Development of E-Book for the Basics of Observing the Sky Object

Abstract

This electronic book (e-book) involves the horizontal coordinate system explanation and the basis of the sky object observation. We analyzed the astronomy cause description of the undergraduate level in many Universities and developed this e-book for the undergraduate students. The performance content accuracy of the book and the appropriateness of the question were checked by the experts for investigating the ItemObjective Congruence Index (IOC). The e-book was tried out with the undergraduate students. The samples users in this work are the undergraduate students who must learn astronomy in Chiang Mai Rajabhat University and Yala Rajabhat University. The result shows that the average satisfaction of students who performed this e-book is a very satisfactory level (4.80  0.40, overall). Therefore, the e-book for the basics of observing sky objects can be used as a teaching and learning media to develop effective teaching and learning which encourages learners to participate in teaching and learning via social media.
