扮演重要角色, 在这一形势下, 围绕校园生活开发的高校校园社交媒体也逐渐在学生中得到应用。研究学生对于该类平台的功能需求, 对推动高校校园社交媒体平台的健康发展具有积极意义。本文以PU平台为例, 在参考有关社交媒体及其功能需求文献的基础上, 以KNAO模型为理论基础, 借助访谈、问卷调查对高校学生的PU平台各功能项的质量属性进行归纳, 根据各类质量属性分析其功能需求, 最后基于研究结论对平台改进提出相关建议。     

Understanding food processing and systems: Pilot testing a standards‐aligned middle school curriculum

Consumer confidence and trust, as it relates to the food system, is one of the most sensitive areas within consumers’ understanding of food. Surveys have shown that a large majority of people would like to learn more about agriculture and food manufacturing, with young people being among those most eager for more information about where their food comes from. Food‐focused educational resources often go unused due to teachers’ lack of familiarity with the subject area, the pressures of standardized testing, and lack of alignment to state content standards. Building on the success of the Hands On Classrooms platform that developed and validated curricula with high adoption rates by teachers and a demonstrated impact on student knowledge and self‐efficacy, a new curriculum on food system and food processing was developed and pilot tested. Two teachers from rural Virginia and Tennessee participated in the study. Both teachers received online professional development prior to implementation. Students were given pretests and posttests to measure (a) what impact does the curriculum have on students’ knowledge of food systems and processing and (b) to what extent does the curriculum have an impact on student's self‐reported skills related to these topics? A total of 87 students completed the assessments and showed significant improvements from pretest to posttest on both knowledge (p < .001) and skills (p < .001) related specifically to where food comes from and how it is processed, content that is typically not covered in middle school curriculum. Further research can be undertaken to measure the impact on others in different geographic and socioeconomic areas to provide additional data to validate the program.     

说古代菜肴的"汤"

菜肴中的汤类，不始于唐代，唐以前只有作调味的清汤，称为“汁”。唐代出现作保健饮料的“饮子”，从宋代起称为“汤”。到元代，“汤”才可以专称羹中的浓汤类，于是菜肴中有了汤，但尚未成为菜肴的一个门类。到清代，“汤”才发展为菜肴中一个大的门类，并且将羹也包括其中。     

中国饮食文化概论融合课程思政元素创新教学模式的实践与思考

中国饮食文化是中国传统文化的重要组成部分,蕴含着丰富的哲学思想,是高校学生思想政治教育的重要文化资源。新时期,高校学生被各种文化思潮与价值观念冲击着,开展思想政治教育工作就显得尤为重要。中国饮食文化概论融合课程思政元素是在中国饮食文化概论课程教学中,结合课程内容融合思政教育内容,创新教学模式。通过中国饮食文化和思想政治元素的有机结合,不断提高教学质量,提高学生个人修养,让学生成为德才兼备、全面发展的人才,切实把思想政治工作贯穿教育教学全过程。本文就中国饮食文化概论融合思政元素的必要性、可行性、实施途径及现实意义做了一些探索和思考。

‘Who likes fish? And I don’t mean fish fingers!’ Taste education,culinary capital,and distinction in a rural middle-class primary school

ABSTRACT

This paper explores how middle-class distinction is produced in a primary school by focusing on four different ‘scenes’. Using Bourdieu’s notion of distinction, this paper shows how children are educated on matters of middle-class taste. I argue that privilege is produced through food education in different formats. This taste education goes beyond what one should merely eat and consume. It is situated within a middle-class nostalgia for rural ‘villageness’. While this type of distinction is not in and of itself problematic, this paper discusses the implications for when these ideas are taken up in policy, and expected of all schools. I argue educators need to be aware of how these values are being rolled out as universal values, expected of schools in diverse areas. Educators should pay attention to how middle-class distinction and privilege is produced and reproduced in schools, in order to create a more inclusive food education.     

语言理解中语义与句法加工的脑功能定位研究

语义加工与句法加工的关系是当前语言理解领域的核心和热点问题,认知神经科学研究从大脑功能定位角度对之进行了探讨。采用脑功能成像技术对该问题的研究范式主要有三种:简单句与复杂句对比范式、语义违背与句法违背范式、语义控制与句法控制范式。虽然关于这两个加工过程的大脑功能定位取得了一些进展,但大量的研究结果之间并不一致,主要的争议在于句法和语义加工的差异到底涉及的是特异化的语言功能区还是工作记忆的差异、是否涉及内隐与外显加工的差异等问题。未来,语义和句法加工的大脑定位及相互关系仍需要进一步的深入研究。     

从指称关系看语用学和系统功能语言学互补的可能性

语用学和系统功能语言学是当今发展很快的两个重要语言学科,它们在各自的研究领域都取得了长足的发展。虽然语用学和系统功能语言学在许多方面有相似之处,但相互的影响却甚微。本文通过对指称关系在两个学科的研究比较,探讨语用学和系统功能语言学的有联系和互补性,从而为两个学科之间的联系提供理论上的依据.
