More than 2000 years ago, long before rockets were launched into orbit or explorers sailed around the globe, a Greek mathematician measured the size of the Earth using nothing more than a few facts about lines, angles, and circles. This course will start at the very beginnings of geometry, answering questions like "How big is an angle?" and "What are parallel lines?" and proceed up through advanced theorems and proofs about 2D and 3D shapes. Along the way, you'll learn a few different ways to find the area of a triangle, you'll discover a shortcut for counting the number of stones in the Great Pyramid of Giza, and you'll even come up with your own estimate for the size of the Earth.
 
In this course, you'll be able to choose your own path within each lesson, and you can jump between lessons to quickly review earlier material. GeometryX covers a standard curriculum in high school geometry, and CCSS (common core) alignment is indicated where applicable.

As contemporary humans, we are a product of our evolutionary past. That past can be directly observed through the study of the human fossil record, the materials preserved for archaeological study, and the DNA of living and extinct human populations. This course will provide an overview of human evolutionary history from the present--contemporary human variation in a comparative context--through our last common ancestor with the living great apes, some 5-7 million years in the past. Emphasis will be placed on major evolutionary changes in the development of humans and the methodological approaches used by paleoanthropologists and related investigators to develop that knowledge.

The course will begin by asking basic questions about how evolution operates to shape biological variation and what patterns of variation look like in living humans and apes. We will then look at how the human lineage first began to differentiate from apes, the rise and fall of the Australopithecines, the origin and dispersal of the genus Homo, and eventually the radical evolutionary changes associated with the development of agricultural practices in the past 15,000 years. Throughout the course students will be exposed to the primary data, places and theories that shape our understanding of human evolution.

Have you ever asked yourself what role land plays in front of demographic change, globalization or climate change?

Did you ever consider the connectivity between poverty and land access or changing land values? If you want to delve more deeply into these complex and fascinating issues, take part in our MOOC course, “Introduction Land Management.”

Land is a scarce and limited resource, which cannot be multiplied. It is a valuable basis for livelihood and for economic or ecological development. Land conflicts occur when people with differing interests run up against the declining availability of fertile land. Developing countries in general, and disadvantaged people in society are often the most affected groups. Yet, even industrialized countries face issues with sustainable land policy. As a result, experts in sustainable land management are desperately needed.

In this course, you’ll be introduced to the basics of land management. This MOOC gives you insight into basic functionalities and tasks of land management. It will help you recognize important land correlations with other fields of interest. You’ll understand contemporary global trends, necessary land related services, and the general process of executing land management interventions.

You learn why, when, and where sustainable land management is most needed and what the potential application fields of land management are. Exciting exercises, learning videos, discussions and literature recommendations accompany you through the course.

No previous knowledge of land management is required. 

Matrix Algebra underlies many of the current tools for experimental design and the analysis of high-dimensional data. In this introductory data analysis course, we will use matrix algebra to represent the linear models that commonly used to model differences between experimental units. We perform statistical inference on these differences. Throughout the course we will use the R programming language.

Given the diversity in educational background of our students we have divided the series into seven parts. You can take the entire series or individual courses that interest you. If you are a statistician you should consider skipping the first two or three courses, similarly, if you are biologists you should consider skipping some of the introductory biology lectures. Note that the statistics and programming aspects of the class ramp up in difficulty relatively quickly across the first three courses. By the third course will be teaching advanced statistical concepts such as hierarchical models and by the fourth advanced software engineering skills, such as parallel computing and reproducible research concepts.

These courses make up 2 XSeries and are self-paced:

PH525.1x: Statistics and R for the Life Sciences

PH525.2x: Introduction to Linear Models and Matrix Algebra

PH525.3x: Statistical Inference and Modeling for High-throughput Experiments

PH525.4x: High-Dimensional Data Analysis

PH525.5x: Introduction to Bioconductor: annotation and analysis of genomes and genomic assays 

PH525.6x: High-performance computing for reproducible genomics

PH525.7x: Case studies in functional genomics

This MIS course will cover supporting tech infrastructures (Cloud, Databases, Big Data), the MIS development/ procurement process, and the main integrated systems, ERPs, such as SAP®, Oracle® or Microsoft Dynamics Navision®, as well as their relationship with Business Process Redesign.

Management Information Systems (MIS) are an integral part of today’s professional landscape.

Grasping the key concepts in MIS does not need to be daunting. We will use real world examples to illustrate key concepts, and strive to strike a proper balance between clarity / amenity and conceptual soundness. Join us on this stimulating journey that will allow you to better understand and perform in your current or desired job.

A successful manager makes good decisions. To make good decisions, you need to understand the market forces that impact your business and personal life. This is true for managers in large multinationals or small businesses, in non-profit organizations or in the government. Individuals and households also make decisions. They decide on what to learn, where to work, how much to save, where to invest, and what goods to buy, among others. Most modern societies depend on markets to organize economic activity: they are market economies. A large number of decisions you make as individuals or as managers relate to markets. So it is important for you to know how markets work and how to make good decisions as a manager or as an individual operating in a market environment. This is what this course will teach you.

Most business schools have a course on Managerial Economics as part of the MBA curriculum. Exposure to Economics is essential for all students of management. This course will provide a simple introduction to Managerial Economics and use minimum mathematics.
