The 1918 revised version of the book retained the organization and methodology of the original edition while incorporating updates based on scientific discoveries and educational experimentation. Certain topics were omitted from the revised edition. The Work and Energy major division was expanded to include electricity. An additional major section, The Earth in Relation to Other Astronomical Bodies, has been introduced. It discusses topics about the Moon, planets and comets, and the Sun and other stars. A list of Questions for Discussion was included at the beginning of each chapter, intended for teachers to read and discuss them briefly. These questions aimed to help students recall their previous experiences and establish new, relevant problems related to the book. According to the authors, they could serve as the best review of the material. The revised edition also includes fifty extra illustrations.
== Reception ==
=== Reviews === In the revised edition of The Elements of General Science, the authors claimed that the use of the course resulted in students feeling that they hadn't had any of the differentiated sciences (for example physics, chemistry or biology) and made them much more interested in studying these differentiated sciences in the future. The textbook was also taken positively by school teachers, mainly for the books effectiveness, simplicity and applicability in the everyday life, as stated by the reviews from 1915 and 1924. In 1920 and 1924 Caldwell, Eikenberry and Earl R. Glenn published a textbook Elements of General Science: Laboratory Problems, which was a new version of the 1915 laboratory manual A Laboratory Manual for General Science, which accompanied the general textbook. The new version of a laboratory manual appeared in 1924 and received immediate positive feedback for its practicality and engaging content. The first edition of Elements of general science met criticism in 1995 by the professor of educational history and culture John M. Heffron for its emphasis on botany and practical applications at the expense of broader scientific principles. He noted that while the text provides detailed coverage of plant processes and their relevance to agriculture and human activities, it allocates limited space to physical sciences, with only 24 out of 302 pages devoted physical principles. He also pointed out that the book's treatment of these physical concepts is somewhat simplified, and focusing more on their practical implications rather than on the underlying scientific theories.
=== General science and future work === Being the first textbook on general science, Elements of General Science contributed to the development of general science movement in US. Following the publication of the textbook, Caldwell undertook field research to assess the extent to which the general science course was being used in various US states. For example, in 1914 and 1915, the graduate student of University of California, Aravilla Meek Taylor under the direction of Otis Caldwell, conducted investigations in the form of surveys in Iowa, were the course was introduced not long before the investigation, and California, where the course was introduced in 1906. In 1920, a few years after the publication of the Elements of General Science, the NEA Commission on the Reorganization of Secondary Schools recommended the introduction of a uniform general science course in the early grades of the secondary school. They called general science as "the science involved in normal human activities, and especially the science involved in the reconstruction period after the war", "the science of common use" and "the science of common sense". As stated in their report, it was not a substitute for any of the special sciences, but "a basis for discovery of interest in special sciences and of vocational opportunity". The same report suggested the books of Caldwell and Eikenberry, including Elements of General Science, as reading and reference books for the teaching of general science. The number of high schools teaching the general science course started to increase and the course became widely adopted in US high school curricula. By 1922, 18.3% of all high school students students in the country were enrolled in a general science course. Within 10 years of the publishing of the first version of the Caldwell and Eikenberry's book on general science, the number of various general science textbooks increased from 1 to 40. As a result of reformations and development of general science, by 1940s high schools adopted a dual tracking system, having two sets of courses with one directed at future college students and the other for non-college students, with the majority of students following the latter one. In the 1950s, after the death of Otis Caldwell, general science course was required in almost every high school and junior high school in the United States.
