This study explores the implementation and impact of Objective Based Grading (OBG) in a college math classroom, inspired by insights gained from the Maricopa Student Success Conference. After adopting a structured grading approach that included two in-class Mastery Checks, a scale of 0 to 4 for individual concepts, and an emphasis on self-reflection, I observed significant improvements in student engagement and performance. Notably, the number of students seeking retakes on their own increased by nearly 300%, and average scores rose by 18% in Class 1 and 16% in Class 2.

Subjectively, it is believed students are more successful in MAT 151 ONLINE if they can process the information over 16 weeks versus 8 or 5 weeks.  After analyzing the data objectively, students enrolled in Bobbi Mohr's MAT 151 ONLINE courses from Spring 25 to Spring 24, using the same MOER course structure, yield the highest average success rates in 5 week courses.  The collective student success rate average for 5 week classes was 75.4%.

With OPIE data from AY 22-23, MAT instructors have implemented instructional best strategies to improve student retention rates from Fall 23 to Fall 24.  To contribute to the EMCC Strategic Goal of increase college retention and persistence by reducing the within semester withdrawal rate from 16% to 14% by 2026, MAT instructors have implemented and documented (monthly) instructional best practices, as well as reported (monthly) the number of students retained in their courses.

The ET (embedded tutoring) program was not sustained after the 22-23 academic school year.  Student surveys from Spring 22 report 62% of respondents say having an embedded tutor helped them feel comfortable asking for help; 60% of respondents report having an embedded tutor deepened their understanding of course topics and concepts; 49% of respondents report the embedded tutor improved their critical thinking skills.

When finding derivatives using the chain rule, a common student error is to "forget the chain".  By visually confirming the derivative equation they calculated matches the derivative graph generated by Desmos, students can confirm correct rule choice and correct application of rules.  If the graphs don't match, students can then make small changes to their equation until the derivatives match.

In conjunction with the 4DX campus initiative and the EMCC Super Goal #1, the math division developed the following WIG:  To contribute to closing the equity gap and improving a student’s sense of belonging, the Mathematics Division will increase the student’s response average on the twenty questions of the Classroom Community Survey (Rovai, 2002) from a 2.2 to 2.5 by December 2021.  Residential faculty reported what types of activities/practices were implemented in their classes to increase a student's sense of belonging.  Students reported an average

This assessment assesses the CLO of "Students will pick the most appropriate tool/technique to solving a problem" as well as the ILO of written communication. 

In Fall 20, math courses transitioned to a Live Online format versus traditional online. Faculty spent the summer frantically learning technologies and strategies through workshops, brainstorming sessions, and social media. Math faculty also trained one another on Zoom/Webex, NearPod, and Whiteboard.fi with a common goal -  to learn and implement new tools in the virtual environment to keep students engaged; increasing student success and persistence.

Update (1 week after CATS was originally submitted): After submitting this CATS, students began learning about Power Series (which is one reason to learn Convergence/Divergence of series discussed in this CATS).  WIth the scaffolding handout, they were able to come up with how to deteremine convergence/divergence of Power Series on their own!  Again, I typically have to do a lot more lecture, but I didn't.

The STEM program has grown over the past two years, and has caused an increase in tutoring support for Calculus, Physics, Chemistry, and Biology courses. With the implementation of the STEM journal, students are able sufficiently prepare for their courses. The STEM tutors of the Academic Success Center are able to share helpful information and insight, for they went through the same courses and instructors as our current students.

The purpose of this CATS is to explore student withdrawal rates and exam scores from six MAT151 courses across two semesters to determine whether Video Lessons or Journal Entries appear to lead to greater student course retention and improved learning.  

See comments for update to close the loop.  

Update: In Fall 2020 and Spring 2021, I continued to use the scaffolding handout that addressed conceptual understanding of limits at infinity (as described in this CATS). This handout addresses EMCC's ILO of critical thinking along with the CLO of choosing the most appropriate tool/technique to solve a problem. In both Fall and Spring semesters, I had similar results with roughly 75% of students (both semesters) answering the limits at infinity question correctly on the final.

Angela McClure and I worked on this as part of our calc I/phy I learning community.  She and I plan to re-evaluate this in the Spring and I will also try this in the other learning community.  I will be reaching out to some of my calculus colleagues to see if they are interested in trying this with some of our exams that are more "skill" based an not conceptual.  Angela mentioned possibly looking into doing something like this with vectors in PHY121.  Is this worth the time and effort with doing this?  Are students willing to take advantage of this opportunity?

The Academic Success Center (ASC) provides drop-in person tutoring services for mathematics courses at Estrella. On occassion, the ASC holds study sessions for students in nearby classrooms for a more focused, enclosed tutoring session to support students with rigorous topics or upcoming exam reviews. Starting this semester, the sections of College Algebra decided to conduct two major exams and a final based on the course curriculum of MAT151. To help support this endeavor, the tutors of the ASC were prepared to assist students with these major exams. 

Differential Equations is a foundation mathematics class for all Engineering. Many STEM students who major in Engineering will be taking this course at Estrella. Laplace Transforms are part of the MAT276 curriculum and is widely used in the field of electrical engineering. The Academic Success Center provides tutoring support services for STEM courses through in-person tutoring, group study sessions, and content guidance.
