Science plays a crucial role in your decisions as you go about your daily life. The representatives you elect and the legislation you vote on influences science legislation, limits and funding. This class will teach you fundamentals of modern biology to help you make more informed voting decisions.

As you learn the fundamentals of Biology, we'll explore the scientific issues sparking political debate: 

• Evolution vs. creationism
• Reactions to pandemic disease
• The risks and benefits of vaccination 
• How extinctions impact the planet
• Space exploration and the search for extraterrestrial life
• Sexual behavior

We look forward to engaging course discussions about how each vote in a democracy affects the way biology functions in your everyday life.

How do we understand the notion of space? How have urbanisation, mobility, digital spaces, and globalization changed the way we perceive it? This course aims to help you feel comfortable with the notion of space. The simplest way to understand it is to connect your daily life, your perceptions and your practices to the concepts of contact and remoteness. In SpaceX, we will explore together the city, urbanisation, urbanity, and urbanism, the individual actor in a globalising World, the emerging digital spatialities, the space-time couple, and the complex relation between societies and bio-physical worlds. Moreover, we will see that cartography is a powerful tool. By the end of the course, we will enable you to not only read but also draw your own maps. Finally, the issues of action on space through spatial agency and spatial justice will be addressed. In each of the nine sessions, a recognised specialist will be filmed in a particular place—a ‘thinking place’—throughout the World, to help us simultaneously inhabit and understand space.

Despite all the remarkable technological breakthroughs that we have made over the past few decades, the threat from infectious diseases has significantly accelerated. In this course, we will learn why this is the case by looking at the fundamental scientific principles underlying epidemics and the public health actions behind their prevention and control in the 21st century.

This course covers these four topics:

1. origins of novel pathogens;
2. analysis of the spread of infectious diseases;
3. medical and public health countermeasures to prevent and control epidemics;
4. panel discussions involving leading public health experts with deep frontline experiences to share their views on risk communication, crisis management, ethics and public trust in the context of infectious disease control.

Urology is the clinical science of diseases within the genitourinary system of males and females. Anatomically it includes diseases in the upper urinary tract like the kidneys and ureters, the lower urinary tract like the urinary bladder and urethra, and the male inner and outer genitals like the prostate, testicles and the epididymis.
 
Many of the symptoms from these organs belong to the top 100 most common symptoms for which patients seek help. This course will set you on a path to a basic understanding of the most common symptoms from the genitourinary system.

You might think that urology merely is a surgical specialty but that opinion couldn’t be more wrong. Today urology is a speciality including numerous new and common non-surgical and pharmacotherapeutic alternatives. Our goal for participants taking this course is to gain knowledge and instill confidence in basic clinical reasoning within the urological field.
 
The course will include clinically relevant cases.

Louv1.1x and Louv1.2x together give an introduction to all major programming concepts, techniques, and paradigms in a unified framework. We cover the three main programming paradigms: functional, object-oriented, and declarative dataflow.

The two courses are targeted toward people with a basic knowledge of programming. It will be most useful to beginning programming students, but the unconventional approach should be insightful even to seasoned professionals.

Louv1.1x covers fundamental concepts. You’ll learn functional programming, its techniques and its data structures. You’ll use simple formal semantics for all concepts, and see those concepts illustrated with practical code that runs on the accompanying open-source platform, the Mozart Programming System.

Louv1.2x covers data abstraction, state, and concurrency. You’ll learn the four ways to do data abstraction and discuss the trade-offs between objects and abstract data types. You’ll be exposed to deterministic dataflow, the most useful paradigm for concurrent programming, and learn how it avoids race conditions.

To learn more about the practical organization of the two courses, watch the introductory video.

This water sustainability course (PH242x) from Tufts University focuses on the engineering and public health components needed to achieve the conservation of safe water locally and globally. Together, we will explore how to create sustainable interventions geared towards improving population health.

This course provides an interdisciplinary framework for understanding the place of water in health policy and engineering by delving into the complex social, economic, political and scientific factors that influence how we approach these critical health and water related challenges. 

We identify threats to our water supply, including climate change, urbanization, agriculture and emerging contaminants. We lead a water sampling field trip and analyze the results in order to understand how water quality is assessed and regulated. We learn how to conduct a “Risk Assessment” as it relates to human and environmental health. The class will debate about issues such as water privatization, social and environmental justice and hydrofracturing. We’ll learn about point of use interventions for local interventions and take a field trip to the massive Massachusetts Water Resources Authority to see firsthand how large scale interventions are built and managed. Lastly, we will learn about various anthological determinants that drive the sustainability of interventions, review strategies for water management in developing and developed countries, and discuss the opportunities and challenges with implementing these solutions.

In addition to lectures hosted by Tufts Professors Dr. David M. Gute and Dr. Jeffrey K. Griffiths, the course features field trips, and guest lecturers comprised of renowned water professionals, entrepreneurs and scientists from the fields of public health, engineering, environmental science and health policy.

We hope that your ability to conceptualize and address water-related issues will advance as a result of the lecture content, in class demonstrations and global dialogues. To achieve this goal, we strongly encourage active participation and discussion with the professors, students and water professionals from across the globe. 

Lastly, check out the content from The Biology of Water and Health – Fundamentals (PH241x), an archived course that provides a provocative introduction to topics such as the vital role of sanitation and hygiene, waterborne diseases, environmental epidemiology, and water contaminants.

Tufts University is proud to offer the two Biology of Water and Health courses (PH241x & PH242x) in partnership with the Open Education Consortium (OECx). All course content is openly licensed under a Creative Commons Attribution Non-Commercial Share Alike license.

Level Up! covers the complete Advanced Placement* Computer Science A course in unique and engaging ways. It's a significant change of pace from other online introductory programming courses. While you will rigorously learn the art of programming in Java, you will spend much of your time designing and writing games and simulations.  This course has no textbook because all the materials are online.  You’ll be reading; checking your understanding with self-tests; analyzing, modifying, and debugging code as well as writing it; and working with your fellow students to come to common understandings.  You’ll work with sounds and pictures (what do you sound like speaking backwards?), write adventure games and “smart” board games, and spend time trying to understand whole programs rather than just little pieces.
 
We’ve designed this course to help high-school students prepare for the Advanced Placement Computer Science test, and we’ll cover everything you need to know. It has been successfully used in classrooms for several years, and now its available for anyone, in school or not, through EdX. If you are an adult or a student who isn’t going to take the AP test, you are more than welcome to join!; We go beyond the minimum required by the AP committee, introducing graphics, mouse commands, and other tools for real programmers.
 
We based this course on the principles of “lab-centric” instruction, in which lectures are replaced by hands-on activities.  We won’t include long, fact-filled videos, and the webpages in this course will be your “textbook.”

This literature course will explore A Study in Scarlet, an 1887 detective mystery novel by Sir Arthur Conan Doyle. This novel introduced the iconic Sherlock Holmes and his friend Dr. John Watson. The book's title comes from a speech Holmes gives to Doctor Watson about his work, saying: "There's the scarlet thread of murder running through the colourless skein of life, and our duty is to unravel it, and isolate it, and expose every inch of it."

The story received little very public interest when it first appeared. In fact, only eleven complete copies of Beeton's Christmas Annual 1887 are known to exist. Many adaptations of Sherlock Holmes exist, however, and he continues to fascinate readers as an enigmatic detective.

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.

How can you help your students to see history as a living, breathing record of the past? How can you motivate students to ask probing questions and seek complex answers? How can you bridge their historical knowledge with a lifelong commitment to civic action?

With this self-paced course, middle and high school teachers will find new ways to engage students in and out of the classroom. Co-taught by Dr. Kathy Swan, Professor of Education at the University of Kentucky, and Naomi Coquillon, Manager of Youth and Teacher Programs at the Smithsonian’s National Museum of American History, this self-paced course will offer teachers useful and readily applicable strategies and tactics to incorporate inquiry-based learning methods into their existing history lessons.

The self-paced course brings together the new College, Career and Civic Life (C3) Framework for Social Studies with the Smithsonian’s hands-on, museum-based educational techniques that bring historical artifacts to life for millions of visitors each year. Through explanation, demonstration, and dynamic examples, the course offers teachers practical ideas for how to entice students to craft complex and incisive questions; think critically about primary and secondary historical sources; form and support their opinions with evidence; and communicate their conclusions in ways that will prepare them to be engaged citizens of the world. Demonstrations will feature the Smithsonian National Museum of American History’s exhibitions and vast collection of historical artifacts and will offer ideas and resources to help teachers everywhere incorporate object- and inquiry-based teaching techniques and Smithsonian online resources into their own classrooms.
