The domain of atomic physics is the field where most research on students' learning difficulties is available. The present study focuses on a simple example concerning the ways in which a highly structured form of cooperative learning – the jigsaw classroom – may work in the field of teaching atomic physics in secondary school.

A new electronic electroscope with a special design intended for wide audience classroom demonstrations and experiments on electricity is described. It operates as an electric charge sniffer by detecting slightly charged objects when brought in the front of its sensing electrode. The sniffer has the advantage of combining the high directional sensitivity with a logarithmic bar display. It allows for a identification of electric charge polarity during charge separation by friction, peeling, electrostatic induction, batteries or secondary coils of power transformers. Other experiments in electrostatics, such as observing the electric field of an oscillating dipole and distance dependence of electric field generated by simple charge configurations, are also described.
