Feeding nine billion in 2050 without exhausting the planetary reserves is perhaps the greatest challenge mankind has ever faced. This course will examine the principles of production ecology and the ‘availability pillar’ of global food security that lie at the heart of food production. They can be applied to both crops and animal production. This course on the basics of crop production will discuss why yields in some parts of the world are lagging behind and identify the agro-ecological drivers that shape the wide diversity of production systems.
Furthermore, key issues relating to closing of yield gaps and how these link to different visions of sustainability will be explored.
This online course will be of great interest to international students and those with varied educational backgrounds, both professionally and culturally, to enrich their views and action perspectives related to global food security and food systems. Prof. Ken E. Giller will introduce you to crop production and underlying bio-physical principles in order to identify constraining factors in yield formation. He will explain how to assess yield gaps at the level of fields and production systems around the world, contributing to efficient resource management. Wageningen University and Research, through its unique systems-based approach to food systems, adds the phase of primary production to the broad context of global food security.
This course will help you envision how Indigenous histories, perspectives, worldviews, and approaches to learning can be made part of the work we do in classrooms, organizations, communities, and our everyday experiences in ways that are thoughtful and respectful. In this course, reconciliation emphasizes changing institutional structures, practices, and policies, as well as personal and professional ideologies to create environments that are committed to strengthening our relationships with Indigenous peoples.
For educators, this means responding to educational reforms that prioritize improved educational outcomes for Indigenous learners. In addition, educators must support all learners to develop their knowledge and understanding of Indigenous people’s worldviews and cultures as a basis for creating equitable and inclusive learning spaces. To support these goals, teachers, administrators, young people, school staff, and researchers will learn from Indigenous Elders, educational leaders, and culturally relevant learning resources as part of their experiences in this course.
For others who want to build their own competence and the capacity of those around them to engage with in relationships with Indigenous peoples based on intercultural understanding, empathy, and respect, this course will help get you get started in this process.

In Medieval Europe the Book of Hours, so called because its core component consists of the Hours of the Virgin, became the prayer book of choice for worshippers prosperous enough to commission or purchase such a book.
Although its contents were of monastic origin, literate lay readers were the most likely to use books of hours, as served not only as a prayer book, but also as a way of keeping track of the calendar, often doubling as a family chronicle.
Books of hours provide insight into broad patterns of piety marking the High and later Middle Ages, and through their choice of texts, images and added materials, inform us about the interior life and aspirations of everyone from kings and queens and lords and ladies to monks and nuns and, ordinary members of the patrician class, merchants and others.
In this course, we will explore how books of hours provide the closest thing we have to a comprehensive and continuous record of the development of painting across most of western Europe from the later thirteenth through the early sixteenth century.
“The Book of Hours” is one module of a series of courses called “The Book: Histories Across Time and Space.” You may take this course on its own, or with the other courses of the series.

Phenomena as diverse as the motion of the planets, the spread of a disease, and the oscillations of a suspension bridge are governed by differential equations.MATH226x is an introduction to the mathematical theory of ordinary differential equations. This course follows a modern dynamical systems approach to the subject. In particular, equations are analyzed using qualitative, numerical, and if possible, symbolic techniques.
MATH226 is essentially the edX equivalent of MA226, a one-semester course in ordinary differential equations taken by more than 500 students per year at Boston University. It is divided into three parts. MATH226.1 is the first of these three parts.
In MATH226.1, we will discuss biological and physical models that can be expressed as differential equations with one or two dependent variables. We will discuss geometric/qualitative and numerical techniques that apply to all differential equations. When possible, we will study some of the standard symbolic solution techniques such as separation of variables and the use of integrating factors. We will also study the theory of existence and uniqueness of solutions, the phase line and bifurcations for first-order autonomous systems, and the phase plane for two-dimensional autonomous systems. The techniques that we develop will be used to analyze models throughout the course.

How can we strengthen libraries and librarians in the advancement of knowledge, creativity, and literacy in the 21st century? Though libraries have been loved for over 3,600 years, their relevance in the digital age is being questioned, and their economic and social impacts are poorly understood. What is really essential about libraries and librarians, today and tomorrow? How can library members and all who support the mission of 21st-century librarianship raise the profile and support of these timeless values and services, and ensure universal access to the universe of ideas in all our communities? This course is based on what works. We’ll take an inspired, strategic, evidence-based approach to advocacy for the future of strong communities – cities, villages, universities and colleges, research and development centres, businesses, and not-for-profits.
We will cover:
- Values and transformative impacts of libraries and librarianship
- Research on current perceptions of libraries and librarians
- Role of relationships in advocacy
- Principles of influence and their impact on advocacy
- Strategic thinking and planning in advocacy
- Effective communication: messages, messengers, and timing
Guest speakers share their ideas, recommendations and successes. These leading advocates include, among others:
- Barbara Band, Emmbrook School, Berkshire
- Cathy De Rosa, OCLC
- Ken Haycock, University of Southern California
- Joe Janes, University of Washington
- Nancy Kranich, Rutgers University
- Victoria Owen, University of Toronto
- John Szabo, Los Angeles Public Library
Previous participants have said that this course – “showed me the value of building relationships,” and “made me approach our library’s advocacy much differently”, and “helped me see advocacy in a new light."
Advocacy is growing in urgency and importance on the agenda of all library associations. In this highly competitive environment, associations help their members and their communities to build advocacy capacity. This course meets that strategic need. It is offered in partnership with the Canadian Library Association and the American Library Association.

Everyone involved in higher education has questions. Students want to know how they’re doing and which classes they should take. Faculty members want to understand their students’ backgrounds and to learn whether their teaching techniques are effective. Staff members want to be sure the advice they provide is appropriate and find out whether college requirements accomplish their goals. Administrators want to explore how all of their students and faculty are doing and to anticipate emerging changes. The public wants to know what happens in college and why.
Everyone has questions. We have the chance to help them find answers.
Practical Learning Analytics has a specific goal: to help us collectively ponder learning analytics in a concrete way. To keep it practical, we will focus on using traditional student record data, the kinds of data every campus already has. To make it interesting, we will address questions raised by an array of different stakeholders, including campus leaders, faculty, staff, and especially students. To provide analytic teeth, each analysis we discuss will be supported by both realistic data and sample code.

This literature course will explore Mary Wollstonecraft Shelley’s 1818 horror classic, Frankenstein; Or, The Modern Prometheus. This novel is remarkable for a number of reasons, not the least of which is that Shelley wrote the novel when she was only 18 years old.
Frankenstein is a representation of both the Gothic and Romantic movements, and is often considered to be one of the earliest novels of science fiction as well. This story has had a huge influence on literature and popular culture, and has generated many adaptations in the forms of movies and plays. The first film adaptation, in fact, appeared in 1910.
Participants in this course will read, discuss, and write about the text and its influence. As in most book clubs, the focus will be on lively discussion. Course materials will include background information for understanding the text, as well as vocabulary and language support. Assessment will include quizzes and short writing assignments.
This is the third part of the BerkeleyX Book Club offerings.
WHAT IS “HOW STUFF MOVES”?
Mechanics is the study of how things move. It was the first quantitative science to achieve wide power to predict behavior, including things never before directly observed. Newton, Leibniz, and others invented calculus to describe motion and we will find both differential and integral calculus extremely useful throughout this course.
This is the first in a 3-part series of courses that parallels the second-semester mechanics course taught at Harvey Mudd College. Part 1 explores the concepts of momentum, force, and energy, and how these properties define the motion of objects at everyday speeds. Part 2 examines angular motion, and Part 3 examines wave motion. This course is an invitation to develop your problem-solving skills and to learn how to apply mathematics to all sorts of problems of the physical world. Learning the rules that govern how stuff moves in the world around us is exciting; using those rules to predict correctly something that you haven’t observed means that you really understand something. It‘s a great feeling.
WHAT SHOULD I KNOW BEFORE WE START?
You need not have taken physics before, but we assume that you have studied mathematics, up to and including a first course in calculus. You may be taking a calculus course concurrently with this course; that should be a good strategy. We will introduce important calculus ideas and methods as the need arises and provide examples.
There is a Mathematics Diagnostic Test that you can take at the beginning of this course to ensure that your mathematics background will set you up for success in this course.
Human rights are developed through the constant dialogue between international human rights bodies and domestic courts, in a search that crosses geographical, cultural and legal boundaries. The result is a unique human rights grammar, which this course shall discuss and question, examining the sources of human rights, the rights of individuals, the duties of States, and the mechanisms of protection.
We shall rely extensively on comparative material from different jurisdictions, to study a wide range of topics including, religious freedom in multicultural societies, human rights in employment relationships, economic and social rights in development, or human rights in the context of the fight against terrorism.
La finance est omniprésente et les décisions financières nous concernent tous. Tout individu est un jour ou l’autre amené à épargner ou emprunter. La sélection des projets d’investissements et leur financement sont des questions cruciales pour les entrepreneurs ou managers. D’une manière plus large, les décisions prises par le monde politique en matières financières influencent directement ou indirectement le quotidien des citoyens. Les récentes crises financières ont pu nous montrer à quel point il peut être primordial de comprendre les fondamentaux de la finance. Sans un minimum d’éducation financière, il est difficile d’appréhender le fonctionnement du monde dans lequel nous évoluons. Ce cours introductif vous propose un cadre conceptuel et des outils pour vous aider à prendre des décisions financières judicieuses, avec un focus particulier sur les opérations financières courantes.
Au terme de ce cours, vous serez capable de :
- Décrire les principes fondamentaux du raisonnement financier : absence d’opportunités d’arbitrage dans un marché concurrentiel, intégration de la dimension temporelle et du risque dans la décision financière ;
- Calculer des valeurs actuelles ou futures, de flux ou de séquence de flux ;
- Appliquer les techniques de l’évaluation actuarielle aux opérations financières courantes (de type épargne ou emprunt) et aux principaux actifs financiers (actions et obligations) ;
- Utiliser les différents outils de sélection d’investissement pour des projets en entreprise ;
- Analyser la problématique de la décision d’investissement, en tenant compte du lien entre rendement attendu et risque ;
- Déterminer le taux de rendement qu’une entreprise doit utiliser lorsqu’elle doit prendre une décision d’investissement et utiliser ce taux pour calculer la valeur générée par un projet ;
- Suivre des cours de finance plus avancés (finance d’entreprise, gestion de portefeuille, marchés financiers, finance internationale, produits dérivés, etc.).

This is a course for those who are interested in the challenge posed by massive and persistent world poverty, and are hopeful that economists might have something useful to say about this challenge. The questions we will take up include: Is extreme poverty a thing of the past? What is economic life like when living under a dollar per day? Are the poor always hungry? How do we make schools work for poor citizens? How do we deal with the disease burden? Is microfinance invaluable or overrated? Without property rights, is life destined to be "nasty, brutish and short"? Should we leave economic development to the market? Should we leave economic development to non-governmental organizations (NGOs)? Does foreign aid help or hinder? Where is the best place to intervene? And many others.
At the end of this course, you should have a good sense of the key questions asked by scholars interested in poverty today, and hopefully a few answers as well.
