As part of Nuffield CESS’s continued commitment to the training and mentorship of junior experimentalists, we are excited to announce our next introductory course on oTree. This course aims to introduce students and researchers in the social sciences to oTree, a leading framework based on Python to develop and administer experiments in the social sciences. The course is best suited for absolute or semi-beginners, as it does not assume any prior knowledge of programming either in Python or in any front-end language such as JavaScript, HTML, CSS. Over the span of the course, participants will develop the skills necessary to program experiments of simple-medium complexity and the groundwork to feel confident working with the oTree framework.
