Statistics 2 at Berkeley is an introductory class taken by about 1000 students each year. Stat2.2x is the second of three five-week courses that make up Stat2x, the online equivalent of Berkeley's Stat 2.

The focus of Stat2.2x is on probability theory: exactly what is a random sample, and how does randomness work? If you buy 10 lottery tickets instead of 1, does your chance of winning go up by a factor of 10? What is the law of averages? How can polls make accurate predictions based on data from small fractions of the population? What should you expect to happen "just by chance"? These are some of the questions we will address in the course.

We will start with exact calculations of chances when the experiments are small enough that exact calculations are feasible and interesting. Then we will step back from all the details and try to identify features of large random samples that will help us approximate probabilities that are hard to compute exactly. We will study sums and averages of large random samples, discuss the factors that affect their accuracy, and use the normal approximation for their probability distributions.

Be warned: by the end of Stat2.2x you will not want to gamble. Ever. (Unless you're really good at counting cards, in which case you could try blackjack, but perhaps after taking all these edX courses you'll find other ways of earning money.)

The fundamental approach of the series was provided in the description of Stat2.1x and appears here again: There will be no mindless memorization of formulas and methods. Throughout the course, the emphasis will be on understanding the reasoning behind the calculations, the assumptions under which they are valid, and the correct interpretation of results.

Mechanics ReView is a second look at introductory Newtonian Mechanics. It will give you a unified overview of mechanics that will dramatically increase your problem-solving ability. It is open to all students who meet the prerequisites (see right), but is especially designed for teachers and students who want to improve their existing understanding of mechanics.

Newtonian mechanics is the study of how forces change the motion of objects. This course begins with force, and moves on to straight-line motion, momentum, mechanical energy, rotational motion, angular momentum, and harmonic oscillators. Optional units include planetary orbits and a unit whose problems require multiple concepts to be applied to obtain one solution.

NOTE: New Section “Problem-solving Pedagogy”

We have developed a special approach to organizing the physics content knowledge and for applying it when solving problems.  This approach is called “Modeling Applied to Problem Solving” and has been researched carefully and has proven effectiveness for improving students’ performance in a later physics course on Electricity and Magnetism.

If you are a teacher looking to improve your knowledge of mechanics, or to learn new approaches to teach your students, we encourage you to sign up in the special teacher section featuring a discussion forum for teachers to discuss teaching ideas and techniques related to the topics discussed in this course.  To join these discussions,  verify yourself as a teacher, and we will sign you up in the teacher forum.

Note that this forum is exclusively reserved for teachers, so please do not register if you are not a teacher.

Teachers in the United States, and especially in Massachusetts, can receive extra benefit from this course. We offer Professional Development Points (PDPs) at no charge to teachers in Massachusetts who complete our course. If you are in a different state, we instead offer Continuing Education Units through the American Association of Physics Teachers. There is a fee for this certificate.

Course Syllabus

Note: Taking this Course Involves Using Some Experimental Materials

The RELATE group that authors and administers this course is an education research group, dedicated to understanding and improving education, especially online.  We showed that 8.MReV generated slightly more conceptual learning than a conventionally taught on-campus course  - but we were unable to find exactly what caused this learning.   (So far this is the only published measurement of learning in a MOOC).  This summer we will be comparing learning from different types of online activities that  will be administerered to randomly assigned sub-groups of our students.  At certain points in the course, new vs. previously used sequences of activities will be assigned to different groups.  We will then use common questions to compare the amount learned. Which group receives the new activities will be switched so that neither group will have all new activities.

Our experimental protocol has been approved by the MIT Committee on Use of Human Subjects.  As part of this approval we have the obligation to inform you about these experiments and to assure you that:

• We will not divulge any information about you that may be identified as yours personally (e.g. a discussion post showing your user name). 
• The grade for obtaining a certificate will be adjusted downwards (from 60%) to compensate if one group has harder materials.

Note: By clicking on the registration button, you indicate that you understand that everyone who participates in this course is randomly assigned to one of the groups described above. 

Welcome, and we hope you will both learn from and enjoy this course.

FAQs

Is there a required textbook?

You do not need to buy a textbook. All material is included in this edX course and is viewable online. If you would like to use a textbook with the course (for example, as a reference), most calculus-level books are suitable. Introductory physics books by Young and Freedman, Halliday and Resnick, or Knight are all appropriate (and older editions are fine).

What if I take a vacation?

The course schedule is designed with this in mind! Course contents are released four weeks ahead of the deadline, so even if you have a four-week vacation, you do not need to miss any deadlines and can still complete all of the material.

Will I get a certficiate?

Yes! This course awards certificates to all who satisfactorily complete the required portion of the course.

How are grades assigned?

There are three parts of the course that are worth points: Checkpoint problems that are folded in with the reading, Homework problems that come at the end of each unit, and Quizzes that are at the end of every 1-2 units. Each is worth a varying number of points, and you will not have to do every problem.

The course consists of 11 required units and three optional units. You do not need to complete the optional units in order to receive a certificate.

There is no final exam.

Should we clone humans? What should we think of the coming genetic revolution? How much control should we have over how and when we die? When does medical treatment turn into medical enhancement — and should we care? Is rationing health care good, bad, necessary — or all of the above?

This course will explore fundamental moral issues that arise in medicine, health, and biotechnology. Some are as old as life itself: the vulnerability of illness, the fact of death. Some are new, brought on by a dizzying pace of technology that can unsettle our core ideas about human nature and our place in the world. And nearly all intersect with issues of racial and gender equality, as well as policies affecting the world’s most vulnerable populations.

Designed to introduce students to the range of issues that define bioethics, together with core concepts and skills, this course should be of interest to undergraduates, health care professionals, policy makers, and anyone interested in philosophy or ethics.

What exactly are genetically modified organisms (GMOs) and why do scientists develop them? Studying the science of GMOs helps us understand biotechnology’s potential role in addressing challenges in agriculture.

In this introductory Food and Nutrition course, you will learn the basics of genetic engineering, explore the political debate around the GMO and review the arguments for and against their use.

We will study the politics surrounding the GMO and its impact at both an individual level and to society as a whole; including the problems, perceptions, benefits, and risks associated with GMOs. Important to understanding the complexities around this topic we will not only be looking at the science behind how the GMO works, but also to the limitations of this science. We will also discuss the importance of information literacy as a tool for effectively identifying and evaluating issues.

Our goal is that this MOOC will impact people's understanding of science, what it can and can't do, and how information is transmitted. The intent is not to influence how people feel about GMOs, but to give them the critical thinking and scientific literacy tools necessary to make informed decisions — and to understand the broader impacts of those decisions.

学这门课需要数学基础吗?

不需要，是算法课，不是数学课。有高中数学知识足矣。

这门课的程序用什么语言编写? 学这门课是否一定要会C++?

课堂的例程都是用C++编写的，要看懂需要一定C++的知识。至于完成作业，用C, C++, Java,Pascal语言都可以。

还是不明白算法到底有什么用。会各种编程语言不就行了吗？

语言只是实现算法的工具。没有好的算法，许多问题，计算机是不能够在人可以接受的时间内计算出结果的。各大IT公司招聘时往往会考察算法，而不是只问你会哪些语言。不会算法，掌握再多种语言，也很难说是一个好的程序员。

We encounter signals and systems extensively in our day-to-day lives, from making a phone call, listening to a song, editing photos, manipulating audio files, using speech recognition softwares like Siri and Google now, to taking EEGs, ECGs and X-Ray images. Each of these involves gathering, storing, transmitting and processing information from the physical world. This course will equip you to deal with these tasks efficiently by learning the basic mathematical framework of signals and systems.

This course is divided into two parts. In this part (EE210.1x), we will explore the various properties of signals and systems, characterization of Linear Shift Invariant Systems, convolution and Fourier Transform, while the next part (EE210.2x), will deal with the Sampling theorem, Z-Transform, discrete Fourier transform and Laplace transform. Ideas introduced in this course will be useful in understanding further electrical engineering courses which deal with control systems, communication systems, power systems, digital signal processing, statistical signal analysis and digital message transmission. The concepts taught in this course are also useful to students of other disciplines like mechanical, chemical, aerospace and other branches of engineering and science.

We will explore the psychology of our everyday thinking: why people believe weird things, how we form and change our opinions, why our expectations skew our judgments, and how we can make better decisions. We’ll discuss and debate topics such as placebos, the paranormal, medicine, miracles, and more.

You will use the scientific method to evaluate claims, make sense of evidence, and understand why we so often make irrational choices. You will begin to rely on slow, effortful, deliberative, analytic, and logical thinking rather than fast, automatic, instinctive, emotional, and stereotypical thinking.

We will provide tools for how to think independently, how to be skeptical, and how to value data over personal experience. We will examine the mental shortcuts that people use and misuse, and apply this knowledge to help make better decisions, and improve critical thinking.
