Currently, there is no agreement among scientists and science educators on whether heat
should be defined as a “process of energy transfer” or “form of energy.” For example …

In this work we present the design and assessment of a teaching sequence aimed at
introducing the principle of energy conservation at post-compulsory secondary school level …

Since teachers have a busy schedule, several studies show that teachers have difficulty in
incorporating students' pre-existing knowledge in their courses. For this reason, to get …
