Does monitoring and evaluation seem too technical? Are you grappling with logframes and indicators that don’t adequately tell the story of your program? A Theory of Change (ToC) approach can help. This course will provide you with a ToC toolkit to help assess any process of change that you may be developing. It is optimized for public and development managers, monitoring and evaluation practitioners, donor agencies, NGOs, academics, and other stakeholders. A ToC approach helps you situate complex social and development interventions. ToC is both a process and a product for explaining the various contributors to change, and the multiple levels of outcomes that result from program implementation. The course will introduce you to thetheory of change approaches and principles. It will give you the tools to both understand existing theories of change as well as develop your own. You will also be able to connect a theory of change to logframes and other organizational tools for further monitoring and evaluation.

It is easy to fall into the trap of thinking that you need to write in a complex style to express complex ideas. In fact, complex writing styles can obscure meaning and tire your readers.This short course is aimed at students at tertiary institutions, and contributors to academic publications. It will help you to articulate complex ideas with clarity and meaning.The first week of the course focuses on developing a structured writing process, appropriate for your intended readership. We discuss when to write, the importance of a golden thread, the main principles of drafting a research report, and different abstract patterns.The second week zooms in on the principles of paragraph and sentence construction. You will learn ways of writing that enhance clarity and engage your readers.
Clinical acid-base chemistry forms an integral part of the education of medical professionals, and is essential for the management of many patients in an acute care setting. Traditional approaches to this topic make use of over-simplified arguments which introduce a number of ambiguities and explanatory inadequacies. In this course, you will learn about Stewart’s model and how it uses a formal solution equilibrium approach which facilitates a clearer understanding of the process.A number of clinical examples are given to illustrate the power of this approach and the contrast with the more traditional teaching of the subject.
Led by some of the world’s leading authorities in the field, this course provides an introduction to the role of forced and precarious labor in the global economy. Building upon content from the widely acclaimed online platform ‘Beyond Trafficking and Slavery,’ it explores how vulnerable workers – whose conditions are frequently compared to slavery – routinely endure precarious pay and conditions in order to generate goods and services further up the economic chain. The course will explore how various kinds of exploitation have been classified – as modern slavery, human trafficking, or forced labor – and consider some of the effects of using the language of slavery to describe the abuses that are happening today.The primary focus of the course will be migrants and workers. Students will learn how patterns of exploitation are linked to economic and political interests. They will be invited to consider the strengths and limitations of different models of intervention and protection. Drawing upon examples from across the world, the course will specifically focus on labor in three major categories of work: supply chain work, migrant work, and sex work. Students will be asked to consider how these categories' connections to global economic and political forces create patterns of vulnerable, precarious, and forced labor. The course will also consider the limitations of popular approaches focusing upon the politics of rescue, and instead consider alternatives based upon models of worker rights, collective organizing, and decent work. All migrants deserve protection as migrants. All workers deserve protection as workers. Modern slavery and human trafficking campaigns selectively focus upon a small minority of vulnerable migrants, and a small minority of precarious workers. These cases are the tip of the iceberg.This course should appeal to anyone interested in both better understanding and effectively challenging global patterns of exploitation, vulnerability, and abuse.
In this course, you will learn the basics of results-based project management. After an introduction to the results framework and its associated performance indicators, you will learn how monitoring systems and evaluations provide a crucial source of evidence for management decision-making.This project management course is designed to address the growing demand for managers in Africa and around the world, who can use results-based approaches to design, implement and manage an ever growing range of programs and projects. Monitoring and evaluation (key results based management tools) are increasingly called upon within public service, non-governmental sectors and multi-lateral development agencies to help ensure that resources are put to optimum use and that citizens and beneficiaries are assured of receiving the benefits that are committed to them.The course has been developed in partnership with CLEAR Anglophone Africa and draws upon the centers experience in promoting the use of evidence-based systems across Africa to enhance development practice.

Whether you work in molecular biology, clinical medicine, health policy, or any other health-related field, this course will equip you to investigate the effects of time delays, feedback and system structure. You will learn how to interpret the causes of typical system behaviors such as growth, decay and oscillation in terms of the underlying system properties, and to rapidly develop computer-based models and run simulations to gain insight into the problems in your domain.This course will empower you with a deeper understanding and an enhanced capacity to achieve useful interventions in healthcare.
This course will provide you with conceptual models for understanding, and engaging with, digital transformation processes. Digital transformation is impacting strategy and operations across business and government organisations. This is a current and rapidly unfolding process. Because it is driven by new (and yet to be invented) technologies and applications, the process is inherently disruptive and its outcomes cannot be predicted. However, there are models which can help us think about and engage with the process. Digital transformation is comprised of multiple social, economic and organisational components, which makes it difficult to describe and monitor the process. The ‘Digital Diamond’ provides a model for clustering multiple components into the four key elements of any digital transformation process, making it possible to consider the overall direction of digital transformation in an organisation. As digital technologies are incorporated into business processes, organisations strive to maintain a dynamic equilibrium between ‘chaos’ and ‘order’, agility and stability. The ‘Complex Adaptive Situational Model’ (CASM) provides a way of understanding the complexities of change in networked organisations. Well managed digital transformation offers the promise of added value. But where and how is this value created? The ‘Generic Value Chain’ identifies the processes for creating and maintaining value through the IT function. As digital technologies are incorporated into a range of business functions, the role of the IT function is changing. The concept of ‘business technology’ helps us understand this shift, and reconceptualise the role of the CIO team in organisations that require high levels of digital literacy across business functions. Together, familiarity with these models and conceptual frameworks will allow you to engage with digital transformation processes in your own sector and organisation.
