Alejandro Gangui, Maria Iglesias, Cynthia Quinteros

摘要:

关于天文学的一些主题的教学活动序列,主要涉及日晷投射的阴影的长度和方向,一年中不同季节白天阴影的运动,以及寻找真正的天文北,已经完全发展。它还包括从不同的参考系和科学史上的一些主题的意见,以丰富学生之间的辩论,以及太阳和日晷的明显位移的简化模型的建设,并作为资源,讨论学生中发现的一些常见的误解的讨论。为中学教师在课堂上实施这些活动提供了多方面的建议和明确的指导。

英文摘要:

A didactic sequence of activities on some topics of Astronomy, related mainly with the length and orientation of shadows cast by a gnomon, the movement of shadows during daytime in different seasons of the year, and finding the true astronomical North, is fully developed. It also includes a discussion of observations from different frames of reference and of some topics in the history of science to enrich a debate among students, as well as the construction of a simplified model for the apparent displacement of the Sun, and of a sundial, and their use as resources to discuss some common misconceptions found in students. Multiple suggestions and clear guides are given for teachers of secondary education to implement theses activities in their classes.
