The free online course Introduction to E-Learning Theory and Practice is an overview of internationally recognised and research-based e-learning theory and methodologies for creating effective e-learning courses. The course begins by reviewing what is meant by the term &quot;e-learning&quot; and what the benefits are in creating e-learning content. The course then reviews the Cognitive Theory of Multimedia Development, how learning occurs in a multimedia environment, and how to identify relevant course material using topic analysis and task analysis methodologies. You will learn about the importance of writing learning outcomes first when creating a course, and how to write learning outcomes about specific aspects of the course that describe a competency or performance capability that is to be acquired by the learner. Next you will learn how to storyboard a course using presentation techniques such as storytelling, a scenario-based approach, a demonstration-practice method, or a toolkit approach. Finally, you will learn how to create different types of assessments that monitor and evaluate student learning. This free online course will be of great interest to teachers, trainers and all subject matter experts who would like to learn more about the theory and practice behind designing and developing effective e-learning courses.<br />

The free online course in Introduction to Ecology provides detailed information about the different types of ecosystems, terrestrial and aquatic biomes, and the effects of climate change on biodiversity. The course first introduces you to the scope of ecology and biogeography with a focus on the distribution of plant and animal species and their impact on the terrestrial environment. You will learn how to differentiate between ecological patterns and processes at different scales and levels of biological organisation (population, community and ecosystem). Next, you will learn to identify and recognize the distinguishing characteristics of terrestrial and aquatic biomes. You will gain an understanding of what controls animal and plant distribution, abundance and biodiversity. You will learn how plants and animals absorb energy and nutrients from the ecosystem around them as well as how species interact with each other. You will learn about the biology of various habitats from marine and freshwater to terrestrial habitats and the soil. Finally, you are introduced to climate and the effects of global climate change where you will learn about the interaction between humans, animals and the environment with specific reference to the effects of modern technological advances. You will gain an understanding of the role ecology plays in conservation, wetland and natural resource management, forestry, agriculture and fisheries, as well as the climatological challenges faced by society. The course will be ideal for professionals working in the area of biology, ecology or environmental science, for students who wish to pursue a career in the sciences, or for those who simply want to learn more about building a sustainable existence on this planet. This course will also be of great interest to anyone who would like to learn more about ecological diversity and the distribution of organisms in the global ecosystem around them or those who are concerned about their impact on the environment. <br />

A country’s economy consists of three major economic agents; consumers, firms and government. Analyzing the choices made by these economic agents is one of the main subjects of microeconomics.

In this economics and finance course, you will learn how the decisions made by economic agents are represented in the market as demand and supply of commodities. You will also learn about equilibriums in the market, which is when the quantity demanded is equal to the quantity supplied. The derivation of this equilibrium is another main focus of microeconomics. By deriving an equilibrium in a market, we can see at which level the price will be and how much of a transaction will occur.

Since this is an introductory economics course at the most elementary level, no prior knowledge of economics is needed. Anyone who is interested in economics is welcome to take this course.

In this economics course, you will learn some of the major concepts of macroeconomics, such as gross domestic product, price level, inflation, unemployment, economic growth and the balance of payments.

You will see that macroeconomics is not that different from microeconomics, in that the interaction of supply and demand provides the basic organizing framework for analyzing the workings of a national economy. You will learn how the equilibrium levels of national income and prices are determined at the intersection of aggregate supply and aggregate demand curves, just as the equilibrium quantity of transaction and price of an individual commodity is determined at the intersection of supply and demand curves.

This is an introductory course at the most elementary level so no prior knowledge of economics is required.

An introductory course on teaching and learning science and mathematics in a variety of K-12 settings. Topics include education and media, education reform, the history of education, simulations, games, and the digital divide.

This class uses K-12 classroom experiences, along with student-centered classroom activities and student-led classes, to explore issues in schools and education. Students in this course spend time each week observing pre-college math and science classes. Topics of study include design and implementation of curriculum, addressing the needs of a diversity of students, standards in math and science, student misconceptions, methods of instruction, the digital divide, teaching through different media, and student assessment.

An introduction to several fundamental ideas in electrical engineering and computer science, using digital communication systems as the vehicle. The three parts of the course—bits, signals, and packets—cover three corresponding layers of abstraction that form the basis of communication systems like the Internet.

The course teaches ideas that are useful in other parts of EECS: abstraction, probabilistic analysis, superposition, time and frequency-domain representations, system design principles and trade-offs, and centralized and distributed algorithms. The course emphasizes connections between theoretical concepts and practice using programming tasks and some experiments with real-world communication channels.

This course is an introductory subject in the field of electric power systems and electrical to mechanical energy conversion. Electric power has become increasingly important as a way of transmitting and transforming energy in industrial, military and transportation uses. Electric power systems are also at the heart of alternative energy systems, including wind and solar electric, geothermal and small scale hydroelectric generation.
