A course book, also known as a textbook or a prescribed textbook, is a written educational resource that provides sequential instruction and content for a specific academic course or subject. It serves as a primary source of information, containing a comprehensive compilation of material, concepts, theories, exercises, examples, and guiding principles that are essential for learning and understanding a particular subject within a structured curriculum.
Typically designed for classroom use, course books are created by subject matter experts and educational publishers to support the learning objectives of a specific course or program. They are systematically organized, with chapters or units that cover different topics in a logical sequence, building upon each other to facilitate progressive learning and the acquisition of knowledge and skills.
Course books often include diagrams, illustrations, charts, graphs, and other visual aids to enhance understanding and to clearly illustrate complex concepts. They may also provide supplementary materials such as exercises, questions, and activities to reinforce learning and allow students to apply their knowledge.
Course books offer a standardized resource among educators and students, ensuring a common understanding and a shared foundation of knowledge within a given course. They provide a structured framework to guide teaching and learning processes, offering a comprehensive and coherent source of information that can be used in conjunction with lectures, discussions, and further readings. Course books are commonly used in educational institutions and form a central part of curriculum development and instructional planning.
The etymology of the word "course book" can be traced back to Middle English and Old French. The word "course" originated from the Old French word "cours", which evolved from the Latin word "cursus", meaning "a running, course, or race". In English, "course" referred to the trajectory of a ship or the path of a person or thing.
On the other hand, the word "book" comes from the Old English word "bōc", which evolved from Proto-Germanic "bōks". This term originally referred to a written document or a collection of writings.
The combination of these two words, "course" and "book", came together to form the modern term "course book", which denotes a book or textbook used in the context of a particular course or educational program.
