Physics LE Question Bank
 

Universal and Comprehensive

The Physics LE Question Bank is comprised of a comprehensive library of over 2000 problems for algebra-based introductory physics, covering a full-year course. The Physics LE Question Bank is universal — the extensive collection of problems offer wide versatility, along with varying levels of difficulty, to align with any algebra-based introductory physics course. Individual problems are categorized by general topic headings to provide quick and easy correlation to your course (e.g., acceleration in one-dimension, projectile motion, work and kinetic energy, electric fields, . . . ).

For users of Physics Fundamentals by Vincent Coletta, all chapter-end problems in the textbook are included in the Physics LE Question Bank.

 

Physics LE Problems


Intermediate Problem-Solving Steps
Rather than just requiring students to enter a final numerical value, many Physics LE problems incorporate intermediate problem-solving steps to help guide the student through the problem, also allowing partial credit to be awarded. 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 which need to be calculated to obtain the final answer.

Significant Figures and Units
All numerical problems require students to input their answer using the correct number of significant figures and the correct unit. Standard significant figure rules are employed for mathematical operations. The system is able to recognize equivalent answers using different metric prefixes.

Versatile Problem Behavior Modes
Based upon the desired objective for the assignment or quiz, the instructor can choose how students interact with problems: single attempt only, multiple attempts with no penalties, or multiple attempts with penalties.

Expanding Collection of Problems
The Physics LE Question Bank is continually growing with new problems being added on a daily basis. Instructors are encouraged to submit problems they would like to have added to the question bank—simply submit problems in written form and the Physics LE team will do the coding.

Physics LE Statistics & Reports
Physics LE 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 help teachers quickly capture insights into student performance:

  • Overall assignment or quiz - average score, median score, standard deviation, skewness, error ratio, and standard error. 
  • Individual problems - 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 category (e.g., homework or quizzes). 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.

 

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. The Physics LE Question Bank directly syncs with all problems contained in the Physics Fundamentals textbook.

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.
