Difference between Formative assessment and performance based assessment

When we were in class we were going over different assessments that we may use with our students to make sure they are understanding what we are teaching. In class Dr. Steffes asked us to demonstrate a performance assessment which is and assessment that we use throughout the lesson to understand where our students are clicking at and then recognizing the ones that may need a little bit of our help. Formative assessment to me is the assessment we perform at the end of our lesson such as a test.

~Example 1 will be over performance based assessment:  When teaching the alphabet to a group of students I want to know how many are understanding the example pictures I am showing them with the letter A. So I will print off a worksheet that shows each student the exact pictures that I would show while the class would do it together. I will then ask the students to color in the pictures that start with the letter A as I read them aloud to the class. After the classwork is complete I will then look at the worksheets and see which students are understanding versus which students need a little extra help.

Example 2 over formative based assessment: After we have gone over every letter and the students have completed their worksheets at the end of the unit I will take each student individually back to a table. At this time I will have a paper that shows the letters and pictures we went over I will ask the student to match which picture goes with which letter. This will give me an understanding of how each student interpreted the lesson.
