Excerpt from Earth Science: A Physiography
The introductory chapter gives a general idea of what has hap pened on the earth and what is going on now, so that the pupil is made aware of the aim of the entire subject. This is followed by a study of the materials of which the earth is made, rocks, and of the forces acting upon those materials. Having learned that much, the pupil is in a position to understand how these forces have modified the earth's surface and made it what it is today.
The land is studied first, because pupils are more likely to know something about land, to begin with. It is for that reason they find land studies easier than the rest of the subject.
This is followed by a short history of the earth, designed to teach the student how the earth came to its present condition. The chapter is optional, but the author feels that many of the better students will be eager to read it.
The study of the land will probably occupy the first half of a year. The pupils who have successfully completed the first half will then study the earth's relations in space, seasons, latitude, longitude, time, the atmosphere and associated phenomena like weather and climate. And the year's work is brought to an end by the study of the sea with special emphasis on harbors.
The text is printed in type of two sizes: larger type for the essential material and smaller for the Optional. Each chapter has a completion summary which the pupil is required to Copy and complete. This avoids the objection that many teachers have to the ordinary summary: that some pupils read only the summary. The completion summary acts as a self-test, for if the pupil is able to fill in the blanks, he knows that he has learned his lesson and this knowledge carries with it a sense of mastery and hence a feeling of satisfaction.
At the end of each chapter are questions on every important point in the text and the teacher may well use these questions as a chief part of his assignment. There is also a set of optional questions which will challenge the best students to extend themselves.
