“Connect microbiology with Learnsmart prep and Smartbook is easy to use; students can easily access it, quickly learn how to get to the material and questions along with any help needed.”

Students’ Retention Improves for Cumulative Final Exams while Grade Averages Increase with Connect SmartBook® and LearnSmart Prep®
Because General Microbiology is a required course and a prerequisite for more specific courses for all Biomedical Science students, Dr. Camilla Ambivero wanted students to better understand course material and to apply their knowledge during the semester and in future courses.
After Ambivero and her colleague implemented Connect Microbiology with LearnSmart Prep and SmartBook, students were required to complete homework assignments for grades.
Students were better able to focus their studies on preparing for exams, and overall class average improved by approximately 2%.
Ambivero says, “Exam grades have increased or stayed the same, while the final exam scores have increased over the semesters. These results show that students are mastering the material and able to recall the information long-term.”
Students agree. One student advises, “Do the homework well in advance and do the work. Don’t just look up the answers. Read the book and do the self-study questions. The more you review, the more prepared you will be for the exams.”
The University of Central Florida, founded in 1963, is a suburban, public institution with an undergraduate enrollment of approximately 59,000 students. Based in Orlando, UCF offers more than 220 degree programs in 13 colleges over ten regional campuses. Researchers at UCF attract nearly $200 million annually in grants, gifts, and sponsored awards, where 956 patents have been secured.
General Microbiology is an introductory course in microbiology for science and pre-professional majors designed to familiarize students with the fundamental concepts of microbiology and the specialized techniques necessary to study microorganisms. The laboratory exercises are designed to develop an ability in the student to carry out the specialized techniques associated with the isolation, cultivation, microscopic examination, and the identification of diverse groups of microorganisms. Attempts will be made throughout the course to use examples that not only illustrate fundamental concepts but also demonstrate to the student the importance of microorganisms to the welfare of all humans. The class objectives are in line with the American Society of Microbiology (ASM).
- Exams 50%
- Homework (SmartBook and LearnSmart Prep) 12.5%
- Lab Component 37.5%
Implementation of McGraw-Hill Connect Microbiology
At the beginning of the semester, Ambivero includes an assignment that is equal to one-third of students’ homework grade in LearnSmart Prep covering chemistry and biology basics. She says, “I give the students three weeks to complete this assignment at the beginning of the semester to ensure that all students are up to the same level of required knowledge.”
Throughout the course, Ambivero gives SmartBook assignments for each chapter covered, and students are required to complete those assignments before the exam. She reminds students that it is in their best interest to do the homework as the course progresses and not wait until the last minute. “Most students who succeed and score well above the average complete the assignments throughout the course,” Ambivero says.
Students are assigned two SmartBook assignments per week that are due the night before an exam, and students are responsible for three to four chapters per exam. Each chapter varies from 5-15 points, but all points are totaled into a pool of points. Each assignment should take about an hour to an hour and a half to complete.
Ambivero notes, “In general microbiology, cell growth, specifically cell wall synthesis, is a challenging topic. The book and the animations help students comprehend the material.”
Ambivero uses data in available reports to review and re-work slides if she notices students have struggled in the homework and exams. In the SmartBook reports, Ambivero uses the “Practice Quiz” reports, the “Connect Insight Dashboard” and the “At-Risk Report” in Connect. The “At-Risk Report” helps identify students who may need extra help. Ambivero says, “Since I only use completion grades for Connect, the at-risk report helps me identify students that I may want to talk to. A few are high achieving students who just do not spend a lot of time on Connect, but most are average and below students. It does not make much sense before the first exam, but it helps with the following exams.”
“Ambivero says Connect allows her to redesign individual sections of the course. She can trust that students will learn some of the material in Connect, so she’s able to focus more of her time and resources on topics that are harder to grasp.
She says, “I now hold students more accountable than before. I do not spend time reviewing terms and defining them in class. I expect students to come to class with some sort of previous knowledge of the material, and we will apply it in class.”
Ambivero compared exam data collected during Summer 2016, Fall 2016, and Fall 2017 semesters prior to homework being implemented as a completion grade versus data collected after homework was implemented as a completion grade during Summer 2018, Fall 2018, and Summer 2019 semesters.
After Connect Microbiology with LearnSmart Prep and SmartBook implementation, final exam scores have increased over the semesters. Connect homework implementation is at the red dotted line (Figure 1).
Exams cover the following material:
- Exam 1 covers the introduction to microbiology with nomenclature, prokaryotes vs eukaryotes, and cell make-up.
- Exam 2 is cellular growth as well as control of microbial growth.
- Exam 3 is metabolism.
- Final exam is cumulative with an emphasis on immunity and pathogenicity.
Ambivero says, “The exam questions are a lot like the homework questions, and I have seen a decrease in ‘complaints’ about the disconnect of the class to exams since using Connect Microbiology with SmartBook.”
Students’ average grades improved over time. Prior to requiring students to complete homework in Connect, students’ average grades ranged from 76.7 to 75 to 75.1 (Figure 2). However, after homework was required to be completed in Connect prior to an exam, students’ scores improved and climbed steadily from 77.4 to 77.9 to 78.3 (Figure 2).
Before requiring homework, the class score average was 75.6; after requiring homework, the class average increased to 77.9 – an improvement of 2.3% overall (Figure 3).
When asked to share suggestions that
might assist peers, Ambivero answered,
“Make sure you explain to students why
you are doing this. I had to add a slide
with before vs. after homework grades to
push students to buy-in. I was still getting
students complaining that there was no
point to the homework - until they saw
the data.” Ambivero worked closely with
her Learning Technology Representative
during the transition to Connect. “Our
Learning Technology Representative
took the time to explain everything to my
colleague and me. My colleague has been
teaching this class for almost 50 years
and with the same book for probably two
decades. It was hard at first to discuss
a change, but when they showed the information and how easy it is, and how
it helps students, it made the transition
easier,” Ambivero adds.
After implementing Connect Microbiology with LearnSmart Prep and SmartBook, students completed homework more consistently and earned higher scores on exams, including cumulative final exams. Overall, the class score average improved from 75.6 to 77.9 – an increase of 2.3%.
Ambivero says, “Connect Microbiology improves students’ overall retention of material. Over the last three course periods, class performance improved consistently with homework incorporated as a grade for completion. More completed homework leads to higher exam grades and improved performance on cumulative final exams.”
Camilla Ambivero has been at the University of Central Florida since 2003, where she completed her undergraduate and graduate degrees and earned her Ph.D. in 2013. Her research interest is mitochondrial function and dysfunction and the effects on the cells and overall health. Ambivero teaches all three semesters, including three levels of microbiology (for majors, non-majors, and pre-nursing), as well as immunology and molecular biology.
