The Declaration also emphasizes the need to establish an international network which will provide an efficient basis for the future cooperation within the teaching of astronomy in Europe. Another important point is the in-service education of teachers that is still lacking in many places. As an unfortunate consequence many teachers are unfamiliar with the more recent advances in astronomy and also unaware of the associated educational materials now available. Several of these were impressively demonstrated during the Workshop and a first, very useful exchange of materials and ideas took place among the participants.
Astronomy should contribute towards the consciousness that, in a complex society abounding in science and technology, a scientific education is essential for the choices that every citizen has to make in the
democratic life. Students should feel that the Earth is a wonderful place in the Universe, and to be cared for and defended.
The following particular goals are desirable:
(i). Astronomy education should be started as early as possible in the primary school and progress in the
following years. Through the media, students are nowadays exposed to a multitude of mainly unstructured impressions from the space sciences and associated areas; the teaching of astronomy in schools will establish the structure and the desirable organisational concepts.
(ii). By the end of compulsory education, students should have been involved in observation, experimentation and discussion of the following ideas from astronomy:
a. Our place in the solar system, progressing to our place in the Universe;
b. The nature of objects we see in our sky, for instance, planets, comets, stars, galaxies.
c. Examine thinking from the past ages and more recent times to explain the character, origin and evolution of the Earth, other planets, stars and the Universe.
(iii). In initial training of teachers and their subsequent in-service training, these ideas (iia - c) should be introduced and reinforced. Recent studies of students' misconceptions and ideas in astronomy provide a useful basis for the further development of teaching methods.
(iv). Since astronomy can provide a unique opportunity for fascinating, whole school activity, support should be provided for optional courses and extra-curricular work in astronomy.
(v). Astronomy teaching can contribute to an understanding of the physical laws which start from
the human level and reach the macro- cosmos to give a scientific organised outlook on our world and
appreciate the uniqueness of the Earth for the human race. Astronomy locates our niche in space and
time. Students should be aware of threats, from light pollution and radio interference, to our ability to
observe the night sky.
(vi). Astronomy teaching conveys the fundamentals of the scientific method, including the associated doubt and lack of answers and the interplay between experiment and theory, thereby forcing students to adopt a critical attitude towards the many pseudo-sciences.
(vii). Astronomy knows no national frontiers - the sky is the same above all of Europe - and the teaching of astronomy therefore contributes to international collaboration between students and teachers everywhere.
It is more likely that they brought the lunar month with them,taking it roughly as 30 days (30 12 = 360), than that theybegan with such an erroneous notion of the true length of thesolar year, seeing that in Egypt, above all countries in theworld, owing to the regularity of the inundation, the truelength could have been so easily determined, so soon as thatregularity was recognised. We must not in these questionsforget to put ourselves in the place of these pioneers ofastronomy and civilisation; if we do this, we shall soon seehow many difficulties were involved in determining the truelength of such a cycle as a year, when not only modernappliances, but all just ideas too, were of necessity lacking.
What we have to do in the present chapter is to see whetherthe orientation of the structures helps us with any suggestionstouching the question whether we have to stop at the placesnamed and acknowledge Egypt to be the true cradle of astronomicalscience; or whether the facts we have considered compelus to go a stage further back, and to recognise that the trueorigin was elsewhere; that, in short, astronomy, instead oftaking its rise in Egypt, was simply imported thither.
"We have already above (p. 90) attempted to explain thestriking phenomenon that the Bull and Pegasus, both with half-bodiesonly, ἡμίτομοι, enclose the Ram between them, by theassumption that the latter was interposed later, when thesun at the time of the vernal equinox was in the hind parts 401of the Bull, so that this point was no longer sufficiently markedin the sky. Another matter susceptible of a like explanationmay be noted in the region of the sky opposite to the Ramand the Bull. Although we cannot doubt the existence of aneastern balance, still, as already remarked (p. 68), theGreeks have often called it χηλαὶ 'claws' (of the Scorpion),and according to what has been said above (p. 312), the signfor a constellation in the neighbourhood of our Libra reads inthe Arsacid inscription 'claw(s)' of the Scorpion. These factsare very simply explained on the supposition that the Scorpionoriginally extended into the region of the Balance, and thatoriginally α and β Libræ represented the 'horns' of theScorpion, but later on, when the autumnal equinox coincidedwith them, the term Balance was applied to them. Althoughthis was used as an additional name, it was only natural thatthe old term should still be used as an equivalent. But italso indicates the great age of a portion of the zodiac."
