4DX: A Glance at the Math Division WIG

Submitted by Bobbi Mohr on

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

Bueller, Bueller? Engaging Students in a Virtual World

Submitted by Bobbi Mohr on

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.

Scaffolding Handout: Convergence/Divergence Series

Submitted by Becky Baranowski on

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.

ASC STEM Journal Forum - Spring 2020

Submitted by Christopher McNeal on

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.

Limits at Infinity

Submitted by Becky Baranowski on

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.

Mastery Learning for One Exam

Submitted by Becky Baranowski on

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?

College Algebra Exam Review Sessions in ASC

Submitted by Christopher McNeal on

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. 

Laplace Party Spring 2019

Submitted by Christopher McNeal on

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. 

ASC STEM Journal Forum

Submitted by Christopher McNeal on

The Academic Success Center provides in-person tutoring for STEM courses which includes Calculus, Physics, Chemistry, and Biology. Due the discontinuation of Developmental Education courses, there has been a shift in tutoring demand for Gatekeeper and STEM courses in semester Fall 2019. With the collaboration with STEM faculty, the ASC is developing and experimenting new intiatives on how to support the increase in demand of tutoring for these subjects. 

STEM Summer Bridge Program 2019

Submitted by Christopher McNeal on

The program was held during a five week summer session. Twelve students met Monday through Thursday for Math 151 College Algebra/Functions, followed by one hour of tutoring. Students also met Monday through Wednesday for CPD115, Creating College Success in STEM. Every Thursday, students had the opportunity to partake in hands-on STEM workshops and programs, meet current and/or former STEM students, meet with different community professionals to explore the different careers in STEM, and learn about the different supportive programs, such as undergraduate internships.

Extra Practice on derivatives and graphing

Submitted by Jennifer Shannon on

I am hoping that having this extra practice and group work in the long run strengthens not only their ability to do derivatives but also their algebra skills. Unfortuantely I do not have enough time in one semester to do this in every topic we cover, so I am hoping to come up with more creative ways to have them do this practice outside of class, that does not make them complain to me that I am giving them too much homework. 

Investigating Student Misconceptions of Integrals

Submitted by Becky Baranowski on

The purpose of this CATS is to really dive into one concept and try to figure out what students don't understand about basic integration.  Why is everything u-sub?  After each WU, I will use the information to write another WU to go further into the issues students are having.  The goal is to come up with a set of questions/problems that students have to do which "attack" a concept from multiple directions.  If I can cover the concept in many different ways and variations, I hope to fill any and most gaps students may have in their understanding of basic integration.

Rules of Exponents and Fractions are Student's Nemesis in Calculus!

Submitted by Becky Baranowski on

Please note:  From speaking with faculty in the prerequisite coureses, they are incorporating reviews of rules of exponents and fractions.  But, at what detail and how, I am unsure.  Hopefully with the creation of SLOs and having Guided Pathways, we can come up with some activities and best practices as a group to help students understand these two concepts better.  I am not happy with the idea of just accepting that students will not be able to integrate a fractional problem that requires rules of exponents.  There has to be something out there to help our students
