Teaching and Learning Electromagnetism in Introductory Physics Courses - In the workshop it will discuss the impact of physics education research on electromagnetism in the educational designing and practice of physics teaching at university level. Two of presentations will present studies about students' difficulties of learning topics of electromagnetism such as electromotive force, electromagnetic induction or Faraday's law. It will present also a study about the problems of teaching Maxwell equations in relation to cognitive theories. Finally, a study on developing students' mathematics' techniques involving the meaning of the physics concepts will be discussed. Organizer: Jenaro Guisasola

- emf as a force that does work or has energy
- confuse emf with voltage difference
- belief potential difference produce emf
- electromotive "force" is not a force.
- emf is the external work expended per unit of charge to produce an electric potential difference across two open-circuited terminals. The electric potential difference produced is created by separating positive and negative charges, thereby generating an electric field. The created electrical potential difference drives current flow if a circuit is attached to the source of emf.
- A source of emf can be thought of as a kind of charge pump that acts to move positive charge from a point of low potential through its interior to a point of high potential. … By chemical, mechanical or other means, the source of emf performs work dW on that charge to move it to the high potential terminal. The emf ℰ of the source is defined as the work dW done per charge dq: ℰ = dW/dq.
