Reciprocal learning across borders: Education as a bridge in turbulent times




ECNU Review of Education






In "Reciprocal Learning Among Chinese and Canadian Educational Cultures Amid Turbulent Global Relations," F. Michael Connelly and Shijing Xu (许世静) offer a timely account of how educators can maintain meaningful international collaboration during periods of political strain. They argue this process is potentially vital to the possibility of mitigating unproductive, ultimately dangerous, global tensions. Their article documents a long-term Canada–China educational partnership that continued to flourish even as the wider climate shifted from optimism toward tension and suspicion.

The article describes the Canada–China Reciprocal Learning Partnership in Teacher Education and School Education, launched in 2013, extended financially through 2024, and continuing through 2026 as the Teacher Education Reciprocal Learning Program at the University of Windsor as well as project publications continue and project friendships flourish. Supported by the Social Sciences and Humanities Research Council of Canada and participating institutions in both countries, the initiative connected universities, school boards, schools, teacher educators, researchers, teachers, teacher candidates, students, and families. Its purpose was not simply to compare two educational systems, but to create sustained opportunities for people in each system to learn with and from one another.

Two interconnected structures made this work possible. The Canada–China Sister School Network eventually involved more than 30 schools in Toronto, Windsor, Shanghai, Beijing, Changchun, and Chongqing. The Teacher Education Reciprocal Learning Program enabled Canadian and Chinese teacher candidates to undertake international school placements supported by preparation, guided reflection, and continued participation after returning home. Online meetings, classroom visits, co-planning, co-teaching, conferences, and collaborative research turned cross-cultural contact into shared educational practice

The authors describe their approach as Reciprocal Learning as Collaborative Partnership, or RLCP. Unlike versions of comparative studies that examine another culture from the outside, perhaps by using external detailed comparative research methods, RLCP is a study "with, not of," cultural partners. Participants work together on practical questions that matter in their own classrooms and institutions. Through these encounters, they learn about their international partners while also reconsidering their own assumptions and practices. Reciprocal learning therefore moves beyond the exchange of information: it depends on collaboration, self-reflection, and the integration of new insights into educational practice.

The study's methodology is best thought of as narrative in that rather than imposing common research frames to consistently apply across settings, the practical processes of teaching, learning and preparing for these matters drives the educational life conditions governing the collaborations. These ongoing, practical, educational life processes are the subject of study. The authors call this process narrative inquiry. The flexibility this process generates is uncomfortable for some, but rewarding in its relevance for the involved educational lives. Connelly and Xu understand educational experience as unfolding through time, relationships, and specific social and cultural contexts. Classroom events and participants' experiences are not treated as isolated observations or reduced to predetermined comparison categories. Instead, they provide openings for examining how practices developed, what they meant to participants, and where they might lead. This approach reflects the foundational view of narrative inquiry as the study of experience through stories and lived relationships. It is also collaborative and practice-oriented: researchers worked alongside educators, teacher candidates, and school communities rather than positioning them merely as objects of study.

The partnership generated substantial evidence of sustained activity, including six collaborative research teams, annual international conferences, approximately 130 journal articles, and a major Palgrave Macmillan book series. Yet its most important achievement may be relational. While political and media narratives increasingly presented Canada–China relations through a conflict lens, participants continued to exchange ideas, mentor teacher candidates, develop lessons, and publish together. Sister schools, exchange placements, shared leadership, research teams, and recurring conferences created a durable collaborative space without denying the surrounding political tensions.

The authors do not suggest that reciprocal learning eliminates disagreement or that it occurs automatically whenever people from different cultures meet. It requires time, institutional support, practical common purposes, cultural humility, and a willingness to reflect. Their account is hopeful without being naïve: it shows how educational relationships can endure beneath the turbulence of international politics and how collaboration can replace simplified cultural judgments with deeper understanding.

This article will be especially valuable to teacher educators, school leaders, comparative education researchers, policymakers, and those developing international partnerships. It presents education not as another arena for national competition, but as a form of patient bridge-building. At a moment of increasing global fragmentation, Connelly and Xu demonstrate that locally grounded, long-term educational collaboration can preserve trust, cultivate reciprocal understanding, and contribute to the larger aspiration of global harmony.

Chinese graduate students help transform Japanese universities as active contributors, not passive learners




ECNU Review of Education






International students are often discussed in terms of what they gain from studying abroad: degrees, skills, language ability, employability, and intercultural experience. A new study published in ECNU Review of Education shifts the focus to a different question: how do international students contribute to their host universities and societies?

The study, titled "How Do Chinese Graduate Students Contribute to Japanese Universities: An Agential Perspective," was conducted by Lilan Chen from Waseda University, Shuoyang Meng from the University of Tokyo, and Ming Li from the University of Osaka. Focusing on Chinese graduate students in Japan, the research argues that international students should not be viewed merely as recipients of education, but as active agents who shape academic knowledge, institutional connections, intercultural understanding, and the everyday internationalization of universities.  

Japan has long sought to attract international students as part of its higher education internationalization strategy. Since the 1980s, the Japanese government has implemented major policies to increase inbound student mobility, including targets of 100,000, 300,000, and more recently 400,000 international students. Chinese students have remained one of the largest and most important groups within this landscape. Yet existing research has largely focused on why international students choose Japan and what they experience after arrival. Less attention has been paid to what they give back to Japanese universities and communities.

To address this gap, the authors used collaborative autoethnography, a qualitative method that combines personal reflection, shared narrative, and collective analysis. Drawing on their own experiences as former or current Chinese graduate students in Japanese universities, they examined how international students contribute across four dimensions: academic–formal, academic–informal, nonacademic–formal, and nonacademic–informal.

The findings reveal that Chinese graduate students contribute to Japanese universities in multiple ways. In formal academic settings, they expand research agendas by bringing knowledge of China and transnational contexts into Japanese academic spaces. They also enhance Japan's global academic visibility through English-language publications, international conference presentations, and cross-border research collaboration.

International students also act as academic conduits between institutions. The study shows how Chinese graduate students help connect Japanese universities with Chinese universities through lectures, translation, academic introductions, and collaborative opportunities. These activities support knowledge diplomacy, not only between China and Japan, but also within a broader global academic ecosystem.

Their contributions are not limited to formal academic roles. In informal academic spaces, Chinese graduate students influence peers, junior colleagues, and supervisors by shaping research interests, encouraging international publication, and helping Japanese students participate in global academic networks. Their multilingual and multicultural experiences allow them to serve as network brokers who connect scholars across linguistic, disciplinary, and national boundaries.

Beyond academia, the study highlights students’ cultural and social contributions. Some participants taught Chinese language in Japan, introduced Chinese culture to local communities, and participated in city-level international exchange activities. Through these practices, they served as cultural mediators who helped Japanese students, residents, and communities develop more nuanced understandings of China and Chinese society.

The authors also emphasize that the effects of international student mobility travel in multiple directions. Chinese students' experiences in Japan influence not only Japanese universities but also families, friends, younger students, and academic communities in China. By sharing their experiences, advising future students, and maintaining transnational ties, they contribute to broader patterns of brain circulation and cross-cultural understanding.

"Our study suggests that international students are not simply moving through universities. They are also helping to reshape them," the authors note. "Their agency matters because internationalization is not only a policy target or institutional strategy. It is also produced through the everyday academic, cultural, and interpersonal work of mobile students."

The study calls on universities and policymakers to recognize international students as essential contributors to higher education. Rather than treating them mainly as learners, consumers, or future workers, institutions should create more supportive environments that value their academic, linguistic, cultural, and social roles. This includes providing opportunities for international students to participate in research networks, community engagement, intercultural education, and institutional internationalization.

In an era of demographic change, geopolitical uncertainty, and growing debates over the purpose of internationalization, the study offers a timely reminder: international students are not peripheral to universities. They are central actors in the circulation of knowledge, the formation of global academic communities, and the building of more open and connected societies.

The promise of quantum computing is to solve complex problems faster and more energy-efficiently than today’s supercomputers – from optimizing logistics processes to simulating molecules. This goal is coming within reach as the number of qubits – the computational units of quantum computing – increases. But in addition to technological challenges of scaling, there is another, less-considered issue: In the New Journal of Physics (DOI: 10.1088/1367-2630/ae6e68), researchers at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) demonstrate that in extreme cases, the so-called quantum Zeno effect can nearly halt computational processes as the number of qubits increases – a dreaded phenomenon comparable to a traditional computer “freezing”.

“The quantum Zeno effect is a previously overlooked obstacle to a certain class of quantum computers,” says Dr. Gernot Schaller, head of Quantum Technologies at HZDR’s Institute of Theoretical Physics. These so-called adiabatic quantum computers operate according to a special principle: Their qubits are always in their ground state, the lowest energy state. To solve a computational problem, the qubits’ energy landscape is gradually altered – slowly enough for them to adapt continuously and follow the changing ground state. Once the transformation is complete, the ground state immediately encodes the solution to the problem.

“Adiabatic algorithms are considered robust and can be executed by quantum computers largely independently of the hardware that is used,” explains Institute Director Prof. Ralf Schützhold. It therefore does not matter whether the qubits are generated using solid-state superconductors or individual ions confined in electromagnetic traps. Both hardware variants are already being used to test adiabatic algorithms that can be programmed elegantly and with relative ease.

When disturbances become an issue

“However, a quantum computer can only function properly if its qubits are not disturbed too much,” Schützhold emphasizes. Shielding against electromagnetic radiation and cooling to temperatures near absolute zero – minus 273.15 degrees Celsius – helps protect the qubits from such disturbances. Only then can they assume all possible states between zero and one – a property known as superposition. Their quantum-mechanical link, called entanglement, is also highly sensitive to external disturbances. Only the interplay of superposition and entanglement makes it possible to solve complex problems extremely fast.

“But despite all these measures, environmental impacts on the qubits can never be fully eliminated,” says Schützhold. According to the theoretical model developed by Schützhold’s team, adiabatic quantum computers become increasingly sensitive to disturbances as they scale up and the number of qubits increases. This is because the more qubits are linked, the smaller the changes in the energy landscape they must follow. “This is where the quantum Zeno effect kicks in,” says Schaller. Even tiny environmental influences can then affect the quantum states of the qubits. “Each disturbance acts like an unwanted measurement, slowing down the system’s evolution,” says Schaller. “In the worst case, a calculation could even freeze completely.”

To better understand the principle, let’s compare it with baking: A cake will only turn out right if it is allowed to rise in the oven undisturbed. If you keep opening the oven door to check if it’s done, you disrupt the baking process – the cake stays flat or even sinks. The quantum Zeno effect works in a similar way: Every disturbance disrupts the natural evolution of the quantum state. If this happens too often, the system will no longer be able to reach the desired final state. In the most extreme case, the computing process will nearly grind to a halt.

However, quantum computer developers can take action to mitigate the quantum Zeno effect, for instance by shielding against electromagnetic radiation and heat. In our cake analogy, this would be akin to putting a padlock on the oven door. Schützhold also proposes active measures to protect the process: “Using the spin-echo method, we can apply coherent pulses to reduce the coupling of qubits to their environment.” Back in the kitchen, the oven would rapidly heat up for brief periods to compensate for every time the door is opened. “Our study shows that we can only develop powerful quantum computers when we factor in environmental impacts from the very beginning,” Schützhold summarizes.

Many people are familiar with fossilised wood as a decorative item from the museum shop. However, the fact that it can preserve the geological history of entire regions spanning millions of years is a new discovery. A research team led by geologist Dr Steffen Trümper from the University of Münster has now demonstrated for the first time that fossilised wood is a natural archive, from which the geological history of an entire region over hundreds of millions of years can be deduced. The findings extend the previously known timescales of wood mineralisation. They show that fossilised wood can record the history of subsidence in a geological basin and reveal tectonic events on a timescale of hundreds of millions of years. Specifically, the study focuses on the Saale Basin, a sedimentary basin that formed around 300 million years ago in what is now central Germany and whose rocks are among the oldest in the large Central European Basin System. The study has been published in the journal Scientific Reports.

For their analysis, the researchers examined fossilised wood from the Kyffhäuser Mountains in northern Thuringia in Germany. The fossils, which have been known since at least the 18th century, comprise trunks up to 20 metres long that are embedded in fluvial redbeds – that is, reddish deposits from ancient river systems. Their colour results from embedded iron oxides, which relate to a warm, seasonally dry climate. The trunks, which were covered during floods, originate from tropical dry forests on the supercontinent Pangaea. At that time, the region lay close to the equator. Around 300 million years ago, the now-extinct relatives of conifers grew here. The Kyffhäuser is regarded as a reference site for a type of deposit that formed repeatedly in various basins across Europe. Together, these sites constitute one of the most extensive occurrences of fossilised wood in the Northern Hemisphere. The rocks are among the earliest deposits of the Central European Basin, an economically significant sedimentary basin system that still harbours raw materials, groundwater and potential for geothermal energy.

The key lies in the quartz, which has permeated and replaced the wood during the fossilisation process. Initially, dissolved silicic acid penetrates the dead wood, templating the cell walls and thus preserving the finest anatomical structures. Over millions of years, these initial siliceous deposits eventually crystallised into quartz, replacing the original tissue bit by bit. The study shows that the preservation of these fossils is far more nuanced than previously thought in terms of structure, geochemistry and the age of the quartz phases. The research team identified five successive generations of silicic acid. Each of these generations contains information about the temperature, pressure and composition of the solutions from which they formed. They document five stages spanning a period of 200 million years from the late Carboniferous to the Early Cretaceous. If the subsequent uplift to the Earth’s surface is taken into account, this period extends to as much as 300 million years. This is the longest documented sequence of successive wood mineralisation stages to date.

To analyse these ‘time capsules’, the team combined numerous techniques. Using quartz cathodoluminescence, fluid inclusions, oxygen and silicon isotopes, Raman thermometry, electron-probe microanalysis and scanning-electron microscopy, as well as so-called in-situ U-Pb dating – a geochronological method for determining the age of rocks and minerals – the five stages were reconstructed. “The tiny fluid inclusions in the quartz were particularly revealing, as they preserve information about the exact conditions during crystal growth,” explains Steffen Trümper. For example, the team demonstrated that parts of the wood were once located at a depth of three to five and a half kilometres at temperatures of 160 to 240 degrees Celsius.

The findings have significance that extends far beyond the Kyffhäuser. “It is astonishing that a fossil, often no bigger than the palm of a hand, encapsulates the geological history of an entire region spanning hundreds of millions of years,” says Steffen Trümper. “A sequence of five stages of mineralisation has never before been documented in fossilised wood. As fossilised wood occurs in many rock formations worldwide, this opens up a valuable source of information. It provides science with a new tool for tracing the evolution of continents.” However, the analyses show that the suitability of fossilised wood for basin analysis depends less on the tectonic setting and more on the climatic and sedimentological conditions during its burial.

In addition to the University of Münster, the Georg August University of Göttingen, the Karlsruhe Institute of Technology, the Museum für Naturkunde Chemnitz and the TU Bergakademie Freiberg were involved in the study.
