Methodology Student Course Performance with Objectives Based Assessment Todd A Zimmerman, Gabriel Hanna - University of Wisconsin-Stout Question: Does an learning objectives based grading system produce different student performance than a points based grading system? Learning Objectives Based Assessment (LOBA) is a grading paradigm, based on Standards Referenced Grading, where student grades are based on demonstrating proficiency of key learning objectives. Students in a LOBA course are given a list of the learning objectives they must demonstrate proficiency on and are given weekly assessments (quizzes) to show their proficiency. A student that has not mastered a learning objective is allowed to reassess as often as needed to master a learning objective. Their final course grade is determined by the number of learning objectives they have demonstrated proficiency on. The benefits of LOBA are: 1)Students know what skills and concepts they must study. 2)Students can learn from their mistakes without any penalty. 3)Students have a stronger incentive to make use of feedback from instructor. 4)More frequent assessment leads to better student outcomes 2. Students are held accountable for demonstrating understanding on the learning objectives in the hopes that they will be more motivated to make take a more active role in their education and to make use of instructor feedback to help master the material.

Thanks to OPID Wisconsin Teaching Fellows and Scholars program and UW-Stout Provost’s office for financial support Conclusions Four sections of University Physics I where split into a control group (points based) and a LOBA group. All lecture sections taught by same instructor Different lab/discussion instructors but all activities dictated by lead instructor During assessment days, points based class did group problem solving on related problems. Common midterm and final given to both groups Force Concept Inventory (FCI) – a 30 question conceptual survey on topics related to Newton’s Laws and Kinematics Given pre- and post-instruction Study habit survey given after midterm and final exams Data analysis: Comparison of FCI scores Comparison of study habit survey results Comparison of exam problem solving skills (in progress).

LOBA students more likely to spend study time on looking at previous assessments and interacting with instructor. With the exception of online homework, Points students more likely to use passive techniques like reading text or viewing videos. LOBA students more likely to make use of instructor feedback and feel better informed of material on assessments. Future research involves analyzing and comparing problem solving skills on exams and comparison to LOBA class with required homework. The FCI measures student understanding of Newton’s Laws and other basic physics principles using a 30 question multiple-choice survey given at start and end of term. ‘Percent Improvement’ is a measure of the fraction of questions initially missed that are answered correctly on post-semester FCI
