Final answer:
An annotation is a supplemental text added to tasks or resources to provide explanations or comments. It is used in literature classes to facilitate deeper engagement with the text, and in annotated bibliographies to provide summaries and evaluations of sources.
Step-by-step explanation:
A annotation is supplemental text that you can attach to a task, resource, or assignment. In the educational context, particularly in a literature class, students engage in the process of annotating assigned literature as a method of interacting with the text, which enhances their understanding and retention of the material. Various annotation methods can act as tools in a student's learning process. For example, developing a color-coding system for different features of the text or using cross-referencing with a coding system to show relationships between annotations and ideas. When creating an annotated bibliography, remember that it includes additional information such as a description of the work and an evaluation of its validity, reliability, and/or bias. Annotations in this context are meant to summarize, assess, and reflect on the sources used in a research project.
