Teachers should respond mainly to the content of the journals, and only secondarily to the form. Teachers could correct the language and just note whether or not they were done for evaluation. If grading of language is done, students generally will take no risks. The journal can also be used as a means of developing students' writing skills. See Appendix E for some guidelines and suggestions.
Students can record difficulties they're having doing an activity or benefits they have received.
Specified times will be suggested at various stages within the unit to allow students to write in their journals. They are also an excellent independent study activity. The evaluation should be based on the process of discovering the concept rather than on the content.
