All pages were found to use defined headings. This is excellent as it allows visitors and search engines to summarize the content of webpages quickly. Correctly defined headings aid accessibility and are particularly important for search engine optimization.
Some headings (4.0%) were found to be empty, or incorrectly defined. Empty or invalid headings are of no value to search engines and make a website less accessible.
- Make sure all headings have content which is relevant to the page of content.
Some pages did not define headings correctly. The H1 tag should be used for the most top-level heading, with H2 being used for sub-headings and H3 for further sub-headings and so-on. Not conforming to this convention may confuse visitors.
- Ensure that headings are defined in a semantically correct way, i.e. always start with a H1 tag. This is used to summarise the page content. Further tags (H2, H3, H4 etc) are meant to summarise and partition sections within the content.

ocw.mit.edu/course-lists/.../	description	The MIT Open Learning Library is home to selected educational content from MIT OpenCourseWare and [MITx courses](https://www.edx.org/school/mitx), available for free to anyone in the world at any time. #### How MIT Open Learning Library Differs from MIT OpenCourseWare and MITx on edX You can think of OCW, MITx, and Open Learning Library along a spectrum of learning scenarios, presenting content in different formats to meet different learner needs. - MITx courses are end-to-end course experiences with optional certificates available for you to earn, live teaching support and interaction with other learners in discussion forums, and start and end dates. - MIT OpenCourseWare offers a completely self-guided experience with published content from MIT courses that is open all of the time and licensed for download, remix, and reuse, but does not offer certificates nor interaction with teachers and learners. - MIT Open Learning Library sits in between MITx and OCW. As in many MITx courses, Open Learning Library provides interactive course experiences that include auto-graded assessments that give you instant feedback and allow you to track your progress as you work your way through the subject matter. And like OCW, this content is always open and self-guided and includes no live support, discussion forum, or certificates. MIT is committed to sharing learning materials with the world. The Open Learning Library provides additional opportunities to learn from MIT at your own pace, engaging with interactive problems and receiving instant feedback. #### Interactive Assessments and Progress Tracking You can view and use all Open Learning Library materials without enrolling ([learn more here](https://openlearning.mit.edu/courses-programs/open-learning-library)). If you want to track your progress through a course, create a free Open Learning Library account, and then enroll in the course. The learning experience will be similar to [MITx courses](https://openlearning.mit.edu/courses-programs/mitx-courses) running on edX and MITx Online platforms. However, Open Learning Library does not include discussion forums, certificates, or the ability to transfer your progress to an active MITx course. Open Learning Library resources designated as OCW content are free to download, remix, and reuse for non-commercial purposes. Resources designated as MITx content have varying licenses: some are All Rights Reserved, others Creative Commons, and some have mixed licenses. You will see the license type indicated on the About Pages.

ocw.mit.edu/collections/.../	description	Photo by Flickr user [Changhua Coast Conservation Action](http://www.flickr.com/photos/waders/). Seeking to understand and transform the world’s energy systems, MIT researchers and students investigate all aspects of energy. They discover new ways of generating and storing energy, as in creating biofuels from plant waste and in holding electricity from renewable sources in cost-effective, high-capacity batteries. They create models and design experiments to determine how we can improve energy efficiency at all scales, from nanostructures and photovoltaic cells to large power plants and smart electrical grids. They analyze how people make decisions about energy, whether as individual consumers or whole nations, and they forecast what the social and environmental consequences of these decisions might be. In fact, the study of energy is so important and so pervasive at MIT, the [MIT Energy Initiative](http://energy.mit.edu/) has devised an undergraduate [Energy Studies Minor](https://energy.mit.edu/education/undergraduate/minor/) which develops the expertise needed to reshape how the world uses energy. The Energy Studies Minor consists of a core of foundational subjects, complemented by a choice of electives which allow students to tailor their Energy Minor to their particular interests. Many of the Energy Minor subjects are represented on OCW, and listed below. In addition to its core and elective courses, some other energy courses which are not officially part of the Energy Minor program are also listed.

ocw.mit.edu/collections/.../	description	Massachusetts Institute of Technology has always been associated with major scientific and technological breakthroughs. But the breakthroughs alone do not explain the impact that MIT has had on the world. For that we have to look at entrepreneurship, which starts with the "Mens et Manus" (Mind and Hand) slogan on the Great Seal of MIT. For faculty, students, and alumni, MIT is all about making discoveries and inventions and then applying these discoveries and inventions to solve real problems. In a very tangible way, MIT faculty and graduates invent the future, and entrepreneurship—the building of new businesses—is often the road to that future. ![Title screen from the video, 'The Ecosystem: Nurturing Entrepreneurship at MIT'.](https://ocw.mit.edu/courses/entrepreneurship/ecosystem_slate2.png) [Watch this video introduction](https://www.youtube.com/watch?v=WSkDqpBctfA) to entrepreneurship at MIT. The report “[Entrepreneurship and Innovation at MIT](http://web.mit.edu/innovate/entrepreneurship2015.pdf)” examines the impact of MIT graduates who have founded and built for-profit companies. The report estimates that, as of 2014, living MIT alumni have launched more than 30,000 active companies, creating some 4.6 million jobs and generating $1.9 trillion in annual revenue. The cumulative result is the equivalent of the 10th largest economy in the world. This rich legacy of high-impact companies spans a wide range of industries; recent examples include A123 Systems, Akamai, iRobot, InVivo Therapeutics and Dropbox. The following courses represent a selection of the entrepreneurship-related courses offered at MIT. The courses are organized in two ways: Core courses, the starting points for entrepreneurs and Supplemental courses, important once the basics have been mastered Those interested in a general introduction to entrepreneurship as taught at MIT should visit [15.390 New Enterprises](https://ocw.mit.edu/courses/sloan-school-of-management/15-390-new-enterprises-spring-2013) and [15.S21 Nuts and Bolts of Business Plans](https://ocw.mit.edu/courses/sloan-school-of-management/15-s21-nuts-and-bolts-of-business-plans-january-iap-2014).

ocw.mit.edu/collections/.../	description	Like so many of the big challenges taken on at MIT, environmental and sustainability issues demand an interdisciplinary perspective. From declining fisheries to acute urban pollution to record-breaking global temperatures, the evidence of human impact on the environment continues to mount. And at the same time, the environment shapes us, as human society and institutions are built upon our connection to the weather, land, water, and other species. What can we learn from ecological systems and cycles? What solutions will allow people and the planet to thrive? MIT scholars, students and alumni are working to understand and help us make progress toward a more sustainable and just world. This core mission draws upon all of the fields represented at MIT: not just science, engineering, and technology, but also the humanities, arts, economics, history, architecture, urban planning, management, policy, and more. This OCW course collection is inspired by two interdisciplinary MIT programs. Many of the undergraduate courses fall within the [undergraduate Environment and Sustainability Minor](http://environmentalsolutions.mit.edu/environment-sustainability-minor/) managed by MIT’s Environmental Solutions Initiative (ESI); the OCW course list employs the undergraduate minor’s four topic pillars. Many of the graduate-level courses are part of the [MIT Sloan School of Management Sustainability Certificate](http://mitsloan.mit.edu/sustainability/sustainability-certificate) curriculum. Also check out the [MIT Climate Portal](https://climate.mit.edu) for many other Creative Commons-licensed open educational resources on climate change, including brief Explainer articles on key topics and the award-winning TILClimate podcast with educator guides.
