The Department of Education’s Students’ Ongoing Research In Educational Studies (STORIES) Conference is an annual student-led conference which supports postgraduate students from around the globe in their ongoing research and fosters networking among students and faculty. This year, STORIES will take place as a two-day free, online event to be held on 14th & 15th of March 2022 (9:00-17:00 GMT).

With social twists, political turns, and medical breakthroughs, the past few years have irrevocably altered educational research. From COVID-19 to Black Lives Matter to the technological impacts of video conferencing on children in schools, never before has research, activism, or student-oriented pedagogy applied so extensively to teaching and learning. As researchers and students, we have each uniquely and personally been impacted by events that have influenced our simultaneously globalized and hyper-localized worlds, and we want to hear about it. From the way children develop language and identity to federal education laws, it is fitting that the STORIES theme this year is “Global and Communal Perspectives on Language, Educational Policy and Pedagogy.”

Chief Executive Officer, CAMFED
Yidan Prize for Education Development Laureate 2020
Member of the Yidan Council of Luminaries

Ms Lucy Lake is the Chief Executive Officer of CAMFED and has pioneered strategies to increase school retention and learning among marginalized girls, benefitting over six million young people.

People often talk about girls’ education in terms of secondary benefits: lower birth rates, better family health. But as leaders of CAMFED – the Campaign for Female Education – Lucy and fellow luminary Angeline Murimirwa know it’s about much more than that. Girls’ education is the foundation of social justice.

CAMFED evolved from a scholarship program launched by Ann Cotton in Zimbabwe in the early 1990s, which challenged the received wisdom of the time: that families didn’t want their girls in school. “We set out to prove that if you took poverty out of the equation, girls would be in school alongside boys,” says Lucy.

Since proving just that, they’ve since launched the 157,000-member strong CAMFED Association, supporting girls on their educational journey post-graduation, and mentoring young women to address big challenges in their societies. And they’ve expanded their work into Ghana, Malawi, Tanzania and Zambia.

CAMFED also brings data, evidence, and research findings directly from communities where they work. When they meet with policymakers, they use that data to enfranchise communities and reinforce government accountability to every marginalized girl. “Enfranchisement within communities in relation to the school system ultimately creates the context for girls to succeed,” says Lucy. CAMFED’s model means solutions are local, cost effective, and supported from many angles – it’s easy for ministries of education to move from resistance to champions.

Lucy sees the council’s potential for challenging more outmoded and unfair beliefs and practices in education systems around the world. As she puts it: “everyone in the group has demonstrated how they think differently, and that there’s an opportunity to move away from some of the more traditional models of education.”

Executive Director Africa, CAMFED
Yidan Prize for Education Development Laureate 2020
Member of the Yidan Council of Luminaries

Ms Angeline Murimirwa is CAMFED’s Executive Director – Africa. She is uniquely positioned to bring the expertise of young women once excluded from education to inform policy and strategy at every level.

Together with Lucy Lake, Angeline is part of the first team to become Yidan Prize laureates. She’s also a beneficiary of the organization she now helps lead, having been among the first Zimbabwean girls to get a CAMFED scholarship.

Her experience was bittersweet. When she came top in her primary school class, she cried – not out of happiness, but overwhelm: her family couldn’t afford to support her through secondary school.

CAMFED helped shoulder that financial burden, and Angeline bonded with 20 other girls with a similar experience. Next, the organization started bringing scholars together at national events to build a stronger network in what would eventually become the CAMFED Association.

“If one girl drops out, we raise hell and turn every stone until we understand everything that is happening,” says Angeline, adding that “putting the child at the center was a rude shock for most government systems we work with.” With more than 157,000 members in the Association, CAMFED has helped women exercise their agency at all levels of society, from village communities to inter-ministerial committees, bringing the perspective of the most marginalized to the table. “It’s the sense of purpose that makes it what it is,” says Angeline.

Angeline also knows the impact of being a decision-maker who has experienced marginalization. “I dream of a time when more women are occupying leadership positions…when there are more decision makers who understand intimately and personally what it means to be marginalized… they are not co-opted. They are equal participants in decision making, meaning there is inherent understanding from the top.”

Founder and Director,
Fundación Escuela Nueva (FEN)
Yidan Prize for Education Development Laureate 2017
Member of the Yidan Council of Luminaries

Ms Vicky Colbert is founder and executive director of Fundación Escuela Nueva. The education model she espouses has benefited students in more than 20,000 rural schools in Colombia, and has been adopted in 19 countries.

Escuela Nueva was built on Vicky’s twin beliefs: vulnerable children have a right to quality education, and quality education for all is the best way to solve inequality. Her work has demonstrated – first in Colombia, now around the globe – that with the proper support, even small rural schools can create active and personalized learning.

Successful education, she believes, isn’t just about language and math, but social and emotional skills: self-esteem, cooperative learning and peaceful behavior. “We need to balance the heart and the mind.”

It all starts with the people in the schools. For years, she says, policy makers focused on improving education through administration and management. But the real way to strengthen education systems, Vicky believes, is using teachers and students as the “agents of change”, and the schools as the unit of change.

Vicky focuses on the ideas of great education thinkers like John Dewy, Maria Montessori and Lev Vygotsky, among others – but in a practical, cost effective and replicable way. These thinkers highlighted the relationship between learning processes, citizenship and democracy.

Escuela Nueva trains teachers using the same methods they’ll use with their students. They visit demonstration schools to see Escuela Nueva in action – and to see that change is within reach. And then there’s ongoing support for them through teachers’ learning circles.

Professor of Physics and Graduate School of Education and DRC Chair
Stanford University
Yidan Prize for Education Research Laureate 2020
Member of the Yidan Council of Luminaries

Professor Carl Wieman is a pioneer of the use of new pedagogies in STEM education on college-level science teaching. His work has transformed the way STEM education is taught in major universities around the world.

As a Nobel Prize laureate, Carl doesn’t just think about physics; he thinks about how people learn to think like physicists. He’s noticed problems in the career path: academic performance isn’t a good indicator of how a student will fare as a practicing physicist. And what’s often misidentified as science talent actually is just a reflection of the quality of someone’s education. Carl believes we should teach students how to make good decisions – like experts do.

“Learning to use certain knowledge and reasoning processes to make decisions, that’s what good education is fundamentally about – learning to make better decisions in your life.”

Carl believes we can improve teaching by taking a scientific approach. And he’s demonstrating that in his research. In one study, he found that students retained only 10% of information from physics lectures after 15 minutes. Then he applied the learning principles he’d uncovered in his research: working collaboratively, making decisions, solving problems and taking feedback. Afterwards, students retained 90% of the information after two days – as well as more than doubling their conceptual understanding and improving their outlook on physics and problem solving.

He also thinks that we should challenge the belief systems of university professors. Professors tend to sort students into those they believe have more talent and less talent, even in the most select universities. But what if they believed every student could be successful when given the right kinds of educational opportunities?

“Effective teaching is a science, just like medicine. Students are all human beings. They all have the same basic biology and so learn fundamentally the same way. A doctor can’t just say: I’m not going to try and cure that person because I don’t think they have the right biological talent to get well.  Teachers should not do this either. ” For Carl, we need to focus on how students learn, and which practices most effectively support the success of all.

Chairman of the Department of Statistics,
Northwestern University
Yidan Prize for Education Research Laureate 2018
Member of the Yidan Council of Luminaries

Professor Larry Hedges is one of the most influential applied statisticians in the world. With so many education studies around (often coming to contradictory conclusions), it can be difficult for policymakers to act on the evidence in front of them. Larry’s methods give these policymakers tools to sort through the studies and understand what works.

More generally, Larry’s goal is to help transform the loose-knit study of education into a more rigorous science – one that accumulates, interprets and applies knowledge through testing. Using that approach, he’s known for shedding new light on subjects likes class size and school funding.

Larry sees three ways to strengthen educational research: creating rigorous methods for research; training researchers; and improving how research findings are shared.

He compares this the movement for evidence-based medicine – when double-blind, randomized control trials and systematic reviews were established. Could similar methodological standards help educational researchers improve the reliability and generalizability of their work – and fuel change in the classroom, too?

Larry supports Donald Campbell’s vision of an “experimenting society”. Rather than rolling out the thing that’s going to change the world at once, test programs in a few places, see if they work and under what conditions, make improvements, and learn “how to do these things that you’ve never done before.”

He also notes that wealthy countries have the resources to help deal with the challenges of education in poorer countries, but they need the political will. They need to understand that it’s not about altruism, but fixing (instead of exacerbating) inequality. After all, the biggest challenges we face today are global: just look at climate change.

Walter H. Gale Professor of Education,
Harvard Graduate School of Education
Member of the Yidan Council of Luminaries

Professor Thomas Kane is an economist and Walter H. Gale Professor of Education at the Harvard Graduate School of Education. His research has greatly influenced policymaking on a vast number of education policy topics.

The instructional choices teachers make—rather than curriculum or class size—is the primary driver of student learning.  For at least four decades, researchers have documented large differences in student achievement gains in different teachers’ classrooms.   And, yet, teaching has been viewed as an “art”, beyond the realm of science.  As a result, we know surprisingly little about the relationship between specific teaching practices and student learning gains.

With the support of the Bill & Melinda Gates Foundation, Thomas led the Measures of Effective Teaching Project (MET) to lay the foundation for a science of teaching.  The MET project collected videos of 3,000 teachers at work in the classroom. From this pool, they identified the teachers and teaching practices associated with the largest gains in student achievement. After measuring differences in teaching practice, they randomly assigned teachers to different groups of students to see if the relationships were causal.

Sure enough, the most effective teachers in the first year also had students performing better than average in the second year.

“Some will say great teaching is an ‘art,’ not science. It’s certainly true that individual teachers find unique ways to motivate and inspire students… Nevertheless, we showed that it’s still possible to describe and measure general principles underlying effective teaching practice. That’s essential, because in order to improve student achievement on a broad scale, we need to incorporate those principles into teacher training and teacher feedback. The MET project was just a start: we need to keep pushing our understanding of what makes for effective teaching.”

For Thomas, the greatest challenge in education is that we don’t systematically evaluate reform proposals on a small scale before rolling them out broadly.  Just as we cannot always predict how pharmaceuticals will affect the human body, the ways students learn – and the ways teachers change their teaching – are too complicated to anticipate every obstacle and side effect. He thinks the key is in creating a research infrastructure to support widespread, continuous trials of reform ideas: “the first education system that can test many ideas at once and scale up the ones that work – that system will outpace all the others.”   They will also more quickly shed those ineffective practices that linger because of tradition or conventional wisdom.

Thomas supports the idea of a three-way partnership between education authorities like school districts, researchers, and non-profits – getting together to share evidence, training and materials.

Vincent van Hees: Measurement of physical activity and rest using R-package GGIR
The emergence of raw data accelerometry in research has provided the opportunity to collaborate more easily across research disciplines. However, the raw data collection also introduced a need for effective tools to process this kind of data. In this talk I will present R package GGIR and present an overview of how it works and motivate the main decisions that were made. I will cover: error reduction, decisions on how to aggregate the data, meaningful segmentation of the time series, and the sustainability of open source software tools like GGIR.

Elina Ketonen & Visajaani Salonen: From raw biosignal data to user friendly data for experience sampling studies
Data processing is an important part of studies dealing with biophysiological sensors (e.g., activity/gravity, heart rate). Depending on the set frequency (Hz) of the sensors, we accumulate large amounts of raw data (e.g., 100 Hz gives 100 reports per second). For commercial products the raw data contains little or no information about how to process the data, as such algorithms can be protected by business secrecy. Visajaani Salonen’s task as a methodology specialist is to manipulate raw-signals or company manipulated data into an aggregated format to preserve as much information as possible about the participant and his or her activity or heart rate. In this presentation we describe how we collect, manage and process biosignal data to link with experience sampling method (ESM) data in the “Bridging the GAPS “study carried out at the University of Helsinki. In total 139 Finnish secondary school students participated in the study, for two weeks.

We processed biophysiological data from Polar activity bracelets and FirstBeat health-monitoring sensors (two sensors applied to the chest). The Polar bracelet produces aggregated activity/sleep data in the form of Metabolic Equivalent of Task (MET) values for 30 second intervals. The FirstBeat health-monitoring device produces one-second interval data for heart rate and many additional variables pre-calculated from heart rate variability. FirstBeat also produces a list of RR intervals (intervals between successive heartbeats), serving information about participants’ level of stress and recovery. Data from both devices need to be aggregated into longer epochs in order to achieve a more reliable description of states of heart rate or activity.

An interesting, and largely unknown challenge is within which time-window we can merge self-reports from experience sampling with aggregated biophysiological measure. Would it be the experience (e.g., positive emotions at Time T) associated with a certain level of activity within a time-window that is five minutes wider (± 5 min) than the self-report, or would ± 10 min or ± 15 min be reasonable? In addition, what is the most efficient data analytic method to do this? We compare several data processing methods, for example time interval mean, standard deviation, Gaussian meaning [Costa, 2012], nonlinear dynamics [Voss, 2009] and continuous time-modeling [Voelke, 2012]) for aggregating physiological data to match the ESM time points. These procedures are possible to carry out using the R-statistical programming language. The testing of the different data-processing options as well as some preliminary empirical findings regarding biophysiological correlates of students’ self-reported experiences are presented in the seminar.

Helen Dawes & Patrick Esser Objective measurements of Physical Activity in adolescents – a recent UK example in ~10K students
Current society is moving less and less, resulting in reduced fitness levels leading to detrimental health status as visible from increased obesity rates.  Recent reports have shown that 1 in 5 pupils in reception are overweight or obese. By year six, this has increased to ~35% of pupils making the UK one of the most obese and least fit countries in the world. The Government’s Childhood Obesity Plan for Action (2016) calls for the education and encouragement of healthy living and promotes the minimum of an hour of physical activity (PA) per day. However, children and adolescents are meeting these recommendations only in 18-27%.

Within this session, we highlight subjective and objective measurements of PA ranging from self-report diaries to the emerging trend of using wrist-worn accelerometers. We will discuss a novel analysis pipeline of PA, in addition to providing examples of applications within studies assessing (the lack of) PA in physical education classes in 100+ schools (~10,000 students) within the UK.

About the Speakers
