In line with recent proposals for pedagogical sequences and<br \/>\nlearning progressions about core concepts and basic procedures in physics and astronomy education,<br \/>\nin this paper we suggest an intermediate, essential step in the teaching path from the local<br \/>\ngeocentric view of the Earth\u2013Sun system to a heliocentric one. With this aim we present data<br \/>\ncollected over a day and a year from an instrument we call the \u2018parallel globe\u2019, a globe positioned<br \/>\nlocally homothetic to the Earth. Some analyses are suggested, in particular of the phenomenon of<br \/>\nillumination of the Earth and its variations, that are consistent with the proposed instructional<br \/>\nobjectives.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Many researchers have documented the difficulties for learners of different ages and preparations in<br \/>\nunderstanding basic astronomical concepts.
