The water, sanitation and hygiene (WASH) sector is facing a shortfall of several million appropriately skilled professionals. Massive open online courses (MOOCs) can play a crucial role in addressing this. This paper presents the case study of the MOOC series “Sanitation, Water and Solid Waste for Development”, which has reached over 120,000 learners within six years. It has attracted mainly well-educated, employed learners, under 34 years old, from Asia, Latin America and Africa. Underrepresentation of female learners remains a challenge. While MOOCs have proven excellent for delivering WASH education at scale, some alternative formats (e.g. blended learning, small private online courses) allow more collaborative, interactive learning environments. Three practical examples from Nigeria, Indonesia and Mozambique indicate the potential for synergies among MOOCs and further learning formats. With the global shift towards digital learning due to the COVID-19 pandemic, MOOCs have gained further traction.

水，卫生与卫生（WASH）部门正面临数百万具有适当技能的专业人员的缺口。大规模的在线公开课程（MOOC）可以在解决这一问题中发挥关键作用。本文介绍了MOOC系列“卫生，水和固体废物促进发展”的案例研究，该系列在6年内已吸引了12万多名学习者。它吸引了来自亚洲，拉丁美洲和非洲的34岁以下的受过良好教育的，受雇的学习者。女学习者人数不足仍然是一个挑战。尽管事实证明，MOOC非常适合进行大规模WASH教育，但某些替代格式（例如，混合学习，小型私人在线课程）可以提供更多的协作，交互式学习环境。来自尼日利亚的三个实际例子，印度尼西亚和莫桑比克表明，MOOC和进一步学习形式之间可能产生协同增效。随着COVID-19大流行导致全球向数字学习的转变，MOOC受到了越来越多的关注。
