Physics LE is a robust online learning environment for physics, providing online homework and quizzes which utilize randomized variables, along with automatic grading and record keeping.



  • Physics question bank comprised of a growing collection of over 1600 questions for algebra-based introductory physics courses.
  • Assignments and quizzes can be quickly assembled and then made accessible to students online. Students create their own online account using a Physics LE Access Code.
  • All questions utilize random variables providing each student with a unique version of the question.
  • "Show your work" intermediate steps built into many questions to help guide students and provide a means to assign partial credit for student work.
  • Physics Fundamentals eTextbook by Vincent Coletta – the complete eBook is readily accessible within the Physics LE environment.
  • Physics question bank can be used to accompany Physics Fundamentals or any algebra-based physics course. Instructors are encouraged to submit new questions to add to the ever-growing collection.
  • Questions are graded automatically and recorded in the accompanying gradebook. Overview statistics are generated allowing the instructor to quickly assess student performance.
  • Physics LE is built on the Moodle platform offering numerous in-depth features along with a reliable and secure online environment.


Physics LE Question Bank

The 1600 questions in the Physics LE question bank cover a full-year of introductory physics. The extensive collection of questions offer wide versatility, along with varying levels of difficulty, to align with any algebra-based introductory physics course. Individual questions are categorized by general subject headings (acceleration in one-dimension, projectile motion, work and kinetic energy, electric fields, . . . ) to provide quick and easy correlation to your course.

Guiding Intermediate Steps
Rather than just requiring students to enter a final numerical value, many Physics LE questions incorporate guiding intermediate steps. Intermediate steps include assorted use of: 1) multiple-choice questions checking for understanding and problem-solving approach (using text or diagrams); 2) input of relevant equations or algebraic expressions; and 3) intermediate numerical values required to obtain the final answer. Students receive points for each intermediate step creating a system of partial credit grading.

Significant Figures and Units
All numerical questions require students to input their answer using the correct number of significant figures and the correct unit. Standard significant figure rules are utilized for multiplication/division and addition/subtraction, with some leniency with certain situations requiring the use of scientific notation (see documentation). The system is able to recognize equivalent answers using different metric prefixes.


Expanding Collection of Questions

The Physics LE question bank is continually growing with new questions being add on a regular basis. In addition, instructors are encouraged to submit questions they would like to have added to the question bank. Instructors simply need to submit questions in written form and the Physics LE team will do the coding.


Physics Fundamentals eTextbook

The Physics Fundamentals eTextbook by Vincent Coletta is built into Physics LE and accessible to every student at no extra cost. The eTextbook is comprised of 30 Chapters, 960 pages, and 1500 photographs and illustrations.

Dr. Coletta is a Professor of Physics at Loyola Marymount University in Los Angeles. His research in PER (Physics Education Research) has provided better understanding into student reasoning skills and strategies to address difficulties students encounter in learning physics.

Physics LE Statistics & Reports / Gradebook

The Physics LE Statistics & Reports modules allow the instructor to quickly review student performance on an assignment or quiz, this can can help identify patterns and how well students are grasping the material.

The following statistics and reports are generated:

  • Overall assignment or quiz - average score, median score, standard deviation, skewness, error ratio, and standard error. 
  • Individual questions - average score, standard deviation, intended weight, effective weight, and discrimination index.
  • Individual students - overall score and score for each question, as well as responses to individual questions.

The Physics LE Gradebook automatically records student scores in the proper designated category. Custom categories can be created with the desired weighting, and grading curves can be established. The Gradebook can be easily exported in a variety of formats.
