Image Quality and File Size (Updated!)

Students scan an image and adjust the image resolution and file type to see how the changes affect file size.

Application Exercises give students an opportunity to apply concepts they have learned in previous instruction. Work completed by a student will be graded through a variety of scoring options including participation and teacher assessment via rubric to provide flexibility with the type of grade sent to the Learning Management System (LMS) gradebook. Student work may include open-ended questions, correct/incorrect responses, a final product and/or self-assessment.
