The heart of educational data infrastructures = Conscious humanity and scientific responsibility,not infinite data and limitless experimentation

Education and education research are experiencing increased digitization and datafication, partly thanks to the rise in popularity of massively open online courses (MOOCs). The infrastructures that collect, store and analyse the resulting big data have received critical scrutiny from sociological, epistemological, ethical and analytical perspectives. These critiques tend to highlight concerns and/or warnings about the lack of the infrastructures' and builders' understanding of various nontechnical aspects of big data research (eg seeing data as neutral rather than as products of social processes). These critiques have primarily come from outside of the builder community, rendering the conversation largely one-sided and devoid of the voices of the builders themselves. The purpose of this paper is to re-balance the conversation by reporting the results of interviews with 11 data infrastructure builders in higher education institutions. The interviews reveal that builders engage deeply with the issues the critiques outline, not only thinking about them, but also developing practices to address them. The paper focuses the findings on three themes: designing a productive science, navigating ubiquitous ethics and achieving real human impact. Researchers, policymakers and infrastructure builders can use these accounts to better understand the building process and experience.     

Autoethnography of tutoring in the Russian university: from theoretical knowledge to practical implementation

Unlike traditional teachers, tutors now are much less able to confine their practice to the classroom setting. Herein, we address the challenges of actual tutoring practice at one Master’s degree program comprising offline and online learning activities along with student work placements. Building on the autoethnography and narrative analysis we highlight core themes structuring tutoring experience. We examined the challenges we met. We offer suggestions for tutors supporting students in a blended learning environment, and we argue acknowledgment of different roles and strategies applied by tutors across learning contexts make them more productive and less vulnerable towards conflicting messages of other actors involved in instructional communication.     

The Phenomenon of False Assumption in Historical and Educational Texts

This article describes two heuristic strategies for problem solving: the use of false assumption strategy and the use of double false assumption strategy. Both of these strategies have their roots deep in history. In this article, we define these two strategies and illustrate their use in a problem developed by Frances Pellos. The article provides an overview of occurrences of these two strategies in various mathematical and educational texts. The texts show clearly that both of these strategies played a significant role in mathematics education in the past. We present some examples from concrete historical documents, which we use later for the preparation of a teaching experiment. We also present the conclusions of an experiment conducted on three lower secondary schools in the Czech Republic, the goal of which was to test the applicability of the use of false assumption strategy as a propaedeutic to solving word problems using equations.     

What Kind of Contemporary Chinese Literature do Western Readers “Fancy”？

Interview with Cultural Celebrity on China Economic Net invited three experts in translation to discus how contemporary Chinese literature could “go global”. The three experts, who also participated in the 2014 Contemporary Chinese Literature Translation and Introduction Program, are： Ms. Lv Hong, Editor-in-Chief of Redwoods Magazine;Prof. Martin Woesler, Projessor at Munich University of Applied Languages, Mr. Sang Yichuan, President of Canada Maple Press.     

Kinematic differences between successful and faulty spikes in young volleyball players

ABSTRACT

This study was designated to investigate the kinematical differences between successful and faulty spikes, in order to identify the best strategies leading to better spike performance. Simulating a real-game condition, 13 elite youth attackers performed 6 spikes in the presence of 2 blocks. The kinematic variables of the spike performances were recorded using 6 optoelectronic cameras (Vicon Motion systems, Oxford, UK). The paired sample t-test was used to compare the kinematic variables recorded during the delivery of successful and faulty spikes. Among the successful trials, both the angular velocities of the knees (≈12.4%) and hips (≈13.3%), and the vertical velocity of the centre of mass at take-off (≈6.5%) and arm swing (≈8.2%) were considerably higher during the plant phase. Consequently, the jump (≈4.3%) and spike (≈1.5%) heights, as well as the wrist velocity (≈5.5%), were significantly higher during the jump phase of successful spikes. In successful spike performances, the attackers adopted higher hip and knee angular velocities, combined with efficient arm swings, to produce higher take-off velocities and reach higher jump heights. This approach provides them with the better position regarding the ball and the blockers to find the best path and hit the ball with higher arm velocities.

长株潭区域经济一体化发展的现状、问题与出路

自从1997年长株潭区域经济一体化被重新提到湖南经济发展的议事日程上以来,三市一体化进程明显加快。但是,由于体制上存在政府主导产生的诸多障碍,认识上有分歧,长株潭一体化进展不尽如人意。长株潭一体化未来的发展要积极转变体制和机制,以市场一体化为核心,以服务一体化为政府工作内容,建立职能管理的一体化,以适应市场经济的要求,推动湖南经济的更快发展。     

Teacher Professional Development Through a Collaborative Curriculum Project – an Example of TPACK in Maine

Maine’s one-to-one laptop program provides an ideal opportunity to explore conditions that optimize teacher integration of technology-focused curriculum into the classroom. EcoScienceWorks (ESW) is an ecology curriculum that includes targeted simulations and a code block programming challenge developed through an NSF-ITEST grant. The project was designed as a collaboration that included simulation software developers; middle school science teachers; the Maine laptop program; environmental educators; an external evaluator; and a lead organization experienced in teacher guided curriculum development. Thus, each of the elements of TPACK (technology, pedagogy, and content knowledge) worked together to produce the final ecology simulation-centered curriculum. In 2008–2009, the ESW curriculum became available statewide through the Maine laptop program. Partner teachers have transitioned their classrooms to more learning-centered environments through the use of technology and have become teacher leaders. The collaborative approach to technology focused curriculum development used in this project is a model for TPACK professional development.
