Physics LE Problem Features

Randomized Values

Physics LE problems utilize randomization of the numerical values used in the problem. This ensures that each student receives a unique version of the problem. Most problems have approximately 100 unique variations. This prevents plagiarism among students and makes it nearly impossible for students to search online for the answer to a particular problem variation.

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 varied 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) input of intermediate numerical values which need to be calculated to obtain the final answer.

Specific Feedback For all numerical answers specific feedback is provided to students using sophisticated algorithms which evaluate the following: correct numerical value (within a set tolerance), correct unit, order of magnitude errors, sign errors, and common misconception errors.

Numerical Problems and Multiple-Choice Questions In addition to numerical problems, the Physics LE Question Bank also contains multiple-choice questions. Multiple-choice questions are conceptual and also numerical in style, with numerical MC questions utilizing randomized values.

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.

Physics LE Lab Simulations

Ready-to-Go Lab Program Physics LE interactive simulations and accompanying lab exercises provide everything needed for an online lab course, covering all major topics in introductory physics. All simulations are accessed from within Physics LE and run full-screen inside a web browser making them compatible with all computers and devices.

Physics Lab Simulations Each interactive simulation accurately recreates the physical world allowing in-depth lab investigations to be carried out. Designed to be highly interactive and highly visual, users are given full control over relevant experimental variables allowing different scenarios and physical relationships to be investigated. The interactive simulations are also accessible in stand-alone format (without lab exercises).

Integrated Lab Exercises Lab exercises are integrated into each simulation and are comprised of numerical and multiple-choice style questions. Students are able to input answers to lab questions while simultaneously running the simulation. The exploratory questions guide the student through the process of making key observations and drawing conclusions. Students receive immediate feedback as they progress through the lab questions creating a dynamic learning environment. Student answers are evaluated using advanced algorithms and recorded automatically in the instructor gradebook.

Analytics & Gradebook

Analytics The Statistics & Student Results modules provide analytics at the individual and course level, allowing the instructor to quickly assess student performance on an assignment, quiz, or lab. This information can can help identify patterns and how well students are grasping the material. The following Statistics & Student Results reports help instructors 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 and places them in the proper category (e.g., homework, quizzes, labs, or a custom category). The desired weighting can be assigned to individual assignments & quizzes, with overall weighting assigned to categories. Grading curves can easily be established to automatically determine a letter grade. The Gradebook can be readily exported in a variety of formats.

Expert TA is easy to use, provides great value, and gets the job done at a better price; it really does a good job. The problems are a cut above what I have seen in other web-based homework. They are more complex and detailed. They have more different parts and each one of the problems addresses another aspect of physics. Hector Mireles, Associate Professor of Physics , California State Polytechnic University, Pomona, CA

I went with Expert TA because I had been using a publisher’s system and all of the answers to all of the questions were available on Google. Simon C. Capstick, Ph.D., Associate Professor, Department of Physics , Florida State University, Tallahassee, FL

Open online homework systems

A showcase presentation for #OTESSA21

Original proposal

The presence of online homework systems to support courses in mathematics, physics and chemistry has become ubiquitous over the course of recent decades (Bonham et al., 2001; Ziemer, 2004; Allain and Williams, 2006); the promise that these systems claim is the ease of assessment of student performance for the instructor in exchange for at least equivalent student learning. Many of these online homework systems are for-profit tools of publishers or independent providers of various sorts. These systems are not designed for long-term student benefit, but for corporate profit at the expense of availability of student performance data or access to learning materials beyond an academic unit of time. Kersey (2019) uses the phrase “closed educational resources” (CER) to describe these kinds of tools that provide only the most limited prospect of flexibility to share with others or edit course content.

Projects both historic (Martín-Blas and Serrano-Fernández, 2009) and recent (e.g. Hendricks et al., 2017; Kersey, 2019; LeBlond et al., 2019) have been undertaken to make online homework solutions available in the context of OER; however, most of the literature surrounding those efforts surround their efficacy at single institutions and do not extend to the point of sharing. It is proposed here that these efforts are merely the tip of the iceberg of many efforts of faculty to create their own homework solutions for their own courses without the benefit of credit for scholarship of teaching and learning. 

The author’s own discovery of OER came long after he started creating his own homework solutions for physics teaching and learning using the Moodle learning management system in 2007, and was inspired by early work he took advantage of for teaching and learning in chemistry in 2001 (DeLorenzo, Middle Georgia College, private communication); these experiences are representative of efforts of independent instructors working out their own solutions in the name of serving their own pedagogical needs.

This proposal’s primary purpose is the start of a conversation among independent instructors, both those cited here and others working independently, in the interest of building connection among instructors both within the open education community and those who are outside of the open education community (but within communities for sympathetic open source software projects; e.g., the Moodle project). A secondary goal of this proposal is the investigation amongst such instructors of centralized projects (e.g., the LibreTexts project, formerly known as ChemWiki; Allen et al., 2015) and the interrogation of the utility of such centralized projects for providing a means of sharing resources amongst one another. Ultimately, there need to be means for greater communication of faculty who have sharable resources with one another, and greater intention towards sharing those resources for the benefit of a wider community.

A Message for Teachers From The Physics Classroom

What's new at the physics classroom.

READ WATCH INTERACT

TEACHER TOOLS

PRACTICE REVIEW TEST

THE PHYSICS CLASSROOM TUTORIAL

A set of instructional pages written in an easy-to-understand language and complemented by graphics and Check Your Understanding sections. An ideal starting location for those grasping for understanding or searching for answers.

PHYSICS SIMULATIONS

The Physics Interactives includes a large collection of HTML5 interactive physics simulations. Designed with tablets such as the iPad and with Chromebooks in mind, this user-friendly section is filled with skill-building exercises, physics simulations, and game-like challenges.

PHYSICS VIDEO TUTORIAL

Our Video Tutorial provides a video-based alternative to the written Tutorial above. We aim to present relatively short, highly-organized presentations with a strong graphical component on discrete topics. Watch them on our site or follow the links to YouTube. We add videos quite frequently so stop back by if you don't find what you are looking for. Or subscribe to our YouTube channel,  tap the bell , and receive notifications when new videos come out.

MULTIMEDIA PHYSICS STUDIOS

A large collection of GIF animations and QuickTime movies designed to demonstrate physics principles in a visual manner. Each animation is accompanied by explanations and links to further information.

CONCEPT BUILDERS

Have you tried a Concept Builder lately? You should. This growing collection of cognitively-rich exercises will focus student attention on discrete learning goals. Filled with interactive elements, this section is the perfect tool for getting students thinking about the meaning of concepts. Perfect for students and 1:1 classrooms using iPads, Chromebooks, and the like. And for Chemistry types, we've added a large collection of Chemistry Concept Builders. 

MINDS ON PHYSICS - VERSION 5   

Minds On Physics - Version 5 is the HTML5 version of Minds On Physics that replaces our App and Legacy versions. Relying on a large bank of carefully crafted questions, Minds On Physics seeks to improve students' conceptions of physics. "MOPs" combines interactive questioning modules with a thorough, question-specific Help system to engage students in an exercise in thinking, reflecting and learning. Version 5 is our best-yet version of Minds On Physics. There is a fully functional free version and a paid version that integrates seamlessly with our Task Tracker system and offers some rather enticing features.  

THE CALCULATOR PAD

Version 2 of the Calculator Pad is now available. Our newest version includes >2500 Physics and Chemistry problems organized into >250 ready-to-use problem sets. Numerical information is randomly-generated. An answer box allows students to solve and check their answers. Most problems are accompanied  by an audio-guided solution that explains how to solve a similar problem while hilighting the habits that can be adopted for solving any problem. Teachers with Task Tracker accounts can modify problems and problem sets and even create their own problems. Task Tracker also allows teachers to assign problems to their students and track their progress. 

CONCEPT CHECKERS    

Concept Checkers were built to coordinate with the Physics Interactives section of our website. Relying upon our Task Tracker tool to deliver questions, check answers, and track student progress, a Concept Checker is designed to coordinate with an interactive simulation. Use it as a follow-up check to understanding after exploring the simulation. Most sims are accompanied by a Concept Checker. Some sims have Task Tracker code built into the simulation. But not all sims will have a Concept Checker.  Concept Checkers can be used with or without a Task Tracker account. 

THE SCIENCE REASONING CENTER

The Science Reasoning Center is our most recent upgrade. This section (once complete) will include more than 50 activities that are perfect for encouraging scientific reasoning skills. Students use science and engineering practices, combined with cross cutting science concepts and core ideas from the disciplines of physics (and chemistry) to analyze phenomenon, experiments, and data presentations. NOTE : We broke ground in April of 2023; we should have a large portion of content available by August of 2023. We will continue work throughout the 2023-24 school year.

THE REVIEW SESSION

A collection of pages with questions and answers/explanations which serve as reviews or practice. Each review complements a chapter from The Physics Classroom Tutorial.

PHYSICS HELP

A variety of question-and-answer pages which target specific concepts and skills. Topics range from the graphical analysis of motion and drawing free body diagrams to a discussion of vectors and vector addition.

ACT TEST CENTER

Calling all high school juniors: You've trusted The Physics Classroom to help prepare you for that unit exam in physics. Why not trust us to help prepare you for the biggest test of the year - the ACT test? That's right. Let the TPC help you with the ACT.

CURRICULUM CORNER

A collection of classroom ready worksheets for use by teachers with their classes. Pages are synchronized to readings from The Physics Classroom Tutorial and to assignments of The Minds On Physics Internet Modules. And now teachers can purchase The Solutions Guide containing complete answers, explanations and solutions to all worksheets. This is a section of great usefulness to teachers and of little interest to students. The Solutions Guide is available in two delivery options - a Digital Download and as a Compact Disc (CD).

QUESTION BANK

Writing good tests and quizzes for your physics class just got a whole lot easier! With The Physics Classroom's Question Bank, physics teachers can quickly put together multiple choice and free-response quizzes and tests that target concepts discussed at The Physics Classroom website. The Question Bank is available for purchase as a both a CD resource and as a Digital Download. Use of the Question Bank requires the Microsoft Word application. (Answers are NOT included on the Question Bank.)

NGSS CORNER

Our newest section, the NGSS Corner assists teachers of Physics and Physical Science in aligning their curricula with the Next Generation Science Standards. Numerous resources are identified and their alignment with the NGSS is described.

TEACHER TOOLKITS

The Teacher Toolkits provide teachers with packages of online resources (simulations, movies, animations, demonstration ideas, etc.) that are organized around a topic and a set of learning objectives. These resources, when combined with the numerous resources on our own site, allow teachers to plan high-quality, engaging instruction and to map out a curriculum that is NGSS-based.

THE LABORATORY

While you explore the approximately 150 labs here at The Laboratory, you will likely generate some questions about how they are used and how you can use them. This page, and the pages it links to, are hoped to provide some answers to those questions.

THE PHOTO GALLERY

The Photo Gallery provides teachers a toolbox of physics-relevant photos from the wealth of photos on Flickr. The Photo Gallery offers teachers three things: access to photos, organized by topic; a collection of nearly 30 galleries; and an invitation to join this exciting project of capturing and sharing physics phenomenon with a camera. Of course, students are welcome to participate as well.
