On this assessment I included a variety of question types, including: multiple choice, true-false, short and long answer. Different students prefer and do better on different types of questions. Using a variety helps make the assessment more accessible to more students.
While students are working on the assessment, I circulate around the classroom to ensure students stay on task and work independently. I answer questions about non-content vocabulary and clarify instructions, but answer little else.
The students have the whole class period to work on the exam. If extra time is needed, I allow them to come back during lunch or after school to complete the exam.
After I grade the assessment, I hand it back to the students and allow them to make test corrections for partial credit. My goal is for the students to learn the concept and correct misconceptions.
