Computer Science - Landscape Study - The Center for Elementary Mathematics and Science Education The survey yielded a rich, wide ranging set of findings. However, when considered together, those findings lead to three main conclusions: As a field, computer science education professional development needs to move toward more coherence. As a field, computer science education professional development needs to move toward better fitting the needs of the groups that will comprise the computer science teacher workforce. As a field, computer science education professional development needs to focus more on teaching and learning in the classroom.
Case study: A brief review of online visualisation tools that can help There is a growing range of online tools to help users their data. This brief review highlights four online visualisation tools that can help. The links page also links to lots more useful resources. Online tools that can help visualise data (these tools are free to use, but any data uploaded is typically then available on the system for other users) highlighted below include: On the resources and links page, we also link to free software applications and libraries for visualising data, and development languages for more sophisticated data visualisation.

Bullet graph A bullet graph is a variation of a bar graph developed by Stephen Few. Seemingly inspired by the traditional thermometer charts and progress bars found in many dashboards, the bullet graph serves as a replacement for dashboard gauges and meters. Bullet graphs were developed to overcome the fundamental issues of gauges and meters: they typically display too little information, require too much space, and are cluttered with useless and distracting decoration. The bullet graph features a single, primary measure (for example, current year-to-date revenue), compares that measure to one or more other measures to enrich its meaning (for example, compared to a target), and displays it in the context of qualitative ranges of performance, such as poor, satisfactory, and good. The qualitative ranges are displayed as varying intensities of a single hue to make them discernible by those who are color blind and to restrict the use of colors on the dashboard to a minimum.

The top 20 data visualisation tools One of the most common questions I get asked is how to get started with data visualisations. Beyond following blogs, you need to practise – and to practise, you need to understand the tools available. In this article, I want to introduce you to 20 different tools for creating visualisations: from simple charts to complex graphs, maps and infographics. Almost everything here is available for free, and some you have probably installed already. Advertisement
About John Snow John Snow is an iconic figure in epidemiology and public health, best known for his work on cholera, for a famous map, and for organising the removal of a pump handle in Soho. Less well known are his important contributions to anaesthesia and to epidemiological methods, and his engagement in public debates of the time. The breadth and depth of Snow’s activities provide a model for population researchers concerned not only with sound method but also with bringing their results to public benefit. Indeed, though epidemiology is often described as the study of health-related aspects of populations, its methods are applicable to studies of virtually anything in populations, and disciplines which now acknowledge the methods and terminology of epidemiology range from education to crime science and economics. Snow was born in York on 15 March 1813, one of eight children in a family of modest means. Snow described this work in the second edition of On the Mode of Communication of Cholera.
