Frequently Asked Questions

 

How do students gain access to Physics LE?

Students can purchase a Physics LE access code at PhysicsLE.com. High Schools have the option to purchase a block of Physics LE access codes for distribution to students.

 

Do students need to know a particular course code or specific information pertaining to the course prior to purchasing an access code?

No, a Physics LE access code is universal and can be used one time to gain access to any course. When students first register at Physics LE they simply select their course from a list and enter their access code. (The course list shows the name of the school, name of instructor, and course name.) The Physics LE instructor gradebook will automatically populate with student names once they register.

 

Is there a fee associated with the instructor account?

No, there is no fee involved for the instructor account. The only fee is that associated with student access codes.

 

Is Physics LE appropriate for both high school and college/university physics courses?

The problems comprising the Physics LE library have varying levels of difficulty, providing ample problems for both high school and college introductory physics courses.

 

Is Physics LE compatible with all web browsers?

Physics LE is compatible with all standards-compliant web browsers. The following web browsers have been tested and are fully compatibile (latest browser versions): Chrome, Firefox, Safari, Edge, Internet Explorer.

 

What safeguards are in place preventing students from simply copying answers?

Physics LE numerical problems utilize random values assuring each student receives a unique version of the problem. Copying an answer from another student will result in an incorrect answer. A student must fully understand the problem and correctly solve it to receive credit.

 

Are significant figures carefully utilized in problems and also checked in student answers?

Significant figures are carefully displayed in every problem, especially when trailing zeros are involved, to make sure there is no unintended reduction in the number of significant figures appearing in the answer (e.g., situations such as 10 x 14.2 = 100 are always avoided, instead using 10.0 x 14.2 = 142). The system checks the student answer for the correct number of significant figures following standard significant figure rules for mathematical operations, and in certain special cases allows some leniency (see documentation).
