Chemistry Sim with accessibility features!Elements of the Molarity simulation include one beaker with liquid with corresponding solution concentration gauge, two interactive sliders for solution amount and solution volume, and a drop-down list of numerous liquids to choose from.

PhET Interactive Simulations has just published their first chemistry simulation Molarity with the following accessibility features:

  1. Alternative Input (or diverse input) – keyboard, touch, mouse, and VoiceOver gestures on iOS
  2. Sonification and Sound – meaningful sounds that help all students (option available to mute the sounds)
  3. Interactive Description – states and responses that are dynamic using screen reader software
  4. Interactive Description on iOS – states and responses that are dynamic using VoiceOver and its custom gestures

Alternative input and sonification are available without assistive technology (#1 & #2). To access interactive descriptions you will need to use the latest screen reader of your choice: VoiceOver, NVDA or JAWS and the appropriately paired browser Safari, Firefox, and Chrome (#3 & #4).

You can play with Molarity and use it in your learning journey for free at the following link: https://phet.colorado.edu/en/simulation/molarity

Open Educational Resources

Open Educational Resources (OERs) are research, teaching and learning materials that are free to use because they are in the public domain or have an open license. OERs are part of a movement to support equal access to education and lifelong learning for everyone. Many people, including educators, learners, and publishers are developing, adapting, remixing and sharing OERs. An OER is like a growing plant; each shared adaptation and remix is a new unfurling leaf making the OER plant more robust. Each new openly-licensed resource is like a new plant. The more robust and varied the OERs, the more sustainable the OER ecosystem. Learners can thrive in an OER ecosystem when we design OERs inclusively to benefit all learners.

Digital OERs

Digital resources come in many different formats including audio recordings, videos, written texts, or interactive simulations. An OER can be as simple as a digital document created with word processing (eg. Google Docs or MS Word) or as complex as modules made up of different content formats (eg. video and text), embedded interactive components (eg. calculators and simulations), and different methods of delivering learning (eg. multi-step quizzes).

Educators, resource creators, parents+guardians, let's ask for edu resources 2be accessible so ALL learners+their parents/guardians are included. If you create resources ASK for the tools2make them accessible; if you procure/have child in school, ASK 4 resources to be accessible
