Physics Classroom is making strides to make our site accessible to everyone. Our site contains 6 navigation areas. The Primary, Secondary, and Page Level navigations have a screen reader version of their nav structure that allows using the left and right keys to navigate sibling navigation items, and up or down keys to navigate parent or child navigation items. The others can be navigated using tabs. The Primary Navigation handles the first 2 levels of site pages. The Secondary (which is not always available) handles the 3rd and 4th level of structure. The Page level navigation allows you to navigate the current page's headings quickly. The Header Navigation contains the Light/Dark Mode toggle, Search, Notifications and account login. The Breadcrumb Navigation contains the breadcrumb of the current page. If the current page has a breadcrumb, you can get to it by skipping to the content and tabbing in reverse (shift plus tab). The Footer Navigation contains links such as Privacy, Contact, about and terms. Some resources contain an Audio Player that can be activated by holding down the T key for 3 seconds, and then using K to pause and resume. While not every area of Physics Classroom is usable purely from keyboard and screen reader, we are committed to continue work on making this possible. If you have questions or need additional help, please use this link to contact us.

Who Can See Who? Notes

Notes:

The Who Can See Who? Interactive is an adjustable size file that displays nicely on tablets such as the iPad, on Chromebooks, and on laptops and desktops. The compatibility with tablets such as iPads and with Chromebooks make it a perfect tool for use in a 1:1 classroom. This Interactive does not display well on all smart phones and The Physics Classroom does not recommend its use on all smart phones.

Teaching Ideas and Suggestions:

The Who Can See Who? Interactive is a skill-building tool that allows the user to explore images in plane mirrors. Given a plane mirror and the position of five students, learners must determine which student(s) can be seen be each individual student. When a learner makes a decision as to who can see who, feedback is immediate and explanations are provided with a ray diagram. The built-in score-keeping makes this Interactive a perfect candidate for a classroom activity. The Interactive provides an invaluable formative assessment of how and why a person can view an image in a plane mirror. The law of reflection and the ability to locate an image are prerequisites to this Interactive. The intention is that after labwork, instruction, and some plane mirror ray diagramming practice, a classroom could navigate to Who Can See Who? and use the Interactive as an assessment/learning tool. The Interactive addresses the common misconception that a person can see whomever is positioned directly in front of a plane mirror. The availability of the stars on the main menu allows a teacher to quickly check-off progress on a per-student basis (if desired).

Our Who Can See Who? simulation is now available with a Concept Checker. Do the simulation. Then follow it up with the Concept Checker.
