Why give quizzes in class?

Why not give quizzes in class?

Do you allow quiz or exam corrections?

Why give quizzes in class?

 Myself, as a new instructor:

“Aren’t quizzes just part of teaching?”

 “Gives me an idea of what students are understanding.”

Why give quizzes in class?

 “Incentive for students to keep up to date.”

 “Give students experience taking tests.”

 “Remind students they should be doing homework, even if it isn’t collected.”

Why not give quizzes in class?

 “I don’t want to use class time for quizzes.”

 “Many students are stressed out by quizzes.”

 “There is little correlation between performance on quizzes and exams.”

Why not allow corrections?

 “Students will pass the class due to artificially elevated grades and will not be prepared for their next class.”

 “Students will get in the habit of not studying before a quiz because they know they can complete corrections.”

Motivating Question

 Is it possible to implement a quiz and quiz correction procedure that is a valuable use of in-class time that promotes greater student learning, including a higher level of self-assessment and error analysis, but doesn’t inflate grades?

I think the answer is yes.

 I have adopted a quiz and exam correction procedure created by

Lawrence Morales at Seattle

Central Community College, developed based on a model used in a study done at the City

University of New York.

Objectives

 Minimal in-class time requirement

 Minimize test-anxiety

 Students identify and correct their misconceptions

Objectives

 Students learn to self-assess their strategies and work

 Students revisit incorrect work

 Students keep up with the course material

What does the process look like for quizzes?

Problem Selection

 Select two problems that students frequently get wrong on assessments.

 Inform students why these problems were chosen – they can make the error now and correct it, rather than on a highstakes exam.

Problem Selection

 Two problems that should take no more than 10 minutes total, if students grasp the concept.

 This can help students gauge how fast they will to work on exams.

What feedback to give?

 Minimal marking of specific errors.

 Students learn how to analyze their work and find their own mistakes.

 You have to tell them this, or they will complain.

What feedback to give?

 Make them find a similar problem.

 This helps students learn how to classify what problems are similar to each other and require similar strategies.

How to assign credit?

 Even if they get one problem correct, they get no credit until they correct the other problem.

 Motivates them to do corrections.

How to assign credit?

 If their first attempt at a correction is wrong, they have to do it again.

 I usually ask students to come see me in my office if their first correction is wrong.

Benefits of this process:

 Students learn how to identify their own errors.

 Students learn to classify types of problems by looking for similar problems to the ones they got wrong.

Benefits of this process:

 Students address misconceptions before taking the exam.

 Students become more reflective about their learning process.

Student observations

 “I thought I had prepared enough by looking over the homework and the quizzes, however those did not cover all of the material on the exam. I should have been reading through the book and also doing practice problems in the book. This is something I will be implementing for the next exam.”

Student observations

 “I didn’t mention it much [earlier], but my study habits are clearly not up to par. I’m only just now at that point in school where I can’t just absorb something right away and then throw logic and intuition at it. It’s becoming more and more crucial to legitimately study and practice the material.”

What about the concerns?

 Students will pass the class due to artificially elevated grades and will not be prepared for their next class.

 Students taking classes using the quiz and exam correction procedure are no more likely to pass (or fail) the course than in a regular section. Students are as likely to pass their next class as their peers from a regular section.

What about the concerns?

 “Students will get in the habit of not studying before a quiz because they know they can complete corrections.”

 “A very useful part of the class were the quizzes we had because the hellish process of correcting them made us want to get a perfect score even more .”

Student observations

 “I found [the quiz and test corrections] helpful because it gave me a chance to look over the problems that I missed and really gain a good understanding of where I went wrong.

I think it helped out a lot because in previous classes I just look at the quiz or test and set it down somewhere and forget about it.”

Student observations

 “I think that [correcting my errors] made me know what areas I needed to study more on and when I did the correction the correct way to solve the problem stuck more in my head.”

 “Not only did they improve my grade, but they actually helped me learn!”

Take Away

 Think of a class in which you would like to try this quiz and quiz correction format.

 What questions would you ask?

 Do they elicit common mistakes?

 Are they time appropriate?

 What feedback would you give?

Are there any questions?
