Primary and derived parameters of common relevance of Astronomy, Geodesy, and Geodynamics [PDF]
Earth, Moon, and Planets, 1995 Problem of selecting primary parameters has been discussed. Primaries should be defined uniquely, as well as, physically. Since no unique definition for semimajor axis exists, it should be replaced by the geoidal geopotential valueW 0 or by the geopotential scale factorR 0 =GM/W 0, geocentric gravitational constantGM be also primary parameter.

Using a Sociocultural Approach in Teaching Astronomy Concepts with Children of Primary School
, 2014 This chapter describes the use of a social collaborative learning approach to teach astronomical concepts. We used a repeated measure design to test the effectiveness of a teaching intervention aimed at improving basic concepts of Astronomy. Results show that children after the didactical experience were able to give a detailed explanation of the ...

Science & Education, 2013
A great amount of research has been carried out worldwide to promote history of science as a powerful science teaching tool. Because the ways of choosing and using historical elements depend on teachers' or researchers' educational purpose, any attempt to support a single model-to-use seems difficult and probably irrelevant.

How Do Prospective Primary Teachers Exploit Typical Astronomy Textbook Images?
2022Previous work has shown that astronomy textbook images can be difficult for students to understand. The main reason for such difficulty lies in the fact the astronomical images are two-dimensional representations of three-dimensional phenomena. As such, some features of the phenomena may remain difficult for the students to understand.
