STEPP -- Scaffolded Training Environment for Physics Problem-solving -- is an environment created by a multidisciplinary research team for students in introductory physics courses to learn physics concepts, modeling and computational thinking in a synergistic manner.

In STEPP, students and teachers build physics simulations based on problems in their own curriculum using a modeling tool based on finite-state machines (state diagrams).

Three STEPP Modules on 1D kinematics, 2D kinematics and Newton’s laws of motion, and have been built and field tested at high schools and the University of Texas at Dallas.

STEPP Modules are:
Carefully scaffolded for novice learners
Multi-representational
Grounded in research on teaching and learning of physics

STEPP Modules are a web app ready to run in a web browser on a laptop or a desktop computer.

The modules posted below aim to provide digital resources for students and instructors. Providing students on-demand digital, multimedia, open-access resources which can be watched repeatedly at convenient times can serve as one path to improving student success in introductory physics courses The modules have been created for each topic covered in calculus-based introductory physics courses. Each module includes:Videos reviewing the laws and concepts, and videos with step-by-step problem solving providing students with additional aid in learning the material. (i) Review Videos summarize major topics after students had encountered them in class and highlight their application to common and significant problems. This resource incorporates explanations, derivations, and demonstrations to illustrate a concept; (ii) Problem-Solving Videos present detailed solutions to multi-step questions which students might encounter when working through textbook problems or on major summative assessments. This in-depth approach was structured to guide students in improving their problem-solving skills and techniques, as well as address common mistakes. More than one hundred videos have been created for different types of learners. This is a resource for both students and instructors.Textbook-independent homework problem sets that could be implemented via LMS. The homework has a mix of multiple-choice and free-response problems aiming to develop student critical thinking. Detailed solutions to all problems are provided so that the students can compare their results with the solution, or an instructor can understand what was intended for the solution if modification of the problem is desired. This is a resource for both instructors and students. Video demonstration experiments for each topic that will allow the instructors around the State of Texas to bring physics experiments to their classrooms (instructor resource). The videos merely show the experiment taking place without any explanation of the underlying physics. This gives the instructor complete freedom to tailor the explanation to their class. A text with a brief description of the experiments is provided. 

Review Videos summarize major topics. This resource incorporates explanations, derivations, and demonstrations to illustrate a concept.

University Physics is a three-volume collection that meets the scope and sequence requirements for two- and three-semester calculus-based physics courses. Volume 1 covers mechanics, sound, oscillations, and waves. This textbook emphasizes connections between between theory and application, making physics concepts interesting and accessible to students while maintaining the mathematical rigor inherent in the subject. Frequent, strong examples focus on how to approach a problem, how to work with the equations, and how to check and generalize the result.
